Clutch disengagement process
The force of the sensor plate spring
counteracts that of the main diaphragm spring
and is rated such that the main diaphragm
spring is pressed against the adjusting ring
under normal releasing load.
If the force of the main diaphragm spring (also
refer to load diagram) is greater than that of
the sensor plate spring, the main plate spring
will not come into contact with the adjusting
ring.
The compression springs rotate the adjusting
ring along the ramps in the housing cover.
In this way, lining wear is compensated and
the forces are again equalised.
