Abstract

The invention relates to a coupling for scheduled services, with which a locomotive is coupled, either for shunting work or else for scheduled work, to a carriage equipped either with a coupling hook or a central buffer, release of the coupling from the coupling hook being prevented during scheduled work or shunting work by means of a working cylinder and a locking bolt. Coupling can also be carried out with a carriage which has a structure above the carriage coupling hook which prevents coupling from above. According to the invention (Fig. 1), the lever (3) and the bar (5) are pressed continuously downwards into position (a) against the coupling hook (1) with the aid of the working cylinder (8) and of the locking bolt (10) when the coupling is coupled, the bar (5) being tensioned in such a way that despite the alternating load states, it remains securely on the coupling hook. If a central buffer (2) is to be coupled to a central buffer of a carriage, the bar (5) and the lever (3) are located in a position (e) below the abovementioned position. <IMAGE>

Description

Unter einer Rangierkupplung ist hier eine Kupplung zu verstehen, mit welcher der Lokomotivführer von seiner Kabine aus die Lokomotive und den Wagen zusammenkuppelt, mit anderen Worten wird die Lokomotive während der Rangierarbeit schnell und leicht an der Zugeinheit gekuppelt und von der Zugeinheit entkuppelt.A shunting coupling is understood here to mean a coupling with which the locomotive driver couples the locomotive and the wagons from his cabin, in other words the locomotive is quickly and easily coupled to the train unit during the shunting work and uncoupled from the train unit.

Unter einer Linienfahrtkupplung ist hier eine Kupplung zu verstehen, welche der vorher erwähnten Kupplung ähnlich ist aber auch zu Linienfahrt passt.A line clutch is to be understood here as a clutch which is similar to the clutch mentioned above but also fits line service.

Heutzutage werden in den zu UIC gehörenden Ländern Zughaken und sogenannte Schraubenkupplungen als Kupplungen sowohl zwischen den Wagen als auch zwischen der Lokomotive und den Wagen verwendet. Dabei sind die Wagen und die Lokomotiven mit Seitenpuffern versehen.Nowadays, pulling hooks and so-called screw couplings are used as couplings between the wagons as well as between the locomotive and the wagons in the countries belonging to UIC. The cars and locomotives are equipped with side buffers.

Ein anderes, z.B. in den Vereinigten Staaten und der Sowjetunion zwischen den Wagen und der Lokomotive sowie zwischen den verschiedenen Wagen verwendetes Kupplungselement ist der sogenannte Zentralpuffer, der sich wenn die Wagen aneinander gedrückt werden immer automatisch ankuppelt. Die mit den Zentralpuffern ausgerüsteten Wagen haben keinen Seitenpuffer.Another, e.g. In the United States and the Soviet Union, the coupling element used between the cars and the locomotive and between the various cars is the so-called central buffer, which always couples itself automatically when the cars are pressed together. The wagons equipped with the central buffers have no side buffers.

Die mit Zughaken versehenen Wagen können nicht ohne weiteres mit den mit Zentralpuffern versehenen Wagen zusammengekoppelt werden.The wagons fitted with towing hooks cannot easily be coupled together with the wagons provided with central buffers.

Der Aufbau der Wechselkupplung laut dem Patent Nr. FI 78031 stellt eine Verbesserung des Aufbaus gemäss dem Patent Nr. FI 41039 dar, bei welchem z.B. die Übergangsbrücke des Passagierwagens das Kuppeln des Zugbügels von oben an dem Zughaken verhindert.The design of the interchangeable coupling according to Patent No. FI 78031 represents an improvement of the design according to Patent No. FI 41039, in which e.g. the transition bridge of the passenger car prevents the pulling bracket from being coupled to the pulling hook from above.

