Abstract

A wheel suspension for a vehicle including a carrier having a rotatably mounted bearing element. A spring damper strut connects to the carrier and the vehicle structure. A transverse control arm connects to the carrier at one end and at the other end to the vehicle structure. A control member connects to the carrier and the transverse control arm. The control member arranged relative to the transverse control arm such that a force application line of the control member is inclined toward a transverse control arm axis defined by a point of articulation of the transverse control arm on the structure side and a point of articulation of the transverse control arm on the carrier side wherein the force application line and the transverse control arm axis intersect between the points of articulation of the transverse control arm on the structure side and the carrier side.

First claim

What is claimed is:

1. A vehicle wheel suspension comprising:
a bearing element;
a carrier, said bearing element rotatably mounted on said carrier;
a spring damper strut connected to said carrier and supported on a vehicle structure;
a transverse control arm connected to the carrier and to the vehicle structure;
a control member connected at one end to the carrier and at the other end to the transverse control arm, said control member arranged relative to the transverse control arm such that in a front view of the control member and the transverse control arm, a force application line of the control member is inclined toward a transverse control arm axis defined by a point of articulation of the transverse control arm on the vehicle structure side and a point of articulation of the transverse control arm on the carrier side, such that a point of intersection of the force application line of the control member and the transverse control arm axis in a predetermined static position is between the point of articulation of the transverse control arm on the structure side and the point of articulation of the transverse control arm on the carrier side, between the end of the control member connected to the carrier and the point of articulation of the transverse control arm on the carrier side, and not between the end of the control member connected to the control arm and the end of the control member connected to the carrier, wherein between includes the respective ends of the control member.

2. The wheel suspension of claim 1 wherein the control member is arranged relative to the transverse control arm such that, in a plan view of the control member and the transverse control arm, the force application line of the control member intersects the point of articulation of the transverse control arm on the structure side.

3. The wheel suspension of claim 1 wherein the control member is arranged relative to a vehicle longitudinal direction in front of the transverse control arm.

4. The wheel suspension of claim 1 wherein the control member has an elongated rod-shaped configuration.

5. The wheel suspension of claim 1 wherein the control member is connected to the carrier via a ball joint.

6. The wheel suspension of claim 1 wherein the control member is connected to the transverse control arm via a ball joint.

7. A vehicle wheel suspension comprising:
a transverse control arm having first and second points of articulation and a control arm axis extending between said first and second points of articulation;
a carrier connected to said transverse control arm at said second point of articulation;
a control member having a force application line extending between first and second ends of said control member; and
said first end of said control member directly connected to said transverse control arm and said second end directly connected to said carrier such that in a static position the force application line and the control arm axis intersect at a point between said first and second points of articulation of said control arm, between said second end of said control member and said second point of articulation, and not between ends of said control member.

8. The wheel suspension of claim 7 wherein the control member is arranged relative to the transverse control arm such that, in a plan view of the control member and the transverse control arm, the force application line of the control member intersects a point of articulation of the transverse control arm on the structure side.

9. The wheel suspension of claim 7 wherein the control member is arranged relative to a vehicle longitudinal direction in front of the transverse control arm.

10. A vehicle wheel suspension comprising:
a transverse control arm having a structure side point of articulation and a carrier side point of articulation and a control arm axis extending between said structure side and carrier side points of articulation; and
a control member having a force application line extending between a first end of said control member connected to said control arm closer to said structure side point of articulation than said carrier side point of articulation and a second end connected to said carrier, a point of intersection between the control arm axis and the force application line located, in a static position, between the carrier side point of articulation and said second end of said control member and not between the first end of the control member and the second end of the control member.

11. The wheel suspension of claim 10 including:
said control member moving said carrier to a predetermined wheel recession position, said predetermined wheel recession position based on an initial position of said first end of said control member with respect to said control arm axis.

12. The wheel suspension of claim 10 wherein the control member is arranged relative to the transverse control arm such that, in a plan view of the control member and the transverse control arm, the force application line of the control member intersects a structure side point of articulation of the transverse control arm.

13. The wheel suspension of claim 10 wherein the control member is arranged relative to a vehicle longitudinal direction in front of the transverse control arm.

14. A vehicle wheel suspension comprising:
a transverse control arm having a structure side point of articulation and a carrier side point of articulation and a control arm axis extending between said structure side and carrier side points of articulation; and
a control member having a force application line extending between a first end of said control member connected to said control arm and a second end connected to said carrier;
said wheel suspension having a static position, a spring compression position and a spring rebound position;
the control arm axis and the force application line intersecting, in said static position, between said structure side and carrier side points of articulation and between the carrier side point of articulation and said second end of said control member;
the control arm axis and the force application line intersecting, in said spring rebound position, between said structure side and carrier side points of articulation and between the first end of the control member and the second end of the control member; and
the control arm axis and the force application line not intersecting, in said spring compression position, between said structure side and carrier side points of articulation.
