Description

Technical Field

[0001] The invention relates to the field of wheels, and in particular to a tire explosion-proof and tire air leakage-proof wheel assembly. Background Art

[0002] Wheels are the main components that support vehicles, aircraft and mobile equipment using tires. Vehicles, aircraft and mobile equipment using tires have gradually become the main means of daily travel and cargo transportation for people. However, the problem of tire driving safety has never been effectively solved. When a tire of a vehicle, aircraft or other mobile equipment using tires bursts or leaks, the tire will immediately lose its support ability, causing the vehicle, aircraft and other mobile equipment using tires to lose balance and cause serious accidents, posing a major threat to personal safety and causing significant losses to personal wealth. According to statistics, more than 40% of highway traffic accidents in China are currently caused by tires, among which tire blowouts are the most serious, accounting for 70%. Therefore, how to prevent tire blowouts and tire leaks has become an urgent need for people, especially ordinary tires.

[0003] To this end, people have also proposed some solutions, such as: explosion-proof tires, explosion-proof wheels (or hubs) and explosion-proof rims, including some solutions that use air suspension technology to solve the imbalance of the vehicle caused by tire blowout. These solutions have not yet completely solved the problem fundamentally. For example, the utility model patent disclosure (authorization announcement number) CN209274284U in the Chinese patent literature discloses "explosion-proof hub, explosion-proof tire and mobile tool", the utility model patent disclosure (authorization announcement number) CN201158279Y in the Chinese patent literature discloses "explosion-proof rim", etc., which are arranged between the tire and the wheel. The technical solutions for the internal space between the tire and the wheel all have a common major defect: ordinary technicians can understand that all the "devices" that play the role of explosion-proofing must have a certain gap with the tire, and the gap cannot be too large, otherwise it will lose its function. That is to say, the maximum outer diameter of the integrated "explosion-proof device" in all the current technical solutions set in the internal space between the tire and the wheel is much larger than the diameter of the tire through-hole, and it is impossible to install it in the internal space of the tire, let alone effectively fix it with the wheel. Therefore, all the currently disclosed technical solutions for the integrated explosion-proofing set in the internal space between the tire and the wheel are invalid technical solutions.

[0004] Here, we will not discuss each of the documents one by one. Summary of the invention

[0005] In view of the above-mentioned defects and in order to solve the shortcomings in the prior art, the present invention provides a tire explosion-proof and tire air leakage-proof wheel assembly without changing some general technologies of the existing wheels. The present invention solves the problem that after a tire explosion or tire air leakage, the tire will immediately lose its supporting ability, causing vehicles, airplanes and other mobile equipment using tires to lose balance. Ordinary tires can also be used with confidence, and the service life of the tires is extended. At the same time, the waste of resources is reduced, and the wheel assembly is safe and reliable, and easy to disassemble and replace.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a run-flat tire and tire air leakage prevention wheel assembly, comprising a wheel body, a run-flat tire assembly and a tire, the wheel body comprising a hub, a spoke and a rim, the hub and the rim are fixedly connected by the spoke, the rim is respectively provided with a valve and a monitoring device, the tire is installed and supported in both sides of the rim, and the run-flat tire assembly is arranged in the internal space between the rim and the tire; the inner end and the outer end of the run-flat tire assembly are both circular, and a certain gap is arranged between the outer periphery of the run-flat tire assembly and the tire; the rim comprises a rim A and a rim B, the rim A is fixedly connected to the spoke, a part of the outer end surface of the bottom of the rim B is arranged as a flat and smooth surface, the inner end of the run-flat tire assembly is fixed on the flat and smooth surface of the bottom of the rim B, the bottom edges of the rim A and the rim B are respectively provided with flanges, the flanges tightly fix the rim B, the run-flat tire assembly and the rim A together by bolts, and a sealing structure is arranged in the upper position of the bolt holes of the flanges of the rim A and the rim B.

