发明名称 Verfahren zur Herstellung eines Kupplungsgehäuses
摘要 A torque transmitting structure for an automatic transmission has an inner hub for rotating the structure and an outer annular shell. The annular shell has an internal radial spline portion (26), an external brake surface, a torque tube and an axially facing drive connecting surface. The annular shell is manufactured in a flow forming process, wherein a cup-shaped blank (18) is secured on a mandrel (10) which has a shape complementary to the internal shape of the shell. Forming rolls (14) engage the outer surface and are moved axially relative to the mandrel in a manner to form the desired outer contour of the shell. After the flow forming operation, the shell is removed from the mandrel, the axial drive connection is formed by metal removal and the hub is bonded to the shell. <IMAGE>
