The clutch on the motorcycle is an important part for transmitting or cutting off the output power of the engine, and the power output by the engine can be effectively transmitted to the wheels only through the clutch, so that the normal running of the motorcycle can be ensured. The main part in the motorcycle clutch is a central sleeve assembly, and a friction plate is arranged on the central sleeve assembly and is divided into an active friction plate and a passive friction plate. The clutch of the motorcycle generally comprises a plurality of driving friction plates and a plurality of driven friction plates which are arranged at intervals and are concentric circles. When the active friction plate and the passive friction plate are combined together under the action of the central sleeve, the cylindrical spiral spring and the pressure plate, the power of the engine is transmitted to the gearbox through the motorcycle clutch, and then the vehicle can be driven to run. When the pressure acting on the pressure plate is removed, the active friction plate and the passive friction plate are changed from a combined state to a separated state, the active friction plate rotates along with the engine, the passive friction plate rotates along with the active shaft of the speed changer, the power transmission is cut off, and the gear of the speed change mechanism can be switched under the condition of no load.
