Problems solved by technology

[0003] 1. The existing technology is a conventional diesel power system, which is poor in energy saving and environmental protection, and the power is insufficient;
[0004] 2. The existing technology is a pure electric power system. The problem of battery energy density leads to a short mileage of the vehicle and a short continuous working time of the fire pump;
[0005] 3. In the prior art, airport fire trucks respond slowly to fires and have a small radiation range
However, the water pump of this patent takes power from the drive motor through the power take-off, so the power distribution is single, and the power can only be distributed to the water pump through the drive motor for fire protection, which is not adaptable enough to meet the needs of use, so this problem is solved it becomes very necessary

Embodiment 1

[0032] like figure 1 As shown, this embodiment provides a power distribution hybrid power airport dedicated fire truck power system, including a drive motor, a motor / generator, a diesel engine, an EMT gearbox, a hybrid gearbox, a dedicated power transmission box, and a first steering Drive axle, second drive axle, third drive axle, energy storage system, bodywork pump, emergency steering pump; energy storage system includes high rate battery and BMS system. The chassis drive form of the system is 6*6, with three drive axles.

[0033] The power output EMT gearbox of the driving motor is connected to the input terminal 1 of the special power transmission box through the transmission shaft, and the power of the diesel engine, electric motor / generator, and hybrid transmission is connected to the input terminal 2 of the special power transmission box through the transmission shaft. The special power transmission box couples the two-way power and then outputs it to the bodywork pum...

Embodiment 2

[0036] like figure 2 As shown, this embodiment provides a pure electric drive working condition: under this working condition, the motor / generator is an electric motor, the energy storage system provides energy for the driving motor and the electric motor, and the output power of the driving motor is transferred to the power through the EMT gearbox and transmission shaft. It is transmitted to the input end 1 of the special power transmission box, and the output power of the motor is transmitted to the input end 2 of the special power transmission box through the hybrid gearbox and transmission shaft. The power is transmitted to the emergency steering pump, the first steering drive axle, and the second drive axle respectively through the transmission shaft, and the power is transmitted from the second drive axle to the third drive axle to provide power for the chassis. At this time, the diesel engine is in a stop state and does not participate in Chassis power drive, driven pu...

Embodiment 3

[0038] like image 3 As shown, this embodiment provides a hybrid driving condition: under this condition, the motor / generator is an electric motor, the energy storage system provides energy for the driving motor and the electric motor, and the output power of the driving motor is transmitted to the Input terminal 1 of the dedicated power transmission box, the power of the diesel engine and the motor / generator is coupled through the hybrid gearbox, and after coupling, it is transmitted to the input terminal 2 of the dedicated power transmission box through the transmission shaft. At this time, the input terminal 1 of the dedicated power transmission box , the power input special power transmission box of the input terminal 2 is coupled, and the coupled power is transmitted to the emergency steering pump, the first steering drive axle, and the second drive axle respectively through the transmission shaft, and the second drive axle transmits power to the third drive axle , so as ...

Abstract

The invention aims at providing a power distribution fire fighting truck power system special for a hybrid power airport. The power distribution fire fighting truck power system comprises a driving motor, a motor / generator and a diesel engine. The driving motor outputs power to an EMT gearbox and is connected with the first input end of a special power transmission box through a transmission shaft. The driving motor is connected with an energy storage system; the diesel engine and the motor / generator are jointly connected with the hybrid gearbox, and power of the hybrid gearbox is connected to the second input end of the special power transmission box through the transmission shaft. The motor / generator is connected with the energy storage system; and the power transmission box outputs power to a loading pump and an emergency steering pump through the transmission shaft. Power of the driving motor, the diesel engine and the motor / generator is coupled through the special power transmission box and then transmitted to a drive axle for driving, and transmitted to the loading pump for fire fighting.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a power distribution hybrid power airport special fire truck power system. Background technique [0002] When a fire accident occurs at the airport, it is urgent to carry out fire fighting at the accident site. The power system of the airport fire truck currently used is a diesel engine; its response time to the fire is relatively slow; the center of gravity of the vehicle is relatively high, which is easy to cause rollover; power Performance and acceleration are limited. Defects and deficiencies of the prior art: [0003] 1. The existing technology is a conventional diesel power system, which is poor in energy saving and environmental protection, and the power is insufficient; [0004] 2. The existing technology is a pure electric power system. The problem of battery energy density leads to a short mileage of the vehicle and a short continuous working time of the fire pump; ...
