Description

Technical Field

[0001] The invention relates to the technical field of tires, and in particular to a tire with a continuously woven carcass cord layer. Background Art

[0002] In radial tires, the structure and laying method of the carcass cord layer are crucial to the mechanical properties of radial tires, and will directly affect the strength, load-bearing performance, impact resistance and flexural resistance of the tire. The traditional carcass cord layer is made of cord and rubber strip calendering, cutting and splicing. Continuous cutting points will be generated at the cutting point of the cord layer. Since there is no coating on the cutting section, it cannot be effectively bonded with the rubber, which will cause interface bonding defects in the carcass cutting point area. During the use of the tire, there is shear behavior between the cord cutting point area and the rubber, resulting in holes and cracks in this area in the early stage of use, which greatly reduces the service life of the tire. Due to the discontinuity of the cord in this area, the load-bearing capacity of the tire is seriously restricted.

[0003] In the prior art, there are many ways to deal with the problem of the cutting point of the carcass cord layer, but each has its own defects. Among them, the Chinese patent with publication number CN113246517A discloses a tire belt layer winding process. The patent mentions the carcass winding process, but lacks a specific implementation plan. First, the rubber-coated steel cords between the tire beads are evenly arranged at 90 degrees to the tread centerline, and a single-layer continuous steel wire tube structure cannot be formed at all; secondly, the rubber-coated steel cord winding process ignores the apex rubber component and only considers winding around two steel wire ring components. In theory, there will inevitably be a structural discontinuity area, thereby forming a hole between the carcass cord layers, artificially creating the initial defect in this area, which greatly affects the service life of the tire.

[0004] A Chinese patent with publication number CN205395663U discloses a radial tire with a steel cord winding structure, wherein the carcass ply of the tire is made by continuously winding a rubber-coated steel wire. The winding process described in the utility model also ignores the apex rubber component and only considers winding around two wire ring components. Structural discontinuity areas are bound to appear, thereby forming cavities between the carcass ply layers, artificially creating initial defects in the area and greatly affecting the service life of the tire. Summary of the invention

[0005] The main purpose of the present invention is to provide a tire with a continuously woven carcass cord layer to overcome the technical problems of shortened tire service life and low load-bearing capacity due to cutting points during tire use.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] A tire with a continuously woven carcass cord layer comprises a wire bead skeleton, an apex rubber component and a continuously woven carcass cord layer, wherein the continuously woven carcass cord layer is an endless carcass cord tube formed by continuous zigzag weaving of cords or rubber-coated cords, and the wire bead skeleton and at least a portion of the apex rubber component are located inside the continuously woven carcass cord layer structure.

[0008] Furthermore, it also includes a sidewall rubber layer, a continuously woven carcass cord layer, a belt layer, an upper tread layer, a lower tread layer, a shoulder rubber layer, an airtight layer, a rim cover layer and a tread rubber layer, and the apex rubber component includes a lower apex rubber layer and an upper apex rubber layer;

[0009] The airtight layer is arranged on the inner side of the continuous woven carcass cord layer, the sidewall rubber layer, the belt layer, the shoulder rubber layer, and the wheel cover layer are all arranged on the outer side of the continuous woven carcass cord layer and are all in contact with the continuous woven carcass cord layer, the outer side of the belt layer and the shoulder rubber layer are attached with the lower tread layer and the upper tread layer in sequence, the outer side of the wheel cover layer is attached with the bead rubber layer, the wire ring skeleton and the lower triangle rubber layer are arranged inside the continuous woven carcass cord layer, and the lower triangle rubber layer is coated on the outer side of the wire ring skeleton;

[0010] When the upper apex rubber layer is arranged on the outer side of the continuously woven carcass cord layer, the continuously woven carcass cord layer is a cord tube formed by continuously and evenly arranging cords in a zigzag shape on the lower apex rubber layer and the wire ring skeleton after the cords are coated with rubber;

[0011] When the upper apex rubber layer is arranged inside the continuously woven carcass cord layer, the continuously woven carcass cord layer is a cord tube formed by continuously and evenly arranging the cords in a zigzag shape on the lower apex rubber layer, the upper apex rubber layer and the wire ring skeleton after the cords are coated with rubber.

[0012] Furthermore, the angle between the arrangement direction of a single cord in the continuously woven carcass cord layer and the axial direction of the tire is 0.1° to 3° or -0.1° to -3°.

