The coaxial multi-gear front-drive hybrid power system comprises an engine, a generator, a driving motor, a gear speed change mechanism, a clutch and a differential mechanism, the clutch is arranged between an output shaft of the engine and the gear speed change mechanism, an output shaft of the gear speed change mechanism is connected with the differential mechanism, and the generator is electrically connected with the driving motor. A motor output shaft of the driving motor is of a hollow shaft structure, and an output shaft of the differential mechanism penetrates through the motor output shaft and then is connected with wheels. The system has four modes of pure electric drive, direct drive, series connection and parallel connection, the mechanical transmission efficiency is high, the wet clutch adopted by the system is good in gear shifting smoothness, the shafting arrangement is of a four-shafting structure, the arrangement position of the wet clutch and the arrangement position of a synchronizer are staggered, the size is small, a planetary gear is omitted, the cost is low, and the technical difficulty is small.

    本发明公开了一种同轴式多挡位前驱混合动力系统,包括发动机、发电机、驱动电机、齿轮变速机构、离合器和差速器,离合器设置在发动机输出轴和齿轮变速机构之间,齿轮变速机构的输出轴连接差速器,发电机和驱动电机电连接,驱动电机的电机输出轴构造为空心轴结构,差速器的输出轴穿过电机输出轴后与车轮相连,还包括增速齿轮副。本发明具备纯电驱动、直驱、串联、并联四种模式、机械传动效率高,系统采用的湿式离合器换挡平顺性好,轴系布置为四轴系结构且湿式离合器布置位置与同步器布置位置错开,使得体积小、取消了行星齿轮,成本低技术难度小。
