Patent ID: 7066043

Claim:
A double clutch transmission comprising: a main input shaft for receiving an engine torque; a first input shaft rotating coaxially with the main input shaft; a second input shaft rotating coaxially with the main input shaft and along an exterior circumference of the first input shaft; first and second clutches for selectively transmitting a torque of the main input shaft to the first and second input shafts; first and third drive gears formed on one input shaft among the first and second input shafts; second and fourth drive gears formed on another input shaft among the first and second input shafts, said another input shaft being different from said one 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; and a differential gear commonly connected to the first output device and the second output device.
