Description

복륜 타이어 시험설비{Test Equipment of The Twin Tire}Test Equipment of The Twin Tire

본 발명은 트럭 또는 버스용의 타이어와 같이 한 축에 2개의 타이어를 취부하는 복륜 타이어의 실제 주행상태를 관찰하여, 상기 타이어의 내구력 성능을 시험하는 장치에 관한 것으로서, 상세히는 평면 상에서 "ㄷ" 모양으로 된 하중 프레임의 양쪽에 2개의 타이어를 취부하여 로드 휠에 접촉시키고, 이 하중 프레임에 하중을 측정하는 장치인 하이드로 액츄에이터(hydro actuator)를 연결한 것을 특징으로 한다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for testing the durability performance of a tire by observing an actual driving state of a two-wheeled tire that mounts two tires on one axis, such as a tire for a truck or a bus, in detail "c" on a plane. Two tires are mounted on both sides of the load frame in contact with each other to contact the load wheel, and a hydro actuator, which is a device for measuring the load, is connected to the load frame.

현재의 타이어의 내구력 성능을 평가하는 기계는 오로지 한 개의 타이어만 로드 휠에 장착하여 타이어의 내구력 성능을 시험하고 있고, 트럭이나 버스에 실제로 장착되어 주행하는 트윈 타이어 즉, 한 축에 2개의 타이어를 취부한 복륜 타이어의 경우, 실제 필드에서 사용하는 조건으로 시험하기는 힘들어서, 내구력 시험을 종래와 같이 한 개의 타이어만 가지고 실시하기 때문에 2개의 타이어의 상호 작용을 제대로 알 수가 없다.The machine that evaluates the durability performance of the current tire is testing the tire durability performance by mounting only one tire on the road wheel, and using two tires on one axle, that is, a twin tire actually mounted on a truck or bus. In the case of the mounted double-wheeled tires, it is difficult to test the conditions used in the actual field, and since the durability test is performed with only one tire as in the prior art, the interaction between the two tires cannot be known properly.

따라서, 복륜 타이어를 취부한 때를 모사할 수 있는 상태를 시험기에 의해 시험하기 위해서는 복륜 타이어가 실제로 주행하는 상태를 관찰하여 타이어의 내구력을 시험해야 할 필요성이 있게 된다.Therefore, in order to test the state which can simulate the time when a double-wheeled tire was mounted by the tester, it is necessary to observe the state which a double-wheeled tire actually runs, and to test the durability of a tire.

본 발명은 상기한 바와 같이 한 개의 타이어만 취부하여 시험하는 종래 타이어 내구력 시험설비의 문제점을 개선하기 위해 안출된 것으로서, 로드 휠 상에서 이 로드 휠에 의해 주행하는 두개의 타이어를 하중 프레임에 동시에 취부하되, 상기 하중 프레임에 하중을 가하는 장치를 연결하여 복륜 타이어를 취부한 때의 상태를 묘사하여 시험할 수 있는 시험설비를 제공함에 그 목적이 있다.The present invention has been made in order to improve the problems of the conventional tire durability test equipment for mounting and testing only one tire as described above, the two tires running by the road wheel on the road wheel at the same time to the load frame It is an object of the present invention to provide a test facility capable of describing and testing a state in which a double-wheel tire is mounted by connecting a device for applying a load to the load frame.

상기한 바와 같은 목적을 달성하기 위해, 본 발명은 2개의 타이어가 함께 회전하는 회전축을 따라 각각 간격을 두고 설치된 축 하중부와;다리부가 상기 축 하중부에 각각 설치된 "ㄷ" 모양의 하중 프레임과;상기 하중 프레임의 연결부 중앙에서 상기 회전축과 수직인 방향으로 힘을 가하는 액츄에이터와;타이어의 외주면과 맞닿게 하여 회전시키는 로드 휠과;상기 하중 프레임의 양 다리부 사이에 설치된 칸막이를 포함하여 구성되는 것을 특징으로 한다.In order to achieve the object as described above, the present invention provides an axial load portion provided at intervals along each of the rotating shafts in which the two tires rotate together; An actuator exerting a force in a direction perpendicular to the rotation axis at the center of the connecting portion of the load frame; a rod wheel that rotates by contacting the outer circumferential surface of the tire; and partitions installed between both legs of the load frame. It is characterized by.

이하, 첨부된 도면을 참조하여 본 발명에 따른 복륜 타이어 시험설비의 구성을 상세히 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail the configuration of the two-wheel tire test facility according to the present invention.

