Abstract

Articulated butt joint for suspended rails of a monorail suspended railway, wherein the connection between the lower flanges is deformable as to be horizontal and vertical transverse forces and wherein the connection between the upper flanges absorbs the horizontal and vertical transverse forces. The aim of the present invention is to provide a butt joint which is more appropriate to withstand the transverse forces generated by the vehicle weight and to further reduce to the minimum the inevitable impact forces upon overrunning the expansion gap, as well as their negative consequences. To this effect, the present invention proposes that the linking elements (5) between the upper flanges be comprised of suspension metal plates (10) secured to the upper flanges, overlapping each other in the longitudinal direction of the rails and provided in the overlapping area with longitudinal holes (11) covering each other and tapered as an arc of a circle and intended to receive a suspension bolt (12), the medial point (13) being located in the middle of the expansion gap and at the height of the rolling surfaces on the upper side of the lower flange.

Description

Die Erfindung betrifft eine gelenkige Stoßverbindung für aufhängbare Schienen von Einschienenhängebahnen mit auf den Unterflanschen laufenden Fahrzeugrädern, bei welcher zwischen den Oberflanschen Verbindungsmittel vorgesehen sind, die zur Aufhängung der Schienen im Bereich des Schienenstoßes dienen und derart kreisbogenförmig aneinander geführt sind, daß sie eine Verschwenkung der Schienen in der vertikalen Längsmittenebene um ein Gelenk im Bereich der Unterflansche zulassen und vertikale und horizontale Querkräfte von einem Schienenende auf das andere übertragen, wobei das Gelenk im Bereich der Unterflansche in Schienenlängsrichtung zugfest, gegen vertikale und horizontale Querkräfte jedoch nachgiebig ausgebildet ist.The invention relates to an articulated butt joint for hanging rails of monorails with vehicle wheels running on the lower flanges, in which connecting means are provided between the upper flanges, which are used to suspend the rails in the region of the rail joint and are guided in a circular arc so that they pivot the rails allow in the vertical longitudinal center plane around a joint in the area of the lower flanges and transfer vertical and horizontal transverse forces from one rail end to the other, whereby the joint in the area of the lower flanges is tensile in the longitudinal direction of the rail, but is flexible against vertical and horizontal transverse forces.

Bei einer nach dem Stande der Technik (DE-C-24 19062) bekannten Stoßverbindung der genannten Art bestehen die Verbindungsmittel im Bereich der Oberflansche aus einem dem einen Schienenende zugeordneten kreisbogenförmigen Zapfen, der in eine dem anderen Schienenende zugeordnete Führungsöse eingreift, die zugleich mit einem Aufhängehaken für die Aufhängung der Schienen im Bereich des Schienenstoßes versehen ist. Der Mittelpunkt des Kreisbogens liegt unterhalb des Unterflansches in der Höhe des dort befindlichen, die Unterflansche verbindenden Gelenkes. Dieses Gelenk zwischen den Unterflanschen weist einen in Schienenlängsrichtung verlaufenden zugfesten Schraubenbolzen auf, der mit horizontalem und vertikalem Spiel an den benachbarten Unterflanschen zugeordneten Befestigungselementen angreift und von einem zwischen beiden Schienen angeordneten, vorgespannten elastischen Füllstück unter Zugspannung gehalten wird.In a butt joint of the type mentioned in the prior art (DE-C-24 19062), the connecting means in the region of the upper flanges consist of an arc-shaped pin assigned to one rail end, which engages in a guide eye assigned to the other rail end, which at the same time engages with a Suspension hook is provided for the suspension of the rails in the area of the rail joint. The center of the circular arc lies below the lower flange at the level of the joint located there that connects the lower flanges. This joint between the lower flanges has a tensile screw bolt running in the longitudinal direction of the rail, which engages with horizontal and vertical play on the fastening elements associated with the adjacent lower flanges and is held under tension by a prestressed elastic filler arranged between the two rails.

