High-strength tire bead steel wire for winter nailless tire and production process of high-strength tire bead steel wire

Abstract

The high-strength tire bead steel wire comprises a steel wire body, the end face of the upper half portion of the steel wire body is in a semi-oval shape, the end face of the lower half portion of the steel wire body is in a triangular shape, a bent groove is formed in the upper side of the steel wire body, and a guide groove is formed in the lower side of the steel wire body. A plating layer is arranged on the outer side of the steel wire main body, and the outer side of the plating layer is coated with an adhesive; according to the high-strength tire bead steel wire for the nailless tire in winter and the production process of the high-strength tire bead steel wire, the section of the steel wire body is arranged to be in the shape of the semi-oval upper portion and the triangular lower portion, the side face area of the device is increased, the blocking effect of the device is improved, and therefore the anti-puncturing performance of the tire is enhanced; when an external article pierces the tire, the pierced article is guided to the side direction of the steel wire, so that the article is prevented from directly puncturing the tire, and the anti-puncturing performance of the tire is further enhanced.

Description

technical field [0001] The invention relates to the technical field of bead wires, in particular to a high-strength bead wire for winter nailless tires and a production process thereof. Background technique [0002] Winter studless tires are specially designed for winter driving roads. The special tread rubber design and pattern design can enhance the grip performance of the tires and ensure the driving safety of the car on wet and slippery roads in winter. [0003] In order to suppress the extension of the bead portion and firmly fix the rim, a bead wire is usually installed inside the tire, but the structure of the common bead wire is relatively simple at present, and it is usually a round steel wire with a copper layer on the surface. During processing and use, the steel wire is easy to slip with the tire rubber, which affects the performance of the tire. At the same time, the side of the common bead wire is relatively narrow, and the blocking effect is relatively weak, r...

Problems solved by technology

[0003] In order to suppress the extension of the bead portion and firmly fix the rim, a bead wire is usually installed inside the tire, but the structure of the common bead wire is relatively simple at present, and it is usually a round steel wire with a copper layer on the surface. During processing and use, the steel wire is easy to slip with the tire rubber, which affects the performance of the tire. At the same time, the side of the common bead wire is relatively narrow, and the blocking effect is relatively weak, resulting in relatively low anti-puncture performance of the produced tire. poor
