Description

Kupplungselement für ein Bremssystem eines Schienenfahrzeugs, Bremssystem mit einem solchen Kupplungselement und Schienenfahrzeug mit einem solchen Bremssystem Coupling element for a braking system of a rail vehicle, braking system with such a coupling element and rail vehicle with such a braking system
Die Erfindung betrifft ein Kupplungselement für ein Bremssystem eines Schienenfahrzeugs, ein Bremssystem mit einem solchen Kupplungselement und ein Schienenfahrzeug mit einem solchen Bremssystem, das insbesondere in Umgebungen mit einem hohen Schmutzpartikelanteil in der Umgebungsluft eingesetzt wird. The invention relates to a coupling element for a braking system of a rail vehicle, a braking system with such a coupling element and a rail vehicle with such a braking system, which is used in particular in environments with a high proportion of dirt particles in the ambient air.
Oftmals werden Bremsleitungen eines Bremssystems eines Schienenfahrzeugs, beispielsweise einer Lokomotive oder eines Wagens, bei einem Abstellen nicht ordnungsgemäß verschlossen, da es erforderlich sein kann, dass noch Druckluft aus dem Bremssystem abgelassen werden muss. Dabei besteht jedoch die Gefahr, dass die Bremsleitungen länger unverschlossen bleiben, wodurch dann Schmutzpartikel in die Bremsleitungen eintreten können. Diese können dann bei einer nächsten Inbetriebnahme beispielsweise in Bremsaktuatoren gelangen und diese dadurch beschädigen oder einen höheren Verschleiß verursachen. Brake lines of a braking system of a rail vehicle, for example a locomotive or a wagon, are often not closed properly when the vehicle is parked, since it may be necessary for compressed air to be released from the braking system. However, there is a risk that the brake lines will remain unclosed for a longer period of time, as a result of which dirt particles can then enter the brake lines. These can then get into brake actuators, for example, during the next start-up and thereby damage them or cause greater wear.
Darüber hinaus kann bei dem Ablassen der Druckluft aus dem Bremssystem die Geschwindigkeit der austretenden Luft sehr hoch sein, wodurch zum einen ein sehr lautes Geräusch entstehen kann und zum anderen ein Schlauch an einem Ende der Bremsleitung unkontrollierte Bewegungen ausführen kann. In addition, when the compressed air is released from the brake system, the speed of the escaping air can be very high, which can make a very loud noise and cause a hose at one end of the brake line to make uncontrolled movements.
Ferner kann es aufgrund von Vorschriften erforderlich sein, dass eine Hauptluftleitung des Bremssystems auch während des Betriebs offen sein muss, sodass auch hier wiederum Schmutzpartikel aus der Umgebungsluft in die Bremsleitung eintreten können. Furthermore, regulations may require that a main air line of the brake system must also be open during operation, so that dirt particles from the ambient air can enter the brake line here as well.
Der Erfindung liegt die Aufgabe zugrunde, die obigen Probleme auszuräumen und ein Kupplungselement, ein Bremssystem und ein Schienenfahrzeug bereitzustellen, die ohne großen Aufwand einen zuverlässigen und vorschriftsgemäßen Einsatz ermöglichen. The invention has for its object to eliminate the above problems and to provide a coupling element, a braking system and a rail vehicle that enable reliable and proper use without great effort.
Die Aufgabe wird durch ein Kupplungselement gemäß Anspruch 1 , ein Bremssystem gemäß Anspruch 6 und ein Schienenfahrzeug gemäß Anspruch 7 gelöst. Vorteilhafte Weiterentwicklungen sind in den abhängigen Ansprüchen enthalten. The object is achieved by a coupling element according to claim 1, a braking system according to claim 6 and a rail vehicle according to claim 7. Advantageous further developments are contained in the dependent claims.
