ABSTRACT:
A front suspension and stabilizing system for a snowmobile in which a pair of front steerable skis are connected to the vehicle body through a pair of suspension means which also are connected to a transversely extending torsion member attached to the vehicle body. The response of the torsion member to movement of the suspension means is stabilized and dampened by a resilient yieldable means such as a shock absorber connected to a mid portion of the torsion member through a forwardly extending arm fixed to the torsion member and connected at its other end to the shock absorber. A stabilizing system for a suspension system having a steering strut subject to axial and rotational movement, the steering strut being connected to a torsion member through a forwardly disposed link having universal connections to the strut and to the torsion member. The longitudinal axis of the link lies in a vertical plane which passes through the axis of the steerable strut and the longitudinal axis of the ski for transmitting vertical movement of the ski and associated steering strut to the torsion member during travel in a straight direction as well as during turning of the vehicle.
