ABSTRACT:
Power train for a motor vehicle, having an engine with a driven shaft which has a crankshaft axle which is located longitudinally to the direction of travel and which is connected to a starting unit, a preliminary gear stage with an input shaft and an output shaft, the input shaft of the preliminary gear stage being connected to the starting unit and the output shaft of the preliminary gear stage having a lateral offset to the crankshaft axle, a variator which is preferably made as a disk variator with two adjustable disk sets for the continuous transmission of torque, and for which the input-side disk set is connected to the output shaft of the preliminary gear stage, while the output-side disk set is located laterally offset, a subsequent gear stage which has an input shaft and an output shaft and which is located on the same side of the variator as the preliminary gear stage, the input shaft of the subsequent gear stage being connected to the output-side disk set of the variator, and a first differential with a lateral driven shaft which is located transversely to the direction of travel and between the engine and the starting unit, and forms a first drive axle, the first differential being connected to the output shaft of the subsequent gear stage.
