Abstract

La presente invención se refiere a una llanta neumática que comprende: (a) una capa de armazón que comprende una pluralidad de cables orientados a de 76 a 90 grados con respecto a un plano circunferencial-medio de la llanta, comprendiendo cada uno de los cables dos o más hilos juntos retorcidos entre sí, cada uno de los hilos consiste de una pluralidad de filamentos de aramida, teniendo los cables de la capa de armazón un multiplicador de torsión en la escala de 8 a 10 y una relación de torsión en la escala de 1 a 1.2; y (b) dos o más capas de banda dispuestas radialmente hacia afuera de las capas de armazón, en una región de corona de la llanta, comprendiendo cada una de las capas de banda una pluralidad de cables que consisten de cuando menos dos hilos que comprenden filamentos de aramida y por lo menos un hilo de núcleo que consiste de al menos un filamento de un material seleccionado del grupo que consiste de poliamidas o poliésteres que tienen una estructura que está por lo menos parcialmente orientada de modo que se requiera una fuerza de por lo menos 4 gramos por denier para alargar o estirar el hilo de núcleo hasta 107 por ciento de su longitud inicial, estando los hilos de aramida adyacentes entre si y retorcidos alrededor del hilo de núcleo, pero no estando juntos retorcidos entre sí, el denier del hilo de núcleo en la escala de 5 a 30 por ciento de la suma de los deniers de los hilos de aramida, y los cables de la capa de armazón tienen un multiplicador de torsión en la escala de 5 a 12 y una relación de torsión en los hilos de aramida a la torsión del cable en la escala de 1.0 a 2.0.
