Abstract
A vehicle suspension system having a pair of hanger brackets, with one control arm and one torque arm pivotally mounted on one end to each hanger bracket. Each control arm and each torque arm is pivotally attached to one of a pair of axle seats at another end. One end of a stabilizer bar is mounted to a control arm to increase the suspensions roll stability, and resistance to lateral deflection. The pivotal connections on either end of the control arm include a flexible bushing formed with a hole, and a pivot pin extending through the hole. A lift mechanism includes a compression spring acting against a force plate to move a pair of tire-wheel assemblies between ground engaging and non-ground engaging positions through an interconnected lift bar. The lift mechanism will raise the tire-wheel assembly between a non-ground engaging position, a first ground engaging position, and a second ground engaging position for use in roadrailer applications.
