Abstract

A rail for a permanent way laid on a concrete bed, without ballast, and partic. for urban train and tramways, has an acoustic shrouding (13) fitted to the rail profile (12). The shroud is a one-piece unit profiled body, angled upwards. It forms a groove (14) at the rail head zone (4) with a depth sufficient to accommodate the wheel flange (2), and extends to a point (15) above the head (4) of the rail, without touching the wheels (1) of the rolling stock. The whole profile body is of a weather-resistant material e.g. based on EPDM, and the interior of the pointed end can be cladded with a layer e.g. a mineral felting or a foamed plastic. <IMAGE>

Description

Die Erfindung betrifft eine Schienenanordnung, bestehend aus einer Schiene, die auf einer festen Fahrbahn aus Beton (schotterloser Gleisoberbau) angeordnet ist, insbesondere in Verbindung mit einer Rippenplatte und einer elastischen Schienenunterlage; beidseitig in Abstand angeordneten Schienenbefestigungen; einem strangförmigen Profil aus elastomerem Werkstoff, das ein- oder beidseitig am Schienensteg anliegt; sowie einer Federklemme aus Metall, die das Profil an den Schienensteg preßt (DE-A-31 47 387, EP-A-0 150 264).The invention relates to a rail arrangement consisting of a rail, which is arranged on a solid carriageway made of concrete (ballast-free track superstructure), in particular in connection with a ribbed plate and an elastic rail support; rail fastenings spaced on both sides; a strand-shaped profile made of elastomeric material, which rests on one or both sides of the rail web; and a spring clip made of metal that presses the profile onto the rail web (DE-A-31 47 387, EP-A-0 150 264).

Die Luftschallabstrahlung von Bahnen (Stadt-, Straßen- und Trambahn), erzeugt durch das Rad-Schiene-System und durch unter der Bahn angeordneten Aggregaten, ist erheblich, wobei beim schotterlosen Gleisoberbau sich der Luftschallpegel um etwa 3 bis 5 dB erhöht.The airborne sound emission from trains (city, street and tram), generated by the wheel-rail system and by units arranged under the train, is considerable, whereby the airborne sound level increases by about 3 to 5 dB in the ballast-free track superstructure.

Die Aufgabe der Erfindung besteht nun darin, die Schallabstrahlung, insbesondere unter dem Gesichtspunkt der Kompensation des oben erwähnten Wertes, zu verringern.The object of the invention is now to reduce the sound radiation, in particular from the point of view of compensating for the value mentioned above.

Gelöst wird diese Aufgabe gemäß Kennzeichen des Anspruchs 1 durch eine Schienenanordnung, bei der das Profil mit einer Schallschürze versehen ist, die nach oben gerichtet ist, und zwar in Form eines einstückigen Gesamtprofilkörpers und unter Bildung einer im Bereich des Schienenkopfes sich befindenden Nut mit ausreichender Tiefe für den Radkranz sowie einer Profilspitze, die über die Schienenkopfoberseite hinausragt, ohne das Rad zu berühren.This object is achieved according to the characterizing part of claim 1 by a rail arrangement in which the profile is provided with a sound apron which is directed upwards, namely in the form of a one-piece overall profile body and with the formation of a groove in the region of the rail head with sufficient depth for the wheel rim and a profile tip that projects beyond the top of the rail head without touching the wheel.

Zweckmäßige Ausgestaltungen der Erfindung sind in den Unteransprüchen 2 bis 23 genannt.Expedient embodiments of the invention are mentioned in subclaims 2 to 23.
