Parallel oil-electricity hybrid airport fire fighting truck chassis

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of fire protection, in particular to a chassis of a parallel oil-electric hybrid airport fire truck. Background technique [0002] The special chassis frame for airport fire trucks is used for airport fire rescue. At present, a typical chassis frame for airport fire trucks has one or two high-horsepower engines. If one engine is used, a power splitter needs to be installed. The engine can drive the vehicle and the engine at the same time. Fire water pump; with two engines, one of the engines can be used as both a vehicle drive and a fire truck pump. The engine is limited by its own output characteristics, and its starting acceleration performance is poor. For an engine drive solution, the supplier of key assembly resources is relatively single, and the cost remains high, which is not conducive to the development of the industry. Engine emissions affect the environment, and the exhaust gas generated by start...

The engine is limited by its own output characteristics, and the starting acceleration performance is poor

For an engine drive solution, the supplier of key assembly resources is relatively single, and the cost remains high, which is not conducive to the development of the industry. Engine emissions affect the environment, and the exhaust gas generated by starting in the parking garage needs to be specially treated. The vehicle needs to be driven to take power, and It is required that the vehicle can run at different speeds when the water pump is pumping water at full power. This power take-off method is difficult to realize, and it needs to rely on imported components
