ABSTRACT:
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.
