Abstract

A steering gear pad for a steering gear of a sector and pinion or rack and pinion steering system. The steering gear pad has a plastic body and a rim with a plurality of plastic gear teeth positioned adjacent a plurality of metal gear teeth on a sector gear or rack mounted to a support plate. The plastic gear teeth may have width dimensions larger than the metal gear teeth. One or more resilient spacers urge the steering gear out of contact with the support plate.

First claim

The invention claimed is:

1. An apparatus comprising:
a steering gear pad attached to a steering gear and having a plurality of steering gear pad teeth along a rim portion corresponding to a plurality of steering gear teeth along a rim portion of the steering gear; and
a plurality of spacers extending from the steering gear pad and spacing the steering gear away from a support plate to which the steering gear is pivotably mounted;
the steering gear pad teeth each have a greater width than the steering gear teeth.

2. The apparatus of claim 1 wherein the spacers extend from opposing first and second ends of the steering gear pad that are deflected away from the steering gear and the steering support plate while the spacers contact the support plate.

3. The apparatus of claim 1 wherein the steering gear pad has a partially hollow plastic body and opposing ends having less cross section area than the partially hollow plastic body.

4. The apparatus of claim 1 wherein the spacers are bosses on the steering gear pad and extend through openings in the steering gear.

5. An apparatus comprising:
a steering gear pad having a plastic body and a rim with a plurality of plastic gear teeth positioned adjacent a plurality of metal gear teeth on a steering gear mounted to a support plate; the plastic gear teeth having width dimensions larger than the metal gear teeth; and
at least one resilient spacer urging the steering gear out of contact with the support plate:
wherein the resilient spacer is a boss on an end portion of the steering gear pad.

6. The apparatus of claim 5 further comprising at least one drag link pivotably attached to the steering gear.

7. The apparatus of claim 5 wherein the steering gear pad is secured to the steering gear with mechanical fasteners.

8. The apparatus of claim 5 wherein the rim of the steering gear pad is inclined downwardly.

9. An apparatus comprising:
a steering gear mounted to a support plate and having a plurality of steering gear teeth meshed to a pinion gear on a steering shaft; and
a steering gear pad attached to the steering gear and having a plurality of steering gear pad teeth aligned with and adjacent the steering gear teeth, having larger dimensions than the steering gear teeth, and having a plurality of aligning members and spacers extending through openings in the steering gear; at least one of the spacers limiting contact between the steering gear and the support plate.

10. The apparatus of claim 9 wherein the spacers extend from end portions of the steering gear pad having less cross section area than a body portion of the steering gear pad, so that the end portions can deflect when the spacers contact the support plate.
