Abstract
An improvement is provided for a vehicle suspension of the type comprising a pair of control arms pivotally mounted to a frame of the vehicle and carrying ground-engaging wheels. A transverse beam extends between the free ends of the control arms and supports a pair of air springs. A carriage is also pivotally connected to the frame which is mounted to an upper portion of the air springs so that the air springs are disposed between the carriage and the transverse beam. The carriage includes a brace for bracing the carriage relative to the frame when the wheels are in a highway mode. During retraction of the wheels from engagement with the ground surface, the brace is released from engagement with the frame during a first stage of retraction, and the control arms and carriage are moved toward the frame during a second stage of retraction.
