The individual superposition gears and the continuously variable transmission are coupled to each other via one respective connecting gear. The second shaft of the first superposition gear and a shaft of the second superposition gear can be alternatively joined to the gear output via a shiftable clutch. The second shaft of the first superposition gear can be connected in a torsion-proof manner to the third shaft of the second superposition gear. The first shaft of the second superposition gear is joined to a shaft of the first superposition gear via another shifting clutch.
