Description

Beschreibungdescription
GleisabschnittTrack section
Die Erfindung bezieht sich auf einen Gleisabschnitt in Form eines aus zwei Schienenabschnitten zusammengesetzten Herzstücks und über Futterstücke beabstandete Flügelschienen, wobei zumindest das Herzstück von einer ein Verbindungselement wie Bolzen umgebenden Hülse durchsetzt ist.The invention relates to a track section in the form of a centerpiece composed of two rail sections and wing rails spaced apart by lining pieces, at least the centerpiece being penetrated by a sleeve surrounding a connecting element such as bolts.
Herzstücke ergeben sich bei Weichen oder Kreuzungen durch Überschneidungen von Schienensträngen. Dabei gibt es einfache, doppelte, zwei- und dreifache Herzstücke, wobei allerdings am häufigsten das einfache Herzstück bei einfachen Weichen vorzufinden ist.The heart of switches or crossings is the result of overlapping rail tracks. There are simple, double, double and triple frogs, although the single frog is most often found on simple turnouts.
Im Herzstück sind die Fahrkanten der sich kreuzenden Schienenstränge unter¬ brochen. Die sich von den Zungen her fortsetzenden Schienenstränge werden im Herzstückbereich abgeknickt und als Flügelschienen bezeichnet. Die beiden von den Weichenenden her sich fortsetzenden Stränge werden zur Herzstückspitze zusammengeführt. Dabei kann man die Spitze entweder aus Regelschienen zusammensetzen (Schienenherzstück), aus Konstruktionsschienen zusammensetzen und teilweise verschweißen (Teilblockherzstück) oder aus einem Stück herstellen (Blockherzstück). Letztere werden z. B. bei der Deutschen Bundesbahn nur noch selten verwendet.The driving edges of the crossing rail tracks are interrupted in the centerpiece. The rail strands that continue from the tongues are bent in the frog area and are referred to as wing rails. The two strands, which continue from the turnout ends, are brought together to the centerpiece tip. The tip can either be composed of standard rails (rail frog), composed of construction rails and partially welded (partial block frog) or made from one piece (block frog). The latter are e.g. B. only rarely used in the Deutsche Bundesbahn.
Bei Herzstücken, die aus Schienen hergestellt werden, erfolgt häufig ein Ver¬ schweißen dieser. Hierbei können sich jedoch dann Nachteile ergeben, wenn schwer schweißbare Materialien verbunden werden sollen. Nachteilig ist ferner, daß in der Stoßfläche Fremdmaterial vorhanden ist. Randentkohlungen sind ebenfalls nachteilig. Ferner erwächst die Gefahr von Rissen.In the case of frogs which are produced from rails, they are often welded together. However, disadvantages can arise here if materials that are difficult to weld are to be connected. Another disadvantage is that in the Butt surface foreign material is present. Edge decarburization is also disadvantageous. The risk of cracks also increases.
Sofern die Gleisteile nicht miteinander verschweißt sind, werden diese über Verbindungselemente wie Bolzen zusammengehalten. Hierbei ist jedoch nachteilig, daß eine Relativbewegung zwischen den Schienenteilen erfolgt.If the track parts are not welded together, they are held together by connecting elements such as bolts. However, it is disadvantageous that there is a relative movement between the rail parts.
Verschiedene Konstruktionen von Herzstücken sind den DD 60 326, DE 548 749, DE 23 18 419, D E 81 05 454 U l oder DD 60 326 zu entnehmen.Different constructions of frogs can be found in DD 60 326, DE 548 749, DE 23 18 419, D E 81 05 454 U l or DD 60 326.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Herzstück der eingangs beschriebenen Art derart weiterzubilden, daß sich ohne Schweißen miteinander verbundene Schienenteile zumindest senkrecht zur Längsachse des Gleisabschnitts relativ zueinander nicht bewegen können.The present invention has for its object to develop a core of the type described in such a way that rail parts interconnected without welding can not move relative to each other at least perpendicular to the longitudinal axis of the track section.
