摘要

The auxiliary drive by electric motors has crankcase (3) at the flange (6,18) along connecting area connected to the several joints (12,20). The deformed material section (11) is fastened to recess (10,19) which helps in caulking of joints. At connection area the thickness of the recess is smaller than the wall thickness of crankcase. An independent claim is also included for auxiliary drive.
