Description

Technical Field

[0001] The invention relates to the field of tires and supporting parts, and more particularly to a support ring for supporting inside a tire. Background Art

[0002] Existing run-flat tires are in the following forms, and the shortcomings of each form are listed as follows:

[0003] Thick-walled sidewall tires: poor impact resistance and comfort when inflated, heavy tires, large rolling resistance data, it is difficult to reach the safety limit for large specifications, special processes and specific equipment are required for production, which is very complicated and inefficient; Internal support fixed bracket: affects tire installation, poor ability to adapt to different section heights of tires, high cost for the overall structure to bear large loads, excessive friction with the sidewall, easy to cause early damage, and very difficult to replace. Usually, only the entire tire can be replaced, making the maintenance cost too high, and it is also easy to rub and collide with other parts inside the tire, and even get stuck; Inner wall anti-leakage glue spraying form: the sidewall cannot be effectively protected, the size of the protective puncture is limited, it is not easy to spray evenly, the production is very complicated and inefficient. At present, run-flat tires generally have the characteristics of heavy weight, the need for additional components or the use of special wheels, which increases the unsprung mass of the vehicle, thereby affecting the vehicle's handling performance. When the tire is used to the point of needing to be replaced, the price of the run-flat tire will also be higher than that of ordinary tires. In addition, some structures of run-flat tires cannot be repaired after damage and can only be replaced, which increases the maintenance cost. As the tire wall becomes thicker, the shock absorption effect of the tire decreases, and in severe cases, the wheel hub may be deformed.

[0004] Therefore, it is necessary to provide a support ring for supporting inside a tire to overcome the above problems. Summary of the invention

[0005] The invention provides a bracket ring for inner support of a tire which has low cost, excellent performance, simple structure, simple installation and wide popularity.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is: a support ring for internal support of a tire, the support ring is formed by four support units that cooperate with each other to form a ring structure, the top of the support unit has a support surface, the top of the support unit converges toward the bottom, the convergent part is a support portion, and the support portion has a contact surface on the side away from the support surface. In this solution, the support surface is used to support the inner wall of the tire shoulder, the contact surface is used to fit and fix with the inner surface of the tire bead, and the support part is used to transmit the force between the support surface and the contact surface; a bracket ring is installed on the inner surface of the tire bead, and the bracket unit is processed in equal parts of the circumference, which solves the problem of fine-tuning the circumference and symmetrical balancing quality; and because the bracket unit is a split and independent type, it does not affect the production and efficiency of the tire, and it is just assembled with each other before use, which solves the problem of complex and difficult production of run-flat tires, low efficiency and high cost; and overcomes the problem that large-size run-flat tires cannot meet international standards, and truly solves the run-flat of all passenger vehicle tires after a leak; the contact surface of the bracket unit designed for the same tire size is the same, because the small arc on the inner surface of the bead is almost the same under the same tire size, so the adaptability of the contact surface will be greatly enhanced, that is, one or two bracket rings can be selected for the same tire size (with different bracket heights).

[0007] That is to say, the support ring described in the present invention is an annular structure formed by the mutual cooperation of four support units, and refers to a support ring installed on the inner surface of the tire bead. In fact, it is an integral support ring formed by the mutual cooperation of four separate support units in the tire bead, and then the integral support ring assembled in the tire is installed in a fixed position on the inner surface of the tire bead.

[0008] The top of the bracket unit in the present invention has a support surface, and the top of the bracket unit converges to the bottom, and the convergent part is a support portion, and the support portion has a contact surface on the side away from the support surface. It means that when the tire is deflated, the inner surface corresponding to the outer surface of the tire contacting the ground will directly contact the support surface at the top of the bracket unit, and then the force between the tire and the ground is sequentially transmitted through the inner surface corresponding to the outer surface, the support surface at the top of the bracket unit, the support portion of the bracket unit, the contact surface of the bracket unit, the inner surface of the tire bead of the contact surface, and the outer surface of the tire bead corresponding to the inner surface of the tire bead, and finally to the wheel hub in contact with the outer surface of the tire bead. In this way, the support of the inside of the tire is achieved when the tire is deflated, without the tire directly rolling on the wheel hub, causing the tire bead to derail and completely fall off and be damaged, and the vehicle to lose control.

