Abstract

The invention provides a nine-gear dual-clutch transmission and a vehicle. The nine-gear double-clutch transmission comprises a second main reduction gear, a differential gear ring, a differential, a fourth-gear driven gear, an eighth-gear driven gear, a third-gear driven gear, a seventh-gear driven gear, a reverse gear idle gear, a second output shaft, a sixth / eighth-gear driving gear, a third-gear driving gear, an inner input shaft, a fifth / seventh-gear driving gear, a reverse gear driving gear, a first output shaft, a reverse gear driven gear, a fifth-gear driven gear, a transition gear, a sixth-gear driven gear, a second-gear driven gear, a first main reduction gear, a second-gear driving gear, a fourth-gear driving gear, a second clutch, a first clutch, an outer input shaft and a synchronizing device. According to the nine-gear dual-clutch transmission, the overall length of the dual-clutch transmission is greatly shortened, and the nine-gear dual-clutch transmission can be applied to the vehicle with a front transverse front drive.

Description

technical field [0001] The invention belongs to the technical field of vehicle transmissions, in particular to a nine-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 rotatably nested inner and outer input shafts are respectively connected to one of the clutches, and the two input shafts are respectively Transmitting the power of two transmission speed groups, the shifting procedure is completed by automatically switching between the two clutches, so the continuity of power during the shifting process can be realized, that is, the power is not interrupted during the shifting process, which overcomes AMT Disadvantages of shifting shock. 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 of the vehicle...
