Abstract

PURPOSE:To enhance the non-skid effect on, especially, frozen road by using an non-skid member to be mounted on the outer periphery of tire which is obtained by machining synthetic rubber into threads and weaving into fibers or is formed in cloth due to the technique like bundling, twisting, or interweaving. CONSTITUTION:This anti-skid member is constituted by overlapping in many layers and fixing cloth-like fiber 6 which is obtained by machining synthetic rubber into threads and weaving it into fibers or is formed in cloth due to the technique such as bundling, twisting, or interweaving on a synthetic rubber belt 5 in which fibers like Kepler fiber, glass fiber, carbon fiber, steel fiber, etc., are imbedded as reinforcing material. It is fixed by using the same threads as that used in the synthetic rubber belt 5 and an adhesive. The technique for weaving wool clothes is used as the technique for interweaving the cloth-like fiber 6. At this time, protruded and recessed tread grooves are formed on the surface of interwoven fiber.

Description

TECHNICAL FIELD The present invention relates to a tire structure of an automobile part, and more particularly to a technique for preventing a tire from slipping on a snowy road. [Prior Art] Anti-slip of a conventional car tire is
Generally, there are two main methods. As shown in Fig. 7, by wrapping a metal tire or plastic resin chain around a radial tire that cannot be expected to have an anti-slip function, the grip force on frozen roads is reduced. Was improved and was traveling on a frozen road surface. However, although metal chains have many problems such as vibration, durability, and handling, and plastic resin chains have been considerably improved, mounting them on tires is a major difficulty in terms of handling. In addition, spiked tires, which have a structure that prevents the tires from slipping, cause many cars to run on dry asphalt, causing the spikes to damage the road surface and wind up a large amount of dust, which is a social issue. The usage was restricted and production was discontinued. Instead, tread grooves as shown in Fig. 8 and statless tires with improved rubber have become mainstream, but the function as a slip stopper on fresh snow roads can be almost satisfied, but the effect of slip prevention on frozen road surfaces The drawback was low. [Problems to be Solved by the Invention] A reduction in the anti-slip effect of a statless tire on a frozen road surface is a structure in which a grip force with the road surface is held by pressing snow on the road surface to obtain an anti-slip effect. Since the road surface is already solid on a frozen road surface, the statless tire naturally has a low grip force because it has a structure that presses snow to obtain a grip force. Further, when the tire is loaded on the frozen road surface, the frozen road surface is melted by pressure to generate water as shown in FIG. 5a. Part of it enters the tread groove, (10) of the statless tire, but most of it exists as water between the road contact surface and the frozen surface of the tire. This causes the grip on the road surface to decrease,
The anti-slip function is reduced. INDUSTRIAL APPLICABILITY The present invention maintains the anti-slip effect of the prior art, prevents the reduction of the grip force on the frozen road surface, and realizes a great improvement effect in terms of operability and handling when traveling on the road surface in winter than the conventional anti-slip The purpose is to do. [Means for Solving the Problems] In order to achieve this object, the present invention has invented a tire as shown in FIG. The structure of this tire has the conventional bead wire shown in FIG. 1, and is composed of a radial cord for wrapping the bead wire, a steel belt for reinforcing material, and a Kevlar fiber belt. According to the present invention, the cloth-like fibers of the synthetic rubber belt are sewn into the synthetic rubber belt to obtain gripping power on a frozen road surface and maintain the conventional tire strength. The cloth-like fibers are filamentous and use a reinforcing material such as Kevlar fiber or glass fiber for the core, wrap the reinforcing material with synthetic rubber and make full use of the technique of weaving wool clothing, and using that technology Tread groove can be created and detailed view of part A
When making a convex portion as shown in (1), a front-side technique is used when making a concave portion as in (b). [Operation] A description will be given with reference to FIGS. 5 and 6 by which the effect of the cloth-like fiber as an anti-slip on a frozen road surface can be obtained. First, a description will be given of FIG. 5 in which a conventional statless tire travels on a frozen road surface. Is a frozen road surface, and when the statless tire travels on this road surface, a pressure melting phenomenon occurs as shown by a to melt the ice and generate water. The ice melting phenomenon is likely to occur at temperatures below the freezing point, which is close to 0 degrees. For example, in an environment of 3 degrees below freezing and an environment of 10 degrees below freezing, an environment of 3 degrees below freezing is more likely to occur. (10) is a lot of thin tread grooves which are the features of statless tires,