Gemäß einem Aspekt der Erfindung weist ein Kupplungselement für ein Bremssystem eines Schienenfahrzeugs einen Kupplungsbereich auf, der dazu ausgebildet ist, an einem Kupplungskopf, der an einer Bremsleitung des Bremssystems vorgesehen ist, ankuppelbar zu sein. Ferner weist das Kupplungselement ein Filterelement auf, das dazu ausgebildet ist, Luft durch das Kupplungselement von dem ankuppelbaren Kupplungskopf durch das Filterelement strömen zu lassen und die durch das Filterelement strömende Luft zu filtern. According to one aspect of the invention, a coupling element for a braking system of a rail vehicle has a coupling area which is designed to be able to be coupled to a coupling head which is provided on a brake line of the braking system. Furthermore, the coupling element has a filter element which is designed to allow air to flow through the coupling element from the coupler coupling head through the filter element and to filter the air flowing through the filter element.
Durch das Filtern mittels des Filterelements kann einfach verhindert werden, dass, in einem Zustand, in dem das Kupplungselement an dem Kupplungskopf angekuppelt ist, Schmutzpartikel aus der Umgebungsluft in die Bremsleitung und bei einem weiteren Betrieb in Aktoren des Bremssystems gelangen und diese beschädigen oder einen Verschleiß davon erhöhen. Damit kann die Zuverlässigkeit des Bremssystems verbessert werden. Filtering by means of the filter element makes it easy to prevent, in a state in which the coupling element is coupled to the coupling head, dirt particles from the ambient air from getting into the brake line and, during further operation, into actuators of the brake system and damaging them or causing wear increase of it. The reliability of the braking system can thus be improved.
In einer vorteilhaften Ausgestaltung des Kupplungselements ist das Filterelement dazu ausgebildet, eine Geschwindigkeit der durch das Filterelement strömenden Luft zu verringern, um eine Geräuschentwicklung der durch das Kupplungselement strömenden Luft zu verringern. In an advantageous embodiment of the coupling element, the filter element is designed to reduce the speed of the air flowing through the filter element in order to reduce the noise generated by the air flowing through the coupling element.
Durch diese Eigenschaft ist es möglich, eine störende, und unter ungünstigen Umständen sogar gesundheitsschädliche, Geräuschentwicklung bei einem Öffnen eines Kupplungshahns zu eliminieren, sodass ein geräuschemissionsärmerer und ungefährlicher Betrieb möglich ist. Zusätzlich wird der Vorteil erzielt, eine Unfallgefahr zu reduzieren, insbesondere da durch die verringerte Strömungsgeschwindigkeit auch ein mögliches gefährliches unkontrolliertes Bewegen eines Schlauches am Ende der Bremsleitung verhindert wird wenn Luft beim Ablassen von Druck mit zu hoher Geschwindigkeit austritt. This property makes it possible to eliminate a disturbing, and under unfavorable circumstances even harmful, noise development when opening a coupling tap, so that less noisy and safer operation is possible. In addition, the advantage is achieved to reduce the risk of accidents, especially since the reduced flow rate and a possible dangerous uncontrolled movement of a hose at the end of the brake line is prevented if air escapes at too high a speed when the pressure is released.
Bei einer weiteren vorteilhaften Ausgestaltung weist das Kupplungselement ein Befestigungselement auf, das dazu ausgebildet ist, beweglich mit dem Schienenfahrzeug verbunden zu werden. In a further advantageous embodiment, the coupling element has a fastening element which is designed to be movably connected to the rail vehicle.
Durch diese Eigenschaft des Kupplungselements können neben starren Bremsleitungen auch bewegliche Bremsschläuche einfach verschlossen werden, und darüber hinaus kann ein Bewegungsbereich eines Endes des Bremsschlauchs so eingegrenzt werden, dass einerseits ein Herabhängen auf den Boden und andererseits eine unkontrollierte größere Bewegung verhindert werden können. This property of the coupling element means that, in addition to rigid brake lines, flexible brake hoses can also be easily closed, and moreover, a movement range of one end of the brake hose can be limited in such a way that, on the one hand, hanging down on the ground and, on the other hand, uncontrolled larger movements can be prevented.
