The invention discloses a subway bogie wheel driving system and a bogie with the same, and belongs to the technical field of rail transit vehicle bogies, the driving system is externally arranged on the outer side of a bogie frame, and the driving system comprises a traction motor and a rotating arm installed at the end of an axle; an end cavity is formed in the position, located above the rotating arm, of the end of the framework side beam and used for installing a traction motor, and the traction motor drives the axle to drive the wheels to rotate through a transmission mechanism; the transmission mechanism is provided with a power input end A and a power transmission end B, and the power input end A and the power transmission end B are distributed on the two sides of the axle; wherein one end of the rotating arm is rotationally connected with the framework side beam, the other end of the rotating arm is connected with the framework side beam through the primary suspension, the driving system achieves light weight, meanwhile, the usable design space of the bogie is increased, the maintainability of the bogie is improved, and on the basis that the weight and load distribution of the bogie are optimized, the service life of the bogie is prolonged. Vibration and impact between wheel rails are effectively reduced, and the bearing structure of the bogie is optimized.

    本发明公开了一种地铁转向架车轮驱动系统及具有该驱动系统的转向架,属于轨道交通车辆转向架技术领域,驱动系统外置于转向架构架外侧,其包括:牵引电机、安装于车轴端部的转臂;以及构架侧梁,构架侧梁端部位于转臂上方形成有端腔,用于安装牵引电机,牵引电机通过传动机构驱动车轴带动车轮旋转;传动机构具有动力输入端A和动力传递端B,且动力输入端A和动力传递端B分布于车轴两侧;其中,转臂一端与构架侧梁旋转连接,另一端通过一系悬挂与构架侧梁连接,该驱动系统实现了在轻量化的同时,增加转向架可使用的设计空间,提升了转向架的可维护性,并且在优化转向架重量及载荷分布基础上,有效减小轮轨间的振动和冲击,优化转向架承载结构。
