Description

Technical Field

[0001] This utility model relates to the field of semi-steel radial tire technology, specifically a tire with a transition layer structure. Background Technology

[0002] With the development of tire technology, tire companies are facing fierce competition in the market, and their products are constantly being iterated and upgraded. Tire manufacturers are required to continuously improve production efficiency and reduce production costs while ensuring tire quality and performance. Semi-steel radial tires are a new type of tire in which the tire carcass cords are arranged in the radial direction, and there is a buffer layer with cords arranged circumferentially or nearly circumferentially tightly wrapped around the tire carcass.

[0003] The inner liner of a conventional tire consists of two parts: a transition layer and an airtight layer. The airtight layer has excellent air retention, preventing air leakage from the tire and ensuring that the tire maintains its proper shape and pressure, thus maintaining good driving performance. The transition layer improves the adhesion between the airtight layer and the tire carcass cord layers, preventing delamination during driving.

[0004] However, the existing transition layer is heavy and complicated to manufacture, which increases the weight and cost of semi-steel radial tires, and also reduces the production efficiency of semi-steel radial tires.

[0005] Based on this, a tire with a transition layer-free structure is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0006] The purpose of this invention is to provide a tire without a transition layer structure to solve the problems of high cost, heavy weight, and complicated manufacturing of transition layers in the prior art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A tire with a transition layer-free structure includes a ply, a pressure-sensitive adhesive layer disposed inside the ply, an airtight layer disposed inside the pressure-sensitive adhesive layer, shoulder pads disposed on both sides of the top of the ply, and triangular pads disposed at the bottom of both sides of the ply.

[0009] Two reinforcing components are provided on both sides of the fabric layer, and each reinforcing component consists of a reinforcing layer.

[0010] An inner tube assembly is provided on the top of the fabric layer.

[0011] Based on the above technical solutions, this utility model also provides the following optional technical solutions:

[0012] In one alternative: the pressure-sensitive adhesive layer is made of polyester-type pressure-sensitive adhesive material.

[0013] In one alternative: the inner tube assembly includes a steel wire harness layer disposed on top of the ply layer, a cover layer disposed on top of the steel wire harness layer, an inner tube body disposed on top of the cover layer, and inner tube sides disposed on both sides of the inner tube body.

[0014] In one alternative: the wire bundle layer is made of high-carbon steel cord material.

[0015] In one alternative: the outer layer of the inner tube is provided with an outer tire assembly.

[0016] In one alternative: the tire assembly includes a tire body disposed outside the inner tire body, a tread is provided on the top of the tire body, a pattern is provided on the top of the tread, and tire sides are provided on both sides of the tire body.

[0017] In one alternative: a toe opening is provided at the bottom of the outer tire side, and a steel wire ring is provided inside the toe opening.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] This invention eliminates the transition layer structure without altering the airtight layer by using a pressure-sensitive adhesive layer. By applying a polyester-based pressure-sensitive adhesive over the airtight layer to replace the transition layer, the adhesion between the airtight layer and the fabric layer is maintained. At the same time, by removing the expensive transition layer composed of multiple components, costs are reduced and factory production efficiency is improved. Attached Figure Description

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0026] In one embodiment, such as Figures 1-4 As shown, a tire without a transition layer structure includes: a ply layer 1, a pressure-sensitive adhesive layer 11 disposed inside the ply layer 1, an airtight layer 12 disposed inside the pressure-sensitive adhesive layer 11, shoulder pad adhesive 13 disposed on both sides of the top of the ply layer 1, and triangular adhesive 15 disposed at the bottom of both sides of the ply layer 1.

[0027] Two reinforcing components are provided on both sides of the fabric layer 1, and each reinforcing component is composed of a reinforcing layer 14;

[0028] The top of the fabric layer 1 is provided with an inner tube assembly.

[0029] In this embodiment, the internal gas is sealed by the airtight layer 12, the transition layer is replaced by the pressure-sensitive adhesive layer 11 to strengthen the connection between the airtight layer 12 and the ply layer 1, the connection is strengthened by the triangular adhesive 15, and the tire as a whole is strengthened by the inner tube assembly.

[0030] In one embodiment, such as Figure 1 and Figure 2 As shown, the pressure-sensitive adhesive layer 11 is made of polyester pressure-sensitive adhesive material. By replacing the transition layer with the material of the pressure-sensitive adhesive layer 11, the cost and weight are reduced, and the production efficiency is improved.

[0031] In one embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, the inner tube assembly includes a steel cord layer 2, which is disposed on top of the ply layer 1. A cover layer 21 is disposed on top of the steel cord layer 2, and an inner tube body 22 is disposed on top of the cover layer 21. Inner tube sidewalls 23 are disposed on both sides of the inner tube body 22. The steel cord layer 2 is made of high carbon steel cord material. The tire is reinforced by the inner tube body 22 and the inner tube sidewalls 23, thereby reducing the problem of bulges and improving the overall strength of the tire.

[0032] In one embodiment, such as Figure 1 and Figure 4As shown, the outer layer of the inner tube 22 is provided with an outer tire assembly, which includes an outer tire body 3. The outer tire body 3 is disposed on the outside of the inner tube 22. The top of the outer tire body 3 is provided with a tread 31, and the top of the tread 31 is provided with a pattern 32. The two sides of the outer tire body 3 are provided with outer tire sidewalls 33, and the bottom of the outer tire sidewalls 33 is provided with a bead 34. A steel wire ring 35 is provided inside the bead 34. The tread pattern 32 on the top of the tread 31 provides an anti-slip effect. The tire is installed by connecting the bead 34 to the rim, and the bead 34 is reinforced by the steel wire ring 35.

[0033] The above embodiments disclose a tire without a transition layer structure. In this tire, a polyester-based pressure-sensitive adhesive layer 11 replaces the original transition layer, thereby connecting the ply layer 1 and the airtight layer 12. This eliminates the need to alter the airtight layer 12, thus replacing the original transition layer structure with a polyester-based pressure-sensitive adhesive applied over it. This ensures good adhesion between the airtight layer 12 and the ply layer 1, while reducing costs by eliminating the expensive transition layer composed of multiple components. To improve factory production efficiency, the toe opening 34 is reinforced by the steel wire ring 35 inside the toe opening 34. The tire is installed by connecting the toe opening 34 to the wheel hub. The tire sidewalls are reinforced by the reinforcing layers 14 on both sides of the cord layer 1. The tire shoulders are cushioned by the tire shoulder pads 13 on both sides of the top of the cord layer 1. The tire without a transition layer structure is reinforced by the cooperation between the inner tube body 22 and the outer tube body 3, as well as the inner tube sidewall 23 and the outer tube sidewall 33, thus avoiding the problem of decreased tire stability caused by removing the transition layer.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application.
