The invention discloses a rear driving wheelof an electrically driven electric automobile. The rear driving wheel structurally comprises a rear arch frame, a movable bent rod, a movable transverse frame, a cable, a rear driving wheel, a rear axle transverse frame and a center spring. The rear driving wheel has the advantages that the rear driving wheels are installed at the two sides of the rear axle transverse frame, the rear axle cross frame, the rear arch frame, the movable bent rod, the movable cross frame and the center spring are connected to form a vibration reduction rear suspension, and the rear arch frame is fixedly installed on the automobile chassis; the rear driving wheels are independently driven by the driving motor, and an independent vibration reduction structure and an independent heat dissipation structure are formed on the rear driving wheels, the stability and the heat dissipation effect of the driving motor can be kept in the rotation process of the rear driving wheel, tires are effectively prevented from making contact with the road surface in the rotation process of the rear driving wheel, driven high-frequency vibration is transmitted to the driving motor,and therefore the high-stability working efficiency of the driving motor is improved.

    本发明公开了一种电驱式电动汽车后驱动轮,其结构包括后拱架、活动弯杆、活动横架、线缆、后驱动轮、后桥横架、中心弹簧,本发明具有的效果:后桥横架两侧均安装有后驱动轮,且后桥横架与后拱架、活动弯杆和活动横架以及中心弹簧连接形成减振后悬架,且后拱架固定安装在汽车底盘上,因为后驱动轮通过驱动电机独立驱动,且在后驱动轮在形成独立减振结构和散热结构,能够在后驱动轮回转过程中保持驱动电机的稳定性以及散热效果,有效避免后驱动轮在回转中轮胎与路面接触,带动来的高频振动传递至驱动电机,从而提高驱动电机的高稳定性工作效率。
