Transmission and vehicle provided with same

Abstract

The invention discloses a transmission and a vehicle provided with the transmission. The transmission comprises a double clutch, a first input shaft, a second input shaft, a first output shaft, a second output shaft, a first-fifth gear synchronizer, a second-fourth gear synchronizer, a third-seventh gear synchronizer, a sixth gear synchronizer and a reverse gear synchronizer. The double clutch comprises a first clutch plate and a second clutch plate, the first input shaft is connected with the first clutch plate, the first input shaft is fixedly provided with a first-gear driving gear, a third-gear driving gear and a fifth-seventh-gear driving gear, the second input shaft is connected with the second clutch plate, the second input shaft is fixedly provided with a second-gear driving gear and a fourth-sixth-gear driving gear, the first output shaft is sleeved with a first-gear driven gear, a fifth-gear driven gear, a second-gear driven gear and a fourth-gear driven gear, the second output shaft is sleeved with a third-gear driven gear, a seventh-gear driven gear, a sixth-gear driven gear and a reverse-gear gear which is meshed with the second-gear driven gear, and the reverse gear synchronizer is used for connecting the reverse-gear gear with the third-gear driven gear or the seventh-gear driven gear. According to the transmission disclosed by the invention, the number of driving gears can be reduced, and accordingly the volume of the transmission is reduced.

Description

technical field [0001] The invention relates to the technical field of automobile construction, in particular to a transmission and a vehicle with the transmission. Background technique [0002] The transmission efficiency of the traditional automatic transmission is relatively low, and the existing DCT has a long axial dimension due to the large number of driving gears, and at the same time, there are few gears. The power and economy matching the vehicle are not ideal, and some DCT transmissions It is necessary to increase the reverse gear shaft to realize the reverse gear function, which further increases the volume of the DCT transmission, and also leads to high cost, difficult layout, and poor bearing capacity. Contents of the invention [0003] The present invention aims to solve one of the above-mentioned technical problems in the prior art at least to a certain extent. [0004] Therefore, an object of the present invention is to provide a transmission that can redu...
