From clutch cable to CSC:

Clutch actuation systems for passenger cars.

The clutch actuation system transfers the pressure of the driver’s foot on the pedal to the clutch in order to disengage it. It has to ensure absolute reliability, meet ergonomic requirements, and provide a high level of comfort throughout its entire service life. The actuation system includes the hydraulic transmission path with master and slave cylinder as well as the mechanical part with clutch release bearing and lever.

Clutch actuation system with cable control

Function of the clutch actuation system with cable control

The pedal motion is transferred to a steel cable (1), the release fork (2) and the clutch release bearing (3) so that the clutch is actuated. The highlighted areas show wearing zones in the clutch environment.

Conventional master/slave cylinder

Function of the master/slave cylinder

The pedal motion is transferred to a hydraulic cylinder (1, master) located directly below the pedal. In a closed system, the cylinder generates hydraulic pressure that is absorbed by a slave cylinder (3) via a hose assembly (2).

Concentric slave cylinder (CSC)

Function of the concentric slave cylinder (CSC)

The concentric slave cylinder (1) merges the clutch release bearing and the slave cylinder to form one unit. This offers clear advantages over mechanical-hydraulic systems.

If the concentric slave cylinder is not replaced together with the clutch, this leads to increased wear.

Therefore, always replace the concentric slave cylinder together with the clutch.

High-quality SACHS clutch cables

With its high-quality clutch cables, SACHS covers the European vehicle market almost completely. Clutch cables are subject to high mechanical stress. The first indications of wear are increased physical effort and noises when actuating the clutch, or clutch slipping and grab.