Die Aufgabe wird erfindungsgemäß im wesentlichen zum einen dadurch gelöst, daß das Herzstück aus unverschweißten Schienenabschnitten besteht, die von der Hülse spielfrei durchsetzt sind. Dabei sind vorzugsweise die Herzstückabschnitte vollständig und die zu dessen beiden Seiten angeordneten und die zugeordneten Flügelschienen beabstandenden Futterstücke zumindest bereichsweise von der Hülse durchsetzt.The object is essentially achieved on the one hand in that the heart consists of unwelded rail sections which are penetrated by the sleeve without play. In this case, the frog sections are preferably completely penetrated by the sleeve, at least in regions, the lining pieces arranged on its two sides and spacing the associated wing rails.
Die Aufgabe wird bei einem Gleisabschnitt mit gegebenenfalls bereichsweise von einer Hülse umgebenen Verbindungselement wie Bolzen durchsetzten aus zwei Schienenabschnitten zusammengesetztem Herzstück und diesem zugeordneten, über Futteretücke zueinander beabstandeten Flügelschienen auch dadurch gelöst, daß unverschweißte das Herzstück bildende Herzstückabschnitte einerseits und die zu dessen beiden Seiten angeordneten und die zugeordneten Flügelschienen beabstandenden Futterstücke andererseits mit über jeweils in Längsrichtung des Herzstücks verlaufender Profilierungformschlüssig ineinandergreifen. Insbesondere ist vorgesehen, daß die Profilierung aus einer durch von aufeinande liegenden Flächen von Herzstück und Futterstücken ausgehenden Zähne gebildeten Ver¬ zahnung besteht.The task is solved in a track section with a connection element, such as a bolt, which may be surrounded by a sleeve, consisting of two rail sections and the associated wing piece, which is spaced apart from one another by lining pieces, in that unwelded heart piece sections forming the heart piece, on the one hand, and those arranged on both sides, and the associated wing rails spacing pieces of chuck on the other hand interlock positively with each other over profiling extending in the longitudinal direction of the heart. In particular, it is provided that the profiling consists of one on top of the other Teeth formed from the surfaces of the centerpiece and lining pieces of teeth.
Durch die erfindungsgemäßen Lehren ist auf einfache Weise sichergestellt, daß zwischen den zu verbindenden Schienenteilen eine Relativbewegung senkrecht zur Längsachse nicht auftreten kann, ohne daß in diesem Verbindungsbereich, insbesondere in dem von dem Verbindungselement durchsetzten Herzstückbereich ein Schweißen erforderlich ist. Folglich treten weder Probleme mit Randentkohlun¬ gen oder Rißbildungen noch solche durch das Vorhandensein von Fremdmaterialien in den Stoßflächen auf. Auch ist die Ausbildung entsprechender Herzstückbereiche kostengünstiger.The teachings according to the invention ensure in a simple manner that a relative movement perpendicular to the longitudinal axis cannot occur between the rail parts to be connected without welding being necessary in this connection area, in particular in the frog area penetrated by the connection element. As a result, there are no problems with edge decarburization or cracking, or problems due to the presence of foreign materials in the abutting surfaces. The formation of corresponding core areas is also more cost-effective.
Unversch weißt bedeutet in diesem Fall, daß im Verbindungsbereich zwischen Flügelschienen und Herzstück, also in dem Bereich, wo diese Elemente über die Futterstücke mittels eines Verbindungselementes verbunden sind, die Herzstück¬ abschnitte nicht untereinander verschweißt sind. Dies schließt jedoch nicht aus, daß zungenseitig die Spitze oder weichenendenseitig die Regelschienen angeschweißt sind.In this case, unshielded means that in the connection area between wing rails and frog, that is to say in the area where these elements are connected via the lining pieces by means of a connection element, the frog sections are not welded to one another. However, this does not exclude that the tip is welded on the tongue side or the control rails are welded on the switch end.
