FLEXPLATES AND METHOD FOR CAPACITOR DISCHARGE WELDING OF FLEXPLATES

摘要

A two-piece flexplate assembly having a ring gear welded to a central plate using a capacitor discharge welding process. The weld is established between a joining structure defined between the ring gear and the central plate using either an overlap arrangement, a projection arrangement, or a chamfer arrangement.
