Abstract

The invention discloses a wheel for a railway vehicle. The wheel for the railway vehicle comprises a rim, a rim root, a tread and a tread outer side which are connected in sequence. The tread comprises a first tread arc section, a tread straight line section and a second tread arc section which are sequentially connected head to tail. One end of the first tread arc section is connected with the rim root, one end of the second tread arc section is connected with the tread outer side, and the first tread arc section, the tread straight line section and the second tread arc section are matched with a track in appearance. A rim outer side and the tread of the wheel for the railway vehicle can be accurately matched with the track in appearance, and thus the wheel has good dynamics performance and contact fatigue performance.

Description

technical field [0001] The present invention relates to a wheel, in particular to a wheel for a railway vehicle. Background technique [0002] The wheel of a railway vehicle is a key component of a railway vehicle. Its shape is closely related to the dynamic performance of the vehicle, which affects the safety of the train and the wear of the wheel-rail system. For a long time, the shape of the wheel obtained by using the traditional empirical design method, especially the outer side of the rim and the shape of the tread, cannot be accurately matched with the track, and the dynamic performance and contact fatigue performance of the wheel are poor. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the traditional wheels used for railway vehicles in the prior art, whose shape cannot be accurately matched with the track, and the dynamic performance and contact fatigue performance of the wheels are relatively poor, an...
