Abstract: A snow vehicle basically includes a vehicle body, a saddle seat, at least one ski, an engine, a starter motor and a lithium power module. The engine is attached to the vehicle body. The starter motor is operatively coupled to the engine and electrically coupled to a first electrical connection. The lithium power module has a lithium battery with a second electrical connection that is configured to be toollessly connected and disconnected to the first electrical connection.

Abstract: Disclosed is an improved snowmobile ski suspension including a pair of airspring biasing mechanisms whose air volumes are interconnected by a cross linking conduit that incorporates an open and closed switch. In an alternative embodiment a simpler configuration is provided for which does not include the use of an open or closed switch manifold.

Abstract: A simple and cost effective air sprung suspension for tracked vehicles. The apparatus having at least one suspension arm, a track guiding means that include a pair of slide rails, a set of carrier wheels and a set of rear wheels. An air spring biasing mechanism and a shock absorber are mounted along side each other and within the space between the two slide rails. The new mounting arrangement provides for both a simple and cost effective technique of obtaining individual rates of displacement for the shock and air spring. The separately optimized rates of displacements cause the air spring and shock absorber to operate more effectively as a system in delivering greater comfort and increased separation for the occupants from the often rough and varied terrain a tracked vehicle encounters.

Abstract: A snowmobile construction comprising a body frame and having slide rails suspended from the body frame through a front and rear suspension arm, and an endless track which runs under tension upon a drive and a plurality of driven wheels rotatably borne on the slide rails. The rear suspension has front and rear suspension arms which connect the body frame and the slide rails in parallelogram linkage fashion. Compression coil springs and shock absorbers are operatively mounted between the slide rails and the front and rear suspension arms. An inclined slide block and slot coupling interconnects the rear suspension arm and each slide rail to automatically react both front and rear suspension arms upon initial encounter of the slide rails with a snow bump at either end of the slide rail. This coupling also urges the snowmobile into an upwardly pitched condition upon acceleration with the forward ends of the slide rails digging into the ground surface for enhanced traction.
