The invention provides an eight-speed double-clutch type automatic transmission and a vehicle. The eight-speed double-clutch type automatic transmission comprises two output shafts and two input shafts connected to an engine through clutches correspondingly. A third-gear driving gear, a fifth-gear driving gear and a seventh-gear driving gear are arranged on a first input shaft, a second-gear driving gear, a fourth-gear driving gear, a sixth-gear driving gear and an eighth-gear driving gear are arranged on a second input shaft, a second-gear driven gear, a fifth-gear driven gear and a sixth-gear driven gear are arranged on a first output shaft, and a third-gear driven gear, a fourth-gear driven gear, a seventh-gear driven gear and the eighth-gear driven gear are arranged on a second outputshaft. The second-gear driven gear and the sixth-gear driven gear are connected with the first output shaft through a first synchronizer, the fifth-gear driven gear is connected with the first outputshaft and the sixth-gear driven gear through a second synchronizer and a third synchronizer correspondingly, the fourth-gear driven gear and the eighth-gear driven gear are connected with the second output shaft through a fourth synchronizer, and the third-gear driven gear and the seventh-gear driven gear are connected with the second output shaft through a fifth synchronizer. A first-gear gear isreduced, two sleeved input shafts are adopted to arrange the driving gears with seven forward gears, a fifth gear, a sixth gear and a second gear are combined to achieve the first gear, the axial size is short, and the power performance and economical efficiency of the whole vehicle are improved.
Description
technical field [0001] The invention belongs to the field of new energy vehicles, in particular to an eight-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 gears, 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 lon...
