ABSTRACT:
A friction disc for use in multiplate friction wet clutch packs in automatic transmissions for vehicles or other friction clutch applications wherein an annular core plate is segmented with interlocking end portions to form a ring, and the friction facings are also segmented and are bonded to the core plate with the facing segments overlapping the interlocking ends of the core plate segments. Also, the ends of the friction facing segments may be interlocked or slightly spaced apart to form oil channels therebetween, and openings may be formed in the core pieces to intersect circumferentially offset radial channels opening into opposite edges of the friction segment to form oil passages into the disc.
