The invention discloses an elastic wheel for a rail transit vehicle. The elastic wheel comprises a wheel rim assembly, a wheel center and a damping element, wherein the wheel rim assembly is located on the periphery of the wheel center, and a gap is formed between the wheel rim assembly and the wheel center; an annular cavity with a V-shaped section is further formed in a gap between the wheel rim assembly and the wheel center, and an opening of the V-shaped section faces the wheel center; and the damping element is arranged in the annular cavity and is matched with the annular cavity in shape. The elastic wheel is advantaged in that the wheel center is an independent integral part and is connected with the wheel rim assembly through the damping element, the interference force of the damping element is relatively small in the assembling process, the wheel center cannot be deformed, the wheel center can be machined in place in one step before assembling, secondary machining after assembling is not needed, on the premise that it is guaranteed that the elastic wheel has proper rigidity performance and good vibration and noise reduction performance, the assembly process can be simpler and more convenient, machining procedures are reduced, and production cost is reduced.

    本发明公开了一种轨道交通车辆用弹性车轮,包括轮箍组件、轮心和减振元件;所述轮箍组件位于轮心的外围,并且轮箍组件与轮心之间具有间隙;所述轮箍组件与轮心之间的间隙内还形成有截面呈V形的环形腔体,并且该V形截面的开口朝向轮心;所述减振元件设于该环形腔体内,并与环形腔体的形状相匹配。本发明中的轮心是一个单独的整体部件,靠减振元件与轮箍组件连接在一起,在组装过程中减振元件的过盈力相对较小,不会使轮心产生变形,轮心可以在组装前一步加工到位,无需组装后再进行二次加工,因此,在保证弹性车轮具有合适刚度性能和良好减振降噪的前提下,能够使组装工艺更加简单方便,减少了加工工序,降低了生产成本。