Diese Erfindung betrifft eine derartige Ergänzung der obenerwähnten Rangierkupplungen, der sogenannten VAPITI-Kupplungen, dass sie auch als Linienfahrtkupplungen zum Ziehen von Schnellzügen verwendet werden können. Der Aufbau gemäss dem Patent Nr. FI 78031 oder FI 41039 eignet sich am besten für die Rangierarbeit und er kann nicht unbedingt beim Ziehen von Passagier- oder Güterzügen in der Linienfahrt benutzt werden, denn man hat es für möglich gehalten, dass der Zugbügel sich durch den Einfluss von schnellen Rucken oder Trägheitskräften vom Haken lösen könnte. Die Verbesserung gemäss der Erfindung versichert, dass schnelle Rucke und Trägheitskräfte, z.B. beim Ziehen eines Schnellzuges, nicht ein Lösen des Kupplungsbügels vom Zughaken des Zuges verursachen werden.This invention relates to such a supplement to the above-mentioned shunting couplings, the so-called VAPITI couplings, that they can also be used as line couplings for pulling express trains. The structure according to patent no. FI 78031 or FI 41039 is best suited for shunting and it cannot necessarily be used when pulling passenger or freight trains on scheduled services, because it has been considered possible that the pulling bracket will go through could loosen the influence of quick jerks or inertial forces from the hook. The improvement according to the invention ensures that fast jerks and inertial forces, e.g. when pulling an express train, will not cause the coupling bracket to loosen from the pull hook of the train.

Die die Erfindung kennzeichnenden Merkmale sind in dem kennzeichnenden Teil der Patentansprüche angegeben.The features characterizing the invention are specified in the characterizing part of the claims.

Die Erfindung wird nachstehend durch die anliegenden Zeichnungen geschildert, wobei Fig 1 die verschiedenen Funktionstellungen der Linienfahrtkupplung darstellt, und Fig 2 die Funktion des Sperriegels der erfindungsgemässen Kupplung illustriert.The invention is illustrated below by the accompanying drawings, in which FIG. 1 shows the various functional positions of the line clutch, and FIG. 2 illustrates the function of the locking bolt of the clutch according to the invention.

In Fig 1 sind die folgenden Stellungen eines Hebels 3 gezeigt: a) Fahrtstellung, b) Verkupplungsstellung, c) Entkupplungsstellung und d) Vertikalstellung.1 shows the following positions of a lever 3: a) driving position, b) coupling position, c) uncoupling position and d) vertical position.

Beim Kuppeln einer Lokomotive an einem Wagen mit der Rangierkupplung gemäss dem Patent 78031, fährt der Fahrer den Lokomotivenpuffer zur Anlage gegen den Wagenpuffer, wobei der Hebel 3 und sein Bügel 5 sich ungefähr auf der Horizontalebene befinden (Stellung b) und der Bügel entlang der schrägen Oberkante des Zughakens 1 der Lokomotive auf diesen Zughaken gebracht wird, so dass der Vorderteil des Bügels auf den Zughaken fällt. Danach lässt der Fahrer den Hebel durch sein eigenes Gewicht mittels eines Arbeitszylinders 8 in die Fahrtstellung a fallen. Dabei biegt sich der Gelenkpunkt 4 zwischen dem Hebel 3 und dem Bügel 5 nieder. Die Lokomotive wird wiederum von dem Wagen dadurch entkuppelt, dass der Fahrer, der sich in der Fahrerkabine befindet, durch betätigen eines Druckventils den Hebel 3 mit Hilfe des Arbeitszylinders 8 in die Stellung c aufhebt, wobei der Vorderteil des Bügels 5 sich vom Zughaken löst und die Lokomotive damit rückwärts und vom Wagen los gefahren werden kann.When coupling a locomotive to a car with the shunting coupling according to patent 78031, the driver drives the locomotive buffer to bear against the car buffer, with the lever 3 and its bracket 5 being approximately on the horizontal plane are (position b) and the bracket along the inclined upper edge of the hook 1 of the locomotive is brought onto this hook, so that the front part of the bracket falls on the hook. The driver then drops the lever into driving position a by his own weight by means of a working cylinder 8. The hinge point 4 bends between the lever 3 and the bracket 5. The locomotive is in turn uncoupled from the car in that the driver who is in the driver's cab lifts the lever 3 into position c by means of the working cylinder 8 by actuating a pressure valve, the front part of the bracket 5 detaching from the pulling hook and the locomotive can be driven backwards and off the car.

