The invention discloses a low-section tire belt ring for heavy load and a manufacturing method and application of the low-section tire belt ring, and belongs to the technical field of off-the-road tires. According to the technical scheme, the belt ply comprises a first belt ply, a second belt ply, a third belt ply, a fourth belt ply, a fifth belt ply and a sixth belt ply; each of the first belted layer and the sixth belted layer is composed of two half-layer structures which are symmetrically arranged, and the other belted layers are of a whole-layer structure penetrating through the tire crown; and the end parts of the belted layers are arranged in a staggered manner. The tire produced by adopting the belt ring is high in tread grounding mark rectangularity rate, uniform in crown stress and low in heat generation during use; after the tire is inflated, the crown part is uniformly expanded, the outer edge after inflation is stable in size, and the service life is longer.
本发明公开了一种重载用途的低断面轮胎带束环及其制作方法和应用,属于工程机械轮胎技术领域。其技术方案为:包括第一带束层、第二带束层、第三带束层、第四带束层、第五带束层和第六带束层;第一带束层和第六带束层均由对称设置的两个半层结构构成,其余带束层均为贯穿胎冠的整层结构;各带束层的端部错开设置。采用本发明的带束环生产出的轮胎的胎面接地印痕矩形率高、冠部受力均匀、使用时生热低;轮胎充气后冠部膨胀均匀,充气后的外援尺寸稳定,使用寿命更长。
