Abstract
Description
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.

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
Thus, the present invention provides a stud that is formed of a curved rod of outer narrow light. That is, the
