TECHNICAL FIELD
[001] The present invention relates to a suspension device including two telescopic elements. FUNDAMENTAL TECHNIQUE
[002] Suspension devices installed in a vehicle equipped with a vehicle body frame that is tilted in the left-right direction when the vehicle is turning and two front wheels that are disposed in the left-right direction of the body frame of vehicle are known (for example, with reference to patent documents 1, 2, and 3).
[003] The vehicle, equipped with the tiltable vehicle body structure and two front wheels, has a connecting mechanism. The connection mechanism includes cross elements. The connection mechanism also includes a right side rod for supporting a right end portion of an upper cross element and a left side rod for supporting a left end part of the cross element. Intermediate parts of the cross elements are supported using the vehicle body structure in front of a steering axle. The cross elements are supported in the vehicle body structure so as to be rotatable about a geometric axis extending substantially in the anterior-posterior direction of the vehicle body structure. The cross elements are rotated with respect to the vehicle body structure associated with the inclination of the vehicle body structure, where the relative positions of the two front wheels in the up-down direction of the vehicle body are changed. In a straight state of the vehicle body structure, the cross elements are provided above two front wheels in the top-down direction of the vehicle body structure.
[004] The vehicle equipped with the tiltable vehicle body structure and two front wheels include a straight suspension device to support the right front wheel so that the right front wheel is movable in the top-down direction of the car body structure. vehicle and a left suspension device to support the left front wheel so that the left front wheel is movable in the top-down direction of the vehicle body structure. The right suspension device is supported on the right side rod so as to be rotatable about the geometric axis of the right side rod. The left-hand suspension device is supported on the left-hand rod so as to be rotatable about the geometric axis of the left-hand rod. The vehicle described in each of the patent documents 1 and 2 is additionally equipped with a handlebar, a steering axle and a rotation transmission mechanism. The handlebars are attached to the steering axle. The steering axle is supported on the vehicle body structure so as to be rotatable with respect thereto. When the handlebars are turned, the steering axle is also turned. The rotation transmission mechanism transmits the rotation of the steering axle to the right suspension device and left suspension device.
[005] Numerous components to be installed in the vehicle are arranged in and around the right suspension device and the left suspension device. Components are braking components such as brake discs and brake calipers, sensors, mudguards, hoods and wheels. PRIOR ART DOCUMENTS PATENT DOCUMENTS Patent Document 1: U.S. Examined Patent Publication No. 4,351,410 Patent Document 2: Chinese Unexamined Patent Publication No. 101774414A Patent Document 3: WO 2012/007819 SUMMARY OF THE INVENTION PROBLEM OF THE INVENTION TO BE SOLVED
[006] In patent document 1, as seen from the front side of a vehicle in the straight state of the vehicle body structure, a right suspension device includes a right-right telescopic element positioned on the right side of a right front wheel and a right-left telescopic element positioned on the left side of the right front wheel in the left-right direction of the vehicle body structure. As seen from the front side of the vehicle in the straight state of the vehicle body structure, a left suspension device includes a left-right telescopic element positioned on the right side of a left front wheel and a left-left telescopic element positioned on the side left front wheel left in the left-right direction of the vehicle body structure. Each telescopic element includes an outer part and an inner part of which at least one part is inserted into the outer part. The extension/contraction of the telescopic element is the relative movement of the inside with respect to the outside. When the right front wheel passes through a convex portion of the road surface, the right-right telescopic element and the right-left telescopic element extend and contract, and the right front wheel is moved upwards. At that moment, the right-right telescopic element and the right-left telescopic element have a rigidity capable of supporting the load applied from the road surface to the front wheel supported by the same. When the left front wheel passes through the convex part of the road surface, the left-right telescopic element and the left-left telescopic element extend and contract, and the left front wheel is moved upwards. At that moment, the left-right telescopic element and the left-left telescopic element have rigidity capable of supporting the load applied from the road surface to the front wheel supported by the same. As described above, telescopic elements are necessary to provide sufficient rigidity to support the load applied from the road surface to the front wheel supported by the same. The vehicle described in patent document 1 has a configuration capable of sufficiently supporting the loads applied from the road surface to the right front wheel and the left front wheel by the use of four telescopic elements.
[007] However, in patent document 1, as seen from the front side of the vehicle in the straight state of the vehicle body structure, six elements, that is, the right-right telescopic element, the right front wheel, the Right-left telescopic element, the left-right telescopic element, the left front wheel and the left-left telescopic element, are arranged in the left-right direction of the vehicle body structure. Thus, the vehicle described in patent document 1 is large in the left-right direction of the vehicle body structure. As a result, the vehicle described in patent document 1 is large in the left-right direction as six elements are arranged in the left-right direction of the vehicle body structure even though the vehicle can sufficiently support the load applied from the surface. from the road to the right front wheel and left front wheel using the four telescopic elements.
[008] For the purpose of reducing the size of a vehicle in the left-right direction of the vehicle body structure, a vehicle has been proposed in each of patent documents 2 and 3 where, of the four telescopic elements, the right telescopic element- The right one arranged on the right side of the right front wheel and the left-left telescopic element arranged on the left side of the left front wheel are moved into the space between the right front wheel and the left front wheel. The right suspension device according to each of patent documents 2 and 3 includes a right-anterior telescopic element and a right-rear telescopic element disposed on the left side of the right front wheel. Additionally, the left suspension device includes a left-anterior telescopic element and a left-rear telescopic element disposed on the right side of the left front wheel. The vehicle according to each of patent documents 2 and 3 includes four telescopic elements in addition to patent document 1. As a result, the vehicle according to each of patent documents 2 and 3 can sufficiently support the load applied from the road surface to the right front wheel and left front wheel.
[009] However, in a vehicle equipped with the tiltable vehicle body structure and two front wheels, the right front wheel and the right suspension device are rotated around the geometric axis of the right side rod associated with the turn of the handlebar. The left front wheel and left suspension device are rotated around the geometric axis of the left side rod associated with the turn of the handlebars. Additionally, in the vehicle equipped with the tiltable vehicle body frame and two front wheels, the relative positions of the right front wheel and the left front wheel in the top-down direction of the vehicle body frame are changed in association with the tilt of the vehicle body structure in the left-right direction. Similarly, the relative positions of the right suspension device and the left suspension device in the top-down direction are also changed. Additionally, at this time, the distance between the right front wheel and the left front wheel becomes small in the left-right direction of the vehicle body structure. Similarly, the distance between the right suspension device and the left suspension device also becomes small.
[010] The vehicle, according to each of the patent documents 2 and 3, is equipped with four telescopic elements between the right front wheel and the left front wheel. Thus, in particular, when the handlebar is rotated while the vehicle body structure is tilted in the left-right direction, the two telescopic elements of the right suspension device rotating around the geometric axis of the right side rod may interfere with the left front wheel or the two telescopic elements of the left suspension device rotating around the geometric axis of the left side rod. Similarly, when the handlebar is rotated while the vehicle body frame is tilted in the left-right direction, the two telescopic elements of the left suspension device rotating around the axis of the left side rod may interfere with the wheel right front or two telescopic elements of the right suspension device rotating around the geometric axis of the right side rod. To avoid interference, it is necessary to increase the distance between the two telescopic elements of the right suspension device and the two telescopic elements of the left suspension device. Additionally, it is also necessary to increase the distance between the right front wheel and the left front wheel. Thus, on the vehicle according to each of patent documents 2 and 3, although the vehicle size reduction is made by moving the telescopic elements provided on the right side of the right front wheel and on the left side of the left front wheel to the space between the right front wheel and the left front wheel, the size reduction in the left-right direction is not enough as the distance between the right front wheel and the left front wheel becomes large.
[011] The present invention is intended to provide a suspension device including two telescopic elements and is capable of reducing the size of a vehicle equipped with them while ensuring sufficient rigidity to support the load applied from the road surface to the wheel supported by it. MEANS FOR SOLVING THE PROBLEM (1) The suspension device according to the present invention capable of solving the above-mentioned problem is a suspension device including: a first telescopic element including a first outer part and a first inner part of which a end part is inserted into the first outer part, and is capable of extending/contracting by the relative movement of the first inner part with respect to the first outer part; a second telescopic element including a second outer part which is connected to the first outer part and a second inner part of which an end part is inserted into the second outer part and which is connected to the first inner part, and being able to extend and contract by relative movement of the second inner part with respect to the second outer part; a wheel support part capable of supporting a wheel in one of an outer element including the first outer part, the second outer part and an outer connecting part for connecting the first outer part and the second outer part and an inner element including the first inner part, second inner part and an inner connecting part for connecting the first inner part and the second inner part; and a vehicle body support part capable of supporting the other of the outer element and the inner element, in the vehicle body of the vehicle, where the second outer part is formed to be smaller than the first outer part and connected to the first outer part using a plurality of outer connecting parts arranged in the extension and contraction direction of the second telescopic element; the second inner part is formed to be equal to or less than the first inner part and connected to the first inner part using at least one inner connecting part; and the second telescopic element is: viewed from the geometric axis direction of rotation of the wheel supported on the wheel support part, arranged in a position in which the direction of extension and contraction of the second telescopic element is parallel with the direction of extension and contraction of the first telescopic element; and viewed from any vertical direction with respect to the geometric axis of rotation of the wheel supported on the wheel support part, arranged in a position in which the second telescopic element is superimposed on at least part of the first telescopic element.
[012] With this setting, the second outside part is smaller than the first outside part. Additionally, the second inner part is equal to or less than the first inner part. Thus, the stiffness of the suspension device having this configuration can be less than the stiffness of the suspension device according to each of the patent documents 2 and 3 equipped with two telescopic elements having the same size.
[013] However, according to an aspect of the configuration of the present invention, although the second outer part is smaller than the first outer part, the second outer part is connected to the first outer part using the plurality of outer connecting parts arranged in the direction of extension and contraction of the second telescopic element. Additionally, even though the second inner part is equal to or smaller than the first inner part, the second inner part is connected to the first inner part using at least one inner connecting part. As a result, the second telescopic element is connected to the first telescopic element in at least three positions in the extension and contraction direction of the second telescopic element. Additionally, the second telescopic element is disposed in a position in which the direction of extension and contraction of the second telescopic element is parallel to the direction of extension and contraction of the first telescopic element as observed from the direction of the geometric axis of rotation of the wheel. supported on the wheel support part. Furthermore, the second telescopic element is arranged in a position in which the second telescopic element is overlaid by at least part of the first telescopic element as seen from any vertical direction with respect to the geometric axis of rotation of the wheel supported on the support part of wheel.
[014] The first telescopic element includes the first inner part and the first outer part. One end of the first inner part is inserted into the first outer part. In the first telescopic element, the insertion length of the first inner part inserted in the first outer part can be changed. When the first inner part is pulled out from the first outer part, the insertion length of the first inner part inserted into the first outer part becomes short.
[015] When the insertion length of the first inner part inserted into the first outer part becomes short, the first telescopic element can be bent by the force exerted in the vertical direction with respect to the longitudinal length of the first telescopic element. When the load applied from the road surface to the wheel is transmitted to the suspension device, the force exerted in the vertical direction with respect to the longitudinal length is applied to the first telescopic element. In particular, since the first outer part is a cylindrical element, when the force exerted in the vertical direction with respect to the longitudinal length is applied to the first telescopic element, the first outer part must be bent.
[016] Thus, in the suspension device according to the present invention, the second telescopic element is connected to the first telescopic element so that the rigidity against the force exerted in the vertical direction with respect to the longitudinal length of the first telescopic element is increased by the second telescopic element. In other words, the second telescopic element has a so-called "splint function" to suppress the deformation of the first totelescopic element. As a result, the suspension device can guarantee sufficient rigidity to support the load applied from the road surface to the wheel supported by the same.
[017] With this setting, the second outer part is smaller than the first outer part. Additionally, the second inner part is equal to or less than the first inner part. In this way, in case the suspension device according to the present invention is installed in the vehicle, the interference of the two telescopic elements of the right suspension device with the left front wheel or the two telescopic elements of the left suspension device can be avoided easily. Similarly, the interference of the two telescopic elements of the left suspension device with the right front wheel or the two telescopic elements of the right suspension device can be easily avoided. As a result, the vehicle equipped with the suspension device may be reduced in size.
[018] Thus, with this configuration, the vehicle equipped with the suspension device can have its size reduced while ensuring sufficient rigidity to support the load applied from the road surface to the supported wheel.
[019] It is preferable that the suspension device according to the present invention has the following configuration: (2) The second outer part is: shorter than the first outer part in the direction of extension and contraction of the second telescopic element; and connected to the first outer part using the plurality of outer connecting parts arranged in the extension and contraction direction of the second telescopic element.
[020] With this configuration (2), since the first outer part of the second telescopic element, which is larger in diameter than the second inner part, is shorter, the second telescopic element can be shortened more than the first element telescopic. Additionally, since the second outer part is connected to the first outer part using the plurality of outer connecting parts arranged in the extension and contraction direction of the second telescopic element, the reduction in stiffness can be suppressed. In this way, in case the suspension device according to the present invention is installed in the vehicle, the interference of the two telescopic elements of the right suspension device with the left front wheel or the two telescopic elements of the left suspension device can be avoided easily. Similarly, the interference of the two telescopic elements of the left suspension device with the right front wheel or the two telescopic elements of the right suspension device can be easily avoided. As a result, the vehicle equipped with the suspension device may be further reduced in size. Thus, with this configuration, the vehicle equipped with the suspension device can be reduced in size while ensuring sufficient rigidity to support the load applied from the road surface to the supported wheel.
[021] It is preferable that the suspension device according to the present invention has the following configuration. (3) The second telescopic element is shorter than the first telescopic element, and at least one of the first telescopic element and the second telescopic element comprises a component support part capable of supporting the components in a concave part, which is formed by the first telescopic element and the second telescopic element as seen from the direction of the geometric axis of rotation of the wheel supported on the wheel support part.
[022] Typically, the component support part capable of supporting the components to be installed in the vehicle is provided around the first telescopic element and the second telescopic element. With this configuration (3), since the second telescopic element is shorter than the first telescopic element, the concave part is formed using the first telescopic element and the second telescopic element in the end parts in the longitudinal directions as noted in from the direction of the geometric axis of rotation of the wheel supported on the wheel support part. The component support part capable of supporting the components to be installed in the vehicle is provided in the concave part. For this reason, the suspension device including the component support part can be reduced in size. In this way, in case the suspension device according to the present invention is installed in the vehicle, the interference of the two telescopic elements of the right suspension device with the left front wheel or the two telescopic elements of the left suspension device can be avoided easily. Similarly, the interference of two telescopic elements of the left suspension device with the right front wheel or two telescopic elements of the right suspension device can be easily avoided. As a result, the vehicle equipped with the suspension device may be further reduced in size. Thus, with this configuration, the vehicle equipped with the suspension device can be reduced in size while ensuring sufficient rigidity to support the load applied from the road surface to the supported wheel.
[023] It is preferable that the suspension device according to the present invention has the following configuration: (5) The inner connecting part connects the other end part of the first inner part to the other end part of the second inner part .
[024] With this configuration (5), since the inner connecting part connects the other end part of the first inner part to the other end part of the second inner part, the concave part is formed on an end side of the second element telescopic which is shorter than the first telescopic element. Since the component support part can be formed using the concave part, the space can be efficiently utilized, and the hanging device can be reduced in size. Thus, in case the suspension device according to the present invention is installed in the vehicle, interference of the two telescopic elements of the right suspension device with the left front wheel or the two telescopic elements of the left suspension device may be easily avoided. Similarly, interference of the two telescopic elements of the left suspension device with the right front wheel or two telescopic elements of the right suspension device can be easily avoided. As a result, the vehicle equipped with the suspension device may be further reduced in size. Thus, with this configuration, the vehicle equipped with the suspension device can be reduced in size while ensuring sufficient rigidity to support the load applied from the road surface to the supported wheel.
