山东群英会怎么玩 www.gs3al.cn 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。
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.
