Abstract
A gearbox (G) for a motor vehicle having a drive shaft (GW); an output shaft (GW); an electric machine (EM); and first and second minus planetary gear sets (P,P), the first planetary gear set (P) being a stepped planetary gear set. A ring gear (E) of the first planetary gear set (P) is rotationally fixedly immobilizable via a fourth shift element (). The first sun gear (E) of the first planetary gear set (P) is rotationally fixedly immobilizable via a fifth shift element (). The output shaft (GW) is connected to the ring gear (E) of the second planetary gear set (P). A rotor (R) of the electric machine (EM) is continuously connected to the drive shaft (GW). The first sun gear (E) of the first planetary gear set (P) is not continuously rotationally fixedly connected to or operatively connectable by the shift elements with any further electric machine.
