<p>A suspension system (12) for a non-powered belted vehicle (10) includes a pair of wheel assemblies (16, 18, 22, 24) positioned on each side of the vehicle (10), a flexible endless belt (28, 30) encircling each pair of wheel assemblies (16, 18, 22, 24), and an axle assembly (32) extending transverse to the wheel assemblies (16, 18, 22, 24). The wheel assemblies (16, 18, 22, 24) are connected to the axle assembly (32) by a plurality of pivotal arms (34, 36, 38, 40) and each pair of wheel assemblies (16, 18, 22, 24) are interconnected by a fluid actuated cylinder (68). Belted vehicles which utilize smooth wheels to frictionally engage the belt for driving and stopping the belt, require considerable tension between the wheels and the belt. High belt tension is desirable for driving and stopping but unnecessarily high belt tension is undesirable due to overstressing of vehicle components. The subject suspension system (12) utilizes a variable load applied to the vehicle (10) to increase the belt tension for efficient vehicle operation.</p> |
