Abstract:
A transmission includes a drive shaft, an output shaft, a housing, a first planetary gear set, a second planetary gear set and a third planetary gear set, as well as six shift elements, comprising a first brake, a second brake, a first clutch, a second clutch, a third clutch and a fourth clutch. Each planetary gear set features a sun gear, a planetary gear, a planetary carrier and a ring gear. The drive shaft and the output shaft are arranged in a manner axially offset to each other and the drive shaft is connectable to the ring gear of the third planetary gear set and the second brake through the first clutch. The ring gear of the third planetary gear set and the second brake are also connected to each other. A third shaft is arranged coaxially to the drive shaft.
