Abstract

Neumático de altura H sobre llanta, que comprende, al menos, una armadura (1) de carcasa radial, formada por, al menos, una tela de elementos de refuerzo inextensibles y anclada en cada talón B por una varilla (2), para formar una vuelta (10) cuyo extremo está situado a una distancia radial HRNC de la base D del talón, estando cada talón B reforzado por, al menos, dos armaduras adicionales de refuerzo, al menos, una primera armadura (6) formada por elementos de refuerzo metálicos radiales, y, al menos, una segunda armadura (7) formada por elementos metálicos, que forman con la dirección circunferencial un ángulo alfa tal que 0º <_ alfa <_ 45º, caracterizado porque, vista en sección meridiana, la primera armadura (6) de refuerzo está formada por, al menos, una tela (60) de elementos inextensibles, enrollada alrededor de la varilla (2) de anclaje de la armadura (1) de carcasa en el interior de la citada armadura (1) de carcasa,para formar dos ramales (601, 602), de modo que el ramal (601) axialmente interior, entre el extremo A radialmente inferior de su borde radialmente superior, adyacente a la armadura (1) de carcasa, y su punto de tangencia T con la varilla (2) de anclaje, sigue un trazado AT rectilíneo denominado del camino más corto, y que el extremo radialmente superior del citado ramal (601) axialmente interior esté situado radialmente a una distancia HLI de la base de la varilla D, comprendida entre 0,216 y 0,432 veces la altura H, teniendo el ramal (602) axialmente exterior, situado axialmente en el interior de la vuelta (10) de la armadura (1) de carcasa, su extremo radialmente superior radialmente menos alejado del eje de rotación que el extremo de la vuelta (10) de armadura de carcasa, y estando comprendida la distancia HLE, que separa el citado extremo de la base D de la varilla, entre 0,2 y 0,8 veces la altura HRNC de la vuelta (10) de armadura (1) de carcasa, no estando la segunda armadura (7), de elementos inclinados con relación a la dirección radial, enrollada alrededor de la citada varilla (2) de anclaje y estando dispuesta axialmente al exterior de la vuelta (10) de armadura (1) de carcasa.
