For a better understanding of the present invention, a preferred embodiment of the present invention will be described with reference to the accompanying drawings. The embodiments of the present invention may be modified into various forms, and the scope of the present invention should not be construed as being limited to the embodiments described in detail below. The present embodiments are provided to enable those skilled in the art to more fully understand the present invention. Therefore, the shapes and the like of the elements in the drawings can be exaggeratedly expressed to emphasize a clearer description. It should be noted that in the drawings, the same members are denoted by the same reference numerals. Further, detailed descriptions of well-known functions and configurations that may be unnecessarily obscured by the gist of the present invention are omitted.

Hereinafter, a pneumatic tire for a vehicle according to the present invention will be described in detail with reference to the preferred embodiments of the present invention with reference to the accompanying drawings.

The pneumatic tire T for a vehicle according to the present invention is characterized in that as shown in Fig. 1, among the grooves formed in the tread of the tire, the steering and braking performance enhancement is improved between the opposing blocks 6 in the lateral grooves 4 The supporter 10 is installed.

As shown in Fig. 2, the supporter 10 includes a fixed blade 14 protruding from the supporter 10 such that the supporter 10 can be inserted into the supporter installation groove 12 formed on the side of the opposing blocks 6 in the transverse groove 4 . The supporter 10 is formed with a hollow buffer part 16 formed on both sides of the fixed blade 14 and closely attached to the transverse groove 4 so as to connect the blocks 6 therebetween. That is, the supporter 10 is composed of the fixed blade 14 and the hollow buffer part 16.

The fixed blade 14 is protruded on both sides of the hollow buffer part 16 to support the hollow buffer part 16 grounded on the ground. That is, the fixed blade 14 is formed to have a length that can be inserted into the supporter installation groove 12, and a convex projection 14a is formed at the end so as to be inserted and fixed after being inserted into the supporter installation groove 12. Accordingly, the supporter mounting groove 12 is formed with a concave groove 12a which is coupled to the convex projection 14a at the inner end so as not to be easily separated.

The hollow cushioning portion 16 has a side body 16a formed obliquely on both sides so that the fixed blade 14 protrudes on both sides and is in close contact with the block 6 surface inside the transverse groove 4 . That is, the side body 16a is formed at the same slope as the cross-sectional shape of the transverse groove 4 so as to be closely attached to the transverse groove 4. [ The hollow cushioning portion 16 is formed with a lower end body 16c at a lower portion thereof so as to be connected to both sides of the side body 16a and to be supported on the bottom of the lateral groove 4. [ The lower body 16c is formed thicker than the side body 16a and is inserted into contact with the bottom of the transverse groove 4. [ The hollow cushioning portion 16 is formed with an upper body 16b at an upper portion thereof so as to be connected to both sides of the side body 16a and to be grounded on the ground. The upper body 16b is located above the transverse groove 4 and extends beyond the lower body 16c to connect the two blocks 6. [ The hollow buffer 16 has a hollow portion 16d formed on the inner circumferential surfaces of the upper and lower bodies 16b and 16c and the side body 16a to facilitate absorption and drainage of external force. The hollow portion 16d is formed in such a manner that the upper and lower body portions 16b and 16c and the side body portion 16a can form a certain thickness.

The hollow cushion portion 16 is formed to have a predetermined curvature so as to be grounded on the ground surface in order to improve steering and braking performance as compared with a lower end body 16c formed to have a predetermined curvature so as to be supported on the bottom of the transverse groove 4, And the body 16b is further enlarged. The hollow buffer part 16 is formed in a structure having a height formed from the bottom of the transverse groove 4 to the upper end of the block 6 and a width formed between the blocks in the transverse groove 4 .

It is preferable that the fixed blade 14 and the supporter installation groove 12 are formed at a position higher than the abrasion limit line of the tire so as to promptly inform the abrasion state of the tire. Further, the supporter 10 is made of carbon black having a carbon black content of 50 PHR or more, which is formed of a high-resilience rubber and has good electrical conductivity. The supporter 10 maintains a state in which the supporter 10 is continuously attached to the transverse groove 4 due to the electrical conductivity exerted even when the hollow buffer part 16 except for the fixed blade 14 is worn. That is, even if the hollow buffer 16 partially wears, the supporter 10 relaxes the deformation of the block 6 to improve the steering and braking performance.

On the other hand, in the tread of the tire T, the longitudinal grooves are formed in the circumferential direction and the transverse grooves 4 are formed in the transverse direction perpendicular to the circumferential direction. The block (6) divided by the groove is deformed at the time of steering and braking. The longitudinal grooves forming the blocks 6 and the transverse grooves 4 are provided with the supporter 10 composed of the fixed blade 14 and the hollow buffer 16 in order to alleviate the deformation of the blocks 6, Respectively. That is, when the convex projection 14a of the fixed blade 14 is engaged with the concave groove 12a in the support installation groove 12, the supporter 10 is installed in the groove, And is drained through the hollow portion 16d of the portion 16.

Hereinafter, the installation and operation of the supporter provided in the above-described vehicle air intake tire will be described in detail.

First, when the blocks 6, which are grounded on the surface of the tire T, are deformed, for example, as shown in Fig. 1 of the longitudinal grooves and the longitudinal grooves 4, (10) relaxes the deformation of the blocks (6). That is, the fixing vanes 14 are coupled to the support installation grooves 12 of the blocks 6, so that the supporters 10 receive the action force. In other words, the supporter 10, which is in contact with the blocks 6 that are deformed during steering and braking, absorbs external force by the hollow portion 16d and restrains the blocks 6 from being deformed. Accordingly, braking can be accurately performed as the ground contact area of the blocks 6 with respect to the road surface increases in the braking operation in which steering by the driver's steering operation and load of the vehicle are concentrated.

At this time, even if the steering and the braking are performed on the wet road surface, the water in the ground portion is quickly drained through the hollow portion 16d of the supporter 10 installed in the transverse lube 4. [ Therefore, the steering and braking are performed as intended by the driver by enlarging the ground area by the blocks 6 that are grounded on the road surface.

When the tire T is worn out due to the above-described long-term running, the supporter 10 installed in the groove (longitudinal groove or lateral groove) between the blocks 6, as shown in Fig. 6, And is coupled to the groove 12 by the fixed blade 14, thereby performing the original function and improving the steering and braking performance. 7, even when the supporter 10 is worn in half, the support supporter 10 is coupled to the support installation groove 12 by the fixed blade 14, so that the supporter 10 performs its original function. Thus, the supporter 10 improves steering and braking performance. As shown in FIG. 7, when the supporter 10 is made of a carbon black having a carbon black content of 50 PHR or more and is made of electrically conductive carbon black even when the hollow buffer portion 16 except for the fixed blade 14 is worn in half, It is possible to maintain the state of being attached to the lateral groove 4 by virtue of the electrical conductivity that is generated at the same time as the rubber is formed. In other words, the support 10 formed of the highly elastic rubber containing the carbon black having good electrical conductivity relaxes the deformation of the blocks 6, thereby maintaining the rigidity of the blocks 6, thereby widening the ground area, Thereby improving performance. Also, even when a high load is applied, the supporter 10 improves the performance of the fuel economy by allowing the hollow buffer 16 to buffer the supporter 10 quickly.

7, the supporter 10 is installed on the block higher than the abrasion limit line of the tire even if the hollow cushioning portion 16 except for the fixed blade 14 is worn in half, .

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention. You will know. Therefore, it is to be understood that the present invention is not limited to the above-described embodiments.
