The embodiment of the invention provides a wheel, a bogie and a railway vehicle. The wheel comprises a hub, a spoke and a wheel rim which are sequentially arranged from inside to outside. The hub and the wheel rim are made of a second type of metal; the spoke is made of a first type of metal alloy; an annular mounting groove or an annular convex part is arranged on the peripheral surface of the spoke; the density of the first metal alloy is smaller than that of the second metal; an annular mounting groove or an annular convex part is arranged on the inner circumferential surface of the wheel rim, the annular mounting groove and the annular convex part on the outer circumferential surface of the spoke correspond to the annular mounting groove and the annular convex part on the inner circumferential surface of the wheel rim, and the annular convex part is embedded into the annular mounting groove and used for axially limiting the spoke and the wheel rim. According to the wheel, the bogie and the railway vehicle provided by the embodiment of the invention, the problem of high difficulty in hot charging or press mounting of a traditional split type wheel can be solved, the weight of the wheel is relatively light, the lightweight design of the bogie is favorably realized, and the wheel rail noise is reduced.
本申请实施例提供一种车轮、转向架及轨道车辆,车轮包括:从内向外依次设置的轮毂、轮辐和轮箍;轮毂和轮箍采用第二类金属制成;轮辐采用第一类金属合金制成;轮辐的外周面设有环形安装槽或环形凸部;第一类金属合金的密度小于第二类金属的密度;轮箍的内周面设有环形安装槽或环形凸部,轮辐外周面和轮箍内周面的环形安装槽、环形凸部对应设置,环形凸部嵌入环形安装槽内用于对轮辐与轮箍进行轴向限位。本申请实施例提供的车轮、转向架及轨道车辆能解决传统分体式车轮热装或压装所存在的难度大的问题,且车轮的重量较小,有利于实现转向架的轻量化设计,并降低轮轨噪音。
