ADJUSTABLE MAGNETORHEOLOGICAL SHOCK-ABSORBER Russian patent published in 1996 - IPC

FIELD: mechanical engineering. SUBSTANCE: shock-absorber has housing with a cylindrical chamber filled with a magnetic liquid, hollow rod mounted inside the chamber, piston made up as a core, pole cogs engaged with different core poles that are directed toward each other, mounted with a spaced relation and form a system of alternative poles, and magnetically insulated washers with grooves mounted from the end faces of the pole cogs. The grooves face the spaces between the pole cogs. One of the grooves is in communication with the hollow rod. Antifriction linings are interposed between facing surfaces of the magnetically insulated washers to enclose the pole cogs. A solenoid is mounted on the core. EFFECT: enhanced shock-absorbing. 2 cl, dwg
