The invention belongs to the technical field of power transmission, and particularly relates to an automobile multi-mode multi-gear single-planet-row hybrid power transmission system which comprises an engine, a synchronizer, a one-way clutch, a first motor, a planet row assembly, an intermediate shaft gear, a speed reduction fixed shaft gear, a second motor and a speed reduction differential system. Three-gear pure electric driving (two-motor independent driving and double-motor driving) is achieved through a one-way clutch. In addition, two clutches are replaced by one synchronizer, an executing mechanism is simplified, the diversity of working modes is increased, an engine direct drive or parallel (single-motor and double-motor) hybrid power mode can be achieved on the basis of a traditional split-flow EVT configuration working mode, the working efficiency and redundancy reliability of the whole vehicle are improved, and the service life of the whole vehicle is prolonged. And the economical efficiency and the dynamic property of the hybrid electric vehicle are improved.
本发明属于动力传动技术领域,具体涉及汽车多模式多档位单行星排混合动力传动系统,包括发动机、同步器、单向离合器、第一电机、行星排组件、中间轴齿轮、减速定轴齿轮、第二电机和减速差速系统。通过单向离合器实现三档纯电动驱动(两电机单独驱动、双电机驱动)。此外通过一个同步器替代两个离合器,简化了执行机构,增加了工作模式的多样性,在传统分流EVT构型工作模式基础上,可以实现发动机直驱或并联(单电机、双电机)混合动力模式,提高了整车工作效率与冗余可靠性,改善了混合动力汽车的经济性及动力性。
