How the clutch works
1)Jointed state
When the clutch is in the engaged state, each component of the operating mechanism returns to their respective positions under the action of the return spring, and the inner end of the separation lever
There is a certain gap between the release bearing and the compression spring to compress the flywheel, driven plate and pressure plate together. The engine torque passes through the flywheel and pressure plate through the friction between the two friction surfaces of the driven plate. It is transmitted to the driven plate and then input to the transmission by the driven shaft.
2)Separation process
When disengaging the clutch, the driver depresses the clutch pedal, and the release sleeve and release bearing are pushed by the release fork to first eliminate the gap between the release bearing and the inner end of the release lever, and then push the inner end of the release lever forward, causing the release lever to move forward. The outer end drives the pressure plate to move backward against the force of the compression spring, the friction disappears, the main and driven parts of the clutch separate, and the power transmission is interrupted.
3)Joining process
When engaging the clutch, the driver slowly lifts the clutch pedal. Under the action of the compression spring, the pressure plate moves forward and
Gradually tighten the driven plate, so that the pressure between the contact surfaces gradually increases, and the friction torque also gradually increases; when the flywheel, pressure plate and driven plate
When the coupling between the moving plates is not tight, the friction torque that can be transmitted is small, and there is a speed difference between the main and driven parts of the clutch.
The clutch is in a slipping state; as the clutch pedal is gradually lifted, the degree of compression between the flywheel, pressure plate and driven plate
Gradually, the rotational speeds of the main and driven parts gradually become equal, until the clutch is fully engaged and stops slipping.
Finish.
