Drive disk for torque-transmission coupling connection between crankshaft and transmission assembly, has ring body welded in area of circular gap and/or with disk body by gap, where gap tapers in profile to contact zones

摘要

The disk has a disk body (2) and a ring body (3) welded on the disk body. The ring body axially lies at the disk body over circular contact zones (10, 11). The ring body and the disk body are formed and/or arranged such that a circular gap (13) limits radially outside at the contact zones, where the circular gap tapers in a profile to the contact zones. The ring body is welded in an area of the gap and/or with the disk body by the gap. The ring body is welded with the disk body using laser welding process and without additional welding material.
