Summary: | The invention discloses to a fan clutch with magnetic rheologic fluid, comprising active plate, passive plate, magnetic rheologic fluid, drive shaft, excitation coil, bearing and sealing device. Drive shaft is connected with active plate set in hollow cavity of passive plate. Passive plate is divided into frontal and rear shell. Sealing cover, excitation coil and outer ring of clutch are set orderly from inner to outer between frontal and rear shell. Rheologic fluid is injected into the cavity formed by active and passive plate and excitation coil supplies power by carbon brush assembled at the central axis of frontal shell. Drive shaft is connected with engine and passive plate is connected with fan. The invention is a circular clutch with magnetic rheologic fluid. The structure is very compact and it is applied in narrow space between cooling fan and water tank of engine. Rheologic fluid is flowing iteratively in the space between active and passive plate, which is advantaged to eliminate heat and prolongs the service life of rheologic fluid. |
