Abstract
A snowmobile ski suspension comprises a telescopic strut formed from a fixed support tube and a guard tube reciprocably and swivelly mounted in the guard tube. The support tube is fixed to one end of a crossbar of the snowmobile frame. Steering of a ski attached to the bottom of the guard tube is accomplished by rotating a bifurcated steering arm, which is journaled on the support tube so as to straddle the crossbar, the steering motion being transferred to the ski by a hinge connected between the steering arm and the ski. A shock absorber and a coil compression spring are mounted in the strut and act to resist collapse of the latter.
