Abstract
Friction clutch, in particular for motor vehicles, consisting of a driving portion as a counterpressure plate, a pressure plate oriented so that it can move axially but not rotationally with respect to the counterpressure plate, a clutch plate with clutch linings which can be fixed between the two and which is located non-rotationally on a drive shaft, whereby the clutch plate is provided if necessary with a load and/or idle damper, whereby there are also pressure elements for the clutch plate and/or the damper. On such a friction clutch, the object of the invention is to realize different, predetermined moments of friction with the identical geometry of the friction device. The invention teaches that this object can be achieved by providing as the pressure element at least one permanent magnet and/or at least one magnet system and/or at least one electrically energized magnetic circuit.
