15-19.5 14PR无内胎工业车辆轮胎的结构设计

介绍15—19.514PR工业车辆轮胎结构设计和施工设计。在结构设计方面，增大行驶面宽度和胎侧厚度；胎冠为反弧形；花纹块为梯形过渡，避免应力集中。在施工设计方面，胎面采用两方三块，冠部使用耐磨性好的胶料，侧部采用定伸应力大、压缩变形小的胶料。另外，优化和加强了工艺管理，成品轮胎外观缺陷减少，使用性能优异。

Structure design of 15-19.5 14PR tubeless industrial tire

The structure design and construction design of 15-19.5 14PR tubeless industrial tire are described.In structure design,the width of tread running surface and the thickness of sidewall are increased;the inverse arc crown is used;and the trapezoidal transition tread blocks are used to prevent the stress concentrating.In construction design,two formula and three pieces are used in the tread,a good wear resistant compound is used in the crown and a compound with higher modulus and lower compression set is used in sidewall.In addition,the processing technology is optimized and the technology management is strengthened.Thus,a finished tire with less appearance defects and excellent performance is obtained.
