Abstract
The invention discloses an automobile tyre valve and relates to a valve for inflating and deflating the vehicle, in particular to an automobile tyre valve of central inflation/deflation system of off-road vehicle tyre. The invention comprises an I-shaped obturating ring (1), a valve body (2), an O-shaped obturating ring (3), an elastic inner clip (4), a spring (5), a valve cover (6), a dust cap (7), a nut (8), a valve core (9), a membrane disk (10) and a membrane (11). The invention has a simple structure, low manufacturing cost and good pressure-keeping effect to the air pressure of the tyre, can ensure the rotary sealing air chamber has no air pressure when the vehicle drives to decrease the abrasion of the obturating ring, simplifies the structure of the central inflation/deflation system and decreases the hardware configuration of the vehicle.
Description
Technical field
The present invention relates to a kind of automobile tire charging and discharging valve, relate in particular to a kind of automobile tyre valve of cross-country vehicle tire central air-charging and air-discharging system.
Background technique
Think that abroad automobile tyre valve is the parts of most critical in the Center Tyre Inflation.The improvement of external Center Tyre Inflation structure is nearly all relevant with the variation of automobile tyre valve with development.The structure of automobile tyre valve, function and characteristics are not only determining the structure of the maneuver control device of system, are determining the sealing requirements of rotary seal air chamber and influence ring wear speed, are also determining to charge and discharge the speed of gas speed; Affect the reliability of system's tire pressurize and the convenience of operation in addition.
The automobile tyre valve of most of central air-charging and air-discharging systems of Russia, the current equipment of the U.S. is the form that adopts blocking-valve, and reality only is a hand switch that is contained in tyre beads, opening and closing after it must stop.If close-lock valve when travelling then can't detection wheel air pressure and regulating wheel air pressure; If the palpus using system must stop and open locking valve, under urgent or dangerous situation, all is disadvantageous.If open blocking-valve when travelling, the rotary seal air chamber of tire will be filled with pressed gas, has quickened the wearing and tearing of rotating seal ring.Because tyre cavity is communicated with the rotary seal air chamber, the tire pressurize is too big to the dependence of rotating seal ring sealability, and the pressurize of tire has just become problem.If system pipeline gas leakage or fracture, blocking-valve do not keep the tire pressure function automatically, tire pressure will descend thereupon.
At present, French Lapie's nail (unit of length) company has developed Lapie's nail (unit of length) automobile tyre valve, U.S. Eaton has developed the Eton automobile tyre valve.The relation of Lapie's nail (unit of length) automobile tyre valve and rotary seal air chamber is unidirectional input, when pressure measurement, promptly the pressurized gas that come by air chamber enter automobile tyre valve, but when the automobile tyre valve internal air pressure is higher than the pressure of rotary seal air chamber, air-flow can not be through the automobile tyre valve reverse flow to the rotary seal air chamber, single tire pressure measurement mode can only be adopted when therefore this automobile tyre valve is used for central air-charging and air-discharging system, single bridge pressure measurement can not be used for.Wish simplified structure, the manufacturer that reduces cost or user for some, the system that requires single bridge or many bridges tire to control together can't adopt this automobile tyre valve.The structural principle of Lapie's nail (unit of length) automobile tyre valve does not provide the basis to simplified system, and another problem of Lapie's nail (unit of length) automobile tyre valve is that the measured value and the actual value of tire pressure exists than large deviation.The Eton automobile tyre valve has overcome two problems of Lapie's nail (unit of length) automobile tyre valve.But negative pressure (vacuum) control is adopted in the venting work of Eton automobile tyre valve.To this requirement, some automobile can be used original vacuum generating device, otherwise should dispose separately.The Eton automobile tyre valve also requires the rotary seal air chamber should have the two way sealed function, for the vehicle that adopts the planet gear type wheel reductor, this two way sealed Capability Requirement should be stricter, in case seal badly, gear oil in the retarder can be owing to the air chamber negative pressure flows in sealed air chamber, automobile tyre valve and the tire.
Summary of the invention
Purpose of the present invention just is to overcome the above-mentioned shortcoming and defect that prior art exists, and a kind of automobile tyre valve of cross-country vehicle tire central air-charging and air-discharging system is provided.
The object of the present invention is achieved like this:
Develop a kind of air chamber of Rational structure, realize pressurize, guarantee in the vehicle driving process inflation, venting, pressure measurement and pressurize tire to tire pressure.
As Fig. 1, automobile tyre valve comprises card 4, spring 5, valve gap 6, dust cap 7, nut 8, spool 9, diaphragm dish 10 and diaphragm 11 in worker's shape seal ring 1, valve body 2, O-ring seals 3, the elasticity.
Working principle of the present invention is:
The present invention only provides a valve assembly, is matching used with special detection control system.
When not having air-flow when A mouth a enters valve body 2, the compressive force of spring 5 is pressed in spool 9 on the air-flow path of valve body 2, and A mouth a and B mouth b turn-off, and then automobile tyre valve C is in off working state; When air-flow when A mouth a enters valve body 2, air-flow overcomes the compressive force of spring 5, and spool 9 is upwards pushed away the air-flow path of valve body 2, A mouth a is communicated with B mouth b, then automobile tyre valve C is in running order.
The present invention has following advantage and good effect:
1, valve body structure is simple, low cost of manufacture;
2, effective to the pressurize of tire pressure;
The rotary seal air chamber does not have air pressure when 3, guaranteeing vehicle driving, thereby reduces the wearing and tearing of seal ring;
4, simplified the structure of central air-charging and air-discharging system and reduced the hardware configuration of vehicle.
