Abstract

The aim of the invention is to reduce the wheel impact during travelling over the expansion joint of rails. This is achieved by, in the expansion joint (3), a wedge (1) with a small wedge angle being inserted horizontally into the adjacent ends of the rail, i.e. into upper longitudinal recesses of the rail heads (2). By use of the rail wedge, firstly the noise as a result of the wheel impact during travelling over the expansion joint is reduced to a minimum, secondly the damage to the wheels and thirdly that of the rail ends is prevented, which results in reduced maintenance costs for the wheels as well as the rail in addition to the greatly reduced noise emission. <IMAGE>

**WARNUNG** Anfang DESC Feld konnte Ende CLMS uberlappen **.

 



   PATENTANSPRÜCHE
1. Fugenverbindung von Schienen zur Verminderung des Radstosses, gekennzeichnet durch einen Keil, der in obere Längsausnehmungen benachbarter Schienenköpfe angeordnet ist.



   2. Verwendung der Fugenverbindung nach Patentanspruch 1 für Eisenbahnschienen.



   Die Erfindung betrifft einen Schienenkeil, der zur Überbrückung der Dilatationsfuge in die beiden, an die Dilatationsfuge angrenzenden, Schienenenden eingeführt wird.



   Die Dilatationsfugen bei Eisenbahnschienen werden heute mehrheitlich durch Schweissung vollständig geschlossen, womit Schienenstücke ohne Dilatationsfugen von beliebiger Länge, bei fachgerechter Schwellenverankerung, eingebaut werden können.



   In Kurven sind Dilatationsfugen in gewissen Abständen, je nach Kurvenradius vorzusehen, da sonst die seitlichen Ablenkkräfte aus Temperaturspannungen zu gross werden.



   Der Erfindung liegt die Aufgabe zugrunde, Dilatationsfugen bei Schienen zu überbrücken.



   Erfindungsmässig wird dies dadurch erreicht, dass bei der Dilatationsfuge ein Keil horizontal in die benachbarten Enden der Schiene, d. h. in obere Längsausnehmungen der Schienenköpfe eingeführt wird.



   Der Schienenkeil besteht vorzugsweise aus Metall, insbesondere aus Stahl einer Güterklasse, die wenigstens derjenigen der Schiene entspricht.

 

   Im folgenden wird anhand der beiliegenden Zeichnungen ein Ausführungsbeispiel näher beschrieben. Es zeigen
Fig. 1 einen Querschnitt,
Fig. 2 einen Längsschnitt,
Fig. 3 eine Ansicht von oben des eingebauten Schienenkeils.



   Der in der Zeichnung dargestellte Schienenkeil 1 mit kleinem Keilwinkel weist an beiden Enden einen Abstand zum Material des Schienenkopfes 2 auf, der etwas grösser als die Hälfte des Schienenabstandes in der Dilatationsfuge 3 ist.



   Durch die Anwendung des Schienenkeils wird erstens der Lärm des Radstosses beim Überfahren der Dilatationsfuge auf ein Minimum abgemindert, zweitens wird die Beschädigung der Räder und drittens diejenige der Schienenenden verhindert, wodurch sich neben der stark reduzierten Lärmemission verminderte Unterhaltskosten der Räder sowie der Schienen ergeben.

   PATENT CLAIMS
1. Joint connection of rails to reduce the wheel joint, characterized by a wedge which is arranged in the upper longitudinal recesses of adjacent rail heads.



   2. Use of the joint connection according to claim 1 for railroad tracks.



   The invention relates to a rail wedge, which is inserted into the two rail ends adjoining the dilatation joint in order to bridge the dilatation joint.



   Most of the expansion joints on railway tracks are nowadays completely closed by welding, which means that rail sections of any length without expansion joints can be installed with professional sleeper anchoring.



   In curves, expansion joints must be provided at certain intervals, depending on the curve radius, as otherwise the lateral deflection forces from temperature stresses become too great.



   The invention is based on the object of bridging expansion joints in rails.



   According to the invention, this is achieved by inserting a wedge horizontally into the adjacent ends of the splint at the dilatation joint, i.e. H. is introduced into the upper longitudinal recesses of the rail heads.



   The rail wedge is preferably made of metal, in particular steel of a class of goods which at least corresponds to that of the rail.

 

   An exemplary embodiment is described in more detail below with reference to the accompanying drawings. Show it
1 shows a cross section,
2 shows a longitudinal section,
3 is a view from above of the installed rail wedge.



   The rail wedge 1 shown in the drawing with a small wedge angle has a distance from the material of the rail head 2 at both ends which is slightly greater than half the distance between the rails in the dilatation joint 3.



   By using the rail wedge, firstly, the noise of the wheel joint when driving over the expansion joint is reduced to a minimum, secondly, damage to the wheels and thirdly that of the rail ends is prevented, which in addition to the greatly reduced noise emission results in reduced maintenance costs for the wheels and the rails.
