Abstract

An axle alignment system for an axle assembly. The axle alignment system may include a bracket assembly and an alignment plate. The alignment plate may be moveably disposed on the bracket assembly with one or more fasteners that may move along one or more slots that may be provided with the bracket assembly and/or the alignment plate.

First claim

What is claimed is:

1. An axle alignment system comprising:
an axle assembly;
a bracket assembly including:
a first plate defining a first elongate slot, a second elongate slot, and a clearance hole, and
a second plate disposed proximate the first plate, the second plate defining a third elongate slot, a fourth elongate slot, and a pry feature;

an alignment plate disposed proximate the first plate that has a first opening disposed proximate the first elongate slot, a second opening disposed proximate the second elongate slot, and a third opening proximately aligned with the clearance hole;
a lower control arm that extends between the axle assembly and the bracket assembly; and
an upper control arm that extends between the axle assembly and the bracket assembly;
wherein the first elongate slot and the third elongate slot receive a first fastener that mounts the lower control arm to the bracket assembly and the second elongate slot and the fourth elongate slot receive a second fastener that mounts the upper control arm to the bracket assembly, wherein the alignment plate positions the first fastener along the first and third elongate slots and positions the second fastener along the second and fourth elongate slots to position the axle assembly with respect to the bracket assembly.

2. The axle alignment system of claim 1 wherein a pry bar extends through the third opening and the clearance hole and engages the pry feature.

3. The axle alignment system of claim 2 wherein force exerted by the pry bar on the alignment plate positions the first fastener with respect to the first elongate slot and the third elongate slot.

4. The axle alignment system of claim 2 wherein force exerted by the pry bar on the alignment plate positions the second fastener with respect to the second elongate slot and the fourth elongate slot.

5. The axle alignment system of claim 2 wherein force exerted by the pry bar on the alignment plate positions the first fastener with respect to the first elongate slot and the third elongate slot and positions the second fastener with respect to the second elongate slot and the fourth elongate slot.

6. The axle alignment system of claim 1 wherein the clearance hole is disposed between the first and second elongate slots.

7. The axle alignment system of claim 1 wherein the pry feature is disposed between the third and fourth elongate slots.

8. The axle alignment system of claim 1 wherein the first fastener extends through the first opening of the alignment plate and the second fastener extends through the second opening of the alignment plate.

9. The axle alignment system of claim 1 wherein the third opening is disposed between the first opening and the second opening.

10. The axle alignment system of claim 1 wherein force exerted by a pry bar on the alignment plate moves the alignment plate and at least one of the lower control arm and the upper control arm relative to the bracket assembly.

11. The axle alignment system of claim 1 wherein a major axis of the first elongate slot extends from a first end of the first elongate slot to a second end of the first elongate slot such that the major axis of the first elongate slot is longer than a minor axis of the first elongate slot.

12. The axle alignment system of claim 11 wherein a major axis of the second elongate slot extends from a first end of the second elongate slot to a second end of the second elongate slot such that the major axis of the second elongate slot is longer than a minor axis of the second elongate slot.

13. The axle alignment system of claim 12 wherein the minor axes of the first and second elongate slots are disposed substantially perpendicular to the major axes of the first and second elongate slots, respectively.

14. The axle alignment system of claim 11 wherein major axes of the first opening and second opening of the alignment plate extend at an angle with respect to the lower control arm and the upper control arm.

15. The axle alignment system of claim 14 wherein the major axis of the first opening is disposed substantially parallel to a major axis of the second opening.

16. The axle alignment system of claim 1 wherein the first elongate slot is disposed substantially parallel to the second elongate slot.

17. The axle alignment system of claim 1 wherein force exerted by a tool on the alignment plate translates the first fastener along the first elongate slot and the first opening.

18. The axle alignment system of claim 17 wherein force exerted by the tool on the alignment plate translates the second fastener along the second elongate slot and the second opening.
