Abstract

A steering assembly for supporting a track system on a vehicle includes a steering knuckle, a first member being secured to a top side of the steering knuckle, a second member being secured to a bottom side of the steering knuckle, and a support frame. The support frame has a top portion being secured to the first member, a bottom portion being secured to the second member and being configured to be secured to the track system to support the track system on the vehicle, and a central portion extending between the top portion and the bottom portion of the support frame and being positioned solely on one of the front side and the rear side of the steering knuckle when the steering assembly is in use.

First claim

The invention claimed is:

1. A steering assembly for supporting a track system on a vehicle, the vehicle having a front and a rear and being drivable on terrain, the steering assembly comprising:
a) a steering knuckle having,
a bottom side facing towards the terrain when the steering assembly is in use,
a top side being opposite the bottom side,
a front side facing towards the front of the vehicle when the steering assembly is in use, and
a rear side being opposite the front side;

b) a first member being secured to the top side of the steering knuckle;
c) a second member being secured to the bottom side of the steering knuckle; and
d) a support frame having,
a top portion being secured to the first member,
a bottom portion being secured to the second member and being configured to be secured to the track system to support the track system on the vehicle when the steering assembly is in use, and
a central portion extending between the top portion and the bottom portion of the support frame and being positioned solely on one of the front side and the rear side of the steering knuckle.

2. The steering assembly of claim 1 , wherein the bottom portion of the support frame is securable to the track system by having means for securing the bottom portion to the track system, the means being positioned in the bottom portion.

3. The steering assembly of claim 2 , wherein the means for securing is means for securing the bottom portion of the support frame to at least two different track systems, the track system being one of the at least two different track systems.

4. The steering assembly of claim 1 , wherein the second member is positioned between the bottom side of the steering knuckle and the bottom portion of the support frame.

5. The steering assembly of claim 1 , wherein,
the bottom portion of the support frame is positioned below the bottom side of the steering knuckle; and
the second member is positioned between the bottom side of the steering knuckle and the bottom portion of the support frame.

6. The steering assembly of claim 1 , wherein the central portion of the support frame laterally flares from the top portion to the bottom portion.

7. The steering assembly of claim 1 , wherein,
the bottom portion of the support frame has,
a top surface facing the bottom side of the steering knuckle, and
a bottom surface opposite the top surface;

the second member has a mating surface that is in contact with the top surface of the bottom portion of the support frame;
a first plurality of holes sized to receive a first plurality of threaded fasteners extends from the bottom surface into the second member; and
at least a portion of each hole of the first plurality of holes that is in the second member is threaded to mateably receive therein a threaded fastener of the first plurality of threaded fasteners.

8. The steering assembly of claim 7 , wherein,
the bottom surface of the bottom portion of the support frame is larger than the mating surface of the second member;
a second plurality of holes extends from the bottom surface toward the top surface of the bottom portion of the support frame; and
the second plurality of holes is threaded to mateably receive therein a second plurality of threaded fasteners.

9. The steering assembly of claim 8 , wherein at least one of the first plurality of holes and the second plurality of holes defines at least two different hole patterns for securement of the bottom portion of the support frame to at least two different track systems.

10. The steering assembly of claim 1 , further comprising at least one of,
a first shim positioned between the first member and the support frame; and
a second shim positioned between the second member and the support frame.

11. The steering assembly of claim 1 , wherein the first member is a block of metallic material that has a first surface that is secured to the top side of the steering knuckle, and a second surface that extends upward from the first surface and is secured to the top portion of the support frame.

12. The steering assembly of claim 1 , wherein,
the first member is secured to the top side of the steering knuckle with a first plurality of threaded fasteners;
the second member is secured to the bottom side of the steering knuckle with a second plurality of threaded fasteners;
the top portion of the support frame is secured to the first member with a third plurality of threaded fasteners; and
the bottom portion of the support frame is secured to the second member with a fourth plurality of threaded fasteners.
