Why can't a pneumatic tire replace an inflated tire?
The advantage of this kind of tire is its light weight and no maintenance, but it has its fatal weakness:First of all, because it needs to rely on deformation to absorb vibration and pressure, it is necessary to leave a hollowed out deformation zone, which will produce very terrible wind noise when running high speed.Secondly, because the road surface is not absolutely flat, plus the weight of the vehicle, the tire rotation process is always in the deformation - recovery - re deformation of such a cycle. When running high speed, it will cause heating and fatigue due to repeated deformation of the deformed material, resulting in fatigue damage of materials and thermal attenuation damage caused by elevated temperature.In addition, due to the deformation of the tire deformation characteristics, when the emergency braking may cause damage to the wheel rim, the ground area and other issues, which makes the deformed tires are not suitable for high-speed vehicles.
This kind of tyre is characterized by its maintenance free, high wear resistance, better resistance to acid and alkaline corrosion and high temperature, better than pneumatic tyres. Used in wheeled fork loaders and wheel loaders. The disadvantage is no pressure damping function used in forklift and loader that no earthquake measures on vehicles, beating is very large, no comfort at all, a serious beating also makes the vehicle more difficult.In addition, the weight of the tire is much larger than that of the ordinary inflated tyre, and the pressure of the steel ring is higher, and the replacement difficulty is much higher than that of the pneumatic tire. And once damaged, resulting in the tire can not be repaired after the loss of circle, can only be replaced as a whole, which also caused the high cost of use.
The main reason lies in the production cost and service life, as well as driving experience.There are currently two major categories of free pneumatic tires. The first is a solid tire, as shown below:
