ELECTROMAGNETIC TWO-WAY CLUTCH

摘要

PROBLEM TO BE SOLVED: To reinforce the attraction force by an electromagnetic force in an electromagnetic two-way clutch. SOLUTION: An inner shaft, an intermediate shaft, and an outer shaft are arranged from the rotary shaft center. An inside electromagnetic clutch unit is assembled between the inner shaft and the intermediate shaft, and an outside electromagnetic clutch is assembled between the intermediate shaft and the outer shaft. The outside unit is so engaged that an armature 207 is attracted to a rotor 302 by the electromagnetic force. The inside unit is so engaged that an armature 107 is attracted to a diametrical side face 210 by the electromagnetic force. The rotor 302 and the diametrical side face 210 are provided with inner/outer two slits and the armatures 207 and 107 are provided with slits in positions sandwiched between the slits. The operation of the slits forms a magnetic circuit in a form of reciprocating two elements to become the attraction targets twice so as to reinforce the attraction force.
