Description

Die Erfindung betrifft eine Zugeinrichtung für Schienenfahrzeuge, im wesentlichen bestehend aus einer am Fahrzeug anschließbaren Stützplatte, einer die Stützplatte durchdringenden Zugstange und einer Feder, vorzugsweise einer Reibungsfeder, wobei die Zugstange an ihrem vorderen Ende einen Kupplungskörper und an ihrem hinteren Ende eine unter Anordnung eines Zugelementes mit der Feder zusammenwirkende Mutter aufweist und die äußere Mantelfläche der Feder von einem Gehäuse umgeben ist.The invention relates to a pulling device for rail vehicles, consisting essentially of a support plate which can be connected to the vehicle, a pull rod penetrating the support plate and a spring, preferably a friction spring, the pull rod having a coupling body at its front end and a coupling element at its rear end has cooperating with the spring nut and the outer surface of the spring is surrounded by a housing.

Zugeinrichtungen mit den vorgenannten Merkmalen sind durch die Druckschrift der Anmelderin "Mitteilungen aus dem Konstruktionsbüro 1/78" bekannt. Bei diesen Zugeinrichtungen sind die Stützplatte und das Gehäuse über eine Schraubenanordnung miteinander verbunden. Die innerhalb des Gehäuses befindliche Reibungsfeder liegt gegen die Stützplatte an und erhält ihre Vorspannung über das Zugelement durch die auf der Zugstange gehaltene Mutter. Die fahrzeugseitige Montage einer solchen Zugeinrichtung . erfolgt als bauliche Einheit durch Befestigen der Stützplatte am Trägerwerk des Fahrzeuges.Towing devices with the aforementioned features are known from the applicant's publication "Messages from the Design Office 1/78". In these traction devices, the support plate and the housing are connected to one another via a screw arrangement. The friction spring located inside the housing bears against the support plate and receives its pretension via the tension element through the nut held on the tension rod. The vehicle-side assembly of such a traction device. takes place as a structural unit by attaching the support plate to the carrier structure of the vehicle.

Gemäß dem weiter zum Stand der Technik gehörenden UIC-Merkblatt 520 sind die Stützplatte und die Zugstange standardisierte Bauteile, wobei die Wahl der Feder freigestellt wird. Die in Verbindung mit diesen standardisierten Bauteilen in der Praxis gebräuchlichen Gummifedern haben nachteilig eine vergleichsweise geringe Lebensdauer und reichen bei den gestiegenen Fahrzeuggewichten hinsichtlich.ihres Arbeitsvermögens nicht aus.According to UIC leaflet 520, which also belongs to the state of the art, the support plate and the tie rod are standardized components, the choice of the spring being free is provided. The rubber springs commonly used in practice in connection with these standardized components have a comparatively short lifespan and are not sufficient in terms of their working capacity due to the increased vehicle weights.

Der Erfindung liegt die Aufgabe zugrunde, eine Zugeinrichtung der gattungsgemäßen Art so auszubilden, daß Feder und Gehäuse als kompaktes, einbaufertiges Gebilde unter einfachem Aufschieben auf die Zugstange mit der beispielsweise nach UIC-Merkblatt 520 gestalteten Stützplatte zusammengefügt werden können.The invention has for its object to provide a traction device of the generic type so that the spring and housing can be assembled as a compact, ready-to-install structure by simply sliding onto the pull rod with the support plate designed, for example, according to UIC Leaflet 520.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Feder einerseits an der Innenfläche einer vorderen, gegen die Stützplatte anlegbaren Grundplatte und andererseits - insbesondere bei noch nicht montierter Mutter - über das Zugelement an einem einwärts gerichteten Kragen des zugfest mit der Grundplatte verbundenen Gehäuses unter Vorspannung abgestützt ist.This object is achieved in that the spring is supported on the one hand on the inner surface of a front base plate which can be placed against the support plate and on the other hand - in particular with a nut which has not yet been mounted - via the tension element on an inwardly directed collar of the housing connected to the base plate with tensile strength under pretension is.