[0007] Furthermore, the run-flat tire assembly is configured to consist of a plurality of connecting blocks A and connecting blocks B, and the connecting block B is preferably one.

[0008] Furthermore, the connecting block A and the connecting block B are configured for directional installation and directional removal, the installation direction is the outer end of the tire, and the removal direction is the center of the tire. The connecting block A and the connecting block B are preferably fixedly connected to each other in a dovetail groove structure.

[0009] Furthermore, the width of the connecting block A and the connecting block B is smaller than the diameter of the tire through hole.

[0010] Furthermore, the inner arc length of the connecting block A is smaller than the outer arc length.

[0011] Furthermore, the connection block B is configured such that the inner arc length is equal to or greater than the outer arc length, and a mark is provided on the flange portion of the rim A or rim B corresponding thereto.

[0012] Furthermore, the explosion-proof tire assembly includes a supporting component, a secondary rim and an elastomer, the outer end of the supporting component is fixedly connected to the secondary rim, the inner end of the supporting component is set as a circular hole, and is fixed to the flat and smooth surface of the bottom of the rim B through the circular hole, the elastomer is installed on both sides of the secondary rim, and a certain gap is set between the outer end of the elastomer and the tire.

[0016] 2. The explosion-proof tire assembly is safe and reliable, and easy to disassemble and replace.

[0017] 3. When the tire of a moving vehicle, aircraft or other mobile equipment using tires suddenly bursts or loses air, the distance between the outside of the tire and the ground decreases, and at the same time, the inside of the tire contacts the elastomer on the secondary rim. The elastomer supports the tire, thus solving the problem of vehicles, aircraft or other mobile equipment using tires losing balance and causing accidents due to the tire's immediate loss of support capacity.

[0018] 4. After the elastomer on the run-flat tire assembly contacts the tire, the elastomer relies on the friction with the tire, and the outside of the tire maintains effective contact with the ground, so the tire can still maintain normal driving of the vehicle.

[0019] 5. The advantages of the elastomer on the explosion-proof tire component are wear resistance and no fear of puncture.

[0020] 6. Ordinary tires can be used with confidence without worrying about tire blowouts or tire air leakage causing imbalance in vehicles, aircraft, and other mobile equipment using tires, thus reducing the occurrence of accidents caused by tire problems.

[0021] 7. It extends the service life of tires, especially ordinary tires. As long as the tires are not blown, deflated, or damaged, they can be used normally, which reduces the cost of using the vehicle and reduces the waste of resources. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The specific implementation manner of the present invention is described below in conjunction with the accompanying drawings. It should be noted that, generally speaking, a wheel body includes a hub, spokes, and a rim. Due to the integration process of the hub, spokes, and rim, many people also regard the wheel and the hub as the same object. For example, the term "hub" described in the utility model patent disclosure (authorization announcement number) CN209274284U in the Chinese patent literature is the same as the term "wheel" generally used; for the convenience of explaining the technical solution, the term "wheel" in this article and the "hub" commonly known as many people are the same object; unless otherwise defined, all technical and scientific terms used in this article have the same meaning as those generally understood by technicians in the technical field of the present invention; the terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments, and are not intended to limit the present invention.

[0026] like Figure 1 , Figure 2 As shown, a run-flat tire and tire air leakage proof wheel assembly is composed of a wheel body 1, a run-flat tire assembly 2 and a tire 3. On the basis of not changing some general technologies of the existing wheel body 1, the wheel body 1 includes a hub 11, a spoke 12 and a rim 13. The hub 11 and the rim 13 are fixedly connected by the spoke 12. The rim 13 is respectively provided with a valve and a monitoring device. The monitoring device can detect the air pressure or temperature in the tire 3 and predict the occurrence of a run-flat tire or tire air leakage in advance; the tire 3 is installed and supported on both sides of the rim 13, and the run-flat tire assembly 2 is arranged in the internal space between the rim 13 and the tire 3, which does not affect the appearance of the entire wheel assembly. The inner and outer ends of the run-flat tire assembly 2 are both circular, and a certain gap is set between the outer periphery of the run-flat tire assembly 2 and the tire 3, and the gap range is based on the safe and smooth transition between the tire 3 and the run-flat tire assembly 2 after a run-flat or deflation.

