摘要
介绍295/60R22.5低断面全钢载重子午线轮胎的设计.结构设计:外直径922 mm,断面宽294 mm,行驶面宽度246 mm,行驶面弧度高9.5 mm,胎圈着合宽度248 mm,胎圈着合直径569.5 mm,断面水平轴位置(H1/H2)0.915 5,采用4条纵向花纹沟设计.施工设计:采用双复合挤出胎面,1#带束层采用4+3×0.33ST钢丝帘线,2#和3#带束层采用3+8×0.33HT钢丝帘线,4#带束层采用5×0.30HI钢丝帘线,胎体采用3 ×0.24+9×0.225CCST钢丝帘线,采用一次法成型机成型、热板硫化机硫化.成品性能试验结果表明,轮胎的充气外缘尺寸、强度性能、耐久性能和高速性能均符合国家标准和设计要求.
Abstract
The design on 295/60R22.5 all-steel truck and bus radial tires with low profile was introduced.In the structural design,the following parameters were taken:overall diameter 922 mm,cross-sectional width 294 mm,width of running surface 246 mm,arc height of running surface 9.5 mm,bead width at rim seat 248 mm,bead diameter at rim seat 569.5 mm,maximum width position of cross-section(H1/H2)0.9155,using 4-longitudinal pattern grooves.In the construction design,the following processes were taken:using coextruded tread compound,4+3×0.33ST steel cord for 1# belt,3+8×0.33HT steel cord for 2# and 3# belts,5X0.30HI steel cord for 4# belt,3 × 0.24+9 × 0.225CCST steel cord for carcass,using one-stage building machine to build tires and hot plate vulcanizing press to cure tires.The test results of the finished tire showed that,the inflated peripheral dimension,strength,durability and high-speed performance met national standards and design requirements.
