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 powertrain mount assembly for a vehicle, the mount assembly comprising:
a frame including a plurality of three-sided channels each having a first side wall, a second side wall, and a third wall connecting the first side wall and the second side wall to form a U-shaped configuration having a space between the first side wall and the second side wall;
a powertrain component positioned between two of the plurality of three-sided channels, the powertrain component being a front drive having an input and an output, the input being adapted to be coupled to a prop shaft and the output adapted to drive at least one wheel of the vehicle,
the powertrain component being removably coupled to a first three-sided channel of the plurality of three sided channels with a removable fastener at a first vertical location, the removable fastener extending into the space of the first three-sided channel of the plurality of three-sided channels between the first side wall of the first three-sided channel of the plurality of three-sided channels and the second side wall of the first three-sided channel of the plurality of three-sided channels,
the plurality of three-sided channels including a first aperture to couple a first suspension arm at a second vertical location vertically offset from the first vertical location;
the plurality of three-sided channels including a second aperture to couple a second suspension arm at a third vertical location vertically offset from the first vertical location and from the second vertical location,
the first vertical location being laterally closer to a centerline of the vehicle than both the first second vertical location and the third vertical location.

2. The powertrain mount assembly of claim 1 , wherein the first and second apertures are defined through the plurality of three-sided channels in a longitudinal direction of the vehicle.

3. The powertrain mount assembly of claim 1 , wherein the first aperture is defined through the first side wall and second side wall of one of the plurality of three-sided channels.

4. The powertrain mount assembly of claim 1 , wherein the second aperture is defined through the first side wall and second side wall of one of the plurality of three-sided channels.

5. The powertrain mount assembly of claim 1 , wherein the removable fastener extends in a lateral direction of the vehicle.

6. The powertrain mount assembly of claim 1 , wherein the removable fastener includes a bolt head that is positioned adjacent to and accessible from one of the first and second side walls of the plurality of three-sided channels.

7. The powertrain mount assembly of claim 1 , wherein the plurality of three-sided channels include recesses configured to receive frame members.

8. The powertrain mount assembly of claim 1 , wherein the powertrain component includes a differential.

9. The powertrain mount assembly of claim 1 , wherein powertrain component includes a collar through which the removable fastener extends.

10. The powertrain mount assembly of claim 1 , further comprising a front drive mount operable to couple to a vehicle frame.

11. The powertrain mount assembly of claim 10 , wherein the front drive mount is operable to be coupled to the vehicle frame such that the powertrain mount assembly is positioned at least partially vertically between an upper frame member and a lower frame member of the vehicle frame.

12. The powertrain mount assembly of claim 1 , wherein an opening is defined by the plurality of three-sided channels.

13. The powertrain mount assembly of claim 12 , wherein the opening provides access to the powertrain component.

14. The powertrain mount assembly of claim 12 , wherein one of the plurality of three-sided channels is coupled to a post.

15. The powertrain mount assembly of claim 14 , wherein the post defines a boundary of the opening.

16. The powertrain mount assembly of claim 1 , wherein the first suspension arm is coupled to a second three-sided channel of the plurality of three-sided channels, the second three-sided channel being spaced apart from the first three-sided channel.