[0013] Furthermore, after the cords or rubber-coated cords in the continuously woven carcass ply are arranged in a continuous zigzag shape, the starting point and the end point are connected by butt-jointing, overlapping or welding.

[0014] Furthermore, after the cords in the continuously woven carcass ply are coated with rubber and arranged in a continuous zigzag shape, the positions of the generated connection points are determined by finite element analysis or a tension calculation formula. The finite element method is used to calculate the stress distribution of the tire with the continuously woven carcass ply under inflation and load conditions, and the position where the carcass cord stress is the smallest is selected as the position of the cord connection point.

[0015] Furthermore, the thickness of the rubber-coated cords arranged in a zigzag pattern in the continuously woven carcass cord layer is 0.5 to 2 times of the cord diameter.

[0016] Furthermore, when the upper apex rubber layer is disposed on the outer side of the continuously woven carcass cord layer, the upper apex rubber layer is in contact with the continuously woven carcass cord layer, and the lower apex rubber layer is arranged along the circumference of the wire ring skeleton;

[0017] When the upper triangular rubber layer is arranged inside the continuously woven carcass cord layer, the lower triangular rubber layer and the upper triangular rubber layer are sequentially coated on the outer side of the lower triangular rubber layer from inside to outside, and both are arranged circumferentially along the wire ring skeleton and placed inside the woven carcass cord layer.

[0018] Furthermore, when the lower triangular rubber layer is arranged along the circumference of the wire ring skeleton, it extends outward in the radial direction or axial direction of the wire ring skeleton;

[0019] When the lower triangular rubber layer and the upper triangular rubber layer are arranged along the circumference of the wire ring skeleton, both of them extend outwardly along the radial direction or axial direction of the wire ring skeleton.

[0020] Furthermore, the continuously woven carcass cord layer is formed by continuous zigzag weaving of a single rubber-coated cord or a plurality of rubber-coated cords to form a cord belt.

[0021] Furthermore, the cords in the cord belt composed of the plurality of rubber-coated cords are evenly distributed, and the number of the cords is 2 to 8; the width of a single rubber-coated cord is 2 to 4 mm.

[0022] Furthermore, the cords used in the continuously woven carcass cord layer are steel cords, nylon cords, aramid cords, nylon and aramid mixed cords, polyester cords or carbon fiber cords.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] The present invention forms a continuously woven carcass cord layer by arranging the cords in a continuous zigzag shape on the lower apex rubber layer and the wire ring or on the lower apex rubber layer, the upper apex rubber layer and the wire ring skeleton after the cords are coated with rubber. On the one hand, it can eliminate the continuous cutting points generated by the traditional carcass cord layer through the manufacturing processes of calendering, cutting, splicing and the like, avoid the situation that the cutting points cannot be effectively bonded with the rubber due to the lack of coating, prevent the occurrence of holes and cracks at the cutting points during the running of the tire, and prevent the occurrence of damage forms such as the carcass cord being pulled out when the tire is subjected to impact loads; on the other hand, a stable and continuous force transmission structure is established, the force transmission between the carcass and the wire ring is strengthened, the strength of the carcass cord layer is improved, the weight of the tire is reduced, the load-bearing capacity and service life of the tire are improved, and the manufacturing efficiency of the carcass cord layer can also be improved.

[0063] Example 2

[0064] This embodiment provides a method for manufacturing a tire with a continuously woven carcass ply, and the specific steps of the manufacturing method are as follows:

[0065] S1. Arrangement: prepare two wire ring skeletons and fix them in parallel at a certain interval, wrap the lower triangle rubber layer on the wire ring along the circumferential direction, select a steel wire, cover the surface with rubber, reserve a length to fix it on one of the lower triangle rubber layers, and then wrap it on the other lower triangle rubber layer with a certain tension and angle, so that it is arranged in a zigzag shape for 360 degrees along the circumferential direction, and use an extrusion roller to calender the rubber-coated steel wire into a layer, and finally connect the rubber-coated steel wire at the calculated connection point to make a zigzag carcass cord tube;

[0066] S2. Material preparation: preparing other structural layers required for tire production, cutting corresponding lengths of airtight layer, upper apex rubber layer, shoulder rubber layer, sidewall rubber layer, rim cover layer and bead rubber layer, and attaching them to a zigzag carcass cord tube according to the structural size and position of the tire to obtain a semi-finished component of a rubber tire with a continuously woven carcass cord layer;

[0067] S3, molding: filling the semi-finished product component made in step S2 with air at a certain pressure, attaching the belt layer and the tread rubber layer by lamination, and obtaining an unvulcanized green tire of a rubber tire with a continuously woven carcass cord layer;

[0068] S4, vulcanization: the green tire prepared in step S3 is heated and pressurized for vulcanization using a vulcanizer, and after the vulcanization is completed, a tire with a continuously woven carcass cord layer is obtained.

