The present invention discloses a spiral disc type friction transmission self-adaption automatic speed change drive assembly for an electric motor car. The spiral disc type friction transmission self-adaption automatic speed change drive assembly comprises a box body, a transmission shaft, a slow gear transmission mechanism, and a mechanical intelligent self-adaption speed change assembly by utilization of disc type friction transmission; and the slow gear transmission mechanism comprises an overrunning clutch, an inner ring of the overrunning clutch sleeves a transmission shaft sleeve, and an inner circle of the inner ring is provided with a spiral cam used for being cooperated with the transmission shaft sleeve. The spiral cam output structure is adopted by the inner ring of the overrunning clutch, the spiral cam is disposed on the transmission shaft sleeve, use of end cams is reduced, and the spiral cam has good flexibility and is sensitive to resistance. The overrunning clutch has the possibility of multiple cam transmission, sensibility and stability of disengaging and engaging of friction transmission are ensured by utilization of the disc type friction transmission, axial dimension of a speed changer is reduced, and the spiral disc type friction transmission self-adaption automatic speed change drive assembly is suitable for hubs and has relatively good flexibility and high transmission precision during the speed change process.
