    专利说明:

    [0001] The present invention relates to a motorized bogie for a low-floor railway vehicle.
    [0002] A motorized bogie is intended in particular to equip a railway vehicle whose body is arranged in two stages of passenger transport. Usually, both stages extend along a central portion A of the body which is located between two bogies (as shown in Figure 6). Access doors to the vehicle, allowing passengers easy access to the vehicle from the dock or dock from the vehicle, are also located between the two bogies. Indeed, because of the height of a conventional bogie, it is not possible to arrange an access door to the right of such a bogie, because the height of this door would then be incompatible with the height of the dock . Conventionally, the doors are arranged next to the bogies of the railway vehicle.
    [0003] Such an arrangement of the doors is not entirely satisfactory. Indeed, the central part of the body, in which are arranged the two floors, is thus limited by bogies and doors. Usually, a single-storey compartment is fitted to the bogies, but such a compartment can only accommodate a small number of passengers.
    [0004] The invention is intended to overcome this disadvantage, by proposing a motorized bogie to increase the number of passengers that can be transported in a rail vehicle. For this purpose, the subject of the invention is a motorized bogie for a railway vehicle, comprising: a chassis, comprising: two longitudinal members extending parallel to one another and parallel to a longitudinal direction; two sleepers, carried by the longitudinal members, extending parallel to one another, and parallel to a transverse direction perpendicular to the longitudinal direction, - two supports, each support being carried by the two sleepers, - two structures of axles, each comprising two axle boxes each connected to a respective one of the longitudinal members, and a transverse axle shaft, extending in the transverse direction between two ends each carrying a respective wheel, the wheels defining each other an interior space, delimited in the transverse direction 3029879 2 between the wheels of the same axle shaft, and delimited in the longitudinal direction between the two shafts of essie ux, - at least one motor carried by one of the crossmembers of the chassis, arranged in the interior space delimited by the wheels, and comprising a coupling shaft, 5 - at least one gearbox providing the mechanical connection between the shaft coupling of the engine and one of the transverse axle shafts, characterized in that: - the bogie comprises primary suspension means, comprising first suspension elements arranged between the cross members and the chassis side members, - the The reducer is arranged outside said interior space, the engine coupling shaft extending from the engine beyond one of the corresponding longitudinal members to the gearbox. In a bogie of the state of the art, the primary suspension means are arranged outside the interior space, and the gearbox is arranged in this interior space. Such a gearbox is particularly bulky, especially in height, so that it is the height of the gear that imposes the low limit of the distance between a wheel support plane and a rail vehicle body carried by the bogie. According to the invention, the structure of the primary suspension means, the first suspension elements of which are arranged in the interior space, makes it possible to release space outside this interior space. It is then possible to arrange the gearbox outside the interior space, so that this reducer is no longer arranged to the right of the rail vehicle body. Thus, in the invention, the gearbox does not affect the minimum distance between the support plane 25 of the wheels and the railway vehicle body. In a bogie according to the invention, this minimum distance is imposed by the top of the axle boxes, which have a height less than that of the gearbox. Thus, in the invention, the minimum distance between the wheel support plane and the railway vehicle body is less than that imposed by the structure of a bogie state of the art. The box being lowered, it is possible to arrange a door of this box to the right of the bogie, this door can be arranged at dock level. This makes it possible to increase the length of the central part of the box where the two floors are arranged. As the length of the two floors is increased, the passenger capacity in the box is thus increased.
    [0005] The motorized bogie according to the invention may comprise one or more of the following characteristics, taken individually or in any technically possible combination: each axle structure is connected to a respective one of the longitudinal members by a parallel axis articulation in the transverse direction, and - the primary suspension means comprise, for each axle structure, at least a second suspension element arranged between the axle structure and the spar; - Secondary suspension means, carried by each frame support, 10 and having support means to a rail vehicle body, the secondary suspension means being arranged transversely at least partially outside the interior space; each first suspension element has a ring shape and is made of an elastic material, this first suspension element being interposed radially between one of the cross-members of the chassis and the edges of an orifice formed in one spars; each first suspension element is made of rubber; each first suspension element has an annular shape defined between an inside diameter and an outside diameter, the difference between this inside diameter and this outside diameter being substantially equal to 100 mm; each second suspension element is formed by a connecting rod. The invention also relates to a rail vehicle comprising a body, characterized in that it comprises a bogie as defined above. Advantageously, the railway vehicle comprises one or more of the following characteristics, taken separately or in any technically possible combination: the body comprises at least one access door arranged at the bogie's right; the distance, in a vertical direction perpendicular to the longitudinal and transverse directions, between the access door and a support plane of the wheels is less than or equal to 850 mm. The invention will be better understood on reading the description which will follow, given solely by way of example, and with reference to the appended drawings, in which: FIG. 1 is a perspective view of a bending frame; a railway vehicle bogie according to an exemplary embodiment of the invention; and FIG. 2 is a perspective view of a railway vehicle bogie including the frame of FIG. 1; and Figure 3 is a top view of the bogie of Figure 2; and Figure 4 is a side view of a bogie of the state of the art; and Figure 5 is a side view of the bogie of Figure 2; and FIG. 6 is a schematic side view of a state-of-the-art railway vehicle; and Figure 7 is a schematic side view of a railway vehicle whose body is equipped with bogies similar to that of Figure 2.
