What drives the clutch disc in a vehicle?

The clutch disc in a vehicle is driven by the engine flywheel when the clutch pedal is released. When the driver releases the clutch pedal, the pressure plate applies force to the clutch disc, pressing it against the flywheel. This contact transfers power from the engine to the transmission, enabling the vehicle to move.

The function of the clutch is to engage and disengage the engine from the transmission. When the clutch pedal is pressed, the pressure plate moves away from the clutch disc, separating it from the flywheel to disengage the engine's power. Conversely, when the pedal is released, the pressure plate applies pressure to the disc, allowing it to engage with the flywheel and transmit torque.

This process is fundamental for smooth shifting and vehicle operation, providing the necessary control for the driver. This operation ensures that the vehicle can start and stop without stalling the engine, and allows for gear changes without grinding or damaging the transmission.
