Dual clutch transmission apparatus

摘要

A dual clutch transmission apparatus includes: a first input shaft (15); a second input shaft (16) arranged in parallel with the first input shaft; a counter shaft (17) arranged in parallel with the first input shaft; a connecting clutch (35) adapted to establish or interrupt a transmitting path of rotation of the first input shaft to the output shaft; and a low/high shift stage switching mechanism (30) having a low-speed shift stage gear train (31a, 31b) and a high-speed shift stage gear train (32a, 32b), and a low/high shift stage switching clutch (33) switching the low-speed shift stage gear train and the high-speed shift stage gear train and changing a rotational speed of the counter shaft to a high or low rotational speed. Either the connecting clutch or the low/high shift stage switching mechanism is selected.
