Tubeless tires have an inner tube filled with compressed air inside the outer tube. Its disadvantages are high driving temperature, not suitable for high-speed driving, poor safety, and the inner tube is in a stretched state in the tire when in use. A small hole is formed when it is slightly punctured, causing the tire to quickly reduce pressure.
Tubeless tires do not use inner tubes, and air is directly filled into the inner cavity of the outer tube. This eliminates the friction between the inner and outer tubes, and allows heat to dissipate directly from the rim, which is better than ordinary tires in cooling. Tubeless tires are safer when driving, can continue to drive when the puncture is small, and repairs are easier without removing the rim. Because of its good softness, it can improve the cushioning performance of the tire and increase the service life of the tire.
Cars can have inner tubes, but the advantages of vacuum tires are more obvious. The traditional tire structure of inner and outer tubes is rarely seen on cars. Some trucks and agricultural vehicles need inner and outer tubes to bear pressure together because they have to pull heavy goods, and some still have inner tubes.
There is no inner tube in the vacuum tire, so the change is small when the vehicle is moving at high speed, and it can maintain good driving stability and small friction, which is conducive to increasing the speed and absorbing vibration and impact. However, tubeless tires are thicker than ordinary tube-type tires. After inflation, the surface tension increases, and a certain pressure is formed on the inner surface, which improves the self-sealing ability of the puncture. If it is punctured, the gas will not be completely released instantly like ordinary tires, but will last for a certain period of time, thus ensuring the safety of high-speed driving.
A donut-shaped elastic tube with a tire valve to maintain tire pressure
The inner tube is commonly known as the inner tube. It refers to a donut-shaped elastic tube with a tire valve to maintain tire pressure. The valve is used to inflate and keep the air at a certain pressure in the inner tube. The inner tube should have good air tightness, heat resistance, elasticity, aging resistance and small permanent deformation. It is generally made of butyl rubber.
The inner tube is an air-bearing container for inflation and vibration reduction. It is used as an auxiliary air pressure container in the inner cavity of truck, motorcycle, bicycle and rickshaw tires. It can be divided into natural rubber inner tube and butyl rubber inner tube according to the main material contained. In addition, there is a new product, pure butyl rubber inner tube, such as the "Bao Lu Jie" pure butyl rubber inner tube produced by Zhengzhou Aode Rubber. Butyl rubber inner tube products: refers to the use of butyl rubber, butyl recycled rubber as the main raw materials, adding EPDM rubber and fillers, additives, anti-aging agents and other auxiliary materials, according to a certain proportion of the formula, after mixing, mixing, molding, vulcanization and finalization, processed into various types of vehicle inner tube products.
