Cross-country vehicle tire central authorities air inflation discharging control device
Technical field
The present invention relates to a kind of vehicle tyre and charge and discharge the gas parts, specifically, relate to the central air inflation discharging control device of a kind of cross-country vehicle tire, be not only applicable to military-designed vehicle, also be applicable to civil car.
Background technology
Cross country car usually need in sand ground, ice-snow field, hasty expedient road, farmland or muddy ground is up be sailed.At this moment, if when automobile travels with normal tire pressure, just might take place to fall into car or skid.If the reduction tire pressure increases tractive force, can improve the through performance of automobile, thereby improve the manoevreability and the viability of automobile greatly.
When the height of transporting cars is limited by bridge opening, culvert, mother aircraft door etc.,,, passes through smoothly the automobile bottom-to-top-height just suitably being reduced if in certain scope, reduce tire pressure.
When motor tire is punctured with quilt that attack is worn,, can make automobile leave the danger zone as early as possible or arrive the destination if can give in the process of moving automobile tyre inflation in real time.
When the higher and automobile long-distance of road environment temperature travels continuously,, may cause tyre break because the tire heating raises the tire internal gas pressure; If can give the venting of motor tire in the process of moving in real time, can avoid the generation of dangerous situation.
Military cross country car is when transporting weaponry, vehicular weapons system, traffic guidance system and the battlefield wounded, slow down impact and vibration if can adjust tire pressure in real time, can strengthen manoevreability, safety and the viability of military supplies according to different condition of road surfaces.
At present, do not find cross-country vehicle tire central authorities air inflation discharging control device in the prior art as yet.
Summary of the invention
The objective of the invention is to overcome the problem and shortage that prior art exists, provide a kind of cross-country vehicle tire central air inflation discharging control device.
The object of the present invention is achieved like this:
By Fig. 1, Fig. 2, Fig. 3, Fig. 4 as can be known, the present invention is that module 1 is provided with front-wheel and charges and discharge gas control valve 2, venting control cock 3, source of the gas control cock 4, source of the gas intake interface 5, trailing wheel and charge and discharge gas control valve 6, trailing wheel and charge and discharge gas interface 8, high-pressure limiting valve 9, air-pressure gauge interface 10, low pressure limiting valve 11, front-wheel and charge and discharge gas interface 13;
Described module 1 is a kind of rectangular metal sheet, is the platform of fixing above-mentioned parts, is processed with the first pipeline 1.1-the 7th pipeline 1.7 of communication means on it;
Front-wheel charges and discharge gas control valve 2, trailing wheel charges and discharge gas control valve 6 and is communicated with by first pipeline 1.1;

Venting control cock 3 and low pressure limiting valve 11 are communicated with by the 5th pipeline 1.5;
Source of the gas intake interface 5, source of the gas control cock 4, high-pressure limiting valve 9, air-pressure gauge interface 10 are communicated with by the 8th pipeline 1.8 and the 6th pipeline 1.6;
Trailing wheel charges and discharge gas control valve 6 and trailing wheel charges and discharge gas interface 8 by the 7th pipeline 1.7 and 1.3 connections of the 3rd pipeline;
Power interface assembly 7 charges and discharge gas control valve 2, venting control cock 3, source of the gas control cock 4, trailing wheel with front-wheel respectively and charges and discharge gas control valve 6 and be electrically connected.
Principle of work of the present invention:
Before the work of the present invention, front-wheel charges and discharge gas interface 13 and front tyre is communicated with, and trailing wheel charges and discharge gas interface 8 and rear tyre is communicated with, and source of the gas intake interface 5 and source of the gas are communicated with, and air-pressure gauge interface 10 and air-pressure gauge are communicated with.
One, inflation of tire
1, front tyre inflation is connected source of the gas control cock 4 and front-wheel charges and discharge gas control valve 3 simultaneously, and the gas of source of the gas charges and discharge gas interface 13 to front tyre through front-wheel.
2, rear tyre inflation is connected source of the gas control cock 4 and trailing wheel charges and discharge gas control valve 6 simultaneously, and the gas of source of the gas charges and discharge gas interface 8 to rear tyre through trailing wheel.
3, forward and backward tire is inflated simultaneously and is connected source of the gas control cock 4 simultaneously, front-wheel charges and discharge gas control valve 3 and trailing wheel charges and discharge gas control valve 6, and the gas of source of the gas is respectively to front tyre and rear tyre.
Two, bleed a tire
1, the front tyre venting is connected front-wheel simultaneously and is charged and discharged gas control valve 2 and venting control cock 3, and the gas of front tyre is through 11 venting of low pressure limiting valve.
2, the rear tyre venting is connected trailing wheel simultaneously and is charged and discharged gas control valve 6 and venting control cock 3, and the gas of rear tyre is through 11 venting of low pressure limiting valve.
3, forward and backward tire is exitted simultaneously and is connected front-wheel simultaneously and charge and discharge gas control valve 2, trailing wheel and charge and discharge gas control valve 6 and venting control cock 3, and the gas of front tyre and rear tyre is through 11 venting of low pressure limiting valve.
Three, front and rear wheel barometric surveying
Connect front-wheel and charge and discharge gas control valve 2, the air-pressure gauge displayed value is the atmospheric pressure value of current front-wheel.In like manner, connect trailing wheel and charge and discharge gas control valve 6, the air-pressure gauge displayed value is the atmospheric pressure value when front and back wheel.
Four, high voltage protective
When inner gas pressure surpassed the high pressure rated value, high-pressure limiting valve 9 self-openings prevented that the tire high pressure from blowing out or shorten normal service life of tire to wheel in gas replenishment process.
Five, low pressure pressure limiting
When reaching the minimum setting value of tire, low pressure limiting valve 11 SELF CL keep vehicle minimum tire pressure value when land locomotion to wheel in deflation course.
The present invention has the following advantages and good effect:
Mainly be installed on the wheeled car of some special purposes.In vehicle ' or in stopping, chaufeur in operator's compartment by simple operations just can inflate automatically vehicle tyre, venting or pressure measurement, with the adjusting of realization to tire pressure, thereby raising tire or vehicle are by the ability of complex road surfaces such as desert, mire or ice and snow.
This device is applied in the manoevreability and the viability that can improve vehicle on the wheel military vehicle.
This device is also extended to civilian cross-country, transport field.
