Definitions
- the invention relates to a heart piece with a heart tip and wing splints which are connected to the heart tip, in which the wing splints are welded to the heart tip using lining pieces.
- heart tips with cast-on or welded-on lining pieces are also known for the production of heart pieces, the wing rails being screwed onto the heart tip by means of the lining pieces.
- the chucks serve to keep the distance and the high-strength screw connection is exposed to various loads in use, which make frequent maintenance and inspection necessary.
- the forces that occur in the track, which is laid without gaps, result in a relative movement between the apex of the heart and the wing rails, which on the one hand loosens the screw connection and on the other hand introduces additional shear forces and tensile forces into the screw connection.
- block frogs are often used in which the frog tip is formed in one piece with the wing rails.
- the vibrations occurring in the track are introduced into the entire block frog consisting of the frog tip and wing rails there are a number of disturbing factors in the vibration behavior compared to the rest of the track.
- the centerpiece according to the invention essentially consists in the fact that the lining pieces have a lower height in the welding position than the web of the wing rails.
- Such chucks allow the elasticity of the wing splints in the vertical direction while ensuring the desired elasticity of the welded joint and ensure that the vibrations of the track are only transmitted to the part directly connected to these rails and thus to the wing splints or the apex of the heart, the rigid Coupling between the apex of the heart and wing splints is released. Since the screw connections are omitted, the maintenance effort is significantly reduced.
- the fact that lining pieces are used avoids the disadvantages of center block centerpieces or monoblock centerpieces, in which a continuous groove generally remains between the wing rail and the centerpiece, which can result in malfunctions in operation. Furthermore, with such monoblock or middle block heart pieces, subsequent bending of the heart piece for curved switches is generally difficult.
- the elastic construction according to the invention using welded lining pieces such adjustments to the heart of the turnout.
- the design according to the invention is such that the lining pieces are formed by plate-shaped elements, the main plane of which extends in the longitudinal direction of the rail.
- Such plate-shaped elements as lining pieces with the main plane running in the longitudinal direction of the rails are capable of absorbing the relative movements between the apex of the heart and the wing rail without this leading to excessive stress on the weld seams.
- the height of the plate-shaped elements can advantageously be less than the width of the elements between the tip of the heart and the wing splint in order to allow relative movements between the heart tip and the wing splint.
- Particularly favorable vibration-damping properties can be achieved if the length of the lining pieces corresponds to half to three times the width of the lining pieces.
- the width of the chuck is dependent on the rail profile.
- the height of the pieces of lining can advantageously correspond to one to two thirds of the width, preferably approximately half of the width, which enables the oscillation of the wing splints to be largely decoupled from vibrations of the tip of the heart introduced via the heart connecting splints.
- Such dimensioning which is only to be taken into account in the case of chucks between the frog tip and wing splints, has, in addition to the advantageous vibration properties, the advantage that the susceptibility to faults can be further reduced by spacing the chucks in the longitudinal direction of the wing splints or the heart tip are arranged, which corresponds to three to five times the length of the feed pieces. A continuous groove between the tip of the heart and the wing splints is thus avoided, so that there is also a groove in this groove Accumulation of material that could give rise to faults cannot occur.
- a particularly stable design can be achieved in that the wing splints near the apex are also welded to one another with at least one lining piece, the relative movement between the wing splints and the apex being in no way impaired by such a direct welding of the wing splints using a lining piece.
- the wing rails can be further fixed to the heart connection rails in a conventional manner by means of screwed chuck pieces, the remaining stress on the screw connection in the screw axis being low by moving the wheels at the rear wing rail inlet and no maintenance effort being required when using a screw lock.

- Wing rail connection rails or control rails 7 and 8 are connected to the wing rails 4 and 5.
- the wing rails 4 and 5 are screwed to the heart connection rails 2 and 3 by means of chucks 9.
- one or more chucks 10 are welded in front of the frog tip between the wing rails.
- the selected lining pieces 6, which are respectively welded to the wing rails 4 and 5, have a height a which is significantly less than the height b of the web of the wing rails 4.
- the lining pieces 6 are formed by plate-shaped elements, the main plane of which extends in the longitudinal direction of the wing rails 4 or the connecting rails. The length in this longitudinal direction c is significantly greater than the height a of the plate-shaped elements which are used as lining pieces 6.
- the heart tip 1 is formed as a composite material in the embodiment according to FIG. 3 and carries a highly wear-resistant material at the wheel overflow point.
- the tip of the heart can be made of composite material or cast manganese steel. It is also possible to design the wing rails from composite material or from rolled manganese steel.
