20080196947 | Multi-pivot vehicle suspension - An all terrain vehicle and suspension providing frame members that pivot relative to each other and independent of supported track assemblies. Suspension frame sections pivot at supported bearings and torsion couplers. An endless track of each track assembly is trained around a framework having a drive sprocket and sets of idler wheels. The track assemblies independently pivot relative to the vehicle from a track suspension frame and supported sets of idler wheels mounted to torsion biased rocker arms that resist and bias the rocker arms and idler wheels to an equilibrium position and conformally shape the track to the terrain. Improved track drive lug surfaces are shaped to prevent track derailment. The vehicle frame and track assemblies independently rise, fall and pivot as obstacles of differing configurations and types are encountered to stabilize and maintain an operator body substantially parallel to the ground. | 08-21-2008 |
20090152037 | Motorized snowboard - A gasoline engine powered snowboard having an endless track trained about a support frame containing driven and idler wheels. Engine operation is directed from an upright operator support column. A molded chassis is hinge coupled to pivot about alternative contoured track support pan assemblies. The pan support assemblies cooperate with flexible track surfaces (e.g. fringe or pleat members) and foot supports to enable steering with foot and body movements. A lower support pan exhibits convex edge surfaces that contact track pleats or fringe pieces and includes an elliptic longitudinal channel. Alternative upper support pans provide a reciprocating wheeled steering plate, longitudinal drive lug channels and contoured snow diversion surfaces and/or an agitator. Internal track surfaces include UHMW pieces at or aligned to the drive lugs. Ground contact lugs exhibit traction promoting and snow clearing contoured profiles, shapes and recesses. | 06-18-2009 |
20090302676 | Track drive assembly - A track assembly having a drive sprocket capable of concentrically supporting several detachable drive rings containing drive teeth shaped to rotate without interfering with track support idler wheels, to provide a reduced center of gravity and substantially provide the same vehicle operating characteristic with tracks as with wheels. A track retainer guide member mounts along a peripheral edge of the track and overlies the track to resist track dislodgement. Independent and/or resiliently biased, rocker arms support track idler wheels to induce track flexion and conformance to encountered obstructions. | 12-10-2009 |