    [0006] In the present description, the terms "vertical" and "horizontal" are defined according to their usual meanings, with respect to a bogie mounted in a railway vehicle. Thus, a horizontal plane is substantially parallel to a plane in which bogie axles extend and a vertical plane is substantially parallel to a plane in which bogie wheels extend.
    [0007] The term "longitudinal" is defined in its usual sense as applying to the direction in which a rail vehicle extends in a horizontal plane, and the term "transverse" is defined according to its usual meaning as applying at a direction substantially perpendicular to the longitudinal direction in a horizontal plane. A reference numeral is shown in the figures, in which a longitudinal direction 20 is designated by the reference X, a transverse direction is designated by the reference Y, and a vertical direction, perpendicular to the longitudinal X and transverse Y directions, is designated by the reference Z. Furthermore, the terms "front" and "rear" are defined according to their usual meanings relative to the direction of movement of the railway vehicle in the longitudinal direction X. By convention, in the figures, the term "before" corresponds to to the left and the word "back" to the right. It should be noted that a rail vehicle can usually travel in two opposite directions, the terms "front" and "rear" being then inversely reversed when the direction of travel is reversed. FIG. 2 shows a railway vehicle bogie 10, for example for a low-floor regional express transport train (TER). FIG. 1 also shows a frame of this bogie 10. The bogie 10 comprises two pairs 12 of wheels 14, arranged respectively at the front and at the rear of the bogie 10. The wheels 14 of each pair 12 are carried and connected to each other by an axle structure 30 respectively to this pair 12.
    [0008] Each axle structure 30 comprises two axle boxes 32, namely one for each wheel 14, as well as an axle shaft 34 extending in the transverse direction Y between two ends, each of which carries a wheel. 14 respective. In the present description, an inner space I, delimited in the transverse direction between the wheels 14, and in the longitudinal direction, is defined between the axle shafts 34. The axle structures 30 carry a frame 15 through the axle. intermediate joints 36 and primary suspension means 40, which will be described later. The frame 15 comprises two lateral side members 16, of the rocker type, each extending parallel to the longitudinal direction X, two crosspieces 17, each extending parallel to the transverse direction Y, thus transversely to the side rails 16, and two supports 18, of the console type, intended to receive the body 60 of the railway vehicle. Each spar 16 is connected at one of its ends to a respective axle box 32 by means of a respective hinge 36. Each articulation 36 comprises, for example, a rod with an axis parallel to the transverse direction Y, carried at the end of the corresponding spar 16, cooperating with a complementary pivot element carried by the axle box 32. This pivot element is worn. below a top of the axle box 32, in the vertical direction Z, so that the spar 16 extends below this apex of the axle box 32. More particularly, this vertex 32 the axle box 32 imposes a minimum limit on a height at which can be arranged a box 60 of the railway vehicle, carried by the bogie 10. In other words, the minimum value of a distance D, shown in FIG. 5, between a support plane of the wheels 14 and support means 25 52 to the rail vehicle body 60 is imposed by the height of this axle box top 32. It will be noted that, in the state of the technique, as shown in FIG. 4, the minimum value A distance D between a support plane of the wheels 14 'and support means 52' to a rail vehicle body 60 'is imposed by the height of a top of a gearbox. Thus, this distance D 'in a bogie 10' of the state of the art is greater than the distance D of the bogie of the invention. The primary suspension means 40 comprise first suspension elements 42, arranged between the crosspieces 17 and the longitudinal members 16, providing the connection between these crosspieces 17 and these longitudinal members 16.