Bei der Verwendung der spielfrei angeordneten Hülse, durch die eine Relativbewe¬ gung in jeder Richtung ausgeschlossen ist, kann diese in den Gleisteilen bzw. Futterstücken eingepreßt oder eingeschrumpft sein.When using the sleeve, which is arranged without play and by means of which a relative movement in any direction is excluded, it can be pressed or shrunk in the track parts or lining pieces.
So besteht die Möglichkeit, daß die Herzstückabschnitte und Futterstücke erwärmt werden, um sodann die Hülse einzubringen. Nach dem Abkühlen ist die Hülse eingepreßt, so daß die gewünschte Spielfreiheit sichergestellt ist.So there is the possibility that the frog sections and chucks are heated to then insert the sleeve. After cooling, the sleeve is pressed in, so that the desired freedom from play is ensured.
Alternativ besteht z. B. auch die Möglichkeit, die Hülse zu unterkühlen, um diese sodann in die zugeordneten Ausnehmungen von Herzstückabschnitten und Futterstücken einzubringen. Auch besteht die Möglichkeit, daß die Hülse in die Herzstückabschnitte unterkühlt eingebracht wird und daß nach deren spielfreier Verbindung anschließend auf die Hülse zwar erwärmte Futtterstücke aufgeschrumpft werden.Alternatively, there is e.g. B. also the possibility of subcooling the sleeve so that it can then be introduced into the associated recesses of frog sections and chucks. There is also the possibility that the sleeve is introduced undercooled in the frog sections and that, after their play-free connection, heated chuck pieces are then shrunk onto the sleeve.
Eine eigenerfinderische Weiterbildung eines Gleisabschnittes in Form eines Herzstückbereichs, wobei die Flügelschienen jeweils einen Flügelschienenkopf mit dem Herzstück zugewandten Leitflächen für ein den Herzstückbereich durch¬ fahrendes Rad aufweisen, zeichnet sich dadurch aus, daß die jeweilige Leitfläche der Flügelschienen eine Krümmung aufweist, die auf die Krümmung eines das Herzstück durchfahrenden Rades abgestimmt ist. Dabei kann in bezug auf die jeweilige Kontaktfläche zwischen Rad und Leitfläche eine konstante Krümmungs¬ differenz oder eine sich stetig ändernde Krümmungsdifferenz betrachtet in einer Ebene senkrecht zur Längsrichtung der Gleisteile bestehen.A proprietary further development of a track section in the form of a frog area, the wing rails each having a wing rail head with the frog facing guide surfaces for a wheel passing through the frog area, is characterized in that the respective guiding surface of the wing rails has a curvature that points to the curvature of a wheel passing through the heart is tuned. With regard to the respective contact surface between the wheel and the guide surface, there can be a constant curvature difference or a constantly changing curvature difference, viewed in a plane perpendicular to the longitudinal direction of the track parts.
Die in ihrer Form bekannten barren- oder Futterstücke setzen sich vorzugsweise aus einem von dem Herzstück ausgehenden und von der Hülse vorzugsweise vollständig spielfrei durchsetzten quaderförmigen, inneren Abschnitt, einen sich in R ichtung der Flügelschienen erweiternden ersten keilförmigen, im Schnitt trapezförmigen Abschnitt und einen unterhalb des Flügelschienenkopfs und diesen abstützenden zweiten keilförmigen und ebenfalls im Schnitt trapezförmigen Abschnitt zusammen. Dabei kann der erste keilförmige Abschnitt flügelschienen- kopfseitig eine Außenfläche aufweisen, die stetig in die Leitfläche übergeht. Insbesondere kann die diesbezügliche Außenfläche des ersten keilförmigen Abschnitts eine Krümmung aufweisen, die das Verhalten der Leitfläche zeigt.The bar or known in their form Lining pieces are preferably composed of a cuboid-shaped inner section extending from the centerpiece and preferably completely free of play through the sleeve, a first wedge-shaped section widening in the direction of the wing rails, a trapezoidal section in section, and a second wedge-shaped section below and supporting the wing rail head and likewise in the section trapezoidal section together. The first wedge-shaped section on the wing rail head side can have an outer surface that continuously merges into the guide surface. In particular, the relevant outer surface of the first wedge-shaped section can have a curvature that shows the behavior of the guide surface.