[025] It is preferable that the suspension device according to the present invention has the following configuration. (6) The wheel support part is provided on the outer element and the vehicle body support part is provided on the inner element.
[026] The direction of load transmitted from the wheel to the wheel support part changes depending on the direction of the wheel and the inclination of the vehicle. Thus, when an attempt is made to provide the necessary rigidity to the wheel support part, the wheel support part tends to increase.
[027] With this configuration (6), since the first external part and the second external part are connected using the plurality of external connecting parts, the rigidity of the external element is high. Since the wheel support part is provided on the outer element having high rigidity, the wheel can be supported with high rigidity. Additionally, since the outer element is larger than the inner element, the wheel support part can be formed using a simple structure by providing a hole to the outer element, for example. For this reason, the suspension device can be reduced in size. In this way, in case the suspension device according to the present invention is installed in the vehicle, the interference of the two telescopic elements of the right suspension device with the left front wheel or the two telescopic elements of the left suspension device can be avoided easily. Similarly, interference of the two telescopic elements of the left suspension device with the right front wheel or the two telescopic elements of the right suspension device can be easily avoided. As a result, the vehicle equipped with the suspension device may be further reduced in size. Thus, with this configuration, the vehicle equipped with the suspension device can be reduced in size while ensuring sufficient rigidity to support the load applied from the road surface to the supported wheel.
[028] Furthermore, since the wheel support part is provided in the concave part formed using the first telescopic element and the second telescopic element which is shorter than the first telescopic element, the suspension device can be reduced in size. Thus, in case the suspension device according to the present invention is installed in the vehicle, the interference of the two telescopic elements of the right suspension device with the left front wheel or two telescopic elements of the left suspension device can be avoided with facility. Similarly, interference of the two telescopic elements of the left suspension device with the right front wheel or the two telescopic elements of the right suspension device can be easily avoided. As a result, the vehicle equipped with the suspension device may be reduced in size. Thus, with this configuration, the vehicle equipped with the suspension device can be reduced in size while ensuring sufficient rigidity to support the load applied from the road surface to the supported wheel.
[029] It is preferable that the suspension device according to the present invention has the following configuration. (7) The inner connecting part connects the other end part of the first inner part to the other end part of the second inner part; and the vehicle body support part is provided in the inner connecting part.
[030] With this configuration (7), since the inner connection part connects the other end part of the first inner part to the other end part of the second inner part, the distance between the first inner part and the second inner part can be made small. For this reason, the suspension device can be reduced in size. In this way, in case the suspension device according to the present invention is installed in the vehicle, the interference of two telescopic elements of the right suspension device with the left front wheel or the two telescopic elements of the left suspension device can be avoided easily. Similarly, interference of the two telescopic elements of the left suspension device with the right front wheel or the two telescopic elements of the right suspension device can be easily avoided. As a result, the vehicle equipped with the suspension device may be further reduced in size. Thus, with this configuration, the vehicle equipped with the suspension device can be reduced in size while ensuring sufficient rigidity to support the load applied from the road surface to the supported wheel.
[031] It is preferable that the suspension device according to the present invention has the following configuration. (8) The vehicle body support part is provided in the outer element.
[032] Since the outside is larger than the inside, it must interfere with the wheel. However, with this configuration (8), the wheel support part is provided on the inner element and the vehicle body support part is provided on the outer element. In other words, since the outer part is arranged away from the wheel, the left and right suspension devices can be arranged close together, and the vehicle width can be decreased. In this way, in case the suspension device according to the present invention is installed in the vehicle, the interference of two telescopic elements of the right suspension device with the left front wheel or the two telescopic elements of the left suspension device can be avoided easily. Similarly, interference of the two telescopic elements of the left suspension device with the right front wheel or the two telescopic elements of the right suspension device can be easily avoided. As a result, the vehicle equipped with the suspension device may be reduced in size. Thus, with this configuration, the vehicle equipped with the suspension device can be reduced in size while ensuring sufficient rigidity to support the load applied from the road surface to the supported wheel.
[033] It is preferable that the suspension device according to the present invention has the following configuration: (9) The vehicle body support part is provided in the first external part.
[034] With this configuration (9), the vehicle body support part is configured using the first outer part which is larger than the second outer part. For this reason, the suspension device can be reduced in size. Thus, in case the suspension device according to the present invention is installed in the vehicle, interference of the two telescopic elements of the right suspension device with the left front wheel or the two telescopic elements of the left suspension device may be easily avoided. Similarly, interference of the two telescopic elements of the left suspension device with the right front wheel or the two telescopic elements of the right suspension device can be easily avoided. As a result, the vehicle equipped with the suspension device may be further reduced in size. Thus, with this configuration, the vehicle equipped with the suspension device can be reduced in size while ensuring sufficient rigidity to support the load applied from the road surface to the supported wheel.
[035] It is preferable that the suspension device according to the present invention has the following configuration. (10) The inner connecting part connects the other end part of the first inner part to the other outer part of the second inner part in the same position in the extension and contraction direction of the second telescopic element.
[036] With this setting (10), the inner connection part can be made small. For this reason, the suspension device can be reduced in size. In this way, in case the suspension device according to the present invention is installed in the vehicle, the interference of the two telescopic elements of the right suspension device with the left front wheel or the two telescopic elements of the left suspension device can be avoided easily. Similarly, interference of the two telescopic elements of the left suspension device with the right front wheel or the two telescopic elements of the right suspension device can be easily avoided. As a result, the vehicle equipped with the suspension device may be further reduced in size. Thus, with this configuration, the vehicle equipped with the suspension device can be reduced in size while ensuring sufficient rigidity to support the load applied from the road surface to the supported wheel.
[037] This configuration (10) is preferably combined with those mentioned above (3), (4), (5), (6), (7), (8) and (9). With this configuration (10), the concave part formed using the first telescopic element and the second telescopic element can be enlarged. For this reason, the suspension device can be reduced in size. In this way, in case the suspension device according to the present invention is installed in the vehicle, the interference of the two telescopic elements of the right suspension device with the left front wheel or the two telescopic elements of the left suspension device can be avoided easily. Similarly, interference of the two telescopic elements of the left suspension device with the right front wheel or the two telescopic elements of the right suspension device can be easily avoided. As a result, with this configuration, the vehicle equipped with the suspension device can be reduced in size while ensuring sufficient rigidity to support the load applied from the road surface to the supported wheel.
[038] It is preferable that the suspension device according to the present invention has the following configuration: (1) The second inner part is formed to be smaller than the first inner part in the vertical direction with respect to the extension direction and contraction of the second telescopic element as observed from the geometric axis direction of rotation of the wheel supported on the wheel support part and is also formed as being smaller than the first inner part in the vertical direction with respect to the direction of extension and contraction of the second telescopic element as viewed from any vertical direction with respect to the geometric axis of rotation of the wheel supported on the wheel support part.
[039] With this configuration (11), since the inner part of the second telescopic element is small, the outer part can also be made small. Additionally, the internal connection part can also be shortened. For this reason, the suspension device can be reduced in size. In this way, in case the suspension device according to the present invention is installed in the vehicle, the interference of the two telescopic elements of the right suspension device with the left front wheel or the two telescopic elements of the left suspension device can be avoided easily. Similarly, interference of the two telescopic elements of the left suspension device with the right front wheel or two telescopic elements of the right suspension device can be easily avoided. As a result, the vehicle equipped with the suspension device may be further reduced in size. Thus, with this configuration, the vehicle equipped with the suspension device can be reduced in size while ensuring sufficient rigidity to support the load applied from the road surface to the supported wheel. ADVANTAGE OF THE INVENTION

[057] The vehicle according to each of patent documents 2 and 3 can sufficiently support the loads applied from the road surface to the right front wheel and the left front wheel. Vehicle size reduction according to each patent document 2 and 3 in the left-right direction is achieved by moving the telescopic elements provided on the right side of the right front wheel and on the left side of the left front wheel to the space between the wheel right front and left front wheel. However, downsizing in the left-right direction is not enough as the distance between the right front wheel and left front wheel becomes large. In order to obtain the size reduction of the vehicle equipped with the telescopic elements while ensuring sufficient rigidity to support the loads applied from the road surface to the wheels supported by the same, the inventors of the present invention studied the loads applied to the elements. telescopic. As a result of this, the inventors have found that the greatest load among the loads applied to the telescopic elements is the load applied in the vertical direction with respect to the geometric axis of rotation of the wheel supported on the wheel support part. The inventors of the present invention have concluded that the suspension device of the vehicle merely needs to have a configuration capable of sufficiently supporting the load applied in the vertical direction with respect to the geometric axis of rotation of the wheel supported on the supporting part of the wheel.
[058] So, the inventors of the present invention first directed attention to the presentation of the telescopic elements. In the vehicle according to patent document 1, six elements, i.e. the right-right telescopic element, the right front wheel, the right-left telescopic element, the left-right telescopic element, the left front wheel and the element left-left telescopic, are arranged in the left-right direction of the vehicle body structure. With this arrangement, for example, since the right front wheel is supported on the right-right telescopic element and the right-left telescopic element on the left and right side, the right-right telescopic element and the right-left telescopic element have , preferably, the same rigidity. Similarly, the left-right telescopic element and the left-left telescopic element preferably have the same rigidity.
[059] However, in the vehicle according to each of patent documents 2 and 3, the right suspension device is equipped with a right-front telescopic element and a right rear telescopic element arranged on the left side of the right front wheel. Additionally, the left-hand suspension device is equipped with a left-front telescopic element and a left-rear telescopic element arranged on the right side of the left front wheel. Here, the inventors discovered that the right-anterior telescopic element and the right-rear telescopic element need not necessarily have the same rigidity. Similarly, the inventors have also discovered that the left-anterior telescopic element and the left-rear telescopic element need not necessarily have the same rigidity.
[060] Each telescopic element includes an inner element and an outer element. An end of the inner element is inserted into the outer element. In the telescopic element, the insertion length of the inner element into the outer element can be changed. When the inner element is pulled out of the outer element, the insertion length of the inner element inserted into the outer element becomes short.
[061] When the insertion length of the inner element inserted into the outer element becomes short, the telescopic element may bend by a force applied in the vertical direction with respect to the longitudinal direction of the telescopic element. When the load applied from the road surface to the wheel is transmitted to the suspension device, the force applied in the vertical direction with respect to the longitudinal direction is exerted on the telescopic element. The telescopic element must be of rigidity capable of supporting this load in a state in which the inner element is pulled out of the outer element as much as possible.
[062] So, the inventors of the present invention paid attention to the function of the telescopic element. Normally, in case vehicle downsizing in the left-right direction is desired, only the first telescopic element needs to be used instead of providing the second telescopic element. However, if an attempt is made to ensure sufficient rigidity using only the first telescopic element, the first telescopic element becomes large in diameter and becomes long, where the first telescopic element becomes very large.
[063] Accordingly, the inventors of the present invention realized that when the first telescopic element receives the load in the vertical direction with respect to the geometric axis of rotation of the wheel supported on the wheel support part, a function to increase its rigidity is merely required for the second telescopic element. Additionally, the inventors have considered that the second telescopic element preferably has a function of suppressing the deformation of the first telescopic element due to the load applied from the road surface to the supported wheel, i.e. the so-called splint function. The inventors also thought that the size of the second telescopic element could be reduced by designing a suspension device in which the second telescopic element serves as an element having a splint function rather than an element having a wheel support function. .
[064] As a result of the study, the inventors of the present invention discovered the following configuration. The second outer part is made smaller than the first outer part and connected to the first outer part using a plurality of outer connecting parts arranged in the extension/contraction direction of the second telescopic element. Additionally, the second inner part is made equal to or smaller than the first inner part and connected to the first inner part using at least one inner connecting part. In this way, the second telescopic element is connected to the first telescopic element in at least three positions in the extension and contraction direction of the second telescopic element. Furthermore, the second telescopic element is arranged in a position in which the direction of extension and contraction of the second telescopic element is parallel to the direction of extension and contraction of the first telescopic element as observed from the direction of geometric axis of rotation of the wheel supported on the wheel support part. Additionally, the second telescopic element is arranged in a position in which the second telescopic element is superimposed on at least part of the first telescopic element as viewed from any vertical direction with respect to the geometric axis of rotation of the wheel supported on the support part of wheel. In this way, the second telescopic element has a function of suppressing the deformation of the first telescopic element due to the load applied from the road surface to the supported wheel, that is, the so-called splint function. For that reason, the suspension device can guarantee sufficient rigidity to support the load applied from the road surface to the supported wheel. Additionally, the second outer part is made smaller than the first outer part and the second inner part is made equal to or smaller than the first inner part. Thus, in case the suspension device according to the present invention is installed in the vehicle, the interference of two telescopic elements of the right suspension device with the left front wheel or two telescopic elements of the left suspension device can be avoided with facility. Similarly, interference of the two telescopic elements of the left suspension device with the right front wheel or the two telescopic elements of the right suspension device can be easily avoided. As a result, the vehicle equipped with the suspension device may be reduced in size.
[065] With this configuration, the vehicle equipped with the suspension device can be reduced in size while ensuring sufficient rigidity to support the load applied from the road surface to the supported wheel.
[066] The inventors of the present invention have adopted the configuration that is considered disadvantageous from the standpoint of rigidity while aware that such configuration is disadvantageous. The configuration is disadvantageous in that the second outer part is made smaller than the first outer part and the second inner part is made equal to or smaller than the first inner part. The inventors of the present invention assumed that the configuration was not considered conventional as it is disadvantageous from the standpoint of rigidity. The inventors were able to change the way of thinking as the inventors realized that the splint function is only necessary for the second telescopic element through their study. This is an idea not gained from just worrying about the stiffness needed for a suspension device to support a wheel, and it's the best idea gained as a result of worrying about both stiffness and downsizing in the left-right direction.

TARGETING OPERATION
[097] Figure 4 is a view illustrating the steering operation of vehicle 1001 and is a plan view illustrating the front of the vehicle in a state in which vehicle 1001 is steered.
[098] As illustrated in Figure 4, when the handlebar 1023 is turned in the left to right direction, the steering force transmission mechanism 1006 of the steering mechanism 1007 is operated, and a steering operation is performed.
[099] For example, when steering shaft 1060 is rotated in the direction of arrow T in figure 4, tie rod 1067 is moved in the left direction to the back. The first bracket 1317 and the second bracket 1327 are rotated in the direction of the arrow T in accordance with the movement of the tie rod 1067 in the left-back direction. When the first support 1317 and the second support 1327 are rotated in the direction of the arrow T, the first front wheel 1031 is rotated about the first central geometric axis Y1 (reference to Figure 2) and the second front wheel 1032 is rotated about the second central geometric axis Y2 (refer to figure 2). TILT OPERATION
[0100] Figure 5 is a view illustrating the tilting operation of vehicle 1001 and is a front view illustrating the front of the vehicle in a state in which vehicle 1001 is tilted.
[0101] As illustrated in figure 5, according to the operation of the link mechanism 1005, the vehicle 1001 is tilted in the left-right direction. The operation of the connection mechanism 1005 means that the respective elements (the first cross element 1051, the second cross element 1052, the first side element 1053 and the second side element 1054) for performing the tilting operation on the connection mechanism 1005 are rotated with respect to their respective connection points and the format of connection mechanism 1005 is changed.
