中文摘要:
      分析当前国内全钢载重子午线轮胎的市场特点及常见轮胎失效模式,介绍载重子午线轮胎用新型钢丝帘线的应用优势。在目前国内载重汽车超载、长途行驶较多的情况下,全钢载重子午线轮胎常出现抽丝爆、胎体钢丝帘线胎圈部位断爆和胎侧拉链爆等损坏现象;全钢载重子午线轮胎胎体用3+9+15×0.225 ZZZ HT,0.22+6+12×0.20HT,3×0.24+9×0.225CCHT,0.25+6×0.22+12×0.20HT等钢丝帘线,带束层用4+6×0.38/0.30HT Betru,3+8×0.33ST Betru,4+3×0.35HT,0.365+6×0.35HT Betru等钢丝帘线以及带束保护层用5×0.35/0.38HI高性能钢丝帘线可有效减少以上破坏。
英文摘要:
      The market segments in China and the major failure modes of TBR tire were analyzed,and the benefits of new steel cord constructions were introduced.Currently the trucks were usually overloaded for long drive,and typical TBR tire failure modes were carcass burst,bead burst and zipper failure.These failures can be avoided partially by using new type steel cords,such as 3+9+15×0.225 ZZZ HT,0.22+6+12×0.20HT,3×0.24+9×0.225CCHT and 0.25+6×0.22+12×0.20HT in carcass,4+6×0.38/0.30HT Betru,3+8×0.33ST Betru,4+3×0.35HT and 0.365+6×0.35HT Betru in belt,and 5×0.35/0.38HI in belt guard ply.
