The invention discloses a self-adaptive automatic speed change drive assembly adopting spiral wavy friction transmission for an electric motorcycle. The self-adaptive automatic speed change drive assembly comprises a box body, a transmission shaft, a slow-gear transmission mechanism and an intelligent mechanical self-adaptive speed change assembly adopting wavy friction transmission. According to the slow-gear transmission mechanism, the inner ring of an overrun clutch is sleeved with a transmission shaft sleeve and the inner circle of the inner ring is provided with a spiral cam matched with the transmission shaft sleeve. An output structure of the spiral cam is adopted in the inner ring of the overrun clutch and arranged on the transmission shaft sleeve, so that an end face cam is omitted, and the spiral cam is good in smoothness and can sensitively make a response to resistance; and multi-cam transmission is possible for the overrun clutch, wavy friction transmission is adopted for guaranteeing flexibility and stability of disengagement and engagement of friction transmission, the axial size of a speed changer is reduced, the drive assembly is suitable for hubs and the like, and good smoothness and high transmission accuracy are acquired in the speed change process.
