MAGNETO-RHEOLOGICAL DAMPING SYSTEM FOR PREVENTING STRATIFICATION

摘要

A magneto-rheological (MR) damping system for preventing stratification of MR fluid is disclosed. The MR damping system has a housing, a piston, and a stir band. The piston operably reciprocates within the housing and includes a circumferential portion. The circumferential portion has a groove. The stir band is disposed in the groove of the piston and includes an outer periphery and a plurality of flexible protrusions. The flexible protrusions have a head portion and a tail portion. The head portion is fixed to the outer periphery. The tail portion extends from the head portion and is disjointed from the outer periphery and is substantially flexible relative to the head portion. Therefore, the stir band diverts a flow of MR fluid in one of a clockwise or a counter-clockwise direction about the circumferential portion of the piston, during a reciprocatory movement of the piston.

1. A magneto-rheological (MR) damping system for preventing stratification of MR fluid, the MR damping system comprising:
a housing; a piston structured and arranged to operably reciprocate within the housing, the piston including a circumferential portion, the circumferential portion having a groove therein; a stir band disposed in the groove of the piston, the stir band including:
an outer periphery;a plurality of flexible protrusions including:
a head portion fixedly attached to the outer periphery of the stir band; anda tail portion extending from the head portion, disjointed from the outer periphery of the stir band and being substantially flexible relative to the head portion, thereby diverting a flow of MR fluid in one of a clockwise or counter-clockwise direction about the circumferential portion of the piston, during a reciprocatory movement of the piston.
