Alle diesbezüglichen Lösungsvorschläge gehen davon aus, dass das Rillenschienenherzstück im Bereich der sich kreuzenden Rillen aus einem homogenen Material besteht, wobei im mehr oder weniger großen Abstand vom Schnittpunkt der Rillen eine Verbindung mit den Anschlussschienen erfolgt.All related solutions suggest that the grooved rail frog in the area of the intersecting grooves, consists of a homogeneous material, in more or less large distance from the intersection of the grooves connect with the Connecting rails done.

Ein in der DE-C 452 341 beschriebenes Herzstück für Rillenschienen-Gleisanlagen besteht aus zwei Rillenschienenherzstücken, die entsprechend der Herzstückneigung abgeknickt und mit ihren an den Kopfseiten angearbeiteten Flächen gegeneinandergelegt und über Schrauben verbunden sind. Bei den Rillenschienenstücken kann es sich um Abschnitte von Vollkopfschienen handeln, die entsprechend gebogen sind. Hierzu sind besondere Bearbeitungsmaschinen erforderlich.There is a heart for grooved rail track systems described in DE-C 452 341 from two grooved rail frogs, which are bent according to the center piece inclination and with their surfaces worked on the head sides against each other and over screws are connected. The grooved rail pieces may be sections of full head rails act accordingly bent. These are special processing machines required.

Ein Herzstück mit Flügelschienen nach dem DE 81 05 454 U1 weist einen im Bereich der Herzstückspitze umfassenden Einsatz auf, der aus einem eine hohe Verschleißfestigkeit aufweisenden Material besteht.A heart with wing rails according to DE 81 05 454 U1 has a in the field of Full centerpiece use on top, resulting in a high wear resistance comprising material.

Bei einem Herzstück mit entlang diesem verlaufenden Flügelschienen nach der DE 42 24 156 A1 sind die das Herzstück bildenden Schienenabschnitte mit den Flügelschienen über eine Schraubverbindung verbunden, die ihrerseits eine Hülse durchsetzt, die sich spielfrei in dem Herzstück erstreckt. Dabei können die das Herzstück bildenden Schienenabschnitte durch zum Beispiel Verzahnung formschlüssig miteinander verbunden sein.At a heart with along this extending wing rails according to DE 42 24 156 A1 are the core forming rail sections with the wing rails over a Connected screw, which in turn passes through a sleeve, the backlash in the Centerpiece extends. In this case, the core piece forming rail sections For example, teeth are positively connected to each other.

Ein gattungsgemäßes Rillenschienenherzstück ist aus der US-A 554, 320 bekannt. Das gesamte Rillenschienenherzstück besteht aus Schienenabschnitten, die über Schrauben kraftschlüssig miteinander verbunden sind.A generic grooved rail frog is known from US-A 554, 320. The entire grooved rail frog consists of rail sections that have screws are positively connected with each other.

Ein Rillenschienenherzstück nach der US-A 1 878 984 weist im Schnittpunktbereich ein U-förmiges Einsatzstück auf, unterhalb dem sich Konstruktionsprofile erstrecken, die vor und hinter dem Einsatz die Führungsfunktion für die den Herzstückbereich durchlaufenden Räder ausüben.A grooved rail frog according to US-A 1 878 984 has a U-shaped in the intersection area Insert on, below which construction profiles extend, the before and Behind the insert, the guiding function for the wheels passing through the center piece area exercise.

Zwei V-förmig gebogene Schienen, die quer zur Längsrichtung eines Herzstücks stumpf verschweißt sind, werden zur Ausbildung eines solchen nach der DE-C 712 843 verwendet. Two V-shaped curved rails that dull transversely to the longitudinal direction of a heart are welded, are used to form such according to DE-C 712 843.

Der vorliegenden Erfindung liegt das Problem zu Grunde, ein Rillenschienenherzstück sowie ein Verfahren zum Herstellen eines solchen derart weiterzubilden, dass bei einfacher Konstruktion nur wenig Bauteile zu dessen Herstellung erforderlich sind. Dabei soll insbesondere die Möglichkeit gegeben sein, starken Beanspruchungen ausgesetzte Teile verschleißfest auszubilden.The present invention is based on the problem, a grooved rail frog as well to develop a method for producing such that with a simple construction only a few components are required for its production. It should in particular be given the opportunity to wear parts exposed to heavy wear train.

Erfindungsgemäß wird das Problem im Wesentlichen dadurch gelöst, dass die Konstruktionsprofile im Herzstückschnittpunktbereich zur Aufnahme eines verschleißfesten Einsatzes Ausnehmungen aufweisen und dass der Einsatz mit den Konstruktionsprofilen zum einen formschlüssig und zum anderen kraftschlüssig über Schraubverbindungen verbunden ist, die unterhalb des Einsatzes die Konstruktionsprofile durchsetzen.According to the invention, the problem is solved essentially by the fact that the construction profiles in the center section area for receiving a wear-resistant insert Have recesses and that the use of the construction profiles on the one hand positively and on the other non-positively connected via screw, the enforce the construction profiles below the insert.

