    摘要： A method and system are set forth for determining the force necessary to separate a first and a second mass by using an inflatable member such as an air spring. More specifically, the invention includes a system and method for load leveling of a vehicle. The system and method includes means for determining the weight on each spring by inflating the spring at a substantially constant rate. The pressure of the gas within the air spring is sensed at time intervals and, through a microprocessor or the like, the sensed pressure at the time intervals is assembled into a pressure-time history. From the pressure time history, the pressure is determined at which the chassis begins to lift. The determined pressure is processed to give an indication of the weight of the chassis borne by the air spring. The foregoing procedure is repeated for each air spring so that a gross vehicle weight can be determined as well as the distribution of weight upon each air spring. Once weight borne by each spring is known, the control can supply the correct pressure to the air spring to support such weight at the desird height.

    摘要： A method and system are set forth for leveling a vehicle chassis supported on air springs. The system and method include a position switch at each air spring which is adapted to generate a signal when the spring is compressed to or beyond a desired length representing the desired level for the vehicle chassis. Based upon the duration of the signal over a time interval a duty cycle for the spring is established. If the duty cycle is below a desired valve or range of valves this indicates the chassis is too high and the system incrementally deflates the spring. If the duty cycle is above the desired valve or range of valves this indicates the chassis is too low and the spring is incremetally deflated. Accordingly, leveling can take place when the vehicle is in motion.

    摘要： An embodiment of the present invention is a valve for selectively establishing communication of a fluid between first and second fluid bodies having first and second pressures, respectively. A valve element is carried within a valve body for linear reciprocal movement along a valve axis between a first position wherein an operative portion at the front of the valve element blocks communication between the first and the second fluid bodies and a second position wherein the first and second fluid bodies are in communication. The movement is responsive to a rearward force exerted by the fluid on the valve element due to the first pressure. The rearward force is less than the product of the first pressure and a cross-sectional area of the first fluid swept by the valve element. An actuator is located at or behind the valve element for applying and modulating forward force to the valve element for controlling the response of the valve element to the first pressure when the valve is located between the first and second positions.

    摘要： A vehicle suspension system in which a computer controls damping and spring forces to optimize ride and handling characteristics under a wide range of driving conditions. A combined shock absorber/air spring unit is connected between the wheel and frame of a vehicle. The shock absorber includes a hydraulic sensor which provides signals to the computer which are representative of the position of the piston within the shock absorber. The computer utilizes these signals to control compression and rebound hydraulic pressure regulators to produce preprogrammed compression and rebound damping forces that will yield the desired ride and handling. The air spring may be connected in series with the shock absorber for compression and rebound along the same axis. Pressure sensors and air pressure inlet and outlet valves are connected to the computer for adjusting the pressure within the air spring to provide the desired spring rate.
