摘要：An air-ride axle/suspension system for a wheeled vehicle is provided. The system includes a pair of pivot bushings for pivotally mounting the system to a frame of the vehicle, pairs of shock absorbers and air springs, and a pair of axle spindle ends for mounting wheels on the system. The improvement includes an integral non-hollow structure, including a pair of arms and a cross member. The pair of arms is transversely spaced relative to the vehicle, with each of the arms extending in a longitudinal direction relative to the vehicle. Each arm includes an upper surface, a lower surface, and an inboard surface extending vertically between the upper and lower surfaces. The cross member extends transversely between the arms and is connected to each one of the arms. The cross member includes a vertically disposed portion and a horizontally disposed portion, with the horizontally disposed portion being connected to the inboard surface of each of the arms between the arm upper and lower surfaces. The pivot bushings, shock absorbers, air springs, and axle spindle ends are mounted on the integral structure, whereby roll forces encountered by the axle/suspension system during vehicle operation are distributed throughout the integral structure to enable the system to achieve roll compliance.
