Problems solved by technology

Most of the existing hybrid vehicles are in the form of series and parallel structures, which have few working modes and low transmission efficiency.
There is also a hybrid transmission system that combines a planetary gear mechanism with a CVT, but the transmitted torque is small and cannot bear a large load, and it is limited when it needs to transmit large power

Abstract

The invention discloses a five-gear automatic transmission-based hybrid vehicle transmission system, which comprises an internal-combustion engine, a hydraulic torque converter, a main motor, a regulating motor, a first planet row, a first clutch, a second clutch, a spur gear A, a spur gear B, a spur gear C, a spur gear D, a spur gear E, an inverter, a storage battery, a differential mechanism and a five-gear automatic transmission gear structure. Power dividing is realized by utilizing the power dividing characteristics of the planet gears; when two paths of power are transmitted, the spur gears are used to improve the transmission efficiency; the main motor is used for realizing electric drive; and the engine load optimization or auxiliary drive is realized by changing the operating mode of the regulating motor. The integrated design of the system is compact, and the system is particularly suitable for front-engine vehicles; and the adopted five-gear automatic transmission gear structure has the advantages of simple shifting logic, a few shifting elements, high transmission efficiency and the like; and by various operating modes, the system can meet requirements of various working conditions.

Description

technical field [0001] The invention relates to the field of a hybrid electric vehicle, in particular to a transmission system of a hybrid electric vehicle based on a five-speed automatic transmission. Background technique [0002] At present, the transmission system of hybrid electric vehicles is generally a combination of oil and electricity. According to the position of the engine and the motor, different transmission system structures can be formed, such as series, parallel, hybrid and plug-in. Most of the existing hybrid electric vehicles are in the form of series and parallel structures, which have few working modes and low transmission efficiency. There is also a hybrid transmission system that combines a planetary gear mechanism with a CVT, but the transmitted torque is small, it cannot bear a large load, and it is limited when it needs to transmit a large power. Contents of the invention [0003] The present invention proposes a hybrid electric vehicle transmissi...
