Fig. 1 zeigt eine Schienenanordnung, bei der das strangförmige Profil (12) aus elastomerem Werkstoff, d.h. aus Gummi oder gummiähnlichem Kunststoff, an der Seite des Schienensteges (6) anliegt, die dem Randkranz (2) abgewandt ist, wobei eine Federklemme (25) das hohlkammerfreie Profil an den SchienenSteg preßt. Die Federklemme selbst ist im Bereich der Schienenbefestigungen (8) angeordnet, und zwar unter gleichzeitiger Fixierung durch die jeweilige Schienenbefestigung.Fig. 1 shows a rail arrangement in which the strand-shaped Profile (12) made of elastomeric material, i.e. made of rubber or rubber-like plastic, on the side of the rail web (6) is applied, which faces away from the rim (2), one Spring clamp (25) the hollow chamber-free profile on the rail web presses. The spring clip itself is in the range of Rail fastenings (8) arranged, with simultaneous Fixation by the respective rail fastening.
Das Profil (12), das nur etwa zur Hälfte die Schienenfußoberseite (7') bedeckt, ist nun mit einer Schallschürze (13) versehen, die nach oben gerichtet ist, und zwar in Form eines einstückigen Gesamtprofilkörpers und unter Bildung einer im Bereich des Schienenkopfes (3) sich befindenden Nut (14), die eine ausreichende Tiefe für den Radkranz aufweist, so daß die Schallschürze beidseitig Verwendung finden kann. 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 gesamte Innenseite (16) der Schallschürze (13) ist mit schallschluckenden Elementen versehen, und zwar in Form von Profilierungen, nämlich von Noppen (18), die einstückig mit dem Gesamprofilkörper ausgebildet sind. Außerdem besitzt die Innenschicht (16) der Schallschürze eine Profilnase (21), die am Schienenkopfunterteil (5) anliegt. Die Außenseite (17) der Schallschürze (13) geht stufenförmig in die Profilspitze (15) über.The entire inside (16) of the acoustic apron (13) is with sound-absorbing elements, in the form of Profilings, namely of knobs (18), which are in one piece are formed with the overall profile body. Also owns the inner layer (16) of the acoustic apron has a profiled nose (21), which rests on the lower part of the rail head (5). The outside (17) the acoustic apron (13) goes step-by-step into the profile tip (15) over.
Fig. 2 zeigt eine Schienenanordnung, bei der das einseitig angeordnete und hohlkammerfreie Profil (12') die Schienenfußoberseite (7') vollständig bedeckt. Die Federklemme (25'), die das Profil (12') an den Schienensteg (6) preßt, ist zwischen den einzelnen Schienenbefestigungen (hier nicht dargestellt) angeordnet und umläuft dabei den Schienenfuß (7).Fig. 2 shows a rail arrangement in which the one-sided arranged and hollow chamber-free profile (12 ') the top of the rail foot (7 ') completely covered. The spring clip (25 '), which presses the profile (12 ') onto the rail web (6) between the individual rail fastenings (not here shown) arranged and rotates the rail foot (7).
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
