The invention relates to the technical field of railway vehicles, and provides a shaft sleeve structure, a wheel set, a bogie and a railway vehicle. The shaft sleeve structure comprises a first shaft sleeve and a second shaft sleeve; the first shaft sleeve and the second shaft sleeve are coaxial, are arranged on the two sides of the gearbox respectively and are suitable for being fixedly connected with the gearbox respectively. The first shaft sleeve and the second shaft sleeve are respectively provided with an axial shaft penetrating hole, and the shaft penetrating holes are suitable for penetrating an axle coaxially fixed with a wheel; the first shaft sleeve comprises a first pipe body close to the gear box and a second pipe body far away from the gear box, the second shaft sleeve comprises a second pipe body, the first pipe body is of a sleeve structure with a round inner side and a square outer side, and the second pipe body is of a round sleeve structure and is suitable for being rotationally connected to the inner side of a wheel. The axle can only transmit torque, the first shaft sleeve and the second shaft sleeve play a bearing role, the torque transmission function and the bearing function are decoupled, good bending resistance is achieved, and the safety coefficient is effectively improved.
本发明涉及轨道车辆技术领域,提供一种轴套结构、轮对、转向架及轨道车辆。轴套结构包括第一轴套和第二轴套;第一轴套和第二轴套共轴线,第一轴套和第二轴套分置于齿轮箱的两侧,且分别适于与齿轮箱固定连接;第一轴套和第二轴套分别设置有轴向的穿轴孔,穿轴孔适于穿设与车轮同轴固定的车轴;第一轴套分别包括靠近齿轮箱的第一管体和远离齿轮箱的第二管体,第二轴套包括第二管体,第一管体为内侧呈圆形且外侧呈方形的套管结构,第二管体为圆形套管结构,第二管体适于转动连接于车轮的内侧。本发明可以使车轴仅传递扭矩,第一轴套和第二轴套起承载作用,实现传递扭矩功能和承载功能解耦,具有良好的抗弯能力,有效提高安全系数。
