Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a dual-motor powertrain based on an AMT gearbox. Background technique [0002] With the rapid development of my country's economic construction and the continuous improvement of people's living standards, the number of automobiles in our country is also increasing, which brings huge pressure on our resources and environment. As an important chemical raw material - petroleum, more than half of it is used as fuel for motor vehicles. Therefore, the development of energy-saving vehicles and the use of alternative energy sources are the main ways to alleviate the current energy pressure. [0003] The use of pure electric energy as new energy vehicles has become the mainstream trend. However, the existing electric vehicles are only equipped with a power motor. When the output end of the power motor is connected to the AMT gearbox, the electric vehicle The power interruptio...
