Abstract (en)
[origin: EP0542712A1] Acoustic protection cover for a wheel of a rail vehicle. In order to damp sound vibrations, produced during rolling movement, between rail and wheel as well as possible, the acoustic protection is constructed as a hood 1 so that the best possible enclosure (covering) of the wheel disc is achieved thereby. The hood 1 can extend as far as the lower boundary profile according to the UIC standard, if necessary including a permitted degree of wear of the diameter of the wheel disc, and the hood 1 is rotatably mounted concentrically with respect to the wheel 2 on the inside of the wheel on the shaft 6 of the wheel set by means of a support bearing 5 and, on the outside of the wheel, is either also rotatably mounted on the shaft 6 of the wheel set by means of a further support bearing 5' or rigidly attached to the bearing housing 3 of the wheel set. The hood 1 can also be merely rigidly attached to the bearing housing 3 of the wheel set or borne by the bearing housing 3 of the wheel set. <IMAGE>
