ABSTRACT:
An air lift axle assembly (2) for stabilizing a vehicle (1) which is subjected to crosswinds. The assembly also increases the vehicle's ultimate load carrying capacity. The assembly includes a set of tires (3) which may be remotely lowered to engage the road surface (4) by means of an inflatable bladder (28) which presses against a spar (22), the spar being pivotably mounted to the vehicle by means of hollow bar (10). Springs (25) retract the assembly when not in use such that the deflated bladder (28) is housed within a canister (27), the canister (27) providing sufficient support to the inflated bladder (28) such that additional longitudinal stiffening of the bladder (28) is unnecessary.
