The multi-speed transmission comprises four planetary gear sets eight rotatable shafts and six shifting elements. The sun gear of the first planetary gear set is connected to the fifth shaft, which is attachable to the housing through a third brake. The input shaft is, through a first coupling, connectable to the seventh shaft connected to the sun gear of the third planetary gear set, which is connected to the bar of the first planetary gear set and is connectable to the fourth shaft through a third coupling, which is connected to the sun gear of the second planetary gear set and is attachable to the housing through a second brake. The input shaft is, through a second coupling, connectable to the eighth shaft connected to the sun gear of the fourth planetary gear set and the third shaft is connected to the ring gear of the first planetary gear set, the bar of the second planetary gear set, and the ring gear of the fourth planetary gear set, and is attachable to the housing through a first brake. The sixth shaft is connected to the ring gear of the second planetary gear set and the ring gear of the third planetary gear set. The output shaft is connected to the bar of the third planetary gear set and the bar of the fourth planetary gear set. |
