Title
(EN) RUBBER REINFORCING STEEL CORD AND HEAVY DUTY PNEUMATIC RADIAL TIRE USING THE STEEL CORD
(FR) CABLE D'ACIER DE RENFORCEMENT DE CAOUTCHOUC ET PNEU RADIAL SUPER-RESISTANT COMPORTANT UN TEL CABLE D'ACIER
Abstract
(EN)
A rubber reinforcing steel cord of bundle- and layer-twisted structure, wherein nine steel filaments are arranged around three steel filaments which are wave-formed two-dimensionally in longitudinal direction, and additional 14 steel filaments are arranged and twisted around a bundle-twisted cord formed by twisting all these steel filaments into one part; a heavy duty pneumatic radial tire, wherein the rubber reinforcing steel cord is used as carcass layer cords.
(FR)
L'invention se rapporte à un câble d'acier de renforcement de caoutchouc présentant une structure torsadée en couche et en faisceau, dans laquelle neuf filaments en acier sont disposés autour de trois filaments en acier qui se présentent longitudinalement sous forme ondulée en deux dimensions, et quatorze autres filaments d'acier sont disposés et torsadés autour d'un câble torsadé en faisceau que l'on forme en torsadant tous ces filaments d'acier de façon à obtenir un câble monobloc. L'invention se rapporte à un pneu radial super-résistant dans lequel ce câble d'acier de renforcement du caoutchouc est mis en oeuvre en tant que câble de la couche de carcasse.
