    摘要： Provided is an elastomer reinforcement cord in which the problem of stress concentration at an interface between an elastomer and a metal cord is solved and the durability is thereby improved. The elastomer reinforcement cord includes metal filaments (1a) and (1b), and a polymer material (3) having a melting point or softening point of 80° C. to 160° C. The elastomer reinforcement cord has a core (11) and at least one sheath layer (12). In a region surrounded by a line connecting the centers of the metal filaments constituting the outermost sheath layer at a cross-section in a direction orthogonal to an axial direction after vulcanization, when a region occupied by other than the metal filaments is defined as a gap region, the polymer material is contained in this gap region, and a filling rate, which is a ratio of the area of the polymer material, is higher than 120%, taking the area of the gap region as 100%.

    摘要： The invention relates to a pneumatic utility vehicle tire of a radial type of construction, in particular for trucks, buses, and truck trailers, which has a four-ply or multi-ply belt (4) comprising a barrier ply (5), two working plies (6, 8) and a 0° ply (7), wherein steel cords (10) are arranged in the 0° ply (7), comprising at least two strands (11) each with at least 6 steel filaments (12), and wherein twisting causes each strand to have an identical first twist angle α and the steel cord to have a second twist angle β.
    The invention is distinguished in that the steel cord (10) of the 0° ply (7) has the construction 2 to 4×n×d, with n=6 to 8 and with d=0.15 mm to 0.29 mm, wherein this construction means that the steel cord (10) has 2 to 4 twisted-together strands (11), wherein each strand (10) contains 6 to 8 steel filaments (12), in that each steel filament (12) of the steel cord (10) has the same filament diameter (13) and in that the sum of the twist angle α of a strand (11) and the twist angle β of the steel cord lies between 37° and 50°, preferably between 37° and 45°, particularly preferably between 38.5° and 42.5° and most particularly preferably between 39.3° and 41.3°.

    摘要： A steel cord is configured so that, when the steel cord is used as a tensile cord for an elastic crawler, a center-core dislocation and the early breakage of the wires of a core are prevented. A steel cord comprises: a core which comprises a single core strand, and a sheath which is formed by twisting together six sheath strands arranged around the core. The core strand has a layer-twisted structure comprising: a center-core portion which is formed by twisting three core wires together; and an external layer portion which is formed by twisting together eight to nine core wires arranged around the center-core portion. The sheath strands each have either a bundle twisted structure which is formed by twisting twelve to nineteen sheath wires or a multi-layer twisted structure which is formed by twisting twelve to nineteen sheath wires in layers. The diameter (dc) of the core wires is greater than the diameter (ds) of the sheath wi res. The average gap (Gc) between the core wi res of the external layer portion is 0.015 mm or greater, and the average gap (Gs) between the sheath strands is 0.1 mm or greater.
