Problems solved by technology

[0002] At present, there are mainly two kinds of OTR tires produced at home and abroad: bias tires and all-steel radial tires. As the working environment and road conditions of OTR tires are becoming more and more harsh, and the load requirements are getting higher and higher, it is difficult for bias tires to adapt to more complex market environment
Radial tires are currently widely recognized by the market for their advantages of wear resistance, explosion resistance, fuel saving, and comfort. However, due to the high price and low cost performance of all-steel OTR tires, the market utilization rate is low

Abstract

The invention discloses a multi-mining-type high-saturability steel wire-chinlon composite body OTR radial tire. The multi-mining-type high-saturability steel wire-chinlon composite body OTR radial tire comprises a crown, a tire shoulder, a belted layer, tire body cord fabric, sidewall rubber and a tire bead. Shoulder pad compound is arranged at the joint part of the belted layer and the tire shoulder. Rubber cores and steel wire rings are arranged on the tire bead part. The belted layer comprises a steel wire cord fabric layer I, an insulating rubber plate and a steel wire cord fabric layer II. The insulating rubber plate is located between the steel wire cord fabric layer I and the steel wire cord fabric layer II. The rubber cores are formed by splicing upper triangular rubber core bodies and lower triangular rubber core bodies. The abrasion resistance of the OTR radial tire is about 20% higher than that of bias OTR tires, the oil saving performance of the OTR radial tire is about 13% higher than that of the bias OTR tires, the comprehensive service life of the OTR radial tire is about 50% longer than that of the bias OTR tires, and the OTR radial tire has high cost performance.

Description

technical field [0001] The invention relates to a multi-station type, high-saturation steel wire-nylon composite body engineering radial tire. By changing the structure and materials of the tire, its performance is a kind between the bias engineering tire and the all-steel engineering radial tire. A tire with high cost performance belongs to the technical field of tire processing. Background technique [0002] At present, there are mainly two kinds of OTR tires produced at home and abroad: bias tires and all-steel radial tires. As the working environment and road conditions of OTR tires are becoming more and more harsh, and the load requirements are getting higher and higher, it is difficult for bias tires to adapt to more complex market environment. Radial tires are currently widely recognized by the market for their advantages of wear resistance, explosion resistance, fuel saving, and comfort. However, due to the high price and low cost performance of all-steel OTR tires,...
