MULTI-PLATE CLUTCH FOR MOTOR VEHICLES, IN PARTICULAR MOTORCYCLES

摘要

The invention relates to a multi-plate clutch for motor vehicles, in particular motorcycles, comprising a primary wheel (11) which is coupled to the flywheel of an internal combustion engine and which is rotatably mounted on a transmission input shaft (10), a clutch basket (12) which is rigidly connected to the primary wheel, a driver (13) which is arranged concentrically with respect to the transmission input shaft and rigidly connected thereto, a pressure plate (14) which is axially displaceable with the driver but connected in a rotationally fixed fashion thereto, a pressure pot (16) which is rigidly connected to the pressure plate, a diaphragm spring (17) which is supported on an outer circumferential region on the driver and on an inner circumferential region on the pressure pot, a packet of annular clutch plates (18) which are alternately connected to the driver or to the basket at the inner circumference or outer circumference in a rotationally fixed but axially displaceable fashion - the plates being clamped in between the pressure plate and the driver - a disengagement bearing (19) which is arranged coaxially with respect to the transmission input shaft and by means of which an axial disengagement force can be transmitted to the pressure plate, and a pressure piece (20) which is inserted into the inner ring of the disengagement bearing and bears against the latter with an annular flange. The pressure piece (20) is provided with a projection (21) which is guided in a bore (22) in the transmission input shaft (10) so as to carry out a coaxial movement.