[0102] In the connection mechanism 1005 of this mode, for example, in the straight state of the vehicle, the first cross element 1051, the second cross element 1052, the first side element 1053 and the second side element 1054 are arranged to form a substantially rectangular shape in a front view, but in the tilted state of vehicle 1001, the shape is deformed into a shape substantially close to a parallelogram. The connection mechanism 1005 performs a tilting operation associated with the relative rotation operations of the first cross member 1051, the second cross member 1052, the first side member 1053, and the second side member 1054, thus tilting the first front wheel 1031 and the second front wheel 1032.
[0103] For example, when the occupant tilts vehicle 1001 to the left, the front tube 1211 is tilted to the left with respect to the vertical direction. When the front tube 1211 is tilted, the first cross element 1051 is rotated with respect to the front tube 1211 around the support part C and the second cross element 1052 is rotated with respect to the front tube 1211 around the support part F. As a result, the first cross element 1051 is moved more to the left than the second cross element 1052, and the first side element 1053 and the second side element 1054 are angled with respect to the vertical direction while being in parallel with the front tube. 1211. When the first side element 1053 and the second side element 1054 are tilted, the first side element 1053 and the second side element 1054 are rotated with respect to the first cross element 1051 and the second cross element 1052. vehicle 1001 is tilted, first front wheel 1031 and second front wheel 1032 supported on first side member 1053 and second side member 1054 are supported on first side member 1053. respectively inclined with respect to the vertical direction while being parallel to the front tube 1211 in accordance with the inclination of the first side member 1053 and the second side member 1054.
[0104] Additionally, tie rod 1067 maintains its posture that is parallel to that of first cross element 1051 and second cross element 1052 even when vehicle 1001 is tilted.
[0105] As described above, the connecting mechanism 1005 for tilting the first front wheel 1031 and the second front wheel 1032 by performing the tilting operation is disposed above the first front wheel 1031 and the second front wheel 1032. In other words, the geometric axes of rotation of the first cross member 1051, the second cross member 1052, the first side member 1053 and the second side member 1054 constituting the connecting mechanism 1005 are arranged above the first front wheel 1031 and the second front wheel 1032. STEERING OPERATION + TILT OPERATION
[0106] Figure 6 is a front view illustrating the front of the vehicle in a state in which vehicle 1001 is steered and tilted. Figure 6 illustrates a state in which the vehicle is steered to the left and tilted to the left. At the time of operation illustrated in Figure 6, the directions of the first front wheel 1031 and the second front wheel 1032 are changed by the steering operation, and the first front wheel 1031 and the second front wheel 1032 are tilted along with the body structure of vehicle 1021 by tilting operation. In this state, the shape formed by the first cross element 1051, the second cross element 1052, the first side element 1053 and the second side element 1054 of the connecting mechanism 1005 is deformed into a shape substantially close to a parallelogram, and the tie rod 1067 is moved left or right depending on the steering direction (left in figure 6) and backward. SHOCK ABSORBER STRUCTURE
[0107] Figure 7 is a side view illustrating the first shock absorber 1033 as viewed from the right side of vehicle 1001 of Figure 1. Figure 7 is a side view illustrating the first shock absorber 1033 as viewed from the right in the left direction. -right of vehicle 1001 of Figure 1. Figure 7 is a side view illustrating the first shock absorber 1033 as viewed from the direction of the axis of rotation of the first front wheel 1031 supported using the first shock absorber 1033. For example, the shapes and arrangements of the second damper 1034, the second front wheel 1032 and various elements disposed therein are symmetrical to those of the first front wheel 1031 in the left-right direction. Therefore, the respective parts of the second front wheel 1032 are described using parent numeral references in Figure 7. FIRST SHOCK ABSORVER

[0110] The first telescopic element 1331 has an extension and contraction structure so as to extend and contract in the direction of the first central geometric axis Y1.

The second sensing part 1822 is arranged such that at least part of it is superimposed on the extension line in the extension and contraction direction of the fourth telescopic element 1342. BENEFITS
[0165] In the first embodiment mentioned above, the first telescopic element 1331 and the second telescopic element 1332 are connected using the first support 1317 in its upper end parts. In this way, the first support 1317 functions as a rotation stop for the first telescopic element 1331 and the second telescopic element 1332. Similarly, since the third telescopic element 1341 and the fourth telescopic element 1342 are connected using the second support 1327 in its upper end portions, the second support 1327 functions as a rotation stop for the third telescopic element 1341 and the fourth telescopic element 1342. As a result, the first front wheel 1031 and the second front wheel 1032 can be rotated to steering directed by steering movement without idle. Therefore, a structure to support the front wheels is obtained using a simple configuration.
[0166] Additionally, in the first mode mentioned above, the first damper 1033 including the first support 1317 is rotated in accordance with the rotation of the steering element 1028 and is disposed on the left side of the vehicle 1001 in the left-right direction thereof. . Since the second telescopic element 1332 is made smaller than the first telescopic element 1331, the front part of the vehicle 1001 can be prevented from being enlarged.
[0167] Additionally, similarly, the second damper (an example of the second support element) 1034 including the second support 1327 is rotated in accordance with the rotation of the steering element 1028 and is disposed on the right side of the vehicle 1001 in the direction left-right of it. Since the fourth telescopic element 1342 is made smaller than the third telescopic element 1341, the front part of the vehicle 1001 can be prevented from being enlarged.
[0168] Thus, with the configuration mentioned above, the increase in the size of the front part of vehicle 1001 can be prevented while the support structure of the front wheel having the rotation interruption function is obtained using the simple configuration.
[0169] In addition, the first shock absorber 1033 supports the first front wheel 1031 using the two telescopic elements, that is, the first telescopic element 1331 and the second telescopic element 1332, connected to each other. In this way, the first damper 1033 can support the first front wheel 1031 while having high rigidity against the input of force to the first front wheel 1031 during the vehicle 1001 in motion. Furthermore, similarly, the second damper 1034 supports the second front wheel 1032 using two telescopic elements, i.e. the third telescopic element 1341 and the fourth telescopic element 1342, connected to each other. In this way, the second shock absorber 1034 has a high rigidity against the force imposed on the second front wheel 1032 during the movement of the vehicle 1001.
[0170] Still further, in vehicle 1001, the first support 1317 and the second support 1327 are superimposed with part of the vehicle body cover 1022 as seen from the side of the vehicle 1001. With the vehicle 1001 configured as described above, first support 1317 and second support 1327 are moved up and down with respect to vehicle body structure 1021 and vehicle body cover 1022. Thus, first support 1317 and second support 1327 are required to interference with the first support 1317 and the second support 1327 is avoided. As a result, in vehicle 1001, in particular, the reduction in size of the first support 1317 and the second support 1327 contributes to the suppression of the increase in size of the vehicle 1001 .
[0171] In the first embodiment mentioned above, the upper part of the first telescopic element 1331 and the upper part of the second telescopic element 1332 are connected using the first support 1317, and the second telescopic element 1332 is shorter than the first telescopic element 1331.
[0172] With this configuration, a certain space is guaranteed below the lower end part of the second telescopic element 1332. In this way, other elements (for example, the axle support part) can be arranged in the space below the second telescopic element 1332. As a result, the first telescopic element 1331 and the second telescopic element 1332 can be arranged so that they can approach each other, and the first support 1317 can be prevented from being enlarged.
[0173] Similarly, a certain space is guaranteed below the lower end part of the fourth telescopic element 1342. In this way, other elements can be arranged in the space below the fourth telescopic element 1342. As a result, the third telescopic element 1341 and the fourth telescopic element 1342 can be arranged to be brought closer together, and the second support 1327 can be prevented from being enlarged. For these reasons, the raising of the front part of the vehicle 1001 can be prevented while the front wheel support structure having the rotation stop function is obtained using the simple configuration.
[0174] Additionally, since space is guaranteed below the lower end part of the second telescopic element 1332, the degree of freedom of design in the arrangement of the various components, such as the first sensor holder 1814 of the first wheel speed sensor 1081, is perfected. Similarly, since space is guaranteed below the lower end portion of the fourth telescopic element 1342, the degree of freedom for design in the arrangement of various components, such as the second wheel speed sensor 1082 of the second sensor holder 1824, is perfected.
[0175] However, on a vehicle including two front wheels that are supported using two suspension devices, each including two telescopic elements, in case an axle support part is arranged close to the telescopic elements, the part of axle support can be prevented from being increased while the rigidity of the axle is guaranteed. For this reason, in patent documents 2 and 3, such axle support part is arranged between two telescopic elements, where the axle support part is prevented from being increased in the upwards-lower direction as a necessary extension and contraction step Granted. However, in this configuration, since there is a guarantee restriction of a space for accommodation of the axle support part, it is difficult to arrange the two telescopic elements while the elements are brought closer together. As a result of this, a support for connecting the upper end parts of the two telescopic elements being spaced apart from each other is increased.
[0176] However, in the first embodiment mentioned above, since the first axis support part 1333 is arranged below the second telescopic element 1332, the first telescopic element 1331 and the second telescopic element 1332 can be easily arranged close to each other , where the first support 1317 can be prevented from being raised. Similarly, since the second axle support part 1343 is disposed below the fourth telescopic element 1342, the second support 1327 can be prevented from being enlarged. In this way, the raising of the front part of the vehicle 1001 can be prevented while the front wheel support structure having the rotation interruption function is obtained using the simple configuration.
[0177] In the first mode mentioned above, since the first telescopic element 1331 having the first insertion length I1 has sufficient performance in the orientation function (the suppression of displacement in directions other than the direction of extension and contraction) for movement of extension and contraction along the extension and contraction direction of the first telescopic element 1331 and the second telescopic element 1332, the second insertion length 12 is shortened, where the second telescopic element 1332 becomes easy to be shortened. Similarly, since the third telescopic element 1341 having the third insertion length I3 has sufficient performance in the orientation function (at displacement pressure in directions other than the extension and contraction direction) for the extension and contraction movement along the direction of extension and contraction of the third telescopic element 1341 and the fourth telescopic element 1342, the fourth insertion length I4 is shortened, where the fourth telescopic element 1342 becomes easy to be shortened. MODIFICATION MODE FIRST SHOCK ABSORVER
[0178] Figure 8 is a side view illustrating the first shock absorber 1033 as seen from the second front wheel 1032 of vehicle 1001 acode with a modality of modification. Figure 8 is a side view illustrating the first shock absorber 1033 as viewed from the right of vehicle 1001 in the left-right direction according to the modality of modification. In this modification, the shapes and positions of the respective elements disposed in the second damper 1034 and the second front wheel 1032 are symmetrical with those disposed in the first damper 1033 and the first front wheel 1031. Therefore, the respective parts of the second front wheel 1032 are described using the numerical references in figure 8.
[0179] As illustrated in Figure 8, in the modality of modification, the outer diameter of a second telescopic element 1332A (an example of the second telescopic element according to the present invention) constituting the first damper 1033 is made smaller than the outer diameter of the first telescopic element 1331. More specifically, the length W2 of the second inner element 1332b1 (an example of the second inner part according to the present invention) of the second telescopic element 1332A in the vertical W direction with respect to the first central geometric axis Y1 is longer shorter than the length W1 of the first inner element 1331b of the first telescopic element 1331 when the first damper 1033 is viewed from the second front wheel 1032. Similarly, the outer diameter of the second outer element 1332a1 (an example of the second outer element according to the present invention) of the second telescopic element 1332A is made smaller than the first and outer element 1331a of the first telescopic element 1331. More specifically, the length of the second outer element 1332a1 of the second telescopic element 1332A in the vertical W direction with respect to the first central geometric axis Y1 is shorter than the length of the first outer element 1331a of the first telescopic element 1331 when the first damper 1033 is viewed from the second front wheel 1032.
[0180] The second outer member 1332a1 includes a second outer main body 1332c1, a second upper support part 1332d1 and a second lower support part 1332e1. The second outer main body 1332c1 allows the second inner element 1332b1 to be inserted in the direction of extension and contraction thereof.
[0181] The second upper support part 1332d1 and the second lower support part 1332e1 are arranged in the extension and contraction direction of the second telescopic element 1332A on the side of the second outer main body 1332c1.
[0182] The first inner element 1331b and the second inner element 1332b1 are connected to each other. The first inner element 1331b and the second inner element 1332b1 are connected using a first bracket 1317A. The upper end portion of the first inner element 1331b in the extension and contraction direction thereof and the upper end portion of the second inner element 1332b1 in the extension and contraction direction thereof are connected using the first support 1317A. The first outer element 1331a and the second outer element 1332a1 are connected using a plurality of connecting parts. The first outer element 1331a and the second outer element 1332a1 are connected using a first connecting part 1351A (an example of the outer connecting part according to the present invention) and a second connecting part 1352A (an example of the outer connecting part according to the present invention).
[0183] The first connecting part 1351A and the second connecting part 1352A are arranged in the direction of extension and contraction of the second telescopic element 1332A. The first connecting part 1351A is arranged in the intermediate part of the second telescopic element 1332A in the direction of extension and contraction thereof. The second connecting part 1352A is arranged at the lower end part of the second telescopic element 1332A in the direction of extension and contraction thereof. The first axle support part 1333 is disposed below the second connecting part 1352A in the extension and contraction direction of the second telescopic element 1332A.
[0184] The first connection part 1351A includes the first upper support part 1331d, the second upper support part 1332d1, and a first connection element 1351a1 which is used to connect the first upper support part 1331d and the second part of top support 1332d1. The second connecting part 1352A includes the first lower support part 1331e, the second lower support part 1332e1 and a second connecting element 1352a1 which is used to connect the first lower support part 1331e and the second lower support part 1332e1. SECOND SHOCK ABSORVER
[0185] Additionally, the outer diameter of a fourth telescopic element 1342A (an example of the second telescopic element according to the present invention) constituting the second damper 1034 is made smaller than the outer diameter of the third telescopic element 1341. More specifically, the length W4 of the fourth inner element 1342b1 (an example of the second inner part according to the present invention) of the fourth telescopic element in the vertical W direction with respect to the second central geometric axis Y2 is made shorter than the length W3 of the third element internal 1341b of the third telescopic element 1341 when the second damper 1034 is viewed from the first front wheel 1031. Similarly, the external diameter of the fourth external element 1342a1 (an example of the second external element in accordance with the present invention) of the fourth element telescopic 1342A is made smaller than that of the first outer element 1341a of the third element t electroscopic 1341. More specifically, the length of the fourth outer element 1342a1 of the fourth telescopic element 1342A in the vertical W direction with respect to the second central geometric axis Y2 is shorter than the length of the third outer element 1341a of the third telescopic element 1341 when the second damper 1034 is viewed from the first front wheel 1031.
[0186] The fourth outer element 1342a1 includes a fourth outer main body 1342c1, a fourth upper support part 1342d1 and a fourth lower support part 1342e1.
[0187] The fourth outer main body 1342c1 allows the fourth inner element 1342b1 to be inserted in the direction of extension and contraction thereof.
[0188] The fourth upper support part 1342d1 and the fourth lower support part 1342e1 are arranged in the extension and contraction direction of the fourth telescopic element 1342A on the side of the fourth outer main body 1342c1.
[0189] The third inner element 1341b and the fourth inner element 1342b1 are connected to each other. The third inner element 1341b and the fourth inner element 1342b1 are connected using a second bracket 1327A. The upper end portion of the third inner element 1341b in the extension and contraction direction thereof and the upper end portion of the fourth inner element 1342b1 in the extension and contraction direction thereof are connected using the second bracket 1327A. The third outer element 1341a and the fourth outer element 1342a1 are connected using a plurality of connecting parts. The third outer element 1341a and the fourth outer element 1342a1 are connected using a third connecting part 1353A (an example of the outer connecting part according to the present invention) and a fourth connecting part 1354A (an example of the part of external connection according to the present invention).
