What are the classifications of clutch operating mechanisms?

[WalkerLee]

The classifications of clutch operating mechanisms are: 1. Mechanical operating mechanism; 2. Hydraulic operating mechanism; 3. Pneumatic-assisted hydraulic operating mechanism. The functions of an automotive clutch are: 1. Ensuring smooth vehicle starting; 2. Facilitating gear shifting; 3. Preventing overload of the transmission system; 4. Reducing torsional vibration impact. The maintenance methods for the clutch master cylinder are: 1. Inject hydraulic oil into the cylinder; 2. Loosen the bleeder bolt and push the piston to allow air inside the cylinder to escape; 3. Tighten the bleeder bolt. The working principle of an automotive clutch is that the torque generated by the engine is transmitted to the driven plate through the friction between the flywheel, pressure plate, and the contact surface of the driven plate. When the driver depresses the clutch pedal, the diaphragm spring's large end moves the pressure plate backward via mechanical transmission, causing the driven part to separate from the driving part.
