Description
本发明涉及胎圈加工技术领域,具体是一种上下模不同胎圈直径的轮胎及其制造方法。 The invention relates to the technical field of bead processing, in particular to a tire with different bead diameters of upper and lower molds and a manufacturing method thereof.
胎圈又称子口,指轮胎安装在轮辋上的部分,由胎圈芯和胎圈包布等组成。它能承受因内压而产生的伸张力,同时还能克服轮胎在拐弯行驶中所受的横向力作用,使外胎不致脱出轮辋。因此它必须有很高的强力,结构应紧密坚固,不易发生变形。The bead is also called the spigot, which refers to the part of the tire installed on the rim, which is composed of a bead core and chafer. It can withstand the tension caused by the internal pressure, and at the same time overcome the lateral force of the tire during cornering, so that the tire will not fall out of the rim. Therefore, it must have high strength, the structure should be tight and firm, and not easy to deform.
该胎圈具有一母线,其轴向内端位于直径大于其轴向外端所在圆环的圆环上,这种结构类型特别适合于新型轮胎,这种轮胎在一定限度内可用于低压,甚至零压和事实上零压状态下使用,消除了该轮胎从其所安装的轮辋上分离的危险。The bead has a generatrix whose axial inner end is located on a ring with a larger diameter than the axial outer end of the bead. This type of structure is particularly suitable for new tires, which can be used for low pressure within a certain limit, even The use of zero pressure and virtually zero pressure eliminates the risk of the tire being separated from the rim on which it is installed.
中国专利(授权公告号:CN1176816C)公布了一种具有增大灵活性的轮胎的胎圈,优化了该胎体型结构形成朝向该轮胎旋转轴线超过该帘线叠层基部的伸长部分。在这种情况下,由于该胎体型结构的翻转对于固定目的来说不是不可缺少的,该翻转可没有沿该结构的环形帘线的重叠,从而使得整个胎体的类型得到了加强。但是通常地轮胎两侧的胎圈大小是一致的。这种轮胎可以安装在常规轮辋上。但对于一些特殊市场需求的轮辋,如两侧轮辋直径大小不一等。普通的轮胎因为胎圈部位尺寸的限制,造成无法正常安装轮胎。因此可以在该专利的基础上,对子午胎进行一定的优化设计。The Chinese Patent (Authorized Announcement Number: CN1176816C) discloses a tire bead with increased flexibility, and the carcass-type structure is optimized to form an elongated portion that exceeds the base of the cord laminate toward the axis of rotation of the tire. In this case, since the overturning of the carcass type structure is not indispensable for fixing purposes, the overturning may not overlap the annular cords along the structure, so that the type of the whole carcass is strengthened. But usually the size of the bead on both sides of the tire is the same. This tire can be mounted on a conventional rim. But for some rims with special market demand, the diameters of the rims on both sides are different. Ordinary tires cannot be installed normally due to the limitation of the size of the bead. Therefore, on the basis of this patent, a certain optimization design can be carried out on the radial tire.