Weitere Einzelheiten, Vorteile und Merkmale der Erfindung ergeben sich nicht nur aus den Ansprüchen, den diesen zu entnehmenden Merkmalen -für sich und/oder in Kombination-, sondern auch aus der nachfolgenden Beschreibung eines der Zeichnung zu entnehmenden bevorzugten Ausführungsbeispiels.Further details, advantages and features of the invention result not only from the claims, the features to be extracted from them - individually and / or in combination - but also from the following description of a preferred exemplary embodiment which can be seen from the drawing.
Es zeigen: Fig. 1 einen Schnitt durch ein erstes Ausführungsbeispiel eines Herz¬ stückbereichs,Show it: 1 shows a section through a first embodiment of a frog area,

Fig. 3 einen weiteren Schnitt durch das Herzstück gemäß dem zweiten Ausführungsbeispiel nach Fig. 2.3 shows a further section through the centerpiece according to the second exemplary embodiment according to FIG. 2.
In der Fig. 1 ist ein Schnitt durch einen Herzstückbereich wiedergegeben, der aus einem aus zwei Schienenabschnitten (12) und (14) bestehenden Herzstück (16) und entlang diesem verlaufenden Flügelschienen (18) und (20) besteht. Die Schienen¬ abschnitte (12) und (14) können aus Vollschienen hergestellt sein.1 shows a section through a frog area, which consists of a frog (16) consisting of two rail sections (12) and (14) and wing rails (18) and (20) running along this. The rail sections (12) and (14) can be made from solid rails.
Zur Beabstandung von den Flügelschienen (18) und (20) zu dem Herzstück (16), also zu den zugewandten Schienenabschnitten (12) und (14) sind Futterstücke (22) und (24) grundsätzlich bekannter Geometrie vorgesehen.For spacing from the wing rails (18) and (20) to the centerpiece (16), that is to say to the facing rail sections (12) and (14), lining pieces (22) and (24) of generally known geometry are provided.
Die Verbindung zwischen den Flügelschiene (18) und (20) und den Futterstücken (22) und (24) sowie zwischen den Futterstücken (22) und (24) und den Gleis¬ abschnitten (12) und (14) und deren Verbindung untereinander selbst erfolgt schweißlos, ohne daß jedoch eine Relativbewegung zwischen diesen möglich ist. Dies wird dadurch erreicht, daß zur Erzielung einer kraftschlüssigen bzw. teilweise fonnschlüssigen Verbindung ein Verbindungselement wie Bolzen (26) die zuvor beschriebene Einheit durchsetzt, wobei die Futterstücke (22) und (24) teilweise, die Schienenabschnitte (12) und ( 14) des Herzstücks (16) vollständig von einer Hülse (28) spielfrei durchsetzt sind, innerhalb der sich der Bolzen (26) erstreckt. Der Bolzen wird über Zwischenstücke (30) und (32) an den äußeren Stegflächen der Flügelschienen (18) und (20) festgezogen, um so die gewünschte kraftεchiüssige Verbindung zwischen den Flügelschienen (18), den Futterstücken (22) und (24) und dem Herzstück (16) sicherzustellen. Dadurch, daß die Hülse (28) die Gleisabschnitte (12) und (14) und zumindest bereichsweise die Futterstücke (22) und (24) spielfrei durchsetzt, ist eine Relativbewegung zwischen diesen und damit zu den Flügelschienen (18) und (20) ausgeschlossen. Letzteres wird durch die Futterstücke (22) und (24) bewirkt, die jeweils einen äußeren keilförmigen, im Schnitt trapezförmigen Abschnitt (34) bzw. (36) aufweisen, der derart an die Geometrie der nicht näher bezeichneten Laschenkammer der zugeordneten Flügelschienen (18) bzw. (20) angepaßt ist, so daß eine Relativbewegung ausgeschlossen ist.The connection between the wing rail (18) and (20) and the lining pieces (22) and (24) and between the lining pieces (22) and (24) and the track sections (12) and (14) and their connection to one another itself takes place without welding, but without a relative movement between them being possible. This is achieved in that a connecting element such as bolts (26) passes through the unit described above in order to achieve a non-positive or partially positive connection, the lining pieces (22) and (24) partially, the rail sections (12) and (14) of the Heart (16) are completely penetrated by a sleeve (28) without play, within which the bolt (26) extends. The bolt is tightened via intermediate pieces (30) and (32) on the outer web surfaces of the wing rails (18) and (20) in order to achieve the desired force-locking connection between the wing rails (18), the lining pieces (22) and (24) and the centerpiece (16). Due to the fact that the sleeve (28) passes through the track sections (12) and (14) and at least in some areas the lining pieces (22) and (24) without play, a relative movement between these and thus to the wing rails (18) and (20) is excluded . The latter is brought about by the lining pieces (22) and (24), each of which has an outer wedge-shaped section (34) or (36) which is trapezoidal in section, and which thus conforms to the geometry of the lug chamber of the associated wing rails (18), which is not described in more detail. or (20) is adapted so that a relative movement is excluded.
Die Futterstücke (22) und (24) setzen sich jeweils aus einem inneren quaderförmi- gen und an den äußeren Stegflächen der Schienenabschnitte (12) und (14) sich abstützenden inneren Abschnitte (38) bzw. (40), einem sich anschließenden in Richtung der Flügelschienenköpfe (42) bzw. (44) sich erstreckenden ersten keilförmigen Abschnitt (46) bzw. (48) sowie dem an die Laschen der Flügelschienen (18) und (20) angepaßten und in einer gemeinsamen Ebene (35) bzw. (37) die Flügelschienenköpfe (42) und (44) abstützenden zweiten keilförmigen Abschnitt (34) bzw. (36) zusammen.The lining pieces (22) and (24) each consist of an inner cuboid-shaped inner sections (38) and (40), which are supported on the outer web surfaces of the rail sections (12) and (14), and a subsequent one in the direction of the wing rail heads (42) or (44) extending first wedge-shaped section (46) or (48) and that adapted to the tabs of the wing rails (18) and (20) and in a common plane (35) or (37 ) together the wing rail heads (42) and (44) supporting the second wedge-shaped section (34) and (36).
Innerhalb der quaderförmigen Abschnitte (38) und (40) verläuft die Hülse (28) spielfrei.The sleeve (28) runs without play within the cuboid sections (38) and (40).
