On the other hand, the actual vehicle wear test, which is carried out by attaching to a vehicle, is not only time-consuming and expensive, but also causes a problem of data deviation depending on the evaluator and the test conditions (climate / weather, road surface conditions). At present, there is no data to replace the actual vehicle wear test data.
본 발명은 이러한 종래기술의 문제점을 해결하기 위한 것으로서, 실내에서 짧은 시간 내에 적은 비용으로 정확한 마모 데이터를 얻을 수 있는 마모시험기를 제공하는 것을 목적으로 한다.The present invention is to solve the problems of the prior art, and an object of the present invention is to provide a wear tester that can obtain accurate wear data at a low cost in a short time indoors.
도 1은 본 발명에 따른 마모시험기를 개략적으로 나타내는 정면도이다.1 is a front view schematically showing a wear tester according to the present invention.

상기 목적을 달성하기 위하여 본 발명의 마모시험기는, 프레임과, 프레임의 내에 회전 가능하게 설치되는 회전드럼과, 가압수단과, 한쪽은 가압수단에 다른 쪽은 타이어에 연결되어 가압수단의 하중을 타이어로 전달하는 서스펜션과, 측정될 타이어가 장착될 위치의 위쪽에 설치되는 광센서와, 상기 광센서에서 검출한 신호를 타이어의 마모와 관련된 물리량으로 변환하는 수단을 포함하여 이루어지는 실내 타이어 마모 측정기를 제공한다.In order to achieve the above object, the wear tester of the present invention is connected to a frame, a rotating drum rotatably installed in the frame, a pressurizing means, one of the pressurizing means and the other of the tire to load the pressure of the pressing means. And an optical sensor installed above the position on which the tire to be measured is mounted, and means for converting a signal detected by the optical sensor into a physical quantity associated with wear of the tire. do.
이하 본 발명의 실시예를 도면을 참조하여 설명한다.Embodiments of the present invention will be described below with reference to the drawings.
도 1은 본 발명에 따른 마모시험기를 개략적으로 나타내는 정면도이다. 도면에서 부호 6은 프레임으로서 마모시험기를 구성하는 요소들을 수납한다. 프레임의 바닥에는 드럼(1)이 회전 가능하게 설치되어 있다. 이 드럼(1)은 도시되지 않은 제어수단에 의해 그 회전속도가 조절된다. 드럼(1)의 구동은 일반적인 모터 등을 사용한다. 또 드럼(1)의 표면에는 아스팔트나 콘크리트 등을 피복하여 시험 대상 노면의 상태를 만들 수 있다.1 is a front view schematically showing a wear tester according to the present invention. Reference numeral 6 in the figure contains the elements constituting the wear tester as a frame. The drum 1 is rotatably installed at the bottom of the frame. This drum 1 has its rotational speed controlled by control means (not shown). The driving of the drum 1 uses a general motor or the like. In addition, the surface of the drum 1 may be covered with asphalt, concrete, or the like to create a state of the road surface to be tested.
프레임(6)의 상부 안쪽 중앙에는 유압실린더(5)가 설치되어 있다. 이 실린더(5)의 반대편은 서스펜션(3)과 연결되어 있다. 한편 유압실린더(5)와 서스펜션(3) 사이에는, 타이어가 적용될 차량의 차량조건(wheel alignment)과 동일하게 하여 시험을 할 수 있도록 차량조건을 세팅하기 위한 휠얼라인먼트 세팅장치(7)가 추가된다. 따라서 서스펜션(3)은 실제 차량의 전륜과 동일하게 구성되어, 시험하고자 하는 차량조건으로 세팅되며, 유압실린더(5)로부터 하중을 받는다. 그리고 마모시험시에는 타이어(2)가 장착된다.The hydraulic cylinder 5 is provided in the upper inner center of the frame 6. The opposite side of this cylinder 5 is connected to the suspension 3. On the other hand, between the hydraulic cylinder 5 and the suspension 3, a wheel alignment setting device 7 for setting the vehicle condition so that the test can be performed in the same manner as the wheel alignment of the vehicle to which the tire is applied is added. . Therefore, the suspension 3 is configured in the same manner as the front wheel of the actual vehicle, is set to the vehicle condition to be tested, and receives a load from the hydraulic cylinder 5. In the wear test, the tire 2 is mounted.
한편 타이어(2)가 장착될 경우 타이어의 폭방향으로 연장된 가상의 선(도면에 점선으로 표시)이 프레임(6)의 위부분과 만나는 부분에는 광센서(4)가 설치된다. 또 도시되지는 않았으나, 이 광센서(4)에 의해 검출된 신호를 타이어 폭의 마모와 관련된 물성값으로 변환하는 수단이 설치된다. 광센서(4) 및 변환수단은 검사대상 물체로부터 받은 신호를 두께 등의 물리량으로 환산할 수 있는 공지의 광센서이면 된다.On the other hand, when the tire 2 is mounted, an optical sensor 4 is installed at a portion where an imaginary line (shown as a dotted line in the drawing) extending in the width direction of the tire meets the upper portion of the frame 6. Although not shown, a means for converting a signal detected by the optical sensor 4 into a property value associated with wear of the tire width is provided. The optical sensor 4 and the converting means may be a known optical sensor capable of converting a signal received from the inspection object into a physical quantity such as thickness.
이하 상기와 같이 이루어진 마모시험기의 작동에 대해 설명한다.It will be described below the operation of the wear tester made as described above.
서스펜션(3)에 타이어(2)를 장착하고, 유압실린더(5)로 하중을 가하여 타이어(2)가 실제 차량으로부터 받는 것과 마찬가지의 하중을 받도록 한다. 그리고 여러 가지 노면(아스팔트, 콘크리트)이 부착된 드럼(1)을 회전시켜 타이어(2)를 회전시키고, 광센서(4)에서 검출되는 타이어(2)의 마모와 관련된 신호를, 변환수단에 의해 숫자 등 원하는 측정값으로 변환함으로써 타이어(2)의 마모량이나 마모 양상을 측정한다.The tire 2 is attached to the suspension 3, and a load is applied to the hydraulic cylinder 5 so that the tire 2 receives a load similar to that received from an actual vehicle. Then, the tire 2 is rotated by rotating the drum 1 on which various road surfaces (asphalt, concrete) are attached, and a signal related to wear of the tire 2 detected by the optical sensor 4 is converted by the conversion means. The amount of wear and the wear pattern of the tire 2 are measured by converting it into desired measurement values such as numbers.
