The clutch basket contains a release fork. It has a release bearing that does not require maintenance, which presses the driven clutch disc when the clutch is released. In a hydraulic control system, the release fork is connected to the piston of the hydraulic system's working cylinder. The working fluid of the hydraulic clutch control system is brake fluid, which is poured into a separate compensation tank.
When released, the driving disk presses the driven disk through membrane springs to the engine flywheel and thus ensures the transmission of torque from the engine to the gearbox.
When the clutch pedal is pressed, the piston rod in the primary clutch cylinder creates pressure, which is transmitted through the hydraulic pipeline to the clutch slave cylinder fixed to the gearbox. The piston of the slave cylinder, overcoming the force of the spring of the leading disk, presses the release bearing through the clutch fork, slightly displacing the leading disk. Due to this, the slave disk, located between the leading clutch disk and the engine flywheel, is released.
With a mechanical clutch, the clutch pedal is connected to the clutch release lever via a clutch cable.
