摘要： Tyres for vehicle wheels having reduced environmental impact and the components thereof, in particular reinforcing structural elements such as carcass structures, belt structures, flippers and chafers, include elongated reinforcing elements treated with resorcinol and formaldehyde-free cross-linkable adhesive compositions. The adhesive compositions include at least a) a rubber latex, at least b) an epoxide and at least c) a polyamine with molecular weight higher than 190 Daltons, including at least two amino groups selected from primary —NH2 and secondary —NH— amino groups. In the structural element, these compositions confer an adhesion between cords and compounds that is comparable to, if not better than, the traditional RFL system in use in this sector. Furthermore, by suitably modifying the compound compositions in the reinforced structural elements and, possibly, also in the other elastomeric components of the tyre, it is possible to manufacture tyres while avoiding the use of toxic chemicals, such, as resorcinol and formaldehyde.

摘要： A tyre for heavy load vehicle wheels includes a carcass structure, a belt structure arranged in a radially outer position with respect to the carcass structure, and a tread band arranged in a radially outer position with respect to the belt structure. The belt structure includes a plurality of reinforcing cords, wherein each cord includes a core made of non-metallic material, and a plurality of metallic wires substantially parallel to one another and helically wound around said core with a predetermined winding pitch. The metallic wires are arranged around the core so that, in any cross section of the cord, they are located at just an angular portion of an ideal circumference that circumscribes the core. The cord, when subjected to variable loads of between 10% and 40% of the ultimate tensile strength thereof, undergoes an elongation that varies according to a curve having, in a load-percentage elongation graph, a linear correlation coefficient lower than about 0.990, the points of said curve being interpolated by a straight line having an angular coefficient lower than about 30. The reinforcing cords can be provided in a stone-guard layer and/or in the main belt layers of the belt structure.
摘要翻译：一种用于重载车轮的轮胎包括胎体结构，相对于胎体结构布置在径向外侧位置的带结构以及相对于带结构布置在径向外侧位置的胎面带。带束结构包括多个加强帘线，其中每个帘线包括由非金属材料制成的芯和多个基本上彼此平行的金属线，并以预定的绕线间距螺旋缠绕在所述芯上。金属线布置在芯部周围，使得在线的任何横截面中，它们仅位于围绕芯部的理想周长的角度部分。当经受其极限拉伸强度的10％至40％之间的可变载荷时，帘线经历伸长率，其根据在负荷百分比延伸图中具有低于约0.990的线性相关系数的曲线而变化，所述曲线的点由具有低于约30°的角度系数的直线内插。加强帘线可以设置在带状结构的石材保护层和/或主带束层中。
