Abstract: A shock absorber, in which external gas is sucked by movement of a piston rod to obtain compressed gas, which is used for inhibiting the “lag” phenomenon. A piston valve is connected to one end of a piston rod received in an inner shell and moved between rebound and compression strokes, an inner space of the inner shell being divided into a rebound chamber and a compression chamber by the piston valve. A reservoir chamber is provided in an outer shell outside of the inner shell to supply oil to the compression chamber in the rebound stroke and to recover oil in the compression stroke. The shock absorber has a high pressure tank with a high pressure chamber installed outside of the outer shell, and a self pumping unit for sucking gas and pumping it into the high pressure chamber using energy generated by movement of the piston rod.

Abstract: A hydraulic suspension strut (30) has a first on-off valve (58) connecting the first and second chambers (42 and 44), and a second on-off valve (62) connected to chamber (42) only. Suspension arm (3) of wheel (1) can be retracted beyond normal road travel, or protracted to road travel mode, by use of pump (9) and valves (58 and 62). The space in the strut above port (56) may be used as a hydraulic bump stop. An accumulator (50) may be included, as a hydraulic spring. Alternatively, strut (70) (FIG. 6; note alternative accumulator position) allows suspension to be raised above normal road travel. Strut (100) (FIG. 8) may be operated in roadgoing raised, or retracted mode. These struts may be applied to reconfigurable suspensions; particularly for amphibious vehicles, which may require wheels to be withdrawn above the hull water line to reduce drag on water, particularly during cornering.

Abstract: A hydraulic circuit controls a doubling acting cylinder of a vehicle suspension to provide load leveling and shock absorption functions. A set of solenoid valves control the application of pressurized hydraulic fluid from a supply line to the cylinder and from the cylinder to a tank return line to raise and lower the vehicle for load leveling. The chambers of the cylinder are interconnected by a parallel arrangement of a check valve, orifice and a relief valve. Another parallel arrangement of a check valve, orifice and a relief valve couples the cylinder to an accumulator. These parallel arranged components enable the doubling acting cylinder to function as a passive shock absorber. A lock-out valve is provided in the preferred embodiment a to defeat the shock absorber operation and provide a very stiff suspension.

Abstract: A suspension system (20) controls the amount of compressible fluid (42) within struts (28) to determine spring rate coefficients (Ks) and dampening coefficients (Bs) for the struts (28). The spring rate and dampening coefficients (Ks, Bs) are selected to provide forces (F) which are a sum of several components, which include a desired target static force (Fd) for balancing various forces acting upon a vehicle chassis, comparison of the target strut force (Fd) to the actual force (F) applied by the respective struts (28), comparison of velocity ({dot over (z)}5) of the chassis relative to a selected reference datum, and a ride height error (erh). Frequency dependant filtering decreases the spring rate coefficients (Ks) when changes in position (Zs) are detected at frequencies (&ohgr;) beneath a threshold level (&ohgr;K), and decreases the dampening coefficients (Bs) when changes in velocity ({dot over (z)}s) are detected at frequencies (&ohgr;) above a threshold level (&ohgr;B).

Abstract: In order to meet the demands of simplicity and reliability in active control systems for flexible structures, an inexpensive active truss element and control law has been developed. A decentralized switching control law is used along with a compressible fluid in the truss element in order to dissipate energy during the motion of the structure. However, the energy is not absorbed in the same manner as a conventional viscous damper. The truss element retains its maximum stiffness, but has a resettable nominal unstressed length. Energy is absorbed in the working fluid of the truss element through heat transfer to the environment when the nominal length is reset at the proper switching times. The control law is insensitive to changes in structural parameters such as mass, stiffness, and damping.

Abstract: The present invention provides a suspension control apparatus which can perform good suspension control regardless of change in temperature. The suspension control apparatus comprises a transistor capable of being turned ON/OFF in response to a level of a PWM signal, a current sensor for detecting current flowing through a proportional solenoid, and a controller for adjusting a duty ratio of the PWM signal on the basis of the comparison between a current data detected by the current detecting means and a previously set reference data to correct command current. The current actually flowing through the proportional solenoid is measured, and the duty ratio of the PWM signal is adjusted to obtain a desired damping force on the basis of the measured current. With this arrangement, if a temperature of the proportional solenoid is increased to increase resistance thereof due to application of current to the proportional solenoid, the applied current is corrected to provide the desired damping force.

Abstract: A suspension control system for use with an automotive vehicle supported on front and rear road pairs of road wheels. Shock absorbers are provided between sprung and unsprung masses of the vehicle at the front and rear road wheel side tower positions for providing variable damping force characteristics. First behaviors of the vehicle at the front road wheel side tower positions are sensed. A predetermined transfer function is used to calculate second behaviors of the vehicle at the rear road wheel side tower positions based, on the sensed first vehicle behaviors. The damping force characteristics of the shock absorbers mounted at the front road wheel side tower positions are controlled based on the sensed first vehicle behaviors. The damping force characteristics of the shock absorbers mounted at the rear road wheel side tower positions are controlled based on the calculated second vehicle behaviors.
