The clutch has a traditional design with a single damped drive plate and a self-adjusting clutch cover diaphragm spring, hydraulically actuated by the clutch pedal.
When the clutch pedal is depressed, pressure is generated that acts on the hydraulic fluid in the master cylinder. The pressure of the working fluid is transmitted through the pipeline from the master cylinder to the working cylinder in the gearbox. Fluid pressure actuates the slave cylinder, which in turn pushes the fingers on the clutch cover, releasing the drive plate and disengaging the engine crankshaft from the gearbox.
The hydraulic clutch purge adapter is located at the front of the transmission. The adapter provides a connection between the pressure line from the master cylinder to the slave cylinder. The adapter has a screw that serves to remove air from the hydraulic clutch system after replacing one of the hydraulic elements during maintenance. In addition, the adapter has a peak torque limiter. It prevents instantaneous engagement of the clutch if the driver accidentally releases the clutch lever, eliminating possible damage to transmission components.
Vehicles equipped with the system «Stop/Start» - starting from MY 2010
A linear clutch sensor, located in the clutch master cylinder and hardwired to the central junction box, is used to determine the position of the clutch pedal. It is used in conjunction with other sensor outputs to restart the engine, stop it, or restart it after the engine has stalled on vehicles with «Stop/Start». It is also used with the 1st and Reverse switches to test the plausibility of the clutch signal.
The clutch pedal position sensor receives information about the position of the clutch pedal from a magnet in the clutch master cylinder. Therefore, in case of replacement of the master cylinder, it must be correctly selected and installed. For more information, see the chapter: Starting system (303-06C Starting system - 2.2L Duratorq - Td4, Vehicles built from 03/2009, Description and function).
