Abstract

A dual clutch transmission arrangement (4) includes a first clutch (K1) and a second clutch (K2) for connecting a drive unit (2) to a first sub-transmission and to a second sub-transmission. The first clutch (K1) is connected to both transmission input shafts. A motor vehicle with the dual clutch transmission arrangement (4) is also provided.

Claims

1-15. -15. (canceled)

16. A dual clutch transmission arrangement (4), comprising:

a first clutch (K1) configured to selectively connect a drive unit (2) to a first sub-transmission; and

a second clutch (K2) configured to selectively connect the drive unit (2) to a second sub-transmission,

wherein the first clutch (K1) is connected to a transmission input shaft of the first sub-transmission and to a transmission input shaft of the second sub-transmission.

17. The dual clutch transmission arrangement of claim 16, wherein the second clutch (K2) is arranged within a part (8) of a transmission housing (6) that accommodates a gear set (42).

18. The dual clutch transmission arrangement of claim 17, wherein the second clutch (K2) is arranged between two gear set planes (38, 40).

19. The dual clutch transmission arrangement of claim 18, wherein the second clutch (K2) is arranged between two gear sets of odd gears.

20. The dual clutch transmission arrangement of claim 18, wherein the second clutch (K2) is arranged between two gear sets of even gears.

21. The dual clutch transmission arrangement of claim 18, wherein the second clutch (K2) is arranged between two gear sets of even gears and odd gears.

22. The dual clutch transmission arrangement of claim 17, wherein the second clutch (K2) is arranged proximate a transmission-end side of the transmission housing (6) and downstream from two gear set planes (38, 40).

23. The dual clutch transmission arrangement of claim 16, wherein the second clutch (K2) encloses a shaft (22, 24, 30, 44).

24. The dual clutch transmission arrangement of claim 16, wherein the first clutch (K1) is a launch clutch.

25. The dual clutch transmission arrangement of claim 16, wherein the transmission input shafts (22, 24) are coaxially arranged, and the first clutch (K1) is connected on an input side to an inner one of transmission input shafts.

26. The dual clutch transmission arrangement of claim 16, wherein the transmission input shafts (22, 24) are coaxially arranged, and the first clutch (K1) is connected on an output side to an outer one of the transmission input shafts.

27. The dual clutch transmission arrangement of claim 16, wherein the second clutch (K2) is connected on an input side to the transmission input shaft (24) of the second sub-transmission.

28. The dual clutch transmission arrangement of claim 16, further comprising a second drive unit (3).

29. The dual clutch transmission arrangement of claim 16, further comprising a separating clutch (K0) for disconnecting the first drive unit (2) from a drive train.

30. A motor vehicle comprising the dual clutch transmission arrangement of claim 16.
