Abstract

A wheel suspension assembly ( 1 ) for a vehicle, having a spring damper ( 2 ), a first transverse link ( 4 ), which has a first transverse link strut ( 4 a ) and a second transverse link strut ( 4 b ), a second transverse link ( 5 ), a first tie rod ( 6 ), a second tie rod ( 7 ), a reversing lever ( 8 ), a hub carrier ( 9 ), a steering gear ( 10 ) and a pendulum support ( 11 ). Each transverse link ( 4, 5 ) has an end ( 12 ), on the hub carrier side, and two ends ( 13, 13 a, 13 b ), on the chassis side. The steering gear ( 10 ) is arranged in a plane with the first transverse link ( 4 ) and in a section between an end ( 13 a ) of the first transverse link strut ( 41 ) of the first transverse link ( 4 ), on the chassis side, and an end ( 13 b ) of the second transverse link strut ( 4 b ) of the first transverse link ( 4 ), on the chassis side.

First claim

The invention claimed is:

1. A wheel suspension assembly for a vehicle, the wheel suspension assembly comprising:
a spring damper,
a first transverse link having a first transverse link strut and a second transverse link strut,
a second transverse link,
a first tie rod,
a second tie rod,
a reversing lever,
a hub carrier,
a steering gear, and
a pendulum support,
each of the first and the second transverse links having an end on a hub carrier side and two ends on a chassis side,
the steering gear being arranged in a plane with the first transverse link, and
the steering gear being arranged in a section between an end of the first transverse link strut of the first transverse link on the chassis side and an end of the second transverse link strut of the first transverse link on the chassis side.

2. The wheel suspension assembly according to claim 1 , wherein the steering gear is operatively connected to the first tie rod, and the first tie rod is operatively connected to the reversing lever.

3. The wheel suspension assembly according to claim 1 , wherein the reversing lever has a double arched shape, a shape of the reversing lever is defined by a steering range and a shape of the hub carrier in a section of the reversing lever that is arranged in a plane with the hub carrier, as well as a suspension range and a shape of the first transverse link in a section of the reversing lever that is arranged in a plane with the first transverse link.

4. The wheel suspension assembly according to claim 1 , wherein the second tie rod is mounted on the hub carrier by a first ball pivot ( 20 ) and is mounted on the reversing lever by a second ball pivot, and rotational axes of the first and the second ball pivots of the second tie rod are skewed relative to one another.

5. The wheel suspension assembly according to claim 1 , wherein the second transverse link has a kinematics point on the hub carrier side, a web and an attachment point, the web extends from the kinematics point of the second transverse link on the hub carrier side to the attachment point of the second transverse link, and the second transverse link is connected to the pendulum support by the attachment point.

6. The wheel suspension assembly according to claim 5 , wherein the web of the second transverse link has a shape defined by the steering range of the hub carrier.

7. The wheel suspension assembly according to claim 5 , wherein the second transverse link has a connection point on the web by which the second transverse link is connected to the spring damper.

8. The wheel suspension assembly according to claim 1 , wherein the reversing lever is articulately mounted on the first transverse link.

9. The wheel suspension assembly according to claim 1 , wherein the first transverse link strut of the first transverse link has a curvature in a spatial direction, and the spatial direction is a vertical axis relative to a plane, which is spanned by the two ends on the chassis side and by the end of the first transverse link on the hub carrier side.

10. A wheel suspension assembly for a vehicle, a direction of straight forward travel of the vehicle being a vehicle longitudinal direction, the wheel suspension assembly comprising:
a spring damper,
a first tie rod,
a second tie rod,
a reversing lever,
a hub carrier,
a steering gear, and
a pendulum support;
a first transverse link having a first transverse link strut and a second transverse link strut;
a second transverse link;
each of the first and the second transverse links having a hub carrier side end and two chassis side ends;
the steering gear being arranged in a plane with the first ransverse link, and
the steering gear being arranged, with respect to the vehicle longitudinal direction, in an area between a chassis side end of the first transverse link strut of the first transverse link and a chassis side end of the second transverse link strut of the first transverse link.
