Abstract
The utility model provides a wheelside valve which can be applied to the inflation-deflation system in the center of off-road car tyre, comprising a base which is provided with an air inlet, an air outlet, and a valve body which is connected with the base. The air inlet and the air outlet are respectively communicated with the lower part of the chamber of the valve through the airway. The inner part of the chamber of the valve is provided with a wire ring, a fixed gag bit, a moving gag bit and a reset spring connected between the fixed gag bit and the moving gag bit. The lower end of the moving gag bit is in contact with the lower part of the chamber to separate the air inlet and the air outlet. A further improvement is made to provide a gas valve which is communicated with the air outlet through the airway on the base. The utility model is provided with the air inlet to connect the tyre when in operation, the fixed gag bit magnetizes the moving gag bit. The air inlet and the air outlet are then communicated to fulfill the inflation or deflation of the tyre. When the wire ring is de-electrified, the inflation or the deflation is stopped. When the tyre central deflation system is not used, the tyre inflation or deflation can be realized through the air valve and the use of the car will no be affected.
Description
Technical field
The utility model relates to the wheel limit valve in the Center Tyre Inflation that cross country car uses.
Background technology
The Center Tyre Inflation of existing cross country car, a holonomic system of forming by compressed air gas source, control gas circuit, rotary seal air chamber, wheel limit valve and corresponding pipeline, be used to regulate the air pressure of tire, to satisfy the different needs of different road surfaces, can greatly improve the crossing ability of wheeled car on soft and muddy road surface to vehicle tyre air pressure.Can be applied in easily on wheeled armored vehicle and corresponding military cross country car or the civil transport vehicle, improve vehicle in the desert, the ability of walking of ice and snow road, swampy terrain, shorten time of run, improve operating efficiency, saving fuel, the equipment and the period of service of prolongation vehicle.
Wheel limit valve is installed on the wheel rim, and the existing limit valve of taking turns when regulating vehicle tyre air pressure, needs shut-down operation for manually, can not satisfy the different needs of different road surfaces to vehicle tyre air pressure.
In order to realize not shut-down operation, design new Center Tyre Inflation, by the holonomic system that compressed air gas source, control circuit and control gas circuit, rotary seal air chamber, wheel limit valve and corresponding pipeline are formed, be used to regulate and monitor the air pressure of tire, realize not being open to traffic operation.
Summary of the invention
Need shut-down operation at existing wheel limit valve, can not satisfy the defective of different road surfaces, the utility model proposes and realize the not supporting automobile-used limit valve of taking turns of Center Tyre Inflation of shut-down operation the different needs of vehicle tyre air pressure.
For this reason, the technical solution of the utility model is: the automobile-used limit valve of taking turns, comprise base, and base is provided with admission port, air extractor duct, it is characterized in that: also have a valve body to be connected with base, admission port, air extractor duct are communicated with the chamber bottom of valve body by air flue respectively; Be furnished with coil, static gag bit, moving armature in the chamber of valve body, be provided with retracing spring between static gag bit and moving armature, the moving armature lower end contacts with the chamber bottom of valve body, cuts off admission port and air extractor duct.
To further improvement in the technical proposal, be on base, to be provided with valve to be communicated with air extractor duct by air flue.
Beneficial effect: use the utility model, air extractor duct is connected with tire, in the time of need carrying out inflation of tire or venting, driving in-house operation, coil electricity, overcome the resistance of retracing spring, static gag bit adhesive moving armature, admission port, air extractor duct are communicated with, gas enters tire through admission port, air extractor duct, finishes inflation of tire or venting; Coil blackout, inflation or venting stop.
Under the state that does not use Center Tyre Inflation, can put on the air or exit to tire by valve, do not influence the use of car load.
This utility model essence is an electromagnetic valve, can realize not shut-down operation, to satisfy the different needs of different road surfaces to vehicle tyre air pressure.
Description of drawings
Fig. 1 is a structure cutaway view of the present utility model.
Fig. 2 is the left view of utility model shown in Figure 1.
The specific embodiment
Further describe the utility model in conjunction with Fig. 1,2.The automobile-used limit valve of taking turns, on base 6, be provided with admission port 8, air extractor duct 7, admission port 8 and air extractor duct 7 coaxial settings, valve body 9 and base 6 are by being threaded, seal ring 5 guarantees the sealing of the chamber of valve body 9 in the junction, and admission port 8, air extractor duct 7 are communicated with the chamber bottom of valve body 9 by air flue respectively; Be furnished with coil 1, static gag bit 2, moving armature 3 in the chamber of valve body 9, be provided with retracing spring 4 between static gag bit 2 and moving armature 3, moving armature 3 lower ends contact with the chamber bottom of valve body 9, cut off admission port 8 and air extractor duct 7.Being provided with valve 11 on base 6 is communicated with air extractor duct 7 by air flue.
The purpose of valve 11 is set, and is under the state that does not use Center Tyre Inflation, puts on the air or exits to tire by valve 11, makes automobile-used more perfect functions of taking turns the limit valve.The automobile-used limit valve of taking turns that valve is not set can satisfy use.
As shown in Figure 1, in moving armature 3, be provided with air flue 10, the air flue 10 normal container cavities that are communicated with air extractor duct 7, retracing spring 4.Guarantee coil 1 must not the electricity situation under, in the container cavity of the retracing spring 4 of moving armature 3 upper ends gaseous tension is arranged all the time, in conjunction with the dynamics of retracing spring 4, guarantee that further moving armature 3 reliably contacts with the chamber bottom of valve body 9, improve the reliability that cuts off admission port 8 and air extractor duct 7.
Claims (3)
1, the automobile-used limit valve of taking turns comprises base, and base is provided with admission port, air extractor duct, it is characterized in that: also have a valve body to be connected with base, admission port, air extractor duct are communicated with the chamber bottom of valve body by air flue respectively; Be furnished with coil, static gag bit, moving armature in the chamber of valve body, be provided with retracing spring between static gag bit and moving armature, the moving armature lower end contacts with the chamber bottom of valve body, cuts off admission port and air extractor duct.
