MAGNETIC-RHEOLOGICAL CLUTCH WITH MULTILAYER STRIPS Russian patent published in 2009 - IPC F16D37/02 

FIELD: machine building.

SUBSTANCE: invention relates to magnetic-rheological clutch. Magnetic-rheological clutch consists of stationary part, rotating initial part with initial strips and secondary part with secondary strips. Between the primary and secondary parts it is formed working space containing magnetic-rheological liquid. Primary and secondary strips are implemented as alternating one by one in radial direction. Between pairs of primary and secondary strips there are located first yokes with magnetic coils winding axis of which are directed by radius and which are located one by one circumferentially and allow opposite polarity. The first yokes allows cylindrical end surfaces from which there are proceed or in which there are introduced magnetic lines in radial direction. The primary and secondary strips are closed cylindrical envelopes. Radially to external and radially to internal first yokes it is provided external and internal the second yoke. Herewith magnetic lines of field are introduced into the second yokes and radially proceeded from them in opposite direction.

EFFECT: reduction of homogenizing annealing of field magnetic lines, maximization of its active part and for providing of closed lines of magnetic induction field.
