Description

Technical Field

[0001] This utility model relates to the field of tire structure technology, specifically to an industrial tire with a novel shoulder structure design. Background Technology

[0002] Industrial tires are tires specifically designed for industrial applications. They are characterized by high load-bearing capacity, wear resistance, and cut resistance. They are suitable for industrial vehicles such as forklifts, loaders, and excavators. Industrial tires withstand various compression deformations under various complex and harsh working conditions, as well as high-frequency and high-load forklift torsion operations. Therefore, the tires are required to have high load-bearing capacity, traction, and cushioning performance.

[0003] Industrial tires are typically used for short-distance, continuous operations on paved roads. Tire deformation is mainly concentrated in the tire shoulder and bead area. The tire shoulder of an industrial tire generally consists of tread rubber, cushioning rubber, cushioning layer, tire carcass lines, and inner liner. Due to the very heavy loads carried by industrial vehicles, the tire tread blocks are designed to be larger and deeper to bear the dynamic and static loads of industrial vehicles. However, under high loads and continuous operation, the tire shoulder of this type of tire with large tread block design repeatedly flexes and compresses, causing the tire shoulder temperature to rise sharply. The heat is not easily dissipated, leading to rubber aging and a decline in physical properties. This can easily cause early and mid-term tire shoulder delamination, and in severe cases, tire bursting. This not only threatens the safety of operators but also greatly increases the cost of use. Based on this, a new type of industrial tire with a novel tire shoulder structure design is now proposed, which can eliminate the drawbacks of existing devices. Utility Model Content

[0004] The purpose of this invention is to provide an industrial tire with a novel shoulder structure design to solve the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An industrial tire with a novel shoulder structure design includes an inner liner, a carcass liner layer covering the outer side of the inner liner, a buffer layer covering the outer wall of the carcass liner layer, a buffer rubber sheet covering the outer wall of the buffer layer, a tread rubber layer disposed on the outer side of the buffer rubber sheet, and a low-heat-generating layer disposed between the buffer rubber sheet and the tread rubber layer.

[0007] Based on the above technical solutions, this utility model also provides the following optional technical solutions:

[0008] In one alternative: the outer wall of the tread rubber has a sidewall pattern, and the sidewall pattern is located on one side of the tread rubber.

[0009] In one alternative: the depth of the inner cavity of the sidewall tread pattern is 6-10 mm, and the width of the inner cavity of the sidewall tread pattern is 8-15 mm.

[0010] In one alternative: a shoulder heat dissipation groove is formed on the outer wall of the tread rubber, and the shoulder heat dissipation groove is located at the top of the sidewall tread pattern.

[0011] In one alternative: the inner wall of the shoulder heat dissipation groove is L-shaped, and the inner cavity of the shoulder heat dissipation groove is interconnected with the inner cavity of the sidewall tread pattern.

[0012] In one alternative embodiment: the depth of the inner cavity of the tire shoulder heat dissipation groove is 3-5mm, and the width of the inner cavity of the tire shoulder heat dissipation groove is 8-10mm.

[0013] In one alternative: the low heat generation layer covers the outer wall of the buffer film, the tread rubber covers the outer wall of the low heat generation layer, and the tread rubber is connected to one end of the buffer film.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention effectively reduces tire heat generation and heat concentration in the tire shoulder area through a low-heat layer, sidewall tread pattern, and shoulder heat dissipation grooves. Based on wind tunnel principles, it can dissipate heat from the tire shoulder area during driving, effectively improving the tire's heat dissipation performance and preventing premature tire shoulder delamination caused by excessive tire temperature, thereby further extending the tire's service life.

[0019] 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.

[0021] In this embodiment, during use, the low heat generation characteristics of the low heat generation layer 5 can effectively reduce the heat generation of the tire during tire use by utilizing the specially formulated rubber compound. At the same time, through the sidewall tread pattern 6 and the shoulder heat dissipation groove 7 opened on the side and upper part of the tire shoulder, according to the wind tunnel principle, the heat of the tire shoulder area can be dissipated by the airflow in front during vehicle operation, thereby further improving the heat dissipation effect of the tire shoulder area and effectively avoiding the tire delamination caused by abnormal heat rise in the tire shoulder area during use, thereby further improving the heat dissipation performance of the tire.
