The bogie 2 of FIG. 1 is a railway vehicle engine bogie intended to move along a railroad track comprising two parallel rails R paralleled by a dashed line in FIG. 1. In the rest of the description, FIG. The terms "longitudinal", "transverse", "horizontal" and "vertical" refer to the bogie 2 placed on the railway and moving longitudinally along the railway. The bogie 2 comprises two axles 4, a chassis 6 bearing on the axles 4 via primary suspensions 8, and two motor / gearbox assemblies 10. The bogie 2 comprises a secondary suspension 12 for the support of a body of a railway vehicle on the chassis 6. Each axle 4 comprises two coaxial wheels 14 centered on an axle axis E. The axle axis E is transverse. The two wheels 14 of each axle 4 are spaced transversely so that each wheel 14 can roll on a respective rail R. Both axles 4 are spaced longitudinally. The axles E axles of the two axles 4 are parallel to each other and spaced longitudinally. The two wheels 14 of each axle 4 are integral in rotation around the axle axis E of this axle 4. Each axle 4 comprises an axle shaft 16 linking the two wheels 14 of the axle 4 in rotation around the axle 4. Axle axle E. The axle shaft 16 of each axle 4 extends transversely along the axle axis E, between the wheels 14 of this axle 4.
    [0003] The axle shaft 16 is coaxial with the wheels 14. Each axial end of the axle shaft 16 is integral in rotation with a respective wheel 14 of the axle 4. Each axle 4 comprises two axle boxes 18 each axle box 18 receiving a respective axial end of the axle shaft 16 rotatable about the axle axis E. The chassis 6 comprises two longitudinally extending rails 20 and two cross members 22 extending transversely between the longitudinal members 20. The two side members 20 are spaced transversely and the two cross members 22 are spaced longitudinally. The two longitudinal members 20 and the two crosspieces 22 together form a frame 24.
    [0004] The chassis 6 bears on the axles 4 via the primary suspension 8. The primary suspension 8 here comprises two leaf springs 26. Each leaf spring 26 is formed of a stack of resiliently flexible blades, or a single blade. In the first case, the blades of each leaf spring 26 are preferably of decreasing length in the stack, the blades being stacked from the longest blade to the shortest blade. The blades are preferably metal blades. Each leaf spring 26 extends longitudinally between the two axles 4 while bearing at its ends on the axles 4. Each end of the leaf spring 26 bears on a respective axle 4, more specifically on an axle box 18 of a respective axle 4. Each spar 20 bears on a respective leaf spring 26. Each spar 20 bears substantially in the middle of the leaf spring 26. Each spar 20 has a length less than the distance between the two axes of axles E.
    [0005] Both axles 4 are engines. Each motor / gearbox assembly 10 is configured to rotate the two wheels 14 of a respective axle 4. Each motor / gearbox assembly 10 comprises a motor 30 and a gearbox 32. The motor 30 of each motor / gearbox assembly 10 is coupled to the wheels 14 of the corresponding axle 4 via the gearbox 32 of this motor / gearbox assembly 10. Each motor / gearbox assembly 10 is preferably electromechanical, the motor 30 being an electric motor. The motor 30 and the gearbox 32 of each motor / gearbox assembly 10 are integral with each other and fixed to the two side members 20 in such a way that the motor / gearbox assembly 10 forms a crossmember 22 solidarizing the two side members 20.
    [0006] The motor 30 and the gearbox 32 of each motor / gearbox assembly 10 are each attached to a respective spar 20. The motor 30 and the gearbox 32 of each motor / gearbox assembly 10 are here fixed integrally to each other, each being fixed integrally to a respective spar 20. The motor 30 and the gearbox 32 of each motor / gearbox assembly 10 each form a respective section of the crossmember 22 formed by this motor / gearbox assembly 10. The motor 30 extends between a beam 20 and the gearbox 32, and the gearbox 32 extends between the motor 30 and the other spar 20.
    [0007] The motor 30 and the gearbox 32 each have a respective housing, namely a crankcase 34 and a gearbox 36. The motor 30 and the gearbox 32 are fixed integrally to one another by their housings and each fixed to a respective spar 20 by its housing. The crankcase 34 and the gearbox 36 of each motor / gearbox assembly 10 together form a structural crossmember 22 of the frame 6. Each crossmember 22 thus integrates the motor housing 34 and the gearbox 36 of a motor / gearbox assembly 10. motor housing 34 and the gear housing 36 each form a respective section of the cross member 22 formed by the motor / gearbox assembly 10. The motor housing 34 extending transversely between a beam 20 and the gearbox 34, and the gearbox 36 extends transversely between the crankcase 32 and the other spar 20. Alternatively, a motor / gear unit 10 has a common housing for the motor 30 and the gearbox 32. In another variant, the motor 30 is devoid of crankcase. In particular, a motor is for example fixed by its stator to the spar 20 and the gearbox 32. The two motor / gearbox assemblies 10 are arranged head to tail. The motor 30 and the gearbox 32 of a motor / gearbox assembly 10 are arranged head to tail relative to those of the other motor / gearbox assembly 10. A motor / gearbox assembly 10 has its motor 30 adjacent to a spar 20 and its gearbox 32 adjacent to the other spar 20, while the other motor / gearbox assembly 10 has its motor 30 adjacent said other spar 20 and its gear 32 adjacent said spar 20. Each spar 20 connects a respective motor 30 of a set motor / gearbox 10 to the gearbox 32 of the other motor / gearbox assembly 10.