Bei der Zugeinrichtung nach der Erfindung sind vorteilhaft die Feder und das Gehäuse zu einem einbaufertigen, die Vorspannung für die Feder enthaltenden Gebilde vereinigt. Die derartige Federkapsel kann freizügig verwendet, das heißt, allen in der Praxis gebräuchlichen Stützplatten, z.B. nach UIC-Merkblatt 520 oder einem fahrzeugseitigen Träger, nachgeschaltet werden. Dazu wird die Federkapsel lediglich auf die Zugstange geschoben und gegen die Stützplatte angelegt, wobei durch nachfolgendes Aufschrauben und Anziehen der Mutter nur um den Bruchteil einer Umdrehung die Vorspannung der Feder über die Grundplatte auf die Stützplatte wirksam wird. Dieser Zusammenbau von Stützplatte und Federkapsel ist bei der Erstausrüstung und in Ersatzfällen, beispielsweise Wegfall der Gummifeder, in günstiger Weisebei im Fahrzeug angeschlossener Stützplatte möglich; ein Ausbau der vorgespannt bleibenden Federkapsel kann gleichfalls unter Belassen der Stützplatte erfolgen. Auch bei einem schnell durchführbaren Tausch der Zugstange, z.B: bei größerem Verschleiß, bleibt die Federkapsel in ihrer Vorspannung unverändert.In the pulling device according to the invention, the spring and the housing are advantageously combined to form a ready-to-install structure containing the pretension for the spring. The spring capsule of this type can be used freely, that is to say it can be connected downstream of all the support plates which are customary in practice, for example according to UIC leaflet 520 or a vehicle-side carrier. For this purpose, the spring capsule is simply pushed onto the pull rod and placed against the support plate, with the subsequent screwing and tightening of the nut only by a fraction of a turn, the bias of the spring on the base plate on the support plate. This assembly of the support plate and spring capsule is possible in the original equipment and in replacement cases, for example the rubber spring is omitted, in a favorable manner with the support plate connected in the vehicle; the spring capsule, which remains under tension, can also be removed while leaving the support plate. The spring capsule remains unchanged in its preload even when the pull rod can be replaced quickly, e.g. in the event of greater wear.

Eine fertigungstechnisch besonders rationelle, die Vorspannkraft der Feder aufnehmende und im übrigen absolut dichte Verbindung zwischen der Grundplatte und dem Gehäuse wird nach einer Ausgestaltung der Erfindung dadurch erreicht, daß die Grundplatte und das Gehäuse durch Schweißen miteinander verbunden sind.A particularly efficient manufacturing technology, absorbing the biasing force of the spring and otherwise absolutely tight connection between the base plate and the housing is achieved according to one embodiment of the invention in that the base plate and the housing are connected to one another by welding.

Zum Erzielen einer definierten Anordnung der Zugstange besteht eine nächste Ausführungsform der Erfindung darin, daß die Grundplatte die Zugstange im Sinne einer Führung aufnimmt. Diese Führung erleichtert den Zusammenbau von Zugstange und Federkapsel und stellt die Funktion der Zugeinrichtung im Betrieb auch dann sicher, wenn die Stützplatte keine oder nur eine unzureichende Führung für die Zugstange aufweist.In order to achieve a defined arrangement of the pull rod, a next embodiment of the invention is that the base plate receives the pull rod in the sense of a guide. This guide facilitates the assembly of the drawbar and spring capsule and ensures the function of the drawbar in operation even when the support plate has no or insufficient guidance for the drawbar.

Vor allem im Hinblick auf eine bessere Stabilisierung des Zugelementes und der daran abgestützten Feder beim Arbeitshub der Zugeinrichtung ist gemäß einem weiteren Merkmal der Erfindung vorgesehen, daß die Grundplatte einen rohrförmigen Ansatz aufweist und über diesen Ansatz eine Führung für das Zugelement bildet. Bei dieser Führung kann der mit entsprechender Länge ausgeführte rohrförmige Ansatz der Grundplatte unmittelbar die äussere Umfangsfläche des Zugelementes erfassen. Eine andere Gestaltungsmöglichkeit der Führung besteht in einem teleskopartigen Zusammenfügen des rohrförmigen Ansatzes der Grundplatte und einer in oder auf diesem Ansatz angeordneten Verlängerung des Zugelementes.Especially with a view to better stabilizing the tension element and the spring supported on it during the working stroke of the tension device, it is provided according to a further feature of the invention that the base plate has a tubular extension and forms a guide for the tension element via this extension. With this guide, the tubular extension of the base plate with a corresponding length can directly grasp the outer circumferential surface of the tension element. Another design option for the guide consists in a telescopic assembly of the tubular extension of the base plate and an extension of the tension element arranged in or on this extension.