[0009] In order to ensure that the assembly structure of the bracket ring is firm and widely popular, preferably, the bracket unit and the adjacent bracket units are fixedly connected by a mortise and tenon structure. In this solution, the assembly structure of the bracket ring is a mortise and tenon structure, which is firm and can be fine-tuned according to the size of the tire. It is widely popular, simple in structure, and easy to install. At the same time, it is a single support frame structure, so the production is simple and convenient.

[0010] In order to enhance the bearing capacity of the support ring and improve production efficiency, preferably, the support part is a support part of a bridge arch structure. The bridge arch structure is adopted, and the mechanics principle of the arch bridge is used to greatly improve the bearing capacity of the support ring; and the design of the bridge arch is conducive to more convenient, more efficient and better quality of the support unit during injection production, and the damage to the injection mold is small.

[0011] In order to ensure the high practicality and high applicability of the bracket ring, preferably, the bracket unit is a bracket unit made of nylon and carbon fiber. In this solution, the bracket unit material is nylon-66 and carbon fiber, and nylon-66 has the following excellent performance: high strength, good resilience, wear resistance, resistance to multiple deformations and fatigue resistance, good heat absorption, and carbon fiber has the following excellent performance: high temperature resistance, friction resistance, heat conduction and corrosion resistance. The various excellent properties of nylon-66 and carbon fiber make the bracket unit made of nylon-66 and carbon fiber highly practical and highly applicable.

[0012] In order to make the production of the bracket unit more convenient and improve the precision, preferably, the bracket unit is a bracket unit made by injection molding process. In this scheme, the bracket unit is made by injection molding process and is made separately, so it does not affect the production and production efficiency of the tire. It is just assembled with each other before use, which solves the problem that the original production process of run-flat tires is multiple, complicated, difficult, inefficient and costly, and the bracket unit has high production efficiency, good quality and high precision.

[0013] In order to ensure the stability of the support ring assembly structure, preferably, the contact surface has an adhesive layer formed by an adhesive. In this solution, after the support ring is subjected to force as a whole, it is transmitted to the arc surface of the tire and the contact surface through the support part. There is an adhesive layer on the surface to increase the adhesion, which can effectively ensure that the support ring slides down or shifts as a whole after being subjected to a certain vertical or lateral load, that is, the surface friction of the contact surface is greater than the downward force, and the support ring will not move in the direction of force as a whole or shift in the direction of the tire center line, ensuring the stability of the support ring structure during installation and operation.

[0014] Moreover, the contact surface is at a certain distance from the tire toe, and the distance is determined so as not to affect the installation and removal of the tire. After the support ring is installed, it will not affect the normal installation and removal of the tire. The support ring only contacts the tire bead when the tire is inflated. The support ring is fixed on the inner surface of the tire bead when the tire is inflated, and has no contact with other parts of the tire, so it does not affect the normal driving and original comfort performance of the tire.

[0015] Compared with the prior art, the present invention has the following beneficial effects: when the tire is kept in a normal inflation state, the comfort of the tire is consistent with that of an ordinary tire, thus solving the problem of poor comfort; it can effectively reduce the corresponding increased weight, which is helpful to reduce rolling resistance and fuel consumption, thus solving the original disadvantages of heavy weight and high fuel consumption; since it is a split bracket unit, it has strong adaptability to tires of the same size (one inch can use one or two bracket rings), thus solving the problem of the applicability of the bracket ring to tires of the same size but different specifications; it overcomes the problem that the run-flat of large-size tires cannot meet international standards, thus truly solving the problem of the run-flat of all passenger vehicle tires after a leak; since the bracket unit is made separately, it does not affect the manufacture and efficiency of the tire, and it is only assembled with each other before use, thus solving the problem of the manufacture of run-flat tires The problems of high complexity, difficulty, low efficiency and high cost are solved. Since the bracket unit is made by injection process, the precision is high and the circumference is equally divided, so the problems of fine-tuning the circumference and symmetrical balance quality are solved. The bracket ring can play the role of run-flat after the tire is punctured, so as to ensure that the vehicle does not lose control and drives safely to a reasonable position for necessary tire replacement. At the same time, it can meet the run-flat requirements of all passenger vehicles, and the installation is simple and convenient, with strong adaptability, and does not affect the traditional tire production process. When the bracket unit needs to be replaced, it only needs to be removed and replaced, and there is no need to replace the entire tire, thereby reducing the maintenance cost. Or after the tire is punctured, as long as the bracket unit is not damaged, it only needs to be removed and installed on the repaired tire or a new tire, thereby reducing the maintenance cost.

