Abstract

A retractable suspension (10) comprises a trailing arm (22) pivotally mounted to a vehicle frame (12), an air spring (30) mounted between the trailing arm and the frame, and a lifting device (32) mounted between the trailing arm and the frame. The lifting device (32) comprises a strut (60) pivotally mounted between the frame (12) and a lever arm (64) that is fixedly mounted to the trailing arm (22). The strut (60) applies a force to the lever arm (64) that imparts a moment to the trailing arm (22) to urge the trailing arm and attached wheels (14) to a retracted position. The force of the air spring (30) can be adjusted to counter the upward movement of the wheels (14).
