Description

Elastic unit integral type intelligent safety tire and manufacturing method thereof

The invention belongs to the technical field of tires, and in particular relates to an elastic unit integral type intelligent safety tire capable of explosion-proof, anti-mite and gas-deficient maintenance and a manufacturing method thereof. Background technique

With the rapid development of the transportation industry, people's requirements for vehicle driving safety are constantly increasing. Most of the traffic accidents that occurred during the driving of the vehicle except for illegal driving were caused by tire failure. At present, the tires used in vehicles are generally classified into two types: pneumatic tires and solid tires. Solid tires are mainly used in a few special vehicles such as military vehicles and forklifts because of their large amount of glue, high cost, and poor cushioning. Pneumatic tires are widely used in most passenger cars, trucks and construction vehicles. Pneumatic tires were designed for the oblique tire structure in the early stage, and the carcass cords were arranged at a certain oblique angle, so it was called a bias tire. Since the invention of the radial tires by the French Michelin Company in 1947, it has gradually replaced the traditional bias tires. Because the carcass cord is at an angle of 90 degrees to the circumferential direction of the belt, it forms an arrangement like the meridian of the earth. It has many advantages such as high speed performance, good comfort, and fuel saving, thus becoming the mainstream tire in the world today. .

At present, pneumatic tires, whether it is a bias tire or a radial tire, often cause a puncture or a slow leaking abortion when a local fatigue failure occurs or is pierced by a sharp object during use, and the parking is repaired. Delaying driving time, but also endangering vehicle and life safety. Therefore, anti-claw tires and run-flat tires have become research hotspots in recent years, and some products have already entered the market. Among them, the anti-snaking technology is mainly achieved by coating the inner surface of the tire with a self-repairing material with certain fluidity and sealing, and the gas-deficient tire is mainly designed by adopting a thickened and enhanced structural design of the carcass. Realization, although it has certain practical effects, it cannot be fundamentally eliminated. In addition to safety hazards, people meet the urgent requirements for safe driving.
