ABSTRACT:
A vehicle energy absorbing system for a vehicle having a suspension system, a frame and an axle, wherein the frame is spaced apart from the axle in a vertical direction and the suspension system mechanically couples the frame to the axle. The system includes an expandable air bag mechanically coupled to the frame and to the axle, a distance indicator for indicating a vertical distance between the frame and the axle attached to the vehicle, an air bag pressure control valve fluidly connected to the air bag and coupled to the distance indicator, and a source of air under pressure attached to the vehicle and fluidly coupled to the air bag pressure control valve through a control panel. When the indicator indicates a first distance between the frame and the axle, the valve is positioned in a first position supplying air from the source of air to the air bag at a first air pressure, and when the indicator indicates a second distance between the frame and the axle, the valve is positioned in a second position supplying air from the source of air to the air bag at a second air pressure.
