Abstract: A drive system includes a hydrodynamic coupling device having a housing assembly, which is to be connected to an input shaft for rotating therewith, and an output element, which is to be brought into drive connection with a transmission arrangement. The hydrodynamic coupling device also comprises an electric machine equipped with a rotor assembly, which is connected to the housing assembly for rotating therewith, and with a stator assembly, wherein the stator assembly is supported on a housing that surrounds the hydrodynamic coupling device at least in areas. The area of the housing which supports the stator assembly has a cooling medium channel arrangement.

Abstract: An adjustment device for automatically operating a vehicle transmission, includes an actuator to operate a gear input part that, depending upon a desired gear, assumes a position corresponding to that gear. An emergency operating device is connected to the actuator for activating a tension element to establish an active connection to the gear input part for the purpose of setting a position of the gear input part corresponding to a selected gear during a failure of the actuator.
