The clutch of a car is severely worn. When the driver steps on the clutch pedal, the active and passive parts of the clutch diaphragm spring cannot separate independently through the transmission of mechanical components. The wear of the clutch is also accompanied by a burnt smell, abnormal noise, slipping, and difficulty shifting.

       The clutch is a machine located between the engine and the gearbox, and the output shaft of the clutch is the input shaft of the gearbox. The requirements for clutches in automobiles include quick disengagement, smooth connection, and sufficient heat dissipation function. During the driving process of a car, the driver controls the clutch pedal to separate and connect the engine and clutch, thereby cutting off and transmitting the power input from the engine to the transmission. All cars are equipped with a clutch, which is an assembly that connects the car's transmission system with the engine system. It reduces the impact of gear shifting during the use of the car and provides protection for the engine.
