The invention discloses a rear axle driving device for the low-speed four-wheel electric vehicle. The device comprises a vehicle body, the vehicle body is provided with a vehicle frame, and two front wheels and two rear wheels are installed on the vehicle frame; two half shafts are arranged in the frame, and one half shaft corresponds to one rear wheel; a rear axle driving device is arranged in the frame and is in transmission connection with the half shaft; the rear axle driving device comprises a driving motor arranged in the frame, and the driving motor is in transmission with the rear wheels through a transmission belt or a gear; an electromagnetic brake device is mounted in the frame and corresponds to the end parts of the inner sides of the two half shafts; and the electromagnetic brake device and the driving device are jointly connected with a controller. A differential mechanism does not need to be used, the cost of the low-speed four-wheel electric vehicle is reduced, the weight of the four-wheel electric vehicle is greatly reduced, and an ideal rear axle driving mode is achieved.
本发明公开了一种低速四轮电动车辆用后桥驱动装置,包括车本体,车本体有车架,车架上安装有有两个前轮和两个后轮;所述车架内设置有两根半轴,一根半轴对应一个后轮;所述车架内设置有后桥驱动装置,后桥驱动装置传动连接半轴;所述后桥驱动装置包括设置在车架内的驱动电机,驱动电机通过传动带或齿轮与后轮进行传动;所述车架内安装有电磁刹车装置,电磁刹车装置对应两根半轴的内侧端部;所述电磁刹车装置和驱动装置共同连接有控制器。本发明无需使用差速器,降低了低速四轮电动车辆的成本,并且大大降低了四轮电动车辆的重量,是一种理想的后桥驱动方式。