[0190] The third connecting part 1353A and the fourth connecting part 1354A are arranged to be arranged in the extension and contraction direction of the fourth telescopic element 1342A. The third connecting part 1353A is arranged in the middle part of the fourth telescopic element 1342A in the direction of extension and contraction thereof. The fourth connecting part 1354A is arranged at the lower end part of the fourth telescopic element 1342A in the direction of extension and contraction thereof. The second axle support part 1343 is disposed below the fourth connecting part 1354A in the extension and contraction direction of the fourth telescopic element 1342A.
[0191] The third connecting part 1353A includes the third upper support part 1341d, the fourth upper support part 1342d1 and a third connecting element 1353a1 which is used to connect the third upper support part 1341d and the fourth support part top 1342d1. The fourth connecting part 1354A includes the third lower support part 1341e, the fourth lower support part 1342e1, and a fourth connecting element 1354a1 which is used to connect the third lower support part 1341e and the fourth lower support part 1342e1 . ADVANTAGE
[0192] In the modification mentioned above, the upper end portion of the first telescopic element 1331 and the lower end portion of the second telescopic element 1332A are connected using the first support 1317A (an example of the vehicle body support part of according to the present invention), and the second telescopic element 1332A is smaller in diameter than the first telescopic element 1331. Compared to a case in which the first telescopic element 1331 and the second telescopic element 1332A have the same shape, the space (the distance in the direction of arrangement) between the axial center of the first telescopic element 1331 and the axial center of the second telescopic element 1332A can be shortened and the first support 1317A can be reduced in size.
[0193] Similarly, the space (the distance in the direction of arrangement) between the third telescopic element 1341 and the fourth telescopic element 1342 can be shortened and the second support 1327A (an example of the vehicle support part according to present invention) can be reduced in size.
[0194] As a result of this, the increase in the front of vehicle 1001 can be suppressed while the front wheel support structure having the rotation interruption function is obtained using the simple configuration.
[0195] (1) The suspension device (the first shock absorber 1033, the second shock absorber 1034) according to the first embodiment mentioned above is equipped with the first telescopic element (the first telescopic element 1331, the third telescopic element 1341), the second telescopic element (the second telescopic element 1332, the fourth telescopic element 1342, the second telescopic element 1332A, the fourth telescopic element 1342A), the wheel support part (the first axle support part 1333, the support part of second axle 1343) and the vehicle body support part (first support 1317, second support 1327, first support 1317A).
[0196] The first telescopic element (the first telescopic element 1331, the third telescopic element 1341) includes the first outer part (the first outer element 1331a, the third outer element 1341a) and the first inner part (the first inner element 1331b, the third inner element 1341b) of which an end part is inserted into the first outer part (first outer element 1331a, third outer element 1341a). The first telescopic element (the first telescopic element 1331, the third telescopic element 1341) can extend and contract as the first inner part (the first inner element 1331b, the third inner element 1341b) moves with respect to the first eternal part (the first outer element 1331a, third outer element 1341a).
[0197] The second telescopic element (the second telescopic element 1331, the fourth telescopic element 1342, the second telescopic element 1332A, the fourth telescopic element 1342A) includes the second outer part (the second outer element 1332a, the fourth outer element 1342a, the second outer element 1332a1, the fourth outer element 1342a1) connected to the first outer part (the first outer element 1331a, the third outer element 1341a) and the second inner part (the second inner element 1332b, the fourth inner element 1342b, the second inner element 1332b1 the fourth inner element 1342b1) of which an end part is inserted into the second outer part (the second outer element 1332a, the fourth outer element 1342a, the second outer element 1332a1, the fourth outer element 1342a1) and which is connected to the first inner part (first inner element 1331b, third inner element 1341b).
[0198] The second telescopic element (the second telescopic element 1332, the fourth telescopic element 1342, the second telescopic element 1332A, the fourth telescopic element 1342A) can be extended and contracted since the second inner part (the second inner element 1332b, the fourth inner element 1342b, the second inner element 1332b1, the fourth inner element 1342b1) moves with respect to the second outer part (the second outer element 1332a, the fourth outer element 1342a, the second outer element 1332a1, the fourth outer element 1342a1) .
[0199] The wheel support part (the first axle support part 1333, the second axle support part 1343) can support the wheel (the first front wheel 1031, the second front wheel 1032) on the outer element (a first lower part 1033a, second lower part 1034a) including the first everlasting part (first outer element 1331a, third outer element 1341a), the second outer part (second outer element 1332a, fourth outer element 1342a, second element outer 1332a1, the fourth outer element 1342a1) and the outer connecting part (a first outer connecting part 94A, a second outer connecting part 96A) for connecting the first outer part and the second outer part.
[0200] The vehicle body support part (the first support 1317, the second support 1327, and the first support 1317A) can support the internal element in the vehicle body (the vehicle main body 1002) of the vehicle (the vehicle 1001).
[0201] The second outer part (the second outer element 1332a, the fourth outer element 1342a, the second outer element 1332a1, the fourth outer element 1342a1) is formed to be smaller than the first outer part (the first outer element 1331a, the third outer element 1341a) and is connected to the first outer part (the first outer element 1331a, the third outer element 1341a) using the plurality of outer connecting parts (the first connecting part 1351, the second connecting part 1352, the third connecting part 1353, fourth connecting part 1354, first connecting part 1351A, second connecting part 1352A) provided so as to be arranged in the direction of extension and contraction of the second telescopic element (the second telescopic element 1332, fourth telescopic element 1342, second telescopic element 1332A, fourth telescopic element 1342A).
[0202] The second inner part (the second inner element 1332b, the fourth inner element 1342b, the second inner element 1332b1, the fourth inner element 1342b1) is shaped to be equal to or smaller than the first inner part (the first element inner 1331b, the third inner element 1341b). The second inner part (the second inner element 1332b, the fourth inner element 1342b, the second inner element 1332b1, the fourth inner element 1342b1) is connected to the first inner part (the first inner element 1331b, the third inner element 1341b) using by minus one of the internal connecting parts (first support 1317, second support 1327, first support 1317A, second support 1327A).
[0203] The second telescopic element (second telescopic element 1332, fourth telescopic element 1342, second telescopic element 1332A, fourth telescopic element 1342A) is arranged in a position in which the direction of extension and contraction of the second telescopic element ( the second telescopic element 1332, the fourth telescopic element 1342, the second telescopic element 1332A, the fourth telescopic element 1342A) is in parallel with the direction of extension and contraction of the first telescopic element (the first telescopic element 1331, the third telescopic element 1341) ) as seen from the direction of the axis of rotation of the wheel (the first front wheel 1031, the second front wheel 1032) which is supported on the wheel support part (the first axle support part 1333, the support part of the second axis 1343).
[0204] In case the suspension device (the first shock absorber 1033, the second shock absorber 1034) according to the first mode mentioned above is installed in the vehicle (the vehicle 1001), the direction of the geometric axis of rotation of the wheel (a first front wheel 1031, second front wheel 1032) supported on wheel support part (first axle support part 1333, second axle support part 1343) coincides with the left-right direction of the vehicle (the vehicle 1001 ) in the straight state of the vehicle (the vehicle 1001). In this way, the second telescopic element (second telescopic element 1332, fourth telescopic element 1342, second telescopic element 1332A, fourth telescopic element 1342A) is arranged in a position in which the direction of extension and contraction of the second telescopic element (the second telescopic element 1331, fourth telescopic element 1342, second telescopic element 1332A, fourth telescopic element 1342A) is parallel with the direction of extension and contraction of the first telescopic element (first telescopic element 1331, third telescopic element 1341) as seen from the left-right direction of the vehicle (the vehicle 1001) in the straight state of the vehicle in the state of being installed in the vehicle (the vehicle 1001).
[0205] Additionally, the second telescopic element (second telescopic element 1332, fourth telescopic element 1342, second telescopic element 1332A, fourth telescopic element 1342A) is disposed in a position in which the second telescopic element is superimposed with at least part of the first telescopic element (the first telescopic element 1331, the third telescopic element 1341) as viewed from any vertical direction with respect to the geometric axis of rotation of the wheel (the first front wheel 1031, the second wheel front 1032) which is supported on the wheel support part (the first axle support part 1333, the second axle support part 1343).
[0206] The second telescopic element (second telescopic element 1332, fourth telescopic element 1342, second telescopic element 1332A, fourth telescopic element 1342A) is arranged in a position in which the second telescopic element is superimposed on at least part of the first telescopic element (the first telescopic element 1331, the third telescopic element 1341) as seen from the front of the vehicle (the vehicle 1001) in the straight state of the vehicle in the state of being installed in the vehicle (the vehicle 1001).
[0207] With this configuration, the second outer part (second outer element 1332a, fourth eternal element 1342a, second outer element 1332a1, fourth outer element 1342a1) is smaller than the first outer element (first outer element 1331a) , the third outer element 1341a). Additionally, the second inner part (the second inner element 1332b, the fourth inner element 1342b, the second inner element 1332b1, the fourth inner element 1342b1) is equal to or less than the first inner part (the first inner element 1331b, the third inner element 1341b). In this way, the stiffness of the suspension device (the first shock absorber 1033, the second shock absorber 1034) having this configuration may be lower than the stiffness of the suspension device (the first shock absorber 1033, the second shock absorber 1034) equipped with two telescopic elements having the same size.
[0208] However, with this configuration, the second outer part (second outer element 1332a, fourth outer element 1342a, second outer element 1332a1, fourth outer element 1342a1) is smaller than the first outer part (first outer element 1331a, the third outer element 1341a). But the second outer part (the second outer element 1332a, the fourth outer element 1342a, the second outer element 1332a1, the fourth outer element 1342a1) is connected to the first outer part (the first outer element 1331a, the third outer element 1341a) using the plurality of external connecting parts arranged in the extension and contraction direction of the second telescopic element (second telescopic element 1332, fourth telescopic element 1342, second telescopic element 1332A, fourth telescopic element 1342A).
[0209] Additionally, although the second inner part (the second inner element 1332b, the fourth inner element 1342b, the second inner element 1332b1, the fourth inner element 1342b1) is equal to or smaller than the first inner part (the first inner element 1331b, third inner element 1341b), the second inner part is connected to the first inner part (first inner element 1331b, third inner element 1341b) using at least one inner connecting part. As a result, the second telescopic element (second telescopic element 1332, fourth telescopic element 1342, second telescopic element 1332A, fourth telescopic element 1342A) is connected to the first telescopic element (first telescopic element 1331, third telescopic element 1341 ) using at least three positions in the extension-extension direction of contraction of the second telescopic element (second telescopic element 1332, fourth telescopic element 1342, second telescopic element 1332A, fourth telescopic element 1342A).
[0210] Additionally, the second telescopic element (the second telescopic element 1332, the fourth telescopic element 1342, the second telescopic element 1332A, the fourth telescopic element 1342A) is disposed in a position in which the direction of extension and contraction of the second telescopic element (second telescopic element 1332, fourth telescopic element 1342, second telescopic element 1332A, fourth telescopic element 1342A) is parallel with the direction of extension and contraction of the first telescopic element (first telescopic element 1331, the third telescopic element 1341) as seen from the direction of the axis of rotation of the wheel (the first front wheel 1031, the second front wheel 1032) which is supported on the wheel support part (the first axle support part 1333, the second shaft support part 1343).
[0211] In addition, the second telescopic element (second telescopic element 1332, fourth telescopic element 1342, second telescopic element 1332A, fourth telescopic element 1342A) is arranged in a position in which the second telescopic element is superimposed on at least part of the first telescopic element (first telescopic element 1331, third telescopic element 1341) as viewed from any vertical direction with respect to the geometric axis of rotation of the wheel (first front wheel 1031, second front wheel 1032) that is supported on the wheel support part (the first axle support part 1333, the second axle support part 1343).
[0212] Thus, the second telescopic element (the second telescopic element 1332, the fourth telescopic element 1342, the second telescopic element 1332A, the fourth telescopic element 1342A) has the function of preventing the deformation of the first telescopic element (the first element telescopic 1331, third telescopic element 1341) due to the load applied from the road surface to the supported wheel (first front wheel 1031, second front wheel 1032), the so-called splint function. As a result, the suspension device (first damper 1033, second damper 1034) can ensure sufficient rigidity to support the load applied from the road surface to the supported wheel (first front wheel 1031, second front wheel 1032).
[0213] With this configuration, the second outer part (the second outer element 1332a, the fourth outer element 1342a, the second outer element 1332a1, the fourth outer element 1342a1) is smaller than the first outer part (the first outer element 1331a , the third outer element 1341a). Additionally, the second inner part (the second inner element 1332b, the fourth inner element 1342b, the second inner element 1332b1, the fourth inner element 1342b1) is equal to or smaller than the first inner part (the first inner element 1331b, the third element internal 1341b).
[0214] Thus, in case the suspension device (the first shock absorber 1033, the second shock absorber 1034) according to the first mode mentioned above is installed in the vehicle (the vehicle 1001), the interference of two telescopic elements (the third telescopic element 1341, fourth telescopic element 1342, fourth telescopic element 1342A) of the right suspension device (the second shock absorber 1034) with the left front wheel (the first front wheel 1031) or the two telescopic elements (the first telescopic element 1331 , the second telescopic element 1332, the second telescopic element 1332A) of the left suspension device (the first damper 1033) can be easily avoided.
[0215] Similarly, the interference of two telescopic elements (the first telescopic element 1331, the second telescopic element 1332, the second telescopic element 1332A) of the left suspension device (the first shock absorber 1033) with the right front wheel (a second front wheel 1032) or two telescopic elements (the third telescopic element 1341, the fourth telescopic element 1342, the fourth telescopic element 1342A) of the right suspension device (the second shock absorber 1034) can be easily avoided. As a result, the vehicle (vehicle 1001) equipped with the suspension device may be reduced in size.
[0216] With this configuration, the vehicle (vehicle 1001) equipped with the suspension device can be reduced in size while ensuring sufficient rigidity to support the load applied from the road surface to the supported wheel (the first front wheel 1031 , the second front wheel 1032).
[0217] Note that, the wheel support part (the first axle support part 1333, the second axle support part 1343) may be able to support the wheel (the first front wheel 1031, the second wheel front 1032) on the inner element (the first upper part 1033b, the second upper part 1034b) including the first and second inner parts (the second inner element 1332b, the fourth inner element 1342b, the second inner element 1332b1, the fourth inner element 1342b1 ) connected to each other. The vehicle body support part (the first support 1317, the second support 1327 and the first support 1317A) may be able to support the outer member (the first lower part 1033a, the second lower part 1034a) in the vehicle body ( the main body of the vehicle 1002) of the vehicle (the vehicle 1001). Furthermore, in that case, the advantage mentioned above can be obtained.
[0218] (2) The suspension device (the first damper 1033, the second damper 1034) acting with the first mode mentioned above additionally has the following configuration.
[0219] The second outer part (the second outer element 1332a, the fourth outer element 1342a, the second outer element 1332a1, the fourth outer element 1342a1) is made shorter than the first outer part (the first outer element 1331a, the third outer element 1341a) in the extension and contraction direction of the second telescopic element (the second telescopic element 1332, the fourth telescopic element 1342, the second telescopic element 1332A, the fourth telescopic element 1342A) in the extension and contraction direction of the second telescopic element (second telescopic element 1332, fourth telescopic element 1342, second telescopic element 1332A, fourth telescopic element 1342A), and is connected to the first outer part (first outer element 1331a, third outer element 1341a) using the plurality of external connecting parts arranged in the extension and contraction direction of the second telescopic element (the second telescopic element 1 332, fourth telescopic element 1342, second telescopic element 1332A, fourth telescopic element 1342A).
