The rear axle of electric vehicles belongs to the applied technology field of vehicles. It includes forming a shell cavity, one is located in the rear axle shell shell in the cavity and carry a big sprocket differential, a pair of their respective respectively and differential transmission at the end of the coupling and the other end of the respective respectively fixed with left and right wheels left and right half shaft, one end of the rear axle shell narrow indentation, and constitute the first pivot foot sprocket holes and for cavity; The other end is narrowed into a second pivot hole, and the two ends of the differential are arranged on the first and second pivot holes respectively. A pair of left and right half shafts are connected with the differential in a spline connection. The foot sprocket housing is provided with a foot sprocket for connecting with the differential.

Because this rear bridge can improve the adaptability of electric vehicles to road conditions, good operation and control effect, smooth driving and labor saving, conducive to increase safety, so that electric vehicles can improve the ability to climb and increase torque, energy saving, easy installation and processing with economic practicality.
