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.
