Abstract

An assembly for a hybrid drivetrain of a motor vehicle, having a first torque transmission device and a second torque transmission device connected thereto so as to transmit torque. The first torque transmission device is arranged to be axially spaced apart from the second torque transmission device and the second torque transmission device has a smaller radial extension than the first torque transmission device. An installation space for a drivetrain device is defined radially above the second torque transmission device such that said drivetrain device is delimited axially by the first torque transmission device. A spacer device is arranged between the two torque transmission devices in the torque transmission path for axial spacing and is designed such that an axially definable minimum spacing between the defined installation space and the first torque transmission device is maintained and has a balancing device for compensating for imbalance of the assembly.

First claim

The invention claimed is:

1. An assembly for a hybrid drivetrain of a motor vehicle, comprising:
a first torque transmission device;
a second torque transmission device connected to the first torque transmission device to transmit torque,
wherein the first torque transmission device is arranged to be axially spaced apart from the second torque transmission device,
wherein the second torque transmission device has a smaller radial extent than the first torque transmission device, and
wherein an installation space for a drivetrain device is defined radially above the second torque transmission device, such that the installation space is axially delimited by the first torque transmission device; and

a spacing device is arranged for axial spacing in a torque transmission path between the a first torque transmission device and the second torque transmission device, the spacing device is designed such that an axially definable minimum spacing between the installation space and the first torque transmission device is maintained, and in that the spacing device has a balancing device for compensating an unbalance of at least the assembly.

2. The assembly as claimed in claim 1 , wherein the spacing device is arranged radially below the installation space.

3. The assembly as claimed in claim 1 , wherein the spacing device extends in a radial direction between the first torque transmission device and the second torque transmission device.

4. The assembly as claimed in claim 1 , wherein the spacing device has an axial offset in a radial direction.

5. The assembly as claimed in claim 1 , wherein the spacing device has at least one aperture and/or at least one depression in a circumferential direction.

6. The assembly as claimed in claim 5 , wherein the spacing device is formed in a region of the at least one aperture for receiving an additional mass.

7. The assembly as claimed in claim 6 , wherein the at least one aperture is configured for a clamping connection and/or a clip connection.

8. The assembly as claimed in claim 1 , wherein the spacing device has at least one separately arranged additional mass.

9. The assembly as claimed in claim 8 , wherein the at least one separately arranged additional mass is U-shaped in cross section.

10. The assembly as claimed in claim 9 , wherein the at least one separately arranged additional mass has a horizontal limb.

11. The assembly as claimed in claim 1 , wherein the spacing device has an axial thickness that is constant over its radial extent.

12. The assembly as claimed in claim 1 , wherein at least one of the the first torque transmission device and the second torque transmission device is an absorber.

13. A drivetrain of a motor vehicle having an assembly comprising:
a first torque transmission device;
a second torque transmission device connected to the first torque transmission device to transmit torque,
wherein the first torque transmission device is arranged to be axially spaced apart from the second torque transmission device,
wherein the second torque transmission device has a smaller radial extent than the first torque transmission device, and
wherein an installation space for a drivetrain device is defined radially above the second torque transmission device, such that the installation space is axially delimited by the first torque transmission device; and
a spacing device is arranged for axial spacing in a torque transmission path between the a first torque transmission device and the second torque transmission device, the spacing device is designed such that an axially definable minimum spacing between the installation space and the first torque transmission device is maintained, and in that the spacing device has a balancing device for compensating an unbalance of at least the assembly.

14. The drivetrain of claim 13 , wherein the drivetrain is a hybrid drivetrain.
