Abstract

The present invention relates to a single planetary gear multi-mode hybrid power transmission for respectively connecting an engine, single or double number of motors, the single planetary gear multi-mode hybrid power transmission comprises a single planetary row, a gear shift element, a one-way clutch or a common brake, and a common gear, the single planetary row comprises a sun gear, a planetarygear, an outer gear ring and a planetary frame, wherein the planetary gear is meshed with the outer gear ring and the sun gear respectively; the single planetary row has two freedom of rotation, andcan be used to determine the rotation speed of each component; the common gear is meshed with the single planetary row; the gear shift element comprises a meshing component and a synchronous component, wherein the meshing component is connected to the common gear, and the synchronous component is connected to the drive shaft of a motor; the one-way clutch or the common brake is connected to an engine and the outer gear ring gear respectively. Compared with the prior art, the single planetary gear multi-mode hybrid power transmission has the advantages of longer service life, low mechanical complexity, low cost, low control difficulty, more smooth gear shift and the like.

Description

technical field [0001] The invention relates to the driving field of electromechanical hybrid vehicles, in particular to a single planetary gear multi-mode hybrid transmission. Background technique [0002] Electromechanical hybrid vehicles typically involve the use of an internal combustion engine and one or more electric motor / generators. Existing hybrid transmission schemes can basically be divided into two categories: hybrid schemes composed of one or two electric motors added to traditional transmissions and hybrid schemes specially designed for From the point of view of the existing development trend, the transmission scheme mainly includes the hybrid transmission scheme with series-parallel connection as the main driving mode and the power split hybrid transmission scheme with planetary row as the main drive mode. The hybrid transmission scheme with series-parallel connection as the main driving mode is relatively simple in structure, low in research and development ...
