Abstract

A wheel suspension unit for a motor vehicle having a longitudinal link, having a first end for pivotable vehicle-side connection, a second end for connection to a wheel carrier, and a blade-like link portion resilient in the direction of the transverse axis (Y) and rigid transversely relative thereto. The wheel suspension reduces the number of components by providing a longitudinal link having a resilient portion resilient toward the longitudinal axis (X), wherein the longitudinal link is at least partially produced from a fiber-reinforced plastics material.

First claim

What is claimed is:

1. A wheel suspension unit for a motor vehicle comprising:
a longitudinal link having a first end for pivotable vehicle-side connection, a second end for connection to a wheel carrier, and a blade-like link portion resilient in a direction of a transverse axis and rigid transversely relative thereto; and
said longitudinal link has a resilient portion resilient in a direction of a longitudinal axis, wherein the longitudinal link is at least partially produced from a fiber-reinforced plastics material wherein said resilient portion is constructed in a planar manner and extends parallel with a Y-Z axis plane and said blade-like link portion is constructed in a planar manner and extends parallel with a X-Z axis plane.

2. The wheel suspension unit of claim 1 wherein between said resilient portion and said blade-like link portion there is formed a planar transition portion turned in a helix-like manner and extending adjacent to said resilient portion and parallel with said Y-Z axis plane and extends adjacent to the blade-like link portion parallel with said X-Z axis plane.

3. The wheel suspension unit of claim 1 wherein said longitudinal link has at said first end a non-resilient bearing for vehicle-side connection.

4. The wheel suspension unit of claim 3 wherein the non-resilient bearing is at least partially formed integrally with said resilient portion.

5. The wheel suspension unit of claim 1 wherein a wheel carrier is constructed integrally with said longitudinal link and said longitudinal link merges at the second end into said wheel carrier.

6. A wheel suspension comprising:
a longitudinal link formed of a fiber-reinforced material having a first end and a second end; and
said longitudinal link including a blade-like link portion resilient in a transverse axis and rigid in a longitudinal axis and a resilient portion resilient in said longitudinal axis and rigid in said transverse axis wherein the resilient portion is substantially planar and extends parallel with a transverse and vertical axis plane and the blade-like link portion is substantially planar and extends parallel with a longitudinal and vertical axis plane.

7. The wheel suspension of claim 6 including said resilient portion arranged adjacent to said first end and said blade-like portion arranged adjacent to a second end, said second end adjacent a wheel carrier.

8. The wheel suspension of claim 6 including a planar transition portion curved in a helix and extending between the resilient portion and the blade-like link portion.

9. The wheel suspension of claim 6 including a wheel carrier forming an integral portion of the longitudinal link adjacent said second end.

10. A wheel suspension comprising:
a longitudinal link formed of a fiber-reinforced material having a first end and a second end;
said longitudinal link including a blade-like link portion resilient in a transverse axis and rigid in a longitudinal axis and a resilient portion resilient in said longitudinal axis and rigid in said transverse axis;
a planar transition portion curved in a helix and extending between the resilient portion and the blade-like link portion;
a non-resilient bearing integrally connected to said resilient portion at said first end; and
a wheel carrier integrally connected to said blade-like portion at said second end.
