What are the types of clutch operating mechanisms?

[VanCorey]

Clutch operating mechanisms can be divided into two types: manual and pneumatic-assisted. The manual type uses the driver's foot pedal force as the sole power source, while the pneumatic-assisted type primarily utilizes compressed air generated by an engine-driven air compressor as the main power source, assisting the manual operation of the clutch. The manual operating mechanism can be further categorized into mechanical and hydraulic types. The clutch operating mechanism is a set of components that disengages the clutch and allows for smooth engagement, including all parts and mechanisms from the clutch pedal to the release bearing. It starts at the clutch pedal inside the cab and ends at the release bearing inside the clutch, converting the manual force on the pedal into thrust to push the release sleeve.
