10.00R20加强型全钢载重子午线轮胎的设计

Design on 10.00R20 Reinforced Truck and Bus Radial Tire

介绍10. 00R20加强型全钢载重子午线轮胎的设计。结构设计:外直径1 060 mm,断面宽276 mm,行驶面宽度214 mm,行驶面弧度高7. 9 mm,胎圈着合直径511 mm,胎圈着合宽度203 mm,断面水平轴位置(H1/H2)1. 026,采用大块混合花纹设计,花纹深度22. 8mm,花纹块饱和度62%,花纹周节数39。施工设计:胎面采用分层结构,胎体采用3+9+15×0. 20ST钢丝帘线,1#和2#带束层采用3+9+15×0. 22钢丝帘线,3#带束层采用3×4×0. 22HE钢丝帘线,2层0°带束层采用3×7×0. 20HE钢丝帘线。采用一次法成型机成型,蒸锅式硫化机硫化。成品性能试验结果表明,成品轮胎的充气外缘尺寸、强度、耐久和高速性能均达到设计及用户要求,且满足国家标准要求。

The design on 10.00R20 reinforced truck and bus radial tire was described.In the structure design,the following parameters were taken:overall diameter 1060 mm,cross-sectional width 276 mm,width of running surface 214 mm,arc height of running surface 7.9 mm,bead diameter at rim seat 511 mm,bead width at rim seat 203 mm,maximum width position of cross-section(H1/H2)1.026,using large mixed pattern design,pattern depth 22.8 mm,block/total ratio 62%,and number of pattern pitches 39.In the construction design,the following processes were taken:layered construction for tread,3+9+15×0.20ST steel cord or carcass,3+9+15×0.22 steel cord for 1#and 2#belt,3×4×0.22HE steel cord for 3#belt,and 3×7×0.20HE steel cord for two 0°belts.One-stage building machine was used to build tire and steamer type press was applied to cure tire.It was confirmed by the finished tire test that,the inflated peripheral dimension,strength,endurance and high speed performance met the requirement of the design and national standard.
