A drive device for a motor vehicle, comprising:
- a first drive assembly, a second drive assembly, and an epicyclic gear train coupled to the second drive assembly, wherein the second drive assembly is coupled to a driven shaft of the drive device via the epicyclic gear train and is removably coupled to the first drive assembly by a shift clutch, and a secondary drive shaft of at least one secondary drive of the drive device is coupled to the epicyclic gear train;
- wherein the first drive assembly is removably coupled to a change gear transmission via another shift clutch, wherein an output shaft of the change gear transmission is coupled to the driven shaft or formed as the driven shaft.
A method for operating a drive device for a motor vehicle, the drive device comprising:
- a first drive assembly, a second drive assembly, and an epicyclic gear train that is coupled to the second drive assembly, wherein the second drive assembly is coupled to a driven shaft of the drive device via the epicyclic gear train and is removably coupled to the first drive assembly by a shift clutch, wherein a secondary drive shaft is coupled to the epicyclic gear train;
- wherein the first drive assembly is removably coupled to a change gear transmission via another shift clutch, wherein an output shaft of the change gear transmission is coupled to the driven shaft or formed as the driven shaft;
- wherein the method comprises:
- starting the second drive assembly;
- and
- starting the first drive assembly using the second drive assembly.
