Abstract

A drive train device for a motor vehicle is disclosed. The drive train device has a first component, a second component which is connected to the first component so as to transmit torque and consists at least substantially of a material formed from lightweight metal, and at least one element which is at least partially enclosed in the second component and which consists at least substantially of a predominantly iron-containing material. The enclosed element is a connecting element which is connected to the first component by substance-to-substance bonding in order to produce the torque-transmitting connection. The first component and/or the second component at least partially form a housing. The enclosed element projects axially on both sides out of the material of the second component and at least one side of the enclosed element which projects axially has at least one balancing element and/or at least one balancing recess.