Diese nach dem Stande der Technik vorbekannte Stoßverbindung hat den Vorteil, daß im Bereich der Lücke zwischen den Unterflanschen nur geringe Stoßbelastungen auftreten, weil das zwischen den Schienen befindliche elastische Füllstück die unvermeidlich auftretenden Stöße dämpft. Die gegen Querkräfte nachgiebige Ausbildung der Verbindung zwischen den Unterflanschen hat den Vorteil, daß ein Verschleiß durch Querkräfte im Bereich der Unterflanschverbindung nicht auftreten kann, setzt aber voraus, daß die Verbindung im Bereich der Oberflansche so ausgebildet ist, daß sie alle Querkräfte, insbesondere die durch das Gewicht der Fahrzeuge verursachten vertikalen Querkräfte, aufzunehmen vermag.This prior art butt joint has the advantage that only slight impact loads occur in the area of the gap between the lower flanges because the elastic filler located between the rails dampens the inevitable impacts. The formation of the connection between the lower flanges, which is flexible against lateral forces, has the advantage that wear due to lateral forces in the area of the lower flange connection cannot occur, but assumes that the connection in the area of the upper flanges is designed in such a way that it absorbs all lateral forces, particularly those caused by the weight of the vehicles caused vertical shear forces.

Beim Betrieb von Einschienenhängebahnen geht man in der neuesten Zeit fortschreitend von seilgezogenen Zugeinheiten über zu selbstfahrenden Zugeinheiten mit Hängebahnlokomotive. Dies führt zu erheblich gesteigerten Fahrzeuggewichten und zu einer andersartigen Belastung der Schienenverbindung, weil neben dem Fahrzeuggewicht auch noch die Zugkräfte abgestützt werden müssen, die sonst von dem Zugseil aufgenommen werden. Für die Aufnahme der Zugkräfte ist die Schienenverbindung gemäß dem Gattungsbegriff aufgrund der besonderen Konstruktion der Verbindungsmittel im Bereich der Unterflansche besonders gut geeignet, weil sie aufgrund des vorgespannten elastischen Zwischenstückes weitestgehend spielfrei bleibt, so daß es praktisch zu keinem Verschleiß kommt. Wegen der gesteigerten Fahrzeuggewichte treten allerdings Schwierigkeiten im Bereich der Verbindungsmittel zwischen den Oberflanschen auf. Dadurch, daß die Aufhängung im Bereich der Stoßverbindung nur an einem der aneinanderstoßenden Schienenenden erfolgt, muß der gebogene Führungszapfen allein die gesamten durch das Fahrzeuggewicht verursachten Querkräfte übertragen. Hinzu kommt, daß die beim Überfahren der Stoßlücke unvermeidbar auftretenden Stoßkräfte über einen verhältnismäßig langen Hebelarm auf den gebogenen Führungszapfen und dessen Führung einwirken. Haben sich der gebogene Führungszapfen und/oder dessen Führung aufgrund dieser Belastungen erst einmal - wenn auch nur geringfügig - verformt, schreitet der weitere Verschleiß schnell fort, weil es dann aufgrund des Höhenversatzes der Laufflächen der Unterflansche zu fortschreitend stärkeren Stoßbelastungen kommt.The operation of monorail monorails is progressively progressing from cable-drawn train units to self-propelled train units with monorail locomotives. This leads to considerably increased vehicle weights and to a different type of load on the rail connection, because in addition to the vehicle weight, the tensile forces that would otherwise be absorbed by the pull rope must also be supported. For the absorption of tensile forces, the rail connection according to the generic term is particularly well suited due to the special construction of the connecting means in the area of the lower flanges, because it remains largely free of play due to the prestressed elastic intermediate piece, so that there is practically no wear. Because of the increased vehicle weights, however, difficulties arise in the area of the connecting means between the upper flanges. Because the suspension in the area of the butt joint only takes place on one of the abutting rail ends, the curved guide pin alone has to transmit the entire transverse forces caused by the vehicle weight. In addition, the impact forces that unavoidably occur when crossing the impact gap act on the curved guide pin and its guide via a relatively long lever arm. Once the curved guide pin and / or its guide has deformed - even if only slightly - as a result of these loads, further wear progresses quickly, because then there is progressively greater shock loads due to the height offset of the running surfaces of the lower flanges.

