Abstract

The present invention relates to a single planetary gear hybrid power transmission system which comprises a single planetary row, wherein the single planetary row comprises three rotatable parts, namely, an outer gear ring, a sun gear and a planetary gear respectively meshed with the outer gear ring and the sun gear, and the planetary gear is connected to a planetary frame; a power supply, whereinthe power supply comprises an engine, a first motor and a second motor respectively connected to the single planetary row in a transmission manner, and a power storage battery for charging and powerutilization is mounted on the first motor and the second motor; a gear shift component, wherein the gear shift component comprises a gear shift element and a single-phase clutch or a brake for lockingthe transmission of the engine and the single planetary row; and an output shaft, wherein the output shaft is connected to the single planetary row in a transmission manner, and a main reducer is mounted on the output shaft. Compared with the prior art, the invention has the advantages of low mechanical complexity, low control difficulty, multiple modes and so on.

Description

technical field [0001] The invention relates to the driving field of electric hybrid vehicles, in particular to a single planetary gear hybrid transmission system. 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 costs, and ge...
