Definitions

  • the present invention relates to a railway vehicle engine bogie, of the type comprising at least one pair of wheels, the wheels of the or each pair being connected to each other by a shaft to form an axle, the bogie further comprising a motor for driving the axle in rotation about its axis.
  • the invention also relates to a railway vehicle comprising such a bogie.
  • each motorized bogie In a railway vehicle, each motorized bogie, or motor bogie, generally comprises two pairs of wheels, the wheels of a pair being connected to each other by a shaft to form an axle, a chassis connecting said axles one to the other, suspensions interposed each between a half-frame and an axle, said suspension allowing a relative vertical displacement of the axle relative to the corresponding half-frame, and means for driving in rotation of the one axles or each axle.
  • These drive means comprise at least one motor and a kinematic chain ensuring the transmission of engine torque from the engine to the axle, as well as the transmission of the braking torque from the axle to the engine.
  • the drive means are differentiated by the distribution of their masses which are either “not suspended”, that is to say related to the axle, or “suspended”, that is to say related to the chassis of bogie above the suspensions.
  • These drive means differ in their ease of integration into the bogie in terms of size, whether in width (that is to say parallel to the axis of the axle) or in length (parallel in the direction of travel of the vehicle). They differ in complexity by the number of pieces they understand.
  • An object of the invention is to provide a rail vehicle engine bogie for arranging in the frame of the body a wide bottom aisle, without requiring the realization of important steps in the floor of the railway vehicle to pass over the bogie .
  • the motor bogie incorporates axle drive means which are both compact and powerful, that said drive means are simple to implement, and that the unsprung masses are reduced.
  • the invention also relates to a railway vehicle, in particular a tram, comprising a motor bogie as defined above.
  • a horizontal plane is substantially parallel to the plane in which the axles extend and the vertical plane is substantially parallel to the plane in which the wheels extend.
  • the term “longitudinal” is defined with respect to the direction in which a railway vehicle extends in a horizontal plane and the term “transverse” is defined in a direction substantially perpendicular to the longitudinal direction in a horizontal plane.
  • Each of the motor bogies 10 represented on the Figure 1 and 3 , comprises two pairs of wheels 20, the wheels 20 of each pair being connected to each other by a shaft to form an axle 22.
  • the axles 22 are connected to one another by a frame 24, said interior, comprising two half-frames each secured to a respective axle 22.
  • inner frame it is meant that longitudinal members 26 of each half-frame extend inside the jig formed by the wheels 20, that is to say that they are arranged between the wheels 20.
  • a primary suspension 30 is interposed between each spar 26 and the axle box 28 on which said spar 26 rests.
  • This primary suspension 30 allows inter alia relative vertical displacement of the axle 22 relative to the half-frame, that is to say that the half-frame is movable and suspended relative to the axle 22 in a direction substantially vertical.
  • At least one of the axles 22, or both axles 22, are rotated by drive means comprising a motor 34 and a kinematic chain ensuring the transmission of the engine torque from the motor 34 to the axle. 22, as well as the transmission of the braking torque from the axle 22 to the motor 34.
  • This drive train comprises a gearbox 36 and a transmission shaft 38, for the transmission of the drive from the motor 34 to the gearbox 38.
  • the motor 34 is disposed outside the template formed by the wheels 20. In other words, it is arranged transversely outside the bogie 10 relative to the wheels 20.
  • the motor 34 is also substantially coaxial with the axle 22, at the clearances allowed by the suspension 30 near.
  • the motor 34 comprises a rotor 42 and a stator 44.
  • the stator 44 is connected to the frame 24 by a first connecting member 46.
  • This connecting member 46 is adapted to take up the torques between the stator 44 and the frame 24.
  • the rotor 42 is coaxial with the stator 44.
  • Bearings 48 connect the rotor 42 to the stator 44, while allowing the rotor 42 to rotate about its axis relative to the stator 44.
  • the stator 44 is mounted around the rotor 42, so that the motor 34 forms an internal rotor motor.
