Description

Bulletproof wheel for tires

The present invention relates to a bulletproof wheel for a tire, and more particularly, to prevent puncture and breakage of a tire, which is connected to a rotating shaft of a vehicle body installed in a vehicle, plays a role in improving the ride comfort of a vehicle and is responsible for moving forward and turning brakes of a vehicle The present invention relates to a bulletproof wheel for a tire that can prevent accidents and provide safe operation.

In general, a vehicle is provided with a tire that rotates while being in contact with the ground and performs dynamics of driving and braking the vehicle. As shown in FIG. 1, the tire 1 is provided with a wheel 1 at a central portion thereof and a tire 2 mounted on an outer circumferential surface of the wheel 1. The tire 2 uses a tire 2 having a thinner side as a luxury car. Because the thinner the thickness of the side of the tire 2, the riding comfort is improved. However, the tire 2 having a thin side thickness has a high breakage rate, and the occurrence of accidents is sharply high, but at present, there is a limitation in manufacturing a thin side thickness.

That is, the tire 2 having a thin side has a tire 2 as shown in FIG. 2 when the internal air is rapidly expanded due to excessive internal pressure (shock) of the vehicle body or high temperature (summer season) due to overpressure during sudden braking or driving. The side of the projecting to the outside is broken.

In addition, tires are easily damaged by external shocks (various debris or physical tools). Such a tire 2 can be repaired if a puncture occurs on its bottom, but if the side is broken, the tire 2 can no longer be used.

In order to solve this problem, thickening the thickness of the side of the tire 2 prevents breakage, but the ride quality is significantly low, and the vehicle body trembles tremendously, increasing the fatigue of the driver and the rider, and in particular, due to the increased noise during driving, Since vibration is transmitted, nerves are dispersed, and the accident rate is increased because it is unable to concentrate on safe driving.

The present invention is invented to solve the above problems, the object is to prevent the tire from being damaged from the impact from the outside without thickening the thickness of the side of the tire to extend the service life of the tire as well as provide safe driving. The present invention provides a bulletproof wheel for a tire.

Referring to the characteristic configuration of the present invention for achieving the above object is as follows.

Bulletproof wheel for a tire of the present invention is a housing fitted to the central portion of the tire, an inner protective plate formed to extend on one side of the housing to surround the inner side of the tire, and the other side of the housing to surround the outer side of the tire It includes an outer shield installed detachably / joined via bolts.

Bulletproof wheel of the present invention is installed to surround both sides of the tire to prevent various impacts, so it must be able to withstand the strong impact (gun bullet) and the thinnest and lightest cutting-edge materials (special aluminum (Al7075): specific gravity = 2.8, titanium: specific gravity = 4.507, PC poly: specific gravity = 1.2, carbonate, etc.). (Metals with low specific gravity are lighter at the same size (volume))

The present invention can also be used for general tires, and when used for general tires, it is preferable to maintain a predetermined thickness so as not to be damaged by an external impact (auger or the like).

This is because the manufacturing cost (ballistic wheels have to be made thicker than aluminum wheels) can be reduced, thereby reducing fuel consumption. However, aluminum wheels are fragile and bullets cannot be prevented and protected from internal shocks and external sharp awls. Bulletproof wheels and aluminum wheels differ only in material and thickness, and are manufactured in the same size, so that the two can be selected and mounted.

Bulletproof wheels are used for special tires (tires with puncture protection and wear indicators) or bulletproof vehicles because the manufacturing cost increases and weight increases, and the tires have excellent protection and can prevent accidents caused by tires. In addition, the bulletproof wheel has a thickness that cannot be penetrated, and when it is thick, it is used by forging (heat treatment work that does not change the material and shape, but changes the thickness when the thick metal is subjected to high pressure shock at high temperature).

Hereinafter, with reference to the accompanying drawings showing the present invention will be described in detail.

3 is a cross-sectional view showing a bulletproof wheel according to the present invention, Figure 4 is a cross-sectional view showing a tire equipped with a bulletproof wheel according to the present invention, Figure 5 is a front view showing a tire equipped with a bulletproof wheel according to the present invention.

As referred to herein, the present invention includes a housing 10 fitted to a central portion of the tire 30, and one surface of the housing 10 includes an inner protection plate 11 to surround the inner side surface of the tire 30. Is formed.

On the other hand, the other side of the housing 10 is provided with an outer protective plate 12 to surround the outer side of the tire 30, the outer protective plate 12 is detachable / coupled via the bolt 20 as a medium. It is installed.

