Design of 7.00R16LT 14PR Light Truck Radial Tire

介绍7.00R16LT 14PR轻型全钢载重子午线轮胎的设计。结构设计:外直径膨胀率1.006,断面宽膨胀率1.020,行驶面宽度154 mm,行驶面弧度高6.15 mm,胎圈着合直径403.2 mm,胎圈着合宽度144 mm,断面水平轴位置1.098,胎面采用4条纵向花纹沟和横向分割花纹条并设刀槽花纹,花纹深度11.5 mm,花纹饱和度71.08%。施工设计:冠部胎面采用两方两块结构,胎体采用3+9×0.22+0.15HT钢丝帘线,带束层采用3×0.20+6×0.35HT钢丝帘线。成品轮胎的外缘尺寸、强度性能和高速性能符合设计或国家标准要求。

This paper introduces a design of 7.00R16LT 14PR light truck radial tire. In the structure design： the following parameters were taken： tire circumference expansion ratio 1.006, expansion ratio of cross sectional width 1.020, width of running surface 154 mm, arc height of running surface 6.15 mm, bead diameter at rim seat 403.2 mm, bead width at rim seat 144 mm, maximum width position of cross section 1.098, four longitudinal tread grooves with horizontal segmentation pattern and siping pattern, pattern depth 11.5 mm, and pattern saturation 71.08%. In the construction design, the following processes were taken： two-formula and two-piece tread for tire crown, 3＋9×0.22＋0.15 HT steel cord for carcass ply, and 3×0.20＋6×0.35HT steel cord for belt ply. It was confirmed by the tests of the finished tire that, the peripheral dimension, strength performance and high speed performance met the requirements of the design and national standard.