Gemäß einer anderen vorteilhaften Ausgestaltung des Kupplungselements weist es ein Befestigungselement auf, das dazu ausgebildet ist, starr mit dem Schienenfahrzeug verbunden zu werden. According to another advantageous embodiment of the coupling element, it has a fastening element that is designed to be rigidly connected to the rail vehicle.
Somit besteht die Möglichkeit, dass ein Schlauch am Ende der Bremsleitung einfach mit einer Hand mit dem Kupplungselement verbunden werden kann, da es nicht notwendig ist, das Kupplungselement zum Ankuppeln mit der anderen Hand festzuhalten. Durch die starre Verbindung wird auch das Ende des Schlauchs an einem definierten Platz festgehalten. Thus, there is the possibility that a hose at the end of the brake line can be easily connected to the coupling element with one hand, since it is not necessary to hold the coupling element with the other hand for coupling. Due to the rigid connection, the end of the hose is also held in a defined place.
Gemäß einer weiteren vorteilhaften Ausgestaltung des Kupplungselements ist das Filterelement in Strömungsrichtung der Luft an einer Seite zur Umgebung hin offen und dazu ausgebildet, die durch das Filterelement strömende Luft in die Umgebung strömen zu lassen. According to a further advantageous embodiment of the coupling element, the filter element is open on one side to the environment in the flow direction of the air and is designed to allow the air flowing through the filter element to flow into the environment.
Bei dieser Ausgestaltung ist es einfach möglich, die Bremsleitung über das Kupplungselement zu entlüften. In weiteren vorteilhaften Ausgestaltungen des Kupplungselements weist das Filterelement ein Geflecht, insbesondere ein Drahtgeflecht, und/oder weiterhin eine Prallkammer und/oder eine Prallwand auf. With this configuration, it is easily possible to bleed the brake line via the coupling element. In further advantageous configurations of the coupling element, the filter element has a mesh, in particular a wire mesh, and/or an impact chamber and/or an impact wall.
Gemäß weiteren Aspekten der Erfindung enthält ein Bremssystem ein Kupplungselement und ein Schienenfahrzeug ein Bremssystem wie oben ausgeführt, wodurch die zuvor genannten Vorteile erzielt werden können. According to further aspects of the invention, a braking system contains a coupling element and a rail vehicle contains a braking system as set out above, as a result of which the aforementioned advantages can be achieved.
In einer vorteilhaften Ausgestaltung weist das Schienenfahrzeug das Kupplungselement mit dem oben erläuterten beweglich befestigbaren Befestigungselement auf, sowie ein eigenes bewegliches Verbindungselement, wobei sowohl starre Bremsleitungen als auch ein Bremsschlauch durch das Kupplungselement verschlossen werden können. Ferner kann ein Bewegungsbereich eines Bremsschlauchs am Ende der Bremsleitung so eingegrenzt werden kann, dass einerseits ein Herabhängen auf den Boden und andererseits eine unkontrollierte größere Bewegung verhindert werden kann. In an advantageous embodiment, the rail vehicle has the coupling element with the movably attachable fastening element explained above, as well as its own movable connecting element, with both rigid brake lines and a brake hose being able to be closed by the coupling element. Furthermore, a range of movement of a brake hose at the end of the brake line can be limited in such a way that, on the one hand, hanging down on the ground and, on the other hand, an uncontrolled larger movement can be prevented.
In einer anderen vorteilhaften Ausgestaltung des Schienenfahrzeugs enthält es ein Bremssystem mit einem Bremsschlauch zumindest am Ende der Bremsleitung und das Kupplungselement ist dazu ausgebildet, starr mit dem Schienenfahrzeug verbunden zu werden, wodurch es möglich ist, dass der Bremsschlauch am Ende der Bremsleitung einfach mit einer Hand mit dem Kupplungselement verbunden werden kann und dessen Ende an einem definierten Platz festgehalten wird. In another advantageous embodiment of the rail vehicle, it contains a brake system with a brake hose at least at the end of the brake line and the coupling element is designed to be rigidly connected to the rail vehicle, which makes it possible for the brake hose at the end of the brake line to be easily removed with one hand can be connected to the coupling element and the end of which is held in a defined place.
