The ten-speed dual-clutch automatic transmission and the vehicle of the present invention comprise two output shafts, a reverse gear shaft and two input shafts respectively connected to the engine through clutches; among the second to ninth gears: four odd-numbered gears are arranged on the first gear On the first input shaft, the driving gears of four even gears are arranged on the second input shaft; the sixth, second, fifth and seventh gear driven gears are arranged in sequence on the first output shaft, and the eighth, fourth, and seventh gears are arranged in sequence on the second output shaft. 3rd and 9th gear driven gears, the reverse gear shaft is provided with a reverse gear driven gear connected to the 2nd gear driven gear; the two output shafts and the reverse gear shaft are provided with six synchronizers, through five synchronizers Correspondingly, the power of the driven gears of each gear is output to the corresponding shaft, and the driven gears of the third and fourth gears are engaged through a synchronizer to realize the first and tenth gears. The axial dimension is short and there are more gears, so that the engine has more chances to work in its optimum area, which obviously improves the power and economy of the whole vehicle and reduces fuel consumption.
Description
technical field [0001] The invention belongs to the field of transmissions, in particular to a ten-speed dual-clutch automatic transmission and a vehicle. Background technique [0002] The dual-clutch automatic transmission integrates two gearboxes and two clutches into one transmission. Two rotatably sleeved input shafts are respectively connected to one of the clutches, and the two input shafts transmit two transmissions respectively. The power of the gearbox speed group completes the shift program by automatically switching between the two clutches, so the power shift during the shift process can be realized, that is, the power is not interrupted during the shift process, which overcomes the AMT (Automated Mechanical Transmission, electric In the process of shifting, the power of the engine can always be transmitted to the wheels, and the shifting is fast and smooth, which not only ensures the acceleration of the vehicle, but also because the vehicle no longer generates s...
