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.

A clutch device for a drivetrain of a vehicle comprising:
- a first clutch component for introduction of torque;
- a second clutch component for transmission of torque, the second clutch component being rotationally uncouplable from the first clutch component, first frictional elements of the first clutch component and second frictional elements of the second clutch component being connectible so that the first frictional elements and the second frictional elements transmit torque;
- a leaf spring unit;
- and
- a second spring unit, the leaf spring unit being configured for achieving a partial self-amplification of the clutch device, while a second spring unit exerts a static clamping force, the leaf spring unit and the second spring unit being rotationally uncoupled.
A method of constructing a clutch device for a drivetrain of a vehicle comprising:
- arranging a first clutch component for introduction of torque with respect to a second clutch component for transmission of torque such that first frictional elements of the first clutch component and second frictional elements of the second clutch component are rotationally couplable to each other and rotationally uncouplable from each other;
- and
- providing a leaf spring unit for achieving a partial self-amplification of the clutch device and providing a second spring unit for exerting a static clamping force such that the leaf spring unit and the second spring unit being are rotationally uncoupled.
A clutch device for a drivetrain of a vehicle comprising:
- a first clutch component for introduction of torque, the first clutch component including first frictional elements;
- a second clutch component for transmission of torque, the second clutch component including second frictional elements, the first frictional elements and the second frictional elements being rotationally couplable to each other being rotationally uncouplable from each other;
- a first spring unit connected non-rotatably to the second clutch component and configured for transferring the torque via a first subset of the second frictional elements from the second clutch component to a transmission output hub;
- and
- a second spring unit configured for exerting a static clamping force on the second clutch component, the first spring unit and the second spring unit being rotationally uncoupled.
