The invention provides an electric vehicle wheel driving device and a vehicle with the wheel driving device. The electric vehicle wheel driving device comprises a hub motor, a first constant velocity universal joint, a transmission shaft, a second constant velocity universal joint, a transmission short shaft, a connecting disc, a flange disc and a brake. The brake is connected with the hub motor sequentially through the connecting disc, the transmission short shaft, the second constant velocity universal joint, the transmission shaft and the first constant velocity universal joint; the brake and a component of the brake are moved out of the hub motor, and unsprung mass is converted into sprung mass, so that the structure of the hub motor is greatly simplified; heat dissipation of the brake is facilitated, the influence of brake heat on a permanent magnet is removed, the service life of the motor is prolonged, and the unsprung mass of the vehicle is reduced; the device is very beneficial to failure rate reduction, the manufacturing cost of the hub motor can be reduced, and driving smoothness and operation stability of the electric vehicle are improved.
