    摘要: A torque link includes a spring-damper system structurally incorporated into the design and functionality of the torque link. The spring portion may take the form of a structurally rigid beam (108) while the damping portion may take the form of a damping mechanism or assembly (110). The damping mechanism is configured to damp out deformations in the beam and also configured to bottom out and become a structural tension/compression member when the load through the torque link exceeds a threshold load. The method damping may take a number of forms, such as, but not limited to, solid media damping, fluid damping with or without an orifice, a hydraulic or magnetic circuit, coulomb damping, etc.

    摘要: A hydraulic shimmy damper that resolves drawbacks in several known shimmy dampers, such as damping characteristics that are dependent on oil temperature variations. The disclosed shimmy damper includes a hydraulic compensator (40) having an internal fluid volume that is significantly more important than a fluid volume expelled from the body of the shimmy damper when its piston moves fore and aft. The shimmy damper also includes a hydraulic manifold (30) arranged between the body and the hydraulic compensator and defining a transfer channel between chambers in the piston that is connected to the hydraulic compensator. The manifold receives interchangeable hydraulic cartridge-type valves (CV1,RV1; CV2,RV2) for metering the fluid flowing from the chambers to the transfer channel, and allows the fluid to freely enter the chambers from the transfer channel. The present shimmy damper is therefore much less sensitive to oil temperature variation under intense shimmy.

    摘要: The present disclosure provides an axial engagement-controlled variable damper comprising a rotor assembly (240, 540, 640) coupled to a rotor shaft and disposed about an axis of rotation and a stator (220, 520), coaxially aligned with the rotor assembly. The axial engagement-controlled variable damper may further comprise a flux sleeve (250), axially movable relative to the rotor assembly between at least a first position and a second position. The flux sleeve (250) may comprise a circumferential flange portion disposed radially between the rotor assembly and the stator, and may be configured to alter magnetic coupling between the stator and the rotor assembly in response being moved axially. The axialengagement controlled variable damper may be configured to generate a first drag torque in response to the flux sleeve being in the first position and a second drag torque in response to the flux sleeve being in the second position.

    摘要: A system for damping vibration and/or shimmy of a landing gear system is disclosed. The system is a friction-based damping system 22 that utilizes a friction pad 28 and friction wedge 32 to dampen vibration and/or shimmy. The friction pad may be coupled to an apex pin 24 that is used to couple a first torque link 16 and a second torque link 18 together. The friction wedge may be a made of a wearable and/or consumable material.
