Embodiment Construction

[0168] Hereinafter, the expression "is located in the radial direction" and "the radial direction" or "radially outer" refers to the axis of rotation along the radial direction "." And "Rotate the axis of rotation from the tire along the radial direction".

[0169] figure 1 Only a half view of the tire is drawn, the tire extends symmetrically with respect to the axis XX ', the axis XX' represents the circumferential plane or equally-equipped plane of the tire.

[0170] exist figure 1 In the tire 1, the tire 1 includes a radial carcass reinforcement, wherein the radial carcass reinforcement is composed of a single ply 2 of the metal steel cord, the carcass reinforcement anchoring in each bead; the bead Not shown figure 1 middle. The carcass reinforcement is covered by the crown reinforcement 3 radially outside, the crown reinforcing member 3 including:

[0171] - The first "triangular" crown curtain layer 30, the first "triangulation" crown curtain layer 30 is formed of a metal st...

Abstract

The invention relates to a rubber composition based on at least one elastomer matrix comprising at least one diene elastomer, at least one reinforcing filler, at least one plasticizing resin, at least one cobalt salt and at least one sulfur vulcanization system, the invention relates to a rubber composition comprising at least one reinforcing filler predominantly comprising carbon black and comprising at least one reinforcing inorganic filler, a plasticizing resin having a glass transition temperature of greater than or equal to 20 DEG C, and a dispersed Z fraction of the reinforcing filler of the rubber composition in the elastomer matrix of greater than or equal to 85. The invention also relates to a reinforced product comprising at least one steel reinforcing element at least partially coated with a metal coating and a rubber composition as defined above in which the reinforcing element is embedded. The invention also relates to a tyre comprising such a composition and / or such a reinforcing product.

Description

Technical field [0001] The field of the present invention is a domain based on diene elastomers, enhances filler and organic cobalt salt; these rubber compositions are particularly intended to manufacture enhanced products and manufacturing tires. Background technique [0002] The rubber composition based on diene elastomers, carbon black and organic cobalt salt is typically used in rubber articles (e.g., tires, conveyor belts, or conveyor belts) because these rubber compositions have good adhesion to the metal components in these articles. . In the tire, these rubber compositions are particularly useful in constituting various inner layers (e.g., enhanced ply), and may also be referred to as coating compositions. [0003] In particular, various reinforcing ply layers of the belt layer of the sub-tire are known, including a metal reinforcement in the form of a steel cord, the steel cord being composed of a thin wire wire assembled together by woven or twisting; these metals The s...
