Non-pneumatic tire and wheel

Abstract

The invention provides a non-pneumatic tire and a wheel, wherein at least two springback grooves are formed in the inner tire surface, and the distance between the bottom walls of the springback grooves and the outer tire surface is controlled to be kept, that is, the springback grooves do not penetrate through the outer tire surface, so that the springback grooves are of blind groove structures,and the structural integrity of the outer tire surface is guaranteed. Meanwhile, a supporting part is formed between every two adjacent springback grooves, and when the tire body is subjected to impact force, the impact force is mainly transmitted to the supporting parts from the outer tire surface; and then the signals are transmitted to the hub through the supporting part. Due to the fact that the springback grooves are formed in the two sides of the supporting part, the elastic function of the tire body structure is effectively improved, before the impact force is completely transmitted tothe hub, the supporting part is pressed to arch towards the interiors of the springback grooves in the two sides to generate elastic deformation, the two sides of the supporting part bear springback internal stress generated by deformation of the structure, and part of the impact force is counteracted; therefore, impact energy acting on the tire body is effectively absorbed, it is guaranteed thatthe non-pneumatic tire has good buffering performance, and the riding or driving comfort of a vehicle is effectively improved.

Description

technical field [0001] The invention relates to the technical field of tires, in particular to non-pneumatic tires and wheels. Background technique [0002] Non-pneumatic tires refer to tires that achieve shock absorption and cushioning performance without the use of air pressure, that is, tires that only use the material and structure of the tire itself to achieve support and cushioning performance without inflation or air. Due to the advantages of air-free, puncture-proof, and run-flat tires, air-free tires are more and more popular among the public and are widely used in the vehicle industry. [0003] Currently, the commonly used tires have various structures and different functions, so it is difficult to achieve uniform and excellent functions and uses. The traditional non-pneumatic tire carcass structure mainly has problems such as poor comfort and insufficient elasticity. Combined with the application of actual vehicles, it is difficult to optimize and use the charact...

Problems solved by technology

[0003] Currently commonly used tires have a wide variety of structures and different functions, and it is difficult to achieve uniform and excellent functions and uses.

The traditional non-pneumatic tire carcass structure mainly has problems such as poor comfort and insufficient elasticity. Combined with the application of actual vehicles, it is difficult to optimize and give full play to the characteristics of the vehicle itself.

In this way, the user's use is seriously affected, and the comfort of riding or driving the vehicle is greatly reduced.
