Abstract

The present invention provides a torsion attenuator for a vehicle frame having first and second longitudinal frame rails extending substantially parallel to a longitudinal axis. A torsion attenuator in accordance with one embodiment of the present invention includes first and second brackets coupled to the first and second frame rails, respectively. The torsion attenuator further includes a cable coupled at a first end to the first bracket, and coupled at a second end to the second bracket. A torsion attenuator in accordance with the present invention provides that the torsional loads are distributed to the frame rail system, rather than to the individual rails. Such a torsion attenuator may be especially advantageous in suspension systems that employ air springs.

Claims (23)

1. A torsion attenuator for a vehicle having first and second longitudinal frame rails extending substantially parallel to a longitudinal axis, said torsion attenuator comprising:

first and second brackets coupled to said first and second frame rails, respectively;

a cable coupled at a first end to said first bracket and at a second end to said second bracket; wherein the positions of said first end and said second end are fixed relative to said first and second frame rails, respectively;

wherein said first end of said cable further comprises a first threaded end, said second end of said cable further comprises a second threaded end, and wherein said first and second threaded ends are coupled to said first and second brackets, respectively.

2. The torsion attenuator of claim 1 , wherein said cable is coupled tautly between said first and second brackets.

3. The torsion attenuator of claim 1 , wherein said cable is generally transverse to said longitudinal axis.

4. The torsion attenuator of claim 1 , wherein said first and second brackets extend substantially vertical to said longitudinal axis.

5. A torsion attenuator for a vehicle having first and second longitudinal frame rails extending substantially parallel to a longitudinal axis, said torsion attenuator comprising:

first and second brackets coupled to said first and second frame rails, respectively;

a cable coupled at a first end to said first bracket and at a second end to said second bracket; wherein the positions of said first end and said second end are fixed relative to said first and second frame rails, respectively;

further comprising first and second spring seats coupled to said first and second frame rails, respectively, wherein said first and second brackets extend from first and second spring seats.

6. The torsion attenuator of claim 5 , wherein said cable is coupled tautly between said first and second brackets.

7. The torsion attenuator of claim 5 , wherein said cable is generally transverse to said longitudinal axis.

8. The torsion attenuator of claim 5 , wherein said first and second brackets extend substantially vertical to said longitudinal axis.

9. A torsion attenuator for a vehicle having first and second longitudinal frame rails extending substantially parallel to a longitudinal axis, said torsion attenuator comprising:

first and second longitudinal reinforcement members, coupled to said first and second frame rails, respectively;

first and second brackets, coupled to said first and second reinforcement members, respectively; and

a cable coupled at a first end to said first bracket and at a second end to said second bracket.

10. The torsion attenuator of claim 9 , wherein said cable is coupled tautly between said first and second brackets.

11. The torsion attenuator of claim 9 , wherein said first end of said cable further comprises a first threaded end, said second end of said further comprises a second threaded end, and wherein said first and second threaded ends are coupled to said first and second brackets, respectively.

12. The torsion attenuator of claim 9 , wherein said cable is generally transverse to said longitudinal axis.

13. The torsion attenuator of claim 9 , wherein said first and second brackets extend substantially vertical to said longitudinal axis.

14. The torsion attenuator of claim 9 , further comprising first and second spring seats coupled to said first and second reinforcement members, respectively, wherein said first and second brackets extend from first and second spring seats.