Nachstehend wird die Erfindung anhand von Ausführungsbeispielen unter Bezugnahme auf die beigefügten Zeichnungen erläutert. The invention is explained below by means of exemplary embodiments with reference to the accompanying drawings.

Fig. 2 is a partially sectioned side view of the coupling element of Fig. 1 coupled to a coupling head. Fig. 1 shows a section of a braking system 1 of a rail vehicle 2 with a coupling element 3 coupled to a coupling head 4, and Fig. 2 shows a partially sectioned side view of the coupling element 3 coupled to the coupling head 4.
Das Kupplungselement 3 weist einen Kupplungsbereich 5 auf, der dazu ausgebildet ist, an einem Kupplungskopf 4 einer Bremsleitung 10 ankuppelbar zu sein. Ankuppelbar bedeutet in diesem Zusammenhang, dass der Kupplungsbereich 5 mit einem Kupplungsbereich des Kupplungskopfs 4 über einen Bajonettverschluss eine formschlüssige Verbindung eingeht und ihn verschließt. Darüber hinaus ist der Kupplungsbereich 5 mit dem Kupplungskopf 4 so verbunden, dass eine Dichtigkeit der Verbindung mittels einem elastischen Dichtung sichergestellt ist. In alternativen Ausführungsformen kann auch eine andersartige formschlüssige Verbindung, beispielsweise, wie bei industriellen Druckluftanlagen über in Nuten einrastende Kugeln und/oder eine Labyrinthdichtung vorgesehen sein. In anderen alternativen Ausführungsformen ist keine separate Dichtung vorgesehen und der Kupplungskopf 4 ist nicht abdichtend verschlossen. The coupling element 3 has a coupling area 5 which is designed to be able to be coupled to a coupling head 4 of a brake line 10 . In this context, can be coupled means that the coupling area 5 enters into a form-fitting connection with a coupling area of the coupling head 4 via a bayonet lock and closes it. In addition, the coupling area 5 is connected to the coupling head 4 in such a way that the tightness of the connection is ensured by means of an elastic seal. In alternative embodiments, a different form-fitting connection can also be provided, for example, as in industrial compressed air systems via balls locking into grooves and/or a labyrinth seal. In other alternative embodiments, no separate seal is provided and the coupling head 4 is not sealed.
Der Kupplungskopf 4 ist mit der Bremsleitung 10 der Bremsanlage 1 verbunden. Die Bremsleitung 10 ist in der gezeigten Ausführungsform ein Bremsschlauch, kann alternativ aber durch ein starres Rohr ausgebildet sein. The coupling head 4 is connected to the brake line 10 of the brake system 1. The brake line 10 is a brake hose in the embodiment shown, but can alternatively be formed by a rigid tube.
Ferner weist das Kupplungselement 3 ein Filterelement 6 auf, das in Fig. 2 gezeigt ist. Das Filterelement 6 dient dazu, Luft aus der Bremsleitung 10 in die Umgebung 9 ausströmen zu lassen und filtert durch das Filterelement 6 strömende Luft. Ferner ist das Filterelement 6 so ausgestaltet, dass die Geschwindigkeit der durch das Filterelement 6 strömenden Luft verringert wird. Dadurch wird eine Geräuschentwicklung aufgrund der durch das Filterelement 6 strömenden Luft reduziert. In einer alternativen Ausführungsform ist das Filterelement 6 nur mit der Filterfunktion ausgestattet, so dass die durch das Filterelement 6 strömende Luft lediglich gefiltert wird, ohne dass ihre Geschwindigkeit wesentlich verringert wird. Das Filterelement 6 hat darüber hinaus die weitere Funktion, dass dadurch verhindert wird, dass in dem Zustand, in dem der Kupplungskopf 4 an das Kupplungselement 3 gekuppelt ist, Schmutzpartikel in den Kupplungskopf 4 und die Bremsleitung 10 eindringen. Das Filterelement 6 weist ein Geflecht, insbesondere ein Drahtgeflecht, auf. In alternativen Ausführungsformen weist das Filterelement 6 alternativ oder zusätzlich eine Prallkammer und/oder eine Prallwand auf. Furthermore, the coupling element 3 has a filter element 6, which is shown in FIG. The filter element 6 serves to allow air to flow out of the brake line 10 into the environment 9 and filters air flowing through the filter element 6 . Furthermore, the filter element 6 is designed in such a way that the speed of the air flowing through the filter element 6 is reduced. As a result, the development of noise due to the air flowing through the filter element 6 is reduced. In an alternative embodiment, the filter element 6 is only provided with the filter function, so that the air flowing through the filter element 6 is only filtered without its velocity being significantly reduced. The filter element 6 also has the additional function of preventing that in the state in which the coupling head 4 is coupled to the coupling element 3, dirt particles penetrate into the coupling head 4 and the brake line 10. The filter element 6 has a mesh, in particular a wire mesh. In alternative embodiments, the filter element 6 alternatively or additionally has an impact chamber and/or an impact wall.
