Description

Automatic clutch assembly

Technical Field

The utility model belongs to a clutch field for motorcycle transmission, concretely relates to automatic clutch subassembly.

Background

The double-clutch ball type automatic clutch applied to the motorcycle at present consists of an automatic clutch positioned at the output end of a crankshaft and a manual clutch positioned at the input end of a speed changer.

Along with the increase of the rotating speed of the automatic clutch at the crankshaft end, the steel balls move outwards along the slide rail through centrifugal force to tightly press the driving disc and the driven disc, power is transmitted by means of friction of the driving disc and the driven disc, when the rotating speed is reduced, the centrifugal force is reduced, the steel balls move centripetally along the slide rail, the pressing torque of the driving disc and the driven disc is reduced, and the pressing torque is gradually reduced until the power transmission is cut off. When the motorcycle is shifted, the manual clutch at the input end of the transmission needs to be operated to cut off or combine the power.

The automatic clutch with the structure mainly has the following two defects:

1. the crankshaft end automatic clutch can transfer small torque capacity, can be only used for a small-displacement low-power engine and cannot be used for a slightly large-displacement engine;
