Description

타이어의 접촉노면 충격시험설비{Rood impact test equipment of tire}Road impact test equipment of tire

본 발명은 실내에서 타이어의 노면충격(Impact bulge)을 평가할 수 있는 타이어의 접촉노면 충격시험설비에 관한 것이다.The present invention relates to a contact surface impact test facility of a tire capable of evaluating the impact bulge of a tire indoors.

일반적으로 타이어에 대한 객관적 결과를 도출하기 위해 실내에서 각종 안전도 시험을 수행하는바, 일례로 타이어의 접지면에 대한 충격시험장치는 다양한 충격물이 형성된 회전드럼 위에서 타이어를 접촉시켜 타이어의 안전도를 평가하도록 되어 있으나, 이는 타이어가 접지하는 실제 노면조건과 다른 접지형상으로 회전드럼에 접촉하는 상태이기에 평가의 부정확성이 있다.In general, various safety tests are performed indoors in order to derive an objective result for a tire. For example, an impact test apparatus against a ground plane of a tire contacts a tire on a rotating drum on which various impacts are formed to improve the safety of the tire. Although it is supposed to be evaluated, this is inaccurate in the evaluation because the tire is in contact with the rotating drum in a shape different from the actual road condition to which the tire is grounded.

즉, 타이어가 회전드럼에 접지하는 경우에 실제 노면접지보다 접지 길이가 큰 폭으로 작아지는 특성이 있기 때문이다.In other words, when the tire is grounded to the rotating drum, there is a characteristic that the ground length is significantly smaller than the actual road grounding.

또한, 차량에 장착된 타이어는 브레이크 드럼, 허브 등과 조립하여 이루어진 휠 어셈블리(Wheel assembly)로서 차량과는 충격흡수장치 등을 매개로 연결되어 있으나, 종래 실내 타이어의 노면 충격시험설비에서는 이 같은 충격흡수장치가 없는 상태에서 타이어의 노면충격을 시험 평가함에 따라 평가의 불일치성으로 인해 신뢰도가 떨어지는 단점이 있었다.In addition, the tire mounted on the vehicle is a wheel assembly made by assembling a brake drum, a hub, etc., and the vehicle is connected to a vehicle through a shock absorbing device. As the road impact of the tire was tested in the absence of the device, the reliability of the tire was deteriorated due to the inconsistency of the evaluation.

이에 본 발명은 상기와 같은 종래 문제점을 감안하여 발명된 것으로, 노면충격에 의하여 타이어 파손(Impact bulge)에 대한 내구력을 갖추기 위해 활용되면서 타이어 성능보완 연구에 도움을 주는 타이어의 접촉노면 충격시험장치를 제공함에 그 목적이 있다.Accordingly, the present invention has been invented in view of the conventional problems as described above, and is used to provide durability for tire damage (impact bulge) by road impact, while also providing a tire contact road impact test apparatus that helps to study tire performance. The purpose is to provide.

상기와 같은 목적을 달성하기 위한 본 발명은 타이어가 노면에서 접촉하여 각종 충격물에 의해 충격이 가해져서 타이어의 내구성을 시험 평가할 수 있는 타이어의 접촉노면 충격시험설비에 있어서, 상기 타이어가 장착되는 구동부, 상기 3륜 시험 운동체의 시험 타이어에 충격을 가하는 다양한 충격물이 배치된 충격존(Impact zone) 및, 상기 3륜 시험 운동체를 안전하게 정지시키는 스톱퍼를 구비하여 이루어져 있다.The present invention for achieving the above object is a tire contact road surface impact test facility in which the tire is in contact with the road surface and the impact is applied by various impact materials to evaluate the durability of the tire, the drive unit is mounted tire And an impact zone in which various impact objects that impact the test tires of the three-wheeled test body are disposed, and a stopper for safely stopping the three-wheeled test body.

이와 같은 본 발명에 따른 타이어의 접촉노면 충격시험장치는 충격흡수장치를 갖춘 3륜 시험 운동체에 장착된 타이어가 노면 접촉시 이 노면의 충격에 의해서 야기되는 파손에 대한 내구력을 갖추기 위한 타이어 성능보완 연구에 활용될 수 있는 자료를 얻을 수 있도록 되어 있다.The tire contact road impact test apparatus according to the present invention is a tire performance supplement study for equipping a tire mounted on a three-wheeled test body with a shock absorbing device to provide durability against damage caused by the impact of the road surface when the tire is in contact with the road surface.
