PNEUMATIC RADIAL TIRE FOR HEAVY LOADS
Abstract:
A pneumatic radial tire for heavy loads that prevents occurrence of a side cut due to a projection while decelerating spread of a cut damage to a tire inner surface. In a widthwise cross section of the tire, angle α satisfies a relation 0
Abstract(Chinese):

一种用于重负载的充气子午线轮胎，其防止在对轮胎内表面的切割损伤的扩展减速的同时由于投影而发生侧切。 在轮胎的宽度方向横截面中，角度α满足关于径向线段形成连接虚拟线与轮胎外表面之间的相交线和最大轮胎宽度位置的线的关系0 <α＆nlE; 30°， 虚拟线穿过平行于轮胎轴线的最大胎体宽度位置。 角＆bgr 满足相对于径向线段形成接合最大轮胎宽度位置和切断点的线的关系0＆lt; nlE;＆bgr; <30°，并且增强橡胶设置在主体部分和翻转部分之间 胴体
