The invention relates to the technical field of railway vehicles, in particular to a shaft end grounding device, a wheel set and a railway vehicle. The shaft end grounding device is used for being installed at the shaft end of an axle. The shaft end grounding device comprises a grounding housing, a friction disc and a shaft end adapter which are connected in sequence, wherein the axle end adapteris fixedly connected with the axle end of the axle; a flaw detection channel is formed by sequentially penetrating along the axial direction of the grounding housing, the friction disc and the shaft end adapter; and the flaw detection channel is communicated with the cavity of the axle, and therefore, a through type flaw detection channel communicated with the cavity of the axle is reserved on theaxis of the axle end grounding device. Compared with the prior art, the device can realize the function of performing flaw detection operation on the hollow axle without detaching the axle end grounding device, so that the operation efficiency is effectively improved, the operation cost is reduced, and the damage risk of flaw detection operation on axle parts and the damage risk of secondary assembly of the axle end grounding device are effectively reduced, and the functionality, safety and reliability of the axle end parts and the axle end grounding device are improved.
本发明涉及轨道车辆技术领域,尤其涉及轴端接地装置、轮对及轨道车辆。该轴端接地装置用于安装在车轴的轴端,该轴端接地装置包括依次连接的接地壳体、摩擦盘和轴端适配器,轴端适配器与车轴的轴端固定连接,沿接地壳体、摩擦盘和轴端适配器的轴向依次贯通形成探伤通道,探伤通道与车轴的空腔连通,从而在该轴端接地装置的轴线上预留出与车轴的空腔连通的贯通式探伤通道,与现有技术相比,该装置实现了不拆卸轴端接地装置即可进行空心车轴探伤作业的功能,有效提高作业效率,降低作业成本,并有效降低探伤作业对车轴零部件的损伤风险、以及轴端接地装置二次组装的损伤风险,从而提高车轴端部零部件及轴端接地装置的功能性、安全性和可靠性。