Für eine direkte Einleitung der beispielsweise beim Durchfahren eines Gleisbogens auftretenden Querkräfte in das Fahrzeuguntergestell sieht eine weitere Ausgestaltung nach der Erf-indung vor, daß die Grundplatte in der Horizontalen eine der entsprechenden Abmessung des Einbauraumes für die Zugeinrichtung angeglichene Breite aufweist und über ihre vertikalen Seitenflächen gegen die den Einbauraum seitlich begrenzenden Flächen anliegt.For a direct introduction of the transverse forces that occur, for example, when driving through a curved track, into the vehicle undercarriage, a further embodiment provides, according to the invention, that the horizontal base plate has a width that is equal to the corresponding dimension of the installation space for the traction device and counteracts it via its vertical side surfaces which rests on the surfaces delimiting the installation space.

Um eine auch bei der Montage nützliche senkrechte Abstützung für die Federkapsel zu schaffen, liegt es ferner im Wesen der Erfindung, daß die Grundplatte mit einem gegen einen horizontalen Flansch der Stützplatte anliegenden Steg versehen ist.In order to provide a vertical support for the spring capsule, which is also useful during assembly, it is also in the essence of the invention that the base plate is provided with a web resting against a horizontal flange of the support plate.

Nach einer erfindungsgemäßen Weiterbildung weist die Grundplatte an ihrer der Stützplatte zugewandten Außenfläche eine vertikal angeordnete Nut auf. Diese Nut erbringt vorteilhaft ein unmittelbares Abführen von Feuchtigkeit, die möglicherweise an der Durchtrittstelle der Zugstange durch die Stützplatte oder zwischen dieser Platte und der Grundplatte anfällt.According to a development according to the invention, the base plate has a vertically arranged groove on its outer surface facing the support plate. This groove advantageously brings about a direct removal of moisture, which possibly occurs at the point of passage of the pull rod through the support plate or between this plate and the base plate.

Im Sinne optimaler Eigenschaften der Federkapsel im Betrieb besteht eine ergänzende Ausführungsform der Erfindung darin, daß das Zugelement und das Gehäuse im hinteren Bereich der Zugeinrichtung im Sinne einer Führung ausgebildet sind.In terms of optimal properties of the spring capsule during operation, a supplementary embodiment of the invention is that the tension element and the housing in the rear area of the tension device are designed in the manner of a guide.

Zum Erzielen einer noch besseren, bereits durch die nachstehend genannten, labyrinthartig wirkenden Führungen gegebenen inneren Abschirmung der Feder gegen Staub und Feuchtigkeit sowie im Hinblick auf ein besonders leichtgängiges Zusammenarbeiten dieser Führungen ist nach einer weiteren Ausgestaltung der Erfindung vorgesehen, daß innerhalb der jeweiligen Führung - zwischen der Grundplatte mit dem rohrförmigen Ansatz und der Zugstange;In order to achieve an even better internal shielding of the spring against dust and moisture, which is already provided by the labyrinth-like guides mentioned below, and with a view to a particularly smooth cooperation of these guides, according to a further embodiment of the invention it is provided that within the respective guide - between the base plate with the tubular extension and the pull rod;

zwischen der Grundplatte mit dem rohrförmigen Ansatz und dem Zugelement; zwischen dem Zugelement und dem Gehäuse - eine zugleich dem Abdichten dienende Gleitbuchse angeordnet ist.between the base plate with the tubular extension and the tension element; between the tension element and the housing - a sliding bushing which is also used for sealing is arranged.

