Description

Double air tank run-flat tires

technical field

The utility model relates to the technical field of explosion-proof tires, in particular to an explosion-proof tire with double air chambers.

Background technique

About 30,000 people die in traffic accidents caused by car puncture every year in my country. A flat tire is as unpredictable and unstoppable as an earthquake. Tire puncture prevention technology is also a problem in the world. After decades of research and development, major automobile companies around the world have not yet found an effective solution. The tragedy of car puncture is still happening every day, and it is getting worse (now an average of 80 people die in traffic accidents caused by car puncture every day in our country). life safety of personnel. For a long time, people have thought that a car puncture is a technical no-go zone, and avoiding a car puncture is an impossible task. Therefore, the focus was on the safety of automobiles after a flat tire, and the "run-flat tire" came into being. In order to solve the safety problem after a car puncture, run-flat tires can use the tire wall strength to support the weight of the car to keep the car running safely at a speed of no more than 80 kilometers per hour by thickening the thickness of the tire wall after the car puncture. 80 kilometers per hour is not necessarily safe). It avoids the catastrophic consequences of the car blowing out of control, and achieves the purpose of tire explosion safety to a certain extent, but this method of relying on increasing the strength of the tire wall to support the weight of the car can only be used on light cars, and on large cars. With the continuous improvement of people's living standards, every household will have a car, and most car tires are still dominated by pneumatic tires.

However, most of the existing pneumatic tires do not have tire explosion-proof pads that are easy to install. Because the explosion-proof pads are not installed, the tires may be ruptured during operation, which will make the vehicle out of control and cause injuries to the staff. The existing explosion-proof pads and Most of the run-flat tires are cumbersome to install, and the comfort of the staff when driving is reduced, which is inconvenient for the staff to use, thus increasing the workload of the staff and reducing the use experience of the staff. Therefore, it is necessary to design a double air chamber explosion-proof tire. tires to solve this problem.

Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

Please refer to Figures 1-4, an embodiment provided by the present utility model:

The double air-silo run-flat tire includes a device body 1. The device body 1 includes a tire body 110. The top ends of both sides of the tire body 110 are provided with annular grooves 111. The inside of the annular grooves 111 are movably installed with gaskets 112. An annular movable groove 113 is opened inside, and a steel wire body 114 is fixedly installed inside the annular movable groove 113. The bottom ends of the two gaskets 112 are fixedly installed with an explosion-proof gasket body 115. The inside of the explosion-proof gasket body 115 is opened with a main air chamber 117. , the inside of the tire body 110 is provided with an auxiliary air chamber 118, the gap height of the auxiliary air chamber 118 is three millimeters, the top end of the annular groove 111 is placed and installed with a steel ring 119, and one end of the washer 112 passes through the steel wire body 114 and the steel ring 119. The rim is closely fitted, and the characteristics of the steel wire body 114 are used to make the device body 1 inflated, and the explosion-proof cushion body 115 is firmly fixed in the rim of the steel ring 119, which facilitates the installation of the explosion-proof cushion body 115 by the staff, thereby increasing the The convenience of the structure improves the work efficiency of the staff.

Further, the explosion-proof pad body 115 is specifically a cord sealing body, and the material of the explosion-proof pad body 115 is a rubber material. When the tire body 110 is ruptured, the characteristics of the explosion-proof pad body 115 are used to firmly block the rupture opening, thereby increasing the number of cracks. The stability of the structure is improved, and the working experience of the staff is improved.

Further, the bottom end of the explosion-proof gasket body 115 is provided with a micro communication hole 116. Using the characteristics of the micro communication hole 116, the air pressure inside the main air chamber 117 and the auxiliary air chamber 118 is in a balanced state, which reduces road noise and improves the performance. The comfort of the staff while driving the vehicle.

Working principle: When the worker uses the device main body 1, first install the gasket 112 into the inside of the annular groove 111, so that there is a gap between the explosion-proof gasket body 115 and the tire body 110 to form the auxiliary air chamber 118, and then the auxiliary air chamber 118 passes through. The micro communication hole 116 is communicated with the main air chamber 117 inside the tire body 110, and then the tire body 110 is inflated by personnel. The steel wire body 114 firmly fixes the rim, and the explosion-proof gasket body 115 is firmly fixed on the rim, and at the same time plays the role of sealing air, and the installation of the explosion-proof gasket body 115 can be completed.

When the tire body 110 suddenly ruptures during the driving process, the tire body 110 loses its sealing effect, and the air pressure balance condition between the main air chamber 117 and the auxiliary air chamber 118 disappears, so that the auxiliary air pressure between the explosion-proof pad body 115 and the tire body 110 is eliminated. The gas in the air chamber 118 is discharged, and at the same time, the explosion-proof pad body 115 is subjected to the action of the main air chamber 117 to generate a pressure difference, so that the explosion-proof cushion body 115 and the inner wall of the tire body 110 are closely attached, thereby firmly blocking the rupture opening of the tire body 110. This greatly reduces the severity of tire body 110 rupture.

It will be apparent to those skilled in the art that the present invention is not limited to the details of the above-described exemplary embodiments, and that the present invention may be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments are to be considered in all respects as exemplary and not restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, and it is therefore intended that the All changes within the meaning and range of the required equivalents are embraced within the present invention. Any reference signs in the claims shall not be construed as limiting the involved claim.
