As the only vehicle contact with the ground, the importance of tire is self-evident. Although most mass-produced vehicles still use traditional tires at this stage, the major tire manufacturers have not stopped tire innovation. These tyres for the future design are still limited by various factors at the present stage, but they bring new ideas or lay a solid foundation for tyre change. Now let's look at the tyres of the future.
For driving life, tire burst is not only a very depressing thing, but also may endanger our lives. In order to solve this problem, various modifications have been made to tyres. The first concept that we mentioned today, tire, can solve this problem, is the airless tire.
In fact, similar concepts have been used in NASA's lunar landing program as early as 2006. According to the editors, the most important idea of this kind of airless tire is not to worry about the impact of environment and terrain on tires in a short time. Previously, similar products were mostly in the conceptual stage, but before that, mass production was realized on Polaris'latest ATV. With the maturity of technology, it is believed that it is impossible to assemble airless tires on some special mass-produced vehicles.
The traditional tire cushioning function is realized by introducing new material and constructing geometric figure. However, the application of new materials is currently expensive, and the buffer force realized by structure alone is difficult to compete with the traditional pneumatic tire. In addition to the high price, elasticity and noise, the rolling resistance of the tire is much greater than that of the traditional pneumatic tire, so it can not adapt to high-speed driving. It is precisely these factors that are difficult to break through, so that although airless tires have many advantages, such as wear resistance, strong environmental adaptability and high quality, they are still difficult to popularize in civil vehicles. But with the development of science and technology, these problems really can not be solved? Let's wait and see.
Tyre Pressure Control
The importance of tire pressure for driving safety is self-evident, such as tire pressure monitoring, gas shortage maintenance and other solutions on tire pressure emerge in endlessly. Despite the airless tires we mentioned earlier, Goodyear's tire with automatic tire pressure control technology provides a new direction for the development of traditional tires.
In fact, the structure of tyre pressure automatic control technology is not complicated, compared with traditional tyres, there are only more gas storage tanks and tyre pressure monitoring valves, so we can still expect it to be mass produced as soon as possible. The principle of tire pressure automatic control technology is also simple: when the tire pressure is below the standard pressure, with the rolling of the tire, the air in the air storage pipe is squeezed at the bottom of the tire and enters the tire through the intake valve. The tire pressure monitor is responsible for controlling the opening and closing of the intake valve. When the tire pressure is below the standard value, the intake valve will be opened, and the tire pressure will return to normal before closing.
Data show that ordinary tires reduce tire pressure by 0.1 Bar per month. The tire with automatic tire pressure control technology can be automatically inflated at the first time of air shortage. Proper air pressure helps to reduce emissions, prolong service life and increase vehicle safety.
However, it should be noted that the tire pressure automatic control process is only positive, that is, only like the compressed air inside the tire, when the tire pressure is too high, it can not automatically control the air output. In addition, the tire control is only for the normal tire. When the tire is tied, the tire pressure will decrease rapidly, and the tire pressure control can not guarantee the safety of the vehicle.
The retractable tire is a concept tire developed by Finnish tire manufacturer Nokian tire. For higher latitudes, changes made to winter tires may surprise them. Aiming at the problem of tire grip weakening caused by frequent rain and snow in winter, the retractable bolts are equipped to improve the grip of tire on wet and slippery road while minimizing the impact on dry ground performance.
Compared with the traditional tire with bolt structure, the biggest feature of this tire is the flexibility of bolts. The expansion of the bolt is realized by the start button. When the road condition does not need the assistance of bolts, the contact part with the ground is still rubber, which ensures that the tire can provide good comfort and maneuverability. When encountering wet and slippery pavement, the starting bolt can greatly enhance the adhesion with the pavement. This is absolutely a good news for winter snow and ice areas. No wonder it was invented by Nordic companies.
It is not easy to achieve this function because the control device needs to change the internal structure of the tire, which not only increases the weight of the tire to a certain extent, but also may lead to dangerous changes in the internal structure. So this tire is still in the concept stage, friends in the north have to wait.