[0220] Since the inner element is inserted into the outer element, the outer element is larger than the inner element. With this configuration (2), since the second external part (the second external element 1332a, the fourth external element 1342a, the second external element 1332a1, the fourth external element 1342a1), being larger among the second telescopic elements (the second telescopic element 1332, the fourth telescopic element 1342, the second telescopic element 1332A, the fourth telescopic element 1342A) is shortened, the second telescopic element (the second telescopic element 1332, the fourth telescopic element 1342, the second telescopic element 1332A, the fourth telescopic element 1342A) can be made shorter than the first telescopic element (first telescopic element 1331, third telescopic element 1341).
[0221] Additionally, since the second outer part (the second outer element 1332a, the fourth outer element 1342a, the second outer element 1332a1, the fourth eternal element 1342a1) is connected to the first outer part (the first outer element 1331a and the third external element 1341a) using the plurality of external connecting parts arranged in the extension and contraction direction of the second telescopic element (the second telescopic element 1331, the fourth telescopic element 1342, the second telescopic element 1332A, the fourth telescopic element 1342A), the reduction in stiffness can be suppressed. Thus, in case the suspension device (the first shock absorber 1033, the second shock absorber 1034) according to the first mode mentioned above is installed in the vehicle (the vehicle 1001), the interface of the two telescopic elements (the third telescopic element 1341, the fourth telescopic element 1342, the fourth telescopic element 1342A) of the right suspension device (the second shock absorber 1034) with the left front wheel (the first front wheel 1031) or those of the telescopic elements (the first telescopic element 1331, the second telescopic element 1332, second telescopic element 1332A) of the left suspension device (first shock absorber 1033) can be easily avoided.
[0222] Similarly, the interference of the two telescopic elements (the first telescopic element 1331, the second telescopic element 1332, the second telescopic element 1332A) of the left suspension device (the first shock absorber 1033) with the right front wheel (a second front wheel 1032) or the two telescopic elements (third telescopic element 1341, fourth telescopic element 1342, fourth telescopic element 1342A) can be easily avoided. In this way, the vehicle (the vehicle 1001) equipped with the suspension device can be further reduced in size. As a result, with this configuration, the vehicle (vehicle 1001) equipped with the suspension device can be reduced in size while ensuring sufficient rigidity to support the load applied from the road surface to the supported wheel (the first front wheel 1031, the second front wheel 1032).
[0223] (3) The suspension device (the first damper 1033, the second damper 1034) according to the first embodiment mentioned above additionally has the following configuration.
[0224] The second telescopic element (the second telescopic element 1332, the fourth telescopic element 1342, the second telescopic element 1332A, and the fourth telescopic element 1342A) is shorter than the first telescopic elements (the first telescopic element 1331, the third telescopic element 1341). The first telescopic element (the first telescopic element 1331, the third telescopic element 1341) is equipped with the component support part (the first sensor support 1814, the second sensor support 1824) capable of supporting the components (the first sensor of wheel speed 1081, the second wheel speed sensor 1082) in the concave portion formed using the first telescopic element (the first telescopic element 1331, the third telescopic element 1341) and the second telescopic element (the second telescopic element 1332, fourth telescopic element 1342, second telescopic element 1332A, fourth telescopic element 1342A) as seen from the direction of the geometric axis of rotation of the wheel (first front wheel 1031, second front wheel 1032) supported on the part. wheel support (the first axle support part 1333, the second axle support part 1343).
[0225] Typically, the component support part capable of supporting the components installed in the vehicle (the vehicle 1001) is provided around the first telescopic element (the first telescopic element 1331, the third telescopic element 1341) and the second telescopic element ( the second telescopic element 1332, the fourth telescopic element 1342, the second telescopic element 1332A, the fourth telescopic element 1342A). With this configuration (3), since the second outer part (the second outer element 1332a, the fourth outer element 1342a, the second outer element 1332a1, the fourth outer element 1342a1) is made shorter than the first outer part (the first outer element 1331a, third outer element 1341a) in the direction of extension and contraction of the second telescopic element (second telescopic element 1332, fourth telescopic element 1342, second telescopic element 1332A, fourth telescopic element 1342A), the The lower end of the second outer part (the second outer member 1332a, the fourth outer member 1342a, the second outer member 1332a1, the fourth outer member 1342a1) is positioned above the lower end of the first outer part (the first outer member 1331a, the third external element 1341a) in the direction of extension and contraction of the second telescopic element (the second telescopic element 1332, the fourth telescopic element 1342, second telescopic element 1332A, fourth telescopic element 1342A). In this way, the concave part is formed using the first telescopic elements (the first telescopic element 1331, the third telescopic element 1341) and the second telescopic elements (the second telescopic element 1332, the fourth telescopic element 1342 the second telescopic element 1332A , and the fourth telescopic element 1342A). The component support part capable of supporting the components installed in the vehicle (the vehicle 1001) is provided in the concave part. For this reason, the suspension device (first damper 1033, second damper 1034) can be reduced in size. Thus, in case the suspension device (the first shock absorber 1033, the second shock absorber 1034) according to the first modality mentioned above is installed in the vehicle (the vehicle 1001), the interference of the two telescopic elements (the third telescopic element 1341, the fourth telescopic element 1342, the fourth telescopic element 1342A) of the right suspension device (the second shock absorber 1034) with the left front wheel (the first front wheel 1031) or the two telescopic elements (the first telescopic element 1331, the second telescopic element 1332, second telescopic element 1332A) of the left suspension device (first shock absorber 1033) can be easily avoided. Similarly, the interference of two telescopic elements (the first telescopic element 1331, the second telescopic element 1332, the second telescopic element 1332A) of the left suspension device (the first shock absorber 1033) with the right front wheel (the second front wheel 1032) or the two telescopic elements, (the third telescopic element 1341, the fourth telescopic element 1342, the fourth telescopic element 1342A) of the right suspension device (the second shock absorber 1034) can be easily avoided. In this way, the vehicle (the vehicle 1001) equipped with the suspension device can be further reduced in size. As a result, with this configuration, the vehicle (the vehicle 1001) equipped with the suspension device can be reduced in size while ensuring sufficient rigidity to support the load applied from the road surface to the supported wheels (the first front wheel 1031, the second front wheel 1032).
[0226] Note that, the component support part can be provided in the second telescopic element (the second telescopic element 1332, the fourth telescopic element 1342, the second telescopic element 1332A, and the fourth telescopic element 1342A).
[0227] Also, in this case, the advantage mentioned above can be obtained.
[0228] (4) The suspension device (the first damper 1033, the second damper 1034) according to the first embodiment mentioned above additionally has the following configuration. The concave part 1361 is provided in the outer element (first lower part 1033a, second lower part 1034a).
[0229] With this configuration (4), the concave part is easily formed using the first telescopic element (the first telescopic element 1331, the third telescopic element 1341) and the second telescopic element (the second telescopic element 1332, the fourth telescopic element 1342, second telescopic element 1332A, fourth telescopic element 1342A) which is shorter than the first telescopic element (first telescopic element 1331, third telescopic element 1341). Additionally, since the first eternal part (the first outer element 1331a, the third outer element 1341a) and the second outer part (the second outer element 1332a, the fourth outer element 1342a, the second outer element 1332a1, the fourth outer element 1342a1 ) are connected using the plurality of external connecting parts, the rigidity of the external element is high. Since the concave part is provided in the outer element having high rigidity, the concave part can be formed with a simple structure. For this reason, the suspension device (first damper 1033, second damper 1034) can be reduced in size. Thus in case the suspension device (the first shock absorber 1033, the second shock absorber 1034) according to the present invention is installed in the vehicle, the interference of the two telescopic elements of the left suspension device can be easily avoided. Similarly, interference of the two telescopic elements of the left suspension device with the right front wheel or the two telescopic elements of the right suspension device can be easily avoided. As a result, the vehicle equipped with the suspension device may be further reduced in size. Thus, with this configuration, the vehicle equipped with the suspension device can be reduced in size while ensuring sufficient rigidity to support the load applied from the road surface to the supported wheel.
[0230] (5) The suspension device (the first damper 1033, the second damper 1034) according to the first embodiment mentioned above additionally has the following configuration. The inner connecting part (the first support 1317, the second support 1327, the first support 1317A, the second support 1327A) connects the other end part of the first inner part (the first inner element 1331b, the third inner element 1341b) to the another end part of the second inner part (second inner element 1332b, fourth inner element 1342b, second inner element 1332b1, fourth inner element 1342b1).
[0231] With this configuration (5), since the interconnecting part (the first support 1317, the second support 1327, the first support 1317A, the second support 1327A) connects to another end part of the first inner part (the first inner element 1331b, the third inner element 1341b) to the other end part of the second inner part (the second inner element 1332b, the fourth inner element 1342b, the second inner element 1332b1, the fourth inner element 1342b1), the concave part is formed on an end side of the second telescopic element (the second telescopic element 1332, the fourth telescopic element 1342, the second telescopic element 1332A, the fourth telescopic element 1342A) which is shorter than the first telescopic element (the first telescopic element 1331 , the third telescopic element 1341). Since the component support part can be formed using the concave part, the space can be efficiently utilized, and the suspension device (first damper 1033, second damper 1034) can be reduced in size. Thus, in case the suspension device (the first shock absorber 1033, the second shock absorber 1034) according to the present invention is installed in the vehicle, the interference of the two telescopic elements of the right suspension device with the left front wheel or two Telescopic elements of the left suspension device can be easily avoided. Similarly, interference of the two telescopic elements of the left suspension device with the right front wheel or the two telescopic elements of the right suspension device can be easily avoided. As a result, the vehicle equipped with the suspension device may be further reduced in size. Thus, with this configuration, the vehicle equipped with the suspension device can be reduced in size while ensuring sufficient rigidity to support the load applied from the road surface to the supported wheels.
[0232] (6) The suspension device (the first damper 1033, the second damper 1034) according to the first embodiment mentioned above has the following configuration. The wheel support part (the first axle support part 1333, the second axle support part 1343) is provided on the outer member (the first lower part 1033a, the second lower part 1034a). The vehicle body support part (the first support 1317, the second support 1327, and the first support 1317A) is provided on the inner element.
[0233] With this configuration (6), since the first external part (the first external element 1331a, the third external element 1341a) and the second external part (the second external element 1332a, the fourth external element 1342a, the second element external 1332a1, the fourth external element 1342a1) are connected using the plurality of external connecting parts, the rigidity of the external element (first lower part 1033a, second lower part 1034a) is high. Since the wheel support part (the first axle support part 1333, the second axle support part 1343) is provided in the outer member (the first lower part 1033a, the second lower part 1034a) having high rigidity, the wheel support part (first axle support part 1333, second axle support part 1343) can be formed with a simple structure. For this reason, the suspension device (first damper 1033, second damper 1034) can be reduced in size. Thus, in case the suspension device (the first shock absorber 1033, the second shock absorber 1034) according to the first mode mentioned above is installed in the vehicle (the vehicle 1001), the interference of the two telescopic elements (the third telescopic element 1341, the fourth telescopic element 1342, the fourth telescopic element 1342A) of the right suspension device (the second shock absorber 1034) with the left front wheel (the first front wheel 1031) or the two telescopic elements (the first telescopic element 1331, the second telescopic element 1332, second telescopic element 1332A) of the left suspension device (first shock absorber 1033) can be easily avoided. Similarly, the interference of the two telescopic elements (the first telescopic element 1331, the second telescopic element 1332, the second telescopic element 1332A) of the left suspension device (the first shock absorber 1033) with the right front wheel (the second front wheel 1032) or the two telescopic elements (the third telescopic element 1341, the fourth telescopic element 1342, the fourth telescopic element 1342A) of the right suspension device (the second shock absorber 1034) can be easily avoided. In this way, the vehicle equipped with the suspension device can be further reduced in size. As a result, with this configuration, the vehicle (the vehicle 1001) equipped with the suspension device can be reduced in size while ensuring sufficient rigidity to support the load applied from the road surface to the supported wheel (the first front wheel 1031, the second front wheel 1032).
[0234] This configuration (6) is preferably combined with the configuration mentioned above (3). The suspension device (first damper 1033, second damper 1034) can be reduced in size by providing the wheel support part (first axle support part 1333, second axle support part 1343) in the concave part formed by the first telescopic element (the first telescopic element 1331, the third telescopic element 1341) and the second telescopic element (the second telescopic element 1332A, the fourth telescopic element 1342A). Thus, in case the suspension device (the first shock absorber 1033, the second shock absorber 1034) according to the present invention is installed in the vehicle (the vehicle 1001), the interference of the two telescopic elements (the third telescopic element 1341, the fourth to-telescopic element 1342, the fourth telescopic element 1342A) of the right suspension device (the second shock absorber 1034) with the left front wheel (the first front wheel 1031) or the two telescopic elements (the first telescopic element 1331, the second telescopic element 1332, the second telescopic element 1332A) of the left suspension device (the first shock absorber 1033) can be easily avoided. Similarly, the interference of the two telescopic elements (the first telescopic element 1331, the second telescopic element 1332, the second telescopic element 1332A) of the left suspension device (the first shock absorber 1033) with the right front wheel (the second front wheel 1032) or the two telescopic elements (the third telescopic element 1341, the fourth telescopic element 1342, the fourth telescopic element 1342A) of the right suspension device (the second shock absorber 1034) can be easily avoided. In this way, the vehicle (the vehicle 1001) equipped with the suspension device can be further reduced in size. As a result, with this configuration, the vehicle (the vehicle 1001) equipped with the suspension device can be reduced in size while ensuring sufficient rigidity to support the load applied from the road surface to the supported wheel (the first wheel front 1031, the second front wheel 1032).
[0235] (7) The suspension device (the first damper 1033, the second damper 1034) according to the first embodiment mentioned above additionally has the following configuration. The vehicle body support part (the first support 1317, the second support 1327, and the first support 1317A) is provided in the internal connecting part.
[0236] With this configuration (7), since the vehicle body support part (the first support 1317, the second support 1327, the first support 1317A) is provided in the internal connection part, the distance between the first part inner (first inner element 1331b, third inner element 1341b) and the second inner part (second inner element 1332b, fourth inner element 1342b, second inner element 1332b1, fourth inner element 1342b1) can be reduced. For this reason, the suspension device (first damper 1033, second damper 1034) can be reduced in size. Thus, in case the suspension device (the first shock absorber 1033, the second shock absorber 1034) according to the first modality mentioned above is installed in the vehicle (the vehicle 1001), the interference of the two telescopic elements (the third telescopic element 1341, the fourth telescopic element 1342, the fourth telescopic element 1342A) of the right suspension device (the second shock absorber 1034) with the left front wheel (the first front wheel 1031) or the two telescopic elements (the first telescopic element 1331, the second telescopic element 1332, second telescopic element 1332A) of the left suspension device (first shock absorber 1033) can be easily avoided. Similarly, the interference of the two telescopic elements (first telescopic element 1331, second telescopic element 1332, second telescopic element 1332A) of the left suspension device (first shock absorber 1033) with the right front wheel (second front wheel 1032 ) or the two telescopic elements (the third telescopic element 1341, the fourth telescopic element 1342, the fourth telescopic element 1342A) of the right suspension device (the second shock absorber 1034) can be easily avoided. In this way, the vehicle (the vehicle 1001) equipped with the suspension device can be further reduced in size. As a result, with this configuration, the vehicle (the vehicle 1001) equipped with the suspension device can be reduced in size while ensuring sufficient rigidity to support the load applied from the road surface to the supported wheel (the first front wheel 1031, the second front wheel 1032).
