Non-pneumatic tire capable of prolonging fatigue life

Abstract

The invention relates to a non-pneumatic tire capable of prolonging the fatigue life. The non-pneumatic tire sequentially comprises a tire crown, a supporting body and a fixed inner ring from outside to inside in the radial direction, the supporting body is composed of multiple layers of S-shaped supporting units arranged in a circumferential array. Connecting convex points are respectively distributed at four positions of the upper and lower bent parts and the left and right end parts of the S-shaped supporting unit; every two S-shaped supporting units are connected in a mirror symmetry mode through the connecting protruding points. According to the non-pneumatic tire capable of prolonging the fatigue life, the supporting body structure replaces a traditional pneumatic tire supporting face structure, the supporting effect is remarkable, meanwhile, the effect of relieving fatigue is achieved, the bearing capacity of the tire is improved, the service life of the tire is prolonged, and cost is reduced; possible factors of automobile safety accidents are reduced; when the outer tire of the tire is damaged, the movement of the inner tire cannot be affected, the supporting capacity meets the requirement through the surface structure constructed in a layer-by-layer stacking mode, manufacturing is simpler and more convenient, and the safety performance is more stable.

Description

technical field [0001] The invention relates to the technical field of tires, in particular to a non-pneumatic tire with enhanced fatigue life. Background technique [0002] With the rapid development of science and technology in the 21st century, the needs of the times and society are constantly changing. Traditional tires cannot meet these requirements due to their own structural characteristics. Various new tires have emerged. Among them, non-pneumatic tires have completely broken the traditional tire design concept and have revolutionary significance. . Non-pneumatic tires are constantly changing and improving in terms of structural design, material selection, and processing, and are developing in the direction of safety, energy saving, environmental protection, and intelligence. However, the car tire blowout problem has always existed, and it also has a great impact on the safety of the car. Traditionally, tires are severely worn due to work fatigue. What's more, if t...

Problems solved by technology

However, the problem of car tire blowout has always existed, and it also has a great impact on the safety of the car. In the traditional sense, tires are severely worn due to work fatigue.

Most of the non-pneumatic tires on the market have a small load-carrying capacity of the non-ground part, resulting in a large difference in the load-carrying capacity between the non-pneumatic tire ground part and the non-ground part, which is prone to deformation and affects the driving of the car

The patent "201110401962.4" proposes an ultra-light weight non-pneumatic tire structure based on a negative Poisson's ratio structure. Although the weight of the tire has been greatly improved, there are still some deficiencies that need to be modified, such as The negative Poisson's ratio structure is prone to stress concentration at the junction of the basic units, resulting in poor durability of non-pneumatic tires

[0004] Most of the existing non-pneumatic tires on the market do not have enough stress concentration at the joints, resulting in short fatigue life and a great waste of materials. Moreover, most of the current non-pneumatic tires are complex in structure and require a large amount of material. Therefore, a Simple structure, cost saving, less heat generation, fast heat dissipation, can reduce stress concentration and improve the life of non-pneumatic tires
