Abstract

An automatic transmission comprises: a double clutch comprising a first clutch and a second clutch, a first input shaft connected to the first clutch, a second input shaft connected to the second clutch through the first input shaft, and an output shaft. The automatic transmission also comprises a synchronizer, a one-way clutch, and a gear reduction mechanism including a first gear set and a second gear set. The first gear set comprises a first gear and a second gear meshed with each other, and the second gear set comprises a third gear and a fourth gear meshed with each other. The third gear is fixed on the second input shaft through the one-way clutch, and the synchronizer is fixed on the second input shaft. The automatic transmission and a vehicle including the automatic transmission are characterized in that the one-way clutch is disposed between the third gear and the second input shaft to prevent power from being transmitted to the second input shaft from the output shaft through the second gear set. Furthermore, wear of the double clutch is effectively reduced, and the service life of the double clutch is increased.

Description

technical field [0001] The invention relates to an automatic transmission and a vehicle including the automatic transmission. Background technique [0002] At present, with the rapid development of vehicle manipulation automation, automotive transmissions are showing a trend of vigorous development. The current automotive automatic transmissions mainly include hydraulic transmissions (AT), continuously variable transmissions (CVT) and electromechanical transmissions (AMT) with high transmission efficiency. [0003] AMT, which is superior to AT and CVT in terms of transmission efficiency and production cost, has been valued by the automotive industry because of its advantages of high fuel economy, low emissions and protection of existing manual transmission production investment required by the development of the automotive industry. [0004] However, during the use of AMT, its shortcomings were gradually discovered: when the vehicle is shifting gears, when the clutch is dis...
