There is an inner tube tire as its name implies, that is, there is an inner tube filled with compressed air inside the tire. His shortcomings are high driving temperature, incompatibility with high-speed driving, poor safety, and the inner tube is in a stretched state in the tire when in use, and the small hole is formed by the puncture, and the tire rapidly depressurizes. Tubeless tires do not use inner tubes and the air fills directly into the inner cavity of the tire. This eliminates the friction between the inner and outer tires and allows the heat to be dissipated directly from the rim, cooling more than 20% more than the average tire. Tubeless tires improve driving safety. When the perforation is small, it is possible to continue driving. It is easier to repair halfway than tube tires. There is no need to disassemble the rim because it has better flexibility, so it can improve the cushioning performance of tires and improve the use of tires. life. Internal structure diagram of inner tube tire and tubeless tire Cars can have inner tubes, but the advantages of vacuum tires (tubeless tires) are too obvious, and the traditional tire structure of inner and outer tires is used less on cars. Some trucks and agricultural vehicles, due to the need to pull heavy cargo, require internal and external tires to jointly bear pressure, and some still have inner tubes. 1. No inner tube is safer than inner tube: The surface of the vacuum tire is a layer of rubber. After the inflation, the external surface tension increases, forming a certain pressure on the inner surface and improving the self-sealing ability of the break. Once broken, it is not like a bicycle. Instantly go down. When it comes to nails and the like, it is not a big problem for vacuum tires to keep running for one or two hundred kilometers. 2, no tube than the inner tube more wear-resistant vacuum tire wheel diameter than the average rim, in the driving will not be affected by the heat of the brake drum. Because there is no inner tube and lining belt, the tire and the wheel ring seal are integrated. When the vehicle is running at high speed, the high temperature generated by the friction between the tire and the road surface, the internal heat (hot air) is directly cooled by the steel ring to rapidly reduce the temperature of the tire, thereby prolonging the tire. Service life. Vacuum tire schematic 3, no tube than the inner tube more fuel-efficient, ride more comfortable vacuum tires, especially radial tires, zero crown angle, strong adhesion. It can maintain better driving stability and less friction, which is beneficial to shock absorption and speed increase. The belt speed layer has high positioning ability, the radial runout of the wheel is small, and the resistance is small. So more fuel-efficient. Comparison of all-steel and semi-steel radial tires There is no inner tube in the vacuum tire, and the variation is small when the vehicle is moving at high speed, and it can maintain better driving stability and less friction. It is obviously beneficial to the absorption of shock shock and the increase of the vehicle speed. However, tubeless tires are much thicker than ordinary inner tires. After inflated, the external surface tension increases, forming a certain pressure on the inner surface and improving the self-sealing ability of the break. Once broken, unlike the ordinary tires, the gas is instantaneous. It will continue for a certain period of time after it is drained. This will ensure the completeness of high-speed driving. The vacuum tyre brings comfort to the passengers on the vehicle and gives the driver the necessary stability in driving. So why does the car only have tires?
