ABSTRACT:
A motor driven or pedal powered snow vehicle designed to emulate the steering and balancing characteristics of motorcycles and bicycles. The snow vehicle includes a frame, a swing arm, a track carriage, an endless loop track, a snow compacting ramp, an elongated steering member and a ski. The swing arm pivots upon the frame and angles downward behind the frame. The track circulates a fixed path around the track carriage. The track carriage extends forward from a pivot connection with the rear of the swing arm, and pivots vertically under the swing arm in scissors-fashion. The snow vehicle is suspended upon the track carriage using a single shock absorber and load-distributing bell crank. A snow compacting ramp attached to the track carriage compresses the snow ahead of the track. The steering member is like the front suspension fork of a motorcycle or bicycle, and is connected to the frame so that it rotates about a steering axis. The ski is mounted to the lower portion of the steering member. An optional steering gyroscope is mounted or coupled to the steering member to provide gyroscopic stabilization to aid in balancing and steering the snow vehicle.
