Abstract

The invention discloses a dual-power-drive automatic transmission, comprising: an engine; an engine input shaft assembly including an engine input shaft connected to the engine; an output shaft assembly including an output shaft and an output gear sleeving the output shaft; a driving motor shift shaft assembly including a driving motor shift shaft and a first reduction gear sleeving the same; a driving motor input shaft assembly including a driving motor input shaft and a second reduction gear sleeving the same, wherein the second reduction gear is in meshing fit with the first reduction gear; a driving motor, wherein a motor output shaft the driving motor is connected to the driving motor input shaft, and one or both of the driving motor shift shaft and the engine input shaft can selectively drive the output shaft through a transmission device; a differential connected with the output gear. By using dual power sources in the transmission, the problem that a mechanical automatic transmission experiences torque or power interruption during gear shifting is solved.

Description

technical field [0001] The invention relates to a hybrid power system for automobiles, in particular to a dual power drive automatic transmission. Background technique [0002] For 2020 / 2025 fuel consumption indicators, the United States, Europe, Japan and China have formulated fuel consumption (or CO 2 ) emission requirements, and the implementation of China's 2020 / 2025 fuel consumption regulations, make the hybrid system an indispensable solution. [0003] Among them, in the current automatic transmission, the engine and the drive motor are used to provide power. However, it is difficult to match and adjust the speed ratio, and it is not easy to make the engine work in the high-efficiency zone. There are problems of torque and power interruption during the shifting process. . [0004] Therefore, how to overcome the defects existing in the existing automatic transmission is a technical problem that those skilled in the art need to solve at present. Contents of the inven...
