The present invention relates to a test device for grip performance of a tire on a wet road. More specifically, when testing grip performance of a tire on a wet road, a location of a water ejecting nozzle is able to automatically be controlled to be set to a center part of a tire width direction, wherein the water ejecting nozzle automatically ejects water on a road in accordance with an offset of a wheel and a change in width of the tires to be tested. As such, the present invention is able to improve a convenience in operation and efficiency of the grip performance test by reducing time consumption, and is able to automatically control a location of a water ejecting nozzle; thereby being capable of enhancing credibility of the grip performance test.

    본 발명은 타이어의 젖은 노면 제동 성능 시험 장치에 관한 것으로서, 좀더 상세하게는 타이어 젖은 노면 제동 성능 평가 시 시험하고자 하는 타이어들의 휠 오프셋(Wheel offset) 및 폭 변화에 따라 자동으로 노면에 물을 분사하는 물 분사 노즐의 위치를 타이어의 폭 방향 중심부에 맞추도록 자동 조절할 수 있도록 함으로써 작업 편의성을 높이고 소요 시간을 단축시켜 제동 성능 평가 시험의 효율을 향상시킬 수 있도록 함과 아울러 물 분사 노즐의 위치를 자동 조절함으로써 제동 성능 평가의 신뢰성을 향상시킬 수 있는 효과를 갖는다.
