1. A hybrid drive system for a motor vehicle, the hybrid drive system comprising:
a housing;
an input shaft, which is configured to introduce torsional moments provided by an internal combustion engine into the hybrid drive system, wherein the input shaft is rotatably mounted around a rotational axis;
an output shaft arranged coaxially in relation to the input shaft;
an electric motor having a stator and a rotor;
a rotor support, which is non-rotationally connected to the rotor, wherein the rotor support has a support hub, a support wall, and a support cylinder;
a separating clutch having a first inner disc carrier and a first outer disc carrier;
a first bearing arranged between the support hub and the housing, wherein the first bearing is arranged to rotatably mount the support hub in relation to the housing;
a second bearing arranged between the support hub and the input shaft, wherein the second bearing is arranged to rotatably mount the support hub in relation to the input shaft, wherein the support wall and the support cylinder are a one-piece sheet metal part, wherein the first inner disc carrier is non-rotationally connected to the input shaft, and the first outer disc carrier is non-rotationally connected to the rotor support;
a third bearing; and
a torsional moment converter having a pump wheel, a converter cover non-rotationally connected to the pump wheel, and a converter hub non-rotationally connected to the converter cover, wherein the third bearing is arranged between the input shaft and the converter hub and rotatably mounts the converter hub in relation to the input shaft.