Das Kupplungselement 3 weist einen Fortsatz 7 als ein Befestigungselement auf, mittels dem das Kupplungselement 3 mit dem Schienenfahrzeug 2, insbesondere an seinen Enden, an denen die Kupplungsköpfe 5 üblicherweise angeordnet sind, verbunden werden kann. The coupling element 3 has an extension 7 as a fastening element, by means of which the coupling element 3 can be connected to the rail vehicle 2, in particular at its ends where the coupling heads 5 are usually arranged.
In der gezeigten Ausführungsform weist das Kupplungselement 3 ferner eine Öse 8 als das Befestigungselement auf, mittels der es über ein bewegliches Verbindungselement, beispielsweise eine Kette (nicht gezeigt), beweglich mit dem Schienenfahrzeug 2 verbunden werden kann. In der vorliegenden Ausführungsform befindet sich die Öse 8 am Ende des Fortsatzes 7. In alternativen Ausführungsformen weist das Kupplungselement 3 keine Öse 8 in dem Fortsatz 7 auf, sondern beispielsweise einfach eine Bohrung und/oder das Kupplungselement 3 ist über ein Stahlseil mit dem Schienenfahrzeug 2 verbunden. Das beweglich mit dem Schienenfahrzeug 2 verbundene Kupplungselement 3 kann sowohl mit einer starren Bremsleitung 10 als auch mit einem Bremsschlauch zumindest am Ende der Bremsleitung 10 verwendet werden. In the embodiment shown, the coupling element 3 also has an eyelet 8 as the fastening element, by means of which it can be movably connected to the rail vehicle 2 via a movable connecting element, for example a chain (not shown). In the present embodiment, the eyelet 8 is located at the end of the extension 7. In alternative embodiments, the coupling element 3 has no eyelet 8 in the extension 7, but simply a bore and/or the coupling element 3 is connected to the rail vehicle 2 via a steel cable tied together. The coupling element 3, which is movably connected to the rail vehicle 2, can be used both with a rigid brake line 10 and with a brake hose, at least at the end of the brake line 10.
In einer alternativen Ausführungsform ist das Kupplungselement 3 dazu ausgebildet, starr, beispielsweise mittels Anschrauben, mit dem Schienenfahrzeug 2 verbunden zu werden. Das Kupplungselement 3 mit einer starren Verbindung zu dem Schienenfahrzeug 2 ist nicht für ein Ankuppeln an einen Kupplungskopf 5 an einer starren Bremsleitung 10 geeignet, sondern nur für flexible Bremsschläuche mit dem Kupplungskopf 5 an einem Ende der Bremsleitung 10. In an alternative embodiment, the coupling element 3 is designed to be rigidly connected to the rail vehicle 2, for example by means of screws. The coupling element 3 with a rigid connection to the rail vehicle 2 is not suitable for coupling to a coupling head 5 on a rigid brake line 10, but only for flexible brake hoses with the coupling head 5 at one end of the brake line 10.
