Assemblies, systems, devices, and methods for disassembling an original equipment manufacturer (OEM) air shocks/air springs and replacing the inflatable bag/bladders and adding a crimp ring adapter to a top mount in order to reassemble and remanufacture the air shock/air spring with a new inflatable bag/bladder as an effective high quality and good reliability OEM replacement part. The existing air bladder is substantially cut out form the OEM air shocks/air springs, leaving a portion of the existing air bladder left inside of the remanufactured air shock/air spring.

Assemblies, systems, devices, and methods for disassembling an original equipment manufacturer (OEM) air shock/air spring and reassembling and inexpensively remanufacturing the air shock/air spring with a novel seal pack in the top mount. The novel seal pack keeps compressed air from leaking from the air shock/air spring and allows the damper rod to move axially and rotationally and shift side to side in the top mount. The seal pack can include a seal pack with an outer groove, a seal pack X-ring for fitting inside of the seal pack, and an O-ring for fitting into the outer groove of the seal pack.

A suspension system for a vehicle includes a housing; a damper part disposed within the housing and to extend through the housing; a transfer part surrounding the damper part and coupled to the damper part; a damper mount coupled to the transfer part, and disposed between an inner wall of the housing and the transfer part and configured to absorb vibration of the transfer part; a fixing part stacked over the damper mount and fixed to the inner wall of the housing; and an anti-leakage part coupled to the fixing part and configured to prevent an air leakage between the fixing part and the damper mount.

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.

Pressure-sensitive vales are incorporated within a dampening system to permit user-adjustable tuning of a shock absorber. In one embodiment, a pressure-sensitive valve includes an isolated gas chamber having a pressure therein that is settable by a user.

End member assemblies having a longitudinal axis are dimensioned for securement to a flexible spring member. The end member assemblies include a first end member with a first surface portion and a plurality of projections disposed in peripherally-spaced relation to one another about the longitudinal axis. A second end member includes a plurality of grooves dimensioned to receive one of projections. Gas spring and damper assemblies include a damper assembly and a gas spring assembly that includes an end member assembly as well as an end member assembly with a flexible spring member secured between the end member assemblies. A suspension system including one or more gas spring and damper assemblies is also included.

A vehicle height adjusting apparatus for adjusting a height of a vehicle body of a vehicle is provided. The vehicle height adjusting apparatus includes an electric motor provided with a stator and a rotor and formed to have a structure in which a central portion thereof is penetrated; a screw nut fixed to the rotor of the electric motor and provided with a threaded portion on an inner peripheral surface thereof; a screw shaft inserted into and coupled to the inner peripheral surface of the screw nut and provided with a corresponding threaded portion having a shape corresponding to the threaded portion of the screw nut on an outer peripheral surface thereof; a guide portion configured to guide a relative movement between the screw nut and the screw shaft in a longitudinal direction.

An air spring includes a closing member, a rolling piston, and an air spring bellows connected to the rolling piston and the closing member to form a fluid-filled pressure chamber. A level control system for supplying and/or discharging fluid may be integrated into the pressure chamber to control level position based on air spring stroke. The level control system may have a control valve and an actuator connected to the control valve. The actuator may include a guide tube coupled to the rolling piston or closing member, and movably arranged within the pressure chamber. An actuating member may include a pin member and may operate the control valve. A compression spring may have a central spring and a biasing spring, and the guide tube may include a control flange coupled to the pin member, and the biasing spring may be supported to press the pin member against the control valve.

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.

A suspension includes: a cylinder; a piston rod including a piston provided at one end-side, and inserted in the cylinder together with the piston; an outer tube part opened at the one end-side, a position of which relative to the piston rod is fixed at the other end-side, and configured to receive therein at least a part of the cylinder; and a tubular rolling diaphragm having one end disposed at the cylinder and the other end fixed to the outer tube part, and configured to roll in conjunction with displacement of the piston rod with respect to the cylinder. The rolling diaphragm becomes convex toward the other end-side of the outer tube part and is accommodated in the outer tube part, upon contraction of the suspension.