[0027] The rim 13 includes a rim A 131 and a rim B 132. The rim A 131 is fixedly connected to the spoke 12. A portion of the outer end surface of the bottom of the rim B 132 is set to a flat and smooth surface. The inner end of the run-flat tire assembly 2 is fixed on the flat and smooth surface of the bottom of the rim B 132, which increases the support area of ​​the run-flat tire assembly 2 and facilitates installation, fixing and positioning. The bottom edges of the rim A 131 and the rim B 132 are respectively provided with flanges 133. The flanges 133 tightly fix the rim B 132, the run-flat tire assembly 2 and the rim A 131 together through bolts, which facilitates the installation and disassembly of the run-flat tire assembly 2 and the tire 3 and facilitates the maintenance and replacement of components. In addition, a sealing structure 134 is provided in the upper position of the bolt holes of the flanges of the rim A 131 and the rim B 132 to prevent air leakage at the flange 133.

[0028] The run-flat tire assembly 2 is configured to be composed of a plurality of connection blocks A 20 and a connection block B 21, and the connection block B 21 is preferably one, which is convenient for installation and free disassembly.

[0029] The connecting block A 20 and the connecting block B 21 are configured for directional installation and directional removal, wherein the installation direction is the outer end of the tire 3, and the removal direction is the center of the tire 3. The connecting block A 20 and the connecting block B 21 are preferably fixedly connected to each other in a dovetail groove structure, which is convenient for fixed installation and removal.

[0030] The width of the connecting block A 20 and the connecting block B 21 is smaller than the diameter of the through hole of the tire 3 . By setting it in this way, the connecting block A 20 and the connecting block B 21 can be installed in the inner space of the tire 3 .

[0031] The inner arc length of the connecting block A 20 is smaller than the outer arc length, which facilitates assembly.

[0032] The connecting block B 21 is configured such that the inner arc length is equal to or greater than the outer arc length. By configuring in this way, the connecting block A 20 and the connecting block B 21 are assembled into a complete fixed run-flat tire assembly 2 and installed into the inner space of the tire 3 .

[0033] During the assembly process of the connection block B 21 and multiple connection blocks A 20, the connection blocks A 20 are first installed one by one from the through hole of the tire 3 into the internal space of the tire 3, and then the connection block B 21 is set as the last one to be assembled and fixed with two adjacent connection blocks A 20; the connection block B 21 is marked at the flange 133 of the corresponding rim A 131 or rim B 132 to facilitate disassembly; when replacing the tire 3, the connection block B 21 is first disassembled, and then the other connection blocks A 20 are disassembled, so that the entire run-flat tire assembly 2 is disassembled from the tire 3.

[0034] The run-flat tire assembly 2 comprises a supporting component 22, a secondary rim 23 and an elastomer 24. The outer end of the supporting component 22 is fixedly connected to the secondary rim 23, preferably in an integrated fixed connection. The inner end thereof is provided with a circular hole, and is fixed to the flat and smooth surface of the bottom of the rim B 132 through the circular hole. Elastomers 24 are installed on both sides of the secondary rim 23. The elastomer 24 is used to buffer the impact force transmitted by the ground to the run-flat tire assembly 2 after the tire 3 bursts or deflates, support the balance of the wheel assembly, and further improve the safety performance. A certain gap is provided between the outer end of the elastomer 24 and the tire 3, and the gap is based on not hindering the normal installation of the tire 3 and the rim 13, and the gap is set to ensure that after the tire 3 bursts or the tire air leaks, the vehicle, airplane and other mobile equipment using the tire 3 will not lose balance.