    [0008] The motor 30 of each motor / gear unit 10 is in transverse position. The motor 30 has a transverse motor axis M. The motor axis M is the axis of the output shaft 38 of the motor 30. The gear 32 has an input axis coaxial with the motor axis M and an output axis substantially coaxial with the axle axis E of the corresponding axle 4. The output shaft 38 of the motor 30 of each motor / gearbox assembly 10 is coupled to the wheels 14 of the corresponding axle 4 via the gearbox 32. The gearbox 32 comprises an input 32A coupled to the motor 30 and an output 32B coupled to the wheels 14 of an axle 4. The gear reducer 32 comprises, at its input 32A, a rotatable input member 40 rotatably coupled to the motor shaft 38 of the motor 30 and at its output 32B a rotary output 42 rotatably secured to the axle shaft 16. The input member 40 and the output member 42 are rotatably connected with a reduction ratio. The input member 40 and the output member 42 are connected in rotation for example by a gear transmission (s), a belt transmission, a chain transmission. As illustrated in Figure 1, the input member 40 and the output member 42 are two mutually meshing gears. The bogie 2 comprises elastic couplings 44 arranged between the output 32B of the gearbox 32 of each motor / gearbox assembly 10 and the wheels 14 of the corresponding axle 4. The coupling 44 is configured to allow axial movement, radial clearance and / or angular misalignment between the output 32B of the gearbox 32 and the wheels 14 of the axle. More specifically, the coupling 44 is arranged between the output 32B of the gearbox 32 and the axle shaft 16 and allows axial misalignment, radial misalignment and / or angular misalignment between the output 32B of the gearbox 32 and the shaft 16. The coupling 44 here comprises a hollow tubular shaft 46 threaded onto the axle shaft 16 received inside the hollow shaft 46, and elastic elements 48 interposed on the one hand between the hollow shaft 46 and the axle shaft 16 to join in rotation about the axle axis E, and secondly between the hollow shaft 46 and the output 32B, while allowing relative movement. The elastic elements 48 are for example rings of elastomeric material. The hollow shaft 46 is substantially coaxial with the output member 42 and integral in rotation with the output member 42. The frame 6 has no additional crossbar in addition to the crosspieces 22 each formed by a motor / gear unit 10. Thus, each crossmember 22 of the chassis 6 is formed by a motor / gearbox assembly 10. The side members 20 are integrally connected exclusively by the or each motor / gearbox assembly 10 forming a crossmember 22. The bogie 2 is provided to receive the vehicle body rail support vertically on the frame 6 through the secondary suspension 12. The secondary suspension 12 comprises for example pneumatic diaphragm springs 50. The pneumatic diaphragm springs 50 are arranged on the longitudinal members 20. A pneumatic diaphragm spring 50 is disposed on each spar 20. The bogie 6 comprises a horizontal connection device 52 for linking the rail vehicle body to the frame 6 in a horizontal plane. The horizontal connecting device 52 is arranged in the space defined between the two crosspieces 22. The horizontal connecting device 52 comprises a rocker 54 adapted to receive a pivot of the rail vehicle body, the rocker 54 being connected to each of its ends 58 to a respective cross member 22 by a connecting rod 60. Each connecting rod 60 is here connected to the motor housing 34 integrated in the cross member 22 correspondingly.
    [0009] The bogie 2 comprises a respective braking device 62 associated with each wheel 14. Each braking device 62 comprises pistons 64 integral with the longitudinal members 20 and making it possible to move the friction pads 66 in contact with the treads of the corresponding wheels 14. Other types of braking systems are possible. For example, the pistons may be replaced or supplemented by disc and caliper assemblies placed outside the wheels 14. Other types of primary suspension 8 and secondary suspension 10 are possible. Thus, the bogie 2 of Figure 2 differs from that of Figure 1 in that the primary suspension 8 comprises primary suspension springs 68 disposed between the ends of the longitudinal members 20 and the axle boxes 18. Each primary suspension spring 68 is disposed between a respective spar end 20 and the associated axle box 18. The longerons 20 are longer than those of the bogie of Figure 1, so that their ends pass over the axle boxes 18 and are supported on these axle boxes through the primary suspension springs 68 The primary suspension springs 68 are, for example, helical springs. Thanks to the invention, the or each motor / gear unit forms a cross member of the bogie frame connecting the longitudinal members of the bogie. The motor and the gearbox are therefore integrated into the chassis. This avoids additional sleepers. As a result, the truck is solid, yet compact and lightweight.
    [0010] In addition, each motor / gearbox assembly is suspended relative to the axles via the primary suspension. Each motor / gearbox assembly 10 is therefore part of the suspended masses of the bogie. The elastic coupling between the gearbox and the associated axle shaft ensures that the gearbox is fully suspended.
    [0011] The unsprung masses of the bogie are therefore limited, which is favorable to the dynamic behavior of the bogie and the protection of the railway infrastructure. The chassis of the bogies of Figures 1 and 2 has two cross members, each formed by a motor housing and a reducing housing of a drive assembly. Alternatively, a frame comprises a single cross member having at least a length portion formed by a motor housing and a reducing housing of a drive assembly. In Figures 1 and 2, the axle boxes 18 of each axle 4 are disposed inside the wheels 14. The side members 20 are arranged transversely between the two wheels 14 of each axle 4.
    [0012] In a variant, the axle boxes 18 of each axle 4 are arranged outside the wheels 4. The two wheels 14 of each axle are arranged transversely between the two longitudinal members 20. The invention is not limited to a bogie railway vehicle. In general, it applies to a guided land vehicle bogie, that is to say configured to circulate along at least one rail being guided by this rail.
