Self-deflecting embedded bogie and track car

Abstract

The invention discloses a self-deflecting embedded bogie and a track car. The self-deflecting embedded bogie comprises two walking mechanisms arranged symmetrically; each walking mechanism comprises astructural support, a walking wheel and two steering wheels, wherein the walking wheel is suitable for walking along the top surface of a track beam, and the two steering wheels are arranged in the front-back direction and are suitable for walking close to the inner side of the track beam; in the two symmetric walking mechanisms, an elastic part is arranged between axles of at least the two steering wheels on the front side, and the elastic part is used for driving the two corresponding steering wheels to move away from each other. According to the self-deflecting embedded bogie of the embodiment, as the elastic part is arranged between the axles of at least the two steering wheels on the front side in the two symmetric walking mechanisms, the requirement for strength of the bogie and thesteering wheels is lowered, the risk of tire burst of the steering wheels is lowered, and the vehicle driving safety is improved.

Description

technical field [0001] The invention relates to the field of rail transportation equipment, in particular to a self-deflecting built-in bogie and a rail car. Background technique [0002] In the rail transportation industry, the traveling wheels and steering wheels are generally fixed on the bogie. When this type of bogie turns, the whole bogie deflects slightly through the rebound force of the track beam on the steering wheel. This type of bogie is steered by the huge interaction force between the steering wheel and the track beam, and it is difficult to deflect greatly, which limits the turning radius. Moreover, the huge force of the steering wheel and the track beam has higher requirements on the bearing capacity of the track beam, bogie, and steering wheel, and the huge pressure also makes the steering wheel have the risk of blowing out. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior ...

AI Technical Summary

Problems solved by technology

This form of bogie is steered by the huge interaction force between the steering wheel and the track beam, and it is difficult to deflect in a large extent, which limits the turning radius

Moreover, the huge force between the steering wheel and the track beam has higher requirements on the bearing capacity of the track beam, bogie, and steering wheel, and the huge pressure also makes the steering wheel have the risk of blowing out.
