Abstract: A combined cable comprising a core cable of high-strength synthetic fibers, which take the form of a twisted bundle of monofilaments or a plurality of twisted bundles of monofilaments, and comprising an outer layer of steel wire strands, is characterized in that the bundle or bundles of monofilaments is or are stretched, with a reduction in diameter, and held in this state by a sheathing, in particular a braided sheathing. The extension under strain of the core cable under load is thereby reduced, so that the load distribution between the cross section of steel and the cross section of synthetic material of the cable improves.In order, in the same sense, conversely to make the strain behavior of the layer of strands approximate that of the core cable, the cable has an intermediate layer of an elastic synthetic material into which the steel wire strands are pressed while spaced apart from one another in such a way that the outer layer extends under load, and contracts radially.A strand can be analogously constructed.

Abstract: The object of this invention is to provide a steel cord, which has ultrafine steel filaments with a diameter of 0.04-0.14 mm stranded with each other so as to reinforce a tire carcass, and a radial tire for a passenger car using the same. The steel cord includes one core filament with a diameter of 0.04-0.14 mm and 4-7 sheath filaments, each having a diameter of 0.04-0.14 mm, spirally stranded around the core filament. At this time, the steel cord has a diameter of 0.2-0.5 mm and shear strength of 25-35 kgf. Additionally, each of the sheath filaments has a smaller diameter than the core filament, and the core filament and the sheath filaments are made of the steel filaments. The radial tire includes the tire carcass provided with the steel cord and a topping sheet, and the steel cord is embedded in the topping sheet such that a rubber gauge ratio is 200-500 % and a rubber clearance ratio is 60-250 %. The steel cord has improved physical properties, such as shear strength and durability, to reduce a thickness of a carcass including the steel cord, leading to the reduction of a weight of the radial tire. Furthermore, controlling stability and durability of the radial tire are improved, thereby reducing costs of maintenance of the passenger car.
