    • The present invention provides a pneumatic tyre provided with a noise damper in the tyre cavity, which can maintain high-speed durability and producibility while also reducing cavity resonance. The present invention provides a pneumatic tyre comprising a tread having a width TW in contact with the ground during travel, in which a noise damper made of a sound-absorbing material is attached to the tyre internal surface in order to reduce cavity resonance, wherein the noise damper is at least one continuous ribbon made of a sound-absorbing material and having a width W and a thickness E, which is fixed over an attachment width Wc to the tyre internal surface over a range of at least 30% of the inside of the tread in the radial direction, the start end and terminal end which are the two ends of the continuous ribbon are disposed in such a way as to be offset from each other in the axial direction, and the continuous ribbon forms, together with the tyre internal surface, a continuous groove having a groove width D which is at least equal to 10% of the width W of the continuous ribbon.
    • 本发明提供了一种充气轮胎,其在轮胎腔中设置有消声器,该消声器能够保持高速耐久性和生产性,同时还减少了腔谐振。 本发明提供了一种充气轮胎,其包括在行驶期间具有与地面接触的宽度TW的胎面,其中由吸音材料制成的消音器附接到轮胎内表面以便减少空腔共振,其中, 噪声减震器是由吸音材料制成的至少一个连续带,其具有宽度W和厚度E,该宽度W和厚度E在相对于轮胎内表面的附接宽度Wc上在至少30%的内侧范围内固定 在径向上的胎面,作为连续带的两端的起始端和终止端被布置成在轴向方向上彼此偏移,并且连续带与轮胎一起形成 内表面,具有至少等于连续带的宽度W的10%的沟槽宽度D的连续沟槽。
