The invention provides an electric wheel with a built-in suspension, and relates to the technical field of electric vehicles. A frame overhanging beam which is in rigid connection with a frame is adopted to replace a wheel axle of a traditional wheel, the suspension is internally arranged in the wheel, one end of the suspension is fixed to the frame overhanging beam, and the other end of the suspension is connected with a wheel rim of the wheel through a bearing; and a driving motor is installed on the frame overhanging beam, a rotor of the driving motor is connected with the wheel rim of the wheel through a flexible coupling, and torque transmission and wheel driving are achieved. According to the electric wheel with the built-in suspension, because an in-wheel suspension structure is adopted, the driving motor is installed on the frame overhanging beam, so that the mass of a wheel power device is transformed into the sprung mass portion of the suspension, and the problems that the suspension spring lower mass is increased, and the wheel dynamic response capability is poor due to the fact that a driving motor of an existing electric wheel increases the wheel mass are solved. The electric wheel with the built-in suspension can effectively improve the vehicle running stability and smoothness.
