Title: FRICTION CLUTCH
Abstract:
The invention relates to a friction clutch (1) for coupling a drive shaft of a motor-vehicle engine to a transmission input shaft of a motor-vehicle transmission. The friction clutch (1) comprises at least one clutch cover (2), a pressure plate (5), which can be moved along an axis of rotation (3) of the friction clutch (1) in an axial direction, and a lever element (6) for actuating the pressure plate (5). The pressure plate (5) has a plurality of holders (7) for holding at least one disk (8), each of the holders (7) forming an interlocking connection with each of the at least one disk (8) in a peripheral direction. The at least one disk (8) has, within the holders (7) in a radial direction, a friction surface (12) on each of the end faces (11) which face in the axial direction, each friction surface (12) being frictionally connectable to one of a plurality of friction disks (13, 14, 15) of the friction clutch (1) in order to transmit a torque. At least one first friction disk (14) can be arranged between a counter pressure plate (16) and the at least one disk (8) and one second friction disk (13, 14) can be arranged between the at least one disk (8) and the pressure plate (5).Both friction disks (13, 14) can be connected to a hub (17) interlockingly in the peripheral direction.
