A wear sleeve for a shock body is disclosed. The wear sleeve inner diameter (ID) that is larger than an outer diameter (OD) of a shock body. A wear sleeve OD that is smaller than a spring coupler ID, such that the wear sleeve will fit about the outside of said shock body and between the shock body and the spring coupler.

A device for emergency opening of an aircraft door having: a tubular actuating member (7) which includes a first end plate (8) and a second end plate (9); an elastic compression device having a tubular spring (10) compressed between the first end plate (8) and the second end plate (9); an expansion regulator (17, 18) arranged inside the tubular spring (10); a retaining member which includes at least one peripheral attachment connecting the first end plate (8) to the second end plate (9), the peripheral attachment being radially outside the tubular spring (10).

A method and apparatus for a vehicle suspension system gas spring. In one embodiment, a vehicle suspension system gas spring includes a compressible main gas chamber and an additional volume combinable with the main chamber to change a gas spring rate of the system. In one embodiment, a low friction piston seal is created by a flexible seal member.

A vehicle spring assembly includes a cylindrical hollow cover defining an opening at each end. A spring is disposed within the cover, and fittings disposed at each end of the cover are configured to contain the spring within the cover. Each fitting defines an aperture. An elongated damper extends in part within the spring along a direction of elongation. The damper includes a pair of opposing end sections each extending through and projecting from the aperture of one of the fittings. Each end section defines a groove. One end section is connectable to a vehicle tailgate, and the other end section is connectable to a vehicle body. Fasteners securing the fittings to the cover are disposed adjacent the grooves defined in the damper end sections.

An energy absorber reduces an excessive load between an object and an assembly in an overload event. The energy absorber includes an absorber cylinder and a piston device with an absorber piston and a piston rod. A first chamber of an absorber chamber is filled with a field-sensitive absorber fluid. The piston has an absorber valve with an absorber duct extending in an axial direction and being subject to a selective field of a field generating device. A ratio of the outer diameter of the piston rod to an outer diameter of the absorber piston is greater than 0.6 and the first chamber extends in a space around the piston rod. During the relative motion of the fastener and the holding device the field-sensitive absorber fluid is urged through the damping duct of the absorber piston.

An air spring assembly including a damper that extends into an air cylinder float, the damper including a rod positioned having an end affixed to an end cap of the air cylinder float, a first piston affixed to the rod within the damper, a second piston affixed to the damper and having one or more seals on an outer surface thereof that sealingly engage an inner surface of the air cylinder float, wherein when a load applied to the air spring assembly is increased, the second piston and the second end of the damper move towards the end cap compressing air within the air cylinder float, wherein the air cylinder float is a solid member that does not expand as the air pressure within increases during compression, and wherein a protective membrane is positioned on an outer diameter of the air cylinder float.

An adjustable gas shock has a staged softening which includes a gas piston assembly having an gas piston. A piston hollow is formed on the frame and the gas piston is glidingly installed in the piston hollow defining an upper air chamber above the piston and a lower air chamber below the piston. The air piston moves in response to vibrations. A piston shaft hollow is formed on a piston shaft formed on the air piston. The piston shaft hollow has a piston shaft plug glidingly in the piston shaft hollow. The piston shaft plug is spring biased to push air out of the piston shaft hollow. A side opening hollow is formed on the frame. The side opening hollow has a side opening plug glidingly installed in the side opening hollow.

Provided is a single degree of freedom vibration isolator/damper system capable of overload protection. The vibration isolator reduces vibration transmitted to or from an isolated spacecraft component that generates micro-vibrations. The system isolates sensitive components and vibration sources from the spacecraft. The system may consist of a 1) first spring element in series with a first damper element; 2) a second spring element in parallel with the first spring element and first damper element; and 3) a support member that serves as the overload protection device.

A pneumatic suspension system is provided. The pneumatic suspension system includes a pneumatic suspension component configured to be positioned within a fork tube in a front-end motorcycle suspension system. The pneumatic suspension component defines a single body housing having a pneumatic cylinder therein.
