The invention provides a novel wheel tread structure of an urban tramcar. The novel wheel tread structure of the urban tramcar comprises a rim, a throat root circle high-taper area, a normal working area, a nominal rolling circle, an outer end low-taper area and an outer end chamfering area which are sequentially and smoothly connected. According to the novel wheel tread structure of the urban tramcar in the scheme, the wheel tread curves are connected smoothly, and connecting lines among all the areas are transited smoothly and naturally; the top face of a rim in the wheel tread is of a horizontal plane structure, the extrusion strength borne by the top of the rim is reduced, the service life of the whole wheel is prolonged, curve connection of the wheel tread is smooth, transition of connecting lines between all areas is smooth and natural, the running stability, safety and comfort are improved, abrasion between wheel rails is reduced, and the performance in all aspects is good.

    本发明提供了一种城市有轨电车的新型车轮踏面结构,其包括依次平滑连接的轮缘、喉根圆高锥度区、常工作区、名义滚动圆、外端低锥度区和外端倒角区;本方案中的城市有轨电车的新型车轮踏面结构的车轮踏面曲线连接平滑,各个区之间的连接线过渡顺畅自然;其中车轮踏面中的轮缘顶面设置为水平平面结构,减少轮缘顶部受到的挤压强度,延长整个车轮的使用寿命,车轮踏面曲线连接平滑,各个区之间的连接线过渡顺畅自然,提高行驶稳定性、安全性和舒适性,降低轮轨之间的磨耗,各方面性能良好。
