The invention discloses a ten-speed double-clutch type automatic transmission and a vehicle. The ten-speed double-clutch type automatic transmission comprises two output shafts, a reverse gear shaft and two input shafts connected to an engine through clutches. Among the gears from the second gear to the ninth gear, the driving gears of the four odd gears are arranged on the first input shaft, andthe driving gears of the four even gears are arranged on the second input shaft; a second-gear driven gear, a sixth-gear driven gear, a fifth-gear driven gear and a third-gear driven gear are sequentially arranged on the first output shaft, an eighth-gear driven gear, a fourth-gear driven gear, a seventh-gear driven gear and a ninth-gear driven gear are sequentially arranged on the second output shaft, and a reverse-gear driven gear connected to the second-gear driven gear is arranged on the reverse-gear shaft; and six synchronizers are arranged on the two output shafts and the reverse gear shaft, power of the driven gears of the corresponding gears is output to the corresponding shafts through the five synchronizers, and the driven gears of the fifth gear and the sixth gear are connectedthrough one synchronizer and used for achieving the first gear. The transmission is small in axial size and provided with ten forward gears, so that the engine has more probabilities to work in the optimal area, the dynamic property and economy of the whole vehicle are obviously improved, and oil consumption is reduced.
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 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 longer produ...