  • the gearbox 36 is also disposed outside the jig formed by the wheels 20. It is in particular arranged at an opposite axial end of the axle 22 relative to the motor 34, so that the motor 34 and the gearbox 36, together transversely frame the axle 22.
  • the gearbox 36 is an epicyclic gearbox. It comprises in known manner a plurality of meshing elements 50, 52, 54, 56, including an inner sun gear 50 forming an input gear of the gearbox 36, substantially coaxial with the axle 22, a ring 52 coaxial to the sun gear. inside 50, a plurality of satellites 54 interposed between the inner sun gear 50 and the ring gear 52, each geared to the inner sun gear 50 and the ring gear 52, and a planet carrier 56, coaxial with the inner sun gear 50 and the ring gear 52, on which each satellite 54 is rotatably mounted about its axis.
  • the inner sun gear 50 is integral in rotation with the shaft 38.
  • the ring gear 52 is connected to the frame 24 by a second connecting member 58 adapted to take up the torques between the ring gear 52 and the frame 24.
  • the planet carrier 56 is secured to of the axle 22, in particular of one of the wheels 20 of the axle 22.
  • the axle 22 is hollow and defines an internal axial tubular cavity 60 opening at two axial ends 62, 64 of the axle 22.
  • the shaft 38 extends into said cavity 60, from one to the other of the axial ends 62, 64.
  • the shaft 38 has two opposite coupling portions 66, 68 each protruding outside the cavity 60 at each of the axial ends 62, 64.
  • each of the coupling sections 66, 68 has ribs 74 each projecting radially from a peripheral face of the section 66, 68 and being oriented axially, said ribs 74 being distributed over the periphery of the section 66, 68 and cooperating with grooves complementary (not shown) formed in the walls in the cavity 70, 72 in which it is received.
  • the shaft 38 is substantially coaxial with the axle 22, that is to say that the axis of the shaft 38 intersects the axis of the axle 22, the angle between the two axes being always, in absolute value, less than 1 °.
  • the bogie 10 also comprises a braking device of the axle 22, adapted to exert a resistant torque on the axle 22 so as to immobilize it in rotation relative to the frame 24.
  • this braking device comprises a disk brake 76 and a caliper (not shown), the yoke being integral in translation in the longitudinal direction of the frame 24 or the gearbox 36, and being adapted to clamp the brake disc 76 so as to prevent any displacement of the brake disc 76 relative to the stirrup.
  • the gearbox 36 is interposed between the brake disc 76 and a wheel 20 of the axle 22.
  • the brake disc 76 is in particular integral with the inner sun gear 50.
  • transmission joint includes a mechanical system for the mutual drive of two rotating parts whose axes of rotation occupy variable relative positions during operation.
  • the rotor 42 drives the transmission shaft 38 in rotation about its axis. This rotation is transmitted, through the second coupling section 68, to the inner sun gear 50 of the gearbox 36.
  • the inner sun gear 50 in turn drives the satellites 54 which roll on the ring 52. In doing so, the satellites 54 drive the rotation of the planet carrier 56 about its axis and, as a result, the rotation of the axle 22.
  • This embodiment makes it possible to limit the unsprung masses.
  • the motor 34 is semi-suspended.
  • the first connecting member 46 is a connecting rod allowing movements due to movements between the frame 24 and the axle 22.
  • the axle 22 comprises an outer portion 80 projecting outside the template formed by the wheels 20, the rotor 42 defining a cylindrical cavity 82 for receiving said outer portion 80 and being mounted on said section 80 via bearings 84.
  • the rotor 42 drives the transmission shaft 38 in rotation about its axis. This rotation is transmitted, via the second coupling section 68, to the inner sun gear 50 of the gearbox 36.
  • the inner sun gear 50 in turn causes the satellites 54 which roll on the ring 52. In doing so, the satellites 54 cause the planet carrier 56 to rotate about its axis and, as a result, the rotation of the axle 22.
  • the axes of the motor 34 and the gearbox 36 together follow the displacement of the axle 22. Said axes thus remain aligned.
  • the shaft 38 does not incline with respect to the axle 22, so that it is possible to reduce the diameter of the tubular cavity 60.
