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.

Abstract: A crawler vehicle comprises a body frame and an auger mounted to the body frame at a front portion thereof, the body frame being mounted to a rear portion of a crawler frame via a pivot shaft to allow the crawler frame carrying a crawler belt to swing vertically. The pivot shaft is located forwardly of a lower idle wheel rotatably mounted to the crawler frame. Positioning of the pivot shaft forwardly of the lower idle wheel allows the auger to move downward even when a front portion of the crawler belt is lifted. This causes the auger to move downward regardless of new snow or hard snow, enabling the auger to carry out snow-removing operation in a highly efficient manner.

Abstract: A crawler-belt vehicle is a half crawler vehicle having front wheels furnished with tires, and crawlers on a rear wheel side composed of crawler belts extending between intermediate wheels and rear wheels. The front wheels are larger in diameter than the intermediate wheels and the rear wheels and, hence, have a large ground-contact surface area. Thus, while the vehicle is running on snow, the front wheels are not apt to sink in the snow to a greater extent with the result that the turning characteristic and breakthrough characteristic of the vehicle can be improved. The intermediate wheels may be set to toe in so as to prevent detachment of the crawler belts which would otherwise occur when the sub-beams are slightly flexed or deformed in a lateral outward direction under loads applied thereto while the vehicle is traveling at high speeds on the snow.
