  • Publication number: 20210131541
    Abstract: A hybrid drive module for a motor vehicle having an input shaft, an electric machine with a stator fixed with respect to relative rotation and a rotatable rotor, a disconnect clutch in the power flow between the input shaft and the rotor, and a torque converter with a lockup clutch, the housing of the torque converter being connected to the rotor so as to be fixed with respect to rotation relative to it. The disconnect clutch is actuatable in closing direction by pressurization of a first pressure space. The lockup clutch is actuatable in closing direction through pressurization of a second pressure space. The two pressure spaces are defined at least partially by the housing of the torque converter. The housing of the torque converter separates the first pressure space directly from the second pressure space.
