Abstract: An anti-sway system for a steerable vehicle of the type employing a torsion bar suspension system. Operatively coupled to the torsion bar for each of the vehicle's steerable wheels or skis is a mechanism for increasing the effective spring rate of the suspension upon cornering over that prevailing when steering a straight line course.

Abstract: A three-wheeled motor vehicle having a two-part frame construction in which a front frame member includes the front steerable wheel assembly and the supports for the driver's seat, and the rear frame assembly includes support for the engine and a driven pair of rear wheels. The front and rear frames are pivotally joined to allow rotational motion of the front frame assembly relative to the rear frame assembly about a generally longitudinal axis, and an arcuate guide bar and associated slide bearings are used to couple the rearmost seat supports of the front frame to the rear frame providing desired rigidity to the composite frame structure.

Abstract: An anti-roll and self-centering torsion bar arrangement for the front suspension of a snowmobile. A torsion bar is interconnected between the strut suspensions of the front skis so as to be loaded during cornering and prevent roll. In addition the point of connection between the torsion bar ends and the skis is such that a self-centering force is generated during steering movements. The torsion bar and its connection to the suspension is disposed so that the suspension and forwardmost portion of the body will be protected from damage when obstructions are encountered.

Abstract: In a steering ski, for a snowmobile, of the type having an elongated body continuous with an upturned forward tip, the improvement which comprises flares extending along the body and upturned at angles in the range between 30.degree. and 60.degree., the flares continuing around the forward tip in a downwardly concave arcuate lip configuration.

Abstract: An improved suspension system for the drive track of a snowmobile that offers wide amounts of suspension travel and yet is compact enough to be positioned internally of the track. The suspension system permits the use of a tubular shock absorber and a surrounding coil spring for both the front and rear portions of the track. Both front and rear suspension systems embody a link arrangement for moving the ends of the shock absorber and spring toward each other upon upward travel of the track relative to the snowmobile body so as to achieve a wider range of damping for a given degree of suspension travel.

Abstract: A suspension arrangement for the steering skis of a snowmobile that permits soft ride through high suspension travels while at the same time prevents roll during cornering. The suspension system includes an element that is moveable with each of the skis during its suspension travel but which does not rotate with the ski during steering. Each of these respective elements is coupled to a torsion bar for loading the torsion bar upon relative vertical movement between the skis so as to resist body roll.
