Shock absorber with hydraulic load regulation simultaneously depending on speed and frequency
The present disclosure relates to a shock absorber with hydraulic load regulation with a rod ending in a pin, which incorporates a longitudinal channel such that the shock absorber includes a frequency amplifier which, in turn, includes a housing, a floating piston which slides along the inside of the housing achieving a seal, and a pressure control valve, wherein the pressure control valve is configured to open when the amplifier chamber reaches a certain pressure level, enabling the outlet of fluid from the amplifier chamber such that the pressure of the amplifier chamber acts on the floating piston, which moves to regulate the flow of fluid through the piston by means of an elastic element acting on valves.
Electronically controlled external damper reservoir
An electronically controller external damper reservoir assembly (eRESI) can be connected to a passive damper and/or substituted for an existing external reservoir to provide semi-active damping control. The eRESI includes a reservoir and a variable base valve assembly actuated by an actuator. A controller is in communication with the actuator and a sensor providing input signal indicative of vehicle movement and is programmed to generate a damping control signal to the actuator based on the input signal, to dynamically control the damping force outputted by a passive damper hydraulically connected to the eRESI. A P/T sensor can be installed to a gas chamber of a vehicle damper to generate a P/T signal indicative of the pressure and temperature of the gas. The controller is programmed to determine a damper position of the damper based on the P/T signal.
Aircraft landing gear shock absorber assembly
An aircraft landing gear shock absorber assembly having: an outer cylinder having a bore which extends into the outer cylinder, the bore defining an opening in the outer cylinder; a sliding tube having a first end region slidably coupled within the bore and a second end region which projects out of opening; a ground fitting distinct from the sliding tube; and a mechanical fixing arranged to mechanically couple the ground fitting to the second end region of the sliding tube, wherein the sliding tube comprises a tubular body portion formed from a ceramic coated fibre composite tube.
Damping valve and shock absorber
A damping valve includes a valve disc including a passage and a valve seat configured to surround an outlet end of the passage, a leaf valve configured to separate from/sit on the valve seat to open/close the passage, and a biasing part configured to exert a variable biasing force on the leaf valve toward the valve disc, and a gap is provided between the leaf valve and the valve seat.
KINETIC SEAT ASSEMBLIES HAVING DAMPERS FOR FIXED COMPONENTS AND MOVABLE COMPONENTS INCLUDING LATERAL DAMPING MECHANISMS AND FLUID RESERVOIRS
A kinetic seat assembly includes a primary seat cushion frame, a secondary seat cushion frame movable relative to the primary seat cushion frame, a primary seat back frame, a secondary seat back frame movable relative to the primary seat back frame, a pair of lateral dampers extending between the primary seat back frame and the secondary seat back frame, a pair of vertical dampers extending between the secondary seat back frame and the primary seat cushion frame, a pair of fluid reservoirs for providing a fluid into the pair of lateral dampers and the pair of vertical dampers, and an electronic control unit configured to control the rate at which the fluid is provided to and drawn out of each of the dampers to control a damping effect. In embodiments, an end of the lateral dampers is permitted to move freely relative to the secondary seat back frame.
SHOCK ABSORBER
A shock absorber including: a first cylinder having an interior, first and second ends and defining an axis, wherein the interior includes a damping fluid chamber and a damping piston movably mounted therein for movement between the first and second ends, wherein the damping piston is mounted on a first end of a shaft, wherein the first end of the shaft is movably retained within the interior of the first cylinder; first and second bypass openings configured for opening into the damping fluid chamber at first and second axially spaced-apart positions; a bypass channel fluidly coupling the first and second bypass openings; a fluid metering valve; and a floating piston dividing a portion of the shock absorber into a gas chamber and the reservoir chamber, wherein the fluid metering valve and the floating piston define the reservoir chamber there between.
Suspension strut
A suspension strut for a vehicle comprises: a first connector for connecting to a first point on the vehicle; a second connector for connecting to a second point on the vehicle; and a damper assembly adapted to provide a damping force as fluid flows through the damper assembly during relative compression between the first point and the second point, wherein the damper assembly comprises a side wall and a damper aperture in the side wall, wherein the damper aperture is open throughout operation of the strut to allow fluid to flow through the damper assembly.
GAS PISTON ACCUMULATOR
A gas piston accumulator with a piston-cylinder unit, the hydraulic space of which can be connected to a hydraulic line. A pressure piston biased with a biasing force acts on the hydraulic space in order to pressurize the hydraulic fluid in the hydraulic line with an accumulator pressure. The biasing force is achieved by a gas pressure in a gas space which is separated from the hydraulic space via the pressure piston, at least one cylinder base of the gas piston accumulator being assigned to the pressure piston as a mechanical stop, and the pressure piston having an axially set back piston main body, on the gas side of which and/or on the hydraulic side of which there protrudes a stop structure which is of reduced area compared to the respective pressure piston side and which can be brought into pressure contact with the cylinder base.
HYDROPNEUMATIC SUSPENSION COMPONENT
The invention relates to a hydropneumatic suspension component such as a gas charged damper. The invention further relates to a floating piston for a hydropneumatic suspension component. Uses of adsorbent material and/or open-cell foam are also disclosed.
Telescopic damper assembly
A damper assembly comprises a main tube extending along a center axis between a first end and a second end defining a fluid chamber. A main piston is disposed in the fluid chamber dividing the fluid chamber into a compression chamber and a rebound chamber. A piston rod extends along the center axis coupled to the main piston. An external tube extends about the main tube and defines a compensation chamber therebetween. The external tube includes a protrusion extending radially inwardly from an opened end to abut the main tube. An external piston is located in the compensation chamber and coupled to the main tube, dividing the compensation chamber into a first compartment and a second compartment. The first compartment extends between the protrusion and the external piston for containing a working fluid. The second compartment extends between the closed end and the external piston for containing a gas.