[0035] A stop structure 135 is provided at the position where the inner end of the support component 22 contacts the rim A 131 or the rim B 132. The stop structure 135 is preferably a convex-concave matching structure, so that the support component 22 is firmly installed between the rim A 131 and the rim B 132, and at the same time prevents the run-flat tire assembly 2 from moving radially under the action of force.

[0036] The shape of the outer end of the elastomer 24 is the same as the shape of the top end of the tire 3, so that after the tire 3 has a blowout or tire air leaks, the outer end of the elastomer 24 is basically consistent with the contact surface inside the tire 3, preventing the friction between the elastomer 24 and the tire 3 from being reduced and slipping during driving after the tire 3 has a blowout or tire air leaks. The elastomer 24 is preferably a solid tire. The advantages of a solid tire are wear resistance and no fear of puncture. The solid tire ensures that after the tire 3 has a blowout or tire air leaks, the solid tire reduces the distance between the entire wheel assembly and the ground, and the solid tire supports the effective contact between the tire 3 and the ground, achieving a smooth transition between the tire 3 and the solid tire, maintaining the balance of vehicles, aircraft and other mobile equipment using tires, so that vehicles, aircraft and other mobile equipment using tires can travel normally and safely.

[0037] The area of ​​the run-flat tire assembly 2 is set to minimize the internal space between the tire 3 and the rim 13 on the basis of ensuring a reasonable tire pressure and air storage capacity of the tire 3.

[0038] The specific working process of the embodiment of the present invention is as follows: first, all the connecting blocks A 20 are assembled into the tire 3, and then the connecting block B 21 is installed in the internal space of the tire 3 and assembled together with the connecting block A 20 to assemble a complete fixed run-flat tire assembly 2, and then the run-flat tire assembly 2 and the tire 3 are installed on the rim B 132 together, and then the stop structure 135 of the rim A 131 corresponding to the contact part of the support component 22 is matched to fix and lock the entire run-flat tire assembly 2, and the rim A 131 and the rim B 132 are fixed together with the flange 133 using bolts to complete the assembly of the entire run-flat tire and tire air leakage prevention wheel assembly.

[0039] The normal working state is: the wheel body 1 and the tire 3 support the outside of the tire 3 to contact the ground through a certain air pressure, the elastomer 24 of the run-flat tire assembly 2 is preferably a solid tire (Note: the subsequent description of the elastomer 24 is discussed with solid tires), and a certain gap is set between the outer periphery of the solid tire and the inside of the tire 3, and the gap setting ensures that after the tire 3 bursts or the tire air leaks, the vehicle, airplane and other mobile equipment using the tire 3 will not lose balance, and the solid tire reduces the distance between the wheel body 1 as a whole and the ground; vehicles, airplanes and other mobile equipment using the tire 3 travel normally under the support of the tire 3, and when the tire 3 bursts or the tire air leaks, the gravity guide of the vehicle, airplane and other mobile equipment using the tire 3 The inner end of the tire 3 quickly contacts the outer end of the solid tire, and the solid tire quickly supports the tire 3 to contact the ground. The contact between the solid tire and the tire 3 realizes the balance and smooth transition of supporting vehicles, airplanes and other mobile equipment using the tire 3. Since the contact surface between the outer end of the solid tire and the inner end of the tire 3 is basically consistent, the friction between the solid tire and the tire 3 is reduced and the vehicles, airplanes and other mobile equipment using the tire 3 are prevented from slipping during driving after the tire 3 has a blowout or tire air leakage, thereby maintaining the basic balance of the vehicles, airplanes and other mobile equipment using the tire 3, and also ensuring that the vehicles, airplanes and other mobile equipment using the tire can continue to drive normally and safely.

[0040] Finally, it should be noted that the above is only a specific embodiment of the present invention, and the embodiment is only used to illustrate the technical solution of the present invention, rather than to limit other forms. Although the present invention has been described in detail with reference to the above embodiment, a person skilled in the art should understand that the technical solution described in the above embodiment can still be modified, or part or all of the technical features can be replaced by equivalents, and these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the present invention.
