The invention discloses a power split hybrid power speed change mechanism which comprises an engine crankshaft, a torsion damper is installed at one end of the engine crankshaft, one end of the torsion damper is in transmission connection with an input shaft, and a planetary power split structure is fixedly connected to the input shaft. Power input by an engine crankshaft is divided through a planetary power dividing structure, part of the power is independently generated, part of the power is used for driving a vehicle, one end of the planetary power dividing structure is connected with a gear ring output shaft, the gear ring output shaft is fixedly connected with a power output shaft, and the gear ring output shaft is fixedly connected with a speed reduction driving part. Oil can be saved in all working conditions and all regions; a gear shifting system is omitted, the structure is simple, and cost is low; the integration level is high, the efficiency of the whole hybrid power system is improved, meanwhile, the failure risk of the connecting structure is reduced, and the system reliability is high.

    本发明公开了一种功率分流混合动力变速机构,包括发动机曲轴,所述发动机曲轴一端安装有扭转减震器,所述扭转减振器一端与输入轴连接传动,所述输入轴上固定连接有行星功率分流结构,通过行星功率分流结构将发动机曲轴输入的动力分流,部分进行独立发电,部分进行驱动车辆,所述行星功率分流结构一端连接有齿圈输出轴,所述齿圈输出轴与动力输出轴固定连接,所述齿圈输出轴上固定连接有减速驱动部,其优点在于,可以全工况、全地域节油;无换挡系统,结构简单、成本低;集成度高,提升整个混合动力系统效率,同时减少连接结构失效风险,系统可靠度高。