Um auch bei einer kurzen Baulänge der Zugstange eine möglichst lange Feder mit entsprechend großem Arbeitsvermögen einsetzen zu können, empfiehlt sich eine Anordnung der Mutter innerhalb der Federkapsel, deren Zugelement dann topfartig gestaltet ist. Eine dabei erforderliche Montageöffnung für die Mutter im hinten liegenden Boden des Gehäuses kann mittels einer über den Gehäuseboden gestülpten Verschlußkappe dicht abgedeckt werden, wobei ein übliches Spannband diese Kappe hält. Ein alternatives Merkmal gemäß der Erfindung, wonach der einwärts gerichtete Kragen des Gehäuses zur Aufnahme eines das Gehäuse dicht verschließenden Deckels ausgebildet ist, erlaubt einen besonders einfach gestalteten Deckel und dessen Befestigung ohne separate Teile.In order to be able to use the longest possible spring with a correspondingly large working capacity even with a short overall length of the pull rod, it is advisable to arrange the nut inside the spring capsule, the pull element of which is then designed like a pot. A necessary assembly opening for the mother in the rear floor of the housing can be covered tightly by means of a sealing cap placed over the housing base, a customary strap holding this cap. An alternative feature according to the invention, according to which the inwardly directed collar of the housing is designed to receive a cover that tightly seals the housing, permits a particularly simple cover and its attachment without separate parts.

Die Zugeinrichtungen gemäß den Figuren 1 bis 3 enthalten eine als Reibungsfeder mit ineinandergreifenden konischen Ringen ausgebildete Feder 1. Diese Feder 1 ist unter Vorspannung über ihr vorderes Ende gegen die Innenfläche 3a einer Grundplatte 3 und bei noch nicht montierter Mutter 4 über ihr hinteres Ende unter Anordnung eines Zugelementes 5-gegen einen einwärts gerichteten Kragen 6a eines Gehäuses 6 abgestützt, welches die Mantelfläche der Feder 1 umgibt. Zur Aufnahme der Federvorspannung sind die Grundplatte 3 und das Gehäuse 6 zugfest, in den vorliegenden Beispielen durch Schweißen, miteinander verbunden.The pulling devices according to FIGS. 1 to 3 contain a spring 1 designed as a friction spring with interlocking conical rings. This spring 1 is under Tension is supported via its front end against the inner surface 3a of a base plate 3 and, if the nut 4 has not yet been mounted, via its rear end by arranging a tension element 5 against an inwardly directed collar 6a of a housing 6 which surrounds the outer surface of the spring 1. To accommodate the spring preload, the base plate 3 and the housing 6 are connected to one another in a tensile manner, in the present examples by welding.

Weiter nach den Figuren 1 bis 3 liegt die jeweilige Grundplatte 3 gegen eine Stützplatte 2 an, die über einen horizontalen Flansch 2a am Fahrzeug angeschraubt werden kann. Die Stützplatte 2 wird von einer Zugstange 7 durchdrungen, die vorne einen Kupplungskörper 7a, beispielsweise den gezeigten Gabelkopf zum gelenkigen Aufnehmen eines Zughakens, und hinten die Mutter 4 aufweist. Die Mutter 4 arbeitet über das Zugelement 5 mit der Feder 1 zusammen, deren Vorspannung durch Anziehen der Mutter 4 nur um den Bruchteil einer Umdrehung über die Grundplatte 3 auf die Stützplatte 2 wirksam wird; zwischen dem Zugelement 5 und dem Kragen 6a des Gehäuses 6 kann dann - siehe Fig. 1, obere Hälfte - ein kleiner Abstand bestehen.Further according to FIGS. 1 to 3, the respective base plate 3 bears against a support plate 2 which can be screwed onto the vehicle via a horizontal flange 2a. The support plate 2 is penetrated by a pull rod 7, which has a coupling body 7a at the front, for example the fork head shown for articulated accommodation of a pulling hook, and the nut 4 at the rear. The nut 4 works via the tension element 5 with the spring 1, the pretensioning of which is only effective by tightening the nut 4 by a fraction of a turn via the base plate 3 on the support plate 2; between the tension element 5 and the collar 6a of the housing 6 can then - see Fig. 1, upper half - there is a small distance.

