Function of SAC clutch
Compared to a conventional clutch, the
following parts are new or modified:
• Sensor plate spring
• Adjusting ring with ramps (wedges) and
compression springs
• Housing cover with ramp indentations and
guides for the compression springs
• Stop for release travel (integrated in the
housing cover)
• Auxiliary spring (riveted to the housing
cover)
The
stop for release travel
limits the
travel of the release bearing and
prevents unintentional adjustment of
the adjusting ring.
The
auxiliary spring
counteracts the
main plate spring as of a defined
travel distance and ensures an even
force curve during clutch engagement
and disengagement.
