The invention relates to the technical field of engine chassis, in particular to a serial hybrid drive chassis special for an airport fire fighting truck. The chassis comprises an engine, a generator,a chassis transmission system and a plurality of drive motors, wherein the generator is also electrically connected with a power battery, the chassis transmission system comprises a chassis frame which is of a rectangular structure and a plurality of drive axles, and a water pump motor is further arranged on the chassis frame. According to the chassis, the engine and the drive motors are connected in series for hybrid drive, the front and rear dual-drive motors are adopted for drive, and the problem of poor starting acceleration performance of the engine is solved; the engine does not participate in direct drive and converts energy into electric energy to participate in drive of the truck, the started engine can output power and torque in a fuel economy area, the fuel economy of the wholetruck is improve, and the emission is reduced; and when the truck leaves a garage, the truck-mounted power battery supplies power to the drive motors, the engine is temporarily not started, and the problem of waste gas emission in the garage is solved.

    本发明涉及发动机底盘技术领域,具体是一种串联混动机场消防车专用底盘,所述底盘包括有发动机、发电机、底盘传动系统和若干个驱动电机,所述发电机还电性连接有动力电池,所述底盘传动系统包括有矩形结构的底盘架和若干个驱动桥,所述底盘架上还设置有水泵电机,本发明采用发动机和驱动电机串联混合驱动,采用前后双驱动电机驱动,解决了发动机启动加速性能较差的问题,发动机不参与直接驱动,通过转化为电能参与车辆的驱动,启动后的发动机可在燃油经济性区输出功率和扭矩,提高了整车燃油经济性,降低了排放,在车辆出车库时,车载动力电池给驱动电机供电,发动机暂不启动,解决了车库废气排放的问题。
