    Tricycle
    FIELD OF THE INVENTION
    The invention relates to a tricycle comprising:
    a first part provided with two rear wheels and comprising surface parts, fixedly positioned relative to the remaining part of the first part, and arranged for placing the feet of a user thereon; and
    - a second part provided with a steerable front wheel, wherein:
    the front wheel for steering can pivot relative to the second part about a first axis; and the second part can tilt with respect to the first part about a second axis.
    BACKGROUND OF THE INVENTION
    Known are tricycles with a rigid frame. These lack a crucial feature that two-wheeled (motor) bicycles do have. This feature is that the driver, including the vehicle, can lean sideways (turning around the tangent line of the wheels with the ground plane), so that the "outward swinging effect" is absorbed in turns ("hanging in the bend"). In the same way, the cyclist is thus able to absorb irregular lateral forces that are caused by, among other things, swinging, evasive action, rough roads or gusts of wind. This feature makes driving behavior a lot safer and more comfortable and is therefore interesting to translate into tricycles. With a standard tricycle, however, it is not possible to tilt in a similar manner without a rear wheel being released from the road surface. The release of a wheel can lead to uncontrollable, unsafe situations. In order to prevent a tricycle with a rigid frame from being turned over when making a turn, the driver will often have to get out of the more safe central starting position in order to move the center of gravity with his body. Also short, irregular, (jerky) lateral forces usually have to be absorbed with the whole body, because the rigid tricycle transmits these forces. This can lead to uncomfortable and even unsafe situations. The increasing demand for higher sitting, standing function and compact, narrower designs, increases the problem of the stability, safety and comfort of such a known tricycle with a rigid frame.
    Also known are (motorized) tricycles (one wheel at the front and two wheels at the rear) with a "tilting mechanism". By turning components inwards, the center of gravity is thereby shifted in order to improve the balance, equilibrium and stability problems of these tricycles, see for example US4423795 (horizontal axis), US4064957 (horizontal axis, moving the entire seat position including footrest), US4484648 (specific spring and damping behavior), US4065144 (full body tilt, so including moving footrests, specific transmission for tilting), US4624469 (full body tilt and rear wheels), US3781031 15 (full body tilt, horizontal axis, 'tilt principle' of the whole front),
    US3601213 (whole body tilt, horizontal axis, entire front tilt, special attention to hinge), US4592441 (horizontal axis at the bottom of the frame, moving footrest, support for rotation movement), EP1070658 (system with multiple rods, driver tilt including feet) and US9487234 (complex 20 rod system, moving footrests).
    The tricycles with a "tilting mechanism" described in said patent documents, however, give the driver little or no feedback about the tilt angle with respect to the fixed world. Also, during tilting during turns, no use is made of the advantages of moving the front wheel outwards, with which the center of gravity displacement would be helped inwards. Furthermore, a "tilt mechanism" in which the tilt angle is directly linked to the headset / front fork movement will not work satisfactorily. The position of the front wheel is in fact dependent on the bend radius, while the tilt angle is related to the centrifugal force and is therefore not only dependent on the bend radius, but also on the speed and gravity, among other things. A given bend radius therefore requires different tilt angles at different speeds.
    GB2394701 describes a tricycle with a "diagonal tilting system" in which the footrests form part of a fixed, non-moving base. The tricycle is constructed in such a way that the center of gravity of the moving part (ie including the driver) moves below the pivot line of the tilting movement. The intended advantage is that during bends the center-seeking forces on the body of the driver are absorbed in a natural way by allowing the center of gravity to move freely outwards about the axle and that the vertical straight-ahead position is automatically switched on after the center-seeking forces have ended sought (similar to a hammock on which lateral forces are released). At 10 this fixed footrest has no guiding function, at most a measuring function (feedback about the angle of inclination). The major disadvantage of this system is that the stability of the entire vehicle when cornering is actually counteracted by the tilting movement within this system. The center of gravity is moved outwards, while to compensate for the center-point force, it is necessary to move the center of gravity inwards. The intersection of the hinge axis with the ground plane also coincides with the point of contact of the front wheel with the ground plane. As a result, this hinge has no run-on and in this way it also has no influence on a more stable straight-ahead drive. As a result, the shaft must be positioned relatively obliquely through the steering head in order to have sufficient trailing within the overall construction. Also, this pivotal position does not influence the left / right deflection of the front wheel when tilting, so that as such there is no advantage of the center of gravity displacement as compensation for the center-point seeking force. The use of this system for safe and comfortable standing control is impossible due to the large angle of rotation.
