Abstract:
A magneto-rheological damping device comprising:a core element capable of acting as a magnetic circuit which carries a magnetic flux; a rigid case element surrounding a portion of the core element and a passage existing between the case element and core element; an amount of magneto-rheological fluid positioned between the core element and case element to flow within the passage; a magnetic flux generator positioned adjacent a portion of the core element and 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 comprising a plurality of stacked laminations, the laminations forming a series of individual magnetic poles with gaps therebetween, the magnetic flux generator operable to generate a magnetic flux in the poles and case element and across the gaps to affect the fluid flow in the passage.
