Abstract

The invention provides a multi-gear dual clutch transmission and a vehicle. The multi-gear dual clutch transmission comprises an outer input shaft and an inner input shaft which are coaxially nested,a first outer output shaft and a first inner output shaft which are coaxially nested, a second outer output shaft and a second inner output shaft which are coaxially nested, and a synchronizing device, wherein a plurality of driving gears are fixedly arranged on the outer input shaft and the inner input shaft; at least one driven gear meshed with the corresponding driving gear is sleeved above thefirst outer output shaft and the first inner output shaft; at least one driven gear meshed with the corresponding driving gear is sleeved above the second outer output shaft and the second inner output shaft; and the synchronizing device is used for controlling the combination and separation of all driven gears and shafts on which the driven gears are positioned, the combination and separation ofthe first outer output shaft and the first inner output shaft, and the combination and separation of the second outer output shaft and the second inner output shaft. According to the multi-gear dualclutch transmission, the transmission efficiency of the transmission is improved, and the reaction time of gear shifting is reduced.

Description

Technical field [0001] The invention belongs to the technical field of vehicle transmissions, and particularly relates 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 a transmission housing. Two rotatably sleeved inner and outer input shafts are connected to one of the clutches respectively, and the two input shafts transmit two The power of each gearbox speed group is automatically switched between the two clutches to complete the shift program, so the continuity of the power during the shift can be realized, that is, the power is not interrupted during the shift, which overcomes the AMT shift The shortcoming of the impact is that the power of the engine can always be transmitted to the wheels during the shifting process of the vehicle. The shift is fast and smooth, which not only guarantees the acceleration of the vehicle, but also because the vehicle no lo...
