Abstract

A clutch arrangement arranged between a drive unit and a transmission, with at least one multi-plate clutch having an outer plate carrier and an actuation element. The actuation element, particularly a piston, has openings for receiving the outer plate carrier.

First claim

The invention claimed is:

1. A clutch arrangement configured to be arranged between a drive unit and a transmission, comprising:
an actuation element; and
at least three multi-plate clutches, wherein each of the at least three multi-plate clutches comprise a respective outer plate carrier, and the respective outer plate carriers form a housing of the clutch arrangement,
wherein the actuation element defines openings for receiving radially inwardly extending fingers arranged on a radially innermost portion of a radially outermost one of the outer plate carriers of the multi-plate clutches, and wherein the radially outermost outer plate carrier is rotationally fixed to a radially inner outer plate carrier by the fingers.

2. The clutch arrangement according to claim 1 , wherein the openings are formed as elongate holes.

3. The clutch arrangement according to claim 1 , wherein the outer plate carrier is arranged on an input side of the at least one multi-plate clutch.

4. The clutch arrangement according to one of claim 1 , wherein the radially outermost plate carrier is welded to the radially inner outer plate carrier.

5. The clutch arrangement according to claim 1 , wherein one of the multi-plate clutches is a starter clutch.

6. The clutch arrangement according to claim 1 , wherein one of the multi-plate clutches is a disconnect clutch.

7. The clutch arrangement according to claim 1 , wherein the clutch arrangement is a triple clutch arrangement.

8. The clutch arrangement according to claim 1 , wherein the actuation element is a piston.

9. A hybrid dual clutch transmission arrangement, comprising:
a clutch arrangement configured to be arranged between a drive unit and a transmission, and comprising:
an actuation element; and
at least three multi-plate clutches, wherein each of the at least three multi-plate clutches comprise a respective outer plate carrier, and the respective outer plate carriers form a housing of the clutch arrangement,
wherein the actuation element defines openings for receiving radially inwardly extending fingers arranged on a radially innermost portion of a radially outermost one of the outer plate carriers of the multi-plate clutches, and wherein the radially outermost outer plate carrier is rotationally fixed to a radially inner outer plate carrier by the fingers.

10. A motor vehicle comprising:
a drive unit;
a transmission; and
at least one of a clutch arrangement configured to be arranged between the drive unit and the transmission and a dual clutch transmission arrangement configured to be arranged between the drive unit and the transmission, each comprising:
an actuation element; and
at least three multi-plate clutches, wherein the at least three multi-plate clutches comprise a respective outer plate carrier, and the respective outer plate carriers form a housing of the clutch arrangement,
wherein the actuation element defines openings for receiving radially inwardly extending fingers arranged on a radially innermost portion of a radially outermost one of the outer plate carriers of the multi-plate clutches, and wherein the radially outermost outer plate carrier is rotationally fixed to a radially inner outer plate carrier by the fingers.

11. The clutch arrangement according to claim 1 , wherein there are no further housing parts of which the housing is comprised other than the outer plate carriers.
