Abstract

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pneumatic tire for a vehicle, and more particularly, to a technique for regularly allowing steel cord spacing in semi-finished products such as carcass or belt, including tread (1) and sidewall (2) and In the bead portion 3, the carcass 4 and the belt layer 5 is provided therein, and the steel cord 6 is inserted into the carcass 4 and the belt layer 5. , The nylon cord (7) across the steel cord (6) is installed, the nylon cord (7) is characterized in that to form a knot (71) on each steel cord (6), knot of the nylon cord By maintaining the steel cord spacing uniformly, there is an effect of improving tire durability.

Description

Pneumatic vehicle tire

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pneumatic tire for a vehicle, and more particularly, to a technique for regularly allowing steel cord spacing in semi-finished products containing steel cords such as carcass or belts.

Tires consist of various semi-finished products such as beads, steel chafers, nylon chafers, carcasses, belts, and various rubber extrudates. It is made of green tires on the drum.

When processing semi-finished products using steel cords such as carcass, belt, etc. of heavy-duty tires, irregularities in cord and cord spacing occur due to various problems on equipment or molding machine.

This phenomenon adversely affects the service life and durability of the tires, but current technology does not provide prior art for uniformizing such steel cord spacing.

In other words, it is necessary to prevent the gap between steel cords used in semi-finished products and to make the gap between the cords uniform.

The present invention is to provide a nylon cord across the steel cord, the nylon cord is to provide a tire to form a knot in each steel cord.

According to the present invention there is an effect of improving the tire durability by keeping the knot of the nylon cord of the present invention uniformly without opening the steel cord spacing.

In addition, it improves adhesion performance when rubber topping. Conventionally, topping the rubber to the steel cord (Topping), but when topping the rubber in the application of the present invention nylon cord is to improve the adhesion performance with the rubber. As the steel cord is closely adhered to the topping rubber, the effect of improving tire durability can be expected.

Figure 2 is a perspective view of the main portion of the steel cord and nylon cord of the present invention.
3 is an explanatory diagram illustrating an arrangement state of a steel cord and a nylon cord of the present invention.

The present invention relates to a pneumatic tire for a vehicle, and more particularly, to a technique for regularly stating the spacing of steel cords in semi-finished products such as carcass or belts.

It is composed of a tread (1), sidewalls (2) and bead (3), the carcass 4 and the belt layer 5 is installed therein, the carcass 4 and the belt layer 5 inside In which the steel cord 6 is inserted, the nylon cord 7 crossing the steel cord 6 is provided, and the nylon cord 7 forms a knot 71 on each steel cord 6. It is characterized by.

The knot 71 may be a one-way knot wound once, a cross knot wound in two directions, or the like.

The angle (a) of the nylon cord (7) crossing the steel cord (6) and the steel cord (6) is preferably 90 ± 5 degrees, the interval (d1) between each nylon cord (7) is a steel cord (6) It is preferable that it is larger than the space | interval d2 between ().

Angle (a) of the nylon cord (7) and the steel cord (6) is about 2 degrees difference depending on the position of the semi-finished product in the tire after the vulcanization process, it is preferable to determine the initial set angle in consideration of this.

By uniformly securing the spacing between the steel cords as described above, it is possible to contribute to improving the durability of the tire.
