Definitions

  • the present invention relates to a bogie for a railway vehicle, connected to the vehicle body by a load cross member, and to one or two axles and corresponding motors, with transmission between a motor and the wheels which it drives comprising a mechanical differential.
  • differential reduction bridge In known bogies with mechanical differential, all of the organs which ensure the transmission of movement between a motor and the corresponding wheels are gathered in a carrying beam, generally called “differential reduction bridge", which simultaneously performs the support functions of load, driving the bogie and transmitting the engine torque.
  • the use of such a differential reduction bridge leads to a structure in which the frame and the bogie suspensions are arranged between the running wheels and the longitudinal axis of the bogie. It causes the presence of unsprung masses vis-à-vis the important track (reduction bridge, transmissions, braking devices, engine).
  • differential reduction axles have only been used on bogies intended for rolling on tires (subway bogies), for which the presence of large unsprung masses was not a major drawback, taking into account the additional suspension provided by the tires themselves.
  • the present invention aims to provide a bogie for a rail vehicle between an engine and the wheels which it drives comprising a mechanical differential, with a reduction to a very large extent of the unsprung masses, both vertically and transversely, and an arrangement suspension members further from the longitudinal axis than the wheels.
  • the bogie according to the invention is characterized in that the motor and its differential are suspended from the load cross member.
  • Figure 1 shows schematically a known bogie.
  • FIG. 2 schematically represents a bogie according to the invention with a single axle.
  • Figure 3 shows in perspective a bogie according to the invention.
  • the body C rests by means of a ball ring C r on the load cross member T.
  • the latter carries via suspensions S1 and S2 on the differential bridge P , forming a supporting beam.
  • the motor M is fixed to the differential bridge P. Its shaft is connected by a coupling to the mechanical differential D, which drives the lateral reducers Rd1, Rd2 by lateral shafts.
  • the wheels R1, R2 are integral with the ends of the differential bridge, and driven by the output shafts of the reducers Rd1, Rd2.
  • the mechanical differential transmits the movement on both sides to the reducers lateral Rd1, Rd2, which are semi-suspended from the load cross member T, by lateral couplings with large clearance AC1, AC2 able to take up the transverse deflections between the axle E and the cross member T.
  • the bogie suspensions are arranged outside the wheels with respect to a longitudinal axis, which improves their accessibility.
  • FIG 3 shows in perspective with partial cutaway a bogie meeting the basic structure of Figure 2.
  • the motor M is connected by a coupling AC3 to the mechanical differential D. Both are suspended under the cross member T.
  • the output shafts of the differential are connected by couplings AC1, AC2 to the reducers Rd1, Rd2, which transmit the movement to the wheels R1 , R2.
  • the axle is bent. It has a lower central part E0 and raised ends E1, E2 opposite the false axle boxes FB1, FB2, arranged outside the wheels. These false axle boxes support the coil suspension springs S1, S2 on one side, S3, S4 on the other.
