Abstract

The invention provides a multi-speed dual-clutch transmission and a vehicle. The multi-speed dual-clutch transmission includes an outer input shaft and an inner input shaft coaxially nested, and a seventh / ninth-speed driving gear and a third-speed driving gear are fixed on the outer input shaft , the fourth-speed driving gear, the second-speed driving gear and the sixth / eighth-speed driving gear 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 nine empty sleeves. The second gear driven gear and the sixth gear driven gear are placed on the first outer output shaft; the second outer output shaft and the second inner output shaft are coaxially nested, and the second inner output shaft is emptier Seventh-speed driven gear, the third-speed driven gear, the fourth-speed driven gear and the eighth-speed driven gear are placed on the second outer output shaft; the synchronization device controls the driven gears of each gear and the shaft where it is located, and the first outer output shaft Combination and separation of the first inner output shaft and the second outer output shaft and 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 ...
