The invention relates to the technical field of railway vehicles, and provides a shaft end transmission device, a wheel set and a bogie, the shaft end transmission device comprises a shaft end spline, a flexible plate and a connecting plate, the shaft end spline is provided with a connecting hole, and a mandrel is inserted into the connecting hole. The flexible plate shaft end spline is connected with the flexible plate through a first connecting piece. One end of the connecting plate is connected with the flexible plate through a second connecting piece, and the other end is connected with the wheel through a third connecting piece. By means of the mode, the end of the mandrel is connected with the shaft end spline and used for transmitting power to wheels, the mandrel is not directly connected with the bogie, force of the bogie and a vehicle body is not directly applied to the mandrel, axial force and pressure borne by the mandrel are greatly reduced, the diameter of the mandrel can be smaller under the condition that the service life of the mandrel is not affected, and the service life of the mandrel is prolonged. And the requirement of light weight is met.

    本发明涉及轨道车辆技术领域,提供一种轴端传动装置、轮对及转向架,轴端传动装置包括轴端花键、挠性板以及连接板,轴端花键具有连接孔,连接孔用于插接芯轴。挠性板轴端花键通过第一连接件与挠性板相连接。连接板一端通过第二连接件与挠性板相连接,另一端通过第三连接件与车轮相连接。通过上述方式,芯轴端部与轴端花键相连接,用于对车轮传递动力,芯轴不与转向架直接连接,进而转向架以与车体的力不直接施加于芯轴,由此芯轴受到的轴向力和压力大大减小,芯轴在不影响使用寿命的情况下可以直径更小,满足轻量化的要求。
