Abstract

A hybrid drive system for a motor vehicle has an input shaft which is rotatably mounted around an axis of rotation, via which torques provided by an internal combustion machine can be introduced into the hybrid drive system, an output drive shaft arranged coaxially with the input shaft, an electric machine which has a stator and a rotor, and a torque converter which has an impeller, a converter cover connected to the impeller, an interior for receiving oil, and a converter hub which is connected to the converter cover. The converter hub is connected to the rotor in a manner fixed against rotation. The system further has a separable clutch having a disc pack, a clutch chamber in which the disc pack is received, an operating piston, and an associated operating chamber. Via the separable clutch the converter hub can be connected to the input shaft fixed against rotation.
