Abstract

A snow tire with improved stud hole is provided to prevent the stud from being separated by forming a unit for limiting the movement of the stud due to driving impact. A snow tire with improved stud hole comprises: a tread, a sidewall and a bead portion; a stud hole(1) formed in the tread; a stud inserted into the stud hole; and a driving impact support part(3,31,32) of the stud formed in the stud hole. In the stud hole, an inlet part which is in the opposite side with a driving direction is formed.

Description

스터드 홀 개량 스노우 타이어{Snow tire improved stud hole}Snow tire improved stud hole

본 발명은 스터드를 식입한 자동차용 스노우 타이어에 관한 것으로, 특히, 스터드 홀을 개량한 스노우 타이어에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to automotive snow tires in which studs are implanted, and more particularly, to snow tires with improved stud holes.

타이어에 스터드를 설치하는 스노우 타이어에 있어서는, 타이어의 회전에 의해 발생되는 트레드의 변형과 스터드에 작용하는 원심력 및 충격력에 의하여, 스터드가 타이어에서 이탈되는 현상이 발생되고, 이탈되는 스터드가 증가되면 스노우타이어의 제동 및 견인 성능이 저하된다.In snow tires in which studs are provided on a tire, the phenomenon of the studs coming off the tire due to the deformation of the tread caused by the rotation of the tire and the centrifugal force and the impact force acting on the studs occurs, and when the studs are increased, the snow The braking and towing performance of the tire is degraded.

그리하여 종래에는 스터드의 움직임을 억제하기 위하여 타이어 가류시 스터드를 삽입하여 타이어를 제조하거나 스터드의 형상을 변경시켜서 된 타이어가 제공 된 바 있다. 그러나 이러한 종래의 타이어는 그 제조가 곤란하거나 스터드 이탈 방지 효과가 충분하지 못한 결점이 있다. Thus, in the related art, in order to suppress the movement of the studs, tires have been provided by inserting studs during tire vulcanization to manufacture tires or to change the shape of the studs. However, such a conventional tire has a drawback that its manufacture is difficult or its stud detachment prevention effect is insufficient.

이에 본 발명은, 주행 충격에 의한 스터드의 이탈은 결국 스터드의 움직임에 기인하는 것이라 생각하고, 이러한 스터드의 움직임을 억제하는 수단을 제공함으로서 스터드의 이탈을 방지할 수 있게 하고자 하는 것이다. Accordingly, the present invention considers that the departure of the stud due to the driving impact is attributable to the movement of the stud, and is intended to prevent the departure of the stud by providing a means for suppressing the movement of the stud.

위와 같은 과제, 즉, 스터드의 움직임 억제를 위하여, 본 발명은, 스터드의 움직임 방향부에 스터드의 움직임을 억제하는 버팀부 즉, 스터드를 식입하는 스터드홀에 스터드의 주행충격 대응 버팀부를 형성시킴으로서, 주행 충격에 의한 스터드의 움직임을 억제시켜 스터드의 이탈을 방지할 수 있게 하고자 한다.In order to suppress the movement of the studs, that is, the present invention, by forming a brace portion for suppressing the movement of the stud, that is, the stud hole for inserting the stud in the stud movement direction to the stud hole in the stud movement direction In order to prevent departure of the stud by suppressing the movement of the stud due to the driving shock.

위와 같은 본 발명은 스터드 홀에 형성시킨 버팀부로 인하여 스터드의 움직임에 억제력을 가하게 되고 따라서 자동차의 주행 시 스터드의 움직임이 억제되는 효과를 가지며, 그리하여 스터드의 이탈이 방지된다.The present invention as described above is applied to the restraining force of the stud due to the brace formed in the stud hole has the effect that the movement of the stud is suppressed during the driving of the car, thereby preventing the departure of the stud.

트레드와 사이드월 및 비드부로 구성되고 트레드에 스터드홀(1)이 형성되며, 스터드홀(1)에 스터드(2)가 식입되어 구성되는 자동차용 스노우 타이어에 있어서, 본 발명은 스터드홀(1) 내의 스터드(2)의 움직임 방향부에 스터드(2)의 움직임 을 억제하는 버팀부(3, 31, 32) 즉, 스터드(2)를 식입하는 스터드홀(1)에 스터드(2)의 주행충격 대응 버팀부(3, 31, 32)를 형성시켜서 된 타이어를 제공한다. In a snow tire for an automobile composed of a tread, a sidewall and a bead part and a stud hole (1) is formed in the tread, and the stud (2) is implanted into the stud hole (1), the present invention provides a stud hole (1). The stud 2 travels to the stud parts 3, 31, 32 that suppress the movement of the stud 2, that is, the stud hole 1 into which the stud 2 is implanted, in the direction of movement of the stud 2 in the inner part. The tire which provided the impact responding brace part 3, 31, 32 is provided.

스터드홀(1)에 스터드(2)를 식입하고 주행을 하게 되면 스터드(2)는 스터드홀(1)에 첨부된 도면 도1에 도시된 바와 같이, 스터드(2)가 스터드홀(1)의 벽면에 충격력을 가하면서 그 설치 위치를 움직이게 된다. When the stud 2 is inserted into the stud hole 1 and is driven, the stud 2 is attached to the stud hole 1, as shown in FIG. 1, and the stud 2 is connected to the stud hole 1. The installation position is moved while applying an impact force to the wall.

주행 충격에 의한 스터드(2)의 움직임은 주로 스터드홀(1)의 주행방향반대측입구부(11)와 스터드(2)의 헤드(21)를 수납하는 수납홈의 주행방향측윗턱(12) 및 수납홈의 주행방향반대측 바닥(13)에 주로 가하여 진다.The movement of the stud 2 due to the driving shock mainly includes the running direction opposing side 11 of the stud hole 1 and the running direction upper jaw 12 of the receiving groove which accommodates the head 21 of the stud 2 and It is mainly applied to the floor 13 opposite to the running direction of the receiving groove.

따라서, 본 발명은 위와 같은 스터드홀(1)내에 있어서의 스터드(2) 주행 충격부인 주행방향반대측입구부(11)와 스터드 헤드 수납홈의 주행방향측윗턱(12) 및 수납홈의 주행방향반대측 바닥(13)에 각각 버팀부(3, 31, 32)를 형성시키는 것을 특징으로 한다.Therefore, the present invention is the traveling direction opposite side inlet portion 11, which is the stud 2 traveling impact portion in the stud hole 1, the traveling direction side upper jaw 12 of the stud head receiving groove, and the traveling direction opposite side of the receiving groove. Characterized by forming the braces (3, 31, 32) on the bottom (13), respectively.

버팀부(3, 31, 32)의 형상은 첨부된 도면 도2의 (가), (나) 및 (다)에 도시된 바와 같이, 직다면체형, 반구면형 또는 경사면체형 등 임의의 형상으로 형성시킬 수 있다.The shape of the brace portions 3, 31, 32 is formed in any shape such as a rectangular solid, hemispherical or inclined polyhedron, as shown in (a), (b) and (c) of FIG. You can.

도1은 스터드홀에 설치한 스터드가 주행시에 충격을 받아 스터드홀에 충격력을 가하는 상태 설명도.1 is a diagram illustrating a state in which a stud installed in a stud hole receives an impact when traveling and applies an impact force to the stud hole.

도2는 본 발명의 실시예의 요부 발췌 단면도로서 2 is a cross-sectional view of main parts of an embodiment of the present invention.

(가)는 버팀부의 단면 형상이 직다면체인 실시예를 도시한 것이고, (A) shows an embodiment in which the cross-sectional shape of the brace portion is a straight polyhedron,
