Abstract

A wheel suspension, having a wheel mount, on which at least one wheel is to be rotatably mounted, having at least one upper suspension arm flexibly coupled with the wheel mount for guiding the wheel, having at least one lower suspension arm flexibly coupled with the wheel mount for guiding the wheel, and having at least one strut, which has at least one bearing point to be arranged fixed on the vehicle body, via which the strut is to be articulated at least indirectly on the vehicle body of the motor vehicle, wherein one of the suspension arms is flexibly coupled with the strut, and wherein the one suspension arm is free of a bearing point to be arranged fixed on the vehicle body, via which the one suspension arm is to be mounted on the vehicle body.

First claim

The invention claimed is:

1. A wheel suspension for a motor vehicle, comprising:
a wheel mount on which a wheel of the motor vehicle is to be rotatably mounted;
a strut having a first bearing point that is fixed on a vehicle body of the motor vehicle, via which the strut is articulated at least indirectly on the vehicle body;
a first suspension arm flexibly coupled with the wheel mount for guiding the wheel, and flexibly coupled with the strut, the first suspension arm being free of a bearing point that is fixed on the vehicle body for mounting the first suspension arm on the vehicle body; and
a second suspension arm flexibly coupled with the wheel mount for guiding the wheel, and flexibly attached to the strut by a coupling, the coupling being flexibly coupled with both the second suspension arm and the strut;
wherein the strut has a second bearing point fixed on the strut, the second bearing point being arranged in a vehicle-vertical direction below the first bearing point;
wherein the strut has a third bearing point fixed on the strut, the third bearing point being arranged in a vehicle-vertical direction below the first bearing point;
wherein the first suspension arm is mounted on the strut via the second bearing point; and
wherein the coupling is mounted on the strut via the third bearing point.

2. The wheel suspension as claimed in claim 1 , wherein the coupling is mounted directly on the second suspension arm.

3. The wheel suspension as claimed in claim 2 , wherein the coupling is mounted directly on the strut.

4. The wheel suspension as claimed in claim 2 , wherein the first suspension arm is mounted directly on the strut.

5. The wheel suspension as claimed in claim 2 , wherein:
the second suspension arm has at least one further bearing point that is fixed on the vehicle body, via which the second suspension arm is articulated at least indirectly on the vehicle body.

6. The wheel suspension as claimed in claim 2 , wherein the first suspension arm is mounted directly on the wheel mount.

7. The wheel suspension as claimed in claim 1 , wherein the coupling is mounted directly on the strut.

8. The wheel suspension as claimed in claim 7 , wherein the first suspension arm is mounted directly on the strut.

9. The wheel suspension as claimed in claim 7 , wherein:
the second suspension arm has at least one further bearing point that is fixed on the vehicle body, via which the second suspension arm is articulated at least indirectly on the vehicle body.

10. The wheel suspension as claimed in claim 1 , wherein the first suspension arm is mounted directly on the strut.

11. The wheel suspension as claimed in claim 10 , wherein:
the second suspension arm has at least one further bearing point that is fixed on the vehicle body, via which the second suspension arm is articulated at least indirectly on the vehicle body.

12. The wheel suspension as claimed in claim 1 , wherein:
the second suspension arm has at least one further bearing point that is fixed on the vehicle body, via which the second suspension arm is articulated at least indirectly on the vehicle body.

13. The wheel suspension as claimed in claim 1 , wherein the first suspension arm is mounted directly on the wheel mount.

14. The wheel suspension as claimed in claim 1 , wherein the second suspension arm is mounted directly on the wheel mount.

15. The wheel suspension as claimed in claim 1 , wherein:
the second suspension arm has two suspension arm parts spaced apart from one another;
each of the two suspension arm parts is flexibly coupled with the wheel mount and to at least one connecting part arranged between and rigidly connected to the suspension arm parts, the at least one connecting part extending obliquely or perpendicularly to the suspension arm parts;
the suspension arm parts are connected to one another via the at least one connecting part; and
the coupling is mounted via the connecting part on the second suspension arm.

16. The wheel suspension as claimed in claim 1 , wherein:
the first suspension arm is an upper suspension arm; and
the second suspension arm is a lower suspension arm.

17. The wheel suspension as claimed in claim 1 , wherein:
the first suspension arm is a lower suspension arm; and
the second suspension arm is an upper suspension arm.

18. A holding arrangement comprising:
at least one wheel on a vehicle body of a motor vehicle, in which the wheel is held flexibly on the vehicle body via a wheel suspension, including a wheel mount, on which the wheel is rotatably mounted;
a strut having a first bearing point that is fixed on the vehicle body, via which the strut is articulated at least indirectly on the vehicle body;
a first suspension arm flexibly coupled with the wheel mount for guiding the wheel and flexibly coupled with the strut, the first suspension arm being free of a bearing point that is fixed on the vehicle body for mounting the first suspension arm on the vehicle body; and
a second suspension arm flexibly coupled with the wheel mount for guiding the wheel and flexibly attached to the strut by a coupling, the coupling being flexibly coupled with both the second suspension arm and the strut;
wherein the strut has a second bearing point fixed on the strut, the second bearing point being arranged in a vehicle-vertical direction below the first bearing point;
wherein the strut has a third bearing point fixed on the strut, the third bearing point being arranged in a vehicle-vertical direction below the first bearing point;
wherein the first suspension arm is mounted on the strut via the second bearing point; and
wherein the coupling is mounted on the strut via the third bearing point.
