The invention relates to the field of hybrid power vehicles, in particular to a hybrid power system and a commercial vehicle. The hybrid power system comprises an engine, a first clutch, a driving motor and a transmission which are sequentially connected, output shafts of the engine, the first clutch, the driving motor and the transmission are coaxial or parallel, the transmission is a single-planet-row transmission, and a planet row of the single-planet-row transmission is provided with a corresponding gear shifting mechanism. The transmission of the hybrid power system is set to be the single-planet-row transmission, the corresponding gear shifting mechanism is arranged for the transmission, the longitudinal length of the hybrid power system can be shortened on the premise that the gear shifting function of the transmission is kept, and therefore a platform product is formed; installation requirements of most occasions can be met directly or through fine adjustment, and therefore the problems that an existing hybrid power system is poor in universality due to the fact that the longitudinal length is long and cost is high due to the fact that a commercial vehicle needs to develop a special power system are solved.
本发明涉及混合动力车辆领域,特别是涉及到了一种混合动力系统及商用车。混合动力系统包括依次连接的发动机、第一离合器、驱动电机和变速器,发动机、第一离合器、驱动电机和变速器的输出轴同轴或者平行,变速器为单行星排变速器,单行星排变速器的行星排配置有对应的换档机构。本发明通过将混合动力系统的变速器设为单行星排变速器,并且为其配置了对应的换档机构,可在保持变速器换档功能的前提下,整体缩短混合动力系统的纵向长度,从而形成平台化产品,能够直接或者通过微调满足大多数场合的安装需求,进而决现有混合动力系统由于纵向长度长而导致的通用性差的问题以及商用车需开发专用的动力系统而导致的成本高的问题。
