Abstract
The invention relates to a clutch for a motorcycle. The clutch comprises a driving disc connected with an engine, a driven disc connected with a gearbox, a clutch shell connected with the driving disc, a driving friction plate and a driven friction plate which are used for transmitting torque and a pressing disc arranged on the outer side of the driven disc. The driven disc is divided into an outer side driven disc body and an inner side driven disc body in a split manner. The driving friction plate and the driven friction plate are arranged between the outer side driven disc body and the inner side driven disc body. Wedge-shaped blocks are arranged on the outer side driven disc body and wedge-shaped holes or wedge-shaped grooves matched with the wedge-shaped blocks are formed in the inner side driven disc body; or the wedge-shaped blocks are arranged on the inner side driven disc body and the wedge-shaped holes or the wedge-shaped grooves matched with the wedge-shaped blocks are formed in the outer side driven disc body.