도 1은 본 발명에 따른 시험설비의 사시도, 도 2는 시험설비의 개략적인 측면도이며, 본 발명은 트윈 타이어의 경우처럼 한 축에 2개의 타이어를 취부한 상태로 주행하는 장비로서 도시한 바와 같이,2개의 타이어가 함께 회전하는 회전축을 따라 각각 간격을 두고 설치된 축 하중부(1,1')와; 다리부(3',3')가 상기 축 하중부(1,1')에 각각 설치된 "ㄷ" 모양의 하중 프레임(3)과; 상기 하중 프레임(3)의 연결부(3")의 중앙에서 상기 회전축과 수직인 방향으로 힘을 가하는 액츄에이터(6)와; 타이어(2,2')의 외주면과 맞닿게 하여 회전시키는 로드 휠(5)과; 상기 하중 프레임(3)의 양 다리부(3',3') 사이에 설치된 칸막이(4)를 포함하여 구성되어 있다.1 is a perspective view of a test facility according to the present invention, Figure 2 is a schematic side view of the test facility, the present invention as shown in the case of a twin tire as a device for driving with two tires mounted on one axis An axial load portion (1,1 ') spaced apart from each other along a rotating shaft where the two tires rotate together; A load frame 3 having a "c" shape in which leg portions 3 'and 3' are respectively provided on the axial load portions 1 and 1 '; An actuator 6 which exerts a force in a direction perpendicular to the rotation axis at the center of the connecting portion 3 "of the load frame 3; and a rod wheel 5 which rotates in contact with the outer circumferential surface of the tires 2, 2 '. And the partition 4 provided between the both legs 3 'and 3' of the load frame 3.

여기서, 상기한 바와 같이 한 쪽의 타이어(2)가 펑크 났을 때, 다른 쪽 타이어(2')에 영향이 미치지 않도록 하는 상기 칸막이(4)는 하중 프레임에서 림 어댑터(rim adapter)까지 1.5m의 길이와 2m 폭의 철판으로 설치한다.Here, when the one tire 2 is flat as described above, the partition 4 which does not affect the other tire 2 'is 1.5 m from the load frame to the rim adapter. It is installed with iron plate of length and 2m width

이상과 같이 구성된 본 발명의 작용관계를 상세히 설명하면 다음과 같다.Referring to the working relationship of the present invention configured as described above in detail.

하중을 가해주는 장치 즉, 상기 하이드로 액츄에이터(6)에서 100N의 힘을 가했을 때 "ㄷ"모양의 하중 프레임(3)이 힘을 두 개로 나누어 가지므로 50:50으로 2축이 힘을 나누어 가진다.When the 100N force is applied to the device that applies the load, that is, the hydro actuator 6, the "c" shaped load frame 3 divides the force into two, so the two axes divide the force by 50:50.

따라서, 상기 하중 프레임과 연결된 타이어(2,2')는 50:50으로 힘을 나누어 가지며, 필드에서 주행하는 것과 똑같이 힘을 나누어 갖게 되고, 주행 중 한 쪽의 타이어(2)가 펑크나면 다른 쪽 타이어에 영향을 미치지 않도록 설치된 칸막이(4)에 의해, 다른 쪽 타이어(2')가 100N 이라는 힘을 그대로 받으므로 실제에서 사용하는 조건을 그대로 시험할 수 있으며, 주행 중 사고가 어떻게 이어지는지 관찰할 수 있게 된다.Thus, the tires 2,2 'connected to the load frame divide the force by 50:50, and share the force as if traveling in the field, and if one tire 2 is flat during driving, the other By the partition 4 installed so as not to affect the tire, the other tire 2 'receives the force of 100N as it is, so the conditions used in the real world can be tested as it is, and the accident can be observed while driving. It becomes possible.

이상과 같은 목적과 구성으로 이루어진 본 발명의 복륜 타이어 시험설비에 의하면, 트럭 또는 버스용의 트윈 타이어의 경우와 같이 두 개의 타이어를 동시에 시험할 수 있으며, 이렇게 동시에 두 본의 타이어를 시험함으로써 복륜 타이어 시험설비의 시험 생산성을 높일 수 있다.According to the double-wheeled tire test facility of the present invention having the above object and configuration, it is possible to test two tires at the same time as in the case of a twin tire for a truck or a bus. Increase the test productivity of the test facility.