Als besonderes Merkmal ist noch hervorzuheben, daß die Flügelschienenköpfe (42) und (44) Leitflächen (50) und (52) mit jeweils einer Krümmung aufweisen, die der das Herzstück durchfahrender Räder (54) angepaßt ist. Dabei kann in der Berührungsfläche zwischen der Leitfläche (50) und (52) und dem Rad (54) eine konstante Krümmungsdifferenz oder auf einanderfolgenden Abschnitten eine sich stetig ändernde Krümmungsdifferenz bestehen, betrachtet jeweils in einer Ebene senkrecht zur Herzstücklängsachse. Auf die Leitfiächen (50) und (52) abgestimmt erstrecken sich die zugewandten Außenflächen (56) und (58) der inneren keilförmi¬ gen, im Schnitt trapezförmigen Abschnitte (46) und (48). Dadurch, daß die Flügelschienenkδpfe (42) und (44) unterseitig von den zweiten keilförmigen Abschnitten (34) und (36) weitgehend über ihre ganze Breite in der gemeinsamen Ebene (35) und (37) abgestützt sind, ergibt sich im Vergleich zum vorbekannten Stand der Technik eine größere Auflagefläche, wodurch wiederum die Stabilität des Herzstückbereichs erhöht wird.As a special feature, it should also be emphasized that the wing rail heads (42) and (44) have guide surfaces (50) and (52) each with a curvature which is adapted to the wheels (54) passing through the heart. There may be a constant curvature difference in the contact surface between the guide surface (50) and (52) and the wheel (54), or a continuously changing curvature difference on successive sections, viewed in each case in a plane perpendicular to the longitudinal axis of the frog. The facing outer surfaces (56) and (58) of the inner wedge-shaped sections (46) and (48), which are trapezoidal in section, extend in coordination with the guide surfaces (50) and (52). The fact that the wing rail heads (42) and (44) are supported on the underside of the second wedge-shaped sections (34) and (36) largely over their entire width in the common plane (35) and (37), results in comparison to the previously known State of the art a larger contact surface, which in turn increases the stability of the frog area.
Die verwendeten Materialien der Schienenabschnitte (12) und (14), der Futter¬ stücke (22) und (24) sowie der Hülse (28) sollten gleiche oder nahezu gleiche Ausdehnungskoeffizienten aufweisen.The materials used for the rail sections (12) and (14), the lining pieces (22) and (24) and the sleeve (28) should have the same or almost the same expansion coefficient.
In den Fig. 2 und 3 ist eine weitere Ausführungsfonn eines Herzstücksbereichs dargestellt, bei dem das Herzstück (60), das den Flügelschienen (62) und (64) zugeordnet ist, aus zwei nicht miteinander verschweißten Schienenabschnitten (66) und (68) besteht, die vorzugsweise aus Vollschienen hergestellt sind.2 and 3 show a further embodiment of a frog area, in which the frog (60), which is assigned to the wing rails (62) and (64), consists of two rail sections (66) and (68) which are not welded to one another , which are preferably made of solid rails.
Zwischen den Flügelschienen (62) bzw. (64) und dem Herzstück (60) sind entsprechend der Fig. 1 Futterstücke (70) und (72) angeordnet. Die so gebildete Einheit aus Flügelschienen (62) und (64), Futterstücken (70) und (72) sowie Herzstück (60) wird mit Spiel von einem Bolzen (74) durchsetzt, der außenseitig über Zwischenstücke (76) und (78) an den äußeren Stegflächen der Flügelschienen (62) und (64) festziehbar ist. um den gewünschten Kraftschluß zu bewirken.Between the wing rails (62) and (64) and the heart (60) lining pieces (70) and (72) are arranged according to FIG. 1. The unit thus formed from wing rails (62) and (64), lining pieces (70) and (72) and heart (60) is interspersed with play by a bolt (74), which is on the outside via intermediate pieces (76) and (78) the outer web surfaces of the wing rails (62) and (64) can be tightened. to bring about the desired adhesion.
