Abstract

A clutch comprises an input side and an output side, which are disposed rotatably. First frictional partners are non-rotatably connected with the input side and axially movable and second frictional partners are non-rotatably connected with the output side and axially movable. Furthermore, a compression device is provided to compress the frictional partners axially, in order to provide a torsional connection between the input side and the output side. Both sides are decoupled axially from the respective frictional partners with which they are engaged.

First claim

What is claimed is:

1. A clutch, comprising:
an input side, comprising:
an input component;
an outer basket; and,
a first decoupling device having a first end fixedly secured to the input component and a second end fixedly secured to the outer basket;

an output side disposed rotatably to the input side, comprising:
an output component;
an inner basket; and,
a second decoupling device having a first end fixedly secured to the output component and a second end fixedly secured to the inner basket;

first frictional partners axially movable and non-rotatably connected to the outer basket;
second frictional partners axially movable and non-rotatably connected to the inner basket; and,
a compression device arranged to compress the first and second frictional partners axially, providing a non-rotatable connection between the input side and the output side;
wherein, the first decoupling device is operatively arranged such that the outer basket is axially movable relative to the input component and the second decoupling device is operatively arranged such that the inner basket is axially movable relative to the output component.

2. The clutch as recited in claim 1 , wherein the compressed first and second frictional partners are jointly movable axially relative to the input component and the output component.

3. The clutch as recited in claim 1 , wherein the first decoupling device and the second decoupling device are axially elastic elements operatively arranged to transmit torque between the input side and the output side.

4. The clutch as recited in claim 3 , wherein the axially elastic elements comprise a diaphragm spring.

5. The clutch as recited in claim 3 , wherein the axially elastic elements have an elasticity such that, when the compression device axially compresses the first and second frictional partners, the outer basket and the inner basket are free of axial forces exerted by the compression device.

6. The clutch as recited in claim 1 , further comprising a bearing operatively arranged such that the outer basket is axially moveable relative to the input component or the inner basket is axially movable relative to the output component.

7. The clutch as recited in claim 1 , wherein the compression device comprises a hydraulic actuator operatively arranged to axially compress the first and second frictional partners.

8. The clutch as recited in claim 1 , wherein the compression device comprises two hydraulic actuators operatively arranged antiparallel to axially compress the first and second frictional partners.
