Abstract
The utility model relates to a wheel motor drive axle for an electric vehicle. The wheel motor drive axle for the electric vehicle comprises an axle case, a motor and a wheel reducer. A motor rotor and motor stators are arranged inside the axle case, the motor rotor is connected with a drive shaft of the motor, the drive shaft of the motor is connected with the wheel reducer through a differential axle, the wheel reducer is connected with a hub arranged on the axle case, and the hub is provided with tires. The wheel reducer comprises a sun wheel, a plurality of planet wheels and a planet carrier. The planet wheels are arranged outside the sun wheel and connected with the planet carrier, and the planet wheels and the sun wheel are fixed through gear rings. The sun wheel of the wheel reducer is connected with the differential axle, and the planet carrier of the wheel reducer is connected with the hub. The wheel motor drive axle for the electric vehicle has the advantages that due to the fact that parts such as a gearbox and a differential mechanism required by a centralized motor for driving the vehicle are eliminated, a drive system is simplified, the weight of the parts is lightened, and the arrangement of the whole vehicle is benefited.
