본 고안은 트레드고무층을 3개층으로 형성시켜서 된 자동차용 타이어에 관한 것이다.The present invention relates to an automobile tire formed by forming a tread rubber layer in three layers.
자동차용타이어에는 카카스층을 보호하기 위하여 첨부된 도면 제1도나 제2도의 a에 도시된 바와 같이 벨트가 설치되어 있다.The automobile tire is provided with a belt as shown in a of FIG. 1 or 2 of the accompanying drawings to protect the carcass layer.
그런데 이와 같은 벨트는 일반주행시에는 제1도의 (a)에 도시된 바와 같이 벨트가 설치된 상태 그대로를 유지하게 되나 고속주행시에는 주행원심력에 의하여 제1도의 (b)에 도시된 바와 같이 벨트의 말단부(Edge)가 변형을 일으키게 되고 따라서 벨트의 말단부에서 벨트층과 고무층의 분리(Separation)현상이 일어나게 되어 타이어가 파손되는 일이 있게 된다.However, such a belt is maintained in a state where the belt is installed as shown in (a) of FIG. 1 when driving in general, but at the end of the belt as shown in (b) of FIG. Edge) causes deformation, and thus, separation of the belt layer and the rubber layer occurs at the distal end of the belt, resulting in damage to the tire.
그리하여 고속주행내구성을 향상시키기 위하여 종래에는 일반적으로 제2도의 (b), (c) 및 (d)에 도시된 바와 같이 벨트말단부에 섬유코드지로된 벨트카바를 설치한다던지, 벨트전체에 걸쳐 섬유코드지로된 벨트카바를 설치한다던지 또는 말단부에 카바를 설치하고 그 위에 또다시 벨트전체에 걸쳐 카바지를 설치하여 왔다.Thus, in order to improve high-speed driving durability, a belt cover made of fiber code paper is generally provided at the end of the belt as shown in (b), (c) and (d) of FIG. A belt cover made of cord paper or a cover part is provided on the end portion, and the cover is installed on the whole belt again.
타이어를 제조함에 있어 이와 같이 섬유코드지를 설치하게 되면 반드시 섬유코드지의 겹침부위가 생기게 되어 섬유코드지를 타이어전면에 균일하게 설치하는 것이 사실상 곤란하므로 타이어의 균일성(Uinformity)을 행하게 되며 따라서 주행시 떨림현상이 발생하는 중대한 결점이 있다. 또한 섬유코드지 설치작업은 생산성으로 저하시키며 타이어제조비용을 상승시키는 결점이 있다.In the manufacture of tires, if the fiber cord paper is installed in this way, the overlapping part of the fiber cord paper will be created. Therefore, it is difficult to install the fiber cord paper uniformly on the front of the tire. Therefore, the uniformity of the tire will be performed. There is a significant drawback that arises. In addition, the installation of fiber cord paper has the disadvantage of lowering productivity and increasing tire manufacturing costs.
그리하여 본 고안은 섬유코드지로 된 카바를 설치하지 아니하고서도 벨트의 말단부가 분리되는 일이 없도록 하므로서 섬유코드지로 된 카바설치에 따르는 위와 같은 기술적 곤란성을 극복하였다. 즉, 본 고안은, 캡트레드와 언더트레드 2개층으로 구성되어 있는 종래의 타이어트레드저부에 쇼어 A 경도가 85내지 97이고, 점탄성물성 중 60℃에서 측정한 동적손실계수(tanδ)가 0.05 내지 0.15인 고무층을 설치하되 이 고무층의 폭이 보강벨트층의 폭보다 커서 벨트층의 전폭을 덮을 수 있게 한 것인바 이와 같은 본 고안을 첨부된 도면에 의하여 설명하면 다음과 같다.Thus, the present invention overcomes the above technical difficulties due to the installation of the cover made of fiber cord paper without preventing the distal end of the belt without installing the cover made of fiber cord paper. That is, the present invention has a Shore A hardness of 85 to 97 at the bottom of a conventional tire tread composed of two layers of a cap tread and an under tread, and a dynamic loss coefficient (tanδ) measured at 60 ° C. in viscoelastic properties is 0.05 to 0.15. The rubber layer is installed, but the width of the rubber layer is greater than the width of the reinforcing belt layer to cover the entire width of the belt layer. The present invention will be described with reference to the accompanying drawings.
카카스층(1)의 외면부에 보강벨트층(2, 21)을 설치하고 언더트레드(3)와 캡트레드(31)를 형성시키며 언더트레드(3)와 보강벨트층(2, 21)사이에 벨트카바(22, 23)를 설치하여서된 것에 있어서, 언더트레드(3)와 보강벨트층(2, 21) 사이에 벨트카바(22, 23)를 트레드하층(4)으로 형성시킨다.Reinforcing belt layers (2, 21) are provided on the outer surface of the carcass layer (1) to form an under tread (3) and a cap tread (31), and between the under tread (3) and the reinforcing belt layers (2, 21). The belt covers 22 and 23 are formed in the lower tread layer 4 between the undertread 3 and the reinforcing belt layers 2 and 21.
이 트레하드층(4)은 쇼어 A경도가 85내지 97이고, 60℃에서 측정한 동적손실계수가 0.05 내지 0.15인 고무로 형성시킨다.The trehard layer 4 is made of rubber having a Shore A hardness of 85 to 97 and a dynamic loss coefficient of 0.05 to 0.15 measured at 60 ° C.
이동적손실계수(tanδ)는 60℃온도조건에서 0.5% 스트레스(Straom)으로 10HZ의 주파수(frequency)로 측정한 수치이며, 온도스위프(Wweep)로 토션타잎(Torsiontype)의 점탄성 측정기를 이용하여 측정한 것이다.The moving loss coefficient (tanδ) is measured at a frequency of 10HZ with 0.5% stress at 60 ° C, and is measured using a torsion type viscoelasticity meter with a temperature sweep. It is.
이와 같이 벨트카바의 상측에 트레드하층(4)을 형성시킴에 있어서는, 트레드를 압출성형할때에 트레드하층(4)을 포함하는 3개층으로 동시에 압출성형시키는 것이 바람직한, 종래와 같이 캡트레드와 언더트레드를 압출성형시킨 후 타이어 성형공정에서 트레드하층용 고무시트를 별도 부착하여 성형시킬 수도 있다.In forming the lower tread layer 4 above the belt cover as described above, it is preferable to simultaneously extrude the three layers including the lower tread layer 4 when the tread is extruded. After extruding the tread, the tread underlayer rubber sheet may be separately attached in the tire forming process.
이와 같이 구성된 본 고안은 벨트말단부를 트레드하층(4)으로 피복시키고, 트레드하층(4)을 형성하는 고무층은 그 경도를 크게하고 발열이 적은 고무로 형성시키므로서 고속주행시에도 벨트말단부가 변형되지 아니하게 하는 효과가 있으며 섬유코드지를 설치함에 의하여 일어나는 규일성(Uniformity)불량으로 인한 떨림현상을 방지할 수 있는 효과가 있다.The present invention constituted as described above covers the belt end portion with the lower tread layer 4, and the rubber layer forming the lower tread layer 4 is formed of rubber having a higher hardness and less heat generation so that the belt end portion does not deform even at high speeds. There is an effect to prevent the shaking phenomenon due to poor uniformity (Uniformity) caused by installing the fiber code paper.
