Abstract
A gear structure layout of a double clutch transmission includes a main input shaft for receiving an engine torque. A first and second input shaft rotating coaxially with the main input shaft. A first and second clutch, first and third drive gears formed on an input shaft, and second and fourth drive gears formed on the other input shaft. A first output device for selectively changing torques of the first, second, third, and fourth drive gears and for outputting the changed torque. A second output device for selectively changing torques of the first, second, third, and fourth drive gears and for outputting the changed torque. Also included is a differential gear commonly connected to the first output device and the second output device. The layout provides for only four drive gears on input shafts that enables a total of seven speeds, and a compact double clutch transmission.
