Wear indicator for friction clutches

A friction clutch, comprising:

• a clutch case;
• a pressure plate;
• a clutch housing;
• tangential leaf springs that connect said pressure plate to said clutch housing so that said pressure plate is axially displaceable and fixed with respect to rotation relative to said clutch housing;
• two sheet metal structural component parts that can be clamped against one another, one of said structural component parts being movable in a radial direction, clamping of the parts being cancelled when said wear limit is reached so that said movable structural component part springs into a new radial position and remains in said new radial position, one of said moveable structural component part is a spring clip having a finger and a flag, said finger projects toward a flywheel and said flag extends essentially perpendicular to said finger, said finger being configured to run against the flywheel when the wear limit is reached so that said clamping cancels, said clip springs back and said resulting radial position of said flag can be detected;
• rivets arranged to connect the tangential leaf springs to the clutch housing and the pressure plate, one of the rivets also fastening the two structural component parts to one of the pressure plate and the clutch housing;
• and
• a sensor arranged inside of said clutch case for detecting said flag.
