Abstract: A pressure plate assembly for a friction clutch includes a housing connectable with an abutment arrangement for rotation therewith about an axis of rotation. The housing has an outer axial side and an inner axial side. A pressure plate is mounted in the housing so that it faces the inner axial side. The pressure plate is rotatable with the housing about the axis of rotation. The pressure plate includes actuating sections which extend past a radially outer edge of the housing. An energy storage element is mounted on the outer side of the housing such that the energy storage device exerts a force on the actuating sections for urging the pressure plate away from the inner axial side. An assembly pretensioning arrangement is operative for holding the energy storage element in a pretensioned assembly position in which the energy storage device does not exert a force on the housing.

At least one driver disk is arranged axially adjacent to the first and second friction plates and has friction linings on both sides, which interact with the friction plates, and a spring which can apply a compressive force for actuation of the clutch to the at least one first friction plate. At least one of the friction plates is made at least in part from a metal matrix and at least one nonmetallic foreign phase included in the matrix, which together form a metal matrix composite material. In a further aspect of the invention, the clutch housing is likewise formed from a metal matrix composite material.
