一种越野轮胎的结构设计

Structural design of an off-road tire

本文介绍了285/70R17 121Q规格越野轮胎的设计。外轮廓方面:轮胎的设计外直径834 mm,充气断面宽292 mm,轮胎的行驶面宽240 mm,设计行驶面弧高度11.8 mm,胎圈着合直径取值430 mm,轮胎的胎圈着合宽度245 mm,轮胎的断面水平轴位置取值0.842 3;轮胎的胎面花纹设计分为M型和L型,2种花纹为交替变节距呈现,花纹深度13.3 mm,花纹饱和度66.26%。轮胎的施工设计方面:胎面挤出部件位全分层设计,可更好的区分胶种,功能性更强,胎侧挤出部件为双复合设计,冠带层的1#、2#带束层材料使用3×0.30 HT钢丝帘线,胎圈部位的钢丝圈为斜六角形结构,更好的保证了成品断面钢丝圈部位,切割后的近圆形;胎胚的成型使用的设备是萨驰一次法成型机,胎胚的硫化使用的设备是韩国东和液压硫化机,硫化工艺为氮气硫化。生产的成品轮胎的外缘尺寸、强度性能和耐久性能等均满足国家标准要求。

This article introduces the design of 285/70R17121Q off-road tires.In terms of outer contour:the design outer diameter of the tire is 834 mm,the inflated section width is 292 mm,the running surface width of the tire is 240 mm,the design running surface arc height is 11.8 mm,the bead diameter is 430 mm,and the tire bead width is 245 mm,and the horizontal axis position of the tire section is 0.8423.The tire tread pattern design is divided into M type and L type,and the two patterns are alternately variable pitch,the pattern depth is 13.3 mm,and the pattern saturation is 66.26%.Tire construction design:fully layered design of tread extrusion components,which can better distinguish rubber types,and has stronger functionality.Sidewall extrusion components are dual composite design,and the 1#and 2#belts of the cap layer uses 3×0.30HT steel cord,and the traveler at the bead part has an oblique hexagonal structure,which better guarantees that the finished cross-section traveler is nearly circular after cutting;The equipment used for the molding of the tire blank is Safe-run one-step molding machine,and the equipment used for the vulcanization of the tire blank is South Korean Donghe hydraulic vulcanizing machine.The vulcanization process is nitrogen vulcanization.The outer edge dimensions,strength performance and durability of the finished tires produced meet the requirements of national standards.
