본 발명은 고무와 같은 탄성중합체의 마찰저항을 측정하는 장치에 관한것으로, 특히 하중변화와 온도, 속도 및 패턴변화에 따른마찰저항을 정확하게 측정할 수 있는 탄성중합체의 마찰저항 측정장치에 관한 것이다.The present invention relates to an apparatus for measuring the frictional resistance of an elastomer such as rubber, and more particularly, to an apparatus for measuring frictional resistance of an elastomer capable of accurately measuring frictional resistance according to load change and temperature, speed, and pattern change.

일반적으로 고무와 같은 탄성중합체(예를들어 차량용 타아어)의 마찰저항을 측정할때, 상기 탄성중합체의 시편을 측정장치의 아스팔트와 같은 노면위에 올려놓고 마찰저항을 측정하도록 되어 있으나, 이러한 종래의 마찰저항 측정장치는 상온에서만 측정이 가능하여 온도변화에 따른 측정이 불가능할 뿐만 아니라 시편에 가해지는 하중이 고정됨에 따라 하중변화에 따른 마찰저항의 측정치를 얻을 수가 없었다.Generally, when measuring the frictional resistance of an elastomer such as rubber (for example, a vehicle tire), the specimen of the elastomer is placed on a road surface such as asphalt of a measuring device, and the frictional resistance is measured. The friction resistance measuring device could not be measured due to temperature change because it could be measured only at room temperature, and the measurement of frictional resistance according to load change could not be obtained as the load applied to the specimen was fixed.

또한 종래의 측정장치는 시편이 고정된 상태를 유지함에 따라 시편의 크기및 패턴변화에 따른 마찰저항의 변화를 측정할 수가 없었으며, 더욱이 노면이 언 빙상노면에서는 이 노면의 온도와 시편의 온도변화에 따른 마찰저항의영향을 정확히 파악할 수 없는 문제점도 있었다.In addition, the conventional measuring device was unable to measure the change in frictional resistance according to the change in size and pattern of the specimen as the specimen remained fixed. Moreover, the temperature of the surface and the temperature of the specimen were changed on the unfrosted road surface. There was also a problem that can not accurately grasp the effect of the frictional resistance.

It is electrically connected.

그리고 본 발명의 측정장치는 주전원 스위치가 온도조절스위치와 브로우 스위치 및 모우터스위치와 병렬연결되고, 상기모우터스위치는 모우터와 로드셀 및 레코더와 병렬연결되어 있다.In the measurement apparatus of the present invention, a main power switch is connected in parallel with a temperature control switch, a brow switch, and a motor switch, and the motor switch is connected in parallel with a motor, a load cell, and a recorder.
