PURPOSE: A transmission of a vehicle is provided to optimize the driving states of an engine connected to the transmission by comprising the transmission of eleven forward speeds and one reverse speed. CONSTITUTION: A first complex planetary gear device(CG1) is composed by connecting a first planetary gear device(PG1) to a second planetary gear device(PG2) with one permanent connecting route and another selective connecting route. A second complex planetary gear device(CG2) is composed by connecting a third planetary gear device(PG3) to a fourth planetary gear device(PG4) with the permanent connecting route. The second complex planetary gear device is connected to the first complex planetary gear device with at least one permanent connecting route. One route of an input shaft(IN) is directly connected to the rotation element of the first complex planetary gear device. The other two routes of the input shaft are selectively connected to the rotation elements of the first and second complex planetary gear devices. An output shaft(OUT) is connected to one rotation element of the second complex planetary gear device. A first brake(B1) and a second brake(B2) selectively fix the two different rotation elements of the first complex planetary gear device. A third brake(B3) selectively fixes the rotation element of the second complex planetary gear device. |
