Noise absorption device for rail vehicle wheel and associated rail vehicle wheel

The invention relates to a noise absorption device for a rail vehicle wheel and an associated rail vehicle wheel. The noise-absorbing device (1) for a railway vehicle wheel includes: at least one strip (13A, 13B) extending radially from a connecting end (15A, 15B) capable of being fastened to the periphery of the wheel, to a free end (17A, 17B); and at least one damping mass (19A, 19B, 19C) fastened on a face of the free end (17A, 17B) of the strip, away from the connecting end (15A, 15B). The strip (13A, 13B) includes at least two metal or composite layers and at least one layer of viscoelastic material gripped between the two or composite metal layers. 本发明涉及用于铁路车辆车轮及相关铁路车辆车轮的噪声吸收装置，其中用于铁路车辆车轮的噪声吸收装置(1)包括：至少个条带(13A，13B)，所述条带从能够固定到车轮(3)的外围的连接端(15A，15B)径向延伸到自由端(17A，17B)；至少个阻尼块(19A，19B，19C)，所述阻尼块固定在条带的自由端(17A，17B)的表面上，远离连接端(15A，15B)。条带(13A，13B)包括至少两个金属或复合层以及夹在所述两个或复合金属层之间的至少个粘弹性材料层。