[0069] In this embodiment, the rubber tire is manufactured through four steps of arrangement, material preparation, molding and vulcanization. The rubber-coated steel wires are continuously and evenly arranged in a zigzag shape and calendered on the lower triangle rubber layer 2 and the steel wire ring 1 to form a carcass cord layer. The rubber sheets of the remaining structural layers are attached to the continuously woven carcass cord layer to obtain a semi-finished component of the rubber tire. The belt layer and the tread rubber layer are attached by lamination to obtain an unvulcanized green tire of the rubber tire with a continuously woven carcass cord layer. Finally, the tire is vulcanized to obtain a molded rubber tire. The manufacturing process of the tire is simple and convenient, which can improve the production efficiency of the rubber tire and ensure reliable quality.

[0070] The continuously woven carcass cord layer 5 is internally coated with a wire ring skeleton 1 and a lower triangular rubber layer 2, and is a cord tube formed by continuously and evenly arranging the steel wires in a zigzag shape on the lower triangular rubber layer 2 and the wire ring 1 after being coated with rubber; wherein the two wire ring skeletons 1 are fixed in parallel at a certain interval, and the arrangement direction of a single steel wire forms an angle of 0.1° to 3° or -0.1° to -3° with the axial direction of the tire.

[0071] The width of the cord tape formed by a single steel wire with adhesive is b. The radius of the steel wire ring covered with the triangle adhesive layer can be approximately equal to the contact radius of the rim, which is expressed by R. rim It indicates that the cross section of the wire ring is approximately a circular cross section, and its diameter is d. The number of turns of the cord tape wound on the wire ring is N, which can be calculated according to formula (1); for a single-layer carcass cord layer composed of continuous zigzag arrangement, the spacing between the cord tapes at each end is 2b. For each turn, two sections of cord tape are arranged. In the entire single-layer carcass cord layer, a total of 2N sections of cord tape are arranged in a zigzag shape. Then formula (1) is:

[0072] Formula (1):

[0073] When the tire is formed, the single-layer carcass cord tube will deform and the radius of each part will change, such as Fig.13 As shown, R rim R is the contact radius of the rim, d R is the radius of the tire at its maximum width. m is the maximum radius of the carcass ply after the tire is formed; the density of the steel cord arrangement in the single-layer carcass ply tube composed of continuous zigzag arrangement is expressed by ρ (unit: segment / mm), and the density of the steel cord arrangement in each part of the carcass ply after forming is ρ rim , ρ d , ρ m , as shown in formulas (2) to (4):

[0074] Formula (2):

[0075] Formula (3):

[0076] Formula (4):

[0077] The steps of this embodiment are used to manufacture a tire with a continuously woven carcass cord layer, in which a cord belt composed of a single steel wire coated with rubber or multiple steel wires coated with rubber is continuously and evenly arranged in a zigzag shape on the lower triangular rubber layer and the steel wire ring frame to form a carcass cord tube, thereby establishing a stable and continuous force transmission structure, strengthening the force transmission between the carcass and the steel wire ring, improving the strength of the carcass cord layer, reducing the weight of the tire, and improving the manufacturing efficiency of the carcass cord layer; eliminating the continuous cutting points generated by the traditional carcass cord layer through calendering, cutting, splicing and other manufacturing processes, avoiding the situation where there is no coating on the cutting points and effective bonding with the rubber is avoided, preventing the occurrence of holes and cracks at the cutting points during tire driving, and the occurrence of damage such as carcass cord pulling out when the tire is subjected to impact loads, thereby improving the load-bearing capacity and service life of the tire.

[0078] In another embodiment, a cord tape composed of a single rubber-coated steel wire or multiple rubber-coated steel wires is continuously and evenly arranged in a zigzag shape on the lower apex rubber layer, the upper apex rubber layer and the wire ring skeleton to form a carcass cord tube.

[0079] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
