ABSTRACT:
A viscous coupling apparatus having enhanced torque progression characteristics. The viscous coupling apparatus includes two sets of viscous coupling plates which are interleaved and mounted with rotatable members for relative rotation therebetween. Each plate is a generally circular ring of thin plate material and has one or more openings formed therein. The openings include coined edge surfaces that form an inclined surface and an arcuate wiping surface. The coined edges facilitate the wiping and removal of viscous fluid from the surface of an adjacent coupling plate when relative rotation and frictional contact occurs between adjacent plates without generating excessive wear on one of the mating plates. The removal of the viscous fluid promotes enhanced frictional contact between the facing adjacent plate surfaces and results in an increased torque transmission characteristic.
