Opfindelsen angår et støjdæmpningslegeme til et køre-hjul, især et skinnehjul, med i omkredsretningen ved siden af hinanden anbragte bølgeledere i form af horndele, idet bølgelederne danner en cirkelringskive og er udformet såle-5 des, at i det mindste den ene side af hver bølgeleder forløber tangentialt til cirkelringskivens inderradius og en del af bølgelederen eventuelt er opdelt i yderligere horndel-formede segmenter.BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a noise suppression body for a driving wheel, in particular a rail wheel, with waveguides arranged in the circumferential direction in the form of horn parts, the waveguides forming a circular ring disc and being formed so that at least one side of each the waveguide extends tangentially to the inner radius of the circular disc and a portion of the waveguide is optionally divided into further horn-shaped segments.
Et sådant støjdæmpningslegeme er omhandlet i beskri-10 velsen til DE-PS 31 19 497 (DK-PS 152901). Støjdæmperens bølgeledere er ved deres grundflader ved hjælp af afstandsstykker forbundet til en fælles basis og er ved hjælp af skruer fast forbundet med hjulkransen.Such a noise suppression body is disclosed in the description of DE-PS 31 19 497 (DK-PS 152901). The muffler waveguides are connected at their base surfaces by means of spacers to a common base and are fixedly fixed to the wheel rim by means of screws.
Ved denne kendte teknik dæmpes ganske vist radiale 15 og aksiale svingninger af hjulet, men forsøg har vist, at skrueforbindelserne ved hjulkransen ikke er tilstrækkelige til at tilvejebringe en optimal dæmpning af svingningerne i hjulets akseretning.In this prior art, although radial 15 and axial oscillations of the wheel are attenuated, experiments have shown that the screw connections at the wheel rim are not sufficient to provide an optimal damping of the oscillations in the axis of the wheel.
Det er derfor formålet med opfindelsen at anvise et 20 støjdæmpningslegeme, hvormed det er muligt at opnå en roere effektiv dæmpning af svingningerne i kørehjulets akseretning, og dette er ifølge opfindelsen opnået ved, at bølgelederne til dæmpning af kørehjulets aksiale svingninger ved deres grundflader er bøjet udad parallelt med kørehjulets akseret-25 ning og er fast forbundne med kørehjulets hjulkrans ved de afbøjede grundflader.It is therefore an object of the invention to provide a noise suppression body with which it is possible to obtain a rudder effective attenuation of the oscillations in the axial direction of the driving wheel, and this is achieved according to the invention in that the waveguides for damping the axial oscillations of the driving wheel are bent outwards parallel to the axis of the drive wheel and are firmly connected to the rim of the drive wheel at the deflected ground surfaces.
Omfattende forsøg har vist, at alene den således på overraskende simpel måde tilvejebragte faste forbindelse mellem bølgeledernes afbøjede grundflader og hjulkransen 30 medfører den tilstræbte optimale dæmpning af svingningerne i hjulets akseretning.Extensive experiments have shown that only the thus-surprisingly simple fixed connection between the deflected ground surfaces of the waveguides and the wheel rim 30 results in the desired optimal damping of the oscillations in the axis direction of the wheel.
En fordelagtig udførelsesform for støjdæmpningslegemet ifølge opfindelsen beskrives i det følgende under henvisning til tegningen, hvor 35 fig. 1 viser en del af et støjdæmpningslegeme med tangentialt forløbende horndele anbragt på et kørehjul, og 2An advantageous embodiment of the noise suppression body according to the invention is described below with reference to the drawing, in which FIG. 1 shows a part of a noise suppression body with tangentially extending horn parts arranged on a drive wheel, and 2

fig. 2 et tværsnit gennem et støjdæmpningslegeme.FIG. 2 is a cross-section through a noise suppression body.
Det i fig. 1 viste støjdæmpningslegeme er sammensat af i omkredsretningen ved siden af hinanden anbragte bølgeledere i form af horndele la til lh. De støjdæmpningslegemer 5 dannende bølgeledere la til lh er fastgjort til et skinnehjuls hjulskrans 2. Hjulakselen 3 er ført gennem støjdamperen inden for bølgeledernes inderradius.The FIG. 1, the noise suppression body shown in the figure is composed of adjacent waveguides arranged in the circumferential direction in the form of horn parts 1a to 1h. The noise attenuating bodies 5 forming waveguides 1a to 1h are attached to the rim of a rail wheel 2. The wheel shaft 3 is passed through the noise damper within the inner radius of the waveguides.
Vedrørende yderligere detaljer henvises til DE-PS 31 19 497.For further details, refer to DE-PS 31 19 497.
10 I det i fig. 2 viste tværsnit gennem støjdæmpnings legemet ses flere oven på hinanden anbragte og hinanden dækkende bølgeledere 4, 5 og 6. Bølgelederne 4, 5, 6 er ved deres grundflader bøjet udad parallelt med skinnehjulets akseretning og er med mellemlag 7 forbundet til en fælles 15 basis og ved hjælp af skruer 8 forbundet med hjulkransen 2 ved de afbøjede grundflader.10 In the embodiment of FIG. 2, the waveguides 4, 5, 6 are bent at their base surfaces outwardly parallel to the axis of the rail wheel and are connected to a common base at intermediate layers 7 and by means of screws 8 connected to the wheel rim 2 at the deflected ground surfaces.
De stabile mellemlag 7 befinder sig mellem de enkelte bølgeledere 4, 5, 6. Eventuelt kan et sådant mellemlag også være anbragt mellem hjulkransen 2 og bølgelederen 6. Mellem-20 lagene i området hvor bølgelederne er fastgjort sikrer overholdelse af en bestemt afstand mellem bølgelederne og eventuelt til hjulkransen.The stable intermediate layers 7 are located between the individual waveguides 4, 5, 6. Optionally, such intermediate layer may also be arranged between the wheel rim 2 and the waveguide 6. The intermediate layers in the region where the waveguides are attached ensure compliance with a certain distance between the waveguides and possibly to the rim.
Mellem bølgelederne 4, 5, 6 er der i det øvrige område, dvs. uden for bølgelederfastspændingen anbragt lag 9 25 af dæmpningsmasse.Between the waveguides 4, 5, 6 there are in the other area, ie. Layer 9 25 of damping mass is placed outside the waveguide clamp.
Hver af bølgelederne la til lh fastgøres til hjulkransen 2 ved hjælp af mindst én skrue. Naturligvis må hver af de på hjulkransen 2 i omkredsretningen anbragte bølgeledere la til lh af statiske grunde have samme antal fast-30 gørelsesskruer 8.Each of the waveguides 1a to 1h is secured to the wheel rim 2 by at least one screw. Of course, each of the waveguides 1a to 1h located on the wheel rim 2 in the circumferential direction must have the same number of fixing screws 8 for static reasons.
