Abstract

A drive device for a motor vehicle, with a first drive assembly, a second drive assembly, and an auxiliary drive having at least one auxiliary assembly. The auxiliary drive being coupled to or can be coupled to, respectively, the first drive assembly and the second drive assembly via an epicyclic gear transmission. The auxiliary drive is coupled to a first transmission element of the epicyclic gear transmission. In this case, a second transmission element of the epicyclic gear transmission is coupled by a gearshift transmission, which is shifted in a speed-dependent manner, to a secondary drive shaft, which is coupled to or can be coupled to the first drive assembly.
