28L-26 14PR低断面深花纹农业轮胎的设计

Design of 28L-26 14PR low profile agricultural tire with deep tread pattern

介绍28L-26 14PR低断面深花纹农业轮胎的设计。结构设计:外直径1595mm,断面宽724mm,行驶面宽度680mm,胎圈着合直径663mm,花纹深度89mm,花纹饱和度16.5%,采用R-2型人字花纹设计。施工设计:胎面采用两方五块结构;胎体采用4层1400dtex/2V1和2层1400dtex/2V2锦纶6浸胶帘布,缓冲层采用2层930dtex/2V3锦纶6浸胶帘布;采用半芯轮式成型机成型,胶囊硫化罐硫化。成品轮胎试验结果表明,轮胎充气外缘尺寸、物理性能和帘线性能均符合相应标准要求。

A design of 28L-26 14PR low profile agricultural tire with deep tread pattern was described. In structure design,the following parameters were taken：overall diameter 1 595 mm,cross sectional width 724 mm,width of running surface 680 mm,bead diameter at rim seat 663 mm, pattern depth 89 mm,block/groove ratio 16.5%,with the design of R-2 chevron pattern block. In construction design,the following processes were taken：two-formula and five-piece extruded tread, 4 layers of 1400dtex/2V1 and 2 layers of 1400dtex/2V2 nylon 6 cord for carcass ply,2 layers of 930dtex/ 2V3 nylon 6 cord for breaker ply;using semi-flat building machine to build tire,and using capsule vulcanizer to cure tires. The inflated overall dimension, physical properties and cord property of finished tire met the requirements in the relative standards.
