Abstract
An adaptive vehicle suspension assembly includes a transverse leaf spring mounted in series with pneumatic springs at the front and rear wheels of a motor vehicle. A control circuit includes inlet and exhaust solenoid valves to control the flow of pressurized air into or out of the pneumatic springs, providing variable spring rate and vehicle height. Vehicle sensor switch provides control of the operation of the solenoid valves in response to sensed vehicle height increasing or decreasing the spring rate and providing optimum vehicle ride, load and cornering control.
