Abstract

Provided is a dual clutch transmission. First and second input shafts are mounted concentrically. First and second output shafts are mounted in parallel to the first input shaft and respectively include output gears engaged with a ring gear of a differential. The rotations of first and second gears are restrained by the first input shaft. The rotations of third and fourth gears are restrained by the second input shaft. The rotations of fifth and sixth gears engaged with the second and third gears, respectively, are restrained by the first output shaft. The rotation of a seventh gear engaged with the first gear is restrained by the second output shaft. An eighth gear is engaged with the second gear to be rotatable about the second output shaft. The rotation of a ninth gear engaged with the fourth gear and restrained by the eighth gear is restrained by the second output shaft.
