ABSTRACT:
An auxiliary lift axle wheel assembly is mounted to a vehicle body by L-shaped levers, each of which is pivotally mounted at the intersection of its legs to the vehicle, and the lift axle is held in its upward, unloaded position on the longitudinally extending legs of the levers by the force of springs bearing against the upwardly extending legs of the levers. Air inflatable air springs positioned between the auxiliary lift axle and vehicle body are filled with air to move the auxiliary axle downward relative to the vehicle body with force sufficient to overcome the force of the springs to urge the wheels of the axle down into load-bearing engagement with the road surface beneath the vehicle.
