HERSTELLUNGSVERFAHREN FÜR KUPPLUNG FÜR AUTOMATIKGETRIEBE UND AUTOMATIKGETRIEBE

摘要

In a clutch manufacturing method, inner peripheral portions of drum members 13, 23 of two clutches are connected to a sleeve member 110, and a piston 14, a seal plate 112 and a return spring 17 are provided between the drum members 13, 23, an insulator 112b to apply electric isolation between the piston and the drum member 13 or between the seal plate and another drum member 23 is attached to either the piston or the seal plate. Then, the drum member 13, to which the electric isolation with the insulator is not applied, is connected to the sleeve member. Then, the piston, return spring and seal plate are assembled to the sleeve member to which the drum member has been connected. Finally, the drum member 23, to which the electric isolation with the insulator has been applied, is connected to the sleeve member with electric welding.
