Description

Technical Field

[0001] The invention belongs to the technical field of tires, and in particular relates to a tire with a carcass cord and a belt cord braided composite structure and a manufacturing method thereof. Background Art

[0002] Tires are mainly composed of skeleton materials and rubber, and are typical cord-rubber composite materials. The cord, as a reinforcement phase, mainly bears the load of the entire structure, and the rubber, as a matrix, plays a role in transferring the load. The skeleton material of the tire mainly includes two parts: the carcass and the 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 skeleton material determines the tire's load-bearing capacity, rigidity and other properties.

[0003] Chinese patent CN202322892528.1 discloses a tire with a woven belt structure. The belt of the tire is made of steel wires cross-woven into a mesh and then attached with glue, which solves the technical problems of insufficient connection strength and insufficient stability of the double-layer structure of the belt in the current tire; however, this woven belt will produce many cutting points, resulting in holes and cracks in this area in the early stage of use. Under the action of large loads, the belt and the carcass structure will be delaminated, greatly reducing the service life of the tire; and because the stiffness of the cord in this area is discontinuous, it seriously restricts the load-bearing capacity of the tire.

[0004] Therefore, how to provide a tire having a carcass cord and belt cord braided composite structure and a manufacturing method that effectively improves the rigidity and load-bearing capacity of the tire and prolongs its service life has become an issue that technical personnel in this field need to consider. Summary of the invention

[0005] In view of the problems existing in the above-mentioned prior art, the present invention discloses a tire having a carcass cord and a belt cord braided composite structure and a manufacturing method thereof. The present invention can greatly improve the rigidity and load-bearing capacity of the tire and extend the service life of the tire. The present invention specifically discloses the following technical solutions:

[0006] A tire with a carcass cord and belt cord braided composite structure, comprising a carcass cord and belt cord braided composite structure, the carcass cord and belt cord braided composite structure comprising carcass cords and belt cords, the carcass cord and belt cord braided composite structure is a composite structure formed by weaving carcass cords and belt cords together, the carcass cord and belt cord braided composite structure is coated with a wire ring structure, a lower triangular rubber layer, and an upper triangular rubber layer in sequence from inside to outside, the carcass cord and belt cord braided composite structure is provided with an airtight layer, a wire ring cloth layer, and a bead protective rubber layer in sequence on the inside, and the carcass cord and belt cord braided composite structure is provided with a shoulder pad rubber layer, a sidewall rubber layer, and a tread layer in sequence on the outside.

[0007] Furthermore, the carcass cord and belt cord braided composite structure is obtained by braiding the carcass cord and the belt cord using a plain weaving method and then dipping them in glue.

[0008] Furthermore, when the carcass cord and belt cord braided composite structure is woven by the plain weaving method, the carcass cord is used as the weft and the belt cord is used as the warp, and the warp and weft are woven in an alternating and overlapping manner.

[0009] Furthermore, the carcass cord and belt cord braided composite structure comprises plain weave, twill weave and / or satin weave when woven in a plain weave form.

[0010] Furthermore, the carcass cords and belt cords in the carcass cord and belt cord braided composite structure are made of steel wire, nylon, aramid or nylon-aramid mixed material.

[0011] A method for manufacturing a tire having a braided composite structure of carcass cords and belt cords, comprising the following steps:

[0012] S01, selecting a belt cord with the same length as the belt cord layer and a carcass cord with the same length as the carcass cord layer, respectively using them as the warp and weft of plain weaving, setting the spacing between each section of the warp and weft, weaving them symmetrically, and then dipping them in glue to form a carcass cord and belt cord braided composite structure cord; then curling them to connect the two ends of the belt cord to form a carcass cord and belt cord braided composite structure;

[0013] S02, successively attaching the airtight layer, the steel bead covering layer, and the bead protecting rubber layer from the inside to the outside on the lower surface of the carcass cord and belt cord braided composite structure, fixing the steel bead structure and the lower triangle rubber layer and the upper triangle rubber layer on the upper surface of the carcass cord and belt cord braided composite structure, reversely wrapping the steel bead structure and the lower triangle rubber layer and the upper triangle rubber layer, and finally pressing, curling, and forming to form a tire blank with a tire contour;

[0014] S03, sequentially laminating a tire shoulder rubber layer, a tire side rubber layer, and a tire tread layer on the tire green structure, and performing heating and pressurizing vulcanization in a vulcanizer, and obtaining a tire structure after vulcanization is completed.

[0015] The beneficial effects of the present invention are as follows: the present invention adopts a composite structure of carcass cords and belt cords woven together, which is obtained by weaving the carcass cords and belt cords in a plain weaving method and then dipping them in glue. The carcass and belt cords can continuously and evenly transfer loads, ensuring the continuity of the tension of the tire skeleton material, forming a stable force transmission structure, which can greatly improve the rigidity and load-bearing capacity of the tire and extend the service life of the tire.