The water in a partially enters the groove, but much remains as water between the convex portion of the tire and the frozen road surface. Since this water acts as a lubricant, the grip force with the road surface is extremely reduced and a slip phenomenon occurs. Next, a description will be given of FIG. 6 which is a diagram in which a tire having cloth-like fibers applied to the tire surface is run on the road surface described above. Is a frozen road surface, and when a tire provided with the cloth-like fiber runs on this road surface, a pressure melting phenomenon occurs, and the frozen road surface is thawed to become water a. The water at the next moment a is absorbed inside the tire by the capillary phenomenon of the cloth-like fibers. Since the cloth-like fiber of absorbed the dissolved water in the tire, the cloth-like fiber of the is in direct contact with the frozen road surface of so that the grip force between the road surface and the tire does not decrease like a statless tire, and as a non-slip Fulfill the function of.
When the vehicle runs, the water absorbed in the tire is subjected to centrifugal force to the tire to be dispersed as water droplets like b, so that the water absorption of a is not deteriorated. As a measure for maintaining the above-mentioned non-slip function when the cloth-like fiber is worn due to the running of the tire, FIG.
The description of FIG. 3 will be given. FIG. 2 shows a synthetic rubber belt having a structure in which cloth-like fibers are laminated in multiple layers. The reason why the belt has irregularities is to match the groove shape of the cloth-like fiber when forming the tread groove by performing the front knitting and the back knitting of the cloth-like fiber. FIG. 3 shows a synthetic rubber belt, where x is the first layer of cloth-like fibers, y is the second layer of cloth-like fibers, and z is the third layer of cloth-like fibers. In c, the same thread-like material as the cloth-like fibers is sewn to the synthetic rubber belt and the cloth-like fibers in each layer. For example x
It can be seen that even if the first-layer cloth-like fiber of No. 2 becomes worn, the second-layer cloth-like fiber of y becomes the surface, and the non-slip function is fulfilled. The life of this tire is the last when the cloth-like fiber of z which is the last layer comes out, and the slip sign can be displayed by changing the knitting method of this layer with the upper layer. FIG. 4 is an enlarged cross-sectional view of a cloth-like fiber, and a synthetic rubber belt is made of synthetic rubber, and Kevlar fiber or glass fiber is used for the purpose of strengthening the structure as a core material. Embodiments Embodiments will be described below with reference to the drawings. First
The figure is a cross-sectional oblique view of a non-skid tire for an automobile according to the present invention, in which a bead wire, a radial cord, a steel belt, and a Kevlar belt are shown. Therefore, the same reference numerals as those in the figures showing the conventional tires in FIGS. 7 and 8 are used. Is a synthetic rubber belt and Kevlar, glass fiber, carbon fiber steel fiber or the like may be used as a reinforcing material. Is a synthetic rubber thread knitted into a fibrous form and is laminated in multiple layers, and is fixed using the same synthetic rubber thread as for the synthetic rubber belt, or is sprayed with an adhesive to the cloth-like fiber and adhered to the synthetic rubber belt. .
The cloth-like fiber weaving technique is exactly the same as the woolen clothing, and the tread pattern is freely created on the tire surface by utilizing the weaving technique. “A” shown in the details of the A portion is the front stitch of the knitting technique, and the surface is projected.
b is the back of the knitting technique, and the surface is concave.
In addition, a core material of Kevlar fiber or glass fiber is used as a reinforcing material for the synthetic rubber thread. If the fiber diameter is large, the effect on fresh snow can be expected, and if the fiber diameter is thin, the effect on frozen roads can be expected, but the anti-slip effect on fresh snow roads decreases. Further, when the fiber becomes thin, the strength and durability of the fiber are affected. [Effects of the Invention] As described above, the present invention uses a cloth-like fiber in which a thread of synthetic rubber is knitted in place of the conventional tire tread groove, so that slippage on a frozen road surface, which is a drawback of the conventional anti-slip, is prevented. It is an epoch-making non-slip that improves the stopping effect and can maintain the advantages of the conventional anti-slip as it is.
