The invention discloses an electric car wheel edge driving device. The electric car wheel edge driving device is characterized by comprising a motor and a wheel edge speed reduction device. The motor and the wheel edge speed reduction device are arranged inside a hub. The wheel edge speed reduction device comprises a sun wheel, a planet wheel, an inner gear ring and a planet carrier. The wheel edge speed reduction device is arranged inside a hub supporting piece. The inner gear ring is fixedly arranged inside the hub supporting piece. Due to the fact that the planet carrier is fixed to a steering knuckle, after a motor shaft drives the sun wheel to rotate, the hub supporting piece rotates along with the inner gear ring, and finally the hub supporting piece drives a wheel to rotate. According to the electric car wheel edge driving device, the motor and the wheel edge speed reduction device are integrated into the wheel, the axial size is decreased, and the space inside the wheel is sufficiently utilized, so that interference caused by the motor between a suspension and a steering mechanism during steering is lowered, the service life of a hub bearing is prolonged, and the car driving performance is optimized.
