Backbone type double-axle power bogie for straddle type monorail vehicle

Abstract

The invention relates to a bogie for a straddle type monorail transport vehicle, in particular to a backbone type double-axle power bogie for a straddle type monorail vehicle. The backbone type double-axle power bogie comprises a central traction device mounting beam, wherein a backbone integrated with the central traction device mounting beam is arranged at the middle part of the central traction device mounting beam; two guide wheel mounting beams integrated with the backbone are respectively arranged at the two ends of the backbone; two steady wheel support arms integrated with the central traction device mounting beam are respectively arranged at the two ends of the central traction device mounting beam; guide wheel support arms integrated with the guide wheel mounting beams are respectively arranged at the two ends of the guide wheel mounting beams; the central traction device mounting beam is integrated with the backbone and the two guide wheel mounting beams, so that a backbone type bogie body is formed. The backbone type double-axle power bogie for the straddle type monorail vehicle is compact in structure, reduces the overall volume, reduces the vertical vehicle through cross section, lightens the overall weight, is uniform in load during operation, reduces the wear probability of travelling wheels during operation, prolongs the service lives of the travelling wheels, improves the safety in operation, and lowers the later maintenance cost and operating cost.

Description

technical field [0001] The invention relates to a bogie for a straddle-type monorail traffic vehicle, in particular to a bogie with compact structure, reduced volume, reduced vertical passing section of the vehicle, reduced overall weight, reduced wear probability of running wheels during operation, extended service life of running wheels, improved A spine-type dual-axle power bogie for straddle-type monorail vehicles that improves operational safety and reduces operating costs. Background technique [0002] The straddle-type monorail vehicle is supported by the bogie, see attached figure 1 with 2 , the technical solution shown in the figure is the "mesh" type bogie commonly used at home and abroad. The "mesh"-shaped bogie generally includes a mesh-shaped frame body (1) enclosed by a frame, a central traction device installation beam (2) located in the middle of the mesh-shaped frame body (1), and a mesh-shaped frame body ( 1) There are two driving wheel axles (3) fixed o...

AI Technical Summary

Problems solved by technology

The running wheels (4) are located in the middle of the mesh-shaped frame (1). The two rubber tires in each running wheel (4) are supported by a cantilever beam, driven by a drive shaft, and supported by a cantilever beam. Although the wheel (4) facilitates the replacement of rubber tires, the single cantilever beam structure leads to uneven force on the mesh-shaped frame (1), complex structure, and large mass, uneven load on the running wheel (4), and eccentric wear of the tires ; The rubber running tires used have a high flatness rate, which makes the hub structure complex and heavy, and the operation of replacing tires is cumbersome, time-consuming, and low in efficiency, that is, high maintenance costs; two motors are installed diagonally on the frame (1). side, which also causes uneven stress on the mesh-shaped frame (1)

[0004] To sum up: the existing technology has complex structure, large mass, large volume, uneven load during operation, short service life of tires, cumbersome operation of replacing tires, long time consumption, low efficiency and high operating costs
