ABSTRACT:
A double acting hydraulic actuator in an active vehicle suspension control is connected to the sprung mass through a bushing allowing limited movement therebetween. A piston in a bore within the upper housing of the actuator forms a control chamber with and outlet orifice. The piston has a finger engaging the sprung mass and thus being driven downward with a sharp upward road disturbance that causes compression of the bushing. The increase of pressure in the control chamber due to the flow limiting of the orifice activates a valve which opens the activating chambers of the actuator to each other while the pressure exceeds a predetermined pressure. Thus the hydraulic actuator is quickly unloaded to absorb sudden road disturbances and prevents them from being transmitted directly through the incompressible fluid of the actuator to the sprung mass before the main suspension control can react.
