Description
본 발명은 타이어, 예를 들면 트럭 내지는 버스에 장착되는 TBR 타이어 내부에서 발생되는 크랙을 감지하는 장치에 관한 것으로, 더욱 상세하게는 타이어 사용중 내부에서 발생되는 크랙을 사전에 감지하여 타이어에 의한 사고를 미연에 방지할 수 있도록 이루어진 타이어의 클랙 발생 감지장치에 관한 것이다.The present invention relates to a device for detecting a crack generated inside a tire, for example, a TBR tire mounted on a truck or a bus. More specifically, an accident caused by a tire is detected by detecting a crack generated inside the tire in advance. It relates to a crack generation detection device of a tire made to prevent in advance.
통상적으로 트럭 및 버스용 타이어인 TBR 타이어에 있어서, 타이어 사용중에 발생가능한 모든 사고의 양상은 여러 가지로 대별될 수 있지만, 그 중에서 벨트부의 크랙에 의한 층간분리 와, 비드부의 크랙은 전체적인 타이어 사고 양상중에서 가장 빈번하게 나타나는 현상이다.In TBR tires, which are typically tires for trucks and buses, all types of accidents that can occur during the use of tires can be classified into various types. This is the most frequent phenomenon.
좀더 부언하면 상기 타이어 벨트부의 구조는 상기 벨트부에서 적층된 4매의 벨트중 제2 벨트와 제3 벨트가 서로 교차각을 가지고 있는바, 이는 타이어가 내부 압력과 적재물의 하중을 지지하고 주행을 할 경우, 이들 층사이에서는 강력한 전단 변형이 발생하게 되며 이로 인해 벨트 층간에는 전단변형에 의한 크랙이 발생하고 이 크랙이 진전되어 분리가 발생하게 되어 있다.In addition, the tire belt part has a structure in which the second belt and the third belt of the four belts stacked in the belt part have an intersecting angle with each other. In this case, a strong shear deformation occurs between these layers, which causes cracks due to shear deformation between the belt layers, and this crack is advanced to cause separation.
그리고 타이어 비드부의 카카스 턴엎 에지(Carcass Turn-up Edge)는 타이어의 내부 압력과 작용하는 수직방향 및 측면방향의 하중에 기인하여 비드코아를 기준으로 카카스는 상하 방향으로 수직 운동을 주로 하게 되는데, 이를 저감시키기 위한 많은 시도가 있어 왔다.And the carcass turn-up edge of the tire bead part is mainly due to vertical and lateral loads acting on the internal pressure of the tire, and the carcass mainly moves vertically in the vertical direction based on the bead core. Many attempts have been made to reduce this.
즉 종래의 타이어는 타이어에 작용된 외력(내압, 하중, 비틀림 등)에 의해 발생되는 크랙이 점진적으로 층간분리 내지는 파열로 이어지기 때문에 이러한 크랙의 발생을 규명하기보다는 주로 저감시키는 방향으로 연구되어 왔었다.In other words, conventional tires have been studied mainly to reduce the occurrence of such cracks rather than to identify them because cracks generated by external forces (inner pressure, load, torsion, etc.) applied to the tires gradually lead to delamination or rupture. .
그러나 타이어의 내부에서 발생하는 크랙의 발생 원인을 규명하기란 쉽지 않을 뿐만 아니라, 실제로 타이어 사고 이후의 양상을 파악하여 그 원인을 역추적하는 방식으로써 사전에 타이어의 내부 크랙 발생 자체를 차단하기란 쉽지 않았다.However, it is not easy to identify the cause of the cracks occurring inside the tire, and it is easy to block the internal crack occurrence of the tire in advance by grasping the pattern after the tire accident and traces back the cause. Did.
이에 본 발명은 상기와 같은 종래 문제점을 감안하여 발명된 것으로, 타이어 내부에서 발생할 수 있는 어떠한 크랙이라도 이를 사전에 감지하여 모니터링 함으로써 발생가능한 사고를 미연에 방지할 수 있는 타이어의 크랙발생 감지장치를 제공함에 그 목적이 있다.Accordingly, the present invention has been made in view of the above-mentioned conventional problems, and provides a crack generation detecting device for a tire that can prevent any accidents by detecting and monitoring any cracks that may occur in the tire in advance. Has its purpose.
