Abstract

The invention discloses a dual-two-gear dual-motor hybrid power system which comprises an engine, a first motor and a second motor, wherein a first motor shaft of the first motor is connected with an output shaft of the engine through a transmission mechanism, and the transmission mechanism comprises a first clutch; a first gear shifting mechanism is arranged between the output shaft of the engine and an automobile driving shaft and comprises a transmission shaft, a second clutch, a third clutch and a differential mechanism arranged on an automobile output shaft; and a second motor shaft of the second motor is connected with the automobile driving shaft through a second gear shifting mechanism, and the second speed change mechanism comprises a single-row planet mechanism and a synchronizer. The four functions of engine two-gear driving, motor two-gear switching driving, generator decoupling and driving motor decoupling can be achieved. The power acceleration performance of high and low vehicle speeds can be better covered, and meanwhile, the economical efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of hybrid vehicle power system transmission, and specifically relates to a double-two-gear dual-motor hybrid system that realizes two-gear driving of an engine and switching drive between two gears of a motor. Background technique [0002] In order to effectively reduce vehicle fuel consumption and exhaust emissions, and meet the requirements of the double credit policy, more and more automakers are promoting and developing hybrid vehicles. Hybrid electric vehicles use batteries or engines to generate power to provide power sources for motors, and adjust the operating point of engines through motors, which can effectively reduce fuel consumption and emissions, and further improve vehicle power and economy. Different hybrid system configuration schemes can realize different torque distribution functions. In terms of configuration scheme, a hybrid electric vehicle can adopt a single-motor power system configu...
