Abstract

A wheel guard includes a guard member disposed on a compactor wheel. The guard member has a first side having a first portion and a second portion. The second portion is offset from the first portion such that to define a first stepped recess therein. The guard member has a second side disposed opposite to the first side. The first portion has a first cross-sectional thickness and the second portion has a second cross-sectional thickness such that the second cross-sectional thickness is lesser than the first cross-sectional thickness. The guard member has a first top surface defined by the first portion, and a second top surface defined by the second portion and partially by the first portion. The second top surface is offset from the first top surface such that to define a second stepped recess therein. The wheel guard includes a base plate and a wear pad coupled thereto.

First claim

What is claimed is:

1. A wheel guard for use on a compactor wheel, the wheel guard comprising:
a guard member disposed on the compactor wheel, the guard member having:
a first end and a second end;
a first side having a first portion and a second portion, wherein the second portion is offset from the first portion such that the first portion and the second portion define a first stepped recess therein;
a second side disposed opposite to the first side;
the first portion having a first cross-sectional thickness and the second portion having a second cross-sectional thickness such that the second cross-sectional thickness is lesser than the first cross-sectional thickness;
a first top surface defined by the first portion; and
a second top surface defined by the second portion and partially by the first portion, wherein the second top surface is offset from the first top surface such that the first top surface and the second top surface define a second stepped recess therein;

a base plate overlaid upon and coupled to the second stepped recess; and
a wear pad coupled to the base plate.

2. The wheel guard of claim 1 , wherein the wear pad has an integral construction.

3. The wheel guard of claim 1 , wherein the wear pad has a modular construction.

4. The wheel guard of claim 3 , wherein the wear pad includes a plurality of wear pad pieces.

5. The wheel guard of claim 4 , wherein each wear pad piece of the plurality of wear pad pieces is coupled to the base plate through one or more of welding, a fastener, soldering, or brazing.

6. The wheel guard of claim 1 , wherein a hardness of the wear pad exceeds a hardness of the base plate and the guard member.

7. The wheel guard of claim 1 , wherein the second portion of the first side is adapted to mate with a second portion of a first side of another wheel guard.

8. The wheel guard of claim 1 , wherein the base plate has a geometrical profile complementary to a profile of the second top surface of the second portion of the guard member.

9. The wheel guard of claim 1 , wherein the wear pad has a geometrical profile complementary to a profile of the second top surface of the second portion of the guard member.

10. A compactor wheel comprising:
a rim having a circumferential surface, a first edge, and a second edge;
a plurality of cleats radially extending from the circumferential surface; and
a plurality of wheel guards secured between circumferentially adjacent cleats of the plurality of cleats provided proximate to the first edge of the rim, the plurality of wheel guards and the circumferentially adjacent cleats forming a barrier around the circumference of the rim, wherein each wheel guard of the plurality of wheel guards includes:
a guard member disposed on the compactor wheel, the guard member having:
a first end and a second end;
a first side having a first portion and a second portion, wherein the second portion is offset from the first portion such that the first portion and the second portion define a first stepped recess therein;
a second side disposed opposite to the first side;
the first portion having a first cross-sectional thickness and the second portion having a second cross-sectional thickness such that the second cross-sectional thickness is lesser than the first cross-sectional thickness; and
the first portion having a first top surface and the second portion having a second top surface, wherein the second top surface is offset from the first top surface such that the first top surface and the second top surface define a second stepped recess therein;

a base plate overlaid upon and coupled to the second stepped recess; and
a wear pad coupled to the base plate.

11. The compactor wheel of claim 10 , wherein the wear pad has an integral construction.

12. The compactor wheel of claim 10 , wherein the wear pad has a modular construction.

13. The compactor wheel of claim 12 , wherein the wear pad includes a plurality of wear pad pieces.

14. The compactor wheel of claim 13 , wherein each wear pad piece of the plurality of wear pad pieces is coupled to the base plate through one or more of welding, a fastener, soldering, or brazing.

15. The compactor wheel of claim 10 , wherein a hardness of the wear pad exceeds a hardness of the base plate and the guard member.

16. The compactor wheel of claim 10 , wherein the second portion of the first side is adapted to mate with a second portion of a first side of another wheel guard.

17. The compactor wheel of claim 10 , wherein the base plate has a geometrical profile complementary to a profile of the second top surface of the second portion of the guard member.

18. The compactor wheel of claim 10 , wherein the wear pad has a geometrical profile complementary to a profile of the second top surface of the second portion of the guard member.

19. A compactor comprising:
a frame;
a power source disposed on the frame;
an operator cabin disposed on the frame;
a plurality of compactor wheels adapted to propel the compactor on a ground surface, each compactor wheel of the plurality of compactor wheels including:
a rim having a circumferential surface, a first edge, and a second edge;
a plurality of cleats radially extending from the circumferential surface;
a plurality of wheel guards secured between circumferentially adjacent cleats of the plurality of cleats provided proximate the first edge of the rim, the plurality of wheel guards and the circumferentially adjacent cleats forming a barrier around the circumference of the rim, wherein each wheel guard of the plurality of wheel guards includes:
a guard member disposed on the compactor wheel, the guard member having:
a first end and a second end;
a first side having a first portion and a second portion, wherein the second portion is offset from the first portion such that the first portion and the second portion define a first stepped recess therein;
a second side disposed opposite to the first side;
the first portion having a first cross-sectional thickness and the second portion having a second cross-sectional thickness such that the second cross-sectional thickness is lesser than the first cross-sectional thickness; and
the first portion having a first top surface and the second portion having a second top surface, wherein the second top surface is offset from the first top surface such that the first top surface and the second top surface define a second stepped recess therein;

a base plate overlaid upon and coupled to the second stepped recess; and
a wear pad coupled to the base plate.

20. The compactor of claim 19 , wherein the wear pad has a modular construction.
