Abstract

본 고안은 벨트 보강재를 갖는 공기입 타이어에 관한 것으로서, 캡플라이를 제1벨트층 에지부 안쪽에서 시작하여 제2벨트층 상부를 거쳐 트레드의 중심에서 약간 떨어진 지점에서 숄더부쪽으로 턴업하여 다시 제1벨트층 에지부의 바깥쪽 일정 지점까지 캡플라이로 덮어 씌움으로써 벨트층을 보강함과 동시에 타이어 중량감소 및 원가절감을 도모한 공기입 타이어이다.The present invention relates to a pneumatic tire having a belt reinforcement, the capply starting from the inside of the edge of the first belt layer to the shoulder part at a point slightly away from the center of the tread over the second belt layer and then again the first It is a pneumatic tire that reinforces the belt layer and at the same time reduces the weight of the tire and reduces the cost by covering it with a cap ply to the outside of the belt layer edge part.

Description

벨트 보강층을 갖는 공기입 타이어Pneumatic tire with belt reinforcement layer

제1도는 본 고안에 따른 벨트 보강층을 갖는 공기입 타이어의 반단면도.1 is a half sectional view of a pneumatic tire having a belt reinforcement layer according to the present invention.

본 고안은 벨트 보강층을 가진 공기입 타이어에 관한 것으로서, 중량 감소, 세퍼레이션을 방지한 것이다.The present invention relates to a pneumatic tire having a belt reinforcement layer, to prevent weight reduction and separation.

요즘은 마이카시대로 차량이 고성능화되면서 상당한 고속 내구력이 요구되고 있다. 고속 내구력을 만족시키기 위해서는 피로 반복 하중에 의해 발열 및 원심력에 의한 벨트부의 변형을 최소화시켜야 하며, 이를 위해 종래에는 제2벨트의 상단을 완전히 덮고 제1벨트 상단 에지부를 덮는 풀캡플라이를 사용하여왔다. 그런데 이는 벨트 상부를 다 덮어야 하므로 원가 상승의 요인이 되었고 중량 절감 측면에서도 바람직하지 못하였다.Nowadays, as the vehicle becomes more efficient, the high speed durability is required. In order to satisfy the high speed durability, deformation of the belt part due to heat generation and centrifugal force due to repeated fatigue loads should be minimized. For this purpose, a full cap fly which completely covers the upper end of the second belt and covers the upper edge of the first belt has been used. However, this caused a cost increase because it had to cover the upper part of the belt and was not preferable in terms of weight reduction.

이러한 문제점을 해결하기 위하여 본 고안에서는 캡플라이를 제1벨트의 에지부 안쪽에서 시작하여 제2벨트 상부를 지나 트레드 중심부에서 쇼울더 부위쪽으로 턴업함으로써 벨트층을 보강함과 동시에 중량 감소 및 원가 절감을 이룬 것이다.In order to solve this problem, in the present invention, the cap ply starts from inside the edge of the first belt, passes over the second belt, and then turns up from the center of the tread to the shoulder portion, thereby reinforcing the belt layer and at the same time reducing the weight and reducing the cost. will be.

이하 벨트 보강재를 가진 공기입 타이어에 대해 첨부도면에 의거하여 상세히 설명한다.Hereinafter, a pneumatic tire having a belt reinforcement will be described in detail with reference to the accompanying drawings.

본 고안의 공기압 타이어는 캡플라이(1)를 제1벨트층(2)의 양쪽 에지부(2a)에서 각각 안쪽으로 15-30㎜(X) 만큼 들어간 한지점(3)에서 시작하여 제1벨트층 에지부(2a)를 지나 제2벨트층(4)을 덮고, 트레드 중심부(5)에서 제1벨트폭(L)의 1/6-1/10 만큼(a) 떨어진 지점(7)에서 숄더부(6) 쪽으로 턴업하여 제2벨트 상부층을 거쳐 제1벨트의 바깥쪽까지 덮어 씌워 된것이다.The pneumatic tire of the present invention is the first belt starting from the one point (3) in which the cap ply (1) is inserted inwardly from both edge portions (2a) of the first belt layer (2) by 15-30 mm (X), respectively. The shoulder at the point 7 that covers the second belt layer 4 past the layer edge 2a and is 1 / 6-1 / 10 of the first belt width L from the tread center 5 It was turned up toward the part 6 and covered up to the outside of the first belt via the second belt upper layer.

이상과 같이 하여 트레드 중앙부에는 캡플라이를 덮지 않고도 벨트 보강에는 영향을 미치지 않는다. 즉, 타이어 주행시 트레드 중앙부에는 큰 힘이 부과되지 않으므로 그 중앙부에는 캡플라이를 씌우지 않아도 강도는 그대로 유지되면서 타이어 중량감소, 원가절감에 기여할 수 있는 것이다.As described above, the belt reinforcement is not affected without covering the cap ply at the center of the tread. That is, since a large force is not imposed on the center portion of the tread when the tire is running, the strength may be maintained while the cap is not covered with the center portion, thereby contributing to tire weight reduction and cost reduction.
