Internal rotor concave-convex friction driven adaptive automatic transmission driving assembly of electric motorcycle

The invention discloses an internal rotor concave-convex friction driven adaptive automatic transmission driving assembly of an electric motorcycle. The driving assembly comprises an internal rotor driving motor, a box body and a transmission shaft, and further comprises a slow gear transmission mechanism and a mechanical intelligent adaptive variable speed assembly which is arranged on the transmission shaft, wherein a friction surface of a driving friction disc and a friction surface of a driven friction disc of the mechanical intelligent adaptive variable speed assembly form a friction transmission pair with friction faces nested to each other in a concave-convex manner. By adopting the detachable structure of the friction discs, the driving assembly has the advantage of being sensitive response and small in axial dimension. At the same time, by adopting the radial section concave-convex embedded structure of the friction surfaces, engagement of the friction surfaces is ensured under the condition with limited radial size. The coaxiality of the driving friction disc and the driven friction disc can be ensured, the friction surface area can be enlarged, so that good transmission can be ensured under the condition with limited elasticity. Besides, sensitivity of disengagement and engagement can be ensured and the transmission precision can be improved. The driving assembly is applicable in the field of electric vehicles.
