Description
Technical field
The present invention relates to a kind of vehicle tyre and charge and discharge the gas parts, specifically, relate to a kind of module, charge and discharge gas control valve and venting control cock, 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., in certain scope,, the automobile bottom-to-top-height is suitably reduced, just can pass through smoothly if 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 automatically 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 authorities automatic air inflation discharging control device, make vehicle in the process of travelling, in real time tire is charged and discharged gas, pressure measurement and pressurize automatically.
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 equipped with front-wheel to charge and discharge gas control valve 2, venting control cock 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 limiting 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 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 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.
Principle of work of the present invention:
Detection of the present invention and control are to be finished automatically by special detection control system, and the present invention only provides a valve assembly, are matching used with special detection control system.
One, inflation of tire
1, front tyre inflation pressure 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 pressure 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: pressure 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 cock.
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 gas is through 9 venting of low pressure limiting valve; Disconnecting exits when front-wheel charges and discharge gas control valve 2 and venting control cock 3 stops.
2, the rear tyre venting is connected trailing wheel simultaneously and is charged and discharged gas control valve 5 and venting control cock 3, and gas is through 9 venting of low pressure limiting valve; Disconnecting exits when trailing wheel charges and discharge gas control valve 5 and venting control cock 3 stops.
3, the front and back wheel tire is exitted simultaneously and is connected front and rear wheel simultaneously and charge and discharge gas control valve 2,5 and venting control cock 3, and gas is through low pressure limiting valve 9 venting; Disconnecting exits when front and rear wheel charges and discharge gas control valve 2,5 and venting control cock 3 stops.
Three, automatic voltage measurement
By front and rear wheel baroceptor 11,7 air pressure is converted to electric signal and shows current atmospheric pressure value, baroceptor is set high-voltage value and low voltage value, when tire pressure is higher or lower than range of set value, forward and backward gas control valve 2,5 self-openings that charge and discharge; The air pressure displayed value is current front and rear wheel air pressure value.
Four, high voltage protective
When inner gas pressure surpassed the high pressure rated value, high-pressure limiting valve 8 self-openings prevented that the tire high pressure from blowing out or shorten normal service life of tire to wheel tyre in gas replenishment process.
Five, low pressure pressure limiting
When reaching the minimum setting value of tire, low pressure limiting valve 9 SELF CL keep vehicle minimum tire pressure value when land locomotion to wheel tyre 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 used the manoevreability and the viability 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 cross country car, so this device extends to civilian cross-country, transport field.
