Description

  The present invention relates to an improvement in the structure of a tire, and more specifically, an improvement to the structure of a rubber layer of a tire, which allows a consumer to conveniently check the safety level of a tire by direct measurement. The present invention relates to a tire wear warning display structure that brings safety concepts and norms to the tire industry.

  As shown in the sectional view of a conventional tire in FIG. 1, the basic structure of a general rubber tire is mainly formed of a carcass layer 10 in an annular shape, and the inner and outer sides of the carcass layer 10 are respectively rubber layers. The carcass layer 10 can employ a steel cord layer or a synthetic fiber cord layer such as nylon or rayon, and the rubber layer 20 is affected by each part depending on the load function of the tire. Depending on the difference in force and function, the rubber material to be selected also differs.

  For example, since the tire surface portion of the tire is in direct contact with the road surface, the rubber material to be used must have excellent wear resistance and at the same time have high heat resistance and antistab performance. Since the sidewall portion of the tire is subjected to relatively large mechanical deformation, the rubber material of the sidewall portion needs to have a relatively low tensile strength and be excellent in fatigue resistance and ozone resistance performance. Since the rubber layer 20 is a part that is in direct contact with the carcass layer 10, the rubber material to be used is strong and between the rubber layer 20 and the carcass layer 10 unless it has high fatigue resistance, heat resistance, and adhesiveness. Two buffer layers 30 cannot be formed.

  The shoulder portion between the tire surface and the sidewall portion of the tire smoothly connects the hard tire surface to the flexible sidewall portion, and concentrates the stress of the shoulder portion under conditions that allow dynamic transition and absorption, Since it must be possible to reduce the risk of detachment of the shoulder, the rubber material selected should have excellent fatigue resistance and adhesion performance. In order to form the bead portion stably, generally, a triangular rubber material having a relatively large hardness or two different hardnesses must be employed to strengthen the bead portion of the tire.

  Since the force and action received by each part of the tire are different, rubber materials with different performances are required, but in principle, the rubber can have the necessary characteristics simply by adding various additives to the rubber raw material. . The characteristics of the rubber material of each part of the rubber tire for different uses are not completely the same, and further, it is not always necessary to classify the rubber material of the part such as the tire surface, sidewall part, shoulder part, etc. In the description, the structure of the rubber layer on the tire surface, sidewall portion, shoulder portion, etc. of the tire will be described as a single “rubber layer 20”.

  In the tire, the rubber layer 20 must have the material characteristics described above, and further, a tread groove 21 of the tire needs to be formed on the tire surface of the rubber layer 20. The main purpose of the presence of the tread groove 21 is to eliminate the water on the tire, and also helps to discharge earth and sand and fine debris, increasing the contact area of the tire and obtaining a better grip. . For this reason, changes in the tread groove depth (from deep to shallow) not only directly affect the running of the vehicle, but also whether the tread groove wear on the entire tire surface is uniform, resulting in abnormal tire pressure. It is possible to determine whether or not there is a tire positioning failure.

  However, the wear safety warning display system currently used for tires only has a "safe wear triangle mark" embedded in the tire surface portion of the rubber layer, and in general, the handle is rotated in one direction. It is necessary to inspect whether the front tire groove is worn down to the “safe wear triangle mark”, so that it is possible to inspect whether the tread groove is within the usable range or the tire needs to be replaced. . The general consumer does not always have such skills and related judgment ability or common sense, and even if the tires are excessively worn, there is a risk of continued use, and even when performing vehicle maintenance, Even though the tires are not yet worn to the standards that need to be replaced, they can be tricked into being replaced by new tyres.

  In view of these problems, the object of the present invention is to provide a tire wear warning, which allows consumers to conveniently check the safety level of a tire by direct eye measurement and bring new safety concepts and norms to the tire industry. It is to provide a display structure.

  The tire wear warning display structure of the present invention improves the structure of the rubber layer of the tire, and is different in color from at least one tire surface portion in the tire rubber layer mainly based on the safe wear condition of the tire. A warning indication layer is provided separately, and the predetermined distance between the warning indication layer and the tire surface is smaller than the tread groove depth of the tire, and the tire wear is reduced before the tire tread groove is worn and flattened. A warning display layer of a predetermined color is exposed to the applied portion depending on the degree of wear.

  This allows consumers not only to conveniently and directly check tire safety levels by visual inspection, but also to prevent tires that have not yet reached the wear standards from being tricked by a bad guy and replaced, Concepts and norms can be brought to the tire industry, and the used tire market and used tire consumption group can be reduced by making it impossible to manufacture used tires by repairing old tires.

  Hereinafter, the structural composition and the overall operation method of the present invention will be described in detail with reference to the drawings.

  The tire wear warning display structure of the present invention is mainly an improvement to the structure of the rubber layer of the tire, allowing consumers to conveniently check the safety level of the tire by direct visual inspection, as well as a new Tire wear warning display structure that can bring safety concepts and norms to the tire industry, and also prevent used tires from being manufactured by repairing using old tires, used tire market and used tire consumption The group can be reduced.

  As shown in FIG. 2, the entire tire mainly includes a carcass layer 10 for forming a main structural shape in an annular shape, and a rubber layer 20 that covers the inside and the outside of the carcass layer 10. As with the conventional product, the carcass layer 10 can adopt a steel cord layer or a synthetic fiber cord layer such as nylon or rayon, and the rubber layer 20 has a different acting force and function at each part, so that the rubber to be selected is selected. The material can also have a difference, and the rubber can have necessary characteristics by adding various additives to the rubber raw material.

  In addition, a tread groove 21 is provided on the tire surface of the rubber layer 20, and the tread groove 21 is used to discharge the accumulated water on the tire, help discharge earth and sand and fine stone chips, and increase the contact area of the tire. A better grip can be obtained. In specific implementation, the buffer layer 30 can be further configured at a position where the rubber layer 20 and the carcass layer 10 are in contact with each other.

  The point of the present invention is to provide a warning display layer having a color different from that of at least one tire surface portion in the tire rubber layer 20 mainly based on the safe wear condition of the tire. Are provided with a first warning display layer 221 and a second warning display layer 222, and these two warning display layers (first and second warning display layers 221 and 222) have different colors and thicknesses, respectively. The predetermined distance between the warning display layer and the tire surface is smaller than the depth of the tread groove 21 of the tire.

  Thus, before the tire tread groove 21 is worn and flattened, as shown in FIG. 3, a predetermined color warning display layer (first warning display layer, When the second warning display layer 221, 222) is exposed and the consumer can conveniently check the safety level of the tire by direct measurement, or if there is a sharp object or nail on the road surface and the tire surface breaks and ruptures In addition, the warning display layer is exposed to warn consumers that there is a risk that the tire is damaged, and it is also possible to prevent a tired person who has not yet reached the wear standard from being deceived and replaced by a bad guy it can.

  In principle, the thinner the warning display layer (first warning display layer 221 in the figure) closer to the tire surface, the better the first warning display layer (first warning display layer 221 shown in the figure) appeared. Bringing new safety concepts and standards to the tire industry with a crisis indication that consumers can realize that the second warning display layer (second warning display layer 222 shown in the figure) will appear in a short period of time In addition, it is possible to prevent the used tires from being manufactured by repairing using old tires, and to reduce the used tire market and used tire consumption group.

  As described above, the present invention provides an excellent wear warning display structure for tires, and applies for a utility model registration here in accordance with the law. The contents of the above description and drawings are based on the best embodiment of the present invention, and are not intended to limit the present invention. Anything that approximates or resembles the structure, apparatus, features, etc. of the present invention is considered to be the present invention.
