The vacuum wheel of the car has no inner tube, why can it have such a strong bearing capacity?

Vacuum tires are tubeless pneumatic tires, also known as:"Low-pressure tires""Pneumatic tires"Vacuum tires have high elasticity and wear resistance, and have good adhesion and heat dissipation performance, especially all-steel radial vacuum wheels, <>

Economical and durable. In recent years, vacuum tires have been widely used in bicycles, motorcycles, cars, buses, and trucks. Vacuum tires are much thicker than general inner tube tires, the surface tension increases after inflation, forming a certain pressure on the inner surface, improving the self-sealing ability of the break, once punctured, unlike ordinary tires, the gas is all discharged in an instant, and it will last for a certain time, which will ensure the safety of high-speed driving, and the comfort and stability are much better than using ordinary tires.

Vacuum tire rims have a larger diameter than regular rims and are not affected by the heat of the brake drum while driving. Due to the absence of inner tubes and liners, <>

The tire and the wheel rim are sealed as a whole, and when the vehicle is driving at high speed, the high temperature generated by the friction between the tire and the road surface is directly dissipated inside (hot air) through the steel rim to quickly reduce the tire temperature, thereby prolonging the service life of the tire. Vacuum tires are flat tires in the metric unit of 315, 295, 275, and the crown angle of the tire is zero, so the adhesion is strong, and it can maintain good driving stability and less friction, which is conducive to shock absorption and increase speed. The belt layer has higher positioning, less radial runout of the wheels, and less resistance, so it can save about 3% of fuel for the vehicle.

Now part of the truck、

Agricultural vehicles, due to the heavy loading, need the inner and outer tubes to bear the pressure together, but also use the old tires with inner tubes, because the bearing capacity of the tubeless design is not as strong as the tire with the inner tube, and the design requirements of the vacuum tire rim are extremely high, and the truck load is large and easy to open the rim.

Because the tubeless has a lot of elasticity, and the quality is also very good, it is very wear-resistant and has a strong bearing capacity.

Because there is"Pneumatic tires"Vacuum tires have high elasticity and wear resistance, and have good adhesion and heat dissipation properties.

Vacuum tires are much thicker than general inner tube tires, and the surface tension increases after inflation, forming a certain pressure on the inner surface, which improves the self-sealing ability of the breach.

Vacuum tires have high elasticity and wear resistance, and have good adhesion and heat dissipation performance, especially all-steel radial vacuum wheels, <>

Because the exterior is stronger and more wear-resistant than some other tires.

His technical principle is more advanced, the vacuum wheelset pressure withstand better, and the heat dissipation is also very good, which is worth promoting.

This is likely to be because this vacuum tire is generally characteristic, so the bearing capacity is relatively strong.

Because of the combination of special tire materials, coupled with a vacuum environment, there is a compression resistance.

Because vacuum is a technology that is built to withstand pressure.

There are other substances inside the tires of the car, and if there is an inner tube, it is easy to break.

It may be because the elasticity of vacuum tires is relatively strong and the wear resistance is relatively high, so he has a strong ability to withstand it.

Vacuum car tires are several times more resistant than those with air, and have better elasticity and wear resistance.

It must be that its tires have a special substance added to them, so they are relatively hard.

Because its outer tires are very durable, it uses some special principles.

It's because the outer tire is realized with a certain material technology, and the outer tire is enhanced.

This is one of its designs, the quality is relatively good, and the craftsmanship is superb.

A: Because of tubeless.

Abrasion resistant but not pressure-resistant, so not suitable for heavy loads.

Although there are many advantages of vacuum tubes, the disadvantages are also obvious, not pressure resistance is one of them, too much overload is not suitable for vacuum tubes.

Advantages of tubeless:

1. Slow air leakage is good to talk about, and high safety.

2. Good heat dissipation and long service life.

3. The dead weight is reduced and the fuel consumption is reduced.

4. Wear-resistant, suitable for long-distance high-speed driving.

Disadvantages of Tubeless's Friend:

1. It is not pressure-resistant and not suitable for overload.

2. Poor stability when the road conditions are bad.

3. It is more troublesome and expensive to repair well.

Because tubeless has the following advantages:

Anti-puncture = safety - the surface of the vacuum tire is a layer of high-quality rubber, the surface tension increases after inflation, forming a certain pressure on the inner surface, improving the self-sealing ability of the break, once punctured, unlike the ordinary tires of the Qiaocha shirt, the gas is all discharged in an instant, and it will last for a certain period of time, ensuring the safety of high-speed driving.

Super Wear Resistant = Saves Money – Vacuum tire rims have a larger diameter than regular rims and won't be affected by the heat of the brake drum while driving. Since there is no inner tube and lining, the tire and the wheel rim are sealed as a whole, and when the vehicle is driving at high speed, the high temperature generated by the friction between the tire and the road surface can quickly reduce the tire temperature through the direct heat dissipation of the steel rim inside (hot air), thereby prolonging the service life of the tire.

Low fuel consumption = making money - vacuum tires are flat tires in the metric unit of 315, 295, 275, and the crown angle of the tire is zero, so the adhesion is strong. It can maintain good driving stability and less friction, which is conducive to shock absorption and increase vehicle speed. The positioning of the belt layer is high, the radial runout of the wheel is small, and the resistance is small.