[0237] (8) The suspension devices (the first damper 1033, the second damper 1034) according to the above-mentioned first embodiment can additionally have the following configuration instead of the above-mentioned configuration (6). The vehicle body support part is provided in the outer element.
[0238] One end of the inner part is inserted into the outer part. In this way, the inner part is smaller than the outer element in the vertical direction with respect to the extension and contraction direction of the telescopic element. With this configuration (8), the wheel support part (the first axle support part 1333, the second axle support part 1343) is provided in the inner element including the inner part smaller than the outer part. Additionally, the larger outer portion is disposed away from the wheel (first front wheel 1031, second front wheel 1032). For this reason, the suspension device can be reduced in size. Thus, in case the suspension device is installed on the vehicle (the vehicle 1001), the interference of the two telescopic elements of the right suspension device with the left front wheel (the first front wheel 1031) or the two telescopic elements of the device left suspension can be easily avoided. Similarly, interference of the two telescopic elements of the left suspension device with the right front wheel (second front wheel 1032) or the two telescopic elements of the right suspension device can be easily avoided. In this way, the vehicle (the vehicle 1001) equipped with the suspension device can be further reduced in size. As a result, with this configuration, the vehicle (the vehicle 1001) equipped with the suspension device can be reduced in size while ensuring sufficient rigidity to support the load applied from the road surface to the supported wheel (the first front wheel 1031, the second front wheel 1032).
[0239] (9) The suspension device (the first damper 1033, the second damper 1034) according to the first embodiment mentioned above can additionally have the following configuration. The vehicle body support part is provided in the first outer part.
[0240] With this setting (9), the vehicle body support part is configured using the first outer part which is larger than the second outer part. For this reason, the suspension device can be reduced in size. Thus, in case the suspension device is installed on the vehicle (the vehicle 1001), the interference of the two telescopic elements of the right suspension device with the left front wheel (the first front wheel 1031) or the two telescopic elements of the device left suspension can be easily avoided. Similarly, interference of the two telescopic elements of the left suspension device with the right front wheel (second front wheel 1032) or the two telescopic elements of the right suspension device can be easily avoided. In this way, the vehicle (the vehicle 1001) equipped with the suspension device can be further reduced in size. As a result, with this configuration, the vehicle (the vehicle 1001) equipped with the suspension device can be reduced in size while ensuring sufficient rigidity to support the loads applied from the road surface to the supported wheel (the first wheel front 1031, the second front wheel 1032).
[0241] (10) The suspension device (the first damper 1033, the second damper 1034) according to the first embodiment mentioned above additionally has the following configuration. The inner connecting part connects the other end part of the first inner part (the first inner element 1331b, the third inner element 1341b) to the other end part of the second inner part (the second inner element 1332b, the fourth inner element 1342b, the second inner element 1332b1, the fourth inner element 1342b1) in the same position as the second telescopic element (the second telescopic element 1332, the fourth telescopic element 1342, the second telescopic element 1332A, the fourth telescopic element 1342A) in the directions of extension and contraction.
[0242] The inner connecting part includes the upper end part of the first inner part (the first inner element 1331b, the third inner element 1341b) and the upper end part of the second inner part (the second inner element 1332b, the fourth inner element 1342b, second inner element 1332b1, fourth inner element 1342b1) in an imaginary vertical plane with respect to the direction of extension/contraction of the second telescopic element (the second telescopic element 1332, the fourth telescopic element 1342, the second telescopic element 1332A, the fourth telescopic element 1342A).
[0243] With this setting (10), the inner connection part can be made small. For this reason, the suspension device (first damper 1033, second damper 1034) can be reduced in size. Thus, in case the suspension device (the first shock absorber 1033, the second shock absorber 1034) according to the first modality mentioned above is installed in the vehicle (the vehicle 1001), the interference of the two telescopic elements (the third telescopic element 1341, the fourth telescopic element 1342, the fourth telescopic element 1342A) of the right suspension device (the second shock absorber 1034) with the left front wheel (the first front wheel 1031) or the two telescopic elements (the first telescopic element 1331, the second telescopic element 1332, second telescopic element 1332A) of the left suspension device (first shock absorber 1033) can be easily avoided. Similarly, the interference of the two telescopic elements (first telescopic element 1331, second telescopic element 1332, second telescopic element 1332A) of the left suspension device (first shock absorber 1033) with the right front wheel (second front wheel 1032 ) or the two telescopic elements (the third telescopic element 1341, the fourth telescopic element 1342, the fourth telescopic element 1342A) of the right suspension device (the second shock absorber 1034) can be easily avoided. In this way, the vehicle (the vehicle 1001) equipped with the suspension device can be further reduced in size. As a result, with this configuration, the vehicle (the vehicle 1001) equipped with the suspension device can be reduced in size while ensuring sufficient rigidity to support the load applied from the road surface to the supported wheel (the first front wheel 1031, the second front wheel 1032).
[0244] This configuration (10) is preferably combined with the configurations mentioned above from (3) to (9). With this configuration (10), the concave part is formed using the first telescopic element (the first telescopic element 1331, the third telescopic element 1341) and the second telescopic element (the second telescopic element 1332, the fourth telescopic element 1342, the second telescopic element 1332A, fourth telescopic element 1342A) can be increased. For this reason, the suspension device (first damper 1033, second damper 1034) can be reduced in size. Thus, in case the suspension device (the first shock absorber 1033, the second shock absorber 1034) according to the first modality mentioned above is installed in the vehicle (the vehicle 1001), the interference of the two telescopic elements (the third telescopic element 1341, the fourth telescopic element 1342, the fourth telescopic element 1342A) of the right suspension device (the second shock absorber 1034) with the left front wheel (the first front wheel 1031) or the two telescopic elements (the first telescopic element 1331, the second telescopic element 1332, second telescopic element 1332A) of the left suspension device (first shock absorber 1033) can be easily avoided. Similarly, the interference of the two telescopic elements (the first telescopic element 1331, the second telescopic element 1332, the second telescopic element 1332A) of the left suspension device (the first shock absorber 1033) with the right front wheel (the second wheel front 1032) or the two telescopic elements (the third telescopic element 1341, the fourth telescopic element 1342, the fourth telescopic element 1342A) of the right suspension device (the second shock absorber 1034) can be easily avoided. In this way, the vehicle (the vehicle 1001) equipped with the suspension device can be further reduced in size. As a result, with this configuration, the vehicle (the vehicle 1001) equipped with the suspension devices can be reduced in size while ensuring sufficient rigidity to support the load applied from the road surface to the supported wheel (the first front wheel 1031, the second front wheel 1032).
[0245] (11) The suspension device (the first damper 1033 the second damper 1034) according to the first mode mentioned above can additionally have the following configuration. The second inner part (the second inner element 13322b1, the fourth inner element 1342b1) is formed to be smaller than the first inner part (the first inner element 1331b, the third inner element 1341b) in the vertical direction with respect to the extension direction and contracting the second telescopic element (the second telescopic element 1332A, the fourth telescopic element 1342A) as seen from the direction of the axis of rotation of the wheel supported on the wheel support part (the first axle support part 1333, a second axle support part 1343). Additionally, the second inner part (the second inner element 1332b1, the fourth inner element 1342b1) is formed to be smaller than the first inner part (the first inner element 1331b, the third inner element 1341b) in the vertical direction with respect to the direction of extension and contraction of the second telescopic element (the second telescopic element 1332A, the fourth telescopic element 1342A) as viewed from any vertical direction with respect to the geometric axis of rotation of the wheel (the first front wheel 1031, the second front wheel 1032 ) supported on the wheel support part (the first axle support part 1333, the second axle support part 1343).
[0246] With this configuration (11), the second inner part (the second inner element 1332b1, the fourth inner element 1342b1) is formed to be small in the direction of extension and contraction of the second telescopic element (the second telescopic element 1332A, the fourth telescopic element 1342A). In this way, the second outer part (the second outer element 1332a1, the fourth outer element 1342a1) can also be made small in the vertical direction with respect to the direction of extension and contraction of the second telescopic element (the second telescopic element 1332A, the fourth element telescopic 1342A). Additionally, the internal connecting part can also be made small. For this reason, the suspension device (first damper 1033, second damper 1034) can be reduced in size. Thus, in case the suspension device (the first shock absorber 1033, the second shock absorber 1034) according to the first mode mentioned above is installed in the vehicle (the vehicle 1001), the interference of the two telescopic elements (the third telescopic element 1341 , the fourth telescopic element 1342A) of the right suspension device (the second shock absorber 1034) with the left front wheel (the first front wheel 1031) or the two telescopic elements (the first telescopic element 1311, the second telescopic element 1332A) of the device left suspension (the first shock absorber 1033) can be easily avoided. Similarly, the interference of the two telescopic elements (the first telescopic element 1331, the second telescopic element 1332A) of the left suspension device (the first shock absorber 1033) with the right front wheel (the second front wheel 1032) or the two elements telescopic elements (the third telescopic element 1341, the fourth telescopic element 1342A) of the right suspension device (the second shock absorber 1034) can be easily avoided. In this way, the vehicle (the vehicle 1001) equipped with the suspension device can be further reduced in size. As a result, with this configuration, the vehicle (the vehicle 1001) equipped with the suspension device can be reduced in size while ensuring sufficient rigidity to support the load applied from the road surface to the supported wheel (the first front wheel 1031, the second front wheel 1032).
[0247] In the first embodiment mentioned above, although the upper parts of the first telescopic element 1331 and the second telescopic element 1332 are internal elements and the lower parts are external elements, the elements are not limited to this example. The upper parts of the first telescopic element 1331 and the second telescopic element 1332 can be the outer elements and the lower parts can be the inner elements. Similarly, the upper parts of the third telescopic element 1341 and the fourth telescopic element 1342 can be the outer elements and the lower parts can be the inner elements.
[0248] Additionally, in the first embodiment mentioned above, although the second telescopic element 1332 is arranged in front of the first telescopic element 1331, the arrangement is not limited to this example. The first telescopic element 1331 and the second telescopic element 1332 need only be arranged on the same side as the first front wheel 1031; for example, the second telescopic element 1332 may be disposed behind the first telescopic element 1331. Similarly, the third telescopic element 1341 and the fourth telescopic element 1342 need only be disposed on the same side as the second front wheel 1032; for example, fourth telescopic element 1342 may be disposed behind third telescopic element 1341.
[0249] Additionally, in the above-mentioned first embodiment, the first damper 1033 and the second damper 1034 are disposed between the first front wheel 1031 and the second front wheel 1032 in the left-right direction of the vehicle. However, the first damper 1033 may be disposed further out from the vehicle than the first front wheel 1031 in the left-right direction of the vehicle; similarly, the second damper 1034 may be disposed further out from the vehicle than the second front wheel 1032 in the left-right direction of the vehicle.
[0250] Furthermore, in the first mode mentioned above, although an example in which the first telescopic element 1331 has a damping function and the second telescopic element 1332 does not have any damping function has been described, the configuration is not limited to this example. For example, both the first telescopic element 1331 and the second telescopic element 1332 can have a damping function. Similarly, both the third telescopic element 1341 and the fourth telescopic element 1342 may have a damping function.
[0251] Additionally still, in the first mode mentioned above, the direction of extension and contraction of the first telescopic element 1331 and the direction of extension and contraction of the second telescopic element 1332 are in parallel with the direction of the first central geometric axis Y1. However, the extension and contraction direction of the first telescopic element 1331 and the extension and contraction direction of the second telescopic element 1332 may not be parallel to the direction of the first central geometric axis Y1. Similarly, in the first embodiment mentioned above, the extension and contraction direction of the third telescopic element 1341 and the extension and contraction direction of the fourth telescopic element 1341 and the extension and contraction direction of the fourth telescopic element 1342 are parallel to the direction of the second central geometric axis Y2. However, the extension and contraction direction of the third telescopic element 1341 and the extension and contraction direction of the fourth telescopic element 1342 may not be parallel to the direction of the second central geometric axis Y2.

The first support 335 is supported on the first lateral support element 53 so as to be rotatable about the second geometric axis of rotation 312. The first lateral support element 53A is secured to the first bracket 335 so as not to move in an up-down direction with respect thereto.
[0282] The first axis of rotation 311 supported at the lower end of the first damper 33 is positioned closer to the axis 33a of the first damper 33 than the axis 82a of the first rod element 82 in a side view.
[0283] Figure 14 is an exploded perspective view illustrating a state in which the first damper mechanism 35 is disassembled. In figure 14, the first front wheel 31 is not illustrated. The second guide cylinder 812 of the first guide 81 directs the direction of movement of the first rod element 82. The second guide cylinder 812 does not grip the first rod element 82. In this way, the first rod element 82 is provided so as to move with respect to the second guide cylinder 812 in the direction of extension of the first rod element 82.
[0284] The first bracket 335 includes a first punch hole 335b, a second punch hole 335c, a first set screw 335d, and a second set screw 335e. The first rod element 82 is inserted into the first bore hole 335b. A large diameter portion 821 is provided at one end of the first shank element 82. The large diameter portion 821 is larger than the other portion of the first shank element 82 in diameter. The first bore hole 335b is smaller than the large diameter portion 821 in diameter. The first inner tube 332 is inserted into the second bore hole 335c. The first set screw 335d is disposed close to the first hollow hole 335b. The first adjustment screw 335d is used to adjust the diameter of the first hollow hole 335b. The second set screw 335e is disposed near the second bore hole 335c. The second set screw 335e is used to adjust the diameter of the second hollow hole 335c.
[0285] The first snubber mechanism 35 is mounted as described below. The second set screw 335e is adjusted to allow the diameter of the second bore hole 335c to become larger, and the first inner tube 332 is inserted into the second bore hole 335c from the underside to the top side of the second bore hole 335c. Then the second adjustment screw 335e is adjusted. The first shank element 82 is inserted into the first bore hole 335b from the top side to the bottom side of the first bore hole 335b. Then, the first set screw 335d is adjusted, and the first rod element 82 is secured to the first support 335. In that state, when the first inner tube 332 is further inserted into the first outer tube 331, the first support 335 and the first rod element 82 are moved downwardly in accordance with insertion of the first inner tube 332. REFERENCE EXAMPLE FEATURES
[0286] The characteristics of the reference example will be described below.
[0287] In the reference example, the first damper mechanism 35 prevents the relative rotation of the first outer tube 331 and the first inner tube 332. In other words, the first damper mechanism 35 prevents the first outer tube 331 from rotating around the center of the first inner tube 332.
[0288] When the first outer tube 331 is about to rotate with respect to the first inner tube 332, the first rod element 82 rotates around the center of the first damper 33 by the first guide 81 which is secured to the first outer tube 331. Since the first rod element 82 is connected to the first inner tube 332 through the first support 335, the first rod element 82 cannot rotate around the center of the first damper 33 unless the first support 335 rotates. This is also applicable to the second damper mechanism 36.
[0289] In the three-wheeled vehicle mentioned above 1, the first rod element 82 is lighter than the first shock absorber 33. For this reason, the weight of the vehicle can be reduced more than in the case of the weight of the first element of stem 82 is equal to or greater than that of the first shock absorber 33.
