ABSTRACT:
A half-track all-terrain vehicle having an independent suspension system that provides an improved vehicle ride and facilitates traversing obstacles. The vehicle includes a frame, a pair of beams that each holds front and rear wheels, and a suspension system extending between the each beam and the frame. The suspension system includes a plurality of cushions. The cushions are tuned such that forward cushions have a relatively greater suspension stroke than the rearward cushions and thereby permit the front wheels to engage the ground sequentially before the rear wheels when the vehicle goes over a step or drop off. The suspension system is further tuned to permit the vehicle to traverse an obstacle having a height that is slightly lower than the frame clearance by permitting the front wheels to lift vertically to a distance essentially equal to the frame clearance.
