The invention relates to the technical field of railway vehicles, and provides a wheel set, a bogie and a railway vehicle. The wheel pair comprises a shaft sleeve structure, an axle, a pair of wheels and a connecting structure; the axle is rotationally arranged in the shaft sleeve structure; the pair of wheels is arranged at the two ends of the shaft sleeve structure respectively and rotationally connected with the shaft sleeve structure. The connecting structure is connected with the axle and the wheels and used for achieving synchronous rotation of the axle and the wheels. According to the wheel set, the bogie and the railway vehicle, the wheels are rotationally connected with the shaft sleeves, the axles are rotationally connected with the shaft sleeves, synchronous rotation between the axles and the wheels is achieved through the connecting structures, torque is transmitted between the axles and the wheels, the shaft sleeves bear bending moment, and therefore decoupling of the torque transmission function and the bearing function is achieved; the requirement on the strength of the axle is effectively reduced; in addition, the freedom degree of structural design is improved, and the overall weight is reduced.
本发明涉及轨道车辆技术领域,提供一种轮对、转向架及轨道车辆。轮对包括轴套结构、车轴、一对车轮和连接结构;车轴转动设置于所述轴套结构内;一对车轮分置于所述轴套结构的两端,且分别与所述轴套结构转动连接;连接结构分别与所述车轴和所述车轮连接,用于实现所述车轴与所述车轮的同步转动。本发明提供的轮对、转向架及轨道车辆,车轮与轴套之间以及车轴与轴套之间均采用转动连接,车轴与车轮之间通过连接结构实现同步转动,由此,车轴与车轮之间传递扭矩,轴套承受弯矩,从而实现了传递扭矩功能和承载功能的解耦,有效降低对车轴的强度要求;并且,有利于提高结构设计的自由度,减轻整体重量。
