摘要： PROBLEM TO BE SOLVED: To provide a suspension device capable of changing spring force. SOLUTION: This suspension device has a controlling means 16 for responding to at least a sensed change of signals showing operation parameters while operating a vehicle and changing at least one of spring force and damping force. A liquid spring means 12 has spring characteristics and damping characteristics corresponding to the volume and the pressure of liquid. The spring force is changed through a spring rate adjusting means achieved by the controlled change of the effective volume of compressing liquid in the liquid spring means 12 using the spring rate adjusting means 96. A vehicle suspension device 10 includes the liquid spring 12 which generates the spring force and the damping force capable of being compressed by and resisting to the wheel displacement in the vertical direction against a body frame 14 by using the compressing liquid internally for each wheel. The spring and damping characteristics of each liquid spring 12 are adjusted by a computer 16 while operating the vehicle according to the change sensed by variable liquid springs and vehicle operation parameters.

摘要： A vibration control system for a structure having a first structural member and a second structural member. The vibration control system having a liquid spring operably interposed between the first structural member and the second structural member. The liquid spring uses a compressible liquid to seamlessly generate spring and/or damping forces in the suspension system in response to relative displacement between the first structural member and the second structural member. A second volume of compressible liquid is located in a second chamber. The second volume is removably connected to the liquid spring by a fluid passage. A valve is coupled to the fluid passage, the valve selectively operable to place the second volume in communication with the liquid spring. A controller is electrically coupled to the valve. The controller emitting a control signal to control the valve.

摘要： A resilient expandable pressure vessel configured to function like a spring. The resilient expandable pressure vessel includes a body portion, a cavity defined within the body portion, and at least one port in communication with the cavity defined in the body portion. The at least one port is configured to receive a fluid into the cavity and discharge the fluid from the cavity. The resilient expandable pressure vessel has a predetermined expansibility across a range of operating pressures of the fluid in the cavity. The range is at least 200 psi.

摘要： A suspension system configured to exhibit low variance in vehicle ride frequency over a large range of vehicle loads. The suspension system includes a strut having a cylinder and a piston configured to reciprocate in the cylinder. The suspension system also includes a vessel coupled to the strut, and a valve in an interior chamber of the vessel. The valve divides the interior chamber into a first liquid volume and a second liquid volume. The suspension system also includes a hydraulic accumulator having a volume and a liquid volume. The suspension system further includes a compressible liquid in the cylinder, the first liquid volume in the vessel, and the second liquid volume in the vessel, and a spring element in the volume of the hydraulic accumulator.

摘要： A vibration control system having a liquid spring (510) positioned between a vehicle frame and a vehicle wheel(502). The liquid spring (510) uses a compressible fluid to seamlessly generate spring and/or damping forces in the vibration control system in response to relative displacement between the frame and the wheel (502). A second volume of compressible liquid (518) is connected to the liquid spring (510) by a fluid passage (520). A valve (522) is coupled to the fluid passage (520) and is selectively operable to place the second volume (518) in communication with the liquid spring (510). A controller (540) is electrically coupled to the valve (522) and emits a control signal to control the valve (522) in response to signals from vehicle sensors (550, 552, 554).
