The invention discloses a waved friction-driven side-hung self-adaptive automatic variable-speed driving assembly for an electric motorcycle. The waved friction-driven side-hung self-adaptive automatic variable-speed driving assembly comprises a box body, a transmission shaft, a slow-gear transmission mechanism and a mechanical intelligent self-adaptive variable-speed assembly; the box body is provided with a mounting part used for being mounted on the hub side in a side-hung manner; and the friction surface of a driving friction disc and the friction surface of a driven friction disc of the mechanical intelligent self-adaptive variable-speed assembly adopt waved friction surfaces to form a friction drive pair. According to the waved friction-driven side-hung self-adaptive automatic variable-speed driving assembly, the friction discs are adopted to form a separable and combinable structure to achieve the advantage of sensitive response, and the axial size is relatively small; meanwhile, as the structure that a ring-shaped bulge and a ring-shaped groove of the friction surfaces with the waved radial sections are mutually in embedded connection with each other is adopted, engagement of the friction surfaces is dispersed, the coaxiality of the driving friction disc and the driven friction disc is favorably guaranteed, the friction surfaces are favorably increased, and favorable transmission is ensured under the condition of limited elastic force; and the separation and combination sensitiveness is favorably guaranteed, the transmission precision is improved, and the waved friction-driven side-hung self-adaptive automatic variable-speed driving assembly is suitable for the field of electric motorcycles.