- connection between wing rail and cardiac tip is made by welding in the spacers 6, depending on the choice of material for the cardiac tip and the wing rails, a material must be selected that ensures the perfect welding of these materials in the combinations mentioned as a material for the execution of the center piece can be selected a composite workpiece, the wheel tread of a hardenable steel with the composition C 0.01 to 0.05% Si 0.01 to 0.2% Mn 0.01 to 0.2% Co 0 to 15% Mo 1.5 to 6% Ni 7 to 20% Ti 0.1 to 1% Cr 0 to 13% Al 0 to 0.2% B 0 to 0.1% Zr 0 to 0.1% is trained.

Abstract
Description
Die Erfindung bezieht sich auf ein Herzstück mit einer Herzspitze und Flügelschienen, welche mit der Herzspitze verbunden sind, bei welchem die Flügelschienen unter Verwendung von Futterstücken mit der Herzspitze verschweißt sind.The invention relates to a heart piece with a heart tip and wing splints which are connected to the heart tip, in which the wing splints are welded to the heart tip using lining pieces.
Aus der DE-PS 1 161 574 ist ein Herzstück aus aluminothermisch miteinander verschweißten Vignolschienen bekanntgeworden, bei welchem Futterstücke mit der Herzspitze und den Flügelschienen jeweils am Schienenkopf und Schienenfuß verschweißt werden, wodurch Schrumpfspannungen vermieden werden sollen. Nachteilig bei dieser bekannten Ausbildung ist, daß die Futterstücke eine spezielle Form für ein Anliegen an Schienenfuß und Schienenkopf aufweisen müssen.From DE-PS 1 161 574 a frog made of aluminothermic Vignol rails has become known, in which fodder pieces are welded to the top of the heart and the wing rails on the rail head and rail base, whereby shrinkage stresses are to be avoided. A disadvantage of this known design is that the lining pieces have to have a special shape for contact with the rail foot and rail head.
Für die Herstellung von Herzstücken sind weiters in der sogenannten Profilblockbauart Herzspitzen mit angegossenen oder angeschweißten Futterstücken bekannt, wobei die Flügelschienen mittels der Futterstücke an die Herzspitze angeschraubt werden. Die Futterstücke dienen dabei der Distanzhaltung und die hochfeste Schraubverbindung ist im Einsatz verschiedenen Belastungen ausgesetzt, welche eine häufige Wartung und Kontrolle erforderlich machen. Durch die Kräfte, die im lückenlos verlegten Gleis auftreten, erfolgt eine Relativbewegung zwischen Herzspitze und den Flügelschienen, wodurch einerseits die Schraubverbindung gelockert wird und andererseits zusätzliche Scherkräfte und Zugkräfte in die Schraubverbindung eingeleitet werden.In the so-called profile block design, heart tips with cast-on or welded-on lining pieces are also known for the production of heart pieces, the wing rails being screwed onto the heart tip by means of the lining pieces. The chucks serve to keep the distance and the high-strength screw connection is exposed to various loads in use, which make frequent maintenance and inspection necessary. The forces that occur in the track, which is laid without gaps, result in a relative movement between the apex of the heart and the wing rails, which on the one hand loosens the screw connection and on the other hand introduces additional shear forces and tensile forces into the screw connection.
Um den Wartungsaufwand derartiger Herzstücke zu vermindern werden häufig Blockherzstücke eingesetzt, bei welchen die Herzstückspitze einstückig mit den Flügelschienen ausgebildet ist. Bei derartigen Ausbildungen werden die im Gleis auftretenden Schwingungen in das gesamte, aus Herzstückspitze und Flügelschienen bestehende Blockherzstück eingeleitet und es entstehen eine Reihe von Störfaktoren im Schwingungsverhalten gegenüber dem übrigen Geleise.In order to reduce the maintenance effort of such frogs, block frogs are often used in which the frog tip is formed in one piece with the wing rails. In such designs, the vibrations occurring in the track are introduced into the entire block frog consisting of the frog tip and wing rails there are a number of disturbing factors in the vibration behavior compared to the rest of the track.
