摘要： A dual clutch transmission which can reduce the overall length of a transmission and improve mountability in the vehicle by simplifying the constituent elements of the transmission, is configured by reducing the number of synchronizers and external gears and shafts, and a drive motor is not disposed on the same axle as other constituent elements to reduce the overall length of the transmission, reducing cost and weight of the transmission to improve mountability of the transmission in the vehicle.

摘要： A multi-stage transmission includes an input shaft, an output shaft, a first planetary gear set, a second planetary gear set, a third planetary gear set, and a fourth planetary gear set. Each planetary gear set includes three rotating elements. Six shifting elements are connected to the rotating elements of the first, the second, the third and the fourth planetary gear sets. A first rotating element of the first planetary gear set is fixedly connected to a first rotating element of the second planetary gear set and a second rotating element of the third planetary gear set and is selectively connected to the input shaft. A second rotating element thereof is fixedly connected to a third rotating element of the third planetary gear set and a third rotating element of the fourth planetary gear set. A third rotating element thereof is selectively connected to the input shaft.
