Abstract

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.

Description

technical field [0001] The invention relates to a transmission mechanical device, in particular to a magneto-rheological fluid clutch. Background technique [0002] At present, liquid viscous transmission, as an emerging technology, has attracted more and more attention. Liquid viscous transmission is generally divided into cylindrical oil film, disc oil film, conical oil film and combined oil film according to the shape of the mechanism of the shearing effect of the oil film. Due to the presence of viscous liquid between the active and passive parts, the liquid viscous transmission is characterized in engineering applications: the active and passive parts are non-rigid and flexible transmission, which can realize stepless speed regulation, and the speed regulation process is soft and stable, and the time is short , high sensitivity, high precision; stable speed regulation, easy to realize remote control and automatic control; the prime mover can be started under light load...
