Description

Tire with wear warning

BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a tire, and more particularly to a tire having an abrasion warning that increases safety and prompts replacement. Background technique

Please refer to FIG. 1A, which is a cross-sectional view of a tire of the prior art; as shown, the basic structure of a general rubber tire is mainly a main structural body formed by the carcass layer 60, and separately in the carcass layer 60. The inner and outer portions are respectively covered with a rubber layer 70; wherein, because the tire has different load functions, the carcass layer 10 may be selected from a rayon layer such as a wire layer or a nylon layer, and the rubber layer 70 is used for each part thereof. The strength and function of the different materials are different.

For example, the tread portion of the tire is directly in contact with the road surface, and the selected rubber material is required to have good wear resistance, and also has excellent heat resistance and stab resistance; the sidewall portion of the tire is because It is necessary to withstand large mechanical deformation, so the rubber of the sidewall portion preferably has a low tensile strength, excellent fatigue resistance and ozone resistance; a portion where the rubber layer 70 directly contacts the carcass layer 60, The selected compound requires additional strength, fatigue resistance, heat resistance and adhesion to form a buffer layer 80 between the size layer 70 and the carcass layer 60.

As for the shoulder between the tread and the sidewall of the tire, the hard tread must be gently connected to the soft sidewall, and the stress of the concentrated shoulder under dynamic conditions can be transferred and absorbed, and the shoulder removal can be reduced. Empty hazard, the selected rubber should have excellent fatigue resistance and good adhesion; and, in order to stabilize the bead, it is generally used by a hardness or two different hardnesses. Triangular strips to strengthen the bead area of the tire.

Although each part of the tire is subjected to different forces and forces, it is necessary to add different properties of the compound, but in principle, the rubber can have the required characteristics by adding various additives to the rubber raw material; The rubber material of each part of the rubber tire is not completely the same, even if it is not necessary to have the rubber material in the tread, the sidewall, the shoulder and the like, so in the description of the present invention, only the tread of the tire The rubber layer structure of the sidewall, the shoulder, and the like is regarded as a single "size layer 20".

In addition to the material properties described above, the rubber compound layer 70 of the tire must also produce the tread 21 of the tire on the tread of the rubber layer 70. The maximum purpose of the tread 21 is to exclude the tire. The accumulation of water also helps to dispose of gravel or fine gravel, thereby increasing the ground contact area of the tire and thus obtaining better grip. Therefore, the change of the tread depth (lighter from the body) will not only directly affect the vehicle, but also the uniformity of the tread wear through the entire tread. Is it not normal, or the tire is not positioned properly.

However, the existing wear safety warning mechanism of the tire is to embed a "safe wear triangle mark" on the tread portion of the rubber layer. Generally, the steering wheel must be turned to either side to check whether the front tire is ground to " The triangular wear mark ", and to check whether the tread is at the usable limit, considering whether to change the tire or not, as far as the average consumer is concerned, it is not completely equipped with such technology, and relevant judgment ability or common sense, which will cause excessive tires. Wear and tear continue to be dangerous, even when the vehicle is being serviced, there are unscrupulous operators who have not worn the tires to the standard that needs to be replaced, and the consumer has to change the tires in a deceptive manner. Please refer to FIG. 1B , which is a structural schematic diagram of another prior art, which is a tire showing the tire track in color according to the Taiwan Patent Application No. 95205145. As shown, the existing tire 82 is The color dye 84 (colorant) is coated over the entire tire 82. However, in actual use, since the color dye 84 cannot be combined with the material of the tire 82, the color dye 84 will fall off or slide in the tire 82. Thus, when the vehicle uses the conventional tire 82, it is easy to cause the danger of driving because the color dye 84 will fall off or slide in the tire 82 to cause the tire 82 to idle or fall off.

