Abstract:
An anti-roll suspension system for a vehicle chassis having at least two laterally spaced front wheels and two laterally spaced rear wheels, the suspension comprising:an axle assembly for mounting each of a pair of laterally spaced front wheels; an axle assembly for mounting each of a pair of laterally spaced rear wheels; a spring assembly comprising a spring for mounting the chassis on each of the axle assemblies; a moveable arm connected between each spring assembly and the chassis; and an anti roll linkage connected to said chassis and to said moveable arm, said anti roll linkage comprising a bell crank for pivotal mounting to a vehicle chassis having one arm connected to an axle assembly and a compensating link connecting another arm to said moveable arm for receiving and translating said lateral movement to said moveable arm, such that said anti roll linkage translates a lateral movement of the chassis to a vertical downward movement of said moveable arm to the spring on a down force side of the chassis and a vertical upward movement of said moveable arm to the spring on an up force side of the chassis so that the anti roll linkage simultaneously lifts the down force side of the chassis and lowers the up force side of the chassis.
