  • This transmission shaft includes a ball-and-finger connection known as a Cardan joint, in order to accommodate variations in orientation and lateral movements between the body and the bogie, and therefore the significant movements between the engine and the axle.
  • a Cardan joint a ball-and-finger connection known as a Cardan joint
  • transmission via a universal joint is non-linear and causes energy losses in the transmission from the engine to the axle.
  • An aim of the invention is thus to provide a high-speed rail vehicle bogie comprising a transmission system making it possible to dispense with the “tripod” type shaft.
  • the subject of the invention is a railway vehicle bogie according to claim 1.
  • Such a bogie makes it possible to dispense with the tripod by eliminating the need to accommodate significant lateral clearances between the engine and the axle.
  • the invention also relates to a high-speed rail vehicle comprising at least one bogie as described above, the rail vehicle being intended to move at speeds greater than or equal to 300 km/h during high-speed travel phases. speed.
  • the bogie 10 equips a high-speed rail vehicle, that is to say a rail vehicle capable of moving at speeds greater than or equal to 300 km/h during high-speed travel phases.
  • the bogie 10 is described below with reference to a longitudinal direction elevation direction Z-Z', substantially orthogonal to the longitudinal direction X-X' and the transverse direction Y-Y'.
  • the longitudinal direction X-X' and the transverse direction Y-Y' are substantially horizontal and the elevation direction Z-Z' is substantially vertical, when the bogie 10 runs normally on substantially horizontal rails.
  • the bogie 10 comprises a chassis 12, comprising longitudinal members 14 and at least one crosspiece 16 forming a frame.
  • the bogie 10 also includes axles 18 and wheels 20 supporting the chassis 12 through primary suspension systems 22.
  • the wheels 20 and the axles 18 are mounted on the chassis 12 in a rotary manner in order to allow the bogie 10 to circulate on a railway track.
  • the bogie 10 further comprises at least one motor 24 and at least one reduction gear 26 intended to drive the axles 18 and the wheels 20 in rotation.
  • the chassis 12 comprises in particular two longitudinal members 14 and a crosspiece 16, assembled so as to form a frame having a substantially H shape, by sets of fixings (not shown) arranged at the ends of the crosspiece 16.
  • the longitudinal members 14 extend substantially parallel to each other, in the longitudinal direction X-X', and the or each crosspiece 16 extends substantially in the transverse direction Y-Y'.
  • the bogie 10 comprises two motors 24 and two reduction gears 26 arranged on either side of the crosspiece 16, each motor 24 driving one of the axles 18 via one of the corresponding reduction gears 26.
  • a single motor 24, a single reduction gear 26 and a single axle 18 have been shown, the others being arranged substantially symmetrically with respect to the center of gravity of the chassis 12.
  • the axles 18 extend substantially parallel to each other, in the transverse direction Y-Y'.
  • the longitudinal members 14 of the chassis 12 extend above the axles in the direction of elevation Z-Z', and are carried by the suspension systems primary 22 (not visible on the figure 1 ) which rest on the ends of each axle 18.
  • the wheels 20 are for example arranged internally with respect to the longitudinal members 14 and the primary suspension systems 22, in the transverse direction Y-Y'.
  • Each primary suspension system 22 comprises, in known manner, at least one shock absorber and at least one elastic return element, such as a spring.
  • the shock absorber and the elastic return element are both arranged between the spar 14 and the axle 18, and are arranged to absorb the shocks and vibrations transmitted from the wheel 20 to the chassis 12.
  • Each motor 24 comprises a protective casing 28, as well as, in known manner, a stator contained in the casing for its protection and a rotor rotatably mounted in the stator (not shown in the figures).
  • Each engine 24 is a high-speed railway vehicle engine, that is to say capable of making the railway vehicle reach a speed greater than or equal to 300 km/h.
  • Each motor 24 has a mass greater than or equal to 900 kg, preferably 1100 kg.
  • the rotor rotates a rotor shaft 29 linked to a coupling device 30 which mechanically connects the motor 24 to the reduction gear 26.
