  • the invention relates to a wheel for a rail vehicle, comprising a hub, a tread and a sound absorption device arranged in the region between the hub and the tread, which has at least one sound absorption element.
  • a sound absorber for a wheel of a rail vehicle is described in DE 20 2006 012 852 Ul, which has two parallel absorber plates with an intermediate damping layer.
  • the absorber plates are divided by at least one slot into tongue-like sections, wherein the slot is covered by a slot-free region of the adjacent absorber plate.
  • this known sound absorber has a relatively complicated construction and could not achieve the desired sound absorption. It is therefore an object of the present invention to provide a wheel for a rail vehicle with a sound absorbing device, which has a simple construction and is able to achieve a comparison with known solutions improved sound absorption.
  • the inventive design of the sound absorbing element as a fabric with warp threads and weft threads and at the points of contact of the warp threads with the weft yarns friction points or provided with slots expanded metal sheet results in a much better sound absorption or sound attenuation than in known solutions, so that a very good noise attenuation results by means of the sound absorption element according to the invention.
  • a force or velocity excitation of the wheel produces flexural waves which deform the wheel at least to a certain degree, which, depending on the frequency and amplitude of the vibration, results in a sound radiation through the wheel.
  • the sound absorption element according to the invention together with the friction between the same and the wheel resulting from the attachment of the sound absorption element to the wheel, produces a high damping of this so-called structure-borne sound. Furthermore, an acoustic short circuit results on the surface of the sound absorption element in which the pressure waves excited by the vibrations are compensated within and on the surface of the sound absorption element.
  • Slotted expanded metal sheet has the advantage that due to the friction points formed at the points of contact of the warp wires with the weft wires a friction within the fabric is established, which leads to a co-responsible for the damping loss factor in the tissue.
  • bending and stretching forces occur during bending of the tissue and the vibrations in the tissue are converted into heat by friction.
  • a fabric can be produced very quickly and inexpensively, so that this solution is also very suitable for mass production.
  • very thin wires can be used for a fabric, whereby correspondingly thin and flexible fabrics can be formed. Such a fabric can thus be adapted in a relatively simple manner to the contour of the respective portion of the wheel to be damped.
  • the sound absorption element has a plurality of layers of the fabric of the microperforated sheet or the expanded metal sheet.
  • the sound absorption element is divided over its surface into several segments. Such a division of the sound absorbing element into several segments allows for a simple attachment of the

  • At least one plate-shaped support element is attached to the tread or on a connecting element connecting the hub to the tread, to which the sound absorption element is attached.
  • a support element increases the rigidity of the entire sound absorption device and absorbs the sound energy introduced into the wheel via the rail in order to pass it on to the sound absorption element attached to the support element, where the sound is ultimately absorbed.
  • a simple attachment of the sound absorbing element to the wheel may consist in that these components are screwed by means of a pressing element on the tread or on the connecting element.
  • the support element is received at its end facing the hub in a mounted on the hub retaining ring, this represents an improved support of the support Furthermore, in this way a full-surface coverage of the wheel is created so that the penetration of dirt into a region between the wheel and the sound absorption device is prevented.
