Abstract

The invention provides a dual-clutch transmission mainly used for an electric vehicle and a hybrid electric vehicle. The transmission can provide four forward gears, so that the problem that the driving force and speed of an electric vehicle only having a single-stage speed reducing ratio can not be simultaneously considered is mainly solved. The transmission comprises a planetary gear row, gear selecting assemblies, a first input shaft, a second input shaft, a first clutch, a second clutch, an output shaft and the like; the two input shafts are respectively connected with the two clutches; the gear selecting assemblies are used for connecting different parts of the planetary gear row with the input shafts to obtain a speed reducing ratio of a plurality of speed ratios; and movement and a torque are output from a planetary carrier to the output shaft by a gear (or a chain wheel) or are output from the second input shaft to the output shaft by 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...
