Abstract

A dual clutch arrangement for a dual clutch transmission includes a first clutch and a second clutch. The output of the first clutch is connected to the input of the second clutch. A dual clutch transmission arrangement with the dual clutch arrangement and a motor vehicle with the dual clutch arrangement are also provided.

First claim

The invention claimed is:

1. A dual clutch arrangement ( 48 ) for a dual clutch transmission, comprising:
a first clutch (K 0 ); and
a second clutch (K 1 ),
wherein an output ( 16 ) of the first clutch (K 0 ) is connected to an input ( 18 ) of the second clutch (K 1 ),
wherein the input ( 18 ) of the second clutch (K 1 ) is directly connectable to a second drive unit ( 3 ) such that the second drive unit ( 3 ) is operable to rotate the input ( 18 ) of the second clutch (K 1 ) both when the second clutch (K 1 ) is engaged and when the second clutch (K 1 ) is disengaged.

2. The dual clutch arrangement of claim 1 , wherein the dual clutch arrangement ( 48 ) is a preassembled module.

3. The dual clutch arrangement of claim 1 , wherein the first clutch (K 0 ) is a separating clutch for disconnecting an internal combustion engine ( 2 ) from the rest of a drive train.

4. The dual clutch arrangement of claim 1 , wherein the second clutch (K 1 ) is configurated to connect to a transmission input shaft ( 22 , 24 ).

5. The dual clutch arrangement of claim 1 , wherein the second clutch (K 1 ) is configurated to connect to two transmission input shafts ( 22 , 24 ).

6. The dual clutch arrangement of claim 1 , wherein the first clutch (K 0 ) and the second clutch (K 1 ) are radially nested.

7. The dual clutch arrangement of claim 1 , wherein an input of the first clutch (K 0 ) is connectable to a first drive unit ( 2 ).

8. The dual clutch arrangement of claim 1 , wherein the input ( 18 ) of the second clutch (K 1 ) is connected to the second drive unit ( 3 ) at a gearwheel 48 connected to the input ( 18 ) of the second clutch (K 1 ).

9. The dual clutch arrangement of claim 8 , wherein the gearwheel 48 is arranged between the first and second clutches K 0 , K 1 .

10. The dual clutch arrangement of claim 1 , wherein the first and second clutches (K 0 , K 1 ) are multi-disk clutches.

11. The dual clutch arrangement of claim 1 , wherein an output disk carrier of the first clutch (K 0 ) and an input disk carrier of the second clutch (K 1 ) comprise a common section.

12. A dual clutch transmission arrangement, comprising the dual clutch arrangement of claim 1 .

13. A motor vehicle comprising the dual clutch transmission arrangement of claim 12 .
