Abstract: A hybrid drive system for a motor vehicle includes a housing and an input shaft, which is provided to introduce torsional moments, which can be provided by an internal combustion engine, into the hybrid drive system, and which is rotatably mounted around a rotational axis. The system also includes an output shaft arranged coaxially in relation to the input shaft, an electric motor having a stator and a rotor, and a rotor support, which is non-rotationally connected to the rotor. The rotor support has a support hub, a support wall, and a support cylinder. The system also includes a separating clutch having a first inner disc carrier and a first outer disc carrier. A first bearing is arranged between the support hub and the housing. A second bearing is arranged between the support hub and the input shaft. The support wall and the support cylinder are a one-piece sheet metal part.

Abstract: A hybrid drive system for a motor vehicle includes an input shaft, which introduces torques from an internal combustion engine into the hybrid drive system and which is mounted rotatably around an axis of rotation. An output shaft is arranged coaxially to the input shaft. The system also includes an electric machine having a stator and a rotor, and a hub non-rotatably connected to the rotor. The system further includes a wet clutch which has a first actuating piston. The hub is formed as a one-piece forged part and has a first running surface for the first actuating piston. The wet clutch is provided to non-rotatably connect the hub to the output shaft.

Abstract: A hybrid drive train for a motor vehicle having an internal combustion engine, an electric machine, a first clutch, which is provided for coupling a crankshaft of the internal combustion engine to the rotor, and a second further clutch, which is designed as a wet clutch and which has a clutch cover. A screw connection is provided for non-rotatably connecting the rotor to the clutch cover, which screw connection includes a screw, which is substantially arranged in an axial direction and which at least partially penetrates a connecting piece non-rotatably fastened to the clutch cover.

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.

Abstract: A drive train device for a motor vehicle is disclosed. The drive train device has at least one component which is included for the purpose of transmitting a torque, and at least one cast-in element which is partially cast into the component, which is included for the purpose of transmitting the torque, where the component and the cast-in element are made of different materials. The drive train device has a sealing device which is included for the purpose of sealing a junction between the component and the cast-in element.
