介绍18.4-38 10PR农业驱动轮轮胎的设计。结构设计:外直径1730mm,断面宽445mm,行驶面宽度424mm,弧度高42mm,胎圈着合直径970mm,胎圈着合宽度406.5mm,断面水平轴位置(H1/H2)0.784,采用一大一小排列的人字形胎面花纹,花纹深度38mm,花纹饱和度32.5%,花纹周节数30。施工设计:胎面采用冠部胶冷喂料挤出缠绕法、两块胎侧冷贴方式,胎体采用6层高强度1870dtex/2锦纶6浸胶帘布(4V1+2V2),钢丝圈采用Ф0.96mm的19#回火胎圈钢丝,采用LCB-4A成型机成型、短柱塞式硫化罐硫化。成品轮胎试验结果表明,轮胎的外缘尺寸和物理性能均符合国家标准要求。
Introducing 18.4-38 10PR Agricultural Drive Wheel Tire Design. Structure design: outer diameter 1730mm, section width 445mm, driving surface width 424mm, radian height 42mm, bead diameter 970mm, bead width 406.5mm, section horizontal axis position (H1 / H2) 0.784, Small arrangement of chevron tread pattern, pattern depth 38mm, pattern saturation 32.5%, the number of pattern weeks 30. Construction design: The tread adopts the crown plastic cold feed extrusion winding method, the two sidewalls cold paste method, the carcass with 6 layers of high strength 1870dtex / 2 nylon 6 dipped cord (4V1 +2 V2), the traveler uses Ф0 .96 mm 19 # tempering bead wire, using the LCB-4A molding machine, short plunger vulcanization. Finished tire test results show that the outer edge of the tire size and physical properties are in line with national standards.
