Description

Die Erfindung betrifft eine Gelenkkupplung für Fahrzeugeinheiten von Schienenfahrzeugen nach dem Oberbegriff des Anspruchs 1.The invention relates to a universal joint for vehicle units of rail vehicles according to the preamble of claim 1.

Gelenkverbindungen zwischen Triebzugwagen beruhen häufig auf dem Prinzip von Gabel-Lasche-Konstruktionen. Bei diesen wird in der Regel ein Bolzen als Verbindungselement durch Bohrungen der Gabelwangen und der Lasche gesteckt. Bei der Koppelung von Schienenfahrzeugen ist diese Montageart im allgemeinen nicht möglich, da die erforderliche Fluchtung der Bohrungen von Lasche und Gabelwangen nicht hergestellt werden kann. Aus diesem Grunde sind die Gabelwangen nicht gebohrt, sondern horizontal mit Halbschalen versehen, in die der in der Laschenbohrung steckende Bolzen abgelegt werden kann. Wie beim geteilten Lager wird er von einem Gegenstück, einer aufgeschraubten zweiten Halbschale, niedergehalten und befestigt.Joint connections between multiple units are often based on the principle fork-and-fork constructions. These are usually a bolt as Connecting element inserted through holes in the fork cheeks and the tab. When coupling rail vehicles this type of mounting is in general not possible, because the required alignment of the holes of tab and fork cheeks can not be made. That's why the fork cheeks not drilled, but horizontally provided with half shells, in which the stuck in the tab hole bolts can be stored. As in the shared camp he is a counterpart, a screwed second half-shell, held down and fastened.

Eine bekannte Lösung dieser Art zeigt die DE 41 21 080 A1. Diese Kupplungsvorrichtung für die auf einem gemeinsamen Drehgestell abgestützten Enden zweier gelenkig miteinander verbundener Fahrzeugeinheiten besteht aus einem an der einen Fahrzeugeinheit befestigten, zwei seitliche Gabelwangen aufweisenden Gabelkopf, einer an der anderen Fahrzeugeinheit befestigten, zwischen die beiden Gabelwangen eingeschobenen Verbindungslasche und einem Kupplungsbolzen mit in der Verbindungslasche angeordnetem sphärischen Lager. Das sphärische Lager ist mit dem Kupplungsbolzen fest in der Verbindungslasche angeordnet. Beide Gabelwangen weisen horizontal geteilte, aus einer unteren, festen und einer oberen, lösbaren Lagerschale bestehende Lager auf, über die der Kupplungsbolzen in den Gabelwangen festklemmbar ist. Eine andere Gabel-Lasche-Konstruktion zeigt die DE 44 04 878 C1. Hier wird der Kupplungsbolzen in den Gabelwangen bzw. in zwei darin eingeformten, prismatischen Auflagern mittels Lagerdeckeln gleichfalls von oben festgelegt.A known solution of this kind is shown in DE 41 21 080 A1. This coupling device for the ends supported on a common bogie two articulated vehicle units consists of a attached to the one vehicle unit, having two lateral fork cheeks Clevis, one attached to the other vehicle unit, between the two fork cheeks inserted connecting strap and a Coupling pin with arranged in the connecting plate spherical bearing. The spherical bearing is firmly in the connecting plate with the coupling pin arranged. Both fork cheeks have horizontally split, off a lower, fixed and an upper, detachable bearing shell existing bearings on, over which the coupling pin is clamped in the fork cheeks. A another fork-flap construction shows the DE 44 04 878 C1. Here is the Coupling pin in the fork cheeks or in two molded therein, prismatic Auflagern by means of bearing caps also set from above.

Die genannten Lösungen haben den Nachteil, daß der Kupplungsbolzen durch die verwendete Klemmverbindung keine definierte Lage einnimmt. Außerdem ist bei Verwendung von üblichen Schraubverbindungen eine dauerhafte Sicherheit der Schraubverbindungen gegen Lösen nicht mit ausreichender Sicherheit zu gewährleisten.The solutions mentioned have the disadvantage that the coupling pin through the clamp connection used assumes no defined position. Besides that is when using conventional screw permanent security the screw against loosening with sufficient security too guarantee.

