Abstract:
A magneto-rheological damping device comprising:a core element for carrying a magnetic flux; a magnetic flux generator positioned adjacent to a portion of the core element and operable to generate a magnetic flux in the core element; a sleeve positioned over the core element and magnetic flux generator, the sleeve including a plurality of protrusions extending generally radially outwardly from a center of the core element; a flux ring surrounding the core element and sleeve and defining a passage between flux ring and core element for the flow of a magneto-rheological fluid, the flux ring operable for forming a magnetic circuit and confining a portion of the magnetic flux proximate the core element and in the passage; the sleeve protrusions configured to engage the flux ring and secure the flux ring in a position around the core element and sleeve.
