摘要:
A pneumatic radial tire for passenger cars and heavy duty use is disclosed, which tire has a rubber coated steel cord layer in its belt portion. The cord consists of a pair of steel filaments whose preform ratio "K" is set in the range of 2.05-K.sub.1 .ltoreq.K.sub.2
摘要:
A pneumatic radial tire containing a steel cord/rubber composite reinforcement structure wherein the steel cord comprises a plurality of steel filaments embedded in a rubber layer. The steel cord made up of the filaments is flattened out in the form of a generally cross-sectionally flat, oblong, elongated strip having a specified dimensional parameter such that the filaments in the resulting reinforcement are held out of contact with each other and the overall dimensions of the flat cord are uniform throughout the length thereof
摘要:
A pneumatic tire having improved rolling resistance and increased resistance to separation between coat rubber and steel cords embedded therein. The steel cord is formed from two intertwisted steel filaments containing 0.80-0.92 weight percent of carbon. The rubber coat has 100% elastic modulus of 35-55 kg/cm.sup.2. Each of the cords and the rubber coat has a specified mean cross-sectional area (Sa, Sb). The cords are spaced apart from each other by a specified distance across the junction of adjacent belts.
摘要:
A pneumatic radial tire for automotive vehicles comprising a least one rubber coated steel cord consisting of a pair of intertwisted filaments and having a flatness ratio f in the range of 0.6.ltoreq.f .ltoreq.0.9, where f is defined by 2d/h, where d is a diameter of a filament and h is the maximum diameter of the flattened 1.times.2 cord. This cord is obtained by deforming the cord with a force applied transversely and unidirectionally over its length.

摘要:
In a method of the present invention for producing elastomer/steel-wire composite, a steel wire is drawn through a plurality of drawing dies, and the steel wire is coated with an elastomer within 30 secs. after the steel wire passed through the final drawing die. An apparatus of the present invention for producing an elastomer/steel-wire composite comprises a wire drawer for drawing a steel wire through a plurality of drawing dies, and a rubber coater for coating the steel wire with an elastomer, and the coating is completed within 30 secs. after the steel wire passed through the final drawing die.
摘要:
A steel cord for a tire which increases a corrosion resistance and durability and improves the energy efficiency during curing of the tire and a radial tire using the same. This steel cord has an m+n twist structure comprising a core containing m pieces of wires and a sheath containing n pieces of wires, in which a rubber compound or an elastomer compound is filled into a space between the core and the sheath. Otherwise, the steel cord has a 1×N twist structure containing N pieces of wires, in which a rubber compound or an elastomer compound is filled into a space at a cord center surrounded by the N pieces of wires.
摘要:
Highly durable, lightweight tires of a pneumatic radial type for passenger cars are constructed with a tread portion having on its outer peripheral surface a plurality of grooves arranged circumferentially of the tire and a belt layer formed from an array of steel cords and disposed in the tread. Each of the steel cords results from twisting a selected number of steel filaments each of specified contents of C, Si and Ni and has a specified level of tensile strength. The distance of rubber from a bottom end of each of the grooves to an outer surface of the steel cord array is defined to be of a specified range as determined cross-sectionally of the tire.
