Abstract

The invention provides a double-clutch transmission which is mainly applied to an electric automobile and a hybrid power vehicle. The transmission can provide four forward gears, and the problem that driving force and the speed cannot be both considered in an electric automobile with the single reduction ratio is solved. The double-clutch transmission comprises a planetary gear row, a gear selecting assembly, a first input shaft, a second input shaft, a first clutch, a second clutch and an output shaft. The two input shafts are connected with the two clutches correspondingly. An input shaft of the first clutch is connected with the second input shaft or an input shaft of the second clutch, the gear selecting assembly enables different parts of the planetary gear row to be connected with the input shafts to obtain a plurality of reduction ratios, and the reduction ratios are output to the output shaft through a planet carrier via gears or chain wheels.

Description

technical field

[0001] The invention relates to the technical field of automobile transmissions, in particular to a dual-clutch transmission. Background technique

[0002] The driving conditions of the car are complex and changeable. When accelerating rapidly or climbing a steep slope, it needs to overcome a very large acceleration resistance or climbing resistance, while the driving resistance when driving at a constant speed on a straight road is only a fraction or even a few tenths of the former. One is that the driving resistance changes greatly. In addition, modern cars need to crawl at a speed of several kilometers per hour or even lower, and also need to drive at a speed of more than 100 per hour or even higher, and the driving speed changes greatly. However, the current automotive engine technology, especially the widely used gasoline and diesel engines, can only output torque in a narrow speed range of hundreds to thousands of revolutions, which requires the automot...
