Abstract
A trailer suspension comprises a pair of beams mounting a pair of axles and fluidly interconnected air springs. During normal forward travel, when one axle traverses a bump, the air springs have a low spring rate. During cornering, the spring rate is much higher to provide roll resistance. Bumpers limit the roll on an outboard side of the trailer. A flexible connector between the beam and frame further limits roll on an inboard side of the trailer. The beam is pivotally mounted to a vehicle frame rail through a relatively long radius rod thereby reducing creep to a negligible amount.
