Abstract
Description
Technical Field
[0001] This invention relates to the field of tire technology, and more specifically, to a safe and runaway tire. Background Technology
[0002] Most car tires currently in use are tubeless tires. When a tire is punctured by a foreign object while the vehicle is traveling at high speed, a slight leak can cause the rim to wear down due to contact with the ground; a severe blowout can occur, leading to loss of vehicle control and serious driving safety issues. To enhance tire safety, it is necessary to design a safer run-flat tire. Summary of the Invention
[0003] The purpose of this invention is to provide a safe and runaway tire to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, the present invention provides the following technical solution: A safety explosion-proof tire includes a rim and a tire mounted on the rim. The tire has a platform layer, a nylon belt layer, a steel wire layer and an inner sealing layer from the outside to the inside. The tire contains a support assembly for connecting the inner wall of the tire and the outer wall of the rim. The support assembly includes a support ring with an annular groove on its outer wall. Each side of the groove has at least two limiting holes. The inner wall of the tire, facing the platform, has a thickened protrusion. The thickened protrusion is annular and fits the groove. Each side of the thickened protrusion has a limiting protrusion, which corresponds to and is sized to the limiting holes. The thickened protrusion contains an annular cavity containing sealant wrapped in a plastic film. When the thickened protrusion is punctured, the sealant seeps out to seal the puncture.
[0005] Preferably, the outer ring wall of the rim has raised edge rings on both sides, and a first ring groove is formed between the raised edge rings on both sides. The first ring groove is provided with a second ring groove on both sides. The inner ring wall of the support ring is provided with annular raised rings on both sides. The raised rings are adapted to the second ring grooves. When the raised rings are placed in the second ring grooves, the inner ring wall of the support ring abuts against the inner wall of the first ring groove.
[0006] Preferably, the support ring includes an integral first rubber part and a second rubber part, the thickness of the first rubber part is greater than the thickness of the second rubber part, the first rubber part is located in the outer ring portion of the support ring, and the second rubber part is located in the inner ring portion of the support ring.
[0007] Preferably, the groove is located on the first rubber part, the convex ring is located on the second rubber part, the second rubber part is provided with an air chamber, and an air inlet pipe is also provided that connects to the air chamber. The end of the air inlet pipe away from the second rubber part extends toward the rim, and the rim is provided with a through hole for the air inlet pipe to pass through.
[0008] Preferably, the rim is provided with a round hole, and an air injection pipe that communicates with the inside of the tire passes through the round hole.
[0009] Preferably, a hub is provided at the center of the inner ring of the rim, and the hub and the rim are connected by spokes.
[0010] Preferably, the wheel hub has multiple mounting holes.
[0011] Compared with the prior art, the beneficial effects of the present invention are: This safety run-flat tire features a thickened raised layer on the inside. When a foreign object punctures the tire tread, if the object is short, it will not directly puncture the tire. Even if a long object punctures the tire, the sealant in the thickened raised layer will seep out and seal the puncture site, thus effectively preventing tire blowouts.
[0012] This safety run-flat tire features a support component that provides excellent support when the tire leaks air, preventing the tire from being flattened and causing friction damage between the rim and the ground. Air can be introduced into the air chamber through the intake pipe, enhancing the overall support of the support ring. Even if the tire ruptures, the vehicle can still continue to move.

Detailed Implementation
[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0020] This invention provides a technical solution: A type of safe runaway tire, please refer to Figures 1-5 It includes a rim 11 and a tire 10 mounted on the rim 11. The tire 10 has a platform layer 100, a nylon belt layer 101, a steel wire layer 102, and an inner sealing layer 103 from the outside to the inside. In this application, the nylon belt layer 101 and the steel wire layer 102 extend from the platform of the tire 10 to both sides, which can enhance the overall toughness and strength of the tire 10. Even if the tire 10 leaks air, it can maintain the tire 10 as a whole from being easily flattened.
