Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.
