Title: Snowmobile suspension system

Abstract: To enable a rider to control in real time the type of ride he desires, a snowmobile is equipped with a suspension system that includes at least one fluid actuated device which can be adjusted in real time to control the relative distance between the body of the snowmobile onto which the rider sits and the frame, or the slide tracks about which the drive belt is mounted. By setting a constant predetermined desirable distance between the body and the slide tracks, or the frame, of the snowmobile, an optimal cushioned ride for the rider is obtained. The control of the fluid actuated device(s) may be effected at any time manually by the rider, or be effected by a feedback system. The snowmobile is also equipped with an ABS system for enhancing the traction of the drive belt on snow and therefore the control of the snowmobile by the rider.
