Abstract

In track systems for rail vehicles, air-borne noise is reduced by an arrangement of packing (6) of loose material in a suitable casing (8) positioned between and/or at the sides of the rails (5) and on and/or in front of the free surfaces and side faces of the supporting structure (3,4) outside the vehicle profile (7). Pref. the casing comprises a mesh container or basket of rigid dimensions, with mesh apertures small enough to prevent material escaping. It pref. consists of corrosion-resistant plastic, e.g. of polyethylene, polypropylene, polyamide, polycarbonate, polyester, polyacrylic or mixtures of these, or of glass fibres or plastic-coated glass fibres. Also claimed is a method for preparing and placing of the packed material. Effective noise redn. by method capable of automation.

Description

Die Erfindung betrifft eine Vorrichtung zur Verminderung von Luftschall bei Schienenverkehrswegen, vornehmlich bei Festen Fahrbahnen für schienengebundenen Verkehr, wie sie gattungsmäßig im Oberbegriff des Anspruchs 1 beschrieben sind.The invention relates to a device for reducing airborne noise Rail traffic routes, primarily on slab tracks for rail-bound traffic, as described generically in the preamble of claim 1.

Aus der unveröffentlichten DE 195 17 384.8 sind Vorrichtungen zur Verminderung von Luftschall der eingangs genannten Gattung bekannt. Ergänzende Maßnahmen zur Verminderung von Luftschall sind aus den ebenfalls unveröffentlichten Patentschriften DE 195 29 754.7 und DE 195 17 384.8 bekannt. Weder aus den vorgenannten Veröffentlichungen noch aus dem dem Erfinder sonst zugänglichen Stand der Technik sind Maßnahmen entnehmbar, die der Minderung der Schallemission dienen sollten, die durch Relativbewegung zwischen den Schienenklemmen und dem Schienenfuß entsteht, wenn sich die Schiene beim Überfahren des Stützpunktes auf der Schwelle durch ein Schienenfährzeug verformt.From the unpublished DE 195 17 384.8 devices for reducing Airborne sound of the type mentioned at the beginning. Additional measures for Airborne noise is reduced from the likewise unpublished patent documents DE 195 29 754.7 and DE 195 17 384.8. Neither from the aforementioned publications Measures are still from the prior art otherwise accessible to the inventor removable, which should serve to reduce the sound emission, by relative movement between the rail clamps and the rail base occurs when the rail is in the A rail vehicle deforms the passage over the base on the threshold.

Der Erfindung liegt die Aufgabe zugrunde, die Schallemission an dieser Lärmquelle zu mindern.The invention is based, to reduce the noise emission at this noise source the task.

Die Aufgabe wird durch eine auf die den Schienenfuß niederhaltenden Enden der Schienenklemme aufgebrachte, aus einem die Schallemission dämmenden Werkstoff - z. B. Kunststoff - hergestellte Ummantelung gelöst, wie sie im kennzeichnenden Teil des Anspruchs 1 beschrieben sind. Ausbildungsformen der Ummantelung sind in den Ansprüchen 2 u. 3 angegeben.The task is carried out by one on the ends of the rail holding down the Rail clamp applied, from a sound-absorbing material - z. B. Plastic-made casing solved, as in the characterizing part of the claim 1 are described. Forms of training of the casing are in claims 2 u. 3rd specified.

Die erfindungsgemäße Vorrichtung wird durch Beispiele in den Fig. 1 u. 2 erläutert. Es zeigen:The device according to the invention is illustrated by examples in FIGS . 2 explained. Show it:

Fig. 1 einen Schnitt senkrecht zur Gleisachse durch eine erfindungsgemäße Schienen­ befestigung, Fig. 1/1 mit manschettenförmiger, Fig. 1/2 mit hülsenförmiger Um­ mantelung der Schienenklemmenenden. Fig. 1 shows a section perpendicular to the track axis through a rail attachment according to the invention, Fig. 1/1 with cuff-shaped, Fig. 1/2 with sleeve-shaped To sheath the rail terminal ends.

Fig. 2 eine Aufsicht auf eine Schienenklemme mit einer die Schallemission mindernden Ummantelung der Klemmenenden, Fig. 2/1 mit manschettenförmiger, Fig. 2/2 mit hülsenförmiger Ummantelung. Fig. 2 is a plan view of a rail clip having an acoustic emission-reducing coating of the clamping member, FIG. 2/1 with sleeve-shaped, FIG. 2/2 with sleeve-shaped casing.

Auf der Schwelle 1 ist die Schiene 2 mit herkömmlichen bekannten Mitteln befestigt. Zu den Befestigungsmitteln gehören Schienenklemmen 4, die einerseits mit Befestigungsschrauben 8 in der Schwelle 1 verankert sind, andererseits mit ihren Enden 5 den Schienenfuß 3 auf der Schwelle elastisch halten. Die Enden 5 der Schienenklemmen 4 sind mit Ummantelungen 6, 7 aus geeignetem Werkstoff - z. B. Kunststoff - versehen. Die Ummantelungen sollen Geräuschemissionen vermindern, die bei einer Relativbewegung zwischen Schienenfuß 3 und Schienenklemme 4 entstehen, in dem diese beiden Teile aufeinander reiben. Diese Relativbewegung wird durch die Schienenverformung beim Überfahren des Gleises mit einem Schienenfährzeug verursacht. Die Ummantelung kann die Form einer Manschette 6 oder einer Hülse 7 aufweisen.On the threshold 1 , the rail 2 is fixed by conventional means. The fastening means include rail clamps 4 , which are anchored on the one hand with fastening screws 8 in the sleeper 1 , and on the other hand with their ends 5 hold the rail foot 3 elastically on the sleeper. The ends 5 of the rail clamps 4 are with sheaths 6, 7 made of a suitable material - z. B. plastic - provided. The sheaths are intended to reduce noise emissions which arise during a relative movement between the rail foot 3 and the rail clamp 4 , in which these two parts rub against one another. This relative movement is caused by the rail deformation when a rail vehicle drives over the track. The casing can have the shape of a sleeve 6 or a sleeve 7 .
