Technical Field

The invention relates to the field of automobile tires, in particular to an explosion-proof zero-pressure protection tire.

Background

Tires are important components of automobiles and are the only parts of automobiles that contact the road surface. If the tire burst happens in the high-speed running process, the vehicle is easily out of control, and the vehicle is easy to get out of control and is in danger of rollover. If the air leakage happens, the automobile cannot run, tires need to be replaced, the time is delayed, and the loss is caused if the automobile runs in rainy and snowy days or in cold winter, or participates in important meetings, or is driven by airplanes. If it is a physical activity and a visceral activity for a female, it is a worried about changing the fetus. How to enable a vehicle not to generate the out-of-control condition when the tire is punctured and still continue to run without replacing the tire when the tire is punctured needs to be developed, so that the tire still can run after the tire is punctured or in the state of zero air pressure.

Disclosure of Invention

Aiming at the defects in the prior art, in order to overcome the defects in the prior art, the vehicle tire which can work in a zero-pressure state and keep a good working state is provided, and the following specific technical characteristics are provided:

the anti-explosion zero-pressure tire comprises an inner liner layer, a tire shoulder part, a tire side part and a tire lip part, wherein the tire crown part is arranged on the tire, and the tire shoulder part, the tire side part and the tire lip part are sequentially connected; a steel wire belt layer is arranged in the tire crown part, a high-strength steel wire reinforcing layer is arranged at the intersection position of the tire side part and the tire lip part, and a tire bead steel wire and a low-heating rubber core are arranged in the tire lip part; and carcass plies are arranged in the tire shoulder part, the tire side part and the tire lip part.

As the preferred technical scheme, the high-strength steel wire reinforcing layer is arranged between the low-heating rubber core and the carcass ply.

As the preferred technical scheme, the high-strength steel wire reinforcing layer is arranged on the outer side of the carcass ply and is far away from the low-heating rubber core.

Preferably, the carcass ply is turned up around the bead wire bottom and then the outer end thereof extends radially upward.

As a preferred technical scheme, a reinforcing support rubber is arranged between the carcass ply and the inner liner, and two ends of the reinforcing support rubber respectively extend to the shoulder area and the bead area.

As a preferred technical scheme, the shape of the reinforcing support glue is crescent.

Preferably, the tire further comprises an inner liner, and the inner liner is arranged on the innermost side of the tire.

According to a preferable technical scheme, a steel belt layer is arranged on the outer surface of the air-tight layer.

Due to the adoption of the technical scheme, the explosion-proof zero-pressure tire has the advantages that the bending degree of the tire body cord fabric in the internal pressure loss process of the tire is reduced and the integral rigidity strength is improved by arranging the high-strength steel wire reinforcing layer. Therefore, the automobile can run at a speed of 80km/h for more than 80km under the condition that the air pressure in the automobile tire is zero. The safety of a driver under an emergency situation is ensured, and the inconvenience of replacing the tire for the driver or a user is reduced.
