Embodiment Construction

[0008] The present invention will be further described below in conjunction with specific examples.

[0009] In the air retaining structure of the pneumatic tire of the present invention, several leak-proof film roots 2 are fixed on the inner wall of the crown part of the tire carcass 1, and a piece of leak-proof film 3 is uniformly connected to each leak-proof film root 2 , the connection between the leak-proof film root 2 and the leak-proof film 3 is preset at an obtuse angle, and all the leak-proof films 3 are tilted to the right; among the two adjacent leak-proof films 3, the leak-proof film 3 on the left is The right-hand end of the frame rides on the left-hand end of the leak-proof film 3 positioned on the right side.

[0010] The connecting part of the leak-proof film root 2 and the leak-proof film 3 is preset at 90-100°.

[0011] In the present invention, the connecting part of the leak-proof film root 2 and the leak-proof film 3 is preset at an obtuse angle, so that ...

Abstract

The invention relates to an air-captive structure for an inflatable tire. A plurality of leakproof film roots are fixed on the inner wall of the crown part of a tire body, a piece of leakproof film isintegrally connected to each leakproof film root, the connecting parts between the leakproof film roots and the leakproof films are preset at the obtuse angle, and all leakproof films are tipped to the right; and in every two adjacent leakproof films, the right end of the leakproof film on the left side is overlapped on the left end of the leakproof film on the right side. According to the air-captive structure for the inflatable tire, the problem that the inflatable tire cannot continue to run for a long time when being punctured and deflates is solved, and the safety performance of the tireis improved.

Description

technical field [0001] The invention relates to an air retaining structure of a pneumatic tire, which belongs to the technical field of pneumatic tire structures. Background technique [0002] Pneumatic tires are easy to be stuck with foreign objects during driving and cause tire leaks. When a leak is found, the tire pressure is too low and it is not suitable to continue driving, causing great trouble to the driver. How to continue driving in this situation? At present, there are mainly two methods. The common method is to provide self-sealing rubber in the tire. However, this method generates high heat and high cost, and requires secondary processing by tire manufacturers, which is time-consuming and labor-intensive. Another way is to design self-supporting tires, but the manufacturing cost is high and the driving comfort performance is poor. At present, there is an urgent need for a method with low cost and simple processing to solve this problem. Contents of the invent...
