具有子午线或斜交帘布层胎体的轮胎
摘要：
本发明涉及一种轮胎，所述轮胎包括至少一个胎体增强件；带束层增强件，所述带束层增强件包括第一和第二端部；胎面，所述带束层增强件包括如下不同元件：‑增强帘布层，所述增强帘布层具有横向半宽度L2，包括增强聚合物层，所述增强聚合物层设置在两个橡胶覆盖层之间，‑至少一个环箍帘布层，所述环箍帘布层安装在增强帘布层上，并且具有横向半宽度L1，并且包括两两平行的丝状增强元件，所述丝状增强元件相对于轮胎的周向方向至多形成至多等于7°的角度，所述轮胎包括至少一个边缘脱离联接橡胶层(7)，所述边缘脱离联接橡胶层(7)至少在径向上设置在环箍帘布层(5)和增强帘布层(6)之间并且设置在带束层增强件的至少一个横向端部处，所述边缘脱离联接橡胶层(7)具有在10至40mm之间的总长度和在0.2至1.2mm之间的厚度，其特征在于所述轮胎包括至少一个增强帘布层，并且在带束层增强件(3)的至少一个端部处，半宽度L1和L2不同，并且具有在5至10mm之间的差异(L1‑L2)。
摘要（英）：

Tire having at least one carcass reinforcement, a tread, a belt reinforcer having a first and a second end and: a reinforcing ply, having a transverse half-width L2, having a reinforcing polymer layer between two layers of coating rubber, at least one hooping ply, surmounting the reinforcing ply, having a transverse half-width L1, and filamentary reinforcing elements, parallel two by two, forming an angle at most equal to 7° with respect to the circumferential direction, the tire having at least one layer of edge uncoupling rubber, positioned at least radially between the hooping ply and the reinforcing ply and positioned at at least one transverse end of the belt reinforcer, the layer of edge uncoupling rubber having a total length between 10 and 40 mm and a thickness between 0.2 and 1.2 mm, having at least one reinforcing ply, and at at least one end of the belt reinforcer, the half-widths L1 and L2 are different, and manifest a difference (L1−L2) between 5 and 10 mm.
