A snow vehicle suspension system including a pair of suspension struts associated one with each of the two steerable skis of the vehicle; each of the struts including a first generally tubular shaped housing fixably secured to the underside of the vehicle above the associated of the skis, a second generally tubular housing telescopically disposed within the first housing and connected at the lower end thereof to the associated ski, shock absorbing means within the second housing and including a reciprocable piston mounted on one end of a piston rod extending axially outwardly from the upper end of the first housing, the upper end of the piston rod being secured to a portion of the vehicle above the strut and having a helical coil spring extending coaxially thereof between the upper end of the strut and the aforesaid vehicle portion, a steering arm having a first portion operatively connected to the vehicle steering mechanism and a second portion rotatable about the longitudinal axis of the strut, with a second portion of the steering arm being slidably and non-rotatably connected to the second housing whereby the second housing is movable longitudinally thereof relative to the arm and is rotatable in response to actuation of the steering mechanism concomitantly with the arm.

A suspension strut for a snow vehicle having at least one steerable ski, said strut comprising first and second telescopically slidable housings, one of said housings being fixedly secured to an associated portion of the vehicle, means on one of said housings for securing said strut directly to the steerable ski, shock absorbing means within one of said housings and including a damping piston cooperable with a quantity of damping fluid, and a piston rod extending axially from one end of said strut, said shock absorbing means being operable to dampen relative telescopic movement between said first and second housings, a helical coil spring means arranged coaxially of said strut, said spring means comprising the main suspension spring for said ski and yieldably resisting movement of said ski toward the vehicle, and a steering element for rotating said ski relative to the vehicle upon actuation of an associated vehicle steering mechanism, said steering element being connected to one of said housing members and being rotatable therewith about an axis extending generally coaxially of said strut when a steering force is applied to said element by said associated vehicle steering mechanism.