Nach dem Stande der Technik (DE-B-25 08 739) ist weiterhin eine gelenkige Stoßverbindung für aufhängbare Schienen von Einschienenhängebahnen bekannt, bei der unterhalb der Unterflansche ein die Querkräfte aufnehmendes Bolzengelenk mit quer zur Schienenlängsrichtung verlaufendem Gelenkbolzen und zwischen den Oberflanschen einander in Schienenlängsrichtung überlappende Aufhängebleche vorgesehen sind, die im Überlappungsbereich mit in Schienenlängsrichtung aufgeweiteten Langlöchern versehen sind, die zur Aufnahme eines Aufhängebolzens dienen. Die derart ausgebildete Verbindung zwischen den Oberflanschen hat jedoch den Nachteil, daß sie nur in Kombination mit die Querkräfte aufnehmenden Verbindungsmitteln zwischen den Unterflanschen verwendet werden kann. Anderenfalls besteht die Gefahr, daß es bei einer Abwinkelung einer der Schienen in vertikaler Längsebene zu einem Höhenversatz zwischen den aneinanderstoßenden Schienen kommt.According to the state of the art (DE-B-25 08 739) an articulated butt joint for suspension rails of monorails is also known, in which below the lower flanges a transverse joint absorbing the transverse forces with a joint bolt extending transversely to the longitudinal direction of the rail and overlapping one another in the longitudinal direction of the rail between the upper flanges Suspension plates are provided, which are provided in the overlap area with elongated holes widened in the longitudinal direction of the rail, which serve to receive a suspension bolt. However, the connection between the upper flanges designed in this way has the disadvantage that it can only be used in combination with connecting means which absorb the transverse forces between the lower flanges. Otherwise there is a risk that if one of the rails bends in the vertical longitudinal plane, there will be a height offset between the abutting rails.

Es ist Aufgabe der Erfindung, die Stoßverbindung gemäß dem Gattungsbegriff des Patentanspruches 1 dahingehend weiterzubilden, daß sie besser dazu geeignet ist, die durch das Fahrzeuggewicht verursachten Querkräfte zu übertragen, und außerdem die unvermeidlichen Stoßkräfte beim Überfahren der Stoßlücke und deren schädliche Auswirkungen auf ein Minimum reduziert. Zur Lösung dieser Aufgabe schlägt die Erfindung ausgehend von einer gelenkigen Stoßverbindung gemäß dem Gattungsbegriff des Patentanspruches 1 vor, daß die Verbindungsmittel zwischen den Oberflanschen aus auf den Oberflanschen befestigten Aufhängeblechen bestehen, die sich in Schienenlängsrichtung überlappen und im Überlappungsbereich mit sich deckenden kreisbogenförmig aufgeweiteten Langlöchern versehen sind, die zur Aufnahme eines Aufhängebolzens dienen, wobei der Mittelpunkt der beiden Kreisbögen in der Mitte der Stoßlücke und in der Höhe der Laufflächen auf der Oberseite der Unterflansche der Schienen liegt.It is an object of the invention to develop the butt joint according to the preamble of claim 1 in such a way that it is better suited to transmitting the lateral forces caused by the vehicle weight, and also reduces the inevitable impact forces when crossing the gap and their harmful effects to a minimum . To achieve this object, the invention proposes, starting from an articulated butt joint according to the preamble of claim 1, that the connecting means between the upper flanges consist of hanging plates attached to the upper flanges, which overlap in the longitudinal direction of the rail and are provided with overlapping, elongated, arc-shaped elongated holes in the overlap region , which are used to hold a suspension bolt, with the center of the two arcs in the middle of the gap and at the height of the treads on the top of the lower flanges of the rails.