Die Erfindung zielt nun darauf ab, ein Herzstück der eingangs genannten Art zu schaffen, welches ein gegenüber bekannten Herzstücken günstigeres, insbesondere störungsfreies Schwingungsverhalten aufweist und nur einen geringen Wartungsaufwand erfordert. Zur Lösung dieser Aufgabe besteht das erfindungsgemäße Herzstück im wesentlichen darin, daß die Futterstücke in der Schweißlage eine geringere Höhe aufweisen als der Steg der Flügelschienen. Durch die Verwendung von zwischen Flügelschienen und Herzstück eingeschweißten, in der Schweißlage eine geringere Höhe als der Steg der Flügelschienen aufweisenden Futterstücken kann insgesamt eine elastische Bauweise erzielt werden, bei welcher durch das Schwingungsverhalten der Herzstückspitze das Schwingungsverhalten des übrigen Gleises weitgehend ungestört verbleibt. Derartige Futterstücke erlauben bei Sicherstellung der gewünschten Elastizität der Schweißverbindung ein elastisches Ausweichen der Flügelschienen in Höhenrichtung und stellen sicher, daß die Schwingungen des Geleises nur jeweils auf den unmittelbar mit diesen Geleisen verbundenen Teil und somit auf die Flügelschienen oder die Herzspitze übertragen werden, wobei die starre Kopplung zwischen Herzspitze und Flügelschienen aufgehoben ist. Da die Schraubverbindungen entfallen, wird der Wartungsaufwand wesentlich verringert. Dadurch, daß Futterstücke verwendet werden, werden die Nachteile von Mittelblockherzstücken oder Monoblockherzstücken vermieden, bei welchen in der Regel eine durchgehende Rille zwischen Flügelschiene und Herzstück verbleibt, wodurch sich Störungen im Betrieb ergeben können. Weiters ist bei derartigen Monoblock- bzw. Mittelblockherzstücken eine nachträgliche Verbiegung des Herzstückes für Bogenweichen in der Regel erschwert möglich. Demgegenüber erlaubt die erfindungsgemäße elastische Bauweise unter Verwendung von angeschweißten Futterstücken auch derartige Anpassungen des Herzstückes für Bogenweichen.The invention is now aimed at creating a heart of the type mentioned at the outset, which has a more favorable, in particular trouble-free, vibration behavior than known heart pieces and requires little maintenance. To achieve this object, the centerpiece according to the invention essentially consists in the fact that the lining pieces have a lower height in the welding position than the web of the wing rails. By using welded in between the wing rails and the centerpiece, which has a lower height than the web of the wing rails in the weld position, an elastic construction can be achieved, in which the vibration behavior of the centerpiece tip largely remains undisturbed by the vibration behavior of the centerpiece tip. Such chucks allow the elasticity of the wing splints in the vertical direction while ensuring the desired elasticity of the welded joint and ensure that the vibrations of the track are only transmitted to the part directly connected to these rails and thus to the wing splints or the apex of the heart, the rigid Coupling between the apex of the heart and wing splints is released. Since the screw connections are omitted, the maintenance effort is significantly reduced. The fact that lining pieces are used avoids the disadvantages of center block centerpieces or monoblock centerpieces, in which a continuous groove generally remains between the wing rail and the centerpiece, which can result in malfunctions in operation. Furthermore, with such monoblock or middle block heart pieces, subsequent bending of the heart piece for curved switches is generally difficult. In contrast, the elastic construction according to the invention using welded lining pieces such adjustments to the heart of the turnout.
In besonders vorteilhafter Weise ist die erfindungsgemäße Ausbildung so getroffen, daß die Futterstücke von plattenförmigen Elementen gebildet sind, deren Hauptebene in Längsrichtung der Schiene verläuft. Derartige plattenförmige Elemente als Futterstücke mit in Längsrichtung der Schienen verlaufender Hauptebene sind in der Lage, die Relativbewegungen zwischen Herzspitze und Flügelschiene aufzunehmen, ohne daß dies zu einer Überbeanspruchung der Schweißnähte führt. Die Höhe der plattenförmigen Elemente kann hiebei mit Vorteil geringer sein als die Breite der Elemente zwischen Herzspitze und Flügelschiene, um Relativbewegungen zwischen Herzspitze und Flügelschiene zu erlauben. Besonders günstige schwingungsdämpfende Eigenschaften können dann erzielt werden, wenn die Länge der Futterstücke der halben bis dreifachen Breite der Futterstücke entspricht. Die Breite der Futterstücke ist hiebei in Abhängigkeit vom Schienenprofil zu bemessen. Bei einer derartigen Ausbildung kann die Höhe der Futterstücke mit Vorteil einem bis zwei Drittel der Breite, vorzugsweise etwa der Hälfte der Breite entsprechen, wodurch