Clutch and its release drive: 1 - driven disk; 2 - clutch cover with pressure plate; 3 - clutch release bearing; 4 - clutch release cable; 5 - clutch pedal; 6 - clutch release fork
The clutch is used for short-term disconnection of a running engine from the gearbox and drive wheels and its smooth connection at the moment of starting the car, as well as for shifting gears in the gearbox while driving. Additionally, the clutch serves to protect parts of the engine and gearbox from overloads that occur in certain driving situations (hard braking or acceleration). The clutch is installed only on vehicles with a manual transmission.
Clutch drive cable with automatic adjustment of the gap that occurs when the friction linings are worn.
Dry single-disc clutch with central pressure spring diaphragm type. Structurally, the clutch consists of a clutch cover with a pressure plate, a driven disc and a clutch release mechanism. The driven disk with a spring damper is put on the splines of the input shaft of the gearbox. The diameter of the driven disc is 200 mm. The disc includes two friction linings, the thickness of which in the compressed state is 6.8 mm.
When the clutch pedal is depressed, the force is transmitted through the cable drive to the clutch release lever, as a result of which the clutch release bearing located in the clutch moves, which compresses the central part of the diaphragm spring. The outer ends of the spring take the pressure plate away from the lining of the driven disc and the latter moves away from the flywheel. The clutch is disengaged and the rotation of the crankshaft is not transmitted to the gearbox.
When the pedal is released, the pressure plate again presses the driven plate against the flywheel. Now the rotation from the flywheel through the hub of the driven disk is transmitted to the input shaft of the gearbox.
