Changing tires has a certain impact on braking and steering. In non-professional situations, it is not recommended to replace them yourself!
We all know that bicycles, motorcycles, agricultural machinery vehicles, some trucks, etc., tires have inner tubes, inner tubes are soft, gas is in the inner tube, and the outer tube is relatively hard, the main role is to protect the inner tube. But the car is different. The tires don't have inner tubes, and they don't leak. Why? At present, some trucks and agricultural vehicles, because of the heavy weight of the goods, need to be under pressure with the inner and outer tires, and also use the old-fashioned tires with inner tubes, because the carrying capacity of the vacuum tires is not as strong as that of the inner tubes, and the rims of the vacuum tires The design requirements are extremely high, and the cargo truck has a large weight and is easy to expand the rim. However, relatively speaking, passenger cars are made of tubeless tires. Tubeless tires are called atomic tires or vacuum tires. They are generally divided into radial tires and bias tires. There is no difference in the structure of these two types of pneumatic tires. It is composed of rubber parts and plies, and the core component of the tire that helps the car resist external forces is the ply. Many people mistakenly think that they are thick rubber parts, but it is not. Rubber plays a role in sealing, abrasion and cushioning in the use of tires. The oblique line tires are known literally because the curtain warp threads are obliquely skewed to each other, hence the name. Radial tires are also named as radial tires because the arrangement of the cords is arranged like a meridian on the globe. The vacuum tire utilizes the inner liner of the tire and the inner liner of the rim to ensure good airtightness between the tire and the rim, and the outer tire also functions as a inner tube. The edge of the tire is a smooth airtight layer, mounted on the hub. After inflation, the tire is pressed tightly against the hub by the pressure of the air. The tire is not equipped with a tube, and the tire itself has a tube structure because there is no tube. The inside of the tire has an airtight layer. The inner liner is made of synthetic rubber, which seals the compressed air inside the tire (equivalent to the function of the inner tube). The higher the pressure, the tighter the pressure and the better the air tightness. After the vacuum tire is inflated, the external tension increases, and a certain pressure is formed on the inner surface, which improves the self-sealing ability of the periphery and the break. Even if it is broken by a hard object such as a nail, it will not collapse like a bicycle, but also You can stick to a road.
As the performance and driving speed of the vehicle increase, the disc brake has become the mainstream of the current braking system in order to increase the stability of the brakes at high speeds...
