Abstract:
A magnetorheological damper, comprising:a cylinder containing a magnetorheological fluid;a piston and magnet assembly mounted for reciprocal movement in said cylinder to form a first chamber positioned on one side of said piston and magnet assembly and a second chamber positioned on an opposite side of said piston and magnet assembly, said piston and magnet assembly adapted to generate a magnetic field and including a piston core and a flux ring positioned around said piston core to form a flow gap sized to permit magnetorheological fluid flowing through said flow gap to experience a magnetorheological effect affecting the flow of the magnetorheological fluid through said flow gap, said piston and magnet assembly further including a first end plate positioned at one end of said piston assembly, at least one of said flux ring and said first end plate including a first crimp portion connecting said flux ring to said first end plate.