  • the coupling device 30 is positioned between the rotor shaft 29 and the reduction gear and in particular between the rotor shaft 29 and an input pinion 48 of the reducer 26.
  • the coupling device 30 advantageously comprises a coupling with convex teeth comprising an input adapted to cooperate with the rotor shaft 29 and an output adapted to cooperate with an input pinion 48 of the reduction gear 26.
  • the cambered tooth coupling makes it possible to compensate for axial, radial and angular misalignments between the rotor and the gearbox 26, in particular between the rotor shaft 29 and the input pinion 48 of the gearbox 26.
  • the coupling is said to have convex teeth because it includes on its periphery at its entry and exit teeth having convex and not straight edges.
  • the teeth are particularly suitable for cooperating with complementary housings formed on the periphery of a sleeve of the coupling extending between the inlet and the outlet.
  • cambered tooth coupling is for example as described in WO 97/47894 A1 to figures 1 and 5.
  • the carcass 28 comprises side walls 32, for example substantially cylindrical, two end flanges 34 closing the side walls 32, and superstructures 36 (not shown on the figures 2 And 3 ), playing a heat dissipation role in particular.
  • the carcass 28 defines a plurality of fixing points 40, arranged opposite a support 42 carried by the crosspiece 16 when the engine is mounted on the chassis.
  • the carcass 28 defines four fixing points 40, arranged at the four corners of a rectangle, with two of the fixing points 40 located above a median plane of the chassis 12 substantially perpendicular to the direction of elevation Z- Z', and the two other fixing points 40 located below said median plane of the chassis 12.
  • the median plane of the chassis 12 is in particular a substantially horizontal plane, extending halfway up the crosspiece 16 and the longitudinal members 14, in the direction of elevation Z-Z', when the railway vehicle travels on horizontal rails.
  • Each fixing point 40 comprises for example a through conduit having substantially smooth internal walls, suitable for receiving a bolt.
  • each fixing point 40 comprises a threaded orifice, opening at one or both ends, suitable for receiving a screw.
  • the support 42 is for example a plate substantially perpendicular to the longitudinal direction
  • Rigid fixing members 46 are engaged in a locking manner both in the orifices 44 of the support 42 and in the conduits of the fixing points 40 of the carcass 28.
  • the fixing members 46 are for example bolts.
  • the fixing members 46 are screws or rivets.
  • each fixing point 40 comprises two substantially parallel conduits passing through, and the support 42 defines two orifices 44 facing each fixing point 40, each orifice 44 opening into one of the conduits.
  • Each fixing member 46 comprises two bolts substantially parallel to each other, each engaged in one of the orifices 44 and in one of the conduits. This embodiment makes it possible to increase the stiffness of the mounting of the motor 24 and to improve its safety.
  • Each reducer 26 comprises the input pinion 48, cooperating with the output of the coupling device 30, and an output pinion 50 secured to the axle 18.
  • the reducer 26 transmits the mechanical drive of the coupling device 30 to the axle 18, which allows the motor 24 to drive the wheels 20 in rotation.
  • Each reducer 26 is fixed to the chassis 12 by a respective suspension system, presenting a single vertical degree of freedom, that is to say allowing advantageously travels of the reduction gear essentially in the direction of elevation Z-Z'.
  • the suspension system of the reduction gear 26 comprises for example a pivot connection allowing articulation of the reduction gear 26 in rotation relative to the chassis 12, around an axis substantially collinear with a central axis of the coupling device 30, such as a link 54 elastic return.
  • the articulation of the reducer 26 around the central axis of the coupling device 30 makes it possible to minimize the relative movements of the motor 24 and the reducer 26 at the level of its input pinion 48, which makes it possible to use the device coupling 30 instead of a “tripod” type shaft.
  • the reduction gear 26 ensures a substantially linear transmission of the drive of the motor 24 to the wheels 20, that is to say that the torque transmitted to the wheels 20 depends substantially linearly on the torque generated by the motor 24, without non-linearities during rotation as is the case with a Cardan joint.
  • the reducer 26 does not include an element having a chrome surface, because no element requires significant hardness.
