Problems solved by technology

The relationship between the Rabinal car tire valve and the rotating sealed air chamber is one-way input. When measuring pressure, the high-pressure gas from the air chamber enters the car tire valve, but when the air pressure in the car tire valve is higher than the rotating sealed air chamber When the pressure is high, the airflow cannot reversely flow to the rotating sealed air chamber through the automobile tire valve, so when the automobile tire valve is used in the central inflation and deflation system, it can only be used for single-tire pressure measurement, and cannot be used for single-bridge pressure measurement.
For some manufacturers or users who want to simplify the structure and reduce the cost, it is impossible to use this kind of automobile tire valve for the system that requires single-axle or multi-axle tires to be controlled together.
The structural principle of the Rabinal car tire valve does not provide a basis for simplifying the system. Another problem with the Rabinal car tire valve is that there is a large deviation between the measured value of the tire pressure and the real value

Embodiment Construction

[0026] Further illustrate below in conjunction with accompanying drawing and embodiment:

[0027] aforementioned, such as figure 1 The automobile tire valve includes an I-shaped sealing ring 1, a valve body 2, an O-shaped sealing ring 3, an elastic inner card 4, a spring 5, a valve cover 6, a dust cap 7, a nut 8, a valve core 9, a diaphragm disc 10, Diaphragm 11;

[0028] The connection relationship is: from top to bottom, the dust cap 7 is installed on the top of the valve cover 6, the valve cover 6 and the valve body 2 are connected together by the elastic inner clip 4, and a diaphragm is sandwiched between the valve cover 6 and the valve body 2 11. Diaphragm 11 divides the entire valve body into upper and lower air chambers. The valve core 9 and nut 8 are screwed to fix the two diaphragm discs 10 on the upper and lower sides of the diaphragm 11. The spring 5 is located between the valve cover 6 and the diaphragm. The valve core 9 is pressed against the hole end of the inn...

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 [0001] The invention relates to an automobile tire inflation and deflation valve, in particular to an automobile tire valve for an off-road automobile tire central inflation and deflation system. Background technique [0002] Foreign countries believe that the automobile tire valve is the most critical component in the tire central inflation and deflation system. The improvement and development of the structure of foreign tire central inflation and deflation systems are almost all related to the changes of automobile tire valves. The structure, function and characteristics of the automobile tire valve not only determine the structure of the control device of the system, but also determine the sealing requirements of the rotating sealed air chamber and affect the wear speed of the sealing ring, and also determine the speed of inflation and deflation; It affects the reliability of the system tire pressure and the convenience of operation. [0003] Most of the...
