Clutch — General Information (Mercedes-Benz S-Class W140)

The clutch is designed (in general) for short-term disconnection of the engine shaft from the transmission, as well as their subsequent smooth connection, which is necessary when starting the car from a standstill and when changing gears while driving.

The clutch consists of a leading part, the parts of which are connected to the engine crankshaft, and a driven part, the parts of which are connected to the transmission, as well as elements that engage and disengage the clutch. The driven part is disconnected from the leading part when the clutch is disengaged, which is carried out using the clutch release drive.

Mercedes S-class (W140) vehicles are equipped with a dry single-plate clutch with a central diaphragm spring.

The leading elements of the clutch are the flywheel, the pressure plate and the clutch basket, which is bolted to the flywheel. The driven element is the clutch disc with friction linings and a splined sleeve, thanks to which the disc is able to slide freely along the splines of the drive shaft of the gearbox and rotate it. The driven and leading elements are held in contact by the force of a diaphragm spring. This force is created in the assembly of the pressure plate and the clutch basket.
