Abstract
A friction clutch with a pressure plate, which is mounted nonrotatably but with freedom of axial movement in a clutch housing, this pressure platebeing actuated by a pressure springin the direction toward a clutch disk, which can be clamped between the pressure plateand an opposing pressure plate. More-or-less radially pretensioned friction springsof a friction damping device are installed between the pressure plateand a component with respect to which the pressure platecan move in the axial direction. The friction springsare mounted on spacer bolts, which project axially from the clutch housing, these bolts passing through corresponding openingsin a diaphragm spring, which serves as the pressure spring, the diaphragm spring being mounted on the spacer boltsin such a way that its plane can be tilted.
