Abstract:
A multi-speed transmission for a motor vehicle includes a housing, a drive shaft, an output shaft, and at least four planetary gear sets, whereas each of the planetary gear sets comprises one sun gear, at least one planet, one planetary carrier and one ring gear. Several shift elements are provided in the form of at least four clutches and at least two brakes. The drive shaft is connectable through the third clutch to the first brake and to the sun gear of the first planetary gear set and to the sun gear of the second planetary gear set. The ring gear of the first planetary gear set is connected to the planetary carrier of the fourth planetary gear set. The planetary carrier of the fourth planetary gear set is connectable through the fourth clutch to the drive shaft. The sun gear of the fourth planetary gear set is connected to the housing. The second brake is connected to the planetary carrier of the first planetary gear set.