[0021] The tire 10 is equipped with a support component, which is used to connect the inner wall of the tire 10 and the outer wall of the rim 11 for support. The purpose of setting the support component is to provide good support when the tire 10 leaks air, so as to prevent the tire 10 from being flattened, which would cause the rim 11 to rub against the ground.
[0022] Specifically, the support assembly includes a support ring 3, which is circular in shape. The outer ring wall of the support ring 3 has an annular groove 300. The inner walls on both sides of the groove 300 have at least two limiting holes 301. The inner wall of the tire 10, facing the table surface, has a thickened protrusion 104. The thickened protrusion 104 is annular and fits the groove 300. The two sides of the thickened protrusion 104 have limiting protrusions 105. The limiting protrusions 105 correspond to the limiting holes 301 in position and are matched in size.
[0023] During installation, the groove 300 on the support ring 3 can be aligned with the thickened protrusion 104, and the position of the limiting hole 301 can be aligned with the position of the limiting protrusion 105. Then, the support ring 3 is pushed so that the thickened protrusion 104 is embedded in the groove 300, and the limiting protrusion 105 is embedded in the limiting hole 301.
[0024] To facilitate the insertion of the limiting protrusion 105 and the limiting hole 301, the upper and lower end faces of the limiting protrusion 105 are set as arc surfaces.
[0025] This application provides an annular cavity 106 within the thickened raised layer 104, and a sealant 20 wrapped in a plastic film is provided in the cavity 106. When the thickened raised layer 104 of the tire 10 is punctured, the sealant 20 seeps out to seal the puncture site, thereby effectively preventing the tire from bursting.
[0026] The outer ring wall of the rim 11 has raised edge rings 112 on both sides. The raised edge rings 112 and the rim 11 are integral structures. A first ring groove 113 is formed between the raised edge rings 112 on both sides. A second ring groove 114 is provided on both sides of the first ring groove 113. The inner ring wall of the support ring 3 is provided with annular protrusions 311 on both sides. The protrusions 311 are adapted to the second ring grooves 114. When the protrusions 311 are placed in the second ring grooves 114, the inner ring wall of the support ring 3 abuts against the inner wall of the first ring groove 113.
[0027] During installation, first connect the support ring 3 to the thickened convex layer 104, and then install the wheel rim 11.
[0028] Specifically, the support ring 3 includes an integral first rubber part 30 and a second rubber part 31. The thickness of the first rubber part 30 is greater than the thickness of the second rubber part 31. The first rubber part 30 is located in the outer ring of the support ring 3, and the second rubber part 31 is located in the inner ring of the support ring 3.
[0029] The groove 300 is located on the first rubber part 30, and the convex ring 311 is located on the second rubber part 31. The second rubber part 31 is provided with an air chamber 310 and an air inlet pipe 312 that communicates with the air chamber 310. The end of the air inlet pipe 312 away from the second rubber part 31 extends toward the rim 11. The rim 11 is provided with a through hole for the air inlet pipe 312 to pass through. Of course, a sealing structure (existing sealing technology) will be provided at the connection between the air inlet pipe 312 and the through hole on the rim 11.
[0030] Air can be introduced into the air chamber 310 through the air intake pipe 312, which can enhance the overall support force of the support ring 3, so that the vehicle can still continue to drive when the tire 10 is ruptured.
[0031] The rim 11 has a round hole through which an air injection pipe connects to the inside of the tire 10. A sealing structure (using existing sealing technology) is provided at the connection between the air injection pipe and the rim 11, allowing the tire 10 to be inflated easily through the air injection pipe.
[0032] Furthermore, valve stems (i.e. tire valve stems) are installed in both the intake manifold 312 and the air injection manifold. A hub 111 is provided at the center of the inner ring of the rim 11, and the hub 111 is connected to the rim 11 by spokes; the hub 111 is provided with multiple mounting holes 110.
