Abstract

The invention discloses a railway vehicle driving system and a bogie. The device comprises a traction motor, a gear transmission device, an axle, a coupling sleeved on the axle, and a suspension cross beam; the gear transmission device comprises a small gear box body, a large gear box body, a small gear, an idle gear, an idle gear shaft, a large gear and a gear hub; the idle gear shaft is supported in the small gear box body, and the idle gear is supported on the idle gear shaft; the idle gear shaft is of a hollow structure, the large end of the idle gear shaft is fixedly connected with one side end of the small gear box body, and the small end of the idle gear shaft is inserted into the blind hole structure on the other side of the small gear box body; the bull gear is fixedly connected with the gear hub, and the bull gear and the gear hub are supported on the bull gear box body; and the small gear is in meshing transmission with the idle gear, and the idle gear is in meshing transmission with the large gear. The problems of fast steel rail abrasion, line deformation, sleeper breakage, abnormal wheel abrasion and the like caused by the conditions of the prior art can be solved.

Description

technical field [0001] The invention relates to a rail vehicle drive system and a bogie, belonging to the technical field of rail vehicles. Background technique [0002] Large axle load and long marshalling is the development trend of bulk cargo railway transportation, but the increase of axle load and traction weight requires the increase of single axle traction force and traction power, which inevitably leads to the increase of traction motor weight and volume, the existing heavy load Freight locomotives usually use traction motors and gear transmissions to hold shafts for suspension. The unsprung weight is large, and the wheel-rail action force is large. The wheel-rail action force is caused by a series of problems such as rapid wear of the rail, deformation of the line, breakage of the sleeper, and abnormal wear of the wheel. The main reason is, therefore, for heavy-duty freight locomotives, it is a technical problem to be solved urgently to adopt the suspension structur...
