Abstract
A drive device has the following components: a connecting device that can be connected to an electric power supply, the connecting device being connected to a power converter; a first drive aggregate in the form of an electrical drive motor which is connected to the power converter; a second drive aggregate in the form of an internal combustion engine; a generator connected to the internal combustion engine and through the power converter to the electric drive motor; and various auxiliary aggregates. The generator is continuously mechanically connected to the respective auxiliary aggregates while the internal combustion engine is optionally connectable to the auxiliary aggregates as well as to the generator. In a first mode of operation, upon operation of the electric drive motor through the external electric power supply, the generator is separated from the internal combustion engine and the generator, supplied by the power supply, is operated as an electric motor and drives the auxiliary aggregates. In a second mode of operation, upon operation of the electric motor through the internal combustion engine, the internal combustion engine is designed in such a way that it drives the…
