  • Patent number: 11926219
    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.

  • Patent number: 11628716
    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.

  • Patent number: 11628717
    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.
