Abstract

PURPOSE: A stud of a snow tire is provided to improve the braking and pulling force of a tire on the ice road through increasing the sticking depth of a tire into the ice road by increasing the external pressure on a tire by comprising improved structure. CONSTITUTION: A stud of a snow tire is composed of a bar(1). The outside end of the bar is formed smaller and the inside end of the bar is formed bigger. The bar is formed into bent shape and the body of the bar comprises a water pressure surface. The water pressure surface receives the pressure occurred through the contact of a tire and the ground.

Description

Stud for snow tire

The present invention relates to a stud installed in a snow tire.

In the manufacture of winter stud tires, defects due to cracks in the stud holes make it difficult to meet the product's delivery time and cause significant losses for the company. Most of the cracks in the stud holes occur when the tire is removed from the vulcanized mold after vulcanization.

Therefore, conventionally, the inner end of the stud hole forming pin of the vulcanizing mold has been rounded so that the stud hole forming pin can be easily taken out from the stud hole. However, if the inner end is formed round in this way, the stud hole forming pin can be easily pulled out, but there is a drawback that the stud installed in the stud hole is also easily pulled out. In other words, if the stud hole forming pin is easily taken out, the stud is also easily extracted, which makes it difficult to determine the shape of the stud or the stud forming pin.

In addition, the conventional studs are in contact with the road surface and the pressured studs are pushed into the inside of the tire, so that the studs are less driven (depth), which is not satisfactory. There was.

Therefore, the present invention allows the pins forming the stud holes to be easily extracted from the stud holes, but the studs installed in the stud holes are not easily extracted, and the pressure to the outward direction from the tire is increased to increase the studs. In order to solve the problem of increasing the amount (depth) to be put on the ice snow road surface to provide a tire that can improve the driving performance on the snow road surface, that is, braking and traction.

In order to solve the above problems, the present invention provides a stud that is formed by a bent rod of outer narrow light.

The present invention as described above, when the stud forming pins embedded in the stud holes are separated from the stud holes of the tire, the pins to be released gently exits along the curved curved surface. And the stud installed in the stud hole receives the pressure acting in the vertical direction from the road surface not only to the top surface of the stud but also to the upper curved surface of the bent body, and finally the pressure received by the stud from the road surface of the stud combined the top surface and the upper curved surface. The large area is accommodated, and this force acts as a pressure that the tire presses the stud downwards, thereby increasing the degree of stud being stuck on the snow surface, thereby improving driving performance on the surface of the snow.

2 is an explanatory diagram showing a state in which a stud of the present invention is inserted into a block of a tread.
3 is a side view of a conventional stud and the stud of the present invention;
4 is a perspective view of another embodiment of the present invention;

The present inventors have conventional studs formed straight as shown in FIG. 3 and attached radially to the tire, so that pressure received from the road surface is concentrated only on the bottom surfaces 101 and 102 of the stud, and the lowest bottom surface. The area of (10) must be narrowly formed in consideration of the ease of detachment of the stud forming pins, so the studs installed therein have been found to have a defect in which the studs are pushed inwards and embedded in the ice snow surface. In addition, the present inventors can allow the stud to accommodate the pressure received from the road surface not only on the bottom (inner end) but also on the side, thereby improving the responsiveness to the vertical pressure of the stud, and further from the stud hole for installing such a stud. A tire that facilitates the production of a tire by facilitating the detachment of the hole forming pin is provided.

Thus, the present invention provides a stud that is formed of a curved rod of outer narrow light. That is, the outer end 11 has a small cross-sectional area and the inner end 12 is formed of a bar 1 having a large cross-sectional area, and the bar 1 is not straight but is bent to form a hydraulic pressure in which the body of the bar 1 is bent. A stud is provided that has a face 13. The bending degree of the rod 1 is preferably an angle (a) formed by the tangent (A) of the partial curved surface inserted into the rod 1 and the tangent (B) of the protruding partial curved surface is 90 to 150 degrees. If this angle is 180 degrees then the bar is straight and outside the scope of the present invention. Fig. 2 shows a state in which the stud of the present invention is inserted into the block 2 of the tread.

Thus, the stud of the present invention can accommodate the pressure received from the road surface not only at the inner end 12, which is the lower surface, but also at the bent hydraulic pressure surface 13 on the side, as shown in FIG. It provides a stud that can be improved in response to pressure.

The rod 1 forming the studs of the present invention may be quadrangular in cross section as shown in the accompanying drawings, and may be any shape such as a polygon, even though a circle.

In addition, it is also possible to configure the locking portion (3) to prevent separation after insertion in the inner end portion 12 portion.

Claims (3)

The outer end 11 has a small cross-sectional area and the inner end 12 is formed of a rod 1 having a large cross-sectional area, and the rod 1 is not straight but curved, so that the body of the rod 1 has a bent hydraulic surface ( 13) studs of snow tires characterized by.
2. The stud of a snow tire according to claim 1, wherein the bending degree of the rod (1) is an angle formed by a tangent (A) of the lower curved surface of the rod (1) and a tangent (B) of the upper curved surface.
2. The stud of a snow tire according to claim 1, wherein a locking portion (3) is formed at the inner end portion (12) to prevent separation after insertion.
