What are the four main components of a clutch?

[MacLucas]

A clutch is basically composed of the following four parts: 1. Driving part: flywheel, clutch cover, pressure plate. 2. Driven part: driven plate, driven shaft. 3. Compression mechanism: compression spring. 4. Operating mechanism: clutch pedal, release rod, release fork, release sleeve, release bearing, release lever, etc. Here are the relevant introductions: 1. Working principle of the clutch: The engine flywheel is the driving part of the clutch, and the driven plate with friction lining and the driven hub are connected to the driven shaft through sliding splines; the compression spring presses the driven plate against the flywheel end face. The engine torque is transmitted to the driven plate through the friction between the flywheel and the driven plate contact surface, and then transmitted to the driving wheel through the driven shaft and a series of components in the transmission system; the greater the compression force of the compression spring, the greater the torque the clutch can transmit. 2. Function of the clutch: Since the car needs to maintain power transmission frequently during driving, and the interruption of transmission is only a temporary need, the driving part and the driven part of the car clutch are often in the engaged state.