    GB2082987 also describes a tricycle with a "diagonal tilt system". However, there are two separate, far protruding footrests that are connected to the fixed base by means of hinges running parallel to the diagonal axis, and which move along a tilting system along with the tilting front of the vehicle. This tilting of the footrests is insurmountable within this system, because the pedals are otherwise not accessible with the feet due to a very large tilt angle. The large tilt angle is necessary to allow the vehicle to make the turns without tipping. The reason for this is the coincidence of the intersection of the diagonal axis and the ground plane with the tangent point of the front wheel with the ground plane. Just as with GB2394701, this pivot position when tilting cannot therefore positively influence the left / right deviation of the front wheel, so that also within this system there is no advantage of the center of gravity displacement as compensation for the center-seeking force. An extra large tilt angle is therefore inevitable within this system. The use of this system for safe and comfortable standing control is again difficult due to the large angle of rotation.
    Furthermore, a tricycle with a "tilting system" that is marketed 10 is known under the name "Deliver-E trike". The "tilting system" is based here on another principle whereby the axis of rotation is transverse to the longitudinal direction and is therefore provided with two independently tilting arms, so that both the wheels and the supporting surfaces for the feet tilt separately. The feet do not remain in the same plane while tilting. The result is that the feeling with the road surface is slightly increased, but because the feet move with the angle change, there is no direct feedback regarding the angle of inclination. Furthermore, the entire rear bridge is in fact a double rear bridge, which makes the number of parts unnecessarily large. Furthermore, a tricycle with a "tilting system" that is marketed under the name "De Swing Trike" is also known. This has a simple "tilt construction" in which the pivot point is arranged at the rear in the middle of the rear axle such that, with the exception of the rear axle with wheels, the entire vehicle can swing to the left and to the right along a substantially horizontal longitudinal axis. The entire body, including the feet, swings with this. So there is no question of a non-moving foot support surface, which makes a stable step difficult and a reference to the tilt angle is missing. Furthermore, it is also known to have a knee cushion in the suit of motorcyclists, with which the driver can scan the road surface when he protrudes his or her knee in curves. This gives the driver more feedback about the slope and thanks to this information more control over the permissible speed in the turn, allowing him or her to "get on the gas" faster.
    The invention now provides a tricycle that does not at least know the aforementioned disadvantages of known tricycles and also has a number of advantages of its own.
    Summary of the invention
    The invention provides a tricycle of the type mentioned in the preamble, characterized in that the second axle line has a relatively large run-on, generally between 50 and 150 cm.
    Due to the relatively large follow-up of the second axle line, the center of gravity displacement and the steering behavior in a bend are positively influenced. The first part does not tilt and thus forms a more or less stable support for the feet of a user and also a spacious and stable step surface. For example, an additional check with the fixed world has been built in, whereby useful feedback is obtained about the tilt angle, and the tilt movements can be deployed and carried out supporting, orienting and balancing. The tricycle herein preferably comprises locking means for locking the second part in a neutral position with respect to the first part, for instance when stationary or at a relatively low speed of the tricycle, which locking can again be released at a relatively high speed of the tricycle. tricycle.
    This increases the stability and improves the steering and driving behavior of the tricycle even more.

    Embodiments
    The tricycle (1) according to the invention shown in the drawings comprises a first part (3) provided with two rear wheels (14) and comprising two surface parts (19) for placing the feet of a user thereon and which act as footrests, and also a second part (4) provided with a steerable front wheel (10). Thereby, for steering, the front wheel (10) can pivot relative to the second part (4) about a first axis (24), and the second part (4) can pivot relative to the first part (3) about a second axis (23). The first axis (24) is almost vertical and has a relatively small run-on (AB), here about 5 cm. The second axis (23) runs more or less diagonally and shows a relatively large run-on (AC), here about 100 cm.
