Abstract

The present invention relates to a tread member for automobile tire manufacturing, wherein the tread member is configured by combining the summer composition part and the winter rubber composition part, by constructing the tread member by mechanically combining the summer rubber composition part and the winter rubber composition part. For example, the rubber composition for the summer contributes to the driving performance on the general road, and the rubber composition for the winter contributes to the driving performance on the snowy surface.

Description

Tread member for vehicle tire manufacturing {Tread member for vehicle tire}

The present invention relates to a tread member for manufacturing tires for automobiles.

   Generally, pneumatic tires are composed of tread and sidewalls on both sides of the tread and beads on both sides of the tread, and the carcass is the main skeleton. It consists of bead parts on both ends of carcass.

  The tread part, which is a ground part of most tires, is divided into general tires that focus on driving performance on general road surfaces such as dry or wet roads, and winter tires that focus on driving performance on snow or ice roads. It is manufactured by.

  However, in recent years, so-called four-season tires have been preferred, in which the user demand for use in all climatic conditions with the same rapid and varied climate change is common to all seasons.

   These four season tires generally determine the physical properties of the rubber forming the tread or the shape of the block or rib formed by the groove and the groove formed on the tread surface, and the shape required for the tire for general roads. It is trying to achieve the purpose by combining and adjusting the shape required on the snow surface.

  However, when such conditions yield the required conditions on the general road and adopt the conditions required on the snow road surface, such tires have a drawback that the performance on the general road surface also lacks the performance on the snow road surface.

  That is, the rubber composition constituting the tire has a poor grip performance on road surfaces that are rapidly wet under the temperature of 7 degrees Celsius in summer tires, and the grip composition is greatly reduced due to hardening of the rubber composition on ice road surfaces. May cause problems in the operation and safety of the equipment. On the contrary, in the case of winter tires, the performance of wet road surface is deteriorated under the temperature condition of 12 degrees Celsius or higher, and the grip force is sharply dropped due to the tendency of the soft rubber composition on the dry road surface, which may cause problems and adversely affect the wear performance. Equals

Generally, it is difficult to satisfy Dry / Wet / Snow / Ice driving performance simultaneously with one tread rubber compound, and in satisfying any one of the performances, there is a double rate relationship in which the other performance must be abandoned. Eventually, there is a so-called trade off relationship in which one must give up performance. Therefore, the conventional four season tires have a drawback that is difficult to manufacture with the desired performance.

Accordingly, the present invention is to solve the problem of reducing the degree of performance abandoned in the production of four season tires to provide a tire having a satisfactory performance, respectively, as a tire for a general road or a tire for a snowy road surface. That is, the present invention relates to a pneumatic tire that can improve the stability of the vehicle when the road conditions change due to weather changes, and more particularly, the optimum characteristics of the road conditions change according to the physical properties of the tread, which is the tire ground portion. To achieve this, pneumatic tires with a tread structure in which Dry / Wet / Snow / Ice road performances are harmonized are provided so that the same tires can realize the advantages of the general roads in winter and the ice snow roads in winter. I would like to.

In solving the above problems, the present inventors pay attention to the fact that it is difficult to find the harmony of the performance of the tire that is made to have the same physical properties of the rubber composition constituting the tread as a whole, the tread member and the summer composition part Combining the molten rubber composition part, but by mechanically combining the summer rubber composition part and the winter rubber composition part to constitute a tread member, the summer rubber composition contributes to the running performance on the general road, the rubber composition for the winter season Provides a tire that contributes to the running performance on an ice snow road.

Such a tire to which the tread member of the present invention is applied has an effect of improving the stability of the vehicle when the road condition changes due to weather changes, and the optimum characteristics of the road condition change depending on the properties of the tread, which is a tire ground part. It is possible to provide a tire with a dry / wet / now / ice performance adjusted to achieve the tire performance required in summer and winter to implement the same tire.

2 is a cross-sectional view of a tire to which the tread member of the present invention is applied.
2 is a cross-sectional view of another embodiment of the present invention.

 The present invention, in forming a tread member, is formed by combining the summer composition and the winter rubber composition portion of the two opposing rubber composition as described above, but the rubber composition for the summer and the rubber composition for the winter A tread member is provided.

   In mechanically combining the summer rubber composition and the winter rubber composition, the present invention, as shown in the accompanying drawings, Figures 1 and 2, the summer rubber composition (1) and the winter rubber composition A tread member is formed by alternately stacking portions 2 circumferentially.

   In mechanically combining the summer rubber composition part and the winter rubber composition part, the present invention also, as shown in the accompanying drawings, Figure 3, the summer rubber composition part (1) or winter rubber composition part (2) as a base material to provide a tread member formed by implanting the rubber composition column 21 for the winter season or the rubber composition column 11 for the summer season.

The present invention further goes beyond, the outer portion (A) constitutes a high occupancy ratio of the rubber composition portion (1) for the summer season having suitable characteristics for the summer season, the inside portion (B) is suitable for the characteristics of the snow on the road surface Asymmetry that provides a tread member by forming a high occupancy ratio of the rubber composition 2 for the winter season, and exhibits the optimum grip force complementary to each road condition and temperature conditions to improve driving, braking, handling performance Allows to implement four season tires.
