介绍38×15.5R15AT405无内胎半钢子午线轮胎的结构设计及生产工艺。采用5°裁断角度胎体帘布有效解决了0°裁断角度胎体帘布导致的轮胎充气后胎体帘布接头处凹痕问题,对成型工艺进行控制后轮胎的均匀性一次谐波径向力波动值合格率从55%提高到90%;成品轮胎的外缘尺寸、强度、耐久性能和高速性能均符合设计要求。
The structure design and production process of 38 × 15.5R15AT405 tubeless semi-steel radial tire are introduced. The use of 5 ° cutting angle of the carcass cord effectively solve the 0 ° cutting angle of the tire carcass caused by the tire after the carcass cord pits at the indentation of the molding process to control the uniformity of the tire after the first harmonic radial force fluctuations The passing rate is increased from 55% to 90%. The finished tire’s rim size, strength, durability and high-speed performance meet the design requirements.
