ABSTRACT:
A strut-type suspension for the steering ski of a snowmobile. The suspension includes a fixed tube attached to the chassis, and a movable tube axially movable in the fixed tube. A bias spring is mounted in compression between the movable tube and a spring seat attached to structure fixed to the chassis, which spring seat overhangs the movable tube. A shaft supporting a piston fitted in a cylinder inside the movable tube is linked to the spring seat by alignment means which permit shear-like relative movement between the shaft and the fixed tube.
