Power distribution fire fighting truck power system special for hybrid power airport

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; ...

AI Technical Summary

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
