The invention provides a pneumatic tire capable of suppressing broadband noise, which comprises an annular tire cavity jointly formed by the inner side of a tread, the inner side of a tire side part and the inner side of a tire bead part, and the tire side part comprises a first tire side part and a second tire side part which are symmetrically arranged, at least one same-frequency silencing assembly is arranged on the inner side of the first tire side part in the circumferential direction of the annular tire cavity, and at least one different-frequency silencing assembly is arranged on the inner side of the second tire side part in the circumferential direction of the annular tire cavity. According to the invention, the silencing assembly is additionally arranged on the inner surface of the tire at the tire side part to replace a traditional Helmholtz resonator which is additionally arranged on the surface of a rim, so that the structure is greatly simplified, and the manufacturing is convenient; the silencing assembly is an adjustable device, different resonant frequencies are coped with by adjusting the position of a piston, broadband noise reduction is achieved, and the applicability is higher.
本发明提供一种能够抑制宽频噪音的充气轮胎,包括由胎面内侧、胎侧部内侧和胎圈部内侧共同形成的环形轮胎空腔,所述胎侧部包括对称设置的第一胎侧部和第二胎侧部,该第一胎侧部的内侧沿环形轮胎空腔的圆周方向设置有至少一个同频消声总成,该第二胎侧部的内侧沿环形轮胎空腔的圆周方向设置有至少一个异频消声总成。本发明在胎侧部的轮胎内表面加装消声总成,代替传统的在轮辋表面加装亥姆霍兹共振器,其结构大为简化,便于制造;消声总成为可调装置,通过调节活塞位置应对不同的共振频率,实现了宽频降噪,适用性更强。
