Abstract:
A self-adjusting, self-damping air spring having a first air spring disposed between a cab and a frame of a vehicle and a second air spring in fluid communication with the first air spring. The second air spring positioned relative to the first to provide an opposition force in response to a change in height of the first air spring. This change in height corresponds to a change in displacement between the cab and the frame. The opposition force provided by the second air spring acting to dampen the changes in displacement.
