However, since the air pressure of the hollow layer can be used for inflating the small air bags through the one-way valves, once the pressure of each small air bag is reduced during air leakage, the air in the hollow layer can be automatically inflated to the small air bags under the action of the pressure until the air in the hollow layer is discharged to the normal pressure through the small air bags, and the tire pressure of other small air bags is still kept in a high-pressure state, so that the air pressure of the hollow layer and the small air bags is unbalanced, and great influence is caused on the balance and safety of the vehicle in running. If set up to the mode of aerifing alone small air bag layer and hollow layer, need set up a plurality of inflation valves, still can't keep the tire pressure balance of small air bag layer and hollow layer when aerifing respectively.

The present invention will be further described with reference to the following embodiments. Wherein the showings are for the purpose of illustration only and are shown by way of illustration only and not in actual form, and are not to be construed as limiting the present patent; to better illustrate the embodiments of the present invention, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of an actual product; it will be understood by those skilled in the art that certain well-known structures in the drawings and descriptions thereof may be omitted.
example 1
The embodiment provides a multi-block safety tire pressure balancing method, which comprises the following steps:
Firstly, arranging an air bag layer 16 and a hollow layer 4 on a tire; the air bag layer 16 is arranged on the outer ring of the tire and is composed of a plurality of independent small air bags 18;
In the first step, the air bag layer comprises a plurality of small air bags with different shapes and sizes. .
Secondly, arranging an air pressure balance layer 3 which can inflate the air bag layer 16 and the hollow layer 4 in a single direction between the two layers;
Thirdly, inflating the air pressure balancing layer 3 to improve the air pressure of the layer;
The pressure of the air pressure to be inflated into the air pressure equalizing layer 3 in the third step is usually controlled within the range of 0.1 to 1.2 MPa.
fourthly, the air in the air pressure balance layer 3 inflates the small air bags 18 and the hollow layer 4 of the air bag layer 16 in a single direction, so that the air pressure of the air pressure balance layer 3, the air bag layer 16 and the hollow layer 4 is kept consistent.
In the fourth step, a one-way valve 20 is arranged between each small air bag 18 and the hollow layer 4 of the air pressure balance layer 3 and the air bag layer 16, and the air in the air pressure balance layer 3 automatically inflates each small air bag 18 and the hollow layer 4 of the air bag layer 16 through the one-way valve 20 until the air pressures of the three layers are consistent.
A multi-block run-flat tire including the air bag layer 16, the air pressure equalizing layer 3, and the hollow layer 4 is previously constructed. The multi-block safety tire comprises an outer tire 15, an air bag layer 16, an air pressure balance layer 3, a hollow layer 4 and a metal hub 17 which are arranged in sequence from outside to inside. The outer tire 15 in this embodiment is of an existing radial tire structure, and different radial tire products have different lengths in various performances, but can be applied to the tire by slightly changing the process. The tire has safety performance, the original performance of the tire is hardly influenced, and various advantages of the original tire are reserved. Because the tyre is specially provided with the high-safety air bag layer 16, the puncture-proof grade of the outer tyre can be properly reduced, the radial tyre with a multilayer structure is adjusted, the internal structure of 1-2 layers is reduced, the production cost is reduced on the basis of not influencing the safety performance, and the weight of the tyre is lightened.
The air bag layer 16 comprises a plurality of small air bags 18, and is formed by integrally injection molding by using a high-air-tightness butyl rubber material, or can be formed by bonding and splicing a plurality of small air bags 18. Wherein the number of the small air bags 18 is from dozens to dozens, and the number of the small air bags 18 is adjusted according to the requirements of different working environments on the supporting force of the tire. The shape of the small cells 18 of the cell layer 16 may be a cylinder, a pentagonal prism, a hexagonal prism, or other types of polyhedrons, wherein each of the small cells 18 may be the same size and the same shape; or different sizes and same shapes; can be in different shapes and same size; or may be different in size and shape. The small air bags 18 are erected on the outer surface of the air pressure balancing layer 3 along the radial direction of the tire, namely, the height of the small air bags 18 is parallel to the radius of the tire. The whole air bag layer 16 is in a honeycomb shape, so that the compactness of the structure is enhanced, and the supporting force of the air bag layer 16 is improved.
