Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of tires, and particularly relates to a tire with a carcass cord and belt cord weaving composite structure and a manufacturing method. BACKGROUND

[0002] A tire is mainly composed of framework material and rubber, and belongs to a typical cord-rubber composite material. The cord serves as a reinforcing phase and mainly bears the load of the entire structure, and the rubber serves as a matrix and plays a role in load transmission. The framework material of the tire mainly includes a carcass and a belt layer. The carcass mainly bears the radial tension of the tire, and the belt layer bears the circumferential tension of the tire. Therefore, the framework material determines the load-bearing capacity and rigidity of the tire.

[0003] Chinese Patent CN202322892528.1 discloses a tire with a weaving belt layer structure. The belt layer of the tire is formed by cross-weaving steel wires into a net and then attaching rubber. This solves the technical problems of insufficient connection strength and instability of the double-layer structure of the belt layer in the current tire. However, the weaving belt layer produces many cutting points, which leads to the early appearance of holes and cracks in this area, and under the action of a large load, delamination occurs between the belt layer and the carcass structure, greatly reducing the service life of the tire. In addition, the stiffness of the cord in this area is discontinuous, which severely restricts the load-bearing capacity of the tire.

[0004] Therefore, how to provide a tire with a carcass cord and belt cord weaving composite structure and a manufacturing method that effectively improve the stiffness and load-bearing capacity of the tire and prolong the service life of the tire has become a problem that needs to be considered by those skilled in the art. SUMMARY

[0005] In view of the problems existing in the prior art, the present application discloses a tire with a carcass cord and belt cord weaving composite structure and a manufacturing method.

[0013] S02, sequentially attaching the air tight layer, the ring cover layer and the bead protector layer from the inside to the outside on the lower surface of the tire body cord and belt cord weaving composite structure, fixing the steel wire ring structure and the lower and upper triangular rubber layers on the upper surface of the tire body cord and belt cord weaving composite structure, and inversely wrapping the steel wire ring structure and the lower and upper triangular rubber layers, and finally performing compression, curling and molding to form a tire blank with a tire contour;

[0014] S03, sequentially attaching the shoulder pad rubber layer, the side rubber layer and the tread layer on the tire blank structure, and performing heating and pressurizing vulcanization by using a vulcanizing machine, and obtaining the tire structure after vulcanization.

[0015] The beneficial effects of the present application are that the tire body cord and belt cord weaving composite structure is obtained by dipping after weaving the tire body cord and belt cord by using the plain weaving method, which can make the tire body and belt cord continuously and uniformly transmit the load, ensure the continuity of the tire framework material tension, form a stable force transmission structure, greatly improve the stiffness and load capacity of the tire, and prolong the service life of the tire.
