Abstract

A torsional damper arrangement for a motor vehicle with a housing. The housing encloses a wet space. A momentum start clutch arrangement is arranged in the housing.

First claim

The invention claimed is:

1. A torsional damper arrangement for a motor vehicle comprising:
a housing, wherein the housing is configured to enclose a wet space; and
a momentum start clutch arrangement arranged in the housing,
wherein a part of the housing of the torsional damper arrangement inclined at a bevel and is configured as a friction surface of a friction clutch of the momentum start clutch arrangement,
wherein the momentum start clutch arrangement comprises an actuation device with at least two actuation pistons,
wherein the actuation device of the momentum start clutch arrangement forms a part of a flywheel mass of the torsional damper arrangement.

2. The torsional damper arrangement according to claim 1 , wherein the momentum start clutch arrangement comprises a friction clutch and a dog clutch.

3. The torsional damper arrangement according to claim 1 , wherein a dog element of a dog clutch is formed at one of the at least two actuation pistons.

4. The torsional damper arrangement according to claim 1 , wherein a friction surface of a friction clutch is formed at one of the at least two actuation pistons.

5. The torsional damper arrangement according to claim 1 , wherein the actuation device has an individual feed line.

6. The torsional damper arrangement according to claim 1 , wherein the at least two actuation pistons are supported at an intermediate wall in the torsional damper arrangement.

7. The torsional damper arrangement according to claim 6 , wherein the at least two actuation pistons are arranged on a same side of the intermediate wall of the torsional damper arrangement.

8. The torsional damper arrangement according to claim 6 , wherein the intermediate wall is connected to a primary side of the torsional damper arrangement.

9. The torsional damper arrangement according to claim 8 , wherein the primary side of the torsional damper arrangement is supported on an input hub of the momentum start clutch arrangement.

10. The torsional damper arrangement according to claim 1 , wherein respective pressurized surfaces of the at least two actuation pistons have a predetermined ratio selected depending on at least one preloading element.

11. The torsional damper arrangement according to claim 1 , wherein the actuation device has an individual pressure space.

12. The torsional damper arrangement according to claim 1 , wherein the torsional damper arrangement has two input hubs.

13. The torsional damper arrangement according to claim 1 , wherein the torsional damper arrangement has exactly one input hub.

14. The torsional damper arrangement according to claim 1 , wherein an entire torque is transmittable via the momentum start clutch arrangement.

15. The torsional damper arrangement according to claim 1 , wherein a friction element of a friction clutch of the momentum start clutch arrangement is connected to an input hub of the torsional damper arrangement so as to be fixed with respect to rotation relative to the an input hub.

16. The torsional damper arrangement according to claim 15 , wherein the friction element is formed as a friction lamina.

17. A torsional damper arrangement for a motor vehicle comprising:
a housing, wherein the housing is configured to enclose a wet space; and
a momentum start clutch arrangement arranged in the housing,
wherein the momentum start clutch arrangement comprises an actuation device with at least two actuation pistons,
wherein the at least two actuation pistons are supported at an intermediate wall in the torsional damper arrangement, and
wherein the at least two actuation pistons are arranged on opposite sides of the intermediate wall.

18. A motor vehicle comprising:
a torsional damper arrangement, comprising:
a housing, that encloses a wet space; and
a momentum start clutch arrangement arranged in the housing
wherein the momentum start clutch arrangement comprises an actuation device with at least two actuation pistons,
wherein the at least two actuation pistons are supported at an intermediate wall in the torsional damper arrangement, and

wherein the at least two actuation pistons are arranged on opposite sides of the intermediate wall.
