摘要： A landing gear arrangement may comprise a lever configured to be coupled between an axle and a strut piston of a shock strut, a load damper configured to be externally coupled between the shock strut and the lever, wherein the load damper is configured to increase a length of the landing gear arrangement in response to an extension force of the load damper increasing above a ground force reacted through the landing gear arrangement. The load damper may be located externally from the strut piston.

摘要： A spring assembly 100 for aircraft landing gear 10 including: an interface 110 via which the spring assembly 100 is attachable to a support 1a; a loading point 120 for receiving a load from one or more wheels 150 or skids in use, wherein the loading point 120 is movable relative to the interface 110; a spring system 130 that is configured to apply a resilient biasing force to the loading point 120 to oppose movement of the loading point 120 relative to the interface 110. The spring system 130 is configured so that, during application of an increasing load to the loading point 120 against the resilient biasing force of the spring system 130, a spring rate of the spring system 130 changes from a first spring rate k1 to a second spring rate k2, the second spring rate k2 being less than the first spring rate k1.

摘要： An aircraft landing gear 2 is disclosed having a first arm 6a configured to have one or more wheels 8a mounted at one end, the first arm 6a being configured for mounting to a pivot 10a. The landing gear 2 includes a second arm 6b configured to have one or more wheels 8b mounted at one end, the second arm 6b being configured for mounting to a pivot 10b. The landing gear 2 further includes a first link 18a pivotally coupled to the first arm 6a, a second link 18b pivotally coupled to the second arm 6b; and a main link 20 pivotally coupled to each of the first and second links 18a, 18b and to a shock absorber 22 arranged to provide a biasing force via (i) the main linkage 20 and the first link 18a which opposes rotation of the first arm 6a about the pivot 10a and (ii) the main linkage 20 and the second link 18b which opposes rotation of the second arm 6b about the pivot 10b.

摘要： A strut assembly includes a piston and a bearing housing around the piston. The bearing housing may also comprise a groove and a tapered surface opposite the groove. A bearing may be in the groove and proximate the piston. An outer cylinder may be around the bearing housing. The angle of the tapered surface may be based on a deflection angle between the outer cylinder and the piston. A wear plate may be around the tapered surface. An elastic material may be disposed between the tapered surface and the wear plate. The bearing housing may comprise a titanium alloy. The bearing housing may be configured to flex towards the wear plate.

摘要： An aircraft landing gear assembly includes a mechanical structural linkage having a shock absorber and a linkage abutment which are biased apart by a mechanical spring. The force required to deform the spring sufficiently to place the linkage abutment at a predefined distance with respect to the shock absorber abutment is less than the breakout force of the shock absorber.

摘要： Landing gear apparatuses and applications, wherein wheels include embedded (in-wheel) high impact shock absorbing capabilities. Landing gear assembly includes: wheel with wheel rim connected to wheel hub, wheel rim encompasses inner boundary and has inner radius, wheel hub is movable and positionable to a nominal position in space within rim inner boundary; a wheel hub positioning mechanism, connected to wheel hub, selectively confining and positioning wheel hub within space to pre-determined position different from nominal position; and wheel hub suspension assembly, connected to wheel hub, operable in response to hub moving relative to pre-determined position, and including damper for absorbing shocks or/and dissipate kinetic energy during hub motion. When wheel is subjected to landing impact shock at least 2 meters-per-second vertical velocity, hub moves from or across pre-determined position towards rim inner boundary, along wheel hub maximal shifting path longer than rim inner radius. Applicable to various (air-bound) landing vehicles.

摘要： A spring assembly elongate along a longitudinal direction includes a first spring that includes a first spring member and a first elongate member that extends from the first spring member along the longitudinal direction. The spring assembly includes a second spring including a second spring member and a second elongate member that extends from the second spring member along the longitudinal direction. The second elongate member extends through the first spring member, and the first elongate member extends through the second spring member such that the first and second spring members are spaced apart with respect to each other along the longitudinal direction.

摘要： A shock strut includes a first cylinder defining a first volume. The shock strut includes a first piston head moveably positioned within the first volume and defining a first fluid chamber and a third fluid chamber within the first volume. The shock strut includes a second cylinder defining a second volume. The shock strut includes a second piston head moveably positioned within the second volume and defining a second fluid chamber and a fourth fluid chamber within the second volume. The fourth fluid chamber is in fluid communication with the third fluid chamber. The shock strut also includes a bleed port. The shock strut also includes a tube extending from the fourth fluid chamber through the second piston head and the second fluid chamber to the bleed port.
