Diaphragm Clutch

 
 
 

Dr. Ing. Georg Schaeffler and Dr. Wilhelm Schaeffler founded LuK in 1965 with the objective of supplying diaphragm clutches for the successor to the VW Beetle. LuK was the first clutch manufacturer to introduce the diaphragm clutch in Europe. Today, one in three news car rolling off the production line is fitted with an LuK clutch.

Due to the further developments in vehicle construction, clutch components must now fulfil a large number of requirements that mainly affect driving comfort, such as rapid gearshift, vibration damping and minimisation of noise. Modern clutches are characterised principally by high speed performance, high transmission reliability, low section height, low release forces and long service life.

As early as the 1970s, Schaeffler developed the diaphragm clutch, which successively and continuously displaced coil springs from the car sector. The contact force for transmitting the engine torque is now provided by the slotted disc spring. This gives the driver significantly more driving comfort since, due to the lower release force, he only needs to apply a significantly lower pedal force. According to the construction and operating method of the clutch, a distinction is drawn between the drawn and compressed diaphragm clutch.