Die Stoßverbindung gemäß der Erfindung hat zunächst den Vorteil, daß beide Aufhängelaschen direkt mit dem Aufhängebolzen verbunden sind, so daß die durch das Fahrzeuggewicht verursachten Querkräfte nicht von einem Schienenende auf das andere übertragen zu werden brauchen. Diese Querkräfte werden vielmehr von jedem Schienenende aus über die zugehörigen Aufhängebleche direkt in den Aufhängebolzen eingeleitet. Weiterhin hat die Anordnung der Mittelpunkte der Kreisbögen der Langlöcher in der Mitte der Stoßlücke und in der Höhe der Laufflächen an der Oberseite der Unterflansche den Vorteil, daß die von den Fahrzeugrädern zu überfahrende Stoßlücke bei allen möglichen Winkelstellungen der Schiene in der vertikalen Schwenkebene minimal schmal bleibt und daß die von den Lochleibungen der beiden Langlöcher erzeugten Reaktionskräfte auf die Mitte der Stoßlücke in der Höhe der Laufflächen gerichtet sind, d. h. genau auf den Punkt, von dem die beim Überfahren der Stoßlücke erzeugten Stoßkräfte ausgehen. Infolgedessen erzeugen die beim Überfahren der Stoßlücke unvermeidlich auftretenden Stoßkräfte praktisch keine zusätzlichen Zug- oder Druckspannungen, die von der Verbindung zwischen den Unterflanschen aufgenommen werden müßten. Weitere Vorteile der Stoßverbindung gemäß der Erfindung liegen in dem erkennbar robusten und einfachen Aufbau sowie in der besonders einfachen Fertigung, weil es bei der Fertigung im wesentlichen nur auf die Maßhaltigkeit der kreisbogenförmigen Langlöcher im Bezug auf die Oberseite der Unterflansche ankommt, im übrigen aber erhebliche Fertigungstoleranzen zugelassen werden können.The butt joint according to the invention initially has the advantage that both suspension brackets are connected directly to the suspension bolt, so that the transverse forces caused by the vehicle weight do not need to be transmitted from one rail end to the other. Rather, these transverse forces are introduced from each rail end directly into the suspension bolts via the associated suspension plates. Furthermore, the arrangement of the centers of the arcs of the elongated holes in the middle of the butt gap and in the height of the treads on the top of the lower flanges has the advantage that the butt gap to be traveled over by the vehicle wheels remains minimally narrow in all possible angular positions of the rail in the vertical swivel plane and that the reaction forces generated by the embrasures of the two elongated holes are directed towards the center of the gap at the level of the treads, d. H. exactly to the point from which the impact forces generated when crossing the impact gap originate. As a result, the impact forces which inevitably occur when the impact gap is passed over produce practically no additional tensile or compressive stresses which would have to be absorbed by the connection between the lower flanges. Further advantages of the butt joint according to the invention lie in the recognizable robust and simple construction and in the particularly simple manufacture, because the only important thing in the manufacture is the dimensional accuracy of the circular-shaped elongated holes in relation to the upper side of the lower flanges, but also considerable manufacturing tolerances can be approved.

Eine besonders bevorzugte Ausführungsform der Stoßverbindung gemäß der Erfindung sieht vor, daß die Aufhängebleche an einem Ende der Schiene auf der einen Seite der vertikalen Längsmittenebene der Schiene und am anderen Ende auf der gegenüberliegenden Seite der vertikalen Längsmittenebene der Schiene angeordnet sind. Auf diese Weise erhalten die Schienen an beiden Schienenenden eine völlig identische Ausgestaltung um 180° seitenverkehrt, so daß die Schienen beim Einbau nicht gewendet zu werden brauchen, gleichgültig wie sie antransportiert worden sind. Dies ist insbesondere in engen Bergbaustrecken von großer Wichtigkeit. Ein weiterer Vorteil dieser Ausgestaltung liegt darin, daß jede Einzelschiene aus dem verspannten Schienenstrang seitlich ausgebaut und ausgewechselt werden kann.A particularly preferred embodiment of the butt joint according to the invention provides that the suspension plates are arranged at one end of the rail on one side of the vertical longitudinal center plane of the rail and at the other end on the opposite side of the vertical longitudinal center plane of the rail. In this way, the rails at both ends of the rails have a completely identical configuration reversed by 180 °, so that the rails do not have to be turned over during installation, regardless of how they were transported. This is of great importance especially in narrow mining routes. Another advantage of this embodiment is that each individual rail can be laterally removed and replaced from the tensioned rail track.

Der Aufhängebolzen wird zweckmäßig von einem Schäkel getragen, der die beiden Aufhängebleche umgreift. Auf diese Weise erfahren die beiden Aufhängebleche auf besonders einfache Weise eine seitliche Führung gegen horizontale Querkräfte. Gegen solche horizontalen Querkräfte können auch allerdings andere geeignete Führungsmittel vorgesehen werden.The hanging bolt is conveniently carried by a shackle that encompasses the two hanging plates. In this way, the two suspension plates are guided in a particularly simple manner against lateral transverse forces. Against such horizontal transverse forces, however, other suitable guide means can also be provided.