    The second part (4) also comprises a saddle (6) provided with a seat post and a seat tube (5) for receiving the seat post therein, see figure 5. Thus, the tricycle (1) can be driven while seated, see figure 1 The whole of saddle (6), seat post and a saddle tube (5) can be removed, after which the resulting opening is closed with a 'saddle stop' (7), see figure 4. Thus the tricycle (1) can be driven standing up, see figure 2. The first part (3) and the second part (4) are releasably interconnected, hinged
    The tricycle (1) also comprises checking means for checking the tilting of the second part (4) relative to the first part (3). The checking means here comprise two shock absorbers (21) whose shock-damping effect is adjustable. The shock absorbers (21) are biased here such that the second part (4) is urged to a neutral position relative to the first part (3), the "upright position", whereby the urgent action is adjustable. The checking means also comprise limiting means for limiting the tilt angle of the second part (4) relative to the first part (3). This is necessary in connection with the required stability and safety. The checking means may also comprise locking means for locking the second part in the neutral position with respect to the first part. This is advantageous or necessary if the tricycle (1) is stationary or moving slowly to prevent undesired tilting. In addition, the run-on (AC) of the second axle line (23) is then not "effective", and that is favorable because that (relatively large) run-on (AC) makes steering at relatively low speeds more difficult.
    The trailing effect from the diagonal hinge ensures that the front wheel (10) moves outwards due to tilting in bends compared to the fixed base (3), see figures 10, 5 so that the displacement of the center of gravity has a faster effect as a result to compensate for the centrifugal force. The axis (23) through the diagonal hinge makes an angle (a) with respect to the imaginary longitudinal axis, such that when the structural element (4) tilts in a certain direction, the entire tricycle (1) makes a turn in the same direction without the need for steering with the handlebar (13).
    The non-tilting part, the basic element (3), consists of a fixed bottom plate (18) which, among other things, serves as a step and is furthermore provided with fixed foot support surfaces (19). Furthermore, the basic element (3) consists of two rear wheels (14) with or without integrated wheel built-in electric motors (22), a separate space for batteries (20) and possible components such as mudguards, separate motor with differential, rear brake system and accessories such as storage basket / bin, towbar, tilt wheel and rear lighting.
    The added shock absorber structure (17) forms an adjustable or non-adjustable shock-damping connection between tilting and non-tilting parts which acts in the direction of rotation of the diagonal hinge to gradually absorb shocks. The added shock absorber construction (17) is provided with a bias in the shock absorbers (17) so that the "vertical upright position" of the mounting element (4) is guaranteed in passive condition. The fixed footrest surfaces (19) contribute to the "FM tuning" of the total shock absorber system. In addition to the shock absorbers, the legs form a "natural damping system" between the fixed and tilting parts. The shock absorber construction (17) can be detached from the mounting element (4) (unscrew or click loose), so that the mounting element (4) as a whole can tilt freely (90 ° left or right), so that a flat package remains and with it the storage space occupied is reduced, see figure 8. The shock absorber construction (17) can be unlocked from the mounting element (4), whereby the seat tube (5) and seat stop (7), whether or not fitted with a rear light unit, can serve as lock / unlock. The tricycle (1) can be divided at the location of the diagonal hinge, see figure 9, so that two parts are created and thus the total weight is distributed and lifting by a user is less stressful.
    In the tricycle (1) a renewed "tilt principle" has been applied with greatly improved properties regarding balance, balance and stability, and safety, comfort and complexity. The tricycle (1) differs from known tricycles with a "tilting system" by the special positioning of a "diagonal tilting axis" which is placed in the tricycle (1) in such a way (angle, length and position) that it has become possible to have advantages to be derived from the 'follow-up effect' steering behavior. Moreover, the first part (1) forms a fixed base that under all circumstances forms a safe and comfortable step (static) or stable orientation base (dynamic), from which the tilting movement can be controlled and very accurately deployed.
    The invention is eminently suitable for use in the rapidly growing compact electrically driven tricycles. These are tricycles with a high, vertically oriented driver's position, preferably for standing as well as seated use, for both short and longer distances and for both indoor use (such as factory halls, shops, and the like) and for outdoor use (on public roads) and in rough terrain), equipped with a large fixed base plate with space for step and foot places, with or without high seats, but in a version without 'tilt mechanism', often used for disabled use. However, the danger of tipping over is great with such a known tricycle, which can lead to dangerous situations, in particular with the target group of users. A tricycle according to the invention is provided with both a secure fixed base plate (with space for step and placement of the feet), as well as a sophisticated tilting principle, which makes the vehicle extremely suitable for people with (starting) mobility limitations.
