The invention relates to the technical field of railway vehicles, and provides a wheel drive system, a bogie and a railway vehicle, the wheel drive system comprises two wheel sets, each wheel set comprises a shaft sleeve and a wheel arranged at the end of the shaft sleeve, the shaft sleeve is further provided with a drive motor and a gearbox, one end of the drive motor is connected with the shaft sleeve, and the other end of the drive motor is connected with a framework; one end of the gearbox is connected with the driving motor, and the other end is connected with the shaft sleeve. By means of the mode, one end of the driving motor is connected with the framework and used for hanging the driving motor and the gearbox and bearing supporting traction and braking torque, connecting mechanisms such as hanging rods do not need to be arranged on the gearbox to be connected with the framework, and installation structures for the driving motor and the gearbox on the wheel driving system can be reduced. And the structure of the wheel drive system is lightened, and the installation space of the whole drive system is saved.

    本发明涉及轨道车辆技术领域,提供一种轮驱系统、转向架及轨道车辆,轮驱系统包括两组轮对,每一轮对包括轴套和设于轴套端部的车轮,轴套上还设有驱动电机和齿轮箱,驱动电机一端与轴套相连接,另一端与构架相连接,齿轮箱一端与驱动电机相连接,另一端与轴套相连接。通过上述方式,驱动电机一端与构架相连接,用于吊挂驱动电机和齿轮箱,承担支撑牵引和制动扭矩,齿轮箱上不用再设置吊杆等连接机构与构架相连接,有利于减少轮驱系统上对于驱动电机和齿轮箱的安装结构,而且有利于轮驱系统结构轻量化,节省整个驱动系统的安装空间。