eine weitgehende Entkopplung der Schwingung der Flügelschienen von über die Herzanschlußschienen eingebrachten Schwingungen der Herzspitze ermöglicht wird. Eine derartige Dimensionierung, welche nur bei Futterstücken zwischen Herzstückspitze und Flügelschienen zu berücksichtigen ist, hat neben den vorteilhaften schwingungstechnischen Eigenschaften auch den Vorteil, daß die Störanfälligkeit dadurch weiter verringert werden kann, daß die Futterstücke in Längsrichtung der Flügelschienen bzw. der Herzspitze in einem Abstand voneinander angeordnet sind, welcher dem drei bis fünffachen der Länge der Futterstücke entspricht. Es wird somit eine durchgehende Rille zwischen Herzspitze und Flügelschienen vermieden, sodaß in dieser Rille auch eine Ansammlung von Material, welche zu Störungen Anlaß geben könnte, nicht auftreten kann.In a particularly advantageous manner, the design according to the invention is such that the lining pieces are formed by plate-shaped elements, the main plane of which extends in the longitudinal direction of the rail. Such plate-shaped elements as lining pieces with the main plane running in the longitudinal direction of the rails are capable of absorbing the relative movements between the apex of the heart and the wing rail without this leading to excessive stress on the weld seams. The height of the plate-shaped elements can advantageously be less than the width of the elements between the tip of the heart and the wing splint in order to allow relative movements between the heart tip and the wing splint. Particularly favorable vibration-damping properties can be achieved if the length of the lining pieces corresponds to half to three times the width of the lining pieces. The width of the chuck is dependent on the rail profile. With such a design, the height of the pieces of lining can advantageously correspond to one to two thirds of the width, preferably approximately half of the width, which enables the oscillation of the wing splints to be largely decoupled from vibrations of the tip of the heart introduced via the heart connecting splints. Such dimensioning, which is only to be taken into account in the case of chucks between the frog tip and wing splints, has, in addition to the advantageous vibration properties, the advantage that the susceptibility to faults can be further reduced by spacing the chucks in the longitudinal direction of the wing splints or the heart tip are arranged, which corresponds to three to five times the length of the feed pieces. A continuous groove between the tip of the heart and the wing splints is thus avoided, so that there is also a groove in this groove Accumulation of material that could give rise to faults cannot occur.
Eine besonders stabile Ausbildung läßt sich dadurch erzielen, daß die Flügelschienen nahe der Herzspitze gleichfalls mit wenigstens einem Futterstück miteinander verschweißt sind, wobei durch eine derartige direkte Verschweißung der Flügelschienen unter Verwendung eines Futterstückes die Relativbewegung zwischen den Flügelschienen und der Herzspitze in keiner Weise beeinträchtigt wird.A particularly stable design can be achieved in that the wing splints near the apex are also welded to one another with at least one lining piece, the relative movement between the wing splints and the apex being in no way impaired by such a direct welding of the wing splints using a lining piece.
Im Anschluß an die Herzspitze kann eine weitere Festlegung der Flügelschienen an den Herzanschlußschienen in konventioneller Weise mittels verschraubter Futterstücke erfolgen, wobei die verbleibende Beanspruchung der Schraubverbindung in Schraubenachse durch das Anfahren der Räder am rückwärtigen Flügelschieneneinlauf gering ist und kein Wartungsaufwand bei Verwendung einer Schraubensicherung erforderlich ist.Following the tip of the heart, the wing rails can be further fixed to the heart connection rails in a conventional manner by means of screwed chuck pieces, the remaining stress on the screw connection in the screw axis being low by moving the wheels at the rear wing rail inlet and no maintenance effort being required when using a screw lock.
Die Erfindung wird nachfolgend an Hand eines in der Zeichnung schematisch dargestellten Ausführungsbeispieles näher erläutert. In dieser zeigen: Fig. 1 eine Draufsicht auf ein erfindungsgemäßes Herzstück, Fig. 2 einen Schnitt nach der Linie II-II der Fig. 1 und Fig. 3 einen Schnitt nach der Linie III-III der Fig. 1.The invention is explained in more detail below on the basis of an exemplary embodiment schematically illustrated in the drawing. 1 shows a plan view of a centerpiece according to the invention, FIG. 2 shows a section along the line II-II of FIG. 1 and FIG. 3 shows a section along the line III-III of FIG. 1.
