What is the function of a car clutch?

[DiMartin]

The functions of a car clutch: 1. Gradually engage the engine with the transmission system to ensure smooth vehicle starting; 2. Temporarily cut off the engine's power transmission to ensure smooth gear shifting; 3. Limit the transmitted torque to prevent overload of the transmission system; 4. Reduce torsional vibration impact. The clutch consists of friction plates, spring plates, pressure plates, and a power output shaft, and is located between the engine and the gearbox. It is used to transmit the torque stored on the engine flywheel to the gearbox, ensuring that the vehicle delivers an appropriate amount of driving force and torque to the drive wheels under different driving conditions, belonging to the powertrain category. During semi-engagement, the clutch allows a speed difference between the power input end and the power output end, which means it transmits an appropriate amount of power through this speed difference.
