Abstract

A drive assembly for a motor vehicle includes a drive, a transmission that can be driven by the drive, a drive housing, a transmission housing, and a fastening device. The drive is arranged in the drive housing, and the transmission is arranged in the transmission housing. The drive housing or the transmission housing can be fastened on a carrier by way of the fastening device. The fastening device includes a plurality of vibration dampers and sleeve elements. The sleeve elements surround the vibration dampers.

First claim

What is claimed is:

1. A drive assembly for a motor vehicle, said drive assembly comprising:
a drive,
a transmission that is configured to be driven by the drive,
a drive housing,
a transmission housing, and
a fastening means,
wherein the drive is arranged in the drive housing, and the transmission is arranged in the transmission housing,
wherein either the drive housing or the transmission housing is configured to be fastened on a carrier by way of the fastening means,
wherein the fastening means comprises a plurality of vibration damping means and sleeve elements,
wherein the sleeve elements surround the vibration damping means,
wherein the fastening means comprises fastening elements,
wherein the vibration damping means, in each case, comprise a through-opening through each of which one of the fastening elements is passed in an axial direction,
wherein the fastening elements are fastened on the transmission housing or on the drive housing, and
wherein each vibration damping element has a first portion having a first diameter, and a second portion, which protrudes from the first portion in the axial direction, that has a second diameter smaller than the first diameter and upon which a head of one of the fastening elements rests either directly or indirectly.

2. The drive assembly as claimed in claim 1 , wherein either the transmission housing or the drive housing is configured to be fastened on a single carrier by way of the fastening means.

3. The drive assembly as claimed in claim 1 , wherein the vibration damping means is of ring-shaped design.

4. The drive assembly as claimed in claim 1 , wherein the fastening elements are bolts or screws.

5. The drive assembly as claimed in claim 1 , wherein the fastening means comprises an intermediate component, wherein the intermediate component is fastened firmly on the drive housing or on the transmission housing.

6. The drive assembly as claimed in claim 1 , wherein the fastening means comprises three vibration damping means.

7. The drive assembly as claimed in claim 1 , wherein the drive assembly comprises a further fastening means, wherein the drive housing is fastened on the carrier by way of the fastening means, and wherein the further fastening means comprises a plurality of further vibration damping means, by way of which the transmission housing is fastened on a further carrier.

8. The drive assembly as claimed in claim 1 , wherein the transmission housing is configured to be fastened on the carrier by way of the vibration damping means of the fastening means, and wherein the drive assembly is free from further vibration damping means by way of which the transmission housing or the drive housing is fastened on the carrier or on a further carrier.

9. A motor vehicle comprising the drive assembly as claimed in claim 1 , wherein the motor vehicle comprises the carrier.

10. The drive assembly as claimed in claim 1 , wherein the second portion has a first bearing surface upon which the head of one of the fastening elements rests either directly or indirectly, and a second bearing surface opposite the first bearing surface.

11. The drive assembly as claimed in claim 10 , wherein the first bearing surface protrudes beyond the first portion in a first axial direction, and the second bearing surface protrudes beyond the first portion in a second axial direction that is opposite to the first axial direction.

12. The drive assembly as claimed in claim 1 , wherein the first portion of each vibration damping element is press-fitted to one of the sleeve elements.

13. The drive assembly as claimed in claim 1 , wherein the fastening means further comprises the carrier, and wherein the sleeve elements are disposed on the carrier.

14. The drive assembly as claimed in claim 13 , wherein each sleeve element is fitted within an opening formed in the carrier.

15. The drive assembly as claimed in claim 13 , wherein the sleeve elements are not all oriented parallel to each other.