Durch Verwendung der erfindungsgemässe Linienfahrtkupplung wird die Kupplung an dem Zughaken durch derartiges flexibles Pressen des Bügels 5 auf dem Zughaken gesichert, dass im Falle, dass der Abstand zwischen dem Zug und der Lokomotive plötzlich kleiner wird oder der Zug und die Lokomotive z.B. an der Weiche springen, der Bügel und der Hebel 3 unmittelbar in die Stellung a gespannt werden, wobei die Passung der Verkuppelung beibehalten wird.By using the line coupling according to the invention, the coupling on the draw hook is secured by such flexible pressing of the bracket 5 on the draw hook that in the event that the distance between the train and the locomotive suddenly becomes smaller or the train and the locomotive e.g. jump on the switch, the bracket and the lever 3 are immediately stretched into position a, the fit of the coupling being maintained.

Die erfindungsgemässe Funktion verleiht somit dem Bügel 5 und dem Hebel 3 eine flexible Funktion, so dass sie, wenn die Lokomotive zieht, fähig sind sich zu strecken und sich unmittelbar beim Vermindern der Zugkraft die Verkuppelung zurückziehen können.The function according to the invention thus gives the bracket 5 and the lever 3 a flexible function, so that when the locomotive pulls they are able to stretch and the coupling can withdraw immediately when the tractive force is reduced.

Eine solche Funktion kann z.B. durch eine Feder oder durch die mit Druckspeichern versehene Hydraulik oder durch Verwenden von einem Druckluftzylinder als Arbeitzylinder des Hebels 3 erzielt werden, wobei es durch die Erfindung möglich ist die Funktion mittels der Elastizitätseigenschaften der Druckluft zu verwirklichen. Die dazu auf Grund der Gewichte von den Kupplungsteilen 3 und 5 zum Entgegenwirken von Ruck- und Trägheitskräfte benötigte Kraft beträgt etwa 7 kN. Nachfolgend wird die erfindungsgemässe Funktion mit Hilfe eines Druckluftzylinders dargestellt. Dabei wird der Hebel 3 mit Hilfe des sich in der Arbeitstellung befindenden Arbeitszylinders 8 durch den Arretierriegel 10 an dem Zughaken gedrückt.Such a function can be achieved, for example, by a spring or by the hydraulics provided with pressure accumulators or by using a compressed air cylinder as the working cylinder of the lever 3, it being possible for the invention to implement the function by means of the elastic properties of the compressed air. The force required for this due to the weights of the coupling parts 3 and 5 to counteract jerk and inertial forces is approximately 7 kN. Below is the Function according to the invention shown with the aid of a compressed air cylinder. The lever 3 is pressed with the help of the working cylinder 8 in the working position by the locking bolt 10 on the pull hook.

In Fig 2 ist der Arretierriegel 10 zur besseren Anschaulichkeit in bezug auf Fig 1 vergrössert dargestellt. Die Kolbenstange 11 des Arbeitszylinders 8 ist in Fig 2 an dem Hebel 3 durch eine Hebelspindel 12 gekuppelt.In Fig. 2 the locking bar 10 is shown enlarged for clarity with respect to Fig. 1. The piston rod 11 of the working cylinder 8 is coupled to the lever 3 in FIG. 2 by a lever spindle 12.

Der Arretierriegel 10 ist durch einen Bolzen 17 an die Hebelspindel angeschlossen. Die untere Stellung des Hebels 3 in Verhältnis zu der Hebelspindel wird durch eine Schraube 13 justiert. Der Hebel 3 hat zwischen einem Nocken 16 des Arretierriegels und der Verstellschraube 13 einen kleinen Spielraum. In der Fahrtstellung (a) drückt der Nocken 16 den Hebel nach unten, wobei der Bügel 5 an dem Zughaken gepresst bleibt.The locking bolt 10 is connected by a bolt 17 to the lever spindle. The lower position of the lever 3 in relation to the lever spindle is adjusted by a screw 13. The lever 3 has a small margin between a cam 16 of the locking bar and the adjusting screw 13. In the travel position (a), the cam 16 presses the lever down, the bracket 5 remaining pressed on the pull hook.

