The clutch performs two tasks in a car: when a gear is engaged, it breaks the power circuit between the engine and the gearbox, and when the car is moving, it ensures smooth power engagement.
The clutch consists of a pressure plate, a driven clutch plate and a clutch release bearing.
The clutch pressure plate is firmly mounted on the flywheel, which in turn is attached to the engine crankshaft. Between the pressure plate and the flywheel is a driven disk, which is pressed against the flywheel by the pressure plate. The driven disk is centered on the splines of the associated transmission drive shaft.
When pressing the clutch pedal (disengaging the clutch) the force is transmitted through a hydraulic or mechanical drive and through a lever to the clutch release bearing, which is pressed against the diaphragm spring of the pressure plate and moves it slightly. Due to this, the driven clutch plate moves away from the flywheel and no longer presses the driven disk against it, while the power engagement between the engine and the gearbox is broken.
Attention: In some vehicles with engines with a displacement of 1.8 liters, the clutch is driven by cable traction. On other car models, a hydraulic clutch drive is installed: the piston of the working cylinder of the hydraulic system is attached to the pressure lever.

When the clutch pedal is pressed, pressure is created in the slave cylinder located in the footwell, which is transmitted via a hydraulic line to the slave cylinder mounted on the clutch housing. The piston of the slave cylinder presses the bearing against the diaphragm spring of the pressure plate through the clutch release fork and moves it slightly.
The hydraulic system uses brake fluid supplied from a common brake fluid expansion tank.
If the clutch pedal is released (clutch engaged), the pressure plate presses the driven disk against the flywheel, and the power circuit is closed again, since the pressed driven disk is firmly connected through splines to the drive shaft of the gearbox.
Each time the clutch is engaged and disengaged, the friction linings of the driven disc wear out as a result of minor slippage. The driven clutch disc is therefore a wearable component, the service life of which, however, is over 100,000 km. The wear rate depends mainly on the load (operation of a vehicle with a trailer) and driving mode. The clutch does not require maintenance, as it has automatic adjustment.
