ABSTRACT:
A suspension system for a vehicle equipped with a pair of belts arranged on opposite lateral sides of the vehicle's frame wherein each belt is entrained about an elevated drive wheel, a front and a rear idler wheel, and roller wheels arranged longitudinally between the idler wheels. Resilient front, intermediate, and rear struts connected respectively between the frame and a support apparatus of which the front idler comprises a portion, between the frame and one set of roller wheels, and between the frame and the rear idler wheel provide the vertical support for the vehicle's frame. Fluid interconnection of the front struts provides lateral load sharing during low speed vehicle operation and, during high speed vehicle operation, fluid interconnection of each front strut with its own accumulator provides independent suspension. Selective fluid interconnection of the rear strut with a recoil strut which provides the desired belt tension maintains belt to wheel engagement for high speed vehicular operation. Selective fluid isolation of the rear strut and a pry-out strut connected between the recoil strut and a pivoting beam on which the front idler is mounted enables application of the maximum vertical forces on vehicle attached implements.
