Abstract:
A friction clutch includes a housing, an axially displaceable pressure plate, a lever system for displacing the pressure plate, a ramp system arranged between the pressure plate and the lever system, a torsion device for rotating the ramp system, and a control device. The torsion device has a spindle to drive the ramp system and a drive gear with an external profile. The control device has a fastening portion fixed to the housing and a pawl with a plurality of tongues to forming a positive interlock. At least one tongue is arranged to engage the external profile. Each tongue is separated from another tongue by a gap extending in the axial direction. At least one gap, starting from a tip of the tongue, extends in the axial direction 30% or less of a minimum distance between the tip and the fastening portion.
