The present invention relates to a pneumatic tire having a concave groove type sound absorbing member. According to the present invention, the pneumatic tire comprises a tread in contact with the road surface, and a sound-absorbing member installed on an inner surface of the tread to reduce vibration noise generated in a cavity between the tread and a rim. The sound-absorbing member is provided with a concave groove formed in a sound-absorbing body of which the thickness of the center and the outermost shell is different from each other in order to disperse and absorb vibration and noise so that the vibration and noise disappear. The vibration and noise generated by friction with the road surface are transmitted to the inside of the tire through the tread, and then are dispersed and sound-absorbed through the concave groove of the sound-absorbing member, so that the vibration and noise can be quickly attenuated.
본 발명은 오목홈형 흡음부재를 구비한 공기입 타이어에 관한 것으로, 노면과 접촉하는 트레드와, 상기 트레드와 림 사이의 공동부에서 발생하는 진동 소음을 감소시키기 위하여 트레드의 내부면에 설치되는 흡음부재를 구비하여 이루어지는 공기입 타이어에 있어서, 상기 흡음부재는, 진동 및 소음을 분산시키고 흡음하여 소멸되도록 하기 위하여 중심과 최외각의 두께를 서로 달리한 흡음체에 오목홈이 형성된 것으로, 노면과의 마찰로 발생한 진동 및 소음이 트레드를 통해 타이어 내부로 전달된 후 흡음부재의 오목홈을 통해 분산되고 흡음되도록 함으로써, 진동 및 소음이 신속하게 감쇄될 수 있도록 한 효과가 있다.
