How does a car clutch work

When the driver steps on the clutch pedal, the clutch will temporarily separate the engine and the gearbox, and by cutting off the power between the two, the car can run smoothly and be at a standstill at any time.

Generally speaking, the clutch includes three working states, which are semi-linked when the owner steps on the clutch, does not step on the clutch, and partially steps on the clutch. Whenever the vehicle needs to start, the owner puts down the handbrake, and the clutch must be stepped on before the gear can be successfully engaged. At this time, the pressure plate of the clutch and the friction plate need to be separated, and the pressure plate will lean back. Keep rubbing and don't even touch anymore. On the contrary, when the vehicle is running on the road normally, the relationship between the pressure plate and the friction plate is intimate, and the pressure plate will be tightly attached to the friction plate. At this time, the two will run friction, and the friction force is also the largest in all states. When the clutch is in a semi-linked state, the clutch and the friction plate are in a sliding friction motion, and its speed is relatively fast, which transmits power to the vehicle gearbox through friction. Because the clutch relies on friction to transmit power and torque, it will be overloaded when transmitting power. In order to avoid accidents, the clutch has an automatic slip function to prevent transmission overload due to excessive load.
