以3+9+15×0.225HT钢丝帘线替代3+9+15×0.22+1NT钢丝帘线用于12.00R20 18PR全钢载重子午线轮胎胎体和带束层。结果表明,以3+9+15×0.225HT钢丝帘线替代3+9+15×0.22+1NT钢丝帘线用于12.00R20 18PR全钢载重子午线轮胎胎体和带束层,成品轮胎的外缘尺寸基本不变,轮胎强度性能、耐久性能和速度性能以及胎圈耐久性能均有较大提高,在不增加胎体和带束层质量和成本的情况下,胎体和带束层安全倍数大幅提高,从而提高了轮胎的使用安全性能和负荷能力。
Replace 3 + 9 + 15 × 0.22 + 1NT steel cord with 3 + 9 + 15 × 0.225HT steel cord for 12.00R20 18PR all-steel radial truck tire carcass and belt. The results showed that 3 + 9 + 15 × 0.225HT steel cords were used to replace the 3 + 9 + 15 × 0.22 + 1NT steel cord for the 12.00R20 18PR all-steel radial truck tire carcass and belt, the outer rim of the finished tire The size of the basic unchanged tire strength performance, durability and speed performance and durability of the bead have greatly improved, without increasing the quality and cost of the carcass and belt case, the carcass and belt safety factor substantially Improve, thus improving the safety of the use of tires and load capacity.