Wenn man den Hebel 3 in die Vertikalstellung (d) heben möchte, z.B. beim Kuppeln der Lokomotive für eine längere Zeit an einem mit Zentralpuffer versehenen Wagen, wird der Arretierriegel 10 in die Stellung "offen" gedreht, wobei der Nocken 16 des Hebels sich aus dem Wege des Hebels dreht. Der Arretierriegel kann einen rohrartigen Ausbau 18 haben, an welchem z.B. der arretierende Zapfen (d) des Hebels in der Vertikalstellung placiert werden kann. Dieser Zapfen hält den Arretierriegel in der Stellung "offen" wenn der Hebel 3 mit der Hand an der Verriegelungsgabel gehoben wird.If you want to lift the lever 3 to the vertical position (d), e.g. when coupling the locomotive for a long time on a car provided with a central buffer, the locking bar 10 is turned to the "open" position, the cam 16 of the lever rotating out of the way of the lever. The locking bar can have a tubular extension 18, on which e.g. the locking pin (d) of the lever can be placed in the vertical position. This pin holds the locking bar in the "open" position when the lever 3 is lifted by hand on the locking fork.

Wenn die Lokomotive an einem mit Zughaken ausgerüsteten Wagen gekuppelt wird, garantiert die erfindungsgemässe Lösung, dass z.B. beim Ziehen des Schnellzuges entstandene schnelle Rucke und Trägheitskräfte nicht im Stande sind, ein Lösen des Bügels 5 vom Zughaken zu verursachen. Neben der Tatsache, dass der Bügel im Zughaken sicherer gehalten wird, vermindert die Erfindung ebenfalls Rucke und Stösse zwischen der Lokomotive und dem Wagen und damit auch Bewegungsverrückungen in bezug auf andere Wagen. Die erfindungsgemässe Kupplung ermöglicht das Kuppeln einer Lokomotive an einem mit Zughaken ausgerüsteten Wagen aber auch an einem Wagen, der mit Zentralpuffer ausgerüstet ist, weil der Hebel, der an dem Zughaken gekuppelt wird, an dem Zentralpuffer der Lokomotive gelagert ist.If the locomotive is coupled to a car equipped with a pull hook, the solution according to the invention guarantees that, for example, rapid jerks and inertial forces which occur when the fast train is being pulled are not able to cause the bracket 5 to be released from the pull hook. In addition to the fact that the bracket is held more securely in the draw hook, the invention also reduces jerks and bumps between the locomotive and the wagon, and thus also movement movements with respect to other cars. The coupling according to the invention enables a locomotive to be coupled to a car equipped with a pull hook, but also to a car equipped with a central buffer, because the lever which is coupled to the pull hook is mounted on the central buffer of the locomotive.

Beim Kuppeln einer Lokomotive an einem mit Zentralpuffer ausgerüsteten Wagen wird der Hebel 3 in die Vertikalstellung d gehoben oder der Bügel in die untere Stellung e heruntergesenkt, wobei er sich nicht im Wege der Verkuppelung befindet. Das Schloss des Zentralpuffers wird durch einen Membranzylinder 19 geöffnet, welcher sich im Unterteil der Kupplung befindet.When coupling a locomotive to a car equipped with a central buffer, the lever 3 is raised to the vertical position d or the bracket is lowered to the lower position e, whereby it is not in the way of the coupling. The lock of the central buffer is opened by a membrane cylinder 19, which is located in the lower part of the clutch.

Zu den Vorrichtungen dieser Kupplungen gehört ein elektrisches Steuerungssystem, dessen Steuerungsdrucktastengehäuse in der Fahrerkabine der Lokomotive placiert ist.The devices of these couplings include an electrical control system, the control push button housing of which is placed in the driver's cabin of the locomotive.

Obwohl die Erfindung in Verbindung mit VAPITI-Kupplungen erklärt worden ist, kann sie natürlich im Rahmen der Patentansprüche auch in anderen Zusammenhängen angewendet werden.Although the invention has been explained in connection with VAPITI couplings, it can of course also be used in other contexts within the scope of the claims.
