摘要： A damper comprises an inner tube having a longitudinal axis with a piston slidably disposed in the inner tube. An outer tube surrounds the inner tube and defines a fluid chamber therebetween. A first valve assembly includes a first valve ring and a first valve disc fixed to the first valve ring. The first valve disc covers a first passageway to restrict flow therethrough in a first direction and allow flow in an opposite second direction. A second valve assembly includes a second valve ring and a second valve disc fixed to the second valve ring. The second valve disc covers a second passageway through the second valve ring to restrict flow therethrough in the second direction and allow flow in the first direction. The first valve assembly is axially spaced apart from the second valve assembly.

摘要： A method and apparatus for a damper. The damper comprises a fluid chamber having a piston dividing the chamber into a compression and rebound sides, a reservoir in fluid communication with the compression side of the chamber, and an isolator disposed between the compression side and the reservoir, whereby the isolator obstructs fluid flow between the compression side and the reservoir. In one embodiment, a bypass provides a fluid path between the compression side and the isolator.

摘要： 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.

摘要： A cylinder-piston unit with load-dependent damping includes a piston longitudinally displaceable in a cylinder. The piston has a first piston channel and a second piston channel, which each connect a compensation space on one side of the piston to a displacement space side on an opposite side of the piston. On the displacement space side a throttle channel connects one first piston channel to the piston lateral surface. On its displacement space side the piston has a piston journal, which carries a resiliently deformable piston disc. The piston disc is displaceable and covers the throttle channel at least partially. The displacement space side has at least one relief portion deviating from a piston end face plane. The relief portion is delimited on a number of sides by a plurality of boundary lines running concentrically with respect to the central axis. Each of these boundary lines can be differentiated continuously.

摘要： A shock absorber is provided that includes a shock body and a shaft assembly. The shock body has an inner chamber. The inner chamber is defined by a cylindrical interior surface. At least one groove is formed in the interior surface within at least one select length of the shock body. A piston of the shaft assembly is received within the inner chamber of the shock body. The piston includes valving to allow dampening matter that is received within the inner chamber to pass through the piston to allow the piston to move within the inner chamber. The at least one groove that is formed within the interior surface is configured to allow at least some of the dampening matter to bypass the valving of the piston to allow the piston to move through the at least one select length with less resistance.

摘要： A hydraulic damper assembly comprises a main tube defining a fluid chamber. An external tube extends about the main tube defining a compensation chamber between the main and external tubes. A main piston, located in the main tube, divides the fluid chamber into a compression chamber and a rebound chamber. A piston rod couples to the main piston. A base valve, located in the compression chamber, couples to the main tube. A hydraulic compression stop, located in the compression chamber, includes an additional piston, an insert, and a fixing member. The additional piston couples to the main piston. The insert, located in the compression chamber, couples to the base valve. The insert has a main section and a terminal section. The terminal section having an external diameter that is less than an external diameter of the main section.

摘要： A suspension element includes a main body having an end cap defining an internal volume and a tubular element slidably engaged with the main body. The suspension element further includes a first piston and a flow control element. The flow control element is configured to prevent movement of the tubular element relative the main body in a direction. The suspension element may further include a locking member and a piston. The locking member may be configured to engage a barrier of the main body when the first piston traverses at least a predetermined distance towards the end cap. The locking member may be affixed to the tubular element and may fully surround the tubular element. Together the flow control element and the locking member are configured to prevent movement of the suspension element.

摘要： A hydraulic damper for a vehicle including a main tube. A first piston assembly is slideably disposed in the main tube and axially divides the main tube into a rebound chamber and a primary compression chamber. A hydraulic compression stop assembly is disposed in the primary compression chamber and includes a narrowed section extending between an open end and a closed end. A second piston assembly is slideably disposed in the narrowed section and is coupled with the first piston assembly. The second piston assembly has a piston tube that extends between an opened end and a shut end. A displaceable partition is slideably disposed in the piston tube. A first auxiliary compression chamber is defined between the partition and the closed end of the narrowed section. A second auxiliary compression chamber is defined between the partition and the shut end of the piston tube.
