    摘要: A telescopic device (10, 30) comprising: a housing (12) having an inner side wall surface defining a bore (B) with an open end; a rod (14) having an end slidably mounted within the bore to linearly move relative to the housing along a longitudinal axis between an extended position, where the telescopic device is relatively long, and a retracted position, where the telescopic device is relatively compressed; a first bearing (16) and a second bearing (18) each defining a bearing surface arranged to provide sliding engagement between the rod and housing, the first bearing being mounted relatively close to the open end of the bore and the second bearing being mounted relatively far from the open end of the bore relative to the first bearing, wherein the second bearing is annular in shape with a central axis, the bearing has a radially outer mounting surface of arcuate cross-section and a radially inner bearing surface for sliding engagement with an outer surface of the rod and wherein the inner sidewall is provided with an annular groove having a second mounting surface of arcuate cross-section to house and retain the second bearing.

    摘要: The present disclosure includes landing gear components, such as an outer cylinder (104) of a shock strut assembly (102). The outer cylinder (104) includes one or more structural attachment pins (105) configured to engage with other components of the landing gear including pintle frames (110), drag braces (106), and torque links (124). The pins (105) include a cobalt alloy mated to a cobalt containing coating (140) for improved wear resistance, which may eliminate the need for a bushing between the pin (105) and the receptacle (107) of the corresponding landing gear component.

    摘要: A shock strut (100) for a vehicle includes a housing (130) with a through channel (131) and a motor mount (134), and a motor (150) fixed to the housing (130). The cylinder (106) of a shock strut (100) is configured to define a lead screw (107) on its outer surface. The cylinder (106) extends through the housing (130). The piston (104) of the shock strut (100) is attached to a ground engaging assembly (110). A gear nut (140) rotatably mounted in the housing (130) threadably engages the threaded cylinder (106), and is configured to be driven by the motor (150). The housing (130) is attached to the vehicle, and the gear nut (140) is controllably rotated to extend and retract the shock strut (100). A sensor (155) provided on the assembly monitors the position of the shock strut (100). A torsion link assembly (120) reacts rotational forces on the cylinder (106).

    摘要: A torque link member for aircraft landing gear includes a first end for connecting to a lower portion or an upper portion of the aircraft landing gear and a second end for connecting to another torque link member. A locking pin is disposed on one of the upper portion, the lower portion, the first end or the second end. The locking pin is axially movable between an engaged position wherein the pin protrudes for interengagement with a cooperating aperture on the first end, the second end, the upper portion, the lower portion, or the second end of the other torque link member, and a disengaged position. The locking pin is biased toward the engaged position and movable against the biasing to the disengaged position.

    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: Methods for servicing shock struts (104;210) are provided. In various embodiments, a method for servicing a shock strut (104;210) may comprise deflating the shock strut (104;210); compressing the shock strut (104;210) until the shock strut (104;210) is in a fully compressed position; and charging the shock strut (104;210) with a liquid until a pressure of the liquid decreases a volume of a residual air located inside of the shock strut (104;210). In various embodiments, charging the shock strut (104;210) with liquid under pressure may reduce the volume of trapped air inside of the shock strut (104;210) to a negligible volume, eliminating the servicing variations.
