| 中文摘要: |
| 针对硫化过程中胎坯胶料的流动是造成普通胎面轿车子午线轮胎带束层帘线弯曲的根本原因，设计出一种特殊形状的胎面。实验表明，应用这种预成型胎面，由于在硫化过程中胎坯的胎面形状已很接近成品轮胎的胎面形状，使胶料的流动大大减小，从而克服了带束层帘线的弯曲现象，提高了均匀性及动平衡检测的通过率。这种效果目前尚待通过批量生产轮胎进一步验证。 |
| 英文摘要: |
| The belt cord bending of passenger radial tire with conventional tread is mainly caused by the compound flow of green tire during vulcanization. A special preformed t read is designed to overcome this problem. The test shows that because the shape of preformed t read is very close to the t read shape of finished tire ，the compound flow is significantly reduced during vulcanization. Thus ，the bending of belt cord is eleminated ，the uniformity and dynamic balance of finished tire are improved.But the result s still need to be confirmed in the commercial production. |
