The invention discloses an electric motor car external rotor electric machine concave-convex friction drive self-adaption automatic transmission drive assembly comprising an external rotor drive motor, a box body, a transmission shaft, a slow shift transmission mechanism, and a machinery intelligent self-adaption transmission assembly arranged on the transmission shaft; a friction surface of an active friction plate and a friction surface of a passive friction plate of the machinery intelligent self-adaption transmission assembly employ a friction transmission pair having concave-convex embedded friction surfaces; the friction plate separation-combination structure is employed, so the assembly is flexible in reaction, and small in axially size; in addition, radial sections of the friction surfaces are mutually embedded in a concave-convex manner, so the joint of the friction surfaces can be ensured under limited radial size conditions, thus ensuring coaxiality of the active and passive friction plates, enlarging friction areas, and ensuring excellent transmission under limited elastic conditions; the electric motor car external rotor electric machine concave-convex friction drive self-adaption automatic transmission drive assembly is flexible in separation and connection, can improve transmission precision, and is suitable for the electric vehicle field.
