A Carcassconstruct ion of Radial Tire with High Tensile Steel Cord

摘要

The present invention relates to a carcass structure of a radial tire to which a high strength cord is applied.;The carcass of the present invention has a structure of 1 × 0.22 + 18 × 0.20 using a High Tensile (HT) steel cord containing about 0.80 to 0.85% of carbon, which has a diameter of 0.22 mm in one central part. , 18 strand filament diameter outside the center filament is 0.20mm. On the other hand, the cord arrangement per inch of carcass is composed of 13 ~ 17 EPI and the rolled material is 1.9 ~ 2.30mm thick.;The present invention uses a high tensile (HT) steel cord having a carbon content of 0.80 to 0.85% for the carcass structure instead of the carcass code structure using the conventional NT (Normal Tensile) to have a robust durability under high loads and dynamic fatigue. Its purpose is to reduce tire weight by reducing the weight of carcass and the thickness of the rolled product.
