Kupplungssystem

The invention relates to a clutch system (1) comprising a clutch device (2) and an actuation device (3) for engaging and/or disengaging the clutch device, said clutch device having at least one counter-pressure plate (4), at least one clutch cover (7) with at least one diaphragm spring (8) pivotally mounted on a pivoting radius (17), and at least one pressure plate (5) for frictionally clamping a clutch disk (6) between the pressure plate (5) and the counter-pressure plate (4), said pressure plate being movably mounted, limited in an axial direction (A) of the clutch device by the diaphragm spring. The diaphragm spring acts upon the contact plate in an active radius which is outside the pivoting radius in the radial direction of the clutch device and can be actuated by the actuation device in an actuation radius which is inside the pivoting radius in the radial direction, with iDP = (pivoting radius - actuation radius) / (active radius - pivoting radius)>= 5. The actuation device (3) has a clutch pedal (27) with a transmission ratio 3.5
