摘要： A suspension damper assembly capable of adjusting the height of an automobile includes a cylinder tube defining a pumping chamber aligned concentrically within a reservoir tube. A fluid reservoir is defined between the reservoir tube and the cylinder tube. A piston is slideably disposed within the cylinder tube. A gas cup is slideably disposed within the assembly and separates a fluid chamber within the cylinder tube from a gas chamber. The gas cup includes a cup conduit connecting the pumping chamber to the reservoir chamber whereby stroking the gas cup pumps fluid into the pumping chamber increasing the outward force of the piston for raising the height of the vehicle. A piston shaft guide includes a shaft valve allowing fluid to pass from the pumping chamber to the reservoir chamber for reducing the outward force of the piston and lowering the height of the vehicle.

摘要： The subject inventive steering damper assembly includes a rotor sleeve having open first and second ends and a drive plate disposed in the open second end. A core is co-axially disposed in the rotor sleeve closing the open first end of the rotor sleeve and defining a magnetic fluid chamber with the sleeve. A Magneto-Rheological fluid is disposed in the magnetic fluid chamber. The drive plate is flexible to provide manufacturing and operational tolerance, and is securely attached to the open second end of the rotor sleeve. Flexibility is derived from at least one aperture disposed in the drive plate. The aperture may be formed in a variety of shapes including elongated, round and oval shaped apertures.

摘要： A rotary damper for use in motor vehicle suspensions comprising a rotor disposed within damping fluid in a fluid chamber of a casing to form inner fluid volume and outer fluid volume, with first valve and second valve for controlling flow between the inner fluid volume and the outer fluid volume, and an accumulator using closed cell foam as a compressible material for fluid fill variation and thermal expansion. First valve controls flow from the outer fluid volume to the inner fluid volume for one direction of rotation of the rotor, while second valve controls flow from the inner fluid volume to the outer fluid volume for the opposite rotation of the rotor. Thus, the valves are configured to provide independent control of damping for each direction of rotation. A valve holder supporting the valves and providing flow passages is designed for powdered metallurgy fabrication.

摘要： A seatbelt retractor is operably coupled to a belt dereeling retarder mechanism which utilizes a magnetorheological fluid and a coil for imposing a magnetic field on the fluid to selectively change the fluid properties and a braking or retarding effect imposed on the belt retractor during dereeling or payout of the belt. The retarder may include a piston coupled to a rotatable shaft coupled to the belt retractor reel and displacing fluid through the magnetic field in response to actuation of the belt. Alternate embodiments include a multiple disc brake coupled to the retractor reel through a gear drive speed increaser or a cylindrical housing and core member defining an annular space occupied by the magnetorheological fluid and connected to the belt retractor reel through a speed increasing gear drive.

摘要： A damper for a vehicle rack and pinion-type power steering system reduces or eliminates high frequency and low amplitude vibrations commonly associated with high-speed steering wheel shake. The damper includes a hydraulically actuated clutch that is energized by a spring in the damper. The damper locks or inhibits rotation of a steering shaft coupled to the rack and pinion assembly while the vehicle is traveling straight down the road to absorb the input energy and cancel any vibration from the wheels, suspension or road. The clutch is released when there is any steering wheel input from the operator. Increased pressure from the power steering pump as a result of steering wheel input increases the pressure in the damper to compress a spring and release the multi-disk clutch. This allows the steering system to behave in an acceptable manner by not adding any friction or extra force requirements to the driver and providing acceptable feel and return to center characteristics for the steering system.

摘要： A vehicle steering system includes a steering wheel and a steering shaft coupled between the steering wheel and wheels of the vehicle. The shaft is operable for rotating when the steering wheel is turned to thereby turn the vehicle wheels. A vibration damping system for absorbing vibrations in the steering wheel and shaft includes a rotor coupled to the steering shaft to rotate with the shaft and a case surrounding the rotor and a clutch surface proximate the rotor. A magnetic circuit generates a magnetic flux in the rotor. The rotor is operable to engage the clutch surface and thereby vibrationally couple the steering shaft to the case to absorb vibrations in the shaft, and when a magnetic flux is generated therein, to disengage the clutch surface so that the steering shaft may more freely rotate.

摘要： A magneto-rheological damping device comprises a core element capable of acting as a magnetic circuit which carries a magnetic flux, and a case element surrounding a portion of the core element. A passage exists between the case element and core element, and an amount of magneto-rheological fluid is positioned between the core element and case element to flow within the passage. A magnetic flux generator is positioned adjacent a portion of the core element and is operable to generate a magnetic flux which acts upon the magneto-rheological fluid in the passage to affect the flow of fluid in the passage. The core element comprises a plurality of stacked laminations, which form a series of individual magnetic poles with gaps therebetween. The magnetic flux generator is operable to generate a magnetic flux in the poles and case element and across the gaps to affect the fluid flow in the passage.
