The invention relates to the field of railway vehicle wheel treads, in particular to a novel wheel tread structure suitable for a linear motor subway vehicle. On the radial section of the wheel, the tread structure comprises a continuous wheel flange, a throat root circle high-taper area, a normal working area, an outer end low-taper area and a chamfering area. Wherein the normal working area comprises a normal working first section and a normal working second section which are connected in sequence; the first normally-working section is connected with the throat root circle high-taper area, the first normally-working section has the curvature radius of 300 mm, and the length of the first section is 10 mm in the axial direction of the wheel; the inclination of the second constant working section is 1: 40, and the length of the second constant working section is 21.5 mm; the outer-end low-taper area is connected with the normally-working second section, the inclination of the outer-end low-taper area is 1: 10, the length of the outer-end low-taper area is 40 mm, and the joint of the outer-end low-taper area and the normally-working second section is constructed to be of a fillet structure. According to the method, the shaking phenomenon of the train can be obviously improved, and the safety is improved.

    本申请涉及轨道车辆车轮踏面领域,具体涉及一种适用于直线电机地铁车辆的新型车轮踏面结构。在车轮的径向截面上,踏面结构包括连续的轮缘、喉根圆高锥度区域、常工作区域、外端低锥度区域和倒角区域;其中,常工作区域包括依次相接的常工作第一段和常工作第二段;常工作第一段与喉根圆高锥度区域相接,常工作第一段具有300mm的曲率半径,在车轮的轴向上,第一段长10mm;常工作第二段斜度为1:40,常工作第二段长21.5mm;外端低锥度区域与常工作第二段相接,外端低锥度区域斜度为1:10,外端低锥度区域长40mm,外端低锥度区域与常工作第二段相接处被构造为倒圆角结构。本申请能够使列车的晃动现象得到明显改善,安全性得以提高。
