Problems solved by technology
At present, the existing 7-speed DCT transmission has a relatively small range of speed ratios under the premise of ensuring dynamic performance. At the same time, due to structural limitations, the speed ratio range is relatively large, resulting in severe shifting shocks and reducing driving comfort.
The high-end transmission is limited to the space limit in the front compartment of the engine, and it is generally a longitudinal transmission, which is driven by the rear drive, and the transmission efficiency is low
Therefore, the transmission in the prior art has problems such as low transmission efficiency, large speed ratio and low driving comfort.

The invention provides a transmission, a power assembly and a vehicle, and relates to the field of vehicle power. The transmission comprises an eighth gear mechanism, and the eighth gear mechanism comprises an eighth driving gear, an eighth driven gear, an eighth shaft and an eighth synchronizer. The eighth shaft is arranged in parallel with a first input shaft. The eighth driving gear and the eighth driven gear are arranged on the eighth shaft, the eighth driving gear is meshed with a first driving gear on a second input shaft, and the eighth driven gear is meshed with a second driving gear on the first input shaft. The eighth synchronizer is used for realizing combination or separation of the eighth driving gear and the eighth shaft. According to the scheme, the eighth shaft and the eighth gear are increased, and the transmission efficiency can be improved on the premise of not increasing the length of the transmission.
Description
technical field [0001] The invention relates to the field of vehicle power, in particular to a transmission, a power assembly and a vehicle. Background technique [0002] Most wet dual-clutch transmissions at this stage adopt the traditional three-shaft design, that is, an input shaft assembly composed of two input shafts and two output shaft assemblies. The parking position is generally arranged on one of the two output shafts, or placed on the differential. The power transmission route is that the C1 clutch and the C2 clutch connect the engine with the input 1 shaft and the input 2 shaft respectively, and the input 2 shaft is vacantly sleeved on the input 1 shaft, so that all gears of the transmission can be operated under the condition of engine torque input, and in odd numbers When the gear is in the gear, the pre-engagement of the even number can be realized, and vice versa, so as to test the uninterrupted transmission of power. At present, the existing 7-speed DCT tr...
