Railway vehicle and guiding wheel device used for railway vehicle

Abstract

The invention discloses a railway vehicle and a guiding wheel device used for the railway vehicle. The guiding wheel device comprises a bracket, travelling wheels and at least one guiding wheel pair; the travelling wheels are arranged on the bracket in a pivot mode and supported on railways to move; two guiding wheels of each guiding wheel pair abut against two opposite outer side walls of the railways to move; and each guiding wheel is connected with the bracket in a pivot mode through a corresponding hydraulic cylinder assembly and driven by the hydraulic cylinder assembly to move to adjust the distances between the guiding wheels and the outer side walls of the railways. According to the guiding wheel device used for the railway vehicle of the embodiment of the invention, pressure adjusting between the guiding wheels and the railways can be achieved, and steering performance of the vehicle is improved.

Description

technical field

[0001] The invention relates to the technical field of rail transit vehicle bogies, and more particularly, to a guide wheel device for a rail vehicle and a rail vehicle with the guide wheel device. Background technique

[0002] The steering performance of rail vehicles in the related art is relatively poor. In order to improve the steering performance, structures such as spring assemblies or cam mechanisms are used to assist steering. These structures are relatively complicated, inconvenient to install, and have low operational reliability. There is still room for improvement. Contents of the invention

[0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. To this end, the present invention proposes a guide wheel device for rail vehicles, which can improve the steering performance of the vehicle.

[0004] The invention also proposes a rail vehicle having the above-mentioned guide wheel a...
