The invention relates to the technical field of hybrid power gearboxes, in particular to a multi-mode hybrid power gearbox which comprises three power sources including an engine with a shock absorber, a generator and a driving motor, an electric control system for controlling the three power sources and the gearbox to work, and a gear transmission system connected with the three power sources and transmitting power of the three power sources. The gear transmission system is characterized in that by controlling opening and closing of a hydraulic control wet clutch in the gear transmission system and changing the position of a hydraulic control gear shifting synchronizer, engine power transmission path conversion and driving gear switching are achieved. According to the hybrid power gearbox, the number of gears, clutches and synchronizers is increased or decreased, so that sharing of most parts under the same design platform is achieved, and hybrid power gearbox products with three different functions of range extending, engine single-gear driving and engine two-gear driving can be produced on the same line.
本发明涉及混合动力变速箱技术领域,具体为一种多模式混合动力变速箱,包括:包括带减震器的发动机、发电机、驱动电机三个动力源,控制三动力源及变速箱工作的电控系统,以及连接三动力源并将其动力进行传递的齿轮传动系统,其特征在于通过对齿轮传动系统中液控湿式离合器的开闭控制和液控换档同步器位置变化,实现发动机动力传递路径的变换和驱动档位的切换。本发明通过齿轮、离合器、同步器的增减实现同一个设计平台下大部分零件共用,可以共线生产增程、发动机单档驱动、发动机两档驱动三款不同功能的混合动力变速箱产品。
