ABSTRACT:
A stabilizer unit having a pair of mounting rods adapted to extend fore and aft of a vehicle frame and to be pivoted at front ends thereof to locations near the outer ends of the rear axle of the vehicle. The rear ends of the mounting rods are adapted to be shiftably coupled by coil springs to respective bolts secured to and extending downwardly from respective frame members of the vehicle. A cross rod interconnects the rear ends of the mounting rods and acts as a sway bar. A pair of inflatable air springs or shock absorbers are disposed between respective frame members and the mounting rods, the air springs being between the front and rear ends of the mounting rods. When the stabilizer unit is to be put in use when a load is carried by the vehicle, the cross rod is secured against movement relative to the vehicle frame members by a pair of spaced, notched crank arms on a rotatable clamp rod carried by the vehicle, the notches of the crank arms receiving the cross rod as the clamp rod is rotated relative to the vehicle into an operative position. Inflation of the air springs then causes downward pressure on the mounting rods and thereby the rear axle to thereby cause a slight elevation of the rear end of the vehicle without any significant change in the elevation of the front end of the vehicle to thereby provide for uniform up and down movement of the frame when the wheels move over bumps in the roadway.
