Abstract

A Powersports vehicle is disclosed which includes a frame, ground engaging members supporting the frame, comprising at least two front wheel, and a power source for driving the front wheels. A front drive is coupled to the power source and to the front wheels, the front drive being coupled to the frame through isolation mounts to reduce vibration of the front drive through the frame.

First claim

What is claimed is:

1. A utility vehicle, comprising:
a plurality of wheels;
a frame supported by the plurality of wheels, the frame comprising a front frame portion;
a powertrain supported by the frame;
a drive member supported by the front frame portion and a prop shaft extending between the powertrain and the drive member, the drive member comprising:
a drive housing comprising a drive input and a drive output;
a plurality of collars extending substantially perpendicular to a longitudinal centerline of the vehicle, the plurality of collars including a first collar and a second collar and at least one of the plurality of collars extending laterally outward of the drive output, the first collar and the second collar are positioned about the center of the drive output such that the first collar is forward of the center of the drive output and the second collar is rearward of the center of the drive output, and wherein a first axis is defined between the center of the drive output and the first collar and a second axis is defined between the center of the drive output and the second collar; and
an angle between the first axis and the second axis is in a range of a first value and a second value, the first value being less than the second value, and the second value being 170 degrees.

2. The utility vehicle of claim 1 , further comprising an isolation member positioned within each of the first collar and the second collar.

3. The utility vehicle of claim 2 , wherein the isolation member further comprises a first portion and a second portion, the first portion having a hardness greater than a hardness of the second portion.

4. The utility vehicle of claim 3 , wherein the second portion includes a pair of isolation grommets and the first portion includes a sleeve extending between the pair of isolation grommets.

5. The utility vehicle of claim 4 , wherein the isolation grommets have a diameter greater than the diameter of the sleeve.

6. The utility vehicle of claim 1 , wherein the drive member is coupled to the front frame portion through the first and second collar.

7. The utility vehicle of claim 6 , further comprising a steering assembly wherein a portion of the steering assembly is supported by the front frame portion.

8. A utility vehicle, comprising:
a plurality of wheels;
a frame supported by the plurality of wheels, the frame comprising a front frame portion;
a powertrain supported by the frame;
a drive member supported by the front frame portion and a prop shaft extending between the powertrain and the drive member, the drive member comprising:
a drive housing comprising a drive input and a drive output;
a first collar and a second collar extending substantially parallel to the drive output, each collar configured to house an isolation member and a fastener, a vertical plane and a horizontal plane each containing the drive output define four quadrants, the first collar positioned at the top of the drive housing in a first quadrant of the four quadrants and the second collar is positioned in a second quadrant of the four quadrants;

a first axis is defined between the center of the drive output and the first collar and a second axis is defined between the center of the drive output and the second collar; and
an angle between the first axis and the second axis is in a range of a first value and a second value, the first value being less than the second value, and the second value is 170 degrees.

9. The utility vehicle of claim 8 , wherein at least one of the first collar and the second collar extends laterally outward of a lateral extent of the drive output, and the drive member is coupled to the front frame portion at the first collar and the second collar.

10. The utility vehicle of claim 9 , further comprising an isolation member positioned within each of the first collar and the second collar.

11. The utility vehicle of claim 8 , wherein the first collar and the second collar comprise an isolation member, and the isolation member includes a first portion and a second portion wherein the first portion has a hardness greater than the second portion.

12. The utility vehicle of claim 11 , wherein the second portion includes a first isolation grommet with a first inner axial end face and a second isolation grommet with a second inner axial end face, and the first portion includes a sleeve extending directly between the first inner axial end face and the second inner axial end face.

13. The utility vehicle of claim 8 , wherein the drive member extends lower than the front frame portion.

14. The utility vehicle of claim 13 , wherein the second collar is positioned lower than the drive input.

15. The utility vehicle of claim 8 , wherein the front frame portion is removable from the frame.

16. The utility vehicle of claim 15 , further comprising a steering assembly, wherein a portion of the steering assembly is coupled to the front frame portion.
