Description
technical field [0001] The invention relates to a gearbox, in particular to an electric vehicle automatic gearbox. Background technique [0002] Automobiles are an indispensable means of transportation for human beings. However, with the aggravation of environmental pollution and the continuous reduction of non-renewable resources, people are more and more interested in the development and research of electric vehicles. The gearbox is an important part of an electric vehicle. The traditional gearbox is shifted by a manual shift fork, which is cumbersome to operate and easy to stall when shifting gears. The structure of the gearbox is complex and difficult to install, which cannot satisfy people's smooth driving of electric vehicles. . Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an electric vehicle automatic transmission that can automatically change gears. [0004] In order to solve the above-mentioned tech...
