Abstract

The invention provides a dual-clutch transmission, which is mainly used in electric vehicles and hybrid vehicles. The transmission can provide four forward gears, which mainly solves the problem that electric vehicles with only a single-stage reduction ratio cannot take into account driving force and speed. The transmission includes a planetary gear row, a planetary gear row input shaft, a gear selection assembly, a first input shaft, a second input shaft, a first clutch, a second clutch, etc. The two input shafts are respectively connected to two clutches, and the first input shaft The shaft transmits motion and torque with the input shaft of the planetary gear row through gears (or sprockets). The gear selection component connects different parts of the planetary gear row with the input shaft of the planetary gear row to obtain multiple reduction ratios. The second input shaft Motion and torque are transmitted through the gears (or sprockets) and the planet carrier of the planetary gear row.

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...
