Abstract
A wheel suspension system is disclosed which includes a wheel support member pivotally mounted to a vehicle frame, a wheel rotatably mounted to the support member on a stub axle, and an airbag positioned between the wheel support member and the vehicle frame to bias the support member into an intermediate position between a lowermost position and an uppermost position, the rotational axis of the wheel being positioned at or above the cargo floor of the vehicle at least when the wheel support member is in the uppermost position. The suspension system provides a compact lateral profile and also aligns the pivot axis and biasing airbag on a common side of the wheel to provide a compact profile along the length of the vehicle. The compact lateral profile of the suspension system is enhanced by a lateral stabilizer configuration that includes a leaf spring extending parallel to the longitudinal axis of the vehicle directly adjacent the suspension system, thus providing maximum distance between the wheels and permitting the cargo floor to be supported between the wheels below the rotational axis of the wheels.
