A clutch system is a mechanical device used in vehicles to connect and disconnect the engine from the transmission. This allows the driver to change gears smoothly without damaging the engine or transmission. When the clutch pedal is pressed, the clutch disengages, enabling the driver to shift gears. There are different types of clutch systems, including manual clutches and automatic clutches. Manual clutches require the driver to operate the pedal, while automatic clutches engage and disengage automatically based on the vehicle's speed and load. Both systems play a crucial role in the overall performance and drivability of a vehicle.
