ABSTRACT:
An electromagnetic clutch assembly of the leaf spring type has leaf springs the inner ends of which are fixed to a drive plate by conventional rivets, and the outer ends of which are fixed to the armature plate by special rivets having enlarged diameter shanks that extend through clearance holes in overlaying portions of the drive plate. Rubber damper rings are trapped beneath an enlarged head of the rivet, against the outer surface of the driver plate, without intruding into the radial clearance. The clearance holes allow the rubber rings to compress freely as the leaf springs flex when the clutch is activated. During operation, the transmission of torsional vibrations back through the drive plate and springs to the armature plate is dampened by the compressed rubber rings.