    [0009] More particularly, first transverse openings 19 are formed in the longitudinal members 16 to receive the crosspieces 17. Advantageously, the first transverse openings 19 have a cross section of generally identical shape to that of the cross section of the cross members 17, for example a circular section. Each crossmember 17 passes through a respective one of the first transverse openings 19 of each spar so that each crossmember 17 extends laterally beyond the spars 16. The two crosspieces 17 carry together, at each of their ends, respective one of the supports 18 for receiving the body 60 of the railway vehicle. In the example described, each crosspiece 17 has a diameter less than a diameter of the openings 19, so that a free annular space is defined between the crosspieces 17 and the longitudinal members 16. As indicated above, the first suspension elements 42 are advantageously arranged in the free annular spaces between the longitudinal members 16 and the cross members 17. As can be seen in FIG. 1, representing a preferred embodiment, the first suspension elements 42 each have a generally annular shape, and each form a resilient connection between one of the longitudinal members 16 and a respective one of the crosspieces 17. The annular suspension member 42 has an outer diameter defined in a plane XZ having the longitudinal X and vertical directions Z and an inside diameter defined in FIG. XZ plane. A difference between this outer diameter and this inner diameter is preferably 100 mm, which corresponds substantially to the difference between the diameter of the cross member 17 and the diameter of the corresponding opening 19. On the other hand, the suspension element 42 has a dimension in the transverse direction Y of between 100 and 150 mm. These first suspension elements 42 are made of an elastic material, for example rubber. Note that the first suspension elements 42 are less eccentric than conventional primary suspension means. More particularly, considering a center of the bogie C, shown in FIG. 3, defined as a point longitudinally at mid-distance between the axles 30, and transversely at mid-distance between the planes of the wheels 14, the distance between the first and second axles. suspension elements 42 and the center C is smaller than the distance between conventional primary suspension means and a center C of the state of the art. Thus, when the truck passes over track defects (also called "left"), the vertical movement of the first suspension members 42 is less than the vertical displacement of conventional primary suspension means. Since the vertical displacement experienced by the first suspension members 42 is reduced, the dimensions of these first suspension members 42 in the vertical direction Z are reduced relative to those of conventional primary suspension means. The primary suspension means 40 further comprise second suspension elements 44, arranged between the longitudinal members 16 and the axle boxes 32. More particularly, as can be seen in particular in FIG. 1, each second suspension element 44 is arranged between one end of a respective one of the longitudinal members 16 and one of the axle boxes 32, this second suspension element 44 being intended to damp a relative rotational movement of the spar 16 and the corresponding axle box 32 around the joint 36. Each second suspension element 44 comprises for example an arm extending substantially in the longitudinal direction X from the end of the corresponding spar 16, to the corresponding axle box 32, to which it is connected by a pivot connection. Each second suspension element 44 is for example arranged, relative to the vertical direction Z, below the hinge 36 carried by the same end of the spar 16. Each second suspension element 44 is for example formed by a connecting rod. FIG. 3 shows two motors 20 which are each carried respectively by one of the crosspieces 17. These motors are arranged in the interior space I delimited by the wheels 14. Each motor is of the "fast" type, that is, that is to say that it operates at a high rotation speed (number of revolutions per minute), and consequently has a reduced bulk. Conventionally, each motor 20 is connected to at least one of the pairs 12 of wheels 14 by means of a coupling shaft 22 and a gearbox 24. The coupling shaft 22 of the motor 20 passes through a spar 16 through an opening 21. Thus, the coupling shaft 22 extends from the interior of the interior space I towards the outside of this interior space I. For example, the shaft of coupling 22 comprises gear coupling means.
    [0010] Advantageously, the gearbox 24 is connected to the support 18 of the frame 15 by means of a reaction rod 25, stabilizing the gearbox 24 vertically at the coupling shaft of the engine 22. The bogie 10 also comprises means secondary suspension means 50, carried by the support 18 of the frame 15, at least partially outside the interior space I. More particularly, the secondary suspension means 50 are arranged 3029879 8 outside a zone Inside the transverse direction Y between the longitudinal members 16. Advantageously, the highest point of the secondary suspension means 50 is located below the top of the wheels 14 in the vertical direction Z, as shown in FIG. The height of this highest point of the secondary suspension means 50, taken from a support plane of the wheels 14 is for example substantially equal to 700 mm. The secondary suspension means 50 are equipped with support means 52 to the body 60 of the railway vehicle, making it possible to receive all the vertical forces exerted by the body 60 on the bogie 10. As can be seen by comparing FIG. 4 , which represents a conventional bogie 10 'of the state of the art, with FIG. 5, which represents a bogie 10 according to the invention, the structure of the bogie 10 according to the invention allows the arrangement of the secondary suspension means 50 at a height lower than that of the state of the art.
    [0011] Due to this reduced height, it is possible to arrange an access door 62 of the box to the right of the truck 10. The box 60 of the railway vehicle thus comprises at least one access door 62 arranged at the bogie right 10 (as shown in Figure 7). The maximum height of a floor at the foot of the door is 850 mm, measured from the support plane 20 of the wheels 14 (thus from the rails). Thus, the height of the door 62 is compatible with the height of a conventional platform, which ensures passengers to easily get on and off the rail vehicle. As can be seen by comparing FIG. 6, representing a railway vehicle of the state of the art, and FIG. 7, representing a railway vehicle 25 according to the invention, the longitudinal displacement of the doors 62 to the right of the bogies 10 (FIG. FIG. 7) makes it possible to arrange a two-stage central portion B over a greater length than the central portion A of the conventional vehicle (FIG. 6). The railway vehicle of the invention therefore has two levels longer, and therefore has a greater capacity for passenger transport.
    [0012] Note that the invention is not limited to the embodiment described above, but could have various variants without departing from the scope of the claims. In particular, the invention could be applied to a bogie carrier, not including a motor. Furthermore, the joints 36 between the longitudinal members 16 and the axle boxes 32 could have a different structure than that previously described.
    [0013] Lastly, the bogie 10 according to the invention could equip any other rail vehicle than a regional express transport train, for example a tramway, metro or a mainline train. 5
