The invention relates to an infinitely variable speed dual-motor multi-mode hybrid power system, which belongs to the technical field of hybrid electric vehicles and comprises a variable speed transmission structure, the variable speed transmission structure comprises a transmission, a through hole in the axial direction is formed in an input shaft of the transmission, and a transmission shaft is rotatably connected in the through hole; the transmission shaft is selectively in transmission connection or disconnection with the engine and the first motor; the first clutch actuator is used for combining or disconnecting the transmission shaft and the input shaft of the transmission; and the input end of the final power output mechanism is in transmission connection with the output end of the transmission. When the engine is started, the engine can be disconnected from the transmission shaft, complete decoupling of the engine in the starting process is achieved, and starting torque redundancy is high; the transmission shaft and the transmission input shaft are disconnected through the first clutch actuator, the engine directly drives the first motor to generate electricity through the transmission shaft, and the energy conversion and utilization rate is high; meanwhile, the transmission shaft is located in the through hole of the transmission input shaft, and the arrangement space is higher in redundancy compared with a traditional fuel engine.

    本申请涉及一种无极变速双电机多模混动系统,属于混合动力汽车技术领域,包括变速传动结构,变速传动结构包括变速器,变速器的输入轴内设置有沿轴向方向的通孔,通孔的内部转动连接有传动轴,传动轴选择性地与发动机、第一电机传动连接或断开连接;第一离合执行器,以使传动轴和变速器的输入轴结合或断开;最终动力输出机构,其输入端与变速器的输出端传动连接。在发动机启动时能与传动轴断开,实现启动过程发动机完全解耦,启动扭矩冗余度高;通过第一离合执行器使传动轴和变速器输入轴断开,发动机直接通过传动轴带动第一电机进行发电,能量转换和利用率高;同时传动轴位于变速器输入轴的通孔内,布置空间较传统燃油机布置冗余度较高。
