Abstract

A carrier bearing assembly can include a bracket comprising a first end, a second end, a first face extending between the first end and the second end width, and a second face opposite the first face. An opening can be formed completely through the bracket and extend from the first face to the second face. A bearing can be disposed within the opening and an angle between a centerline of the bearing and a centerline of the bracket can be in a range of 85-89° or 91-95°. First and second mounting structures offset from the opening can be for coupling the carrier bearing assembly to the frame of the UTV, and the centerline of the bracket can pass through a center of the first mounting structure and a center of the second mounting structure.

Claims

1. A carrier bearing assembly for attaching to a frame of a utility terrain vehicle (UTV), comprising:

a bracket comprising a first end, a second end, a width extending between the first end and the second end in an x-direction, a first face extending between the first end and the second end along the width, and a second face opposite the first face extending between the first end and the second end along the width of the bracket;

an opening formed completely through the bracket and extending from the first face to the second face in a y-direction;

a bearing disposed within the opening and an angle between a centerline of the bearing and a centerline of the bracket being in a range of 85-89°

or 91-95°

, the bearing directly contacting the bracket;

a first mounting structure offset from the opening for coupling the carrier bearing assembly to the frame of the UTV; and

a second mounting structure offset from the opening for coupling the carrier bearing assembly to the frame of the UTV, and

wherein the centerline of the bracket passes through a center of the first mounting structure and a center of the second mounting structure as viewed in an x-y plane.

2. The carrier bearing assembly of claim 1, wherein:

the first mounting structure comprises a first opening through the bracket and a first bolt disposed through the first opening, the first bolt being adapted to be aligned with a first hole in the frame of the UTV; and

the second mounting structure comprises a second opening through the bracket and a second bolt disposed through the second opening, the second bolt being adapted to be aligned with a second hole in the frame of the UTV,

wherein a center of the first mounting structure is defined by a center of the first bolt as viewed in the x-y plane, and

wherein a center of the second mounting structure is defined by a center of the second bolt as viewed in the x-y plane.

3. The carrier bearing assembly of claim 2, wherein the first opening of the first mounting structure is formed as a slotted opening.

4. The carrier bearing assembly of claim 3, wherein:

the slotted opening comprises an elongate, plus, circular, or square shape; and

a cross-sectional area of the slotted opening is greater than or equal to 1.2 times a cross-sectional area of the first bolt.

5. The carrier bearing assembly of claim 2, wherein:

the bracket comprises an upper unitary machined bracket component comprising the opening and the bearing; and

a lower unitary machined bracket component comprising the first opening through the bracket with the first bolt disposed through the first opening, and the second opening through the bracket and the second bolt disposed through the second opening.

6. The carrier bearing assembly of claim 5, wherein a slotted opening is formed in the bracket within a common footprint of the upper unitary machined bracket and the lower unitary machined bracket.

7. The carrier bearing assembly of claim 2, wherein the bracket comprises a machined aluminum bracket.

8. The carrier bearing assembly of claim 1, wherein the carrier bearing is fastened over or under the frame of the UTV.

9. The carrier bearing assembly of claim 1, wherein the angle between the centerline of the bearing and a centerline of the bracket is in a range of 85-88.5°

or 91.5-95°

.

10. The carrier bearing assembly of claim 9, wherein the bracket comprises a machined aluminum bracket.

11. The carrier bearing assembly of claim 1, wherein the bracket comprises a machined aluminum bracket.

12. A carrier bearing assembly for attaching to a frame of a utility terrain vehicle (UTV), comprising:

a bracket comprising a first end, a second end, a width extending between the first end and the second end, a first face extending between the first end and the second end along the width, and a second face opposite the first face extending between the first end and the second end along the width of the bracket, the bracket further comprising an upper bracket component coupled to a separate lower bracket component;

an opening formed completely through the bracket and extending from the first face to the second face;

a bearing disposed within the opening, the bearing being disposed within the opening without a rubber gasket completely encircling the bearing; and

at least one mounting structure for coupling the carrier bearing assembly to the frame of the UTV using original bolt holes in the frame of the UTV for receiving a stock carrier bearing assembly;

wherein the bracket is configured to allow an angle in a range of 85-89°

or 91-95°

relative to a centerline of the bearing and a centerline of the bracket.

13. The carrier bearing assembly of claim 12, wherein the at least one mounting structure further comprises:

a first bolt adapted to be aligned with a first hole in the frame of the UTV; and

a second bolt adapted to be aligned with a second hole in the frame of the UTV,

wherein a centerline of the bracket passes through a center of the first bolt and a center of the second bolt, as viewed in an x-y plane, such that the angle is measured between a centerline of the bearing and a centerline of the bracket and is in a range of 85°

-88.5°

or 91.5°

-95°

.

14. The carrier bearing assembly of claim 13, wherein the upper bracket portion is bolted to the lower bracket portion.

15. The carrier bearing assembly of claim 13, wherein:

the upper bracket component comprises an upper unitary machined bracket component comprising the opening and the bearing; and

the lower bracket component comprises a unitary machined bracket component comprising openings through which the first bolt and the second bolt are disposed.

16. The carrier bearing assembly of claim 15, wherein at least one slotted opening is formed within a common footprint of the upper unitary machined bracket and the lower unitary machined bracket.

17. The carrier bearing assembly of claim 13, wherein the bracket comprises a machined aluminum bracket.

18. The carrier bearing assembly of claim 12, wherein a rubber bushing is configured to be disposed between the bracket and the frame of the UTV.

19. The carrier bearing assembly of claim 12, wherein the bracket comprises a machined aluminum bracket.
