SNOWMOBILE SUSPENSION SPRING ADJUSTMENT

A snowmobile includes a pair of longitudinally-spaced suspension links which pivotally connect a slide bar or rail member to the main frame of the snowmobile for vertical and fore-and-aft movement relative to the frame. Torsion spring members, which in one embodiment comprise helically wound wires and which in a second embodiment comprise torsionally deflected elastomeric members, act between the links and adjustment, the latter being arms vertically adjustably pivoted to the main frame. The connections of the spring elements to the links and the arms are such that the biasing force exerted on the links is increased by swinging the arms downwardly and is decreased by swinging the arms upwardly.
