Abstract

Un neumático (100) para ruedas de vehículos, compuesto por una estructura de carcasa (101), una estructura de cinturón cruzada (106) dispuesta en una posición radialmente exterior con respecto a la estructura de carcasa (101), una capa de refuerzo de cero grados (106c) dispuesta en una posición radialmente exterior con respecto a la estructura de cinturón cruzada (106) y una banda de rodadura (10) dispuesta en una posición radialmente exterior con respecto a la capa de refuerzo de cero grados (106c). La estructura de cinturón cruzada comprende una primera capa de cinturón (106a) y una segunda capa de cinturón (106b) dispuesta en una posición radialmente exterior con respecto a la primera capa de cinturón (106a). Al menos una de las capas de cinturón (106a, 106b) comprende una pluralidad de cordones de refuerzo híbridos (10), cada uno de las cuales tiene un núcleo (11) hecho de un material textil de alto módulo y que se extiende a lo largo de una dirección longitudinal predeterminada (A) y una pluralidad de alambres metálicos (12) sustancialmente paralelos entre sí y enrollados helicoidalmente alrededor del núcleo (11) con un paso de bobinado predeterminado (P). Los alambres metálicos (12) están dispuestos alrededor del núcleo (11) de manera que, en cualquier sección transversal del cordón de refuerzo híbrido (10), estén ubicados en una sola porción angular de una. circunferencia ideal (C) que circunscribe el núcleo (11). La capa de refuerzo de cero grados (106c) incluye una pluralidad de cordones de refuerzo no híbridos (10c.