Please refer to FIG. 1C, which is a structural schematic diagram of another conventional technology, which is a tire replacement display structure of the Taiwan Patent Application No. 84200342; as shown in the figure, a conventional tire is used for the tread of the tire. The layer 92 is interposed between the top and the bottom of the groove 94, and more than one replacement display layer 96 is provided to enable the tire to clearly change the timing of the replacement by virtue of the replacement of the display layer 96. However, in the case where the tread 98 has not been worn, the replacement display layer 96 between the top and the bottom of the groove 94 is liable to cause the tread 98 or the replacement display layer 96 to fall off due to long use time or environmental factors. Therefore, the user is misjudged by the service life of the tire, resulting in loss of the user.

Please refer to FIG. 1D, which is a structural schematic diagram of another prior art, which is an indication structure for vehicle tire wear in U.S. Patent No. 3,516,467; as shown, the conventional tire has a tread under the tread 102. An indicating structure 104, however, the indicating structure 104 and the tread 102 are made of different materials, so that the indicator structure 104 will not be tightly coupled with the tread 102 when the vehicle is traveling at a high speed or for a long period of time, which may cause the tread. 102 sliding, even peeling, if the tread 102 slides while the vehicle is driving at a high speed, the capacity also causes the vehicle to puncture or overturn.

Therefore, the present invention provides a tire with wear warning, which not only increases the safety of driving, but also clearly prompts the user to change the tire to ensure the safety of the vehicle.

In order to further illustrate the technical means and efficacy of the present invention for achieving the intended purpose of the invention, the specific embodiment, structure, and characteristics of the tire with wear warning according to the present invention will be described below with reference to the accompanying drawings and preferred embodiments. Efficacy, detailed description as follows.

2A and FIG. 2B are cross-sectional views and structural views of a preferred embodiment of the present invention; as shown, the tire with wear warning of the present invention includes a carcass layer 10 and a warning layer. 22 and a rubber layer 20, the warning layer 22 is disposed above the carcass layer 10, the material of the warning layer 2 ² comprises a rubber, a color material and a silicon-containing anti-wear agent, and the warning layer 22 has at least one tread 21 The rubber layer 20 is disposed under the carcass layer 10 and above the warning layer 22, the rubber layer 20 is the same material as the warning layer 11, and the rubber layer 20 is different in color from the warning layer 22.

Since the rubber layer 20 and the warning layer 22 have the same material, for example, the rubber layer 20 and the warning layer 11 are made of rubber, so that the tire can be prevented from being used at a high speed of the vehicle or after a long time of use. The material layer ²⁰ and the warning layer 11 are separated by materials, and by the color of the rubber layer 20 and the warning layer 22, the rubber layer 20 of the tire is worn out to expose the warning layer 22 to prompt the user to replace the tire. It also ensures the safety of vehicles. In addition to providing a convenient way for consumers to check the safety of the tires by direct visual inspection, it is beneficial to the tire industry to enter a new safety concept, the standard tire wear warning structure, and to avoid the use of tire repair to make second-hand tires. The fetal market and second-hand tire consumer groups have declined sharply.

The material of the silicon-containing antiwear agent is one selected from the group consisting of kaolin, calcined high territory or white carbon black, and any combination thereof. Thus, the wear resistance of the warning layer 22 can be improved, and the rubber layer 20 of the tire is worn and the warning layer 22 is exposed, thereby slowing the loss rate of the warning layer 22.

In addition, since the warning layer 22 has at least one tread 21, when the rubber layer 20 covers the warning layer 22, the tread above the rubber layer 20 also has a tread 211. The use of tire tread 211 to remove stagnant water from the tires also helps to remove sand or fine gravel, thereby increasing the ground contact area of the tire for better grip. ,

The invention further includes a buffer layer 30 between the warning layer 22 and the carcass layer 10. Since the carcass layer 10 can be selected to use a layer of rayon or a layer of rayon such as nylon, the layer 20 of the rubber layer can be different because of the force and function of each part. Present the required characteristics. However, the warning layer 22 and the material of the carcass layer 10 are not completely identical, and in order to firmly bond the warning layer 22 and the carcass layer 10, the warning layer 22 and the carcass layer 10 may be added by virtue of the buffer layer 30. The strength of the bond.

