The invention discloses a hybrid power system of a heavy truck. The hybrid power system comprises an engine; the torsional damper is connected with the output end of the engine; a special gearbox for hybrid power comprises a main box connected with a torsion damper and an auxiliary box connected with the main box. The driving motor set comprises an EM1 motor and an EM2 motor which are connected with the special hybrid gearbox; and the output device is connected with the special hybrid gearbox. According to the hybrid power system, the engine and the driving motor set are subjected to gear matching through the gear shifting executing mechanism A, the gear shifting executing mechanism B, the gear shifting executing mechanism C and the gear shifting executing mechanism D, a pure electric mode, a series hybrid mode, a parallel hybrid mode and a power split hybrid mode can be achieved, and oil consumption of the driving system is greatly reduced; and meanwhile, when each gear shifting actuator performs gear shifting, only one of the engine and the EM2 motor serving as main driving sources participates in the gear shifting process, and the other driving source can continuously drive the vehicle, so that gear shifting without power interruption is realized.
本发明公开了一种重卡载货车混合动力系统包括:发动机;扭转减震器,与所述发动机输出端连接;混动专用变速箱,包括与扭转减震器连接的主箱,以及与所述主箱连接的副箱;驱动电机组,包括与混动专用变速箱连接的EM1电机、EM2电机;输出装置,与混动专用变速箱连接。本发明提供了一款混合动力系统,发动机和驱动电机组通过换挡执行机构A、换挡执行机构B、换挡执行机构C、换挡执行机构D进行挡位匹配,可实现纯电模式、串联混动模式、并联混动模式、功率分流混动模式,大大降低驱动系统的油耗,同时在每个换挡执行器在进行换挡时,发动机和EM2电机做为主驱动源仅有一个参与换挡过程,另一个驱动源可以继续驱动车辆,实现无动力中断换挡。
