摘要： A suspension system includes a hydraulic cylinder having a piston chamber in which a piston moves and a rod chamber in which a rod moves. The hydraulic cylinder operably moves between a retraction and an extension. The system also includes a throttle valve, a branching, and a hydraulic reservoir fluidly coupled to the hydraulic cylinder. A fluid flow from the piston chamber is divided at the branching into a first fluid flow portion and a second fluid flow portion. The first fluid flow portion flows to the rod chamber of the hydraulic cylinder, and the second fluid flow portion flows through the throttle valve to the hydraulic reservoir.

摘要： A gas spring for a vehicle suspension system includes a cylinder, a rod disposed within the cylinder, the rod and the cylinder at least partially defining a chamber, and an accumulator in communication with the chamber. The rod and the cylinder are configured such that a relative movement therebetween changes the volume of the chamber. Gas in the chamber and the accumulator are configured to cooperate to at least partially provide a spring rate that varies based on at least one of a deflection and a spring force associated with at least one of the rod and the cylinder.

摘要： An accumulator is provided, which is aimed at stabilization in mounting state of a damping member while diminishing the impact on a metal bellows. In an accumulator (100), a damping member (190) formed slidably at the inner circumferential surface of a pressure vessel (110) and suppressing the oscillation of a metal bellows (130) while keeping a gap between the metal bellows (130) and the inner circumferential surface of the pressure vessel (110) is mounted at at least one site of a plurality of annular valley parts of the metal bellows(130) including a plurality of annular crest parts and the plurality of annular valley parts alternately formed therein. In the damping member (190), a radially inward tip is fitted with the valley part, and a radially outward tip is longer than the crest part of the metal bellows radially and outwardly.

摘要： Altering the damping rate of a vehicle suspension damper. A pressure of a damping fluid is exerted against a second valve mechanism connected to the vehicle suspension damper. The pressure of the damping fluid is increased beyond a threshold of the second valve mechanism that is adjustable by an adjustment member. The adjustment member is exposed through a high pressure side of the vehicle suspension damper. The second valve mechanism is then opened.

摘要： A bicycle shock absorber and methods for differentiating between rider-induced forces and terrain-induced forces includes a first fluid chamber having fluid contained therein, a piston for compressing the fluid within the fluid chamber, a second fluid chamber coupled to the first fluid chamber by a fluid communication hose, and an inertial valve disposed within the second fluid chamber. The inertial valve opens in response to terrain-induced forces and provides communication of fluid compressed by the piston from the first fluid chamber to the second fluid chamber. The inertial valve does not open in response to rider-induced forces.

摘要： A variable dashpot for motor vehicles. It comprises a vibration-suppressing piston-and-cylinder mechanism. The cylinder contains displacement fluid. The piston divides the cylinder into two displacement compartments. The piston has a piston rod attached to it. The piston is provided with pressure-dependent valves that vary the level of vibration suppression. The vibration-suppression valve system has two vibration-suppressing valves (2) accommodated in alignment in a cylindrical valve housing (1). Each vibration-suppressing valve consists of an axially displaced electromagnetic plunger (5 or 6) that operates in conjunction with at least one outlet (3 or 4) and of at least one pressure-sensitive valve (7 or 8) on stream parallel or in alignment with the plunger.

摘要： A moved mass of hydraulic medium is used as a compensating mass at critical frequencies of the suspension system to achieve a frequency-selective dynamic damping, and a suitable hydraulic transmission ratio can ensure that a relatively small quantity of hydraulic medium is moved at high speed in order to achieve a good compensating effect, despite the low mass of moved hydraulic medium. A displacement unit can be connected to the sprung mass via an elastic bearing part and to the associated spring accumulator via a hydraulic line. The spring constant of the bearing part, the mass of that part of the displacement unit or of the spring unit mounted on the bearing part, the cross-section of the hydraulic line and its length, the effective cross-section of the displacement unit and the density of the hydraulic medium are so sized that the resonant frequency of the spring unit is near a critical frequency of the suspension system, for example near the frequency of the axle resonance of a vehicle. Alternatively, the displacement unit can be connected to a first spring accumulator which is connected to a second spring accumulator via a hydraulic channel. The length and cross-section of the channel are so coordinated with the density of the hydraulic medium and with the characteristics of the spring accumulators that the natural frequency of vibrations of the fluid mass in the channel coincides at least approximately with one of the critical frequencies of the suspension system.
