The invention relates to an electric wheel independent suspension device which comprises a hydro-pneumatic spring, an energy accumulator, a motor, a wheel, a steering swing arm and an electric push rod, the hydro-pneumatic spring comprises a cylinder barrel and a piston rod, the cylinder barrel is fixed to a frame, a rectangular sliding way is arranged in the piston rod, and a steering transmission shaft penetrating through the tops of the cylinder barrel and the piston rod is arranged in the cylinder barrel and the piston rod; the steering transmission shaft is in rotary sealing fit with the top of the cylinder barrel and in sliding sealing fit with the top of the piston rod, a rectangular sliding block matched with the rectangular sliding way is fixed to the lower end of the steering transmission shaft, and the energy accumulator is fixed to the frame and communicated with a hydraulic working cavity of the hydro-pneumatic spring through an oil pipe. The wheels are fixed to output shafts of the motors, one end of the steering swing arm is fixedly connected with the steering transmission shaft, the other end of the steering swing arm is hinged to a telescopic rod of the electric push rod through a first pin shaft, and a cylinder body of the electric push rod is hinged to the frame through a second pin shaft. The system has the advantages of being simple in structure, high in integration level, strong in functionality and wide in application range.
