ABSTRACT:
A ski edging device for a snowmobile includes an articulable joint connected between the snowmobile body and the skis to permit rotation of the skis relative to the body about a steering axis and to permit rotation of the skis relative to the body about a camber axis to control the angle of the inclination of the skis during turning maneuvers to prevent lateral side slipping of the snowmobile. A first control arm is secured to a portion of the articulable joint to move with rotation of the skis about the steering axis and a second control arm is secured to a second portion of the articulable joint to move with rotation of the skis about the camber axis. A cable and pulley system is connected between the first and second control arms such that a turning movement of the skis about the steering axis causes the first control arm to vary the position of the second control arm to rotate the skis about the camber axis to provide the desired edging effect. The device provides for a change in the angle of inclination of the skis relative to the snowmobile body in proportion to the turning radius of the skis to provide an edging effect that limits lateral side slippage to permit higher safe-turning speeds.
