Abstract

A steering assembly includes a piston rod including internal threads positioned on an inner wall of a recess, an inner tie rod housing including external threads engaging with the internal threads, the inner tie rod housing adjustably connected to the piston rod, a tie rod including an inner tie rod having an end positioned at least partially in the inner tie rod housing, a retainer including a wall portion and a flange portion, the retainer positioned at least partially in the recess, the retainer including a protrusion extending from an outer surface of the wall portion and contacting the inner wall of the recess, which resists rotation of the retainer, and one or more fasteners releasably attaching the retainer to the inner tie rod housing.

Claims (30)

1 . A steering assembly, comprising:

a piston rod including internal threads positioned on an inner wall of a recess;

an inner tie rod housing including external threads engaging with the internal threads, the inner tie rod housing adjustably connected to the piston rod;

a tie rod including an inner tie rod having an end positioned at least partially in the inner tie rod housing;

a retainer including a wall portion and a flange portion, the retainer positioned at least partially in the recess, the retainer including a protrusion extending from an outer surface of the wall portion and contacting the inner wall of the recess, which resists rotation of the retainer; and

one or more fasteners releasably attaching the retainer to the inner tie rod housing.

2 . The steering assembly of claim 1 , wherein the retainer resists rotation of the inner tie rod housing.

3 . The steering assembly of claim 1 , wherein the retainer is positioned adjacent to the inner tie rod housing.

4 . The steering assembly of claim 1 , wherein the inner wall of the recess includes an indentation corresponding to the protrusion of the retainer.

5 . The steering assembly of claim 1 , wherein the retainer has a larger diameter than the inner tie rod housing and the inner wall of the recess includes a step having a larger diameter for the retainer.

6 . The steering assembly of claim 1 , wherein the flange portion includes one or more slots which the one or more fasteners pass through and thread into one or more apertures in the inner tie rod housing.

7 . The steering assembly of claim 1 , wherein the retainer includes an inner groove in an inner surface of the wall portion.

8 . The steering assembly of claim 1 , wherein the retainer includes an outer groove in the outer surface for receiving a seal.

9 . The steering assembly of claim 1 , wherein the inner tie rod housing retains the end of the inner tie rod within the recess of the piston rod.

10 . The steering assembly of claim 1 , wherein the one or more fasteners are positioned around a circumference of the retainer.

11 . A work vehicle including a steering assembly, comprising:

a piston rod including internal threads positioned on an inner wall of a recess;

an inner tie rod housing including external threads engaging with the internal threads, the inner tie rod housing adjustably connected to the piston rod;

a tie rod including an inner tie rod having an end positioned at least partially in the inner tie rod housing;

a retainer including a wall portion and a flange portion, the retainer positioned at least partially in the recess, the retainer including a protrusion extending from an outer surface of the wall portion and contacting the inner wall of the recess, which resists rotation of the retainer; and

one or more fasteners releasably attaching the retainer to the inner tie rod housing.

12 . The work vehicle of claim 11 , wherein the retainer resists rotation of the inner tie rod housing.

13 . The work vehicle of claim 11 , wherein the retainer is positioned adjacent to the inner tie rod housing.

14 . The work vehicle of claim 11 , wherein the inner wall of the recess includes an indentation corresponding to the protrusion of the retainer.

15 . The work vehicle of claim 11 , wherein the retainer has a larger diameter than the inner tie rod housing and the inner wall of the recess includes a step having a larger diameter for the retainer.

16 . The work vehicle of claim 11 , wherein the flange portion includes one or more slots which the one or more fasteners pass through and thread into one or more apertures in the inner tie rod housing.

17 . The work vehicle of claim 11 , wherein the retainer includes an inner groove in an inner surface of the wall portion.

18 . The work vehicle of claim 11 , wherein the retainer includes an outer groove in the outer surface for receiving a seal.

19 . The work vehicle of claim 11 , wherein the inner tie rod housing retains the end of the inner tie rod within the recess of the piston rod.

20 . The work vehicle of claim 11 , wherein the one or more fasteners are positioned around a circumference of the retainer.
