Abstract
A twin-clutch-type transmission, which has a general input shaft, a first clutch connected with a first clutch output shaft, a second clutch connected with a second clutch output shaft, a sub shaft, and a general output shaft disposed parallel to the first clutch output shaft and the second clutch output shaft, is improved to effectively use the space around the sub shaft. A first gear connected to the first clutch output shaft and a second gear connected to the sub shaft associatingly interlock the sub shaft and the first clutch output shaft while being meshed to each other. A fifth gear and a sixth gear disposed on the general output shaft are respectively meshed with the third gear and the fourth gear which are connected to the second clutch output shaft and selectively connected to the general output shaft with a first synchronizing device disposed on the general output shaft, and interlock the second clutch output shaft and the general output shaft in association with the third gear and the fourth gear. A seventh gear meshed with the fifth gear and a eighth gear meshed with the fourth gear disposed on the sub shaft interlock the sub shaft and the general output shaft by selectively connecting the seventh gear and the eighth gear themselves to the sub shaft by the second synchronizing device so as to complete the first forward speed gearing in addition to completing the reverse gearing.
