Structure and function of clutch plates
2025-06-30
Composition
Clutch plates are typically composed of friction material, a steel plate base, and rivets. The friction material (such as asbestos-based, semi-metallic, or ceramic fiber) provides friction, the steel plate base ensures strength, and the rivets secure the friction material.
Working Principle
Power Transmission: When the driver depresses the clutch pedal, the pressure plate separates from the flywheel, the clutch plates are no longer compressed, and power transmission is interrupted.
Power Disengagement: After releasing the pedal, the pressure plate presses the clutch plates against the flywheel under spring action, transmitting power to the gearbox through friction.
Semi-engaged State: When the clutch is partially depressed, there is sliding friction between the friction plates and the flywheel, allowing for smooth starting or shifting.