Die Grundplatten 3 sind jeweils mit einem rohrförmigen Ansatz 3b versehen, der bei Fig. 1 nahe der Zugstange 7 und gemäß Fig. 2 und 3 von der Zugstange 7 entfernt angeordnet ist. Durch das teleskopartige Zusammenwirken des rohrförmigen Ansatzes 3b mit einer Verlängerung 5a des Zugelementes 5 (Fig. 1 und Fig*. 2) oder der äußeren Umfangsfläche des Zugelementes 5 (bei Fig. 3) wird dieses Element 5 stabilisiert. Weiter nimmt die jeweilige Grundplatte 3 die Zugstange 7 im Sinne einer Führung auf. Dazu dient in der Gestaltung nach Fig. 1 ebenfalls der rohrförmige Ansatz 3b; in den Ausführungen nach Fig. 2 und 3 haben die Grundplatten 3 eine entsprechende Erstreckung in Längsrichtung. Im übrigen sind bei den Zugeinrichtungen der Fig. 2 und 3 das Zugelement 5 und das Gehäuse 6, wie ersichtlich, im Sinne einer Führung ausgebildet.The base plates 3 are each provided with a tubular extension 3b, which is arranged near the pull rod 7 in FIG. 1 and away from the pull rod 7 according to FIGS. 2 and 3. This element 5 is stabilized by the telescopic interaction of the tubular extension 3b with an extension 5a of the tension element 5 (FIGS. 1 and 2) or the outer peripheral surface of the tension element 5 (in FIG. 3). Furthermore, the respective base plate 3 receives the pull rod 7 in the sense of a guide. The tubular extension 3b also serves this purpose in the design according to FIG. 1; 2 and 3, the base plates 3 have a corresponding Er Elongation in the longitudinal direction. 2 and 3, the traction element 5 and the housing 6, as can be seen, are designed in the manner of a guide.

Innerhalb der vorbezeichneten Führungen ist jeweils eine Gleitbuchse 9 angeordnet, die neben einem leichtgängigen Zusammenwirken dieser Führungen für eine gegen Staub und Feuchtigkeit zuverlässige Abschirmung der Feder 1 sorgt. Diese Abschirmung kann durch einen in Fig. 1 gezeigten Balg 10, der an dem rohrförmigen Ansatz 3b der Grundplatte 3 und an dem Zugelement 5 befestigt ist, zusätzlich gesichert werden. In diesem Sinne wirkt auch eine Ringnut 3g im rohrförmigen Ansatz 3b der Grundplatte 3, die gegebenenfalls von der Verlängerung 5a des Zugelementes 5 abgeschabte Verunreinigungen an der Gleitbuchse 9 aufnimmt. Die Gleitbuchse 9 zwischen der Grundplatte 3 und der Zugstange 7 wird in allen Fällen durch eine Nut 3f in der Außenfläche 3e der Grundplatte 3 von Feuchtigkeit weitgehend freigehalten, wobei diese Nut 3f gemäß Fig. 2 und 3 über Bohrungen 3h mit dem Raum zwischen der Zugstange 7 und dem rohrförmigen Ansatz 3b hinsichtlich einer Entwässerung in Verbindung steht.A slide bushing 9 is arranged within each of the above-mentioned guides and, in addition to the smooth interaction of these guides, ensures that the spring 1 is shielded reliably against dust and moisture. This shielding can be additionally secured by a bellows 10 shown in FIG. 1, which is fastened to the tubular extension 3b of the base plate 3 and to the tension element 5. In this sense, an annular groove 3g also acts in the tubular extension 3b of the base plate 3, which, if appropriate, picks up contaminations on the sliding bushing 9 scraped off by the extension 5a of the tension element 5. The sliding bush 9 between the base plate 3 and the pull rod 7 is largely kept free of moisture in all cases by a groove 3f in the outer surface 3e of the base plate 3, this groove 3f according to FIGS. 2 and 3 via bores 3h with the space between the pull rod 7 and the tubular extension 3b with respect to drainage.

