  • the current rapid passenger electric locomotive uses a traction motor elastic frame suspension structure, as shown in Fig. 2 .
  • a hollow shaft of a six-link hollow shaft is sleeved on the axle 5, the six-link of the six-link hollow shaft is fixedly connected with the wheel pair, and a suspension cross beam is sleeved on an outer surface of the hollow shaft.
  • one end of the suspension cross beam 8 is connected with the traction motor 3, and the traction motor 3 is suspended on a middle cross beam 11 of the framework 1 through a suspension rod 9.
  • a gear box 2 is arranged on the same side of the suspension cross beam and the traction motor, an output shaft of the traction motor 3 is connected with a driving gear in the gear box 2, and one side of the gear box body is fixedly connected with a side face of the suspension cross beam 8 by bolts.
  • a suspension point is arranged at the other end of the suspension cross beam 8, another suspension point is arranged at one end of the gear box body away from the traction motor 3, and the two suspension points are elastically suspended on a framework end beam 12 through the suspension rod.
  • the gear box 2 is installed on the gear hub 400 through a bearing and forms an integral unit with the traction motor 3.
  • the gear box bears a part of force.
  • the gear box adopts the above load bearing structure, the heavy load will increase the complexity of the structural stress of the gear box, resulting in easier damage to the gear box.
  • Longitudinal direction a direction along a rail.
  • Transverse direction a direction vertical to the rail in the horizontal plane.
  • CN 104608787 A discloses a broad gauge three axle combustion engine steering frame.
  • the present invention aims at providing a bogie that can ensure the transverse stability, avoid stress on a gear box, prevent the damage to the gear box, is reasonable in structural stress and is suitable for fast heavy-duty freight electric locomotives with running speeds higher than 120km/h.

  • the traditional transmission mode is shown in Fig. 2 , one end of the six-link is connected with the gear hub of the driven gear via bolts, and the other end of the six-link is connected with the wheel pair to transmit force through the gear hub. While in the present solution, the driven gear is directly connected with the six-link through the transmission pin, so that the transmission of force is more direct, the middle part is reduced, the stress is better, and the failure rate is lower.
  • one end, without the through groove, of the beam body is provided with a symmetrical pair of transverse backstop mounting seats, a transverse backstop is installed on each transverse backstop mounting seat, and the top of the transverse backstop is fixedly connected with the frame end beam.
  • the gear box is lubricated with grease to avoid the problem of oil leakage of the driving device, and the sealing structure of the gear box can also be simplified.
