The invention discloses a power transmission system of a hybrid power forklift and a control method thereof. The power transmission system comprises an engine assembly, a transmission system, a walking system, an operation system, a whole vehicle controller and a control system. The engine assembly comprises a fuel engine assembly, an ISG motor assembly and a storage battery assembly, the ISG motor assembly drives the fuel engine assembly to be started, and meanwhile the traveling system and the operation system are driven through the transmission system. The fuel engine assembly drives the ISG motor assembly to generate power and charge the storage battery assembly; the control system controls the clutches and the brakes through the vehicle control unit to achieve switching of the controlmodes. The fuel oil engine has the beneficial effects that the fuel oil engine can work in a high-efficiency area, the ISG motor assembly assists the fuel oil engine in working under severe working conditions, so that emission and oil consumption of the fuel oil engine are controlled, and the ISG motor assembly serves as a generator to charge the storage battery assembly when the fuel oil enginehas surplus power.

    本发明公开了一种混合动力叉车的动力传动系统及其控制方法,包括发动机总成、传动系统、行走系统、作业系统、整车控制器和操控系统;所述发动机总成包括燃油发动机总成、ISG电机总成和蓄电池总成,所述ISG电机总成驱动燃油发动机总成启动,同时通过传动系统分别驱动行走系统和作业系统;所述燃油发动机总成驱动ISG电机总成发电并且给蓄电池总成充电;所述操控系统通过整车控制器控制各离合器和制动器实现各控制模式的切换。有益效果:本发明能够使燃油发动机处于高效率区工作,ISG电机总成在恶劣工况下辅助燃油发动机工作,从而控制燃油发动机的排放和油耗,ISG电机总成在燃油发动机富余功率时,充当发电机给蓄电池总成充电。
