摘要： 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 dampmening coefficients (KS, BS) are selected to provide foraces (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 (żS) 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 (ω) beneath a threshold level (ωK), and decreases the dampening coefficients (BS) when changes in velocity (ZS) are detected at frequencies (ω) above a threshold level (ωB).

摘要： A suspension damper (10) includes a housing bounding a main chamber. A piston rod (34) is slideably disposed within the main chamber of the housing. A main piston (38) is mounted on the first end of the piston rod within the main chamber of the housing so as to slideably engage against the housing in sealed engagement, the main piston having a first side and an opposing second side with a compression port extending therebetween. A control valve assembly is disposed within the main chamber and bounds a sealed valve compartment. The control valve assembly (100) is movable between a first position wherein the valve compartment is compressed to a first volume and a second position wherein the valve compartment is expanded to an enlarged second volume, the control valve assembly being movable under pressure so as to provide variable compression damping properties.

摘要： The invention relates to a pressure control system capable of adapting to different load situations, having a hydraulic acculmulator (14), whose prestress pressure can be regulated via a control device (22) having a supply device (34). The hydraulic accumulator is connected to at least one hydraulic drive, whose pressure characteristic can be adjusted by controlling the prestress pressure of the hydraulic accumulator (14) via a working medium in the control device (22). The invention is characterized in that the control device (22) has a control unit (32) with a pressure sensor (36) for determining the prestress pressure. This control unit (32) alternately increases and decreases the quantity of the working medium in accordance with the load situation. By varying the prestress pressure, the spring characteristic can be constantly adapted to the most varied axle load conditions.
