The clutch consists of pressure and driven discs, as well as a hydraulic drive with master and slave cylinders.
Clutch components
The pressure plate is bolted to the flywheel connected to the crankshaft of the engine. Between the pressure plate and the flywheel is a driven disk, which is pressed against the flywheel by the thrust bearing of the slave cylinder. The driven disk is connected to the manual transmission input shaft through a spline connection.
When the clutch pedal is depressed, the brake fluid from the common reservoir is transferred under pressure through the clutch master cylinder to the slave cylinder (CSC). The thrust bearing of the slave cylinder acts on the pressure plate. In this case, the driven disk is retracted from the flywheel and the power connection between the engine and the manual transmission is interrupted. When released, the pressure spring presses the bearing against the diaphragm spring of the pressure plate. This reduces wear on the clutch thrust bearing, as when turned on, it does not accelerate to the engine speed. Clutch adjustment is not required.
Each time the clutch is engaged and disengaged as a result of force action, the friction linings of the driven disk are worn. The driven disc is a wear part, but its average life is quite long and depends mainly on the load on the engine and driving style.
