Abstract
A snow vehicle is disclosed comprising a vehicle frame, a propulsion unit coupled to the frame, and a front ski steered by a steering mechanism. The front of the vehicle includes a first front suspension and a second front suspension coupled to the ski. The rear suspension includes a bumper assembly preventing bottoming out of the rear suspension. The rear suspension is coupled to the vehicle frame such that the longitudinal spacing between the vehicle frame and rear suspension is adjustably controllable.
Claims21
A snow vehicle comprising:
- a vehicle frame;
- a propulsion unit coupled to the frame;
- at least one front ski;
- a steering mechanism coupled to the frame;
- a first front suspension coupled to the frame;
- a second front suspension coupled to the at least one ski;
- a rear suspension coupled to the frame, the rear suspension comprising:

A rear suspension for a snow vehicle comprising:
- at least one slide rail;
- a frame;
- at least one control arm coupled between the slide rail and the frame;
- at least linear force element coupled between the slide rail and the frame;
- at least one carrier roller coupled to one of the slide rail and the frame;
