The invention relates to a multi-working-mode parallel hybrid power system which is characterized in that a second clutch device (13) is arranged in a motor speed change module, and a third clutch device (14) is arranged between the output end of an engine speed change module and the output end of a motor input gear pair; switching of different working modes of the hybrid power system is achieved through on-off switching of the second clutch device (13) and the third clutch device (14). The motor and the engine can independently shift gears, and power transmission is kept continuous and uninterrupted in the gear shifting process; the pure electric driving capability is improved, and the starting torque is increased; an engine independent driving mode and a motor independent driving mode are respectively arranged, so that the driving efficiency is higher under a high-speed working condition; power complementation is achieved in the gear shifting process of the motor and the engine, the requirement for gear shifting time is low, and gear shifting reliability is high.
本发明涉及一种多工作模式并联混合动力系统,所述电机变速模块的内部设置有第二离合装置(13),所述发动机变速模块的输出端与所述电机输入齿轮副的输出端之间设置有第三离合装置(14),通过所述第二离合装置(13)及第三离合装置(14)的通断切换实现该混合动力系统不同工作模式的切换;电机和发动机可以独立换挡,换挡过程中保持动力传输连续不中断;提高纯电驱动能力,增大起步扭矩;分别设置有发动机和电机独立驱动模式,在高速工况下,驱动效率更高;电机和发动机换挡过程中实现动力互补,对换挡时间要求低,换挡可靠性高。