Die Grundplatte 3 der Zugeinrichtung nach Fig. 1 weist - siehe Fig. 4 - in der Horizontalen eine der entsprechenden Abmessung des Einbauraumes angeglichene Breite auf und liegt über ihre vertikalen Seitenflächen 3c gegen die den Einbauraum seitlich begrenzenden Flächen 8 an. Im Fahrbetrieb auftretende Querkräfte werden dadurch direkt in das Untergestell eingeleitet. Die Grundplatte 3 der in den Figuren 2 und 3 gezeigten Zugeinrichtungen kann entsprechend ausgebildet sein. Wird auf eine solche Verbreiterung der Grundplatte 3 verzichtet, so erfolgt die Querkrafteinleitung über die großflächige, mit Federvorspannung beaufschlagte Anlage der Grundplatte 3 an der Stützplatte 2.The base plate 3 of the traction device according to FIG. 1 has - see FIG. 4 - a width that is equal to the corresponding dimension of the installation space in the horizontal and bears against its surfaces 8c that laterally delimit the installation space via its vertical side surfaces 3c. As a result, transverse forces that occur while driving are introduced directly into the underframe. The base plate 3 of the pulling devices shown in FIGS. 2 and 3 can be designed accordingly. If such a widening of the base plate 3 is dispensed with, then the introduction of transverse force takes place via the large-area bearing of the base plate 3 on the support plate 2, which spring preload is applied.

Weiter ist in den Fig: 1 und 4 mit strichpunktierten Linien ein Steg 3d an der Grundplatte 3 dargestellt, wobei der Steg 3d gegen den horizontalen Flansch 2a der Stützplatte 2 anliegt. Diese Abstützung erleichtert das Anbringen der Federkapsel und wirkt als Verdrehsicherung. Die in Fig. 4 ebenfalls strichpunktiert gezeigten vier Bohrungen in der Grundplatte 3 sind für den Fall vorgesehen, in dem eine Schraubverbindung zwischen der Grundplatte 3 und der Stützplatte 2 gewünscht wird.1 and 4, a web 3d is shown on the base plate 3 with dash-dotted lines, the web 3d resting against the horizontal flange 2a of the support plate 2. This support facilitates the attachment of the spring capsule and acts as an anti-rotation device. The four bores in the base plate 3, also shown in dash-dotted lines in FIG. 4, are provided for the case in which a screw connection between the base plate 3 and the support plate 2 is desired.

Eine Montageöffnung im Boden des Gehäuses 6 für die innerhalb des Zugelementes 5 angeordnete Mutter 4 ist gemäß Fig. 1 und 2 durch eine über den Gehäuseboden gestülpte Verschlußkappe 11 mit Spannband 11a dicht abgedeckt. Nach Fig. 3 nimmt der entsprechend gestaltete Kragen 6a des Gehäuses 6 einen Deckel 6b auf, der ebenfalls das Gehäuse 6 dicht verschließt.An assembly opening in the bottom of the housing 6 for the nut 4 arranged within the tension element 5 is, according to FIGS. 1 and 2, tightly covered by a closure cap 11 with a tensioning strap 11a placed over the bottom of the housing. 3, the correspondingly designed collar 6a of the housing 6 receives a cover 6b which also tightly closes the housing 6.

Anhand von Fig. 1 wird hinsichtlich der Arbeitsfunktion der Zugeinrichtung bemerkt, daß eine über den Kupplungskörper 7a mit daran angeschlossenem Zughaken eingeleitete Zugkraft über Zugstange 7, Mutter 4, Zugelement 5, Feder 1, Grundplatte 3 und Stützplatte 2 in das Fahrzeuguntergestell eingeleitet wird.1 with regard to the working function of the pulling device, it is noted that a pulling force introduced via the coupling body 7a with a pulling hook connected to it is introduced into the vehicle undercarriage via pulling rod 7, nut 4, pulling element 5, spring 1, base plate 3 and support plate 2.
