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

This utility model belongs to the field of tire technology, specifically relating to a high-load-bearing non-pneumatic tire, including a tread layer, a buffer support body, and a rim. The tread layer includes a tread ring base rubber layer, the outer surface of which is the tread pattern, and a tread ring skeleton is disposed within the tread ring base rubber layer. The tread ring skeleton is composed of a first tread ring skeleton, a second tread ring skeleton, and a third tread ring skeleton sequentially from the side of the tire tread pattern inward. The three tread ring skeletons are made of steel cord material. The angle between the first tread ring skeleton and the tire circumference is 23-25°, the angle between the second tread ring skeleton and the tire circumference is 14-16°, and the angle between the third tread ring skeleton and the tire circumference is 14-16°. By optimizing the structure and materials of the non-pneumatic tire, it possesses high load-bearing capacity; it has the same support capacity and buffering performance as a pneumatic tire, completely solving the problem of tire blowouts of pneumatic tires and avoiding traffic accidents.
