Problems solved by technology

[0002] The steering performance of rail vehicles in the related art is relatively poor. In order to improve 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. The structure of rail vehicles still needs to be improved

Embodiment Construction

[0027] Embodiments of the invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary, intended to explain the present invention, but not to be construed as limitations of the present invention, those skilled in the art can change the above-mentioned embodiments within the scope of the present invention , modification, substitution and variation.

[0028] The present application is based on the inventor's discovery and recognition of the following facts and problems: in the related art, the guide wheels of the vehicle and the track are in contact with each other. There is a certain pressure in between. When the vehicle turns from a straight road to a curve, due to the extrusion of the track, the pressure between the guide wheel and the track will change. Finally, multiple guide wheels work together to provide a combined torque to realize the s...

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...
