The invention discloses a magneto-rheological torsion damper of an electric wheel. The magneto-rheological torsion damper comprises a motor rotor capable of being connected with a power output end ofa hub motor and a hub rotor capable of being fixed to a hub. The motor rotor comprises a motor rotor connecting disc; motor rotor shaft teeth are arranged on a circumferential side surface of the motor rotor connecting disc at intervals; the hub rotor comprises a hub rotor ring and hub rotor shaft teeth arranged on the circumferential inner surface of the hub rotor ring at intervals; and the hub rotor shaft teeth are arranged between two adjacent motor rotor shaft teeth, connecting springs are fixed between the side surfaces of the motor rotor shaft teeth and the side surfaces of the hub rotorshaft teeth adjacent to the motor rotor shaft teeth, and a magneto-rheological fluid is arranged in a space formed by the motor rotor shaft teeth and the hub rotor shaft teeth in a closed mode. Through relative rotation of the hub rotor and the motor rotor, the magneto-rheological fluid generates a damping force opposite to the torque fluctuation of a hub shaft, and influence of wheel bounce andimpact on normal work of a speed reducer and the motor is reduced.
