Abstract
A transmission clutch housing for transmitting a rotational motion from a driving shaft to a driven shaft in conjunction with a clutch plate assembly is formed from a single piece of metal. The housing includes a central web structure extending axially from an axis of rotation, a splined clutch-plate-engaging flange extending axially From the central web structure, and a rotational member coupling flange, which may be in the form of a pulley or a gear, also extending axially from the central web structure. In the method of forming the transmission clutch housing, a flat metal blank is placed on a spin forging device. A peripheral edge of the blank is split in a radial direction by a splitting tool to form two split portions. The two split portions are then spin formed into the splined clutch-plate-engaging flange and the rotational member coupling flange.