[0290] In the above-mentioned three-wheeled vehicle 1, the first rod element 82 is shorter than the first damper 33. For example, in the case of a configuration in which a rod element having the same length as the first damper 33 is used instead of the first rod element 82 to support the first front wheel 31 together with the first damper 33, the following problem will occur. The damper can extend and contract in the damper extension direction. In case the installation accuracy of the shock absorber and the rod element to support the first front wheel 31 is low, for example in case the distance between the lower end of the shock absorber and the lower end of the rod element is greater than the distance between the upper end of the damper and the upper end of the rod element, the damper can be tilted with respect to the vertical direction. In this case, the shock absorber presents difficulties in extension and contraction and has low impact absorption. Therefore, in the configuration in which the damper and the stem element are of the same length, the damper and the stem element must be arranged precisely in parallel with each other. However, if the length of the rod element is longer, it is difficult to arrange the rod element in parallel with the damper. In the above-mentioned three-wheeled vehicle 1, since the first rod element 82 is shorter than the first damper 33, the first damper 33 and the first rod element 82 are easily arranged in parallel with each other.
[0291] In the three-wheeled vehicle 1, the first rod element 82 is shorter than the first damper 33. For that reason, a space is provided below the first rod element 82. In the three-wheeled vehicle 1, the first brake device 337 is disposed in this space. As a result, the configuration around the first front wheel 3 and the first shock absorber 33 becomes compact.
[0292] When the first shank element 82 is installed in the first bracket 335, the first shank element 82 is inserted into the first bore hole 335b from the upper side to the underside of the first bore hole 335b, and the first bore screw fit 335d is fitted, where the first rod element 82 can be installed on the first bracket 335. With this configuration, mounting is facilitated. SECOND MODE
[0293] A second embodiment of the suspension device according to preferred embodiments of the present invention will be described below with reference to figures 15 and 16.
[0294] A third damping mechanism 9 according to the second embodiment can be installed in the three-wheeled vehicle 1 described in the reference example mentioned above, instead of in the first damping mechanism 35 and second damping mechanism 36.
[0295] Figure 15 illustrates the third damping mechanism 9 (an example of the suspension device according to the present invention) according to the second embodiment.

The first spinning plate 913 and the second clamping plate 914 are arranged to be disposed in the extension and contraction direction of the third damper 91 on the side of the main body of third outer tube 911a. First clamping plate 913 and second clamping plate 914 are each provided with a mounting hole. The first clamp plate 913 and the second clamp plate 914 extend from the third outer tube 911 to the fourth buffer 92. The first clamp plate 913 is positioned above the second clamp plate 914. The fourth buffer 92 (a example of the second telescopic element according to the present invention) includes a fourth outer tube 921 (an example of the second outer part according to the present invention) and a fourth inner tube 922 (an example of the second inner part according to the present invention). invention).
[0297] The fourth damper 92 is the so-called telescopic damper. The lower end portion of the fourth inner tube 922 is inserted into the fourth outer tube 921. The fourth inner tube 922 is movable with respect to the fourth outer tube 921 in the direction of extension and contraction thereof. The fourth shock absorber 92 is lighter than the third shock absorber 91. The fourth shock absorber 92 is shorter than the third shock absorber 91. The fourth shock absorber 92 is shorter than the third shock absorber 91 in the direction of extension and contraction of the shock. The fourth outer tube 921 is shorter than the third outer tube 911 in the direction of extension and contraction thereof.
[0298] The upper part of the fourth inner tube 922 is secured to the bracket 93. The fourth outer tube 921 is disposed below the fourth inner tube 922. The fourth outer tube 921 includes a fourth outer tube body 921a, a third attachment plate 923 and a fourth clamping plate 924. The third clamping plate 923 and the fourth clamping plate 924 are arranged to be disposed in the extension and contraction direction of the fourth damper 92 on the side of the fourth outer tube body 921a. The third clamping plate 923 and the fourth clamping plate 924 are each provided with a mounting hole. The third clamp plate 923 is positioned above the fourth clamp plate 924. The third clamp plate 923 is positioned on the same level as the first clamp plate 913. The fourth clamp plate 924 is positioned on the same level as the second plate mounting hole 914. The mounting hole provided in the third mounting plate 923 is overlaid with the mounting hole provided in the first mounting plate 913. The mounting hole provided in the fourth mounting plate 924 is overlaid with the mounting hole provided in the second mounting plate of attachment 914.
[0299] The top of the third inner tube 912 and the top of the fourth inner tube 922 are attached to the bracket 93. The top of the third inner tube 912 and the top of the fourth inner tube 922 are connected to each other using bracket 93. The third outer tube 911 and the fourth outer tube 921 are connected to each other using a first outer connecting part 94A and a second outer connecting part 96A provided to be arranged in the direction of extension and contraction of the fourth damper 92. The third outer tube 911 and the fourth outer tube 921 are connected to each other using a first screw 94 and a second screw 96 provided to be disposed in the direction of extension and contraction of the fourth damper 92 The first outer connecting part 94A connects the top of the third outer tube 911 and the top of the fourth outer tube 921 in the direction of extension and contraction of the fourth damper 92. the outer connecting part 96A connects the lower end part of the third outer tube 911 and the lower end part of the fourth outer tube 921 in the extension and contraction direction of the fourth damper 92. The first outer connection part 94A includes the first clamping plate 913, the third clamping plate 923 and the first bolt 94. The second outer connecting portion 96A includes the second clamping plate 914, the fourth clamping plate 924 and the second bolt 96. The wheel support portion 931 is positioned below the second connecting part 96A in the extension and contraction direction of the fourth damper 92. The wheel support part 931 is arranged below the second bolt 96 in the extension and contraction direction of the fourth damper 92.
[0300] The third damper mechanism 9 includes a side support part 953A. The underside of the side support part 953A is attached to the support 93.
[0301] Figure 16(a) is a sectional view taken on line A-A of Figure 15. Figure 16(b) is a sectional view taken on line B-B of Figure 15.
[0302] As illustrated in Figure 16(a), the first external connecting part 94A connects the first clamping plate 913 and the third clamping plate 923 using the first bolt 94. A first elastic element 95 is disposed between the first bolt 94 and the mounting hole provided in the third clamping plate 923. The first elastic element 95 covers the circumference of the first screw 94 in the circumferential direction thereof.
[0303] As illustrated in Figure 16(b), the second external connecting part 96A connects the second clamping plate 914 and the second clamping plate 924 using the second bolt 96. A second elastic element 97 is disposed between the second bolt 96 and the mounting hole provided in the fourth clamping plate 924. The second elastic element 97 covers the circumference of the second bolt 96 in the circumferential direction thereof.
[0304] The configuration of the third damper mechanism 9 can be made simple as the mechanism does not require an element corresponding to the first guide 81 in the reference example mentioned above. Since the third snubber mechanism 9 includes the third snubber 91 and the fourth snubber 92, the mechanism can absorb a greater impact than the first snubber mechanism 35 and the second snubber mechanism 36. The third snubber mechanism 9 does not require high installation accuracy since the third elastic element 95 is arranged around the first screw 94 and the second elastic element 97 is disposed around the second screw 96.
[0305] (1) The suspension device (the third damper mechanism 9) according to the second mode mentioned above is equipped with the first telescopic element (the third damper 91), the second telescopic element (the fourth damper 92), the wheel support part (the wheel support part 931) and the vehicle body support part (the support 93).
[0306] The first telescopic element (the third damper 91) includes the first outer part (the third outer tube 911) and the first inner part (the third inner tube 912), an end part of which is inserted into the first part external (the third external tube 911). The first telescopic element (the third damper 91) can extend and contract by the relative movement of the first inner part (the third inner tube 912) with respect to the first outer part (the third outer tube 911).
[0307] The second telescopic element (the fourth damper 92) includes the second outer part (the fourth outer tube 921) connected to the first eternal part (the third outer tube 911) and the second inner part (the fourth inner tube 922), an end part of which is inserted into the second eternal part (the fourth outer tube 921) and which is connected to the first inner part (the third inner tube 912). The second telescopic element (the fourth damper 92) can extend and contract by the relative movement of the second inner part (the fourth inner tube 922) with respect to the second outer part (the fourth outer tube 921).
[0308] The wheel support part (the wheel support part 931) can support the wheel in the outer element including the first outer part (the third outer tube 911), the second outer part (the fourth outer tube 921) and the external connecting parts (the first external connecting part 94A, the second external connecting part 96A) which is used to connect the first external part and the second external part.
[0309] The vehicle body support part (the support 93) can support the inner element in the vehicle body of the vehicle.
[0310] The second outer part (the fourth outer tube 921) is shaped to be smaller than the first outer part (the third outer tube 911). Additionally, the second outer part (the fourth outer tube 921) is connected to the first outer part (the third outer tube 911) using the plurality of outer connection parts (the first outer connection part 94A, the second outer connection part 96A ) provided to be arranged in the direction of extension and contraction of the second telescopic element (the fourth damper 92).
[0311] The second inner part (the fourth inner tube 922) is shaped to be smaller than the first inner part (the third inner tube 912). The second inner part (the fourth inner tube 922) is connected to the first inner part (the third inner tube 912) using at least one inner connecting part (the bracket 93).
[0312] The second telescopic element (the fourth damper 92) is arranged in a position in which the direction of extension and contraction of the second telescopic element (the fourth damper 92) is parallel to the direction of extension and contraction of the first telescopic element (the third damper 91) as seen from the rotation axis direction of the wheel supported using the wheel support part (the wheel support part 931). In case the suspension device (the third damping mechanism 9) according to the second embodiment mentioned above is installed on the vehicle, the direction of the axis of rotation of the wheel is supported on the wheel support part (the wheel support part 931) is aligned with the left-right direction of the vehicle in the straight state of the vehicle. In this way, the second telescopic element (the fourth damper 92) in the state of being installed on the vehicle is arranged in a position in which the direction of extension and contraction of the second telescopic element (the fourth damper 92) is parallel to the direction of extension and contraction of the first telescopic element (the third damper 91) as observed from the left-right direction of the vehicle in the straight state of the vehicle.
[0313] In addition, the second telescopic element (the fourth damper 92) is arranged in a position in which the element is superimposed with at least part of the first telescopic element (the third damper 91) as seen from a vertical direction with respect to the geometric axis of rotation of the wheel supported on the wheel support part (the wheel support part 931). The second telescopic element (the fourth damper 92) in the state of being installed on the vehicle is arranged in a position in which the element is superimposed on at least part of the first telescopic element (the third damper 91) as seen from the front of the vehicle in the straight state of the vehicle.
[0314] With this configuration, the second outer part (the fourth outer tube 921) is smaller than the first outer part (the third outer tube 911). Additionally, the second inner part (the fourth inner tube 922) is smaller than the first inner part (the third inner tube 912). For this reason, there is a risk that the stiffness of the suspension device (the third damper mechanism 9) having this configuration may be lower than the stiffness of the suspension device (the third damper mechanism 9) equipped with two telescopic elements having the same size.
[0315] However, with this configuration, even though the second outer part (the fourth outer tube 921) is smaller than the first outer part (the third outer tube 911), the second outer part is connected to the first outer part ( the third outer tube 911) using the plurality of outer connecting parts (the first outer connecting part 94A, the second outer connecting part 96A) provided so as to be arranged in the extension and contraction direction of the second telescopic element ( the fourth damper 92).
[0316] Additionally, although the second inner part (the fourth inner tube 922) is smaller than the first inner part (the third inner tube 912), the second inner part is connected to the first inner part (the third inner tube 912 ) using at least one internal connection part (the bracket 93). In this way, the second telescopic element (the fourth damper 92) is connected to the first telescopic element (the third damper 91) at least in three positions in the direction of extension and contraction of the second telescopic element (the fourth damper 92).
[0317] Additionally, the second telescopic element (the fourth damper 92) is arranged in a position in which the direction of extension and contraction of the second telescopic element (the fourth damper 92) is parallel to the direction of extension and contraction of the first telescopic element (the third damper 91) as seen from the direction of the axis of rotation of the wheel supported using the wheel support part (the wheel support part 931).
[0318] Additionally, the second telescopic element (the fourth damper 92) is disposed in a position in which the element is superimposed with at least part of the first telescopic element (the third damper 91) as viewed from any vertical direction with respect to the geometric axis of rotation of the wheel supported on the wheel support part (the wheel support part 931). In this way, the second telescopic element (the fourth damper 92) has a function of suppressing the deformation of the first telescopic element (the third damper 91) due to the load applied from the road surface to the supported wheel, the so-called splint function. As a result, the suspension device (the third damping mechanism 9) can guarantee sufficient rigidity to support the load applied from the road surface to the supported wheel.
[0319] With this configuration, the second outer part (the fourth outer tube 921) is smaller than the first outer part (the third outer tube 911). Additionally, the second inner part (the fourth inner tube 922) is equal to or less than the first inner part (the third inner tube 912). For this reason, in case the suspension device (the third damper mechanism 9) according to the second mode mentioned above is installed in the vehicle, the interference of the two telescopic elements of the right suspension device with the left front wheel or both Telescopic elements of the left suspension device can be easily avoided. Similarly, interference between the two telescopic elements of the left suspension device with the right front wheel or the two telescopic elements of the right suspension device can be easily avoided. As a result, the vehicle equipped with the suspension device may be reduced in size.
[0320] Thus, with this configuration, the vehicle equipped with the suspension device can have its size reduced while ensuring sufficient rigidity to support the load applied from the road surface to the supported wheel.
[0321] Note that the second inner part (the fourth inner tube 922) may be the same size as the first inner part (the third inner tube 912). Also in this case, the advantage mentioned above can be obtained. Additionally, the wheel support part (the wheel support part 931) can support the wheel of the inner element including the first inner part and the second inner part (the fourth inner tube 922) connected thereto, and the second inner part (the fourth inner tube 922) connected thereto, and the vehicle body support part (the support 93) can support the eternal element in the vehicle body of the vehicle. Also in this case, the advantage mentioned above can be obtained.
[0322] (2) The suspension device (the third damping mechanism 9) according to the second mode mentioned above is additionally equipped with the following configuration.
[0323] The second outer part (the fourth outer tube 921) is made shorter than the first outer part (the third outer tube 911) in the direction of extension and contraction of the second telescopic element (the fourth damper 92). Additionally, the second outer part (the fourth outer tube 921) is connected to the first outer part (the third outer tube 911) using the plurality of outer connection parts (the first outer connection part 94A, the second outer connection part 96A ) provided to be arranged in the direction of extension and contraction of the second telescopic element (the fourth damper 92).
[0324] With this configuration (2), since the second outer part (the fourth outer tube 921), that is, the larger component in the second telescopic element (the fourth damper 92) is made shorter, the second telescopic element. co (the fourth buffer 92) can be made shorter than the first to-telescopic element (the third buffer 91). Additionally, since the second outer part (the fourth outer tube 921) is connected to the first outer part (the third outer tube 911) using the plurality of outer connection parts (the first outer connection part 94A, the second connection part external 96A) arranged in the extension and contraction direction of the second telescopic element (the fourth damper 92), the reduction in stiffness can be suppressed. For this reason, in case the suspension device (the third damper mechanism 9) according to the second mode mentioned above is installed in the vehicle, the interference of the two telescopic elements of the right suspension device with the left front wheel or both Telescopic elements of the left suspension device can be easily avoided. Similarly, interference of the two telescopic elements of the left suspension device with the right front wheel or the two telescopic elements of the right suspension device can be easily avoided. As a result, the vehicle equipped with the suspension device may be further reduced in size. Thus, with this configuration, the vehicle equipped with the suspension device can be reduced in size while ensuring sufficient rigidity to support the load applied from the road surface to the supported wheel.
[0325] (3) The suspension device (the third damping mechanism 9) according to the second mode mentioned above is additionally equipped with the following configuration.
[0326] The second telescopic element (the fourth damper 92) is shorter than the first telescopic element (the third damper 91). The first telescopic element (the third damper 91) is equipped with the component support part (the wheel support part 931) capable of supporting components in a concave part formed using the first telescopic element (the third damper 91) and the second telescopic element (the fourth damper 92) as seen from the direction of the rotation axis of the wheel supported using the wheel support part (the wheel support part 931).
