Abstract: A clutch device for a drivetrain of a vehicle, has a first clutch component for introducing torque and a second clutch component for transmission of torque. The second clutch component is rotationally uncouplable from the first clutch component. First frictional elements of the first clutch component and second frictional elements of the second clutch component may be connectible so that they transmit torque. The partial self-amplification of the clutch device is executable here by the leaf spring unit, while the second spring unit exerts a static clamping force. The leaf spring unit and the second spring unit are rotationally uncoupled.

Abstract: A hybrid drive train of a motor vehicle is discloses that has a first connecting component, which can be connected to an output shaft of an internal combustion engine, and a second connecting component, which can be connected to a shaft of a transmission and/or a rotor of an electric drive machine. The connection transmits torque when the clutch is in a closed position and is arranged to interrupt torque flow in an open position. A clutch actuation system switches the clutch between the two positions and has a ramp mechanism operatively connected to the components by a planetary gearing. The first component has two conducting segments connected in a rotationally fixed manner by a torque storage device, designed so the segments are elastically preloaded in a direction of rotation in relation to each other at least in the closed position.

Abstract: A clutch system for a vehicle drivetrain includes a first clutch component, a second clutch component, a leaf spring unit, and a second spring element. The first clutch component has first friction elements. The second clutch component has second friction elements connectable to the first friction elements in a torque-transmitting manner. The leaf spring unit is for providing a partial self-intensification and the second spring element is for exerting a static force. The clutch system also has a first hub and a second hub. A one of the second friction elements is rotationally connected to the first hub by the leaf spring unit and an another one of the second friction elements is rotationally coupled directly to the second hub.

Abstract: A clutch (1), includes an input side (2) which is prepared for the introduction of torque, and an output side (3) which is prepared for the forwarding of torque to at least one transmission input shaft (4). The clutch includes first friction elements (5) as part of a first multiple disc assembly (6) and having second friction elements (7) as part of a second multiple disc assembly (8). The first friction elements (5) are connected to the input side (2) in a torque-transmitting manner and the second friction elements (7) are connected to the output side (3) in a torque-transmitting manner. The first and second friction elements (5, 7) can be brought into frictional engagement with one another by way of a pressing force (F), in order to transmit a torque (M) from the input side (2) to the output side (3). At least one leaf spring (9) is provided which is configured to boost the pressing force (F).
