The invention discloses a dual-motor series-parallel connection commercial vehicle hybrid power system, which belongs to the technical field of commercial vehicle hybrid power systems, and comprises an engine, a first motor, a second motor, a main transmission shaft, an input shaft and a drive axle, the output end of the engine is connected with an input shaft through a clutch, and a gear shifting executing mechanism capable of being connected or disconnected with the main transmission shaft is connected to the input shaft. The first motor is in transmission connection with the main transmission shaft; the main transmission shaft is in transmission connection with the drive axle through the four-gear gearbox; the second motor is in transmission connection with the input shaft. An engine and a dual-motor power system are adopted, three modes including a pure electric mode (single-motor driving and dual-motor driving), a series hybrid mode and a parallel hybrid mode can be achieved, the overall structure is simple, the reliability is high, the failure rate is low, the transmission power is large, the transmission ratio range is wide, the endurance mileage is high, the universality is good, and the application range is wide. And the requirements of most application scenes of heavy commercial vehicles can be met.

    本发明公开一种双电机串并联商用车混合动力系统,属于商用车混合动力系统技术领域,包括发动机、第一电机、第二电机、主传动轴、输入轴和驱动桥;发动机输出端通过离合器与输入轴连接,输入轴上连接安装有能够与主传动轴连接或断开的换挡执行机构;第一电机与主传动轴传动连接;主传动轴通过四挡变速箱与驱动桥传动连接;第二电机与输入轴传动连接。采用发动机和双电机动力系统,可实现三种模式:纯电模式(单电机驱动和双电机驱动)、串联混动模式和并联混动模式,整体结构简单,可靠性高,故障率低,传动功率大、传动比范围广,具有较高的续航里程,且普适性好,能满足重型商用车多数应用场景的需求。
