Abstract

A force transmission device having a hydrodynamic component, disposed between an input and an output, comprising at least a pump shell and a turbine shell, forming an operating cavity in combination, with an actuatable clutch device for at least partially bridging the hydrodynamic component, comprising a clutch component for at least partially bridging the hydrodynamic component, comprising a first clutch component connected with the input and a second clutch component at least indirectly connected to the output, which can be brought into operative engagement with one another through an actuation device, with a vibration absorber disposed in the force flow at least subsequent to the actuatable clutch device, with a housing coupled with the input or with an element coupled non-rotatably to the input and coupled with the pump shell.

Claims (16)

1. A force transmission device ( 1 ) comprising:

an input (E) and an output (A);

a hydrodynamic component ( 3 ) disposed between the input (E) and the output (A), comprising at least a pump shell (P) and a turbine shell (T), forming an operating cavity ( 13 ) in combination, and comprising an actuatable clutch device ( 4 ) for at least partially bridging the hydrodynamic component ( 3 ), comprising a first clutch component ( 7 ) connected to the input (E) and a second clutch component ( 8 ) at least indirectly connected to the output (A), which can be brought into operative engagement with one another through an actuation device ( 9 );

a vibration damper ( 22 ), disposed at least subsequent to the actuatable clutch device in a force flow;

a housing ( 17 ), coupled with the input (E) or with an element connected non-rotatably with said input, and coupled with the pump shell (P), which encloses the actuatable clutch device ( 4 ) and the vibration damper ( 22 ) and forms an intermediary cavity ( 15 ); and,

means ( 40 ) for separating a channel and/or a first chamber ( 19 ) from the intermediary cavity ( 15 ) for generating an oriented flow through the actuatable clutch device ( 4 ), wherein:

the chamber ( 19 ) is formed by the actuation device ( 9 ) and by a wall ( 41 ) disposed pressure tight between the second clutch component ( 8 ) and the output (A), or by an element connected non-rotatably with said output;

the wall ( 41 ) is formed by a seal plate ( 36 ), which can be connected non-rotatably with the second clutch component ( 8 ) or with the damper input ( 23 ); and,

coupling of the seal element ( 36 ) with the second clutch component ( 8 ) is performed on a common diameter with a connection of the second clutch component ( 8 ) with the damper input ( 23 ), while using the same connection elements.

2. The force transmission device ( 1 ) according to claim 1 , wherein the actuation device ( 9 ) comprises at least a piston element ( 10 ), which can be actuated by a second chamber, which can be loaded with pressure means, wherein the first chamber ( 19 ) and/or the channel is formed by the piston element ( 10 ) and by the wall ( 41 ).

3. The force transmission device ( 1 ) according to claim 1 , wherein the wall ( 41 ) is at least partially formed by the second clutch component ( 8 ) of the actuatable clutch device ( 4 ).

4. The force transmission device ( 1 ) according to claim 3 , wherein the support ( 30 ) of the second clutch component ( 8 ) is configured as an inner disk carrier.

5. The force transmission device ( 1 ) according to claim 1 , wherein the actuatable clutch device ( 4 ) is configured in disk construction, wherein each clutch component ( 7 , 8 ) comprises a support ( 27 , 30 ) and thereon friction surface bearing or friction surface forming elements ( 28 , 29 ), movably guided thereon in axial direction and connected non-rotatably therewith, and the wall ( 41 ) is completely formed by the support ( 30 ) of the second clutch component ( 8 ).

6. The force transmission device ( 1 ) according to claim 1 , wherein the vibration damper ( 22 ) comprises at least one damper input ( 23 ) and one damper output ( 24 ), coupled to one another through means ( 26 ) for torque transmission and damper coupling, wherein the wall ( 41 ) is formed by the damper input ( 23 ), comprising at least one drive disk ( 23 . 1 ) coupled non-rotatably with the second clutch component ( 8 ), and a seal device ( 42 ), disposed between the drive disk ( 23 . 1 ) and the output (A), or the element connected non-rotatably with said output.

7. The force transmission device ( 1 ) according to claim 1 , wherein the first clutch component ( 7 ) comprises radially oriented pass-through openings ( 37 ) in the support ( 27 ).

8. The force transmission device ( 1 ) according to claim 1 , wherein the input (E) is formed by the housing ( 17 ) or by an element coupled non-rotatably with said input, and the output (A) is formed by a transmission input shaft ( 2 ) or by an element coupled non-rotatably with said output.