The wear warning tire of the present invention further comprises a plurality of metal wires 40 and a plurality of apex rubbers 50. The metal wires 40 are vertically disposed on two sides of the carcass layer 10, and the apex rubber 50 is vertically disposed on the carcass layer 10 On the side, the apex 50 is located above the metal wire 40 and connected to the metal wire 40.

2C, FIG. 2D and FIG. 2E are the schematic diagrams of the tire making process, the raw material mixing diagram and the tread process of the present invention. Since the tire manufacturing is a conventional technique, the details are not described in detail. In the first step, the step S1 is performed to prepare a tread, the step S ^{2 is performed} to form a steel wire layer, and in step S3, a triangular reinforced steel rubber ring is produced.

Before performing step S1, as shown in FIG. 2D, generally, other synthetic compounds such as natural synthetic rubber, carbon, and sulphur are mixed into a rubber raw material, and then, as shown in FIG. 2E, the rubber raw material is pressed into a plate shape and then cooled to produce. The tread of the tire, and then the rubber material is subjected to the tread extrusion process. Therefore, the rubber material is first heated to make the rubber elastic, and the rubber layer 20 required for the tire is pushed out, and the rubber layer 20 is cooled and then cut. Cut to the length required for the tire. And repeating Fig. 2D and Fig. 2E, the rubber raw material is mixed with the coloring material to produce a warning layer 22.

Please refer to FIG. 2F and FIG. 2G together, which is a schematic diagram of a steel wire layer process and a wire layer cutting process. In step S2, the wire nylon wire is first made into a stranded wire, and then the stranded wire is woven into a wire cloth. 114, and the both sides of the steel wire cloth are uniformly coated with rubber to produce a carcass ^1. Next, as shown in Fig. 2G, the carcass layer 10 is cut. \' Please refer to FIG. 2H and FIG. 21 together, which is a schematic diagram of a process diagram of a triangular reinforced steel rubber ring and a tire component assembly. In the process of the triangular reinforced steel rubber ring, the metal wire 40 is first wrapped with the apex rubber 50, and then The metal wire 40 covering the apex 50 is made into a steel wire rubber ring 116. After that, step S4 is performed to set up components. The carcass layer 10, the warning layer 22, the rubber layer 20 and the steel wire rubber ring 116 are combined, and stoned and formed to form a tire.

Please refer to FIG. 3, which is a partial cross-sectional view of another preferred embodiment of the present invention. As shown in the figure, this embodiment is different from the previous embodiment. The warning layer 22 of this embodiment further includes a first warning. The layer 221 and the second warning layer 222, the first warning layer 221 is located above the second warning layer 222, and the colors of the first warning layer 221 and the second warning layer 222 are different. The first warning layer 221 is the same material as the second warning layer 222. The thickness of the first warning layer 221 is smaller than the thickness of the second warning layer 222. The focus of the present invention is mainly to distinguish at least one layer of warning layer 22 different from the color of the tread portion in the rubber layer 20 of the tire according to the safe wear condition of the tire. In the embodiment, the first warning layer 221 and The second warning layer 222 has different colors and thicknesses, respectively, and the thickness of the rubber layer 20 is smaller than the depth of the tread 21, so that the worn portion of the tire is worn before the tire tread 211 is smoothed. The degree of difference reveals the predetermined first warning layer 221 and the second warning layer 222, which not only allows the consumer to directly check the safety degree of the tire by direct visual inspection, and if the surface has sharp objects or nails, the tread is damaged and bursts. It will expose the warning layer and warn consumers that the tires have been damaged and created a danger. It will also prevent the unscrupulous people from being tricked into replacing tires that have not yet reached the wear standard.

In principle, the shallower the thickness of the first warning layer 221, which is closer to the tread, allows the consumer to feel the short-term appearance of the second warning layer 22 shortly after the first warning layer 22 appears, which is beneficial to the tire industry to enter the new The concept of safety, regulation, and even the use of tire repair to make second-hand tires will make the second-hand tire market and the second-hand tire consumer group sharply reduced.
