The invention relates to a split type grinder, a wheel tread cleaning device for a railway vehicle, and the railway vehicle. The split type grinder comprises: a connecting piece, wherein the connecting piece is detachably mounted on a brake head of the railway vehicle; and at least two grinding sub-assemblies, wherein each grinding sub-assembly has a friction body and a support body, the friction body is arranged to provide a surface for frictional contact with a wheel tread of a rail vehicle and is connected to the connecting piece by the support body, and a gap is provided between at least two of the grinding sub-assemblies. The split type grinder is easy to manufacture, install and maintain, the temperature of the friction surface of the grinder in the using process can be effectively reduced, the probability that a wheel is scratched due to metal inlaying of the grinder is reduced, the influences of friction vibration, impact and noise are reduced, and the whole system is more stable and reliable.
本发明涉及分体式研磨子、用于轨道车辆的车轮踏面清扫装置和轨道车辆。所述分体式研磨子包括:连接件,其被可拆卸地安装到轨道车辆的闸瓦托上;至少两个研磨子组件,其中每一个研磨子组件具有摩擦体和支撑体,所述摩擦体被布置成提供用于与轨道车辆的车轮踏面摩擦接触的表面,并通过所述支撑体与所述连接件相连,并且在其中至少两个研磨子组件之间设置有间隙。本发明易于制造、安装和维护,其能够有效降低研磨子摩擦面在使用过程中的温度,减少由于发生研磨子金属镶嵌而导致划伤车轮的概率,并且减少摩擦振动、冲击和噪声的影响,使得系统整体更加稳定可靠。
