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>

Die Profilspitze (15) ragt über die Schienenkopfoberseite (4) hinaus, ohne das Rad (1) zu berühren. Die Mindesthöhe X der Profilspitze, die im wesentlichen senkrecht nach oben verläuft, beträgt zweckmäßigerweise mindestens 30 mm, und zwar bezogen auf die Schienenkopfoberseite (4).The profile (12), which is only about half the top of the rail foot (7 ') is now covered with an acoustic apron (13) provided, which is directed upwards, in the form of a one-piece overall profile body and to form a groove (14) located in the area of the rail head (3), which has a sufficient depth for the wheel rim, so that the acoustic apron can be used on both sides. The profile tip (15) protrudes over the top of the rail head (4) out without touching the wheel (1). The minimum height X the profile tip, which is essentially perpendicular upwards runs, is expediently at least 30 mm, in relation to the top of the rail head (4).

Die Schallschürze (13') unter Bildung der Nut (14') weist auf ihrer Innenseite (16') innerhalb der Profilspitze (15') eine Aussparung (19) auf, in der sich eine schallschluckende Materialschicht (20) mit großer Oberfläche befindet, nämlich in Form eines Filzwerkstoffes (z.B. Mineralfilz oder eines geschäumten Werkstoffes. Die Außenseite (17') geht gewinkelt in die Profilspitze (15') über.The acoustic apron (13 ') has the groove (14') on its inside (16 ') within the profile tip (15') a recess (19) in which a sound absorbing Material layer (20) with a large surface, namely in the form of a felt material (e.g. mineral felt or a foamed material. The outside (17 ') is angled into the profile tip (15') about.

Fig. 3 zeigt nun eine Schienenanordnung, bei der das Profil (12'') beidseitig am Schienensteg (6) anliegt. Das mit Hohlkammern (22, 23, 24) versehene Profil (12'') bedeckt die Schienenfußoberseite (7') vollständig. Die Außenseite des Profils und die Außenseite (17'') der Schallschürze (13'') verlaufen im wesentlichen fluchtend.Fig. 3 now shows a rail arrangement in which the profile (12 '') rests on both sides of the rail web (6). The one with hollow chambers (22, 23, 24) provided profile (12 '') covers the Rail foot top (7 ') completely. The outside of the Profiles and the outside (17 '') of the acoustic apron (13 '') are essentially in alignment.

Die Federklemme (25'') ist zwischen den einzelnen Schienenbefestigungen (hier nicht dargestellt) angeordnet und umläuft dabei den Schienenfuß (7). Die Federklemme weist dabei eine Haltenase (26) auf, die sich in einer entsprechenden Aussparung (27) des Profiles (12'') befindet.The spring clip (25 '') is between the individual rail fastenings (not shown here) arranged and runs around the rail foot (7). The spring clip points a retaining lug (26), which is in a corresponding Recess (27) of the profile (12 '').

Die Schallschürze (13'') unter Bildung der Nut (14'') für die Aufnahme des Radkranzes (2) ist auf ihrer Innenseite (16'') innerhalb der Profilspitze (15'') mit einer Profilierung versehen, und zwar in Form von Rillen (28).The acoustic apron (13 '') forming the groove (14 '') for receiving the wheel rim (2) is on the inside (16 '') within the profile tip (15 '') with a profile provided, in the form of grooves (28).

Der Gesamtprofilkörper besteht bei den Ausführungsbeispielen gemäß Fig. 1 bis 3 aus einem witterungsbeständigen Werkstoff, insbesondere auf Basis von EPDM. Der hochdämpfende Gesamtprofilkörper besitzt dabei einen Verlustwinkel von mindestens 5°.The overall profile body is in the embodiments 1 to 3 made of a weather-resistant material, especially based on EPDM. The highly damping overall profile body has a loss angle of at least 5 °.
