The present invention is a cross-sectional view and a plan view, the present invention is a temperature control unit for supplying power to the power supply to heat up to the set temperature with reference to the current temperature when the operator sets the heating temperature, and transfers the power supplied from the temperature control unit to the hot plate and heating It consists of a power supply unit for transmitting the temperature change of the negative portion back to the temperature control unit, and a heating unit for heating the heat plate (1) received from the power supply unit to raise the temperature of the rim (R) to a set temperature.

여기서, 상기 온도제어부는 온/오프(ON, OFF)를 실행하는 스위치(12)와, 가열되기 전의 타이어 림(R)의 온도를 출력하는 현재온도표시기(9)와, 작업자가 설정한 림(R)의 온도를 조정하는 온도설정기(11)와, 상기 스위치가 온(ON)되었을 때 켜지고 오프(OFF)되었을 때 꺼지는 램프(10) 및 열판(1)에 전류를 공급하는 SCR유니트(도시되지않음)로 이루어진다.Here, the temperature control unit is a switch 12 for performing the ON / OFF (ON, OFF), the current temperature indicator 9 for outputting the temperature of the tire rim (R) before heating, and the rim set by the operator ( A temperature setter 11 for adjusting the temperature of R) and an SCR unit for supplying current to the lamp 10 and the hot plate 1 which are turned on when the switch is turned on and turned off when turned off. Is not made).

또, 상기 전원공급부는 전원공급용 슬립링(14)과 온도신호용 슬립링(3)으로 이루어진다.In addition, the power supply unit includes a power supply slip ring 14 and a temperature signal slip ring (3).

한편, 상기 가열부는 열선(1a)이 일정간격으로 갖추어진 열판(1)과, 림(R)의 온도와 비드의 온도를 측정하는 온도계(15)로 이루어짐과 더불어, 타이어 외측 비드부에는 사고감지스위치(13)가 갖추어지되, 이 사고감지스위치(13)는 타이어 비드와 간극이 형성하도록 설치되어 온도변화에 의해 타이어 비드의 융기 내기는 파열이 발생될 때 시험기를 멈추는 기능을 하게 된다.On the other hand, the heating portion is composed of a hot plate (1) having a heating wire (1a) at a predetermined interval, and a thermometer (15) for measuring the temperature of the rim (R) and the temperature of the beads, the accident detection on the tire outer bead portion The switch 13 is provided, but the accident detection switch 13 is installed so as to form a gap with the tire bead so as to stop the test machine when a bulging of the tire bead due to temperature change occurs.

상기와 같이 구성된 본 발명 시험기의 작동을 하기와 같이 순차적으로 설명하면, 먼저 시험할 타이어(T)를 타이어 고정축(8)에 끼우고, 이 고정축(8)의 반대편으로 스핀들홀(Rc) 내에 설치된 회전기(도시되지 않음)를 원하는 속도로 작동시킨 후, 스위치(12)를 작동하고 나서 온도설정기(11)로 원하는 림(R)의 온도를 맞추면, 이 온도설정기(11)가 열판(1)을 가열하여 림(R)의 온도를 상승하게 된다.When the operation of the tester of the present invention configured as described above is described sequentially as follows, the tire T to be tested is first inserted into the tire fixing shaft 8, and the spindle hole Rc is opposite to the fixing shaft 8. After operating the rotor (not shown) installed in the inside at a desired speed, operating the switch 12, and then adjusting the temperature of the desired rim R with the temperature setter 11, the temperature setter 11 is heated. (1) is heated to raise the temperature of the rim (R).

이때, 상기 타이어 고정축(8)과 중심축(2)이 타이어와 함께 회전을 하게되고, 슬림링(3)과 이 슬림링(3)을 지지하는 지지대(S)는 회전하지 않게 된다.At this time, the tire fixing shaft 8 and the central shaft 2 is rotated together with the tire, and the slim ring 3 and the support S supporting the slim ring 3 do not rotate.

따라서, 상기 림(R)의 온도가 상승하여 타이어 비드의 온도가 상승하게 되고, 비드가 견딜 수 없는 선을 넘어 비드에 변형이 발생되면, 타이어 비드와 사고감지스위치(13) 간의 간극이 없어짐에 따라, 이를 사고감지스위치(13)가 감지하여 일정한 신호를 보내어 시험기의 작동을 멈추게 한다.Therefore, if the temperature of the rim (R) rises and the temperature of the tire bead rises, and if the bead is deformed beyond the unbearable line, there is no gap between the tire bead and the accident detection switch (13). Accordingly, the accident detection switch 13 detects this and sends a constant signal to stop the operation of the tester.

이상에서 설명한 본 발명에 의하면, 타이어 림(R)에 열판(1)이 설치되며, 타이어의 외측 비드부에는 사고감지스위치(13)가 설치되고, 시험기 축에 타이어 회전기를 장치하여 타이어가 필드에서 작동되는 동일한 조건으로 타이어 비드 내구성을 테스트할 수 있으므로, 타이어 비드 내구성능을 정확하게 측정할 수 있어, 이에 맞는 비드를 타이어에 적용하여 차량의 안전사고를 미연에 방지할 수 있는 효과가 있다.According to the present invention described above, the hot plate (1) is provided on the tire rim (R), the accident detection switch (13) is installed on the outer bead portion of the tire, and the tire is mounted on the field by installing a tire rotator on the tester shaft. Since it is possible to test the tire bead durability under the same operating conditions, it is possible to accurately measure the tire bead durability performance, there is an effect that can prevent the safety accident of the vehicle in advance by applying the bead to the tire.