[0032] Preferred embodiment: In this embodiment, as Figure 1 As shown, the inner surfaces of both sides of the tire bead 4 are equipped with support rings, such as Figure 5 and Figure 6 As shown, the stent ring is composed of four stent units that cooperate with each other to form a ring structure, such as Figure 2 As shown, the assembly structure is a mortise and tenon structure. Figure 3 As shown, the support unit is a support unit adopting a bridge arch structure, such as Figure 1 As shown, the inner surfaces of both sides of the tire bead 4 are equipped with support rings assembled from bridge arch structure support units, such as Figure 4 As shown, when the tire 4 is leaking, the support surface 1 of the bracket unit supports the shoulder position, so that the tire 4 can continue to travel a certain distance before being replaced, and the support part 3 of the bracket unit is a support part 3 of a bridge arch structure. After the support surface 1 is subjected to force, it is transmitted to the contact surface 2 through the support part 3, and the contact surface 2 and the contact surface of the inner surface of the tire 4 bead are coated with adhesive, which can effectively ensure that the bracket unit will not move in the direction of force or shift in the direction of the center line of the tire 4 as a whole after being subjected to a certain vertical or lateral load, that is, to ensure that the bracket ring can support the tire 4, so that the tire 4 can continue to travel normally for a certain distance. In actual applications, according to actual needs, the bracket unit of the bridge arch structure is selected to be assembled into a corresponding bracket ring.

[0033] A method for installing a support ring for internal support of a tire comprises the following steps:

[0034] Step a, prepare a tire 4 outer tire;

[0035] Step b, taking out the first bracket unit 5a of the first bracket ring, and applying adhesive on the contact surface between the contact surface 2 and the inner surface of the bead of the tire 4;

[0036] Step c: fitting the contact surface 2 to the inner surface of the tire bead 4, and making a certain distance between the contact surface 2 and the bead toe, the distance being such that it does not affect the installation and removal of the tire 4;

[0037] In step d, take out the second bracket unit 5b of the first bracket ring, the third bracket unit 5c of the first bracket ring, and the fourth bracket unit 5d of the first bracket ring, and repeat the installation operation of the first bracket unit 5a of the first bracket ring, so that the four bracket units are sequentially matched and assembled into a ring-shaped first bracket ring, that is, the first bracket ring is installed on one side of the tire 4 bead.

[0038] In step e, take out the first bracket unit 6a, the second bracket unit 6b, the third bracket unit 6c and the fourth bracket unit 6d of the second bracket ring of the second bracket ring, and refer to the installation steps of the first bracket ring to make the four bracket units of the second bracket ring cooperate and assemble into a ring-shaped second bracket ring in sequence, that is, install the second bracket ring on the other side of the tire 4 bead.

[0039] There is a certain distance between the contact surface 2 and the tire toe 4, and the distance is determined so as not to affect the installation and removal of the tire 4. After the support ring is installed, it will not affect the normal installation and removal of the tire 4. The support ring only contacts the bead of the tire 4 when the tire 4 is inflated. The support ring is fixed on the inner surface of the bead when the tire 4 is inflated, and has no contact with other parts of the tire 4, so it does not affect the normal driving and comfort performance of the tire 4.

[0040] In order to further enhance the structural stability of the bracket ring, the vertically engaged mortise and tenon structure may be designed as a 30-degree inclined mortise and tenon structure.

[0041] In the present invention, the bracket unit of the bracket ring is an independently produced split independent bracket unit, which only needs to be installed with the tire 4 before use. Therefore, in practical applications, according to different needs and different specifications, models and sizes of the tire 4, a bracket unit with a bridge arch structure can be selected, and brackets of different heights can be selected and assembled into a bracket ring, which is suitable for the run-flat requirements of all passenger vehicles.

[0042] The above-described embodiments are used to illustrate the present invention, not to limit the present invention, so changes in the exemplified values ​​or replacement of equivalent elements should still fall within the scope of the present invention.

[0043] The above detailed description will make it clear to those skilled in the art that the present invention can indeed achieve the aforementioned objectives and has complied with the provisions of the Patent Law, and a patent application is now filed.
