Tire and cable tire bead

Abstract

The invention discloses a cable tire bead. The cable tire bead comprises at least one outer winding layer which is wound in a circumferential direction of the tire, wherein at least one layer in the outer winding layer is a cord ply; and the cord ply comprises at least one cord which is obtained by twisting a plurality of monofilaments. According to the invention, a steel wire structure of partial winding is replaced with a cord structure in the cable tire bead; as the cord is obtained by twisting the plurality of monofilaments, the strength of the cord is higher than that of the steel wire and the weight of the cord is lower than that of the steel wire. Therefore, through replacing the steel wire with the cord in the cable tire bead, the integrated strength of the tire bead can be enhanced and the weight of the tire bead can be reduced. In addition, as the steel wire is replaced with the cord, the adhesive force between the winding and rubber can be also increased and the releasing resistance of the tire bead is increased. The invention further discloses a tire including the cable tire bead.

Description

technical field [0001] The invention relates to the field of tire processing, in particular to a cable bead. Furthermore, the present invention also relates to a tire comprising the above-mentioned cable-type bead. Background technique [0002] The bead refers to the part where the tire is installed on the rim. The bead can withstand the tensile force caused by the internal pressure, and at the same time overcome the lateral force of the tire during cornering, so that the outer tire will not come out of the rim. Therefore, the bead should have high strength, and the structure should be tight and firm, and not easy to deform. [0003] In addition, when the tire is processed, if the adhesion between the bead and the rubber is poor, the bead and the rubber will be separated during the use of the tire to form a gap, causing air, water or other impurities to infiltrate between the bead and the rubber. In the gap between the beads, the bead will be corroded, which will affect th...

Problems solved by technology

[0003] In addition, when the tire is processed, if the adhesion between the bead and the rubber is poor, the bead and the rubber will be separated during the use of the tire to form a gap, causing air, water or other impurities to infiltrate between the bead and the rubber. In the gap between the bead, the bead will be corroded, which will affect the safe use of the tire. Therefore, the adhesion between the bead and the rubber should also be improved.
