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.