In Fig. 1 ist eine Herzspitze 1 dargestellt, mit welcher Herzanschlußschienen 2 und 3 verbunden sind. Seitlich der Herzspitze 1 sind Flügelschienen 4 und 5 vorgesehen, welche über Futterstücke 6 mit der Herzspitze 1 verschweißt sind. An die Flügelschienen 4 und 5 sind Flügelschienenanschlußschienen bzw. Regelschienen 7 und 8 angeschlossen. Die Flügelschienen 4 und 5 sind mit den Herzanschlußschienen 2 und 3 mittels Futterstücken 9 verschraubt. Außerdem werden ein oder mehrere Futterstücke 10 vor der Herzstückspitze zwischen den Flügelschienen eingeschweißt.In Fig. 1, a
Im Schnitt nach der Fig. 2 ist ersichtlich, daß die gewählten Futterstücke 6, welche jeweils mit den Flügelschienen 4 und 5 verschweißt sind, eine Höhe a aufweisen, welche deutlich geringer ist als die Höhe b des Steges der Flügelschienen 4. Die Futterstücke 6 sind von plattenförmigen Elementen gebildet, deren Hauptebene in Längsrichtung der Flügelschienen 4 bzw. der Anschlußschienen verläuft. Die Länge in dieser Längsrichtung c ist deutlich größer als die Höhe a der plattenförmigen Elemente, welche als Futterstücke 6 zum Einsatz gelangen.In the section according to FIG. 2 it can be seen that the
In Fig. 3 ist die Breite d der plattenförmigen Elemente 6 und die Art der Verschweißung der Futterstücke bzw. plattenförmigen Elemente 6 mit den Flügelschienen 4 und 5 und der Herzspitze 1 ersichtlich. Die Herzspitze 1 ist bei der Ausbildung nach Fig. 3 als Verbundwerkstoff ausgebildet und trägt an der Radüberlaufstelle einen höchstverschleißfesten Werkstoff. Bei der Auswahl der Werkstoffe für die Ausführung des Herzstückes sind ebenso wie bei der Auswahl des Werkstoffes für die Flügelschienen unterschiedliche Möglichkeiten offen. Die Herzspitze kann aus Verbundwerkstoff oder auch aus Manganhartstahlguß bestehen. Ebenso ist es möglich, die Flügelschienen aus Verbundwerkstoff oder aus gewalztem Manganhartstahl auszubilden. Die Verbindung zwischen Flügelschiene und Herzspitze erfolgt jeweils durch Einschweißung der Distanzstücke 6, wobei je nach Wahl des Materials für die Herzspitze und die Flügelschienen ein Werkstoff gewählt werden muß, der die einwandfreie Verschweißung dieser Werkstoffe in den genannten Kombinationen gewährleistet Als Werkstoff für die Ausführung des Herzstückes kann ein Verbundwerkstück gewählt werden, dessen Radlauffläche aus einem aushärtbaren Stahl mit der Zusammensetzung C 0,01 bis 0,05 %
Si 0,01 bis 0,2 %
Mn 0,01 bis 0,2 %
Co 0 bis 15 %
Mo 1,5 bis 6 %
Ni 7 bis 20 %
Ti 0,1 bis 1 %
Cr 0 bis 13 %
Al 0 bis 0,2 %
B 0 bis 0,1 %
Zr 0 bis 0,1 %
ausgebildet ist. Ein derartiger Stahl ist gut schweißbar und in lösungsgeglühtem Zustand gut bearbeitbar. Derartige Stahlsorten zeichnen sich dadurch aus, daß sie durch Auslagerung bei 200°C bis 600°C eine sehr hohe Härte bei guter Zähigkeit annehmen, die durch Martensitumwandlung und/oder Ausscheidung intermetallischer Phasen erreicht wird. Die Flügelschienen können ebenfalls aus einem Verbundwerkstoff dieser Art bestehen oder aber beispielsweise aus Manganhartstahl gewalzt sein. Darüberhinaus besteht naturgemäß die Möglichkeit die Herzspitze in bekannter Weise aus Manganhartstahlguß zu fertigen, wobei die Flügelschienen gleichfalls aus Manganhartstahl gefertigt sein können, um die Verschweißung und die nachfolgende Temperaturbehandlung zu vereinfachen. Während des Schweißvorganges muß entsprechend den gewählten Ausgangsmaterialien eine gezielte Temperaturführung beachtet werden, wobei die Positionierung der Distanzstücke in Hinblick auf ein verbessertes Schwingungsverhalten der Gesamtkonstruktion erfolgt.In Fig. 3, the width d of the plate-

is trained. Such a steel is easy to weld and easy to machine in the solution-annealed condition. Steel grades of this type are distinguished by the fact that, by aging at 200 ° C. to 600 ° C., they assume a very high hardness with good toughness, which is achieved by martensitic transformation and / or precipitation of intermetallic phases. The wing rails can also consist of a composite material of this type or can be rolled, for example, from high manganese steel. In addition, there is of course the possibility to manufacture the tip of the heart from cast manganese steel in a known manner, and the wing rails can also be made from manganese steel in order to simplify the welding and the subsequent temperature treatment. During the welding process, a targeted temperature control must be observed in accordance with the selected starting materials, the spacers being positioned with a view to improving the vibration behavior of the overall construction.
