Embodiment 1

[0072] Such as figure 1 As shown, a pure electric airport-specific fire engine power system includes a driving motor 15, a power transfer case 17, a power take-off 18, and a second steering drive axle 22;

[0073] The driving motor 15 is connected to the power transfer case 17 through a transmission shaft;

[0074] The power transfer case 17 is connected to the second steering drive axle 22 through a transmission shaft;

[0075] The power transfer case 17 transmits power to the bodywork equipment through the power take-off 18.

[0076] The working process and principle of Embodiment 1 of the present invention:

[0077] 1. According to whether power take-offs are used for the bodywork, there are three working methods:

[0078] (1) When driving without taking power, the driving motor 15 transmits the power to the second steering drive axle 22 through the power transfer case 17, so as to realize the demand for driving without taking power;

[0079] (2) Driving power take-off conditions, the ...

Abstract

The invention discloses a special pure electric airport fire-fighting truck power system, and relates to the technical field of vehicles. The special pure electric airport fire-fighting truck power system includes a driving motor, a power transfer case, a force taking device and a steering driving axle. Compared with a conventional diesel power system, the special pure electric airport fire-fighting truck power system is high in power performance, energy saving, environment-friendly, high in power and smooth in driving, and is not prone to rollover when the speed is too high; and the responsespeed of a chassis and upper parts is fast, and the demand and use conditions of the upper part force taking are fully considered, one or more force taking devices are adopted, one part of power of the driving motor is distributed to the upper parts, such as a fire-fighting pump and other equipments. According to the special pure electric airport fire-fighting truck power system, full driving of the truck can be realized.

Description

Technical field [0001] The invention relates to the technical field of vehicles, in particular to a power system and a vehicle for a pure electric airport special fire truck. Background technique [0002] When a fire accident occurs at an airport, it is urgent to extinguish the fire at the scene of the accident. The current airport fire trucks are powered by diesel engines; their response time to the fire is relatively slow; the vehicle is prone to rollover; the power performance and acceleration performance are limited. [0003] The defects and shortcomings of the existing technology mainly include the following aspects: [0004] (1) The existing technology is a conventional diesel power system, which is poor in energy saving and environmental protection and has insufficient power; [0005] (2) When the speed is too fast, it is easy to roll over; [0006] (3) The response speed of bodywork and chassis to fire is slow. Summary of the invention [0007] In view of the above technical pr...
