A drive device for a motor vehicle, comprising:
- a combustion engine machine, a first electric machine and a second electric machine, wherein a drive shaft of the combustion engine machine can be coupled by a first clutch to a drive shaft of the first electric machine, which is connected via a transmission device to a drive shaft of the drive device, wherein the second electric machine is permanently coupled to the drive shaft and the transmission device is provided with a planetary gear that is permanently coupled to the drive shaft of the first electric machine, wherein the planetary gear can be coupled by a second clutch to the drive shaft of the internal combustion machine, wherein the drive shaft of the first electric machine can be coupled via a third clutch to a ring wheel of the planetary gear, and wherein the planetary gear is arranged in the axial direction relative to the axis of rotation of the drive shafts between the internal combustion machine and the first electric machine, and the second electric machine.
Method for operating a drive device, comprising:
- an internal combustion engine, with a first electric machine and with a second electric machine, wherein a drive shaft of the internal combustion machine can be coupled by a first clutch to the first drive shaft of the first electric machine, which is connected via a transmission device to a drive shaft of the drive device, wherein the second electric machine is permanently coupled to the drive shaft and the drive device is provided with a planetary gear of the first electric machine that is permanently coupled to the drive shaft, wherein the planetary gear can be coupled by a second clutch to the drive shaft of the internal combustion machine, wherein the drive shaft of the first electric machine can be coupled via a third clutch to a ring wheel of the planetary gear, and wherein the planetary gear is arranged in the axial direction relative to a rotational axis of the drive shafts between the internal combustion machine and the first electric machine and the second electric machine.
