| 中文摘要: |
| 介绍冬季轿车子午线轮胎的研发情况。花纹设计：采用有向、不对称花纹、多钢片设计；胎面中央采用连续的粗壮花纹块形式，4条周向主花纹沟采用Z型曲折设计，横向花纹沟采用V型设计，花纹块底部采用大弧度过渡。胎面采用无规则防滑钉设计。胎面上层胶采用专用白炭黑配方。成品轮胎性能试验结果表明，轮胎充气外缘尺寸、脱圈阻力、强度性能、耐久性能和高速性能均符合相应设计和国家标准要求；通过室外装车测试，证明该冬季轮胎设计达到国内外冬季轮胎先进水平。 |
| 英文摘要: |
| The development of winter passenger car radial tire was described. The directional and asvmmetric tread pattern was designed with multiple steel tablets. Consecutive large pattern blocks were selected in the center part of tread. Z shape design was adopted in the four circumferential main grooves and V shape was applied in transverse grooves. In the bottom of pattern block, large radius was designed for the transition. Irregular studded design was also applied on the tread. In addition, special silica filled compound was used in the upper layer of tread. It was confirmed by the tests of finished tires that the peripheral dimension, bead unseating resistance, strength performance, endurance performance and high speed performance met the requirements in the design and national standard. It was demonstrated by the outdoor test that the winter tire design reached both domestic and interna tional advanced levels. |