Der Erfindung liegt daher die Aufgabe zugrunde, die bekannten Gelenkkupplungen, die auf dem Gabel-Lasche-Prinzip beruhen, derart auszubilden, daß die Festlegung des Sphärogelenkbolzens in definierter Lage erfolgen kann.The invention is therefore based on the object, the known universal joints, which are based on the fork-flap principle, form such that the Determination of Sphärogelenkbolzens can take place in a defined position.

Noch der Erfindung wird dieses durch die Merkmale des Patentanspruches 1 erreicht. Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen 2 bis 14 angegeben.Still the invention, this is characterized by the features of claim 1 reached. Advantageous embodiments of the invention are in the subclaims 2 to 14 indicated.

Ein Vorteil der Erfindung liegt in einem einfachen Kuppeln und Entkuppeln der Fahrzeuge, wobei je nach Fahrzeugbauart die günstigste Richtung des Kuppelvorganges realisiert werden kann. Weiterhin gestattet die Erfindung eine spielfreie, eindeutige Bolzenbefestigung in der Gabel. Der Sphärogelenkbolzen wird in festen Kupplungsgabel-Halbschalen entweder von oben abgelegt oder horizontal-längs oder von unten eingeführt und erhält dabei eine erste Zentrierung. Die eigentliche Halterung des Bolzens erfolgt jedoch durch Zapfen in Bohrungen der Gabelwangen der Kupplungsgabel, nicht in geschraubten Klemmverbindungen. Mit Hilfe eines Kegelsitzes wird eine Art Verlängerung des Bolzens erzielt, der, wie bei den konventionellen Gabel-Lasche-Verbindungen, durch alle Bohrungen fluchtend hindurchgeht. Die Kegel zentrieren und klemmen den Sphärogelenkbolzen und halten ihn in eindeutiger Lage. Der Bolzen wird so ähnlich gehalten wie ein "zwischen Spitzen" zu drehendes Werkstück.An advantage of the invention lies in a simple coupling and uncoupling of Vehicles, depending on the type of vehicle the most favorable direction of the coupling process can be realized. Furthermore, the invention allows a backlash-free, clear bolt fastening in the fork. The Sphärogelenkbolzen is stored in fixed clutch fork half-shells either from above or horizontally-longitudinally or introduced from below and thereby receives a first centering. However, the actual mounting of the bolt is done by pins in holes the fork cheeks of the clutch fork, not in screwed clamp connections. With the help of a conical seat is a kind of extension of the bolt achieved, as in the conventional fork-tab connections, passes through all holes in alignment. Center and clamp the cones the Sphärogelenkbolzen and keep it in a unique position. The bolt is considered to be similar to a "between points" to be rotated workpiece.

Durch die Festlegung des Zapfens über einen gesonderten Deckel gemäß Anspruch 2 mit lösbaren Befestigungsmitteln (Schrauben) können diese eine eindeutige Verbindung zwischen Deckel und Kupplungsgabel unabhängig von der Funktion des Klemmens des Zapfens herstellen. Die Funktion des Klemmens wird über ein Druckelement erzeugt.By fixing the pin on a separate cover according to claim 2 with releasable fasteners (screws), these can be a unique Connection between cover and clutch fork regardless of the Establish the function of clamping the pin. The function of clamping is generated via a pressure element.

Durch die Ausbildung der Befestigung der Zapfen gem. Anspruch 11 mit lösbaren Befestigungsmitteln, insbesondere Schrauben, die durch Spannhülsen querkraftfrei gehalten sind, wird die dauerhafte Sicherheit gegen selbsttätiges Losdrehen der lösbaren Befestigungsmittel deutlich verbessert.By training the attachment of the pin gem. Claim 11 with detachable Fasteners, in particular screws, the transverse force free by clamping sleeves are held, the permanent security against automatic loosening the releasable fastener significantly improved.
