Abstract

The invention provides a double-clutch transmission which is mainly used for electric automobiles and hybrid electric vehicles. The double-clutch transmission can provide four advancing gears, and the problem that an electric automobile only with a single-stage reduction ratio cannot take the driving force and the speed into consideration is mainly solved. The double-clutch transmission comprises a planetary gear row, an input shaft of the planetary gear row, gear selecting assemblies, a first input shaft, a second input shaft, a first clutch, a second clutch and the like, wherein the two input shafts are connected with the two clutches correspondingly, the first input shaft transmits the motion and torque to the input shaft of the planetary gear row through a gear (or a chain wheel), and different components of the planetary gear row are connected with the input shaft of the planetary gear row through the gear selecting assemblies, so that multiple reduction ratios are obtained; and the second input shaft transmits the motion and torque to a planetary carrier of the planetary gear row through a gear (or a chain wheel).

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...