The air pressure balancing layer 3 is provided with an air charging and discharging valve 19 connected with the air pressure balancing layer, and the air charging and discharging valve 19 is used for charging air into the air pressure balancing layer 3 from the outside or discharging air in the air pressure balancing layer; the air pressure balancing layer 3 is also provided with a one-way valve 20 connected with each small air bag 18 and the hollow layer 4, and the one-way valve is used for the air pressure balancing layer 3 to inflate each small air bag 18 and the hollow layer 4 in a one-way mode. The air pressure balance layer 3 is also provided with a tire pressure monitoring device for detecting the pressure intensity in the tire.
The structure of the hollow layer 4 is basically the same as that of a single inflation cavity of the existing tire without an inner tube, but the difference is that the volume of the hollow layer 4 is greatly reduced compared with that of the single inflation cavity of the conventional tire because the multi-block airbag layer 16 is additionally arranged. The hollow layer 4 is provided with an exhaust valve for exhausting gas in the hollow layer when the tire pressure is too high.
The inflating device inflates the air pressure balance layer 3 through the inflating and deflating valve 19, the air pressure balance layer 3 inflates the small air bags 18 of the air bag layer 16 and the hollow layer 4 through the one-way valves 20 respectively, after inflation is completed, the air pressures of the air bag layer 16, the air pressure balance layer 3 and the hollow layer 4 are kept consistent, and the tire mainly works by the supporting force provided by the inflated air bag layer 16, the air pressure balance layer 3 and the hollow layer 4 together. The air pressure in the tire is detected by the tire pressure monitoring device, so that the control range of the air pressure in the air pressure balancing layer 3 is 0.1-1.2 MPa. When the tire is at atmospheric pressure, i.e., when the tire is not being inflated, the tire operates primarily with the support provided by the individual small cells 18 of the cell layer 16. When the air pressure in the tire is too high, the air in the air pressure balance layer 3 can be discharged through the air charging and discharging valve 19, and the air in the hollow layer can also be discharged through the air discharging valve, so that the tire pressure in the tire can be adjusted.
By additionally arranging the air pressure balance layer 3, the hollow layer 4 is prevented from being directly connected with the air bag layer 16, and the air tightness of the hollow layer 4 is improved; while avoiding deflation of the hollow core 4 in direct communication therewith due to breakage of the individual cells 18 of the cell layer 16. The air pressure balance layer 3 can inflate the hollow layer 4 in real time through the check valve 20, and can inflate the hollow layer 4 when the hollow layer 4 is damaged, so that the situation that the air pressure in the hollow layer 4 is sharply reduced is avoided. The tire is provided with the air bag layer 16, when the crown of the outer tire 15 and the individual small air bags 18 are punctured by foreign matters, the structures of the rest small air bags 18 and the hollow layer 4 are not damaged, so that the integral supporting force of the tire is not influenced, and the tire can be normally used. When the hollow layer 4 is damaged, the air bag layer 16 can provide a certain supporting force, and the tire cannot be completely out of work. Meanwhile, the air bag layer 16 avoids the phenomenon that the air in the tire of the traditional tire is reduced, and the supporting force of four wheels is too different, so that the vehicle loses balance.
Example 2
As shown in fig. 2, the present embodiment is different from embodiment 1 in that an inflation and deflation valve 19 is provided, which comprises a valve 1 and an outer air duct 2 arranged outside the valve 1, wherein the valve 1 is connected with an air pressure balancing layer 3 for adjusting the air pressure of the air pressure balancing layer 3; the outer air duct 2 is communicated with the hollow layer 4 and is used for adjusting the air pressure of the hollow layer 4; the outer gas channel 2 is provided with an isolating device 5 for isolating the hollow layer 4 from communicating with the outside, and the isolating device 5 is opened to release the gas in the hollow layer 4.
