Definitions

  • the present invention relates to a stud pin and a pneumatic tire provided with the stud pin.
  • Patent Document 1 a structure having a body in a plan view shape and a base in a plan view shape provided at the lower end thereof is known (see Patent Document 1).
  • the distance from the base axis to the two sides is almost uniform.
  • the body also has a trapezoidal shape in plan view, and the degree of adhesion with the pin hole varies. For this reason, when force is applied from the road surface through the edge portion of the body, the pin hole is likely to fall off. For this reason, the sufficient edge effect by the upper edge part of the body with respect to a road surface cannot be expected.
  • This configuration stabilizes the holding state by being in close contact with the inner surface of the pin hole since the body is cylindrical in the state of being mounted in the pin hole of the tire.
  • the pedestal portion has an asymmetric shape, appropriate holding properties in various directions are ensured by changing the mounting direction.
  • the pedestal part has a straight line part, it is possible to prevent positional displacement with respect to the force acting in the rotation direction.
  • it is set as the structure which has appropriate retainability, the edge effect by the upper-end outer periphery part of a body can fully be exhibited.
  • the pedestal portion has inclined portions that are inclined from both sides in the horizontal axis direction toward the vertical axis.
  • the holding properties can be made different between the first region and the second region, and the mounting direction to the pin hole can be freely selected according to the difference in the shape of the body, the use location, and the like. .
  • FIG. 2 is a development view of a tread portion of a tire to which the stud pin shown in FIG. 1 is attached. It is sectional drawing of the pin hole shown in FIG. It is a top view of the stud pin concerning other embodiments. It is a top view of the stud pin concerning other embodiments.
  • the shaft 5 that collides with the road surface is composed of two stages, and the directions of the peripheral sharp edges are different between the first protrusion 14 and the second protrusion 20 except for one point. Therefore, the edge effect can be sufficiently exhibited. That is, if it goes straight, the 1st edge part 15 will act on a road surface (ice surface). Further, when cornering traveling on a curve, the second edge portion 16 or the third edge portion 17 prevents a lateral deviation with respect to the road surface. Further, when the brake is stepped on, the fourth edge portion 18 and the fifth edge portion 19 apply a braking force to the road surface.
