Blowout-proof tire

Abstract

The invention relates to a tire, belongs to the technical field of automobile tires, and in particular to a compound type blowout-proof tire. The blowout-proof tire comprises a wheel hub and a tire body, the tire body is arranged on the wheel hub, and the tire body comprises an inner tube-free radial tire and a blowout-proof auxiliary tube, wherein the radial tire is in the outer layer, the auxiliary tube is arranged in the inner chamber of the radial tire and fixed on the wheel hub through air inflation. The auxiliary tube comprises a ring gasket, an air inflation inner tube and a ring strengthening wheel arch trim, wherein the ring gasket is clung to the inner wall of the wheel hub, the ring strengthening wheel arch trim wraps the periphery of the air inflation inner tube; the auxiliary tube has no contact with the inner wall of the radial tire, the size of the space between the auxiliary tire and the radial tire enables the outer tire and the inner tube do not contact with each other under a normal driving condition. The blowout-proof tire provided by the invention has the advantages that 1, the sudden bearing capability of the tire can be strengthened to prevent the tire from blowout; 2, a vehicle can be enabled to keep running relatively smoothly even if the outer tire blows out or releases pressure; 3, the blowout-proof tire is easy to install, and convenient to popularize.

Description

technical field [0001] The utility model relates to tires, belongs to the technical field of automobile tires, in particular to a composite type explosion-proof tire. Background technique [0002] Tire blowout is a very serious safety accident, especially on the expressway, which will cause the vehicle to lose control, roll over and cause traffic accidents; therefore, a kind of run-flat tire is needed. Most of the current run-proof tires are made by enlarging the tire The thickness and hardness of the tire wall are used to slow down the change of the tire thickness after the vehicle blows out. At present, there are solid tires designed to prevent explosions, but these solid tires have poor shock absorption and are not suitable for high-speed driving. There is also patent report to occur the composite run-flat tire, but there is no marketization. Therefore, be badly in need of a kind of novel run-flat tire with simple structure, low cost, easy installation. Contents of the...
