A tire sound absorption part is arranged in a tire, the tire sound absorption part is made of a porous material and provided with a first side and a second side, the first side faces the inner circumferential surface of the tire, and the second side is back to the inner circumferential surface of the tire; the first side is provided with two convex ribs and a groove, the two convex ribs are used for being connected with the inner circumferential surface of the tire, and the groove is located between the two convex ribs; and viewed from the cross section of the tire sound absorption part , the opening of the groove has an opening width, the tire sound absorption part has a maximum width, and the ratio of the opening width to the maximum width is between 20% and 60%. Through the design of the sound absorption piece, vibration of gas in the cavity of the tire can be absorbed, so that noise transmitted to the outside from the tire is reduced.
一种轮胎吸音件,供设置于一轮胎的内部,该轮胎吸音件由多孔隙材料制成,其具有一第一侧与一第二侧,该第一侧朝向该轮胎的内周面,该第二侧背对该轮胎的内周面;该第一侧具有两个凸肋以及一凹槽,该两个凸肋供与该轮胎的内周面相连接,该凹槽位于该两个凸肋之间;其中,由该轮胎吸音件的断面观之,该凹槽的开口具有一开口宽度,该轮胎吸音件具有一最大宽度,该开口宽度与该最大宽度的比值介于20%至60%之间。通过上述吸音件的设计,可吸收在轮胎空腔中之气体的振动,以降低自轮胎传递至外部的噪音。
