ABSTRACT:
A suspension system for use in a motor vehicle that is self-adjusting in response to vehicle load and roadway conditions. The system incorporates a pneumatic arrangement for such an adaptive load dependent system which connects air springs with fluid-cushion shock absorbers. The pneumatic arrangement may directly connect the air springs and the shock absorbers to a high pressure circuit that provides a firm ride to the vehicle. Alternatively, the system may be switched to indirectly connect the air springs and the shock absorbers to a low pressure circuit that provides a soft ride. A sensor is provided to sense conditions that operate a control valve to switch between the firm ride and the soft ride choices.
