Abstract

A suspension system of the present invention pivotally supports a wheel of a motor vehicle. An upper control arm and a lower control arm are cooperable with a spindle, which supports the wheel. A vibration damper is cooperable with the upper control arm. A link interconnects the lower control arm and one of the terminal ends of the vibration damper thereby defining a common axis bisecting the link. The vibration damper moves along the common axis to absorb vibration transferred from a road surface and through the wheel.

Claims (28)

1. A suspension system for pivotally supporting a wheel of a motor vehicle, said suspension system comprising:

an upper control arm;

a lower control arm cooperable with a spindle defining a rotational axis, said spindle supporting the wheel;

a vibration damper having first and second terminal ends with said first terminal ends being cooperable with said upper control arm; and

a link having a monolithic construction and a generally uniform thickness throughout interconnecting said lower control arm and said second terminal end of said vibration damper with said link and said vibration damper defining a common axis bisecting said link and extending in a direction different from the direction of said rotational axis with said vibration damper being movable along said common axis for absorbing vibration transferred from a road surface and through the wheel.

2. A suspension system as set forth in claim 1 wherein said link is stamped from a blank formed from metal, metal alloys, and combination thereof.

3. A suspension system as set forth in claim 2 wherein said link is further defined by a neck portion having a circular cross section and a pair of opposing legs extending from said neck portion to distal ends with each said distal end defining an opening to receive a fastener for affixing said link to said lower control arm.

4. A suspension system as set forth in claim 3 wherein said neck portion includes terminal edges and a pair of lips extending from each of said terminal edges to receive a connector extending therethrough as said neck portion circumscribes and engages said terminal end of said vibration damper.

5. A suspension system as set forth in claim 4 wherein each of said legs defines a periphery having a flange for strengthening said link and said flange becomes tapered proximate to said distal end of each of said legs.

6. A suspension system as set forth in claim 4 wherein one of said periphery defines a generally linear geometry.

7. A suspension system as set forth in claim 4 wherein one of said periphery defines a generally curvelinear geometry.

8. A suspension system as set forth in claim 5 including a reinforcement rib formed into said leg and extending from said neck portion to said distal end.

9. A suspension system as set forth in claim 8 wherein said reinforcement rib is further formed into said neck portion thereby tapering in an opposite direction from said distal end to increase strength of said link.

10. A suspension system as set forth in claim 9 wherein said reinforcement rib bridges said neck portion and said legs and presents a first width as said reinforcement rib extends from said distal end to said neck portion and a second width as said leg transforms to said neck portion and a third width as said reinforcement rib further tapers onto said neck portion.

11. A suspension system for pivotally supporting a wheel of a motor vehicle and including an upper control arm, a lower control arm cooperable with a spindle defining a rotational axis and supporting the wheel, said suspension system comprising:

a vibration damper having first and second terminal ends with said first terminal end being cooperable with the upper control arm; and

a link having a monolithic construction and a generally uniform thickness throughout for interconnecting the lower control arm and said second terminal end of said vibration damper with said link and said vibration damper defining a common axis bisecting said link and extending in a direction different from the direction of the rotational axis with said vibration damper being movable along said common axis for absorbing vibration transferred from a road surface and through the wheel.

12. A suspension system as set forth in claim 11 wherein said link is further defined by a neck portion having a generally circular cross section for receiving said vibration damper.

13. A suspension system as set forth in claim 11 wherein said link includes a reinforcement rib deformed into each of said legs thereby preventing said legs from bending as said strut device absorbs vibration transferred from the road surface and through the wheel.

14. A suspension system as set forth in claim 11 wherein said link is stamped from a blank formed from metal, metal alloys, and combination thereof.

15. A suspension system as set forth in claim 11 wherein said neck portion includes terminal edges and a seam extending therebetween, said seam being adapted to receive a connector for securing said link to said vibration damper.

16. A suspension system as set forth in claim 11 wherein each of said legs presents a face having opposed peripheral edges extending outwardly from said face and tapering proximate said distal end to present said distal end having a generally flat cross section.

17. A suspension system as set forth in claim 11 wherein said peripheral edges are parallel to one another.

18. A suspension system as set forth in claim 11 wherein one of said peripheral edges is generally linear.

19. A suspension system as set forth in claim 11 wherein said face of said leg is curvelinear.

20. A suspension system as set forth in claim 11 wherein said face of said leg is non-planar.

21. A suspension system as set forth in claim 11 wherein said reinforcement rib is further deformed into said neck portion tapering away from said distal end to increase strength of said link.

22. A suspension system as set forth in claim 11 wherein said reinforcement rib presents a first width as said reinforcement rib extends from said distal end to said neck portion and a second width as said leg transforms to said neck portion and a third width as said reinforcement rib further tapers onto said neck portion.
