Technical Field

The invention belongs to the technical field of tires, and particularly relates to an explosion-proof tire.

Background

The explosion of the automobile tire refers to the phenomenon that the automobile tire loses pressure within a short time (less than 0.1 second) and explodes. Because the pressure of the tire can be released instantly, violent shock waves are generated, and larger cracks or defects can be generated on the tire. The total length of the breach often exceeds 30 cm. The tire explosion happens in a moment, the response time is short, the harm is great, and accidents and personal injuries are often caused. When the tyre is punctured, the tyre is usually cracked instantly, so that the tyre loses the supporting force instantly, the gravity center of the vehicle is changed instantly, particularly, when the front wheel of a front wheel drive vehicle is punctured, the vehicle is out of control by instant gravity center transfer after the tyre is punctured. If the driver does not experience driving after a tire burst (most people do not), a wrong driving action (e.g., hard braking) may be made, which may result in an irreparable loss of control of the vehicle.

Disclosure of Invention

The invention provides a run-flat tire, which aims to make up the defects of the prior art and solve the problems that after the tire burst occurs in the high-speed running process of a vehicle, the vehicle generates violent vibration, the operation and control of a driver are influenced, and finally the vehicle is out of control to cause the inclination and the overturn of a vehicle body.

The technical scheme adopted by the invention for solving the technical problems is as follows: the invention relates to an explosion-proof tire, which comprises a wheel hub; an outer tire is fixedly arranged on the surface of the outer diameter of the hub; the outer tire is fixed through a bending part at the edge of the hub; a main reed is fixedly arranged on the surface of the outer diameter of the hub; the main spring plates are multiple in number and are uniformly distributed around the central line of the hub; the main reed is arc-shaped; the main reed is positioned in a space formed by mutually enclosing the outer tire and the surface of the outer diameter of the hub, and the main reed is not contacted with the outer tire;

when the automobile tire pressure-loss device works, in the process of driving of an automobile, under the condition that the tire is intact, the main reed on the hub cannot contact the outer tire, the problem that the position, contacting the main reed, on the inner side surface of the outer tire is seriously abraded due to frequent contact and friction between the main reed and the outer tire, so that the outer tire is broken and the normal use of the tire is influenced is avoided, meanwhile, when the automobile tire bursts due to an accident in the process of driving of the automobile, the space formed by the mutual enclosure of the outer tire and the outer diameter surface of the hub is directly communicated with the outside, so that the tire is subjected to pressure loss, meanwhile, after the tire loses the bearing effect, the area, contacting the tire and the ground, collapses under the action of the gravity applied to the automobile until the outer tire contacts the main reed on the outer diameter surface of the hub, the supporting effect is generated through the main reed, and the tire is prevented from falling suddenly after being damaged, so that the hub is contacted with the ground to generate support, when the main reed is used for supporting and advancing the wheel through the main reed, certain elastic deformation occurs when the main reed generates a supporting action, and the impact force generated by the sudden falling of the center line of the wheel after the tire burst is buffered, guarantee the vehicle safety of traveling, simultaneously, through the effect that has elastic main reed, can be after the vehicle blows out, the in-process that slows down and stop reduces vibration, the shake of the appearance that the wheel marchd the in-process, reduces the vibration that the vehicle appears, the driver of being convenient for is to the control of the vehicle after blowing out.

Preferably, a chain belt is fixedly arranged in a space formed by the outer tire and the surface of the outer diameter of the hub in a mutually enclosed manner; the chain belt is annular, and one end of the main reed, which is far away from the hub, is contacted with and extrudes the inner diameter surface of the chain belt; the chain belt does not contact the outer tire;
