A damping device has a pin member inserted slidably in a cylindrical case member. The bottom of the case member has: a hole forming section in which an insertion hole is formed; and a slit for allowing the hole forming section to be expanded and deformed. The outer peripheral surface of the pin member and/or the inner peripheral surface of the hole forming section has a tapered section tilted relative to the axial direction. The movement of the pin member of being pressed into the insertion hole from the inside causes the outer peripheral surface of the pin member and the inner peripheral surface of the hole forming section to slide on each other along the tapered section, and as a result, the insertion hole is expanded.

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.

A damper rod bushing operatively connects an end member of a gas spring and a damper rod of a damper to at least partially form a gas spring and damper assembly. The damper rod bushing is constructed for exposure to gas pressure within a spring chamber of a gas spring and damper assembly such that pre-load forces due to gas pressure within said spring chamber act on said damper rod bushing. The damper rod bushing can include an outer support element, an inner support element and an elastomeric connector element operatively connected between the outer and inner support elements such that a substantially fluid-tight seal is formed therebetween. A gas spring and damper assembly including such a damper rod bushing, as well as a suspension system including one or more of such gas spring and damper assemblies and a method of assembly are also included.

A suspension system for use with a motorcycle includes a single body having two pneumatic cylinders in axial alignment therein. The suspension system may be sold in a kit, and may be installed in an existing front wheel fork.

A gas spring system includes: a gas spring assembly including at least one gas damping passage; a reservoir member connected to the gas spring assembly, the gas spring assembly being in fluid communication with the reservoir member by way of the at least one gas damping passage; and a guide member coupled with the gas spring assembly, the guide member at least partially enclosing the reservoir member and being configured for sliding axially relative to the reservoir member.

A shock absorber spring retention structure is provided for a remote control car. A spring is arranged between a shock absorption cylinder and a piston rod that are axially movable relative to each other to produce an effect of damping. The spring has a top supported on an adjustment ring that is threadingly screwed to an outer circumference of the shock absorption cylinder and a bottom having a wire rotatably coupled to a clip and held in position by a mounting seat to be coupled to a connection seat mounted to an end of the piston rod. The connection seat includes an engagement section with which the clip is engageable for locking. Thus, in the assembly of the shock absorber, the clip securely retains and couples the spring, the mounting seat, and the connection seat together to prevent the spring from detaching during the operation of the shock absorber.

Suspension system for vehicle seats, in particular for utility motor vehicle seats, comprising at least a first and a second part, the two parts being mounted oscillatorily movable and spring-loaded with respect to one another, wherein a closed hydropneumatic circuit is provided which comprises at least one control element, connected to at least one of the two parts, and at least one first hydropneumatic spring connected in series therewith, a hydraulic pressure of a hydraulic medium in the circuit being convertible into a force acting between the two parts by means of an action surface arranged in the control element, the pressure being dependent on a gas pressure in a gas volume of the first spring.

Methods and apparatus for lubricating suspension seals by pumping fluid to the seals using a compression or rebound action of a suspension component.

A bicycle fork includes a pair of fork leg assemblies, each of the leg assemblies having an upper leg telescopingly engaged with a lower leg. A damping assembly is provided in at least one of the legs. The damping assembly includes lock-out and blow-off compression circuits. These compression circuits are externally adjustable without tools. Furthermore, these two compression circuits may be adjusted independently of each other.

A hydraulic suspension damper includes a tube having an opened end and a closed end defining a compartment. A main piston is disposed in the compartment dividing the compartment into a compression chamber and a rebound chamber. A piston rod is attached to the main piston. A rod guide is disposed at said opened end. A stroke stop arrangement includes an insert and an additional piston attached to the piston rod. The insert has a narrowed section including an inner surface defining at least one recess between the distal end and the rod guide and extends axially along the insert in fluid communication with the compression chamber for allowing working liquid flow from the rebound chamber to the compression chamber during the rebound stroke. The at least one recess includes three recesses disposed equidistantly and spaced from one another.
