Commercial vehicle with an internal combustion engine (2), a hydrostatic variable displacement pump (3) driven by this and a hydraulic motor (5) controlled by this pump as main drive train (1), to the pressure lines (4) of which an electro-hydraulic secondary drive train (7), comprising a battery-driven electric motor (10) and a hydrostatic pump (9), is connected, it being possible to use either the main drive train alone or, after shutdown of the main drive train, the secondary drive train alone, or else both drive trains simultaneously in the event of an increased power demand. <IMAGE>