The outer diameter of the inner protective plate 11 and the outer protective plate 12 is preferably produced in a size of about 2/3 to 4/5 of the outer diameter of the tire 30.

Because the outer diameter of the inner protective plate 11 and the outer protective plate 12 is equal to the outer diameter of the tire 30, the ride comfort is reduced by contacting the ground, if too small is exposed to the external impact, the size is taken into consideration To make it as large as possible.

In addition, the inner protective plate 11 and the outer protective plate 12 are preferably installed to maintain a predetermined distance (G) with the tire 30. This is because the tire 30 is prevented from contacting the inner protective plate 11 and the outer protective plate 12 when the tire absorbs the vibration when the tire 30 vibrates, and the interval is maintained at about 5 to 10 mm. It is.

The vehicle equipped with the bulletproof wheel according to the present invention configured as described above is to prevent the tire from being damaged by bullets as well as various sharp objects (awls) since both sides of the tire 30 are protected from external impact.

As such, the present invention prevents the tire from being damaged, thereby providing safe driving under any circumstances to accomplish various tasks.

In particular, military emergency goods (wartime) material transport quarreled with the village, so a little delay can be a lot of sacrifices and operations will cause a lot of obstacles. At this time, if a puncture and breakage (gun bullet, debris, etc.) occurs in the tire, the time is delayed, causing a disruption to the mission and a lot of sacrifice.

Military goods transport runs on rugged mountain roads, causing frequent punctures and tire damage to bullets and debris. In this case, if the tire is damaged, it is not easy to replace the tire in an urgent situation and it takes a lot of time even if it is replaced.

Tires with puncture-proof and bulletproof wheels do not cause punctures and breakage under any circumstances, making it easy to get out of an emergency situation.

There are also occasions when gunfights occur when the police chase the criminal.

If punctures or damages occur on the tires of police cars, the criminals cannot be arrested. This must be solved because the safety of the people must be given priority.

In this case, vehicles equipped with puncture-proof and bulletproof wheels do not have punctures or breakage under any severe conditions and the tires are safely protected from shooting by criminals.

And cars are often exposed to terrorist shootings. In general, tires are easily damaged (punctured) by shooting and cannot move quickly in a dangerous place.

However, in the present invention, a vehicle equipped with a bulletproof wheel can easily pass through such a dangerous place, thereby improving safety.

In normal vehicles, illegal tire breaks (awls) frequently occur during parking.

Tires with bulletproof wheels are not easy to break. That is, in order to damage the tire, it is possible to disassemble all the bulletproof wheels. It is difficult to dismantle the bulletproof wheel in this unstable situation. Bulletproof wheels are fixed with internal bolts, so special tools are required for dismantling. Bulletproof wheels are fixed by high-pressure mechanical coupling, so they cannot be easily separated by artificial force. In addition, it takes a lot of time and can not be easily broken.

All parts of the bulletproof car (body and glass are solid, but tires are exposed as vulnerable parts).

For example, the following is reported in the Ilhwa Chinese newspaper during the war in Iraq (Jungang Ilbo, April 10, 2004).

"British journalist Stephen Farrell rented a bullet-proof Mercedes car and drove on a highway into the desert. He was desperately trying to escape from a bullet-struck road in Fallujah, 32 km ahead of Baghdad. I was held. "

As such, tires are important and exposed to external shock, which is essential for safety development. Some economic consumption cannot replace precious lives. For this reason, tires with puncture resistant and bulletproof wheels are most efficient for bulletproof vehicles.

In addition, bulletproof wheels do not have international standards, and if adopted to international standards, they will lead international competitiveness and generate many economic benefits (technical fees), and this invention can lead international standardization (technical standards).

The improved aluminum wheels and bulletproof wheels are not consumable, so they can be used together with the life of a car with a single purchase.

When the improved aluminium wheels or bulletproof wheels are installed, the thickness of the tire side is made a little thinner than that of the existing tires, resulting in an excellent ride comfort.

That is, since the wheel is prevented from damage to the tire, an accident due to the damage of the tire does not occur.

The tires are also black with carbon, making the car feel dark. When painting a color directly on a tire, it is unsightly peeled off by the continuous action of rubber shrinkage and swelling.In this case, various paints can be produced by applying various paints to the wheel to express various phrases (trademarks, etc.) Painting a picture does not damage for a long time and the car feels bright.
