Steel cords for reinforcing rubber articles and radial tires for heavy duty using the same.

摘要

CABLES steel reinforcing rubber articles includes (1) forming a filament PLAIN WAVY, an inner sheath (3) formed around the core POOR five to six filaments (2) and an outer sheath (5) formed around the sheath INTERIOR BY NINE TO TWELVE filaments (4). The inner sleeve (3) and said outer sleeve (5) are twisted SEALS. DIAMETER OF EACH OF THE INTERIOR COVERS FILAMENTOS AND EXTERIOR is not greater than the core filaments, 5D Lessthanequals L Lessthanequals 30D and 1.2 Lessthanequals H LESS THAN OR EQUAL 2.0D, IN WHICH LYH SSON rESPECTIVELY THE LENGTH AND HEIGHT OF WAVE core filament d is the filament diameter of the core and a ratio P3 / P2, between the turnover rate P2 of the inner sleeve (3) AND iNDEX ROTATION P3 of the outer sheath (5) is in 1.4 MARGIN 2.5. Also it discloses a tire RADIAL TIRE full load, employing three STEEL CABLES IN CENTRAL BAND OF THE SAME.
