<p>A suspension system (18) for a vehicle (10) equipped with a pair of belts (117) arranged on opposite lateral sides of the vehicle's frame (14) wherein each belt (117) is entrained about an elevated drive wheel (24), a front (64) and a rear idler wheel (42), and roller wheels (50, 90) arranged longitudinally between the idler wheels (42, 64). Resilient front (38), intermediate (36), and rear (34) struts connected respectively between the frame (14) and a support apparatus (28) of which the front idler (64) comprises a portion, between the frame (14) and one set of roller wheels (50), and between the frame (14) and the rear idler wheel (42) provide the vertical support for the vehicle's frame (14). Fluid interconnection of the front struts (38) provides lateral load sharing during low speed vehicle operation and, during high speed vehicle operation, fluid interconnection of each front strut (38) with its own accumulator (122) provides independent suspension. Selective fluid interconnection of the rear strut (34) whith a recoil strut (70) which provides the desired belt tension maintains belt (117) to wheel engagement for high speed vehicular operation. Selective fluid isolation of the rear strut (34) and a pry-out strut (100) connected between the recoil strut (70) and a pivoting beam (68) on which the front idler (64) is mounted enables application of the maximum vertical forces on vehicle attached implements (136).</p> |
