  • Patent number: 6874607
    Abstract: A friction clutch with a pressure plate 6, which is mounted nonrotatably but with freedom of axial movement in a clutch housing 5, this pressure plate 6 being actuated by a pressure spring 7 in the direction toward a clutch disk 8, which can be clamped between the pressure plate 6 and an opposing pressure plate 1. More-or-less radially pretensioned friction springs 18 of a friction damping device are installed between the pressure plate 6 and a component with respect to which the pressure plate 6 can move in the axial direction. The friction springs 18 are mounted on spacer bolts 12, which project axially from the clutch housing 5, these bolts passing through corresponding openings 23 in a diaphragm spring, which serves as the pressure spring 7, the diaphragm spring being mounted on the spacer bolts 12 in such a way that its plane can be tilted.
