Abstract:
1. A dual clutch transmission apparatus, comprising: a first input shaft; a second input shaft arranged coaxially with the first input shaft and freely rotatable; a first counter shaft arranged in parallel with the first and the second input shafts; a second counter shaft arranged in parallel with the first and second input shafts; a dual clutch including a first clutch and a second clutch, the first clutch transmitting rotational torque from a power source to the first input shaft and the second clutch transmitting the rotational torque from the power source to the second input shaft; a first gear change mechanism provided between the first and the second input shafts and the first counter shaft; a second gear change mechanism provided between the first and the second input shafts and the second counter shaft; an output shaft connected to the first and the second counter shafts for transmitting the rotational torque from the power source to a driving wheel; wherein the output shaft is connected to the first input shaft via a first reduction gear train and to the second input shaft via a second reduction gear; the first gear change mechanism including a first gear switching unit and a second gear switching unit; the second gear change mechanism including a third gear switching unit; the first gear switching unit including a 1st shift stage gear train, a 3rd shift stage gear train and a first switching clutch; the second gear switching unit including a 2nd shift stage gear train, a 4th shift stage gear train and a second switching clutch; and the third gear switching unit including a 6th shift gear train, a reverse shift gear train and a third switching clutch.