This results in fuel savings of up to 3%.Trucks and vans with tubeless tires have higher wear resistance, safety, comfort, and stability than ordinary tires.

Vacuum tires are tubeless pneumatic tires, also known as "low-pressure tires" and "pneumatic tires", vacuum tires have high elasticity and wear resistance, and have good adhesion and heat dissipation performance, especially all-steel Qingna meridian vacuum wheel, economical and durable.

What is a vacuum tire? Vacuum tires are tubeless pneumatic tires, also known as "low-pressure tires" and "pneumatic tires", vacuum tires have high elasticity and wear resistance, and have good adhesion and heat dissipation performance. Vacuum tires are increasingly used in bicycles, motorcycles, cars, buses, and trucks.

It is promoted by the National Economic Commission and the National Tire Association to the logistics and transportation industry. <>

Advantages of vacuum tires. Vacuum tires have the advantage of wear-resistant, vacuum tires are more wear-resistant than ordinary inflated tires, the balance performance will be better, and the driving comfort will be greatly improved, so he is also very suitable for long-distance high-speed driving. The vacuum tire can also slow down the air leakage, the vacuum tire, after being punctured, the air leakage is very slow, and it will not deflate instantly, so that we cannot drive our vehicle.

When we find that the tire is punctured, we still have enough time to drive the car to the repair station for repair. One of my favorite advantages is that he is able to reduce fuel consumption, and the weight of the tires is also reduced a lot due to the reduction of tubeless, inner tubes and rubbing electricity, which in this case naturally achieves fuel efficiency. Don't underestimate the weight of a tire, a heavier one may be dozens of pounds or even hundreds of pounds, if 4 tires are replaced at the same time, how many pounds will be saved?

Vacuum tire disadvantages. Of course, the vacuum tire also has its own shortcomings, which will be more troublesome and more expensive when repaired. Once the tubeless is punctured, it will lead to the cost of a repair of the tubeless, which is much higher than the cost of bringing an inner tube.

And if the vacuum tire is driven in poor road conditions, his stability will be poor, which will directly affect our driving feeling and make us very uncomfortable to drive, especially for passengers sitting in the car. The tubeless will not withstand pressure under load and is not suitable for overload. Although most small cars are not overloaded nowadays, the moment the car is really full, you will know how difficult it is to vacuum tires.

Vacuum tires are tubeless pneumatic tires, also known as pneumatic tires. The advantage is that once it is punctured, it will not leak immediately, and it will last for a certain time to ensure the safety of high-speed driving. The downside is that repairs are cumbersome and expensive.

It is a tire that has no inner tube, only an outer tire. The advantage of this kind of table is that the structure is simple, and the disadvantage is that the strength is relatively poor.

Nowadays, many cars will be equipped with vacuum tires, which will have a longer service life, more durable, and less prone to punctures. Cost-effective.

As the only point of contact between the car and the ground, the tire not only needs to bear the weight of the whole vehicle, but also wears a lot in daily use and is easy to be punctured, so once the tire is damaged, it needs to be repaired. However, when it comes to repairing tires, some novice drivers find a puzzling question, that is, why are the tires of medium and large vehicles equipped with inner tubes, while the family cars use real empty tires?

In fact, car tires used to have inner tubes. However, with the popularization of automobiles and the continuous innovation of technology, due to the obvious advantages of tubeless tires, the tires used in family cars are basically tubeless tires. Tubeless tires are also called vacuum tires.

Real empty tires have been used for decades, and the technology is relatively mature. For passenger cars, tubeless tires are safer than tubeless tires. Because of the characteristics of vacuum tires, even if your tires are accidentally punctured by nails, vacuum tires will not deflate as soon as they are trapped and buried in the tires.

As long as the nails remain on the tires, it is no problem to remove them after driving another hundred kilometers. This distance is enough to find a car repair shop.

In addition, real empty tires are more wear-resistant and easier to dissipate heat than tires with inner tubes. Because the rim of a vacuum tire is larger than that of a regular wheel, it is not affected by the heat of the brake drum during driving. Since there is no inner tube and inner lining belt, the tire and rim are sealed as one.

When the car is driving at high speeds, the high temperature caused by the friction between the tires and the road surface can be quickly reduced by direct heat dissipation (heat gas) through the steel rim, which is also helpful for improving safety.

In addition, due to the light weight of the empty tires, the steering flexibility of the vehicle is also better, especially the radial tires, which can maintain better driving stability and less friction, and have good grip, and the corresponding shock absorption effect and comfort are also improved. At the same time, the wheels run less, the drag is less, and it is more fuel-efficient. As a result, REAL empty tires have become the best choice for family cars.

But compared to medium and large vehicles, tires with inner tubes are still used, because large vehicles require sufficient carrying capacity, which is incomparable to tubeless tires. If medium and large vehicles use real empty tires, it is easy to inflate the rim, that is to say, if the bearing capacity is large, then the deformation of real empty tires will be large, and the heat generation will be large, which can easily lead to tire wall rubber fatigue, resulting in reduced strength, and in severe cases, punctures may occur. That's why vacuum tires aren't used for medium and large vehicles.

Millions of car purchase subsidies.
