Abstract

The present invention provides a multi-speed dual-clutch transmission and a vehicle. The multi-speed dual-clutch transmission includes coaxially nested outer input shafts and inner input shafts. Seventh, ninth and third gears are fixed on the outer input shafts. 4th, 6th, 8th and 2nd gear driving gears are fixed on the inner input shaft; the first outer output shaft and the first inner output shaft are coaxially nested, and the first inner output shaft has a 9th gear driven gear. The second outer output shaft and the second inner output shaft are coaxially nested, and the second inner output shaft is emptied with a seventh-speed driven gear. The third gear, the fourth gear and the eighth gear driven gear are set on the second outer output shaft; the synchronous device controls the driven gear of each gear and its shaft, the first outer output shaft, the first inner output shaft and the second outer output shaft and Engagement and disengagement of the second inner output shaft. The multi-speed dual-clutch transmission reduces the reaction time for shifting gears.

Description

technical field [0001] The invention belongs to the technical field of vehicle transmissions, in particular to a multi-speed dual-clutch transmission and a vehicle. Background technique [0002] The dual-clutch automatic transmission integrates two gearboxes and two clutches in one transmission housing, and two inner and outer input shafts that are rotatably nested together are respectively connected with one of the clutches, and the two input shafts transmit two transmissions respectively. The power of each gearbox speed group completes the shift program by automatically switching between the two clutches, so the continuity of power during the shift process can be realized, that is, the power is not interrupted during the shift process, which overcomes the AMT shift Disadvantages of impact: During the shifting process of the vehicle, 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 ...
