Problems solved by technology

[0003] At present, most of the existing 8-speed and above multi-speed dual-clutch transmissions adopt the current general-purpose 7-speed and below parallel shaft transmission system structure arrangement. However, the more the number of gears, the more new parts will be added, and the volume of the transmission will be corresponding. increase, the required installation space also becomes larger

Abstract

The invention discloses a dual-clutch automatic transmission and a vehicle, and the dual-clutch automatic transmission comprises a first clutch, a second clutch, a first input shaft, a second input shaft, a first output shaft, a second output shaft, a third output shaft and a first synchronizing device, wherein the first input shaft is connected with a power source through the first clutch; the second input shaft is connected with the power source through the second clutch and is sleeved outside the first input shaft in an empty mode; the first input shaft is fixedly sleeved with an odd-number-gear driving gear; the second input shaft is fixedly sleeved with an even-gear driving gear; the first output shaft and the second output shaft are sleeved with all-gear driven gears in an idling mode; the third output shaft is fixedly sleeved with a parking ratchet wheel and is hollowly sleeved with a reverse driven gear; and the first synchronizing device is used for controlling the driven gears to be combined with and separated from the output shafts where the driven gears are located. According to the technical scheme, the structural compactness of the double-clutch automatic transmission can be improved.

Description

technical field [0001] The invention relates to the technical field of vehicle transmission, in particular to a dual-clutch automatic transmission and a vehicle. Background technique [0002] The transmission is one of the main components in the vehicle transmission system, which can change the driving speed of the vehicle and the torque of the driving wheels in a wide range. Due to its high transmission efficiency and short power interruption time for shifting, dual-clutch transmissions are gradually increasing their market share in the application market of automatic transmissions for passenger cars, and are gradually developing in the direction of more gears. [0003] At present, most of the existing 8-speed and above multi-speed dual-clutch transmissions adopt the current general-purpose 7-speed and below parallel shaft transmission system structure arrangement. However, the more the number of gears, the more new parts will be added, and the volume of the transmission wi...
