Reinforced anti-puncture run-flat composite tire

Abstract

The invention discloses a reinforced anti-puncture run-flat composite tire which comprises an outer tire, an airtight inner rubber layer, an airtight rubber spacing, a reinforced foamed solid inner tire, an annular rubber pipe and an independent air-filled inner tire, wherein the airtight inner rubber layer is adhered to the inner wall of the outer tire; the airtight rubber spacing is transversely arranged in the middle of the airtight inner rubber layer; the space between the upper part of the airtight rubber spacing and the lower part of a hub is an air chamber; the independent air-filled inner tire is arranged in the air chamber; the reinforced foamed solid inner tire is arranged below the airtight rubber spacing; the annular rubber pipe is longitudinally arranged in the reinforced foamed solid inner tire; the reinforced foamed solid inner tire and the annular rubber pipe are filled with elastic foam materials. Compared with the prior art, the reinforced anti-puncture anti-explosion composite tire is simple in structure, easy to process, anti-puncture and run-flat; a tire after air leakage is the same as a tire with reduced air, so that normal driving of vehicles is completely not influenced; the composite tire is safe and durable, and has very good promotion and application values.

Description

technical field [0001] The invention relates to the technical field of transportation, in particular to a reinforced puncture-proof and explosion-proof composite tire. Background technique [0002] Tires in the prior art are generally divided into pneumatic tires and non-pneumatic tires. Although non-pneumatic tires are used without the inflation process and are more convenient to use, the tires have thicker sidewalls and even solid tires, so the elasticity is insufficient and the cushioning effect is low. Poor, poor shock absorption performance. For this reason, air-free tires still can not completely replace pneumatic tires at present. [0003] However, pneumatic hollow tires also have disadvantages: [0004] 1. When the inflated hollow tire is in the driving process of the vehicle, once the tire wall is punctured by a sharp object or a sudden tire blowout occurs, the gas in the tire will leak quickly and cause the vehicle to lose stability, which is prone to traffic ac...

AI Technical Summary

Problems solved by technology

[0004] 1. When the inflated hollow tire is in the driving process of the vehicle, once the tire wall is punctured by a sharp object or a sudden tire blowout occurs, the gas in the tire will leak quickly and cause the vehicle to lose stability, which is prone to traffic accidents and cause vehicle damage and even personal safety;

[0005] 2. If the pneumatic tire is over-inflated, the vehicle will jump due to excessive tire pressure during driving; if it is under-inflated, it will easily cause local overheating and affect the service life of the tire

[0006] The deficiencies that existing technology tire exists, also do not have good solution at present
