ELECTRICALLY CONTROLLED MAGNETIC-DISPERSED BRAKE AND LOADER FOR EXERCISERS WITH ELECTRICALLY CONTROLLED MAGNETIC-DISPERSED BRAKE Russian patent published in 1999 - IPC

FIELD: sportive equipment. SUBSTANCE: brake has magnetic core casing with conducting coil and brake disks, nonmagnetic rotor mounted inside casing and equipped with magnetic core loading disks with concentric projections on their surfaces. Magnetic flux concentrators on inner surfaces of casing and on brake disks are formed as concentric projections arranged in opposed relation to loading disk projections. Space between projections is filled with magnetorheological suspension. Exerciser loader with electrically controlled magnetic-dispersed brake has shell with rotor and working member. Loader has shaft carrying free-wheel clutch and cylindrical drum, which are enclosed within casing fixed on brake shell. Loader shaft is rigidly joined with brake rotor. Cylindrical drum is mounted for free rotation on free-wheel clutch. Spiral spring is disposed in cylindrical drum. Deflecting drum is mounted in rotating bracket on cylindrical drum casing. Deflecting channel is disposed on console pivotally fixed on deflecting roller spindle offset relative to bracket pin. Working member is formed as flexible cable coiled on cylindrical drum, fixed with its end on drum surface and passed through bracket pin, deflecting roller and deflecting channel. Such construction allows idle stroke loads to be minimized and exercising to be performed with minimum repositioning of loaders. EFFECT: increased efficiency, simplified construction and enhanced reliability in operation. 5 cl, 7 dwg