Insbesondere ist vorgesehen, dass die zumindest den Herzstückschnittpunktbereich bildenden Konstruktionsprofile kraft- und formschlüssig verbunden sind, wobei insbesondere ein Verbinden durch die Konstruktionsprofile bzw. deren Stege durchsetzende Schraubverbindungen hochfest verbunden sind.In particular, it is provided that the at least the frog intersection region forming Construction profiles are positively and positively connected, in particular a Connecting through the construction profiles or their webs passing through Screw connections are connected high-strength.

Dabei sind die Konstruktionsprofile selbst über deren Stege durchsetzende Schraubverbindungen hochfest miteinander verbunden. Hochfest bedeutet dabei, dass die Schienen unter planmäßiger Vorspannung, d. h. vorgegebenem Drehmoment verbunden sind, wobei insbesondere zur Verdrehsicherung die Schrauben sichernde Muttern sowie gegebenenfalls NORD-LOCK®-Sicherungen (Schraubensicherungssystem, bei dem Schraubenverbindungen durch Vorspannung gesichert werden) benuizt werden. Bei der diesbezüglichen Ausgestaltung der erfindungsgemäßen Lehre ist der Herzstückschnittpunkt- wie Radüberlaufbereich des Rillenschienenherzstücks ebenfalls nicht als Block ausgebildet, sondern besteht aus aus mittleren Abschnitten von in Längsrichtung des Herzstücks verlaufenden kraft- und formschlüssig verbundenen Konstruktionsprofilen wie Dickstegschienen oder Walzblöcken, die im Ausgangszustand ein Vollkopfprofil aufweisen, in das nach der Verbindung der Konstruktionsprofile die Rillen eingearbeitet werden. An die mittleren Abschnitte schließen sich sodann die weggebogenen Schenkel als äußere Abschnitte an, die nach dem Stand der Technik auch als Anschweißschienen bezeichnet werden.The construction profiles are self-enforcing screw connections through their webs high-strength connected. Hochfest means that the rails under scheduled preload, d. H. are connected to predetermined torque, in particular to prevent rotation, the nuts securing the screws and, if necessary NORD-LOCK® fuses (screw locking system, with screw connections be secured by bias) benuizt be. In the relevant Embodiment of the teaching of the invention is the heart piece intersection-like Wheel overflow area of the grooved rail frog also not formed as a block, but consists of middle sections of in the longitudinal direction of the heart running force and form-fitting connected construction profiles such Thick web rails or rolling blocks, which have a full head profile in the initial state, in which after the connection of the construction profiles the grooves are incorporated. To the middle sections then close the bent-away legs as outer sections on, which are referred to in the prior art as welding rails.

Bei ersterer Lösung sind die Konstruktionsprofile entsprechend gebogen.According to the invention, a grooved rail frog is proposed, the Center section area consisting of sections of unbent construction profiles, the legs of the grooved rail frog either sections of the Construction profiles are connected or welded to them. At the former Solution, the construction profiles are bent accordingly.

Bei dem mehrteiligen Rillenschienenherzstück sind insbesondere Biegearbeiten an den verwendeten Bauteilen nicht erforderlich, so dass aufwendige Maschinen nicht benötigt werden. Ungeachtet dessen ist es jedoch nicht erforderlich, dass der Herzstückschnittpunktbereich einteilig ausgebildet ist, wodurch andernfalls herstellungstechnisch erhebliche Nachteile gegeben sein können.In the multi-part grooved rail frog in particular bending work on the used components not required, so that consuming machines not needed become. Nevertheless, it is not necessary that the Centerpiece intersection region is integrally formed, whereby otherwise Manufacturing technology can be given significant disadvantages.

Unabhängig von der erfindungsgemäßen Konstruktion, ob diese folglich allein aus zwei entsprechenden gebogenen Konstruktionsprofilen oder aus zwei geradlinig verlaufenden Abschnitten von Konstruktionsprofilen und mit diesen verschweißten Schenkeln bestehen, sieht die Erfindung vor, dass die Konstruktionsprofile in ihren aufeinanderliegenden Fügeflächen formschlüssig durch z. B. Verzahnung oder Hinterschneidung ineinandergreifen.Regardless of the construction according to the invention, whether this alone of two corresponding curved construction profiles or from two rectilinear running Sections of structural profiles and legs welded to them, the invention provides that the construction profiles in their superimposed Joining surfaces form fit by z.

Um eine erforderliche Vorspannung des Einsatzes zu gewährleisten, ist in Weiterbildung der Erfindung vorgesehen, dass die Konstruktionsprofile außenseitig eine Laschenkammer aufweisen, in die von der Schraubverbindung durchsetzte Stützlaschen angeordnet sind. Hierdurch wird die Vorspannkraft in Bereichen geringerer Widerstandsmomente in die Einspannung des Einsatzes geleitet.In order to ensure a required bias of the insert, is in the development of Invention provided that the construction profiles on the outside have a tab chamber, are arranged in the penetrated by the screw support tabs. hereby is the biasing force in areas of lower moments of resistance in the clamping of the mission.
