METHOD OF MANUFACTURING CLUTCH COMPONENT

摘要

Clutch components for automotive use usually include a pair of clutch member s with operative faces. In particular, planar one way clutches include a pair of clutch members whose operative faces are enclosed spaced opposition, with each clut ch face including a plurality of recessed defining respective load bearing shoulders . A plurality of struts are disposed between the coupling face of the members, and such strut s are moveable between the coupling position and non coupling position. A preferab le method of manufacturing such clutch components includes powder metal operations comprising die compacting a metal powder into a metal blank, placing the die compacted metal blank in a machined flat ceramic support, sintering the metal blank to form a sintered metal blank, and cooling the sintered metal blank to form a cooled metal blank. Th e preferred metallic structure of the cooled metal blank is 50-80% martensite and 20-50% bainite and fine pearlite. The cooled metal blank is then measured for flatness, roundne ss or perpendicular structure in a measuring devise having supports and probes. Signals from the probes are analyzed to determine whether the parameters of concern are within tolerance.
