斜交轮胎原理

斜交轮胎(diagonal tire ；bias tire )又称普通结构轮胎，代号“B”。指胎体帘布层和缓冲层相邻层帘线交叉，且与胎面中心线呈小于90℃角排列的充气轮胎。这种轮胎纵向刚性好，适于在普通路面中速行驶。

斜交轮胎可以简单的称之为尼龙胎。这个概念是相对于子午线轮胎即所谓的钢丝胎而言的。

斜交轮胎的胎体帘布层是由数层挂胶帘布组成，相邻的帘布层帘线角度相同，相互交叉排列,帘布层数一般为偶数，这样能使胎体帘布层负荷均匀分布。斜交轮胎胎冠帘线角度通常取48度到55度之间，胎冠帘线角度是指帘线与胎冠中心垂直线的夹角。帘布层分为内帘布层和外帘布层两部分。内帘布层是胎体主要的骨架层，其特点是层数多，帘线密度较密，使胎体强度增大。外帘布层位于内帘布层与缓冲层之间起过度作用，又称之为胎体的辅助层，其特点是层数少，通常只有两层，帘线密度较内帘线稀疏，附胶量较多，捏着强度较高，缓冲层位于外帘布层与胎面胶之间，其结构由胶片或两层以上挂胶帘线组成，布层的上，下或中间加贴缓冲胶层。缓冲层帘布比外帘布层的密度稀疏，挂胶厚度较厚，帘线角度等于或稍大于帘布层帘线角度，相邻布层相互交叉排列，起宽度一般稍大或稍窄于胎冠宽度。通常载重轮胎的缓冲层采用挂胶帘布与胶片组合结构，轿车轮胎也可采用缓冲胶片作为缓冲层。

tire carcass ply is composed of several layers of rubber cord, adjacent ply cord angle, cross ply arrangement, is generally even, so that the carcass ply uniform load distribution. Bias tire tire crown cord angle is usually between 48 degrees to 55 degrees, the crown cord angle is the angle between the cord and the crown center vertical line. The ply is divided into two parts: the inner ply and the outer ply. The inner ply is the main skeleton of the carcass, which is characterized by the number of layers and the density of the cord, and the strength of the carcass is increased. Since the excessive effect between the outer plies located within the cord fabric layer and buffer layer, also known as the auxiliary layer of the matrix, which is characterized by a small number, usually only two layers, cord cord in density is sparse, more adhesive amount, holding high strength, the buffer layer is positioned between the outer ply and tread the structure of the film adhesive, or more than two layers of rubberized cord, cloth layer, or the middle layer affixed buffer. The buffer layer ply than sparse density outer plies, hanging glue thickness, cord angle is equal to or slightly larger than the ply cord angle, adjacent fabric layer mutually staggered up width is generally slightly larger or slightly narrower than the crown width. Generally, the buffer layer of the truck tire is made up of the cord fabric and the film structure.
