The invention discloses a concave-convex type friction drive side hanging type self-adaption automatic variable speed drive assembly of an electric motor car. The concave-convex type friction drive side hanging type self-adaption automatic variable speed drive assembly comprises a box body, a transmission shaft, a slow gear transmission mechanism and a mechanical intelligent self-adaption variable speed assembly. The box body is provided with a mounting portion for being arranged on the wheel hub side in a side hanging mode. A concave-convex embedded friction surface friction drive pair is adopted for the friction surface of a drive friction disc and the friction surface of a driven friction disc of the mechanical intelligent self-adaption variable speed assembly. A separation and combination structure is formed through the friction discs, the automatic variable speed drive assembly has the advantages of being sensitive in reaction and small in axial size; meanwhile, the concave-convex embedded structures of the radial sections of the friction surfaces are adopted, joint of the friction surfaces is guaranteed under the condition of limited radial size, guarantee of the coaxiality of the drive friction disc and the driven friction disc is facilitated, increase of the friction surfaces is facilitated as well, and it is guaranteed that good transmission is kept under the condition of limited elastic force; flexibility of separation and combination is further facilitated, transmission accuracy is improved, and the automatic variable speed drive assembly is applicable to the field of electric vehicles.