Um auszuschließen, daß sich die das Herzstück bildende Teile, insbesondere die Schienenabschnitte (66) und (68) des Herzstücks (60) in Richtung der Mittelachse (80) relativ zueinander bewegen können, sind die aufeinanderliegenden Flächen der Schienenabschnitte (66) und (68) bzw. der an diesen anliegenden Flächen der Futterstücke (70) und (72) profiliert. Diese Profilierung wird durch von den aufein¬ anderliegenden Flächen ausgehende und in Längsrichtung des Herzstücks verlaufende Zähne gebildet, von denen beispielhaft in jeder Fläche jeweils nur ein Zahn mit dem Bezugszeichen (82), (84), (86), (88), (90) und (92) versehen ist. Dabei sind die jeweiligen Zähne derart ausgebildet, daß Zahnflanken von ineinandergreifenden Zähnen spielfrei zueinander ausgerichtet sind, wohingegen zugeordneter Zahnkopf (81 ) und Zahnfuß (83) von von gegenüberliegenden Flächen ausgehenden Zähnen zueinander beabstandet sind (siehe auch vergrößerten Ausschnitt in Fig. 3).In order to rule out that the parts forming the frog, in particular the rail sections (66) and (68) of the frog (60) can move relative to one another in the direction of the central axis (80), the superimposed surfaces of the rail sections (66) and (68 ) or the surfaces of the lining pieces (70) and (72) which are in contact with them. This profiling is formed by teeth extending from the superimposed surfaces and extending in the longitudinal direction of the frog, of which, for example, only one tooth in each surface with the reference numerals (82), (84), (86), (88), ( 90) and (92) is provided. The respective teeth are designed such that tooth flanks of interlocking teeth are aligned with each other without play, whereas the associated tooth head (81) and tooth base (83) are spaced from one another by teeth emanating from opposite surfaces (see also enlarged detail in FIG. 3).
Des weiteren beschreiben die Flanken, von denen beispielhaft zwei aufein- anderliegende mit den Bezugszeichen (94) und (96) versehen sind, zur Mittelachse (80) einen Winkel α, der vorzugsweise zwischen 65 " und 75 ', insbesondere bei 70 * liegt.Furthermore, the flanks, two of which, for example, are provided with the reference numerals (94) and (96), describe an angle α with the central axis (80), which is preferably between 65 "and 75 ', in particular at 70 * .
Auf diese Weise ist beim Anziehen des Bolzens (74) der gewünschte For schluß erzielbar, so daß eine Relativbewegung in Richtung der Mittelachse (80) ausge¬ schlossen ist. Entsprechende Geometrien gelten selbstverständlich auch für die zwischen den Futterstücken (70) bzw. (72) und dem Herzstück (60) verlaufenden Zähne (82), (84) bzw. (90). (92).In this way, the desired closing can be achieved when the bolt (74) is tightened, so that a relative movement in the direction of the central axis (80) is excluded. Corresponding geometries naturally also apply to the teeth (82), (84) or (90) running between the chuck pieces (70) or (72) and the heart piece (60). (92).
Hinsichtlich der Schienenköpfe der Flügelschienen (62) und (64) bzw. der Ausbildung der Leitflächen sowie der auf diese ausgerichteten Geometrie der Futterstücke (70) und (72) wird auf das Ausführungsbespiel der Fig. 1 verwiesen, so daß es eine eiteren Erläuterung nicht bedarf.With regard to the rail heads of the wing rails (62) and (64) or the formation of the guide surfaces and the geometry of the lining pieces (70) and (72) aligned with this, reference is made to the exemplary embodiment of FIG. 1, so that there is no further explanation requirement.
Zu erwähnen ist jedoch noch, da ß die gemeinsamen Ebenen von Futterstück (70) bzw. (72) und Flügelschienenkopfunterseite, die mit dem Bezugszeichen (98) bzw. ( 100) versehen ist, zur Mittelachse (80) einen Winkel ß beschreiben, der gleichfalls vorzug _s--'w * *eilsjeυ zwischen 65 ° und 75 ', insbesondere bei 70 ' liegt.However, it should also be mentioned that ß the common planes of chuck (70) or (72) and wing rail head underside, which is provided with the reference symbol (98) or (100), describe an angle ß to the central axis (80) which also preferred _s-- ' w * * ei l s j e υ is between 65 ° and 75', especially at 70 '.
Auch ist anzumerken, daß die Hülse in Fig. 2 und 3 kein zwingendes Element ist. It should also be noted that the sleeve in FIGS. 2 and 3 is not a mandatory element.