[0327] Typically, the component support part (the wheel support part 931) capable of supporting the components installed in the vehicle is provided around the first telescopic element (the third damper 91) and the second telescopic element (the fourth shock absorber 92). With this configuration (3), since the second outer part (the fourth outer tube 921) is made shorter than the first outer part (the third outer tube 911) in the direction of extension and contraction of the second telescopic element (the fourth damper 92), the lower end of the second outer part (the fourth outer tube 921) is positioned above the lower end of the first outer part (the third outer tube 911) in the extension and contraction direction of the second telescopic element (the fourth damper 92) ). In this way, the concave part is formed using the first telescopic elements (the third damper 91) and the second telescopic elements (the fourth damper 92). The component support part (the wheel support part 931) capable of supporting the components installed in the vehicle (the vehicle 1001) is provided in the concave part. For this reason, the suspension device (the third damper mechanism 9) can be reduced in size. Thus, in case the suspension device (the third damper mechanism 9) according to the second mode mentioned above is installed in the vehicle, the interference of the two telescopic elements of the right suspension device with the left front wheel or the two elements telescopic of the left suspension device can be easily avoided. Similarly, interference of the two telescopic elements of the left suspension device with the right front wheel or the two telescopic elements of the right suspension device can be easily avoided. As a result, the vehicle equipped with the suspension device may be further reduced in size. Thus, with this configuration, the vehicle equipped with the suspension device can be reduced in size while ensuring sufficient rigidity to support the load applied from the road surface to the supported wheel.
[0328] Note that the component support part (the wheel support part 931) can be provided on the second telescopic element (the fourth damper 92). Also in this case, the advantage mentioned above can be obtained.
[0329] (4) The suspension device (the third damping mechanism 9) according to the second mode mentioned above is additionally equipped with the following configuration. The concave part is provided on the outer element.
[0330] With this configuration (4), the concave part is easily formed using the first telescopic element (the third damper 91) and the second telescopic element (the fourth damper 92) which is shorter than the first telescopic element (the third damper 91). Additionally, since the first outer part (the third outer tube 911) and the second outer part (the fourth outer tube 921) are connected using the plurality of outer connection parts (the first outer connection part 94A, the second external connection part 96A), the rigidity of the external element is high. Since the concave part is provided in the outer element having high rigidity, the concave part can be formed by a simple structure. For this reason, the suspension device (the third damper mechanism 9) can be reduced in size. Thus, in case the suspension device (the third damper mechanism 9) according to the present invention is installed in the vehicle, the interference of the two telescopic elements of the right suspension device with the left front wheel or the two telescopic elements of the Left hanging device can be easily avoided. Similarly, the interference of the two telescopic elements of the left suspension device with the right front wheel or the two telescopic elements of the right suspension device can be easily avoided. As a result, the vehicle equipped with the suspension device may be further reduced in size. Thus, with this configuration, the vehicle equipped with the suspension device can be reduced in size while ensuring sufficient rigidity to support the load applied from the road surface to the supported wheel.
[0331] (5) The suspension device (the third damping mechanism 9) according to the second mode mentioned above is additionally equipped with the following configuration. The inner connecting part (bracket 93) connects the other end part of the first inner part (the third inner tube 912) to the other end part of the second inner part (the fourth inner tube 922).
[0332] With this configuration (5), since the inner connecting part (the bracket 93) connects the other end part of the first inner part (the third inner tube 912) to the other end part of the second inner part (the fourth inner tube 922), the concave part is formed on an end side of the second telescopic element (the fourth damper 92) which is shorter than the first telescopic element (the third damper 91). Since the component support part can be formed using the concave part, the space can be efficiently utilized, and the suspension device (the third damper mechanism 9) can be reduced in size. Thus, in case the suspension device (the third damper mechanism 9) according to the present invention is installed in the vehicle, the interference of the two telescopic elements of the right suspension device with the left front wheel or of the two telescopic elements of the device left suspension can be easily avoided. Similarly, the interference of the two telescopic elements of the left suspension device with the right front wheel or the two telescopic elements of the right suspension device and suspension can be easily avoided. As a result, the vehicle equipped with the suspension device may be further reduced in size. Thus, with this configuration, the vehicle equipped with the device and suspension can be reduced in size while ensuring sufficient rigidity to support the load applied from the road surface to the supported wheel.
[0333] (6) The suspension device (the third damper mechanism 9) according to the second mode mentioned above is additionally equipped with the following configuration. The wheel support part (the wheel support part 931) is provided on the outer element. The vehicle body support part (the support 93) is provided on the inner element.
[0334] With this configuration (6), since the first outer part (the third outer tube 911) and the second outer part (the fourth eternal tube 921) are connected using the plurality of outer connecting parts (the first external connecting part 94A, the second external connecting part 96A), the rigidity of the external element is high. Since the wheel support part (the wheel support part 931) is provided on the external elements having high rigidity, the wheel support part (the wheel support part 931) can be formed by a simple structure. For this reason, the suspension device (the third damper mechanism 9) can be reduced in size. Thus, in case the suspension device (the third damping mechanism 9) according to the second mode mentioned above is installed in the vehicle, the interference of the two telescopic elements of the right suspension device with the left front wheel or the two elements telescopic left suspension device can be easily avoided. Similarly, interference of the two telescopic elements of the left suspension device with the right front wheel or the two telescopic elements of the right suspension device can be easily avoided. As a result, the vehicle equipped with the suspension device may be further reduced in size. Thus, with this configuration, the vehicle equipped with the suspension device can be reduced in size while ensuring sufficient rigidity to support the load applied from the road surface to the supported wheel.
[0335] This configuration (6) is preferably combined with the configuration mentioned above (3). Since the wheel support part (the wheel support part 931) is provided in the concave part formed using the first telescopic element (the third damper 91) and the second telescopic element (the fourth damper 92), the suspension (the third damper mechanism 9) can be reduced in size. Thus, in case the suspension device (the third damper mechanism 9) according to the present invention is installed in the vehicle, the interference of the two telescopic elements of the right suspension device with the left front wheel or two telescopic elements of the device of left suspension can be easily avoided. Similarly, the interference of the two telescopic elements of the left suspension device with the right front wheel or the two telescopic elements of the direct suspension device can be easily avoided. As a result, the vehicle equipped with the suspension device may be further reduced in size. Thus, with this configuration, the vehicle equipped with the suspension device can be reduced in size while ensuring sufficient rigidity to support the load applied from the road surface to the supported wheel.
[0336] (7) The suspension device (the third damping mechanism 9) according to the second mode mentioned above is additionally equipped with the following configuration. The inner connecting part (the bracket 93) connects the other end part of the first inner part (the third inner tube 912) to the other end part of the second inner part (the fourth inner tube 922). The vehicle body support part (the support 93) is provided in the internal connecting part (the support 93).
[0337] With this configuration (7), since the inner connecting part (the bracket 93) is connected to another end part of the first inner part (the third inner tube 912) to the other end part of the second inner part (the fourth inner tube 922) and the vehicle body support part (the support 93) is provided in the inner connecting part (the support 93), the distance between the first inner part (the third inner tube 912) and the second part internal (the fourth inner tube 922) can be reduced. For this reason, the suspension device (the third damper mechanism 9) can be reduced in size. Thus, in case the suspension device (the third damping mechanism 9) according to the second mode mentioned above is installed in the vehicle, the interference of the two telescopic elements of the right suspension device with the left front wheel or of the two elements telescopic left suspension device can be easily avoided. Similarly, interference of the two telescopic elements of the left suspension device with the right front wheel or the two telescopic elements of the right suspension device can be easily avoided. As a result, the vehicle equipped with the suspension device may be further reduced in size. Thus, with this configuration, the vehicle equipped with the suspension device can be reduced in size while ensuring sufficient rigidity to guarantee the load applied from the road surface to the supported wheel.
[0338] (8) The suspension device (the third damping mechanism 9) according to the second mode mentioned above can be additionally equipped with the following configuration instead of the configuration mentioned above (6). The wheel support part (the wheel support part 931) is provided on the inner element. The wheel body support part is provided on the outer element.
[0339] One end of the inner part is inserted into the outer part. In this way, the inner part is smaller than the outer part in the vertical direction with respect to the extension and contraction direction of the telescopic element. With this configuration (8), the wheel support part (the wheel support part 931) is provided on the inner element including the inner part which is smaller than the outer part. Additionally, the larger outside is arranged away from the wheel. For this reason, the suspension device (the third damper mechanism 9) can be reduced in size. Thus, in case this suspension device (the third damper mechanism 9) is installed in the vehicle, the interference of the two telescopic elements of the right suspension device with the left front wheel or of the two telescopic elements of the left suspension device may be easily avoided. Similarly, the interference of the two telescopic elements of the left suspension device with the right front wheel or the two telescopic elements of the right suspension device can be easily avoided. As a result, the vehicle equipped with the suspension device can be further reduced in size. Thus, with this configuration, the vehicle equipped with the suspension device can be reduced in size while ensuring sufficient rigidity to support the load applied from the road surface to the supported wheel.
[0340] (9) The suspension device (the third damping mechanism 9) according to the second mode mentioned above can be additionally equipped with the following configuration. The outer element includes the first everlasting part (the third outer tube 911), the second outer part (the fourth outer tube 921) and the outer connecting part. The vehicle body support part is provided in the first outer part (the third outer tube 911).
[0341] With this configuration (9), the vehicle body support part is configured using the first outer part (the third outer tube 911) which is larger than the second outer part (the fourth outer tube 921). For this reason, the suspension device (the third damper mechanism 9) can be reduced in size. Thus, in case the suspension device (the third damper mechanism 9) is installed in the vehicle, the interference of the two telescopic elements of the right suspension device with the left front wheel or the two telescopic elements of the left suspension device may be easily avoided. Similarly, the interference of the two telescopic elements of the left suspension device with the right front wheel or the two telescopic elements of the right suspension device can be easily avoided. As a result, the vehicle equipped with the suspension device may be further reduced in size. Thus, with this configuration, the vehicle equipped with the suspension device can be reduced in size while ensuring sufficient rigidity to support the load applied from the road surface to the supported wheel.
[0342] (10) The suspension device (the third damping mechanism 9) according to the second mode mentioned above is additionally equipped with the following configuration. The inner connecting part (the bracket 93) connects the other end part of the first inner part (the third inner tube 912) to the other end part of the second inner part (the fourth inner tube 922) in the same position in the extension direction and contraction of the second telescopic element (the fourth damper 92). The inner connecting part (the bracket 93) includes the upper end part of the first inner part (the third inner tube 912) and the upper end part of the second inner part (the fourth inner tube 922) in an imaginary vertical plane with relation to the direction of extension and contraction of the second telescopic element (the fourth damper 92).
[0343] With this setting (10), the inner connecting part (the bracket 93) can be made small. For this reason, the suspension device (the third damper mechanism 9) can be reduced in size. Thus, in case the suspension device (the third damper mechanism 9) according to the second mode mentioned above is installed in the vehicle, the interference of the two telescopic elements of the right suspension device with the left front wheel or of the two elements telescopic of the left suspension device can be easily avoided. Similarly, the interference of the two telescopic elements of the left suspension device with the right front wheel or the two telescopic elements of the right suspension device can be easily avoided. As a result, the vehicle equipped with the suspension device may be further reduced in size. Thus, with this configuration, the vehicle equipped with the suspension device can be reduced in size while ensuring sufficient rigidity to support the load applied from the road surface to the supported wheel
[0344] This configuration (10) is preferably combined with the configurations mentioned above from (3) to (9). With this configuration (10), the concave part formed using the first telescopic element (the third damper 91) and the second telescopic element (the fourth damper 92) can be made large. For this reason, the suspension device (the third damper mechanism 9) can be reduced in size. Thus, in case the suspension device (the third damper mechanism 9) according to the second mode mentioned above is installed in the vehicle, the interference of the two telescopic elements of the right suspension device with the left front wheel or the two elements telescopic of the left suspension device can be easily avoided. Similarly, the interference of the two telescopic elements of the left suspension device with the right front wheel or the two telescopic elements of the right suspension device can be easily avoided. As a result, the vehicle equipped with the suspension device may be further reduced in size. Thus, with this configuration, the vehicle equipped with the suspension device can be reduced in size while ensuring sufficient rigidity to support the load applied from the road surface to the supported wheel.
[0345] In case only the first damper 33 supports the first front wheel 31, the resistance in the anterior-posterior direction of the configuration supporting the first front wheel 31 is low. Thus, in the configuration in which only the first shock absorber 33 supports the first front wheel 31, the so-called judder, that is, vibration of the first front wheel 31 and second front wheel 32 in the anterior-posterior direction may occur in some cases . In the above-mentioned vehicle, the first telescopic element and the second telescopic element are arranged so as to be arranged in the anterior-posterior direction in a side view. In this way, the vehicle resistance is high in the anterior-posterior direction, and the occurrence of judder can be suppressed.
[0346] Although the inner tube is arranged above the eternal tube in the damper according to the second embodiment mentioned above, the present invention is not limited to this configuration. The three-wheeled vehicle 1 can have a configuration in which a shock absorber configured so that the inner tube is arranged below the outer tube is used.
[0347] In the second embodiment mentioned above, the first external connecting part 94A includes the first screw 94 and is connected by the first screw 94. The second external connecting part 96A includes the second screw 96 and is connected by the second screw 96.

The external connecting parts according to the present invention can merely be those used to connect the first external part to the second external part and the connecting means are not limited.
[0348] In the first embodiment mentioned above, the wheel support part can support the wheel on the outer element including the first outer part and the second outer part connected to each other. The vehicle body support part can support the inner element including the first inner part and the second inner part connected to each other in the vehicle body. However, the present invention is not limited to the first embodiment mentioned above. For example, the wheel support part can support the wheel on the inner element including the first inner part and the second inner part connected to each other, and the vehicle body support part can support the outer element including the first outer part and the second outer part connected to each other in the vehicle body of the vehicle.
[0349] In the first mode mentioned above, the second outer part is smaller than the first outer part and the second inner part is smaller than the first inner part. However, the present invention is not limited to the first embodiment mentioned above. In the present invention, the second outer part merely needs to be smaller than the first outer part. For example, the second outer part is smaller than the first outer part and the second inner part can be the same size as the first inner part.
[0350] In the first embodiment mentioned above, the first sensor support 1814 is exemplified as a component support part and the first wheel speed sensor 1081 is exemplified as a component that can be supported in the component support part. However, the component support part and the components that can be supported in the component support part according to the present invention are not limited to those according to the above mentioned embodiment. The component support part according to the present invention may be a component support part which is accommodated in the concave part formed using the first telescopic element and the second telescopic element. For example, the components that can be supported in the component support part according to the present invention can be the wheel or vehicle body structure or can be other in addition to these.

However, in the tilted state of the vehicle, the top-down direction of the vehicle body structure is tilted with respect to the top-down direction of the vehicle. Additionally, in the straight state of the vehicle, the left-right direction of the vehicle body structure coincides with the left-right direction of the vehicle. However, in the tilted state of the vehicle, the left-right direction of the vehicle body structure is tilted with respect to the left-right direction of the vehicle. In the modalities mentioned above, directions are described to indicate the top-down direction, the left-right direction, and the anterior-posterior direction. However, the top-down direction, the left-right direction and the anterior-posterior direction of the vehicle according to each of the above mentioned modalities corresponds to the top-down direction, the left-right direction and the anterior-direction. vehicle body structure as described above and can thus be replaced by top-down steering, left-right steering, and vehicle body structure anterior-posterior direction.
