Background
The clutch piston is an important component for clutch power transmission, and is used for realizing the engagement and separation of a clutch friction plate and a steel sheet and controlling the power transmission. When the piston is combined with the piston cover, the spring assembly and the main rotating hub, oil is filled in the pressure cavity, pressure is applied to the piston to enable the piston to axially displace, and the friction plate and the steel plate are pushed to be combined; when the piston is separated, the oil is removed from the pressure cavity, and the compressed return spring acts to enable the piston to return to the original position, so that the friction plate is separated from the driving part.
The existing clutch piston is generally integrated, and when the friction surface of the piston is damaged, the whole piston is often required to be replaced, so that the maintenance cost is high; when the piston compresses the spring, the gap between the cylinder and the clutch base is easy to be increased due to the elasticity of the spring, so that the clutch is unstable in operation.
