General description
The clutch consists of a friction plate, a pressure plate assembly, a release bearing and a release lever. All of these components are housed in a large, aluminum alloy clutch housing sandwiched between the engine and transmission. Release mechanism with cable drive.
The friction disc is mounted between the engine flywheel and the clutch pressure plate and can slide freely on the grooves of the transmission input shaft.
The pressure plate assembly is bolted to the flywheel. When the engine is running, drive from the crankshaft is transmitted through the flywheel to the friction disc (these components are securely pressed together by the pressure plate assembly) and further, from the friction disc to the input shaft of the transmission.
To interrupt the transmission of torque, it is necessary to remove the pressure of the compression spring from the friction disc. Depressing the clutch pedal pulls the drive cable, which turns the clutch release fork. The fork presses the thrust bearing against the sectors of the diaphragm spring. Due to this, the peripheral part of the spring moves away from the friction disc, thus relieving pressure from it and disengaging the clutch.
When the pedal is released, the diaphragm spring moves the pressure plate back and the friction plate is pressed against the flywheel, resuming the transfer of power from the transmission motor.
The increase in clearance caused by wear on the clutch friction disc linings is automatically compensated by the adjuster attached to the clutch pedal. The automatic regulator consists of a gear segment, a latch and a spring. One end of the clutch cable is attached to a toothed segment that rotates freely on the pedals but is held in tension by a spring. When the pedal is depressed, the latch comes into contact with the toothed segment, blocking it and allowing the clutch to be controlled. As soon as the pedal is released, the spring causes the toothed segment to move away from the latch and turn slightly, thus compensating for cable play.
Some late models may be equipped with an automatic clutch that engages when the gear lever is pressed. At the time of writing this manual, manufacturers have not provided any data regarding this type of clutch.
