Abstract

Clutch arrangement provided with a housing and a clutch device, one of which serves as a clutch element carrier for a clutch element and the other serves as a friction region carrier. The clutch element has a carrier for a friction lining and a holding apparatus for receiving the carrier on the clutch element carrier, radially adjacently with respect to the friction lining. In a first radial region, the clutch housing has an axial projection at a first axial spacing from the clutch device and, with a radial offset with respect thereto, has an axial recess at a second axial spacing from the clutch device in a second radial region, and has a transition region radially between the axial projection and the axial recess, either the axial projection or the axial recess being intended to provide a bearing face for at least one component of the clutch device.

First claim

What is claimed is:

1. A clutch arrangement comprising:
a clutch housing;
a clutch device;
at least one clutch element;
a clutch element carrier, wherein one of the clutch housing or the clutch device serves at least indirectly as the clutch element carrier for the at least one clutch element,
at least one friction region carrier for at least one friction region, wherein the at least one clutch element can be brought at least substantially into an operative connection with the at least one friction region to establish a non-positive connection, or the at least one clutch element can be at least substantially disconnected from the at least one friction region in order to cancel the non-positive connection,
the at least one clutch element having a carrier for at least one friction lining, and, radially adjacently with respect to the at least one friction lining, the at least one clutch element having a holding apparatus for receiving the carrier of the at least one clutch element on the clutch element carrier;
wherein, in a first radial region, the clutch housing comprises:
an axial projection at a first axial spacing from the clutch device and, with a radial offset with respect thereto,
an axial recess at a second axial spacing from the clutch device in a second radial region, and
a transition region radially between the axial projection and the axial recess,

either the axial projection or the axial recess configures to provide a bearing face for at least one component of the clutch device based on a configuration of the clutch device,
wherein at least one clutch element carrier is configured to receive a plurality of clutch elements,
wherein the clutch element carrier uses the bearing face of the axial projection,
whereas the axial recess provides a clearance for the arrangement of a peripheral spring assembly of a torsional vibration damper, in a manner which is axially adjacent with respect to the bearing face of the axial recess.

2. The clutch arrangement according to claim 1 ,
wherein the clutch element carrier is configured to receive a single clutch element,
wherein the single clutch element is provided to use the bearing face of the axial recess,
whereas the clutch element carrier uses the axial projection of the clutch housing as an axial penetration space, during the establishing of the non-positive connection between the at least one clutch element and the at least one friction region.

3. The clutch arrangement according to claim 2 , wherein the at least one clutch element is fastened to the clutch element carrier and has at least one friction lining.

4. The clutch arrangement according to claim 1 ,
wherein the transition region is configured to change the axial projection into the axial recess by a double directional change, a first directional change bringing about a course change of the clutch housing from substantially radial to substantially axial, and a second directional change bringing about a course change from substantially axial to substantially radial.

5. The clutch arrangement according to claim 4 , wherein the clutch element carrier which uses the bearing face of the axial projection is guided radially as far as directly up to the first directional change from substantially radial to substantially axial.

6. The clutch arrangement according to claim 1 , wherein the first axial spacing of the clutch housing from the clutch device is greater than the second axial spacing of the clutch housing from the clutch device.

7. The clutch arrangement according to claim 1 , wherein the clutch device has a first clutch element carrier for at least one first clutch element and a second clutch element carrier for at least one second clutch element, of which first and second clutch element carriers, one of the first and second clutch element carriers is fastened to the bearing face on the axial projection of the clutch housing.
