Abstract

The invention provides a hybrid power transmission system of an automobile, and belongs to the technical field of automobiles. The problem that the rotational inertia of an output shaft in an existing transmission transmission system is high is solved. The hybrid power transmission system of the automobile comprises an engine, an output shaft, four planetary gear trains, a second clutch, a motor connected with the output end of the engine and an input shaft connected with the motor. The four planetary gear trains are a second planetary gear train of which a second planet carrier is connected with the input shaft, a first planetary gear train of which a first sun gear is connected with a second sun gear of the second planetary gear train, a third planetary gear train of which a third sun gear is connected with a second outer gear ring of the second planetary gear train, and a fourth planetary gear train; a third planet carrier of the third planetary gear train is connected with a fourth planet carrier of the fourth planetary gear train through the second clutch, and the fourth planet carrier of the fourth planetary gear train is connected with the output shaft. The hybrid power transmission system of the automobile achieves the purpose of reducing the rotational inertia of the output shaft, so that the output efficiency is higher.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and relates to a hybrid power transmission system of an automobile. Background technique [0002] Along with improving constantly of people's quality of life, people are more and more higher for the utilization rate of automobile, and existing automobile has also developed the transmission of hybrid power, and existing hybrid power automatic transmission is the automatic transmission of hydraulic mode work. The hybrid hydraulic automatic transmission is composed of a motor, a hydraulic torque converter, a planetary gear train and a hydraulic control mechanism. Among them, the automatic transmission realizes automatic up-down gears through complex sets of planetary gear trains and multiple clutches. At present, , the proportion of automatic transmissions is constantly increasing. Generally, the existing brake transmissions on the market are mainly six-speed automatic transmissions, and the num...
