Description

도로 시뮬레이션이 가능한 실내 마모/내구력 시험기{Indoor wear and durability Test machine for road simulation}Indoor wear and durability test machine for road simulation}

본 발명은 타이어의 마모/내구력 시험기에 관한 것으로써, 특히 실제 도로 상황을 재현하여 실외에서 시험하는 것과 동일한 시험결과를 얻을 수 있도록 하는 마모/내구력 시험기에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tire wear / durability tester, and more particularly, to a wear / durability tester capable of reproducing the actual road situation and obtaining the same test results as those tested outdoors.

현재 실내 내구력 시험기는 규정속도로 시험드럼을 회전시키면서 타이어에 일정하중을 가하는 형태로 구성되어 있으며 사고시까지 타이어를 주행시켜 내구력을 평가하게 되어 있고 실내 마모 시험기의 경우 시험드럼에 샌드페이퍼를 부착시켜 타이어를 주행시키고 일정거리 주행 후 타이어의 마모량을 측정하여 마모의 정도를 판단하는 방법을 사용하고 있다.At present, the indoor durability tester is configured to apply a constant load to the tire while rotating the test drum at the specified speed. The tire is operated to evaluate the durability by driving the tire until the accident.In the case of the indoor wear tester, the tire is attached to the test drum by sand paper. After driving and after a certain distance, the tire wear is measured to determine the degree of wear.

그러나, 두 시험기 모두 시험드럼 자체가 실제 도로 상황과 다르며 또한 도로에서 발생할 수 있는 코너링 등의 상황을 재현할 수 없으며 마모 시험의 경우 샌드페이퍼에 마모된 타이어의 고무가 부착되어 떨어지지 않아 일정시간이 지나면 테스트를 할 수 없는 단점이 있고 또한 이를 제거하는데도 많은 문제점이 있다.However, in both testers, the test drum itself is different from the actual road situation, and it is impossible to reproduce the situation such as cornering that may occur on the road. There is a disadvantage that can not be done and there are also many problems in removing it.

상기의 문제점을 해결하기 위하여 안출된 본 발명의 목적은 실제도로상에서와 같이 마모와 내구력 시험을 실내에서 가능하게 하여 시험기간 및 경비를 줄이고 시험 안정성을 확보할 수 있는 실제 도로의 시뮬레이션이 가능한 시험기를 제공함에 있다.An object of the present invention devised to solve the above problems is to enable the wear and durability test in the room as on the actual road tester capable of simulating the actual road that can reduce the test period and cost and secure the test stability In providing.

본 발명의 구성 및 실시예를 도면을 통하여 자세히 설명하겠다.The configuration and embodiment of the present invention will be described in detail with reference to the drawings.

본 발명은 시험드럼을 제작하여 이 시험기드럼(100) 위에 실제 도로와 같은 아스팔트, 콘크리트, 비포장도로를 만들고, 이 시험기드럼(100)을 회전시키면서 타이어(200,300)에 일정한 하중을 가하여 타이어의 내구력 및 마모량을 측정할 수 있도록 되어있다.The present invention is to make a test drum to make the asphalt, concrete, unpaved road, such as the actual road on the test machine drum 100, by applying a constant load to the tire (200,300) while rotating the tester drum 100 and the durability of the tire and It is possible to measure the amount of wear.

본 발명의 구성은 회전축을 연직방향으로 하는 원통회전체 상단의 원평면 상에 다수의 도로상태가 동심원상으로 도포된 시험기드럼(100); 상기 시험기드럼(100)을 회전시키는 구동원; 상기 시험기드럼(100)의 상면위에서 시험되는 타이어(200,300)를 지지하는 타이어지지대(210,310); 및 상기의 모터를 제어하는 제어컴퓨터로 구성되어 있다.The constitution of the present invention comprises a tester drum 100 in which a plurality of road conditions are applied concentrically on a circular plane of an upper end of a cylindrical rotor having a vertical axis of rotation; A driving source for rotating the tester drum 100; Tire support (210,310) for supporting the tire (200,300) to be tested on the upper surface of the tester drum (100); And a control computer for controlling the motor.

시험기드럼(100)은 회전축이 연직방향이 되도록 하여, 원통형상을 하고 있다. 그 상면에 아스팔트, 콘크리트, 비포장상태를 동심원형태로 하여 구현한다.The testing machine drum 100 has a cylindrical shape with its rotational axis in the vertical direction. Asphalt, concrete, unpaved state on the upper surface is realized by concentric circles.

다만, 회전중심에서 소정의 반경내에는 같은 중심각에 대한 원호의 길이가 짧아서 시험되는 타이어(200,300)와 시험기드럼(100) 상면사이의 슬립이 일어나서 정확한 시험이 이루어지지 않으므로 시험하지 않는다.However, because the length of the arc for the same center angle is short within the predetermined radius at the center of rotation, slip between the tires 200 and 300 to be tested and the upper surface of the testing machine drum 100 occurs, so the test is not performed.

타이어(200,300)의 폭을 고려하여 시험기드럼(100)의 각 노면은 폭을 50㎝정도로 하고 시험기드럼(100)의 반경을 5 m로 하여 여러개의 타이어(200,300)를 동시에 시험할 수 있게 한다.In consideration of the width of the tire (200,300), each road surface of the tester drum (100) is about 50cm in width and the radius of the tester drum (100) to be able to test several tires (200,300) at the same time.

시험기드럼(100)을 회전시키는 구동원은 모터를 이용하며, 컴퓨터에 의해 조절이 가능한 서보모터를 사용하는 것이 바람직하다.As a driving source for rotating the tester drum 100, it is preferable to use a servo motor that can be controlled by a computer.

시험되는 타이어(200,300)는 타이어지지대(210,310)에 의해 지지된다. 실제 차량의 하부구조와 같은 구조로 제작하여 도로면의 요철 등의 영향을 감지할 수 하고, 핸들링이 가능하게 하여 코너링 및 브레이킹 등의 영향 등을 제어가 가능하도록 한다.The tires 200 and 300 to be tested are supported by the tire supports 210 and 310. It is manufactured in the same structure as the undercarriage of the actual vehicle, so that it is possible to detect the effects of irregularities on the road surface, and the handling is possible to control the effects of cornering and braking.

도 1과 같이 2개의 타이어(200,300)를 타이어지지대(210,310)에 의해 설치함으로써 실제 차량의 바퀴정렬구조와 같은 상태로 시험할 수 있으며, 또 1개의 타이어만을 지지하여 2륜차의 타이어 시험도 가능하다.As shown in FIG. 1, by installing two tires 200 and 300 by the tire supports 210 and 310, the tires can be tested in the same state as the wheel alignment structure of an actual vehicle. Also, a tire test of a two-wheeled vehicle can be performed by supporting only one tire. .

제어컴퓨터를 이용하여 모터의 속도를 조절함으로써 실제 도로 주행시 발생하는 코너링, 제동, 하중 등 여러가지 상황을 시험할 수 있다.By controlling the speed of the motor using the control computer, various situations such as cornering, braking, and load that occur during actual road driving can be tested.

실외시험을 실내시험으로 대처하여 시험기간 단축 및 안정성 확보할 수 있는도로 시뮬레이션이 가능할 뿐 아니라, 현재 실내시험기들의 단점을 보완하여 여러가지 도로상황을 하나의 시험기로 테스트가 가능하여 시험 비용절감시킬 수 있다.It is possible not only to simulate outdoor roads by indoor tests but also to shorten the test period and to ensure stability, and to compensate for the shortcomings of current indoor testers, and to test various road conditions with one tester, thereby reducing test costs. .
