Lightweight Construction Design on 7.00R16LT All-steel Light Truck and Bus Radial Tire

介绍7.00R16LT全钢轻型载重子午线轮胎的轻量化施工设计。带束层由3层结构调整为2层结构,钢丝圈结构由3-6-3调整为4-6-4,内衬层厚度减小0.2 mm,隔离胶宽度减小60 mm,三复合总宽度从205mm减小至200mm。结果表明,轻量化后的成品轮胎充气外缘尺寸、强度性能、耐久性能、高速性能、胎圈耐久性能均符合设计、国家标准和企业标准要求,成本明显降低。

The lightweight construction design of 7.00R16LT all-steel light truck and bus radial tire was introduced.The belt layer was adjusted from the three-layer structure to the two-layer structure and the structure of bead wire was adjusted from 3-6-3 to 4-6-4.The thickness of the inner liner was reduced by 0.2 mm.The width of the isolation compound was reduced by 60 mm and the width of the triplex side wall was reduced from 205 mm to 200 mm.The results showed that the inflated peripheral dimension,strength,endurance performance,high-speed performance and bead endurance of the finished lightweight tire met the requirements of the design,corresponding national standards and enterprise standards,and the cost was significantly reduced.