상기와 같은 목적을 달성하기 위한 본 발명은 타이어 내부의 벨트부와 비드부의 카카스 접합부에 음향 감지센서를 부착시키고 이 음향 감지센서는 전치 증폭기를 거쳐 차량 운전석에 설치되는 아날로그 처리부와 연결되고 이 아날로그 처리부는 데이타 저장부에 연결된 디지탈 처리부와 연결되면서 이에 연결된 디지탈 출력부로 타이어 크랙 발생시 신호가 디스플레이화 되도록 되어 있다.In order to achieve the above object, the present invention attaches a sound sensor to a carcass junction of a belt part and a bead part of a tire, and the sound sensor is connected to an analog processor installed in a driver's seat via a preamplifier and the analog The processing unit is connected to the digital processing unit connected to the data storage unit and is configured to display a signal when a tire crack is generated by the digital output unit connected thereto.

이하 본 발명을 첨부된 예시 도면에 의거 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
도 1은 본 발명에 따른 타이어의 클랙 발생 감지장치의 전체 구성도이고, 도 2는 본 발명에 따른 음향 감지 센서가 타이어 내부에 부착된 상태도이다.1 is an overall configuration diagram of a crack generation detection device of a tire according to the present invention, Figure 2 is a state diagram attached to the sound detection sensor according to the present invention.
본 발명은 타이어 내부에서 발생하는 크랙을 감지하는 장치에 있어서, 타이어(1) 내부의 벨트부(2)와 비드부(3)의 카카스(4) 접합부에 음향 감지센서(5)를 부착 내장시키고, 이 음향 감지센서(5)는 전치증폭기(6)를 거쳐 차량 운전석에 설치되는 아날로그 처리부(7)와 연결되고, 이 아날로그 처리부(7)는 데이타 저장부(8)에 연결된 디지탈 처리부(9)와 연결되면서 이에 연결된 디지탈 출력부(10)로 타이어 크랙 발생시 신호가 디스플레이화 되도록 이루어져 있다.According to the present invention, in the device for detecting cracks occurring inside the tire, an acoustic sensor (5) is attached to the carcass (4) junction of the belt part (2) and the bead part (3) inside the tire (1). The acoustic sensor 5 is connected to an analog processing unit 7 installed in the driver's seat via the preamplifier 6, and the analog processing unit 7 is a digital processing unit 9 connected to the data storage unit 8. ) Is connected to the digital output unit 10 connected thereto, so that a signal is displayed when a tire crack occurs.
도면중 미설명부호, 12는 아날로그 출력부이다.In the figure, reference numeral 12 denotes an analog output unit.
즉 본 발명은 타이어(1)의 벨트부(2)와 비드부(3)에서 도 1과 같이 크랙(11)이 발생하게 되면, 주행중 타이어에서 방출되는 음향이 상기 음향 감지센서(5)로 전달되고, 이 음향 감지센서(5)는 전치 증폭기(6)와 아날로그 처리부(7)를 거쳐 신호를 디지탈 처리부(9)로 인가시키게 되면, 상기 디지탈 처리부(9)는 데이타 저장부(8)에서 미리 저장된 음의 소스와 이 인가된 음향신호를 서로 비교하여서 그 크기를 데이타화하여 출력하기 때문에 타이어 내부에서 발생된 크랙을 체크하여 일정기간 사용가능한지 혹은 타이어를 교체할 필요가 있는지를 디지탈 출력부(10)로 판단하여 출력하게 된다.That is, in the present invention, when the crack 11 occurs in the belt part 2 and the bead part 3 of the tire 1 as shown in FIG. 1, the sound emitted from the tire while driving is transmitted to the sound sensor 5. When the sound sensor 5 applies a signal to the digital processing unit 9 via the preamplifier 6 and the analog processing unit 7, the digital processing unit 9 is previously stored in the data storage unit 8. Since the stored sound source and the applied sound signal are compared with each other and the magnitude is outputted, the digital output unit 10 checks whether the cracks generated inside the tire can be used for a predetermined time or whether the tire needs to be replaced. It is determined by) and output.
따라서 본 발명은 타이어 내부에서 초기 크랙 발생시 나타날 수 있는 그 어떤 양상에 대해서도 사전에 감지하여 이를 체크할 수 있기 때문에 크랙에 의한 타이어의 벨트 층 분리 내지는 파열에 의한 대형사고를 미연에 방지할 수 있다.Therefore, since the present invention can detect and check in advance any aspect that may occur when the initial crack occurs in the tire, it is possible to prevent a large accident due to the belt layer separation or rupture of the tire due to the crack.
상기와 같이 본 발명에 따른 타이어의 클랙 발생 감지장치는 음향센서를 이용하여 차량 주행중 타이어 내부에서 발생할 수 있는 어떤 크랙도 사전에 감지할 수 있기 때문에 타이어 파손에 의한 사고를 미연에 방지할 수 있는 효과가 있다.As described above, the crack generation detection device of the tire according to the present invention can detect any cracks that may occur in the tire while driving the vehicle in advance by using an acoustic sensor, thereby preventing an accident due to tire damage in advance. There is.
