    摘要： A damper includes a piston that carries a relatively compact control valve for controlling fluid flow through the piston. The control valve provides a variable amount of damping by regulating damper fluid flow between the extension chamber and the compression chamber of the damper during extension and compression strokes. Pressure regulation across the piston is controlled through two alternate flow paths as determined by the control valve. Damping through the first flow path is relatively soft and is determined according to the deflective characteristics of first and second single bi-directional annular disc valves in parallel. Damping through the second flow path is relatively firm and is determined solely by the second bi-directional single annular disc.

    摘要： A novel and improved magnetorheological fluid damper is provided which effectively secures a flux ring to a piston core in a manner which prevents relative axial and radial movement between the flux ring and the core throughout operation while minimizing the size of the piston assembly yet providing effective damping. Several connector devices are disclosed for both axially and radially securing the flux ring relative to the piston core at one end of the piston assembly in a simple manner without increasing the length of the piston assembly. The connector device may include an outer portion brazed to the flux ring, an inner portion connected to the piston core, bridge portions extending between the outer and inner portions, flow passages formed between the bridge portions and an inlet cavity formed adjacent an annular flow gap to permit unimpeded, enhanced laminar flow through the flow gap by improving the damping effect. Other connector devices may include elongated rivets extending through the flow gap axially along the piston assembly, and elongated pin and spacer tube connectors extending radially between the piston core and the flux ring. Various embodiments of radial support devices are disclosed for possible use in combination with the connector devices to enhance radial support by, for example, the use of balls, a washer with tabs, a coil bobbin with tabs, rivets and axially extending elongated pins.

    摘要： A monotube damper and suspension spring assembly for a motor vehicle includes a tubular housing defining a chamber filled with damping fluid. A piston and piston rod reciprocate within the chamber. In order to compensate for volumetric changes of the chamber due to extension and retraction of the piston rod within the chamber, either the upper seal cover or lower bottom ring assembly is slidable within the housing. A preload is applied either to the housing or to the seal cover to thereby bias these elements to compensate for volumetric changes in the chamber.

    摘要： An improved magnetorheological fluid damper is provided which effectively provides a smooth transition, without a sharp break in the damper force/velocity curve, between very low damping forces near zero damper velocity to higher damping forces at higher piston velocities while maintaining desirable maximum force levels. The damper includes a piston assembly, including a magnet assembly and a flow gap extending through the piston assembly to permit fluid flow between the chambers. The force/velocity optimization feature includes a groove or passage open to the flow gap, positioned in series with a part of the flow gap in a magnetic circuit generated by the magnet assembly and dimnensioned/sized to permit fluid flowing through the passage to experience a magnetorheological effect less than a magnetorheological effect experienced by fluid flowing through the flow gap but not through the groove. Preferably, the passage is formed in an inner annular surface of a flux ring positioned around a piston core. The passage may be formed, for example, by a curvilinear surface, a modified rectangular surface or a triangular surface.

    摘要： A snap ring closure system is particularly useful in securing a rod guide in an end of a tube of a hydraulic damper. The snap ring closure system utilizes an end cap or rod guide having a double-lobed groove and a peripheral flange about its outer end. The double-lobed groove includes an outer lobe and an inner lobe of a lesser depth than the outer lobe. A groove is formed on the tube and is positioned to design with the doubled-lobed groove when the end cap is inserted in the tube. The end cap includes a first snap ring in the outer lobe which expands outwardly into the tube groove when the cap is first inserted. The cap is secured by engagement of the first snap ring with the inner more shallow lobe. A second snap ring is placed between the flange and the end of the tube to remove any play between the end cap and tube.

    摘要： A damper body for a magnetorheological (MR) damper and associated methods of forming the damper body. The damper body is formed of a base material, such as a steel, and is coated with an abrasion-resistant layer comprising chromium. The layer of chromium provides a sliding wear surface for sliding contact with a reciprocating piston. To avoid high-stress abrasive wear over the expected service life of the magnetorheological damper, the layer of chromium has a minimum thickness greater than or equal to a minimum thickness of about 8 &mgr;m. In other embodiments, before applying the abrasion-resistant layer of chromium, the damper body is coated with a layer of a hard coating material having a hardness greater than the hardness of the base material. The effective hardness of the damper body is a composite of the respective hardnesses of the base material comprising the damper body and the layer of hard coating material. The thickness of abrasion-resistant layer of chromium is chosen in direct relation to the effective hardness.
