Abstract:
1. A transmission, comprising: a transmission input shaft; a transmission output shaft; a main gear set; a main gear set comprising a first planetary gear set an a second planetary gear set and, in order of speed, a first shaft, a second shaft, a third shaft, and a fourth shaft; a first power transmission path between the transmission input shaft and the main gear set, comprising a first fixed transmission ratio; and a second power transmission path between the transmission input shaft and the main gear set, comprising a second fixed transmission ratio lower than the first fixed transmission ratio; wherein at least one of the first shaft, the second shaft, the third shaft and the fourth shaft is capable of being connected to an electric machine, wherein the first shaft is capable of being connected via a first shifting element to the first power transmission path and via a second shifting element to the second power transmission path, wherein the second shaft is capable of being connected via a third shifting element to the first power transmission path and via a fourth shifting element to the second power transmission path, wherein the third shaft is continuously connected to the transmission output shaft, wherein the fourth shaft is capable of being fixed via a sixth shifting element and is capable of being connected via a fifth shifting element to the first power transmission path or the second power transmission path.
