Abstract

The invention provides a multi-gear dual clutch transmission and a vehicle. The multi-gear dual clutch transmission comprises an external input shaft, an internal input shaft, a first external output shaft, a first internal output shaft, a second external output shaft, a second internal output shaft and a synchronizing device. A tenth-gear driving gear, an eighth-gear driving gear and a fourth-gear driving gear are fixed to the external input shaft. A third-gear driving gear, a fifth-gear driving gear, a seventh-gear driving gear and a first-gear driving gear are fixed to the internal input shaft. The first internal output shaft is sleeved with a tenth-gear driven gear in a spaced mode. The first external output shaft is sleeved with a fifth-gear driven gear and a first-gear driven gear in a spaced mode. The second internal output shaft is sleeved with an eighth-gear driven gear in a spaced mode. The second external output shaft is sleeved with a fourth-gear driven gear, a third-gear driven gear and a seventh-gear driven gear in a spaced mode. The synchronizing device is used for controlling the combination and separation between all the driven gears and the shafts where the driven gears are located, between the first external output shaft and the first internal output shaft as well as between the second external output shaft and the second internal output shaft. By the adoption of the multi-gear dual clutch transmission, the response time of gear shifting is shortened.

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 ...
