ABSTRACT:
A slide rail structure for a snow vehicle includes a main slide rail disposed at the middle of a crawler belt with respect to the width of the crawler belt. A pair of side slide rails are disposed near the opposite side ends, respectively, of the crawler belt. The guide wheels are disposed between the main slide rail and the side slide rails. An appropriate contact load is maintained between the snow vehicle and the snow to thereby enhance the turning ability of the snow vehicle. One or more edges can be provided on a lower surface of the body cover of the snow vehicle. These edges can dig into the snow to compensate for a reduction in the contact force of the affront ski of the snow vehicle with the snow during turning. The front ski of the snow vehicle can be mounted using an elastic, biasing member. This member helps improve timing and responsiveness for turning of the snow vehicle.
