Description
Technical field
The utility model relates to a kind of vehicle tyre and charges and discharge the gas parts, specifically, relates to a kind of module, charges and discharge gas control valve and venting control control valve, is not only applicable to military vehicle, also is applicable to civilian vehicle.
Background technique
Offroad vehicle 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 performance of passing through of automobile, thereby improve the mobility and the vital capacity of automobile greatly.
When the height of transporting cars is limited by bridge opening, culvert, mother aircraft door etc., in certain scope,, the automobile total height is suitably reduced, just can pass through smoothly if reduce tire pressure.
When automobile 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 air pressure; If can give the venting of automobile tire in the process of moving in real time, can avoid the generation of dangerous situation.
Military offroad vehicle 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 mobility, Security and the vital capacity of military supplies according to different condition of road surface.
At present, do not find cross-country vehicle tire central authorities charging and discharging valve assembly automatically in the prior art as yet.
Summary of the invention
The purpose of this utility model is to overcome the problem and shortage that prior art exists, and provides a kind of cross-country vehicle tire central authorities automatic charging and discharging valve assembly, makes vehicle in the process of travelling, and in real time tire is charged and discharged gas, pressure measurement and pressurize automatically.
The purpose of this utility model is achieved in that
By Fig. 1, Fig. 2, Fig. 3, Fig. 4 as can be known, the utility model is front-wheel to be installed charge and discharge gas control valve 2, venting control valve 3, source of the gas intake interface 4, trailing wheel and charge and discharge gas control valve 5, trailing wheel and charge and discharge gas interface 6, trailing wheel baroceptor 7, high-pressure limiting valve 8, low pressure pressure-limit valve 9, front-wheel baroceptor 11, front-wheel and charge and discharge gas interface 12 on module 1;
Described module 1 is a kind of rectangular sheet metal, is the platform of fixing above-mentioned parts, is processed with the first pipeline 1.1-the 7th pipeline 1.7 of communication means in it;
Front-wheel charges and discharge gas control valve 2, trailing wheel charges and discharge gas control valve 5 and is communicated with by first pipeline 1.1;
Front-wheel charges and discharge gas control valve 2, front-wheel baroceptor 11 and front-wheel and charges and discharge gas interface 13 by the 4th pipeline 1.4 and 1.2 connections of second pipeline;
Source of the gas intake interface 5 and high-pressure limiting valve 8 are communicated with by the 6th pipeline 1.6;
Trailing wheel charges and discharge gas control valve 5, trailing wheel baroceptor 7 and trailing wheel and charges and discharge gas interface 6 by the 7th pipeline 1.7 and 1.3 connections of the 3rd pipeline.
The utility model working principle:
Detection of the present utility model and control are to be finished automatically by special detection control system, and the utility model only provides a valve assembly, are matching used with special detection control system.
One, tyre inflation
1, front tyre inflation pressurized gas is entered by source of the gas intake interface 4, connects front-wheel and charges and discharge gas control valve 2, and gas is to front-wheel; Disconnect inflating when front-wheel charges and discharge gas control valve 2 and stop.
2, rear tyre inflation pressurized gas is entered by source of the gas intake interface 4, connects trailing wheel and charges and discharge gas control valve 5, and gas is to trailing wheel; Disconnect inflating when trailing wheel charges and discharge gas control valve 5 and stop.
3, the front and back wheel tire is inflated simultaneously: pressurized gas is entered by source of the gas intake interface 4, connects simultaneously that front-wheel charges and discharge gas control valve 2 and trailing wheel charges and discharge gas control valve 5, and gas is to front and rear wheel; Inflation stops when disconnecting control valve.
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 valve 3, and gas is through 9 venting of low pressure pressure-limit valve; Disconnecting exits when front-wheel charges and discharge gas control valve 2 and venting control valve 3 stops.

Three, automatic voltage measurement
By front and rear wheel baroceptor 11,7 air pressure is converted to electrical signal and shows current atmospheric pressure value, baroceptor is set high-voltage value and low voltage value, when tire pressure was higher or lower than range of set value, the forward and backward gas control valve 2,5 that charges and discharge was opened automatically; The air pressure show value is current front and rear wheel air pressure value.
Four, high voltage protective
When inner gas pressure surpassed the high pressure rating value, opened automatically by high-pressure limiting valve 8 in gas replenishment process for wheel tyre, prevents that the tire high pressure from blowing out or shorten normal working life of tire.
Five, low pressure pressure limiting
When reaching the minimum setting value of tire, low pressure pressure-limit valve 9 cuts out wheel tyre automatically in deflation course, keeps vehicle minimum tire pressure value when cross-country run.
The utlity model has following advantage and good effect:
Mainly be installed on the wheeled vehicle of some specific uses.In vehicle driving or in stopping, the driver in operator cabin 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 used the mobility and the vital capacity that can improve vehicle on wheel military vehicle.
At present external some country in addition central air-charging and air-discharging system as the modern sign of offroad vehicle, so this device extends to civilian cross-country, transport field.
