Title:
ELECTROMAGNETIC CLUTCH DEVICE
Document Type and Number:
Japanese Patent JP2016056861
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an electromagnetic clutch device capable of improving an effect of reducing a dragging torque.SOLUTION: An electromagnetic clutch device 1 comprises a housing 2; a clutch part 3 capable of engaging or disengaging a shaft 10 arranged to be rotatable in respect to the housing 2 and the housing 2; and electromagnetic coil 4 for generating electromagnetic force acting the clutch part 3. The clutch part 3 includes a plurality of outer clutch plates 31 connected to the housing 2 in a relative non-rotatable manner, an inner clutch plate 32 arranged between the plurality of outer clutch plates 31, a disc spring 34 made of resilient material for spacing-apart the outer clutch plates 31. The inner clutch plate 32 is made flat while being held between a plurality of outer clutch plates 31 and has a resiliency where its contact area with the outer clutch plates 31 is increased.SELECTED DRAWING: Figure 2
