STEERING SKIS FOR SNOWMOBILES AND SIMILAR VEHICLES

摘要

Steering skis for snowmobiles and similar vehicles. The ski has a lower surface for contacting the snow and at least one upwardly curved lateral edge in a region of the ski used for support of the vehicle. The curved lateral edge defines a convex curved snow-engaging surface which merges smoothly with the lower surface of the ski. The curved edge generates lift during turning of the ski while minimizing drag characteristics of the ski. The ski is less likely to result in tipping during turns at high speed in deep snow, which improves the safety of the vehicle. The curved edge produces minimal drag while turning and this allows for more use of the lift generated by the ski.
