介绍28×9-15 14PR宽断面工业车辆轮胎的设计。结构设计:轮胎外直径696mm,轮胎断面宽214mm,行驶面宽度208mm,行驶面弧度高6.5mm,胎圈着合直径387.5mm,胎圈着合宽度178mm,断面水平轴位置(H1/H2)0.875,采用横向块状花纹设计,花纹深度18mm,花纹周节数24,花纹饱和度71%。施工设计:胎面采用两方三块结构,胎体采用8层1870dtex/2锦纶6浸胶帘布,缓冲层采用2层1400dtex/2V2锦纶6浸胶帘布;采用半芯轮式成型机成型,立柱式硫化机硫化。成品轮胎性能试验结果表明,轮胎充气外缘尺寸和物理性能符合相应设计和国家标准要求。
Introduce the design of 28 × 9-15 14PR wide section industrial vehicle tire. Structure design: The outer diameter of the tire is 696mm, the width of the tire is 214mm, the width of the driving surface is 208mm, the curvature of the driving surface is 6.5mm, the bead diameter is 387.5mm, the bead width is 178mm, the cross-sectional horizontal axis position is 0.875 , The use of horizontal block pattern design, pattern depth 18mm, the number of pattern weeks 24, 71% pattern saturation. Construction design: The tread adopts two sides and three structures, the carcass adopts 8 layers of 1870dtex / 2 nylon 6 dipped cord, the buffer layer adopts 2 layers of 1400dtex / 2V2 nylon 6 dipped curtains; the semi-core wheel molding machine is used for molding, Vulcanizing machine curing. Finished tire performance test results show that the tire inflatable rim size and physical performance in line with the corresponding design and national standards.
