Abstract
A centralized inflating-deflating controller for the tyres of cross-country car features that the inflating-deflating control valves and interfaces for front and back tyres, deflating control valve, air source control valve and inlet interface, high and low pressure limiting valves and pressure meter interface are installed on a module.
Description
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;
