A method of assembling an accumulator for a suspension damper where the method includes the steps of forming an outer shell of an accumulator, assembling a bellows assembly by connecting distal and proximal plates to opposite ends of an annular bellows wall, and inserting the bellows assembly into the outer shell. The outer shell is formed such that it includes a distal end with an end wall and an open end opposite the distal end. The bellows assembly is inserted into the open end of the outer shell with the distal plate facing the end wall of the outer shell. The method proceeds with coupling the distal plate of the bellows assembly to a stem of a gas charging port on the end wall of the outer shell at a fixed axial position using a fixation component that engages the stem of the gas charging port.

A bumper cap for a damper, the damper including an outer tube with a tube end. A rod extending through the tube end. The damper including a damping fluid, such as a hydraulic oil, that is movable within the damper in response to movement of the rod to provide a damping effect. The bumper cap has a cup shaped body having a side wall and a base, the side wall having an inner surface and an outer surface, the inner surface having a dimension that is sized to be press fit over the outer tube. The base of the bumper cap has a through hole in the base, the through hole configured to have the rod pass therethrough. The base has at least one fluid passage extending away from the through hole that is in fluid communication with a fluid reservoir in the side wall.

An electronically controller external damper reservoir assembly (eRESI) can be connected to a passive damper and/or substituted for an existing external reservoir to provide semi-active damping control. The eRESI includes a reservoir and a variable base valve assembly actuated by an actuator. A controller is in communication with the actuator and a sensor providing input signal indicative of vehicle movement and is programmed to generate a damping control signal to the actuator based on the input signal, to dynamically control the damping force outputted by a passive damper hydraulically connected to the eRESI. A P/T sensor can be installed to a gas chamber of a vehicle damper to generate a P/T signal indicative of the pressure and temperature of the gas. The controller is programmed to determine a damper position of the damper based on the P/T signal.

A damper includes a pressure tube extending about a longitudinal axis and defining an inner volume. The damper includes a piston attached to a piston rod and slidably disposed within the pressure tube. The piston divides the inner volume of the pressure tube into a first working chamber and a second working chamber. The damper includes a fluid connector having a first wall and a second wall, each elongated along the longitudinal axis and sealed to the pressure tube. The fluid connector has a third wall elongated along the longitudinal axis and extending from the first wall to the second wall. The pressure tube defines an opening at the first working chamber, and the third wall of the fluid connector defines an opening spaced from the opening of the pressure tube. The first wall, the second wall, and the third wall define a passage extending from the opening of the pressure tube to the opening of the third wall.

A damper assembly includes an outer tube and an inner tube disposed in the outer tube defining a fluid space therebetween. The inner tube defines an inner volume. A piston is slidably disposed in the inner tube and divides the inner volume into a rebound working chamber and a compression working chamber. An active rebound valve is fluidly connected to the rebound working chamber and the fluid chamber, and an active compression valve is fluidly connected to the reserve chamber and the compression working chamber. An intake assembly is positioned in the fluid chamber to control the fluid flow through the active rebound valve and into the compression working chamber during a rebound stroke and to control fluid flow from the compression working chamber through the active compression valve and into the rebound working chamber during a compression stroke.

A method of manufacturing a damper tube is provided. The method includes providing a tube having a first end and a second end opposite to the first end. The method includes providing a reinforcing insert, at least partly, within the first end of the tube. The method includes flattening a portion of the first end of the tube. The method also includes bending at least one of the reinforcing insert and the flattened portion of the first end of the tube into a loop. The method further includes connecting an edge of the loop to the tube.

The front fork of the present invention has a wheel-side bracket that closes another end of an inner tube which is movably inserted inside an outer tube from one end thereof; a cylinder provided inside the inner tube; and a head member that is fitted to the cylinder side on the opposite side from the wheel-side bracket, in which the cylinder and the head member are sandwiched, while subjected to an axial force, by a fastening portion formed on the inner tube and the wheel-side bracket.

An adjustable vibration damper for a vehicle may include an outer tube, an intermediate tube, and an inner tube arranged coaxially. A concentric compensation chamber between the outer tube and the intermediate tube may receive a hydraulic fluid and a gas. A piston rod may include a piston disposed movably in the inner tube and dividing an interior of the inner tube into first and second working chambers. The adjustable vibration damper may also include first and second damper valves arranged on an outer wall. The first working chamber may be fluidically connected to the compensation chamber by the first damper valve for adjustment of a pressure stage, and the second working chamber may be fluidically connected to the compensation chamber by the second damper valve for adjustment of a traction stage.

A shock absorber pressure tube defining a working chamber is provided. A piston assembly coupled to a piston rod is slidably disposed in the pressure tube and divides the working chamber into upper and lower working chambers. A reserve tube surrounds the pressure tube to define a reserve chamber. A base valve assembly, position at one end of the pressure tube, controls fluid flow between the lower working chamber and the reserve chamber. The reserve tube comprises first and second open shells that are joined together at longitudinal seams to create a substantially cylindrical shape. The first and second open shells may be made from patchwork blanks, tailor welded blanks, tailor rolled blanks, or tailor heat treated blanks to give different portions of the first and second open shells different thicknesses, strengths, properties, or characteristics.

This assembly includes a plurality of stacked circular members, and a fixing pin that is disposed inside each of the circular members to arrange and integrate each of the circular members in an axial direction thereof. The fixing pin includes a shaft portion extending in the axial direction, a flange portion extending radially outward from one end side of the shaft portion, a recessed portion that is provided on an end face of the shaft portion on the other side and has a non-circular cross-section orthogonal to the axial direction, and one or a plurality of protruding portions that are provided on an outer circumferential portion of the shaft portion on the other end side and protrude radially outward from an inner circumferential surface of each of the circular members.
