AI Technical Summary

Technical Problem

Existing non-pneumatic tire support structures are complex and difficult to simultaneously possess good load-bearing and cushioning performance, making them prone to tire blowouts at high speeds and unsuitable for high-load vehicles.

Method used

It adopts a three-layer tread ring skeleton and buffer support structure, including tread ring base rubber layer, tread ring skeleton and rim. The support spokes are made of steel cord material and polyurethane and designed into a frustum shape to optimize deformation characteristics. Combined with high-strength rubber material and steel rim, it forms an overall support and buffer structure.

Benefits of technology

It achieves the same support capacity and cushioning performance as pneumatic tires for high-load-bearing non-pneumatic tires, avoiding tire blowout problems, and is suitable for engineering vehicles and long-haul trucks, reducing production costs.

Abstract

The utility model belongs to the technical field of tires, and particularly relates to a high-bearing-capacity non-pneumatic tire which comprises a tread layer, a buffer supporting body and a rim, the tread layer comprises a tread ring base rubber layer, the outer surface of the tread ring base rubber layer is provided with tread patterns, and a tread ring framework is arranged in the tread ring base rubber layer; the tread ring skeleton is sequentially composed of a first layer of tread ring skeleton, a second layer of tread ring skeleton and a third layer of tread ring skeleton inwards along the tread pattern side of the tire, and the three layers of tread ring skeletons are made of a steel wire cord material; the included angle between the first layer of tread ring framework and the circumferential direction of the tire is 23-25 degrees, the included angle between the second layer of tread ring framework and the circumferential direction of the tire is 14-16 degrees, and the included angle between the third layer of tread ring framework and the circumferential direction of the tire is 14-16 degrees. By optimizing the structure and the material of the non-pneumatic tire, the non-pneumatic tire has higher bearing capacity; the pneumatic tire has the same supporting capacity and buffering performance as a pneumatic tire, the problem of tire burst of the pneumatic tire is thoroughly solved, and traffic accidents are avoided.
