Abstract

The disclosure relates to a drive train for a motor vehicle containing an internal combustion engine, a transmission connected downstream thereof, drive wheels and a differential arranged between the drive wheels and the transmission. In order to eliminate or at least reduce the vibrational eigenmodes behind the transmission, a centrifugal pendulum is assigned adjacent to the differential.

First claim

The invention claimed is:

1. A drive train for a motor vehicle comprising: an internal combustion engine, a transmission connected downstream thereof, drive wheels, a differential arranged between the drive wheels and the transmission, and a drive shaft provided between the transmission and the differential, wherein a centrifugal pendulum is arranged between the drive shaft and the differential and is disposed adjacent to the differential.

2. The drive train according to claim 1 , wherein the transmission is installed at a front of the motor vehicle and the drive wheels are provided for rear-wheel drive.

3. The drive train according to claim 1 , wherein the centrifugal pendulum is enclosed separately from a housing of the differential by a centrifugal pendulum housing.

4. The drive train according to claim 1 , wherein an articulated connection is provided between an input shaft of the differential and the drive shaft.

5. The drive train according to claim 4 , wherein the centrifugal pendulum is assigned to the input shaft.

6. The drive train according to claim 4 , wherein the centrifugal pendulum is assigned to the drive shaft.

7. The drive train according to claim 4 , wherein a centrifugal pendulum housing is rotatably received on the drive shaft or on the input shaft.

8. The drive train according to claim 7 , wherein the centrifugal pendulum housing receives a pendulum mass carrier which is non-rotatably connected to the drive shaft or the input shaft and on which pendulum masses which can be pivoted along a predetermined pendulum path are arranged distributed over a circumference on both sides in a centrifugal force field.

9. The drive train according to claim 4 , wherein the centrifugal pendulum housing is outwardly supported in a non-rotatable manner.

10. A drive train for a motor vehicle comprising:
an internal combustion engine,
a transmission connected downstream of the internal combustion engine;
drive wheels;
a differential arranged between the drive wheels and the transmission; and
a centrifugal pendulum arranged between the transmission and the differential, the centrifugal pendulum being arranged external to a housing of the transmission.

11. The drive train of claim 10 , wherein the centrifugal pendulum is disposed adjacent to the differential.

12. The drive train of claim 10 , wherein the drive wheels are provided for rear-wheel drive.

13. The drive train of claim 10 , wherein the centrifugal pendulum is arranged external to a housing of the differential.

14. The drive train of claim 10 , wherein the centrifugal pendulum is enclosed separately from the housing of the transmission.

15. The drive train of claim 10 , further comprising a drive shaft provided between the transmission and the differential, wherein the centrifugal pendulum is connected to an input shaft of the differential or the drive shaft.

16. The drive train of claim 15 , wherein an articulated connection is provided between the input shaft of the differential and the drive shaft.

17. A drive train for a motor vehicle comprising:
an internal combustion engine,
a transmission connected downstream of the internal combustion engine and arranged at a front of the motor vehicle;
drive wheels arranged for rear-wheel drive;
a differential arranged between the drive wheels and the transmission; and
a centrifugal pendulum disposed adjacent to the differential.

18. The drive train of claim 17 , wherein the centrifugal pendulum is arranged external to a housing of the transmission and external to a housing of the differential.

19. The drive train of claim 18 , wherein the centrifugal pendulum is disposed between the transmission and the differential.

20. The drive train of claim 17 , further comprising a drive shaft provided between the transmission and the differential, wherein the centrifugal pendulum is connected to an input shaft of the differential or the drive shaft.
