Abstract

A brake assembly for a wheel on a vehicle includes a brake disc, a caliper assembly operably coupled to the brake disc, a brake line fluidly coupled to the caliper assembly, and a brake shield positioned adjacent a portion of the caliper assembly. The brake shield includes a first arm positioned on a first side of a portion of the brake disc and a second arm positioned on a second side of the portion of the brake disc. The brake disc further includes a recess configured to receive a portion of the brake line.

Claims

1. A brake assembly for a wheel on a vehicle,

comprising:

a brake disc;

a caliper assembly operably coupled to the brake disc;

a brake line fluidly coupled to the caliper assembly; and

a brake shield positioned adjacent a portion of the caliper assembly and including a first arm positioned on a first side of a portion of the brake disc and a second arm positioned on a second side of the portion of the brake disc, and the brake shield being configured to conceal a portion of the brake line at least from a top view.

2. The brake assembly of claim 1, further comprising brake pads operably coupled to the brake line, and the first and second arms of the brake shield are positioned upstream of the brake pads in a forward rotation direction of the wheel.

3. The brake assembly of claim 2, wherein the first and second arms are configured to remove mud from the brake disc.

4. The brake assembly of claim 1, wherein the brake shield is positioned upstream of the caliper assembly in a forward rotation direction of the wheel.

5. The brake assembly of claim 1, wherein the brake shield includes a plurality of parallel projections extending radially outward relative to the caliper assembly.

6. The brake assembly of claim 1, wherein the brake shield is integral with a caliper carrier of the caliper assembly.

7. The brake assembly of claim 1, wherein the brake shield is removably coupled to the caliper assembly.

8. A brake assembly for a wheel, comprising:

a brake disc;

a caliper assembly operably coupled to the brake disc and including a caliper carrier portion and a brake pad portion;

a brake line fluidly coupled to the brake disc and configured to move the brake pad portion of the caliper assembly relative to the brake disc; and

a brake shield positioned adjacent a portion of the caliper assembly and including a plurality of projections extending radially outward from an outer surface of the brake shield, and at least one of the projections is angled relative to a rotational plane of the wheel, wherein an upstream end of each projection is positioned outwardly from a corresponding downstream end of the projection in a direction of forward wheel rotation.

9. The brake assembly of claim 8, wherein the at least one projection is generally parallel to an axis of rotation of the wheel.

10. The brake assembly of claim 8, wherein the at least one projection is angled relative to an axis of rotation of the wheel.

11. The brake assembly of claim 8, wherein each of the projections is parallel to each other at an outer portion of the brake shield.

12. The brake assembly of claim 8, wherein the brake line is positioned within a portion of the brake shield.

13. A utility vehicle, comprising:

a plurality of ground-engaging members including at least one front ground-engaging member and at least one rear ground-engaging member, and each of the plurality of ground-engaging members includes a rim;

a frame supported by the plurality of ground-engaging members;

a powertrain assembly configured to provide motive power to at least a portion of the plurality of ground-engaging members;

a brake assembly operably coupled to the at least one front ground-engaging member and including a brake disc, a caliper assembly, a brake line fluidly coupled to the caliper assembly, and a brake shield coupled to the caliper assembly and having a scraping surface configured to remove accumulations of debris from the brake disc and the rim, wherein the scraping device includes at least a portion arranged radially outward from the brake disc and at least a portion is arranged on a side of the brake disc.

14. The utility vehicle of claim 13, wherein the brake line is positioned within a portion of the brake shield.

15. The utility vehicle of claim 13, wherein the scraping surface is defined by a plurality of projections extending radially outward relative to the caliper assembly and the projections are angled relative to a rotational plane of the at least one front ground-engaging member.

16. The utility vehicle of claim 15, wherein the plurality of projections are parallel to each other and are configured to remove accumulations from the rim.

17. The utility vehicle of claim 13, wherein the brake shield is positioned upstream of the caliper assembly in a forward rotation direction of the at least one front ground-engaging member.

18. The utility vehicle of claim 13, wherein the brake shield is integral with a caliper carrier of the caliper assembly.

19. The utility vehicle of claim 13, further comprising a second brake assembly operably coupled to the at least one rear ground-engaging member and including a brake disc, a caliper assembly operably coupled to the brake disc, a brake line fluidly coupled to the caliper assembly, and a brake line shield configured to receive a portion of the brake line adjacent the brake disc.
