ABSTRACT:
An improved structure for a clutch brake is disclosed. Powdered metal, such as powdered steel, is initially pressed into a preform having a desired configuration for each of a pair of opposed covers for the clutch brake. The configuration of the outer surface of each of the preforms includes a plurality of embossed segments, which alternate with non-raised areas, arranged in an annular array. The embossed segments of the covers are the portions thereof which are frictionally engaged during use. Each of the segments is defined by inner and outer circumferentially extending sides connected by a pair of generally radially extending ends. The intermediate portions of both of the ends can be curved circumferentially inwardly toward one another to form a concave region. The covers together form an internal cavity in which inner and outer brake washers are disposed. A wave washer is also disposed within the cavity and includes a plurality of waves which abut against an internal surface of the cover only opposite the non-raised areas.
