Multi-gear double-clutch transmission and vehicle

Abstract

The invention provides a multi-gear double-clutch transmission and a vehicle. The multi-gear double-clutch transmission comprises an outer input shaft, an inner input shaft, a first outer output shaft, a first inner output shaft, a second outer output shaft, a second inner output shaft and a synchronization device, wherein the inner input shaft is coaxially embedded in the outer input shaft, a seventh-gear driving gear, a ninth-gear driving gear and a third-gear driving gear are fixed to the outer input shaft, and a fourth-gear driving gear, a sixth-gear driving gear, an eighth-gear driving gear and a second-gear driving gear are fixed to the inner input shaft; the first inner output shaft is coaxially embedded in the first outer output shaft, the first inner output shaft is sleeved with a ninth-gear driven gear in an idling manner, and the first outer output shaft is sleeved with a second-gear driven gear and a sixth-gear driven gear in an idling manner; the second inner output shaft is coaxially embedded in the second outer output shaft, the second inner output shaft is sleeved with a seventh-gear driven gear in an idling manner and the second outer output shaft is sleeved with a third-gear driven gear, a fourth-gear driven gear and an eighth-gear driven gear in an idling manner; and the synchronization device is used for controlling all the driven gears to be combined with and separated from the shafts of the driven gears, the first outer output shaft to be combined with and separated from the first inner output shaft and the second outer output shaft to be combined with and separated from the second inner output shaft. By the adoption of the multi-gear double-clutch transmission, the gear shifting response time is shortened.

Description

technical field [0001] The invention belongs to the technical field of vehicle transmissions, in particular to a multi-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 inner and outer input shafts that are rotatably nested together are respectively connected with one of the clutches, and the two input shafts transmit two transmissions respectively. The power of each gearbox speed group completes the shift program by automatically switching between the two clutches, so the continuity of power during the shift process can be realized, that is, the power is not interrupted during the shift process, which overcomes the AMT shift Disadvantages of impact: 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 ...
