Abstract
A drive device for a hybrid-driven motor vehicle includes a primary drive, a secondary drive, and a variable speed gearbox. The primary and secondary drives are configured to drive the gearbox separately or jointly. The gearbox includes a first input shaft connectable to the primary drive, a second input shaft connectable to the secondary drive, an output shaft, and switching elements. In a first state of the gearbox, a rotational movement of a first fixed toothed wheel of a first intermediate shaft is synchronously coupled with a rotational movement of the output shaft by a first switching element. In a second state, a rotational movement of a first idler toothed wheel on the first input shaft is synchronously coupled with a rotational movement of a second idler toothed wheel on the first input shaft by a second switching element.