Um die spezifische Flächenpressung zwischen dem Aufhängebolzen und den Lochleibungen der Langlöcher möglichst gering zu halten, ist weiterhin vorgesehen, daß der Aufhängebolzen an seiner nach oben weisenden Seite abgeflacht ausgebildet ist, wobei die Abflachung dem Kurvenradius der Lochleibung der Langlöcher angepaßt ist. Auf diese Weise verteilen sich die Aufhängekräfte auf eine verhältnismäßig große Fläche, so daß auch bei großen Lasten Verformungen an der Oberfläche des Bolzens und/oder an den Lochleibungen der Langlöcher nicht zu befürchten sind.In order to keep the specific surface pressure between the suspension bolt and the embrasures of the elongated holes as low as possible, it is further provided that the suspension bolt is flattened on its upward-facing side, the flattening being adapted to the curve radius of the embrasure of the elongated holes. In this way, the suspension forces are distributed over a relatively large area, so that deformations on the surface of the bolt and / or on the perforations of the elongated holes are not to be feared, even with large loads.

Ein Ausführungsbeispiel der Erfindung wird im folgenden anhand der Zeichnung näher erläutert.An embodiment of the invention is explained below with reference to the drawing.

  • Fig. 3 is a plan view of a rail section.

In der Zeichnung sind die aneinanderstoßenden Schienenabschnitte mit den Bezugszeichen 1 und 2 bezeichnet. Bei den Schienen handelt es sich um I-Träger, deren Steg vertikal angeordnet ist, so daß die nach oben weisenden Flächen der Unterflansche die Laufflächen 3 für die Fahrzeugräder der Einschienenhängebahn bilden. Die Stoßverbindung besteht aus einem im Bereich der Unterflansche angeordneten Gelenk, welches in seiner Gesamtheit mit dem Bezugszeichen 4 bezeichnet ist, und den im Bereich der Oberflansche angeordneten Verbindungsmitteln, die in ihrer Gesamtheit mit dem Bezugszeichen S bezeichnet sind.In the drawing, the abutting rail sections are designated by the reference numerals 1 and 2. The rails are I-beams, the web of which is arranged vertically, so that the upward-facing surfaces of the lower flanges form the running surfaces 3 for the vehicle wheels of the monorail overhead conveyor. The butt joint consists of a joint arranged in the area of the lower flanges, which is designated in its entirety by reference number 4, and the connecting means arranged in the area of the upper flanges, which are referred to in their entirety by reference number S.

Das Gelenk im Bereich der Unterflansche weist zwei Befestigungsblöcke 6 auf, die unter die Unterflansche der Schienenabschnitte 1 bzw. 2 geschweißt sind. In jedem Befestigungsblock 6 befindet sich eine in Schienenlängsrichtung verlaufende Bohrung, durch welche ein in Schienenlängsrichtung verlaufender Schraubenbolzen 7 durchgesteckt ist. Zwischen dem Schraubenbolzen 7 und den Bohrungen in den Befestigungsblöcken 6 ist sowohl in horizontaler als auch in vertikaler Richtung das für die Abwinkelung der Schienenabschnitte 1The joint in the area of the lower flanges has two fastening blocks 6, which are welded under the lower flanges of the rail sections 1 and 2, respectively. In each fastening block 6 there is a bore running in the longitudinal direction of the rail through which a screw bolt 7 extending in the longitudinal direction of the rail is inserted. Between the screw bolt 7 and the bores in the mounting blocks 6 is that for the bending of the rail sections 1 in both the horizontal and vertical directions

und 2 erforderliche Spiel vorhanden. Zwischen den Befestigungsblöcken 6 ist ein Füllstück 8 angeordnet, welches auf den Schraubenbolzen 7 aufgesteckt ist und die Stoßlücke zwischen den Unterflanschen der Schienenabschnitte 2 und 3 ausfüllt. Auf das Ende des Schraubenbolzens 7 ist eine Mutter 9 aufgeschraubt, die selbsthemmend ausgebildet ist. Wie aus der Zeichnung ersichtlich ist, kann durch Anziehen der Mutter 9 das in der Stoßlücke befindliche Füllstück 8 vorgespannt werden. Aufgrund des Spiels zwischen dem Schraubenbolzen 7 und den Bohrungen in den Befestigungsblöcken 6 können sich die Schienenabschnitte 1 und 2 gegeneinander verschwenken, wobei die Schwenkachse nicht durch die Konstruktion des Gelenkes 4, sondern allein durch die nachfolgend erläuterte Konstruktion der Verbindungsmittel 5 zwischen den Oberflanschen bestimmt ist. Das Gelenk 4 nimmt nur Zugkräfte auf, nicht aber quer zur Schienenlängsrichtung gerichtete Querkräfte.and 2 required game available. Between the mounting blocks 6, a filler 8 is arranged, which is placed on the screw bolt 7 and fills the gap between the lower flanges of the rail sections 2 and 3. A nut 9, which is designed to be self-locking, is screwed onto the end of the screw bolt 7. As can be seen from the drawing, by tightening the nut 9 the filler 8 located in the gap can be prestressed. Due to the play between the bolt 7 and the bores in the mounting blocks 6, the rail sections 1 and 2 can pivot against each other, the pivot axis not being determined by the construction of the joint 4, but solely by the construction of the connecting means 5 between the upper flanges explained below . The joint 4 only absorbs tensile forces, but not transverse forces directed transversely to the longitudinal direction of the rail.

