Electromagnetic granule type clutch

Abstract

Abstract PURPOSE:To increase the cooling effect of the electromagnetic granule type clutch by a method wherein a bearing support, closing an annular cylinder for the electromagnetic granule type clutch, is formed with a communicating hole. CONSTITUTION:The annular cylinder 32, accommodating a solenoid coil 33 therein, is secured detachably to the side part of a flywheel 31. A bearing 38 is located previously on the bearing support 37 while the bearing 38 is fitted with a hub 40a integral with a rotor 40. Above-described bearing support 37 is secured to the annular cylinder 32 to complete the electromagnetic grain type clutch. A multitude of the communicating holes 37e, communicating the inside and outside of the annular cylinder 32, are formed on the outer peripheral side of the bearing support 37, which is nearer to the hub 40a. The clutch effect may be carried out by exciting electromagnetic granules existing between the rotor 40 and the annular cylinder 32 while the cooling effect may be increased by the communicating holes 37e.
