Bogie of railway vehicle and axle box device of bogie

Abstract

The invention relates to the technical field of railway vehicles, in particular to a bogie of a railway vehicle and an axle box device.The bogie comprises a bearing beam, a front beam and a rear beam, a front axle box device is fixedly installed at the axis of the front beam, a front wheel is rotationally connected into the front axle box device, and a rear axle box device is movably installed at one end of the rear beam; the inner side of the rear axle box device is rotationally connected with a rear wheel; by arranging the bearing beam, the front beam, the rear beam, the upper spring seat, the lower spring seat, the first small spring seat, the second small spring seat, the first spring and the second spring, the front axle box device and the rear axle box device are installed on the front beam and the rear beam correspondingly, and the front beam and the rear beam are rotationally connected to the two ends of the bearing beam correspondingly; one end of the front beam and one end of the rear beam are arranged at the top and the bottom of the bearing beam through second springs, and first springs are mounted in the middles of the front beam and the rear beam through spring seats, so that stress is dispersed to the whole bearing beam, and the phenomena such as cracks caused by local stress are prevented.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a rail vehicle bogie and an axle box device thereof. Background technique [0002] Various parameters of the bogie also directly determine the stability of the vehicle and the ride comfort of the vehicle. From the early days of the founding of the People's Republic of China to the present, my country's passenger car bogies have gradually moved from backward to advanced, especially in recent years, with the loading and use of new bogies and the application of various advanced technologies, but today's bogies and their axle boxes are suspended in There are also some problems when using it. [0003] When the current bogie and its axle box device are in use, for relatively sharp curves, due to the certain distance between the front and rear wheels, the front and rear wheel edges cannot be kept parallel to the track, and the wear between the wheel and the track will be serious, ...

AI Technical Summary

Problems solved by technology

[0003]When the current bogie and its axle box device are in use, for relatively sharp curves, due to the certain distance between the front and rear wheels, the front and rear wheel edges cannot be in contact with the track. Keeping parallel will lead to severe wear and tear between the track and the friction between the wheels and the track will generate a lot of noise, and the suspension of the axle box generally acts on the two ends or the middle of the side beam, so that the side beam is partially stressed, which is easy to cause Cracks in side beams, etc., affecting driving safety
