Description

technical field [0001] The invention relates to the technical field of automobile transmission transmission, in particular to a double-motor planetary gear transmission. Background technique [0002] In the 21st century, the Chinese government has put forward an industrial development policy to encourage the development of small-displacement energy-saving vehicles, and pure electric vehicles are an important means to achieve this goal. The current pure electric vehicle transmission system usually uses a single motor, the power will be interrupted when shifting gears, and the shifting efficiency is low. Due to the single-motor system, it is difficult for the motor to run in the high-efficiency zone all the time, which easily causes waste of electric energy. [0003] For example, the Chinese invention patent document with the application number 201010188764.X discloses an arrangement structure of a gearbox gear shaft system, including an input shaft, a first output shaft para...
