Abstract

A guard assembly is provided for use with a track assembly for a vehicle. The guard assembly includes a guard body having a rigid portion made of a first polymeric material and a flexible portion made of a second polymeric material different from the first polymeric material. The first polymeric material has a greater modulus of elasticity than the second polymeric material. A vehicle including a guard assembly, namely including a guard body is also contemplated.

First claim

What is claimed is:

1. A guard assembly for use with a track assembly for a vehicle, the guard assembly comprising:
a guard body comprising:
a rigid portion made of a first polymeric material; and
a flexible portion made of a second polymeric material different from the first polymeric material, the first polymeric material having a greater modulus of elasticity than the second polymeric material,

the flexible portion being configured to deform to a deformed state in response to the flexible portion contacting a shock absorber of a suspension assembly of the vehicle and to return to an undeformed state in response to the flexible portion no longer being in contact with the shock absorber.

2. The guard assembly of claim 1 , wherein:
the guard body has an inner lateral edge and an outer lateral edge; and
the flexible portion extends along at least a portion of the inner lateral edge of the guard body.

3. The guard assembly of claim 1 , wherein:
the guard body has an inner lateral end portion and an outer lateral end portion; and
the guard assembly further comprises:
an inner support member for connecting the guard body to a frame of the track assembly, the inner support member being connected to the inner lateral end portion of the guard body; and
an outer support member for connecting the guard body to the frame of the track assembly, the outer support member being connected to the outer lateral end portion of the guard body.

4. The guard assembly of claim 3 , wherein:
the inner support member is a first inner support member;
the guard assembly further comprises a second inner support member connected to the inner lateral end portion of the guard body;
each of the first and second inner support members comprises a rigid link having a first end and a second end;
the first end of each rigid link is affixed to the guard body; and
the second end of each rigid link is configured to be affixed to a frame of the track assembly.

5. The guard assembly of claim 3 , wherein the outer support member is made of polymeric material.

6. The guard assembly of claim 3 , wherein:
the outer support member has an upper portion and a lower portion;
the upper portion is connected to the outer lateral end portion of the guard body;
the lower portion is configured to be connected to a drive wheel support of the frame of the track assembly.

7. The guard assembly of claim 6 , further comprising an outer support connector that is configured to be mounted to the drive wheel support of the track assembly frame, the lower portion of the outer support member being configured to be fastened to the outer support connector.

8. The guard assembly of claim 1 , wherein:
the rigid portion of the guard body defines a notch along a lateral side thereof; and
the flexible portion of the guard body extends at least partly within the notch defined by the rigid portion.

9. A vehicle comprising:
a vehicle frame;
a motor supported by the vehicle frame;
a track assembly operatively connected to the vehicle frame, the track assembly comprising:
a track assembly frame;
an endless track having at least one row of drive features; and
a plurality of track-engaging wheels, including:
a drive wheel rotatably connected to the track assembly frame, the drive wheel being configured to engage the drive features of the endless track to rotate the endless track about the plurality of track-engaging wheels and thereby propel the vehicle; and
at least one idler wheel rotatably connected to the track assembly frame;

a suspension assembly operatively connecting the track assembly to the vehicle frame, the suspension assembly comprising a shock absorber;
and
a guard assembly connected to the track assembly, the guard assembly comprising:
a guard body positioned vertically above the endless track, at least a portion of the guard body extending over the drive wheel, the guard body being made of a first polymeric material and a second polymeric material different from the first polymeric material, the first polymeric material having a greater modulus of elasticity than the second polymeric material, the guard body comprising:
a rigid portion made of the first polymeric material; and
a flexible portion made of the second polymeric material, the flexible portion being longitudinally aligned with the shock absorber,
during use, the flexible portion deforms to a deformed state in response to the flexible portion contacting the shock absorber and returns to an undeformed state in response to the flexible portion no longer being in contact with the shock absorber;

and
at least one support member connecting the guard body to the track assembly frame.

10. The vehicle of claim 9 , wherein:
the guard body has an inner lateral edge and an outer lateral edge, the inner lateral edge being laterally closer to a longitudinal centerplane of the vehicle than the outer lateral edge; and
the flexible portion extends along at least a portion of the inner lateral edge of the guard body.

11. The vehicle of claim 9 , wherein the guard body spans at least a width of the endless track.

12. The vehicle of claim 9 , wherein the at least one support member of the guard assembly comprises:
an inner support member disposed on a lateral inner side of the track assembly; and
an outer support member disposed on a lateral outer side of the track assembly.

13. The vehicle of claim 12 , wherein:
the inner support member is a front inner support member;
the at least one support member further comprises a rear inner support member, the rear inner support member being disposed on the lateral inner side of the track assembly rearward of the front inner support member;

each of the front and rear inner support members comprises a rigid link having a first end and a second end;
the first end of each rigid link is affixed to the guard body; and
the second end of each rigid link is affixed to the track assembly frame.

14. The vehicle of claim 12 , wherein:
the track assembly frame comprises a drive wheel support rotatably supporting the drive wheel;
the outer support member is connected to the guard body and the drive wheel support;
the outer support member has an upper portion connected an outer lateral end portion of the guard body;
the outer support member has a lower portion connected to the drive wheel support of the track assembly frame; and
the guard assembly further comprises:
an outer support connector that is mounted to the drive wheel support of the track assembly frame, the lower portion of the outer support member being fastened to the outer support connector;
an outer support sealing member mounted between the outer support connector and the drive wheel support of the track assembly frame to seal an interior of the drive wheel support.

15. The vehicle of claim 12 , wherein:
the guard body has an inner lateral edge and an outer lateral edge, the inner lateral edge being laterally closer to a longitudinal centerplane of the vehicle than the outer lateral edge; and
the inner support member and the outer support member are disposed laterally between the inner and outer lateral edges of the guard body.

16. The vehicle of claim 9 , wherein:
the rigid portion of the guard body defines a notch along a lateral side thereof; and
the flexible portion of the guard body extends at least partly within the notch defined by the rigid portion.

17. The vehicle of claim 9 , wherein the guard body further extends over a portion of the endless track forward of the drive wheel.