The valve 1 generally comprises a valve body and a valve core; the valve core is positioned in the valve body and is mainly used for realizing air intake of the tire and preventing air leakage of the tire; the outer wall of the valve 1 is provided with threads which can be used for connecting an inflating device and can also be used for installing a valve cap. The valve 1 may also be an existing american valve or french valve structure.
The valve 1 is provided with a concentric outer sleeve 7 on the outside, and the passage between the outer sleeve 77 and the outer wall of the valve 1 forms an outer air duct 2. An air outlet which can lead the outer air duct 2 to be communicated with the outside is arranged at the connecting part of the outer sleeve 7 and the inflating valve 1. An isolating device 5 is arranged between the outer casing 7 and the inflating valve 1, the isolating device 5 comprises a spring sleeved outside the inflating valve 1 and an isolating valve 9 connected with the spring, and the isolating valve 9 is used for blocking an air outlet of a connecting part of the outer casing 7 and the inflating valve 1 so as to control the communication between the hollow layer 4 and the outside. The outer casing 7 is provided with a sealing gasket 10 at the position of being tightly pressed and connected with the isolation valve 9, the air tightness of the isolation valve 9 is enhanced, the isolation valve 9 is provided with a thimble 11 extending out of the air outlet, when the air in the hollow layer 4 needs to be discharged, the thimble 11 is pressed, the isolation valve 9 is separated from the sealing gasket 10, and therefore the hollow layer 4 is communicated with the outside.
The inflating device is fixedly connected with the inflating valve 1 through threads, and meanwhile, the valve core is pushed away from the original position, so that air can enter the air pressure balance layer 3 of the tire through the part where the valve core is separated from the inflating valve body. After the inflation is finished and the inflation device is taken away, the valve inside returns to the original position under the combined action of the pressure in the tire and the elastic device 6, and the air pressure balance layer 3 is isolated from being communicated with the outside. When the tire pressure monitoring device finds that the air pressure in the tire is too high and needs to deflate the tire, the valve inside can be ejected away from the original position again through an external device, so that the air pressure balance layer 3 is communicated with the outside, and the air pressure in the layer is higher than the outside air pressure, so that the air leakage operation can be completed. When the hollow layer 4 of the tire needs to be depressurized and deflated, an acting force is externally given to the ejector pin 11 connected with the isolation valve 9, the isolation valve 9 is ejected away from the original position, so that the outer air duct 2 is communicated with the outside through the air outlet, and the outer sleeve 7 is provided with the exhaust hole 8, so that the air of the hollow layer 4 can enter the outer sleeve 7 through the exhaust hole 8 and then be exhausted to the outside through the air outlet. When the air leakage of the hollow layer 4 is completed, the acting force applied to the thimble 11 is removed, so that the isolation valve 9 is pressed with the sealing washer 10 of the outer-layer sleeve 7 again under the action of the spring and the internal pressure of the outer channel 2 to block the air outlet, and the outer channel 2 is isolated from being communicated with the outside.
The inflation and deflation valve 19 can select a proper deflation mode according to the pressure in the tire, and when the air pressure in the air pressure balance layer 3 needs to be deflated, the inflating valve 1 can be used for relieving the pressure; when the air pressure of the hollow layer 4 needs to be released, the outer air channel 2 can be used for releasing the pressure; when the air pressure range needs to be adjusted to be small, the air valve 1 or the outer air duct 2 can be independently used for pressure relief; when the range of the air pressure needing to be adjusted is large, the air valve 1 and the outer air duct 2 can be used for simultaneously releasing the pressure. The flexibility of the pressure relief mode is increased, and the pressure relief efficiency is improved.
