Abstract
A friction clutch having a diaphragm spring formed with a ring-shaped base and tabs extending radially inwardly from the base and separated by slots from one another. The slots terminate radially outwardly in hole-like cutouts and the disc spring is tiltably supported on a part of the clutch and is clamped between a first roll-off support at the clutch part and a substantially circular discrete second roll-off support at the side of the disc spring facing away from the clutch part. The second roll-off support is acted upon by the spring when the clutch is disengaged and the first roll-off support is acted upon by the spring when the clutch is engaged. Holding means secure the second support to the clutch part, and the second roll-off support engages the spring radially outwardly of the cutouts and is formed, in the vicinity of each of the cutouts, with an interruption extending along at least 50% of the length of the respective cutout, as considered in the circumferential direction clutch.