Die Verbindungsmittel 5 zwischen den Oberflanschen bestehen aus Aufhängeblechen 10, die auf die Oberflansche der aneinanderstoßenden Schienenabschnitte 1 bzw. 2 aufgeschweißt sind und sich in Schienenlängsrichtung überlappen. Im Überlappungsbereich sind die Aufhängebleche 10 mit sich deckenden, kreisbogenförmig aufgeweiteten Langlöchern 11 versehen, die zur Aufnahme eines Aufhängebolzens 12 dienen. Dabei liegt der Mittelpunkt 13 der beiden Kreisbögen in der Mitte der Stoßlücke und in der Höhe der Laufflächen 3 auf der Oberseite der Unterflansche der Schienenabschnitte 1 bzw. 2. Der Aufhängebolzen 12 ist an seiner nach oben weisenden Seite abgeflacht ausgebildet, wobei die Abflachung 12a der kreisbogenförmigen Lochleibung der Langlöcher 11 angepaßt ist.The connecting means 5 between the upper flanges consist of suspension plates 10 which are welded onto the upper flanges of the abutting rail sections 1 and 2 and overlap in the longitudinal direction of the rail. In the overlap area, the suspension plates 10 are provided with overlapping, elongated, arc-shaped elongated holes 11, which serve to receive a suspension bolt 12. The center point 13 of the two arcs lies in the middle of the abutment gap and at the height of the treads 3 on the upper side of the lower flanges of the rail sections 1 and 2. The suspension bolt 12 is flattened on its upward-facing side, the flattened portion 12a circular arch reveal of the elongated holes 11 is adapted.

Wie aus Fig. 3 ersichtlich ist, sind die Aufhängebleche an einem Ende jedes Schienenabschnittes 1 bzw. 2 auf der einen Seite der vertikalen Längsmittenebene und am anderen Ende auf der gegenüberliegenden Seite der vertikalen Längsmittenebene angeordnet. Infolgedessen behält die Schiene bei einer Verdrehung um 180 ° um eine senkrecht zur Papierebene verlaufende Mittenachse ihre Konfiguration bei, so daß die Schiene in beiden Richtungen eingebaut werden kann.As can be seen from FIG. 3, the suspension plates are arranged at one end of each rail section 1 or 2 on one side of the vertical longitudinal center plane and at the other end on the opposite side of the vertical longitudinal center plane. As a result, the rail maintains its configuration when rotated by 180 ° about a central axis running perpendicular to the plane of the paper, so that the rail can be installed in both directions.

Der Aufhängebolzen 12 wird von einem Schäkel 14 getragen, der die beiden aneinander zu befestigenden Aufhängebleche umgreift und zusammenhält.The suspension bolt 12 is carried by a shackle 14 which engages around and holds the two suspension plates to be fastened together.

Zum Zusammenbau der aus den Fig. 1 und 2 ersichtlichen Teile wird der Aufhängebolzen 12 aus dem Schäkel 14 herausgezogen. Dann wird der Schäkel 14 so über die beiden Aufhängebleche 10 gesteckt, daß die Bolzenaugen im Schäkel 14 mit den beiden Langlöchern 11 fluchten. Abschließend wird der Aufhängebolzen 12 eingesteckt und durch geeignete Sicherungsmittel 15 gegen Herausfallen gesichert.To assemble the parts shown in FIGS. 1 and 2, the suspension bolt 12 is pulled out of the shackle 14. Then the shackle 14 is placed over the two suspension plates 10 so that the bolt eyes in the shackle 14 are aligned with the two elongated holes 11. Finally, the suspension bolt 12 is inserted and secured against falling out by suitable securing means 15.
