The invention relates to a dual clutch for coupling a drive shaft of a motor vehicle engine to a transmission shaft of a motor vehicle transmission and/or a power takeoff of the motor vehicle, in particular an output shaft, comprising a first friction clutch (12) for frictional compression of a first clutch disc (16), which can be coupled to the transmission shaft, between a first pressure plate (18) and a first counter-plate (20), wherein the first pressure plate can be displaced in an axial direction for closing the first friction clutch, also comprising a second friction clutch (14) for compression of a second clutch disc (24) which can be coupled to the power takeoff, between a second pressure plate (26) and a second counter-plate (28), wherein the second pressure plate can be displaced in the axial direction for closing the second friction clutch, and also comprising a first actuating element (22) for displacing the first pressure plate and a second actuating element (30) for displacing the second pressure plate, wherein the second pressure plate is connected to a thrust collar operatively connected to the second actuating element for transmission of the displacement movement. According to the invention the second actuating element has at least one spring element (34) for preloading, wherein the at least one spring element is disposed between the second actuating element and the thrust collar. In this way a reduction of the pressing force can be avoided in the event of wear and the dependence upon tolerances of the pressing force and engaging force can be reduced. |
