The invention relates to the technical field of fire fighting, in particular to a parallel oil-electricity hybrid airport fire fighting truck chassis which comprises a chassis frame wheel frame and awater pump; the fire fighting truck chassis further comprises an engine, a driving motor, a power coupling box, an electric generator in transmission fit with the engine and a power battery; the output end of the engine is in transmission connection with a speed changing box, the output end of the speed changing box is in transmission connection with a first transmission shaft, the output end of the driving motor is in transmission connection with a second transmission shaft, the first transmission shaft and the second transmission shaft are both in transmission connection with the power coupling box, and the output end of the power coupling box is in transmission connection with a third transmission shaft; and the other end of the third transmission shaft is in transmission connection with a full-drive transfer case, and the electric generator and the driving motor are both electrically connected with the power battery. According to the parallel oil-electricity hybrid airport fire fighting truck chassis, the engine and the driving motor are connected in parallel for hybrid driving, so that the problem that the starting acceleration performance of the engine is poor is solved, theacceleration performance is improved, and the emission is reduced.
