Abstract:
1. 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 about 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 shaft respectively; a drive gear unit including a plurality of drive gears disposed respectively on the first and second input shafts; a first output device including a first output shaft disposed parallel to and apart from the main input shaft by a predetermined distance and having a plurality of driven gears and a first output gear thereon, such that torques of drive gears on the first and second input shafts are selectively changed and output; a second output device including a second output shaft disposed parallel to and apart from the main input shaft by a predetermined distance and having a plurality of driven gears, a second output gear, and a reverse driven gear thereon, such that torques of drive gears on the first and second input shafts are selectively changed and output; a differential gear commonly connected to the first output gear and the second output gear; and a parking gear disposed on one output shaft of the first and second output shafts in a transmission case at an axial position thereof corresponding to one drive gear engaged with one driven gear of another output shaft.
