摘要： A gas cup (36) is slidably disposed in the main chamber (34) of a housing (20) and a piston (50) is disposed spaced apart from the gas cup (36). The gas cup (36) includes a volume reducing device (110) for forcing a lubricant from a closed lubricant chamber (112) through a lubricant passage (108) to a lubricant reservoir (106) in response to a sliding movement of the piston (50). A flexible diaphragm (116) flexes into the closed lubricant chamber (112) in response to the sliding movement of the piston (50). A seal cap (118) sandwiches the flexible diaphragm (116) between the seal cap (118) and an annular projection (114) and the seal cap (118) includes a plurality of seal ports (120) for forcing the lubricant to flow from the closed lubricant chamber (112) through the lubricant passage (108) to the lubricant reservoir (106). The seal cap (118) includes a skirt (122) retained on the annular projection (114). A fluid seal (104) is disposed about the skirt (122) and spaced apart from the gas cup (36) to define the lubricant reservoir (106).

摘要： A rotary damper assembly comprises a housing extending along a center axis. The housing includes an upper portion and a lower portion. The lower portion defines a fluid chamber. The upper portion defines a compartment in communication with the fluid chamber. The magnetic field generator includes a magnetic core located between the upper portion and the lower portion. The magnetic core extends along the center axis between the upper portion and the lower portion. At least one coil extends about the magnetic core. A shaft extends along the center axis through the upper portion and the magnetic core and into the fluid chamber to facilitate magnetorheological fluid flow from the compartment to the fluid chamber. The magnetic field generator includes an insert, containing a permanent magnetic material, for generating a permanent magnetic field to change viscosity of the magnetorheological fluid.

摘要： A magneto rheological damper includes a housing extending between a first opened end and a second opened end and defining a fluid chamber extending therebetween. An end cap is located at the first opened end and coupled to the housing. A piston is disposed in the fluid chamber dividing the fluid chamber into a compression chamber and a rebound chamber. A piston rod extends along the center axis and attaches to the piston for movement with the piston between a compression and a rebound stroke. A magnetic field generator is located in the compression chamber and in an abutment relationship with the end cap. An extension portion protrudes radially outwardly from the housing and defining a compensation chamber and a channel. The channel is in fluid communication with the compression chamber and the compensation chamber for allowing the working fluid to flow from the compression chamber to the compensation chamber.

摘要： A damper assembly comprises a main tube defining a fluid chamber. The main tube includes a first section, a second section, and an intermediate portion. A sleeve is disposed about the main tube. An external tube is disposed about the main tube and the sleeve. The external tube defines a compensation chamber between the sleeve and the external tube. A main piston divides the fluid chamber into a rebound chamber and a compression chamber. A piston rod couples to the main piston for moving the main piston between a compression stroke and a rebound stroke. The sleeve is in an abutment relationship with the second section of the main tube, radially spaced apart from the first section of the main tube, defining a compartment extending between the sleeve and the first section of the main tube. A housing for the damper assembly is also disclosed herein.

摘要： A damper assembly for a suspension system of an associated vehicle. The damper assembly comprises a cylindrical tube extending along an axis and defining a chamber. A piston is located in the chamber and is moveable along the axis in a compression direction and a rebound direction. The piston includes a piston rod extending from a first end to a piston head. A rebound stop is located on the piston rod between the first end and the piston head. A hydraulic rebound stop (“HRS”) piston is located in a HRS chamber. A rebound spring biasing the HRS piston towards the adaptor plate in the HRS chamber. The piston rod is slideably received within the HRS piston in the rebound direction until the rebound stop contacts the rebound head and causes the rebound spring to compress.