    The present invention makes it possible that the tilting property, which is usually reserved for two-wheelers, is also applied to tricycles. The invention offers a solution for the "outward-swinging effect" of the driver and the vehicle and a solution for the lateral (whether or not shockwise) forces on the driver and vehicle. The unique application is based on tilting both vehicle parts and driver sideways, against external lateral forces. The center of gravity of gravity is thereby moved so favorably that, even with a narrow track width of the vehicle, relatively high speeds are possible in the bends, without "flying out of the bend". The basic principle here is that the driver can sit both standing and seated and that the driver places his / her feet on a non-moving solid surface (18,19). The system thus provides a stable basis from which the driver together with vehicle parts can perform all necessary lateral movements to compensate for the lateral forces. As a solution direction, the invention is based on the way in which two-wheelers such as bicycles, mopeds, scooters and motorcycles absorb lateral forces, that is to say, tilting about an axis. Different vehicles have such a "tilting principle", but with the present invention there are remarkable differences. First, the pivot axis (23) is placed at a certain angle, so that it positively influences the 'follow-up behavior', but above all a tricycle with a 'tilting system' according to the invention is based on a fixed world for the feet, from which the tilting movements are used to support, orientate and balance. A valuable advantage is that extra control with the fixed world is built in, whereby feedback is obtained about the tilt angle, so that subsequently the speed can be dosed more accurately with this information (compare the aforementioned knee cushion). The non-moving, surface orientating footrests (18, 19) are therefore a fundamental part of the invention, a highly functional support, balance and orientation basis, which as such provides more control, and therefore more safety, over the vehicle. The second important reason why the bottom plate (18) forms part of the fixed base element (3) is the step-up function. The bottom plate (18) is a component that always remains in a fixed horizontal position and therefore, regardless of the tilting inclination of the system, forms an assured stable step for the driver at all times, so that a comfortable and safe way can be taken ( standing or sitting) on the tricycle.
    In the invention, a headset hinge is used as is known from the standard bicycle. Figure 6 shows this principle. Point A is the point of contact of the front wheel with the ground plane. The steering head axis intersects the ground plane in point B. The size of the trailing edge (AB) is important for direct steering behavior (steering by steering). The greater the trajectory (AB), the better the front wheel follows the direction in which the vehicle is already moving, the better the stable vertical straight-ahead position, but also the more force it takes to change direction. If intersection (B) coincided with tangent (A), there would be no tracking and the front wheel would not follow the direction in which the vehicle is already moving. With a tricycle (1) according to the present invention, a small run-on (AB) has been chosen, whereby the tricycle (1) therefore steer relatively easily, so that it is also suitable for small spaces or spaces where a high degree of maneuverability is desired.
    Because the axis (23) of the diagonal hinge, just like the steering head hinge, also intersects the ground surface (2) and the intersection point (C) does not coincide with tangent point (A), this also influences the steering behavior of the tricycle (1) because the diagonal hinge has a run-on (AC), see figure 7. However, with the steering head hinge, the run-on (AB) is only determined relative to the moving parts around the front fork, while with the diagonal hinge the run-on (AC) relative to of the entire building element (4) is determined. To create a good, stable "straight-through position" of the whole, it is beneficial to choose a relatively large after-run (AC). The size of this after-run (AC) therefore largely determines the sense of stability of the whole and in particular the steerability at higher speeds and weaker curves. The associated optimum angle α can therefore be estimated, but is also determined by, among other things, the position of the diagonal hinge. This in turn depends on the desired wheelbase of the vehicle. Furthermore, the optimum angle is dependent on the damping and springing force of the shock absorber construction (17). With (electrically driven) "Trikes" with sit and stand function 25, a short wheelbase is highly desirable. For example, with a wheel base of 85 cm, the optimum diagonal hinge angle (α) is ~ 15 ° for comfortable steering.
    Furthermore, the size of the run-on during turns also has a major influence on the position of the front wheel relative to the starting position, see figure 10. The run-on (AB) is relatively small, so this run-on will, in turns, affect the position of the front wheel. have little influence over the initial position. With the diagonal hinge, however, a large run-on has been chosen, so that with this larger run-on (AC) the front wheel is forced more outwards with respect to the fixed base element (3) during turns. As a result of this effect, less tilt angle is required to move the center of gravity favorably towards the inner bend. In short, in curves, relatively speaking, only a small tilt angle is required to absorb the centrifugal forces with great effect, thanks to the displacement of the front wheel towards the outer bend, which is mainly caused by trailing (AC). Here somewhere there is an optimum that is determined by a compromise between on the one hand the advantage of making a small tilt angle (little physical movement required) and on the other hand the 'sensibility' of the tilting movement (fine-tuning of the movement, the approaching) of fine motor skills). The optimum angle α is between 12 and 10 17 °. This also depends on the damping and springing force of the shock absorber construction (17).
