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.
Claims58
A vehicle, comprising:
- a frame;
- ground engaging members supporting the frame, comprising at least two wheels;
- a power source;
- a drive coupled to the power source at a drive input and coupled to one of the at least two wheels at a first drive output on a first side of the drive and to the other of the at least two wheels at a second drive output on a second side of the drive, the drive being coupled to the frame through at least one isolation mount to reduce vibration of the drive through the frame;
- wherein a lateral outermost edge of the isolation mount extends beyond a lateral outermost edge of the drive output on at least one side of the drive and at least a portion of the isolation mount is supported by the drive.

A vehicle, comprising:
- a frame;
- ground engaging members supporting the frame, comprising at least two wheels;
- a power source;
- a drive coupled to the power source at a drive input and to the wheels at a drive output on each side of the drive, wherein the drive includes a housing having a first collar mounted adjacent to a top of the housing, and a second collar extending substantially perpendicular to a longitudinal centerline of the vehicle, and includes resilient isolation grommets positioned in each end of the second collar the drive being coupled to the frame through at least isolation mounts to reduce vibration of the drive through the frame, wherein the isolation mounts comprise resilient isolation grommets which are inserted into the collars and wherein a lateral outermost edge of the isolation mount extends beyond a lateral outermost edge of the drive output on at least one side of the drive, and wherein extreme lateral positions of the second collar extend beyond a lateral width position of the drive housing and wherein isolation mounts are positioned in the second collar and extend to at least an end of the second collar at each end.
