Abstract

A coupling arrangement for the powertrain of a vehicle with a clutch housing with a feed arrangement for feed medium contained in the clutch housing and with a clutch mechanism, wherein the clutch mechanism has input-side clutch units communicating with an input-side clutch unit carrier, output-side clutch units communicating with an output-side clutch unit carrier, and a pressing device through which an operative connection between the input-side clutch units and the output-side clutch units can be produced or cancelled, and wherein the input-side clutch unit carrier is part of the feed arrangement. The feed arrangement further has a feed device which is associated with the input-side clutch unit carrier and which is connected to the input-side clutch unit carrier and/or to the pressing device so as to be fixed with respect to relative rotation.

First claim

What is claimed:

1. A coupling arrangement ( 1 ) for the powertrain of a vehicle ( 1 ) comprising:
a clutch housing ( 3 );
a feed arrangement ( 75 ) for feed medium contained in the clutch housing ( 3 );
an input-side clutch unit carrier ( 10 ) connected so as to be fixed with respect to rotation relative to the clutch housing ( 3 );
a clutch mechanism ( 90 ), wherein the clutch mechanism ( 90 ) comprising input-side clutch units ( 20 ) communicating with the input-side clutch unit carrier ( 10 ), an output-side clutch unit carrier ( 44 ) connected so as to be fixed with respect to rotation relative to a driven end ( 54 ), output-side clutch units ( 40 ) communicating with the output-side clutch unit carrier ( 44 ) and a pressing device ( 30 ) through which an operative connection between the input-side clutch units ( 20 ) and the output-side clutch units ( 40 ) can be produced or cancelled;
wherein the input-side clutch unit carrier ( 10 ) is part of the feed arrangement ( 75 ), and the feed arrangement ( 75 ) further comprising a feed device ( 38 ) associated with the input-side clutch unit carrier ( 10 ) and which is connected to the input-side clutch unit carrier ( 10 ) and/or to the pressing device ( 30 ) so as to be fixed with respect to relative rotation; and
additionally comprising at least one disconnecting device ( 17 ) for disconnecting the input-side from the output-side clutch units, and wherein the feed device ( 38 ) is constructed as a centering device for the at least one disconnecting device ( 17 ).

2. The coupling arrangement ( 1 ) according to claim 1 , wherein the feed device ( 38 ) comprises a driving arrangement ( 70 ) for connecting the feed device ( 38 ) to the input-side clutch unit carrier ( 10 ) and/or to the pressing device ( 30 ) so as to be fixed with respect to relative rotation.

3. The coupling arrangement ( 1 ) according to claim 2 , wherein the input-side clutch unit carrier ( 10 ) and/or the pressing device ( 30 ) comprise a cutout ( 66 , 68 ), and the driving arrangement ( 70 ) has at least one flow passage ( 34 ) extending into the corresponding cutout ( 66 , 68 ) of the input-side clutch unit carrier ( 10 ) and/or pressing device ( 30 ) for rotationally locking the feed device ( 38 ) to the input-side clutch unit carrier ( 10 ) and/or the pressing device ( 30 ).

4. The coupling arrangement ( 1 ) according to claim 3 , wherein the at least one flow passage ( 34 ) extends into the corresponding cutout ( 66 , 68 ) while preserving a positive engagement with the input-side clutch unit carrier ( 10 ) and/or pressing device ( 30 ).

5. The coupling arrangement ( 1 ) according to claim 2 , wherein the feed device ( 38 ) includes a support ( 36 ) which comprises the driving arrangement ( 70 ) and a blading ( 35 ) for influencing the movement of the feed medium.

6. The coupling arrangement ( 1 ) according to claim 5 , wherein the support ( 36 ) comprises the driving arrangement ( 70 ) at a side facing the input-side clutch unit carrier ( 10 ) and the blading ( 35 ) at a side remote of the driving arrangement ( 70 ).

7. The coupling arrangement ( 1 ) according to claim 1 , wherein the disconnecting device ( 17 ) for the clutch units acts on clutch units which are adjacent to one another so that the adjacent clutch units are acted upon by axial forces in directions facing away from one another.

8. The coupling arrangement ( 1 ) according to claim 1 , wherein at least one of the feed device ( 38 ) and the disconnecting device ( 17 ) is at least substantially annular and surrounds a central axis ( 2 ) of the clutch housing ( 3 ).

9. The coupling arrangement ( 1 ) according to claim 1 , wherein the input-side clutch unit carrier ( 10 ) at least partially encloses the feed device ( 38 ).

10. The coupling arrangement ( 1 ) according to claim 1 , wherein either the input-side clutch unit carrier ( 10 ) or the pressing device ( 30 ) is constructed for receiving a seal ( 80 ) which is operative relative to the other of the input-side clutch unit carrier ( 10 ) or pressing device ( 30 ).

11. The coupling arrangement ( 1 ) according to claim 1 , wherein the output-side clutch unit carrier ( 44 ) comprises a feed brake ( 100 ) for slowing down the flow of feed medium.

12. The coupling arrangement ( 1 ) according to claim 1 , wherein the feed device ( 38 ) is produced as a plastic injection-molded part, as a metal die casting or as a sintered part.

13. The coupling arrangement ( 1 ) according to claim 1 , wherein the feed device ( 38 ) is arranged radially inside the respective clutch units ( 20 , 40 ) of the clutch mechanism ( 90 ).

14. The coupling arrangement ( 1 ) according to claim 1 , wherein the input-side clutch unit carrier ( 10 ) at least partially encloses the disconnecting device ( 7 ).
