Description

Die Erfindung betrifft einen Kupplungskopf einer Mittelpufferkupplung mit einer elektrischen Heizung nach dem Oberbegriff des Anspruchs 1.The invention relates to a coupling head a central buffer coupling with an electric heater according to the preamble of claim 1.

Bei S- Bahn- Triebzügen der Baureihe ET 420 sind Mittelpufferkupplungen im Einsatz gewesen, bei denen in die Pufferfläche des Kupplungskopfes im Bereich des Zentrierkegels und des Einlaufrichters eine etwa halbkreisförmige Nut eingebracht ist, in die ein elektrischer Heizkörper eingelegt ist. Der Heizkörper soll im Winter die Stirnfläche und den Kupplungsmechanismus von Eis und Schnee freihalten und die Kupplungsfunktion sicherstellen. Die Nut ist durch ein Hartlot, das einen Teil der Pufferfläche bildet, nach außen abgeschlossen. Als Hartlote können nur niedrig schmelzende Hartlote, z. B. teure Silberlote, verwendet werden, weil bei höheren Verarbeitungstemperaturen die Gefahr der Beschädigung des Heizkörpers besteht. Der Einsatz von Weichloten mit niedrigerem Schmelzpunkt erwies sich als ungeeignet, da bei der benötigten Heizleistung die Schmelztemperatur des Weichlotes erreicht werden konnte. Beim Einlöten von Heizkörpers besteht immer die Gefahr einer örtlichen Überhitzung und damit der Zerstörung des Heizkörpers vor Inbetriebnahme. Auch ist ein Einlöten des Heizkörpers ohne Hohlräume im Füllmaterial nur mit erheblichem Aufwand sicherzustellen. In den zu vermeidenden Hohlräumen kann es einerseits zu örtlichen Überhitzungen des Heizkörpers kommen oder andererseits kann im Betrieb Feuchtigkeit eindringen, was zu Korrosionen führt.In S-Bahn trainsets of the ET 420 series are central buffer couplings have been used in which in the buffer surface of the coupling head in the area of the centering cone and the inlet funnel one approx Semicircular groove is inserted, into which an electric radiator is inserted. The radiator should in winter the face and the Clutch mechanism of ice and snow clear and the Ensure coupling function. The groove is through a braze, the one Part of the buffer surface forms, closed to the outside. As brazing alloys can only low melting brazing, z. Expensive silver solders, be used because at higher processing temperatures the There is danger of damaging the radiator. The use of Soft melts with a lower melting point proved to be unsuitable because at the required heating power, the melting temperature of the Soft solder could be achieved. When soldering radiator There is always the risk of local overheating and thus of the Destruction of the radiator before commissioning. Also is a soldering of the Radiator without cavities in the filler only with considerable To ensure effort. In the cavities to avoid it can on the one hand come to local overheating of the radiator or other can penetrate moisture during operation, resulting in corrosion leads.

Weiter ist es bekannt, die Nut in der Stirnplatte, in die der Heizkörper eingelegt ist, durch eingeschweißte oder eingelötete Abdeckbleche nach außen abzudeckeken. Durch die erhöhte Wärmezufuhr beim Schweißen oder Löten muss ein möglicher Verzug oder eine Veränderung der Materialeigenschaften der Abdeckbleche als auch der Stirnplatte beachtet und berücksichtigt werden. Da die Nut aus Montagegründen deutlich breiter als der Durchmesser des Heizkörpers gefertigt ist, gibt es undefinierte Anlagen desselben an der Innenseite der Nut, was zu Wärmestau und Überhitzungen und als Folge zur Zerstörung des Heizkörpers führen kann. Neben der möglichen Beschädigung des eingelegten Heizkörpers durch das Schweiß-/Lötverfahren selbst ist im Hohlraum für den Heizkörper immer die Gefahr des Eindringens von Feuchtigkeit und damit der Zerstörung des Heizkörpers gegeben.Next, it is known, the groove in the face plate, in which the radiator is inserted by welded or soldered cover plates to cover the outside. Due to the increased heat during the Welding or soldering must be a possible delay or a Changing the material properties of the cover plates as well the face plate are considered and taken into account. Because the groove out Installation reasons significantly wider than the diameter of the radiator is made, there are undefined systems of the same on the inside the groove, resulting in heat accumulation and overheating and as a result to Destruction of the radiator may result. In addition to the possible Damage to the inserted radiator due to the welding / soldering process even in the cavity for the radiator is always the danger the ingress of moisture and thus the destruction of the Radiator given.

Aus der DE 296 11 148 U ist eine elektrische Heizung für Mittelpufferkupplungen bekannt, deren Heizkörper in der Nut mit Silikonwerkstoff verfüllt ist, der die äußere Abdeckung bildet und der bei der Verfüllung ein fließfähiger Einkomponentenwerkstoff ist, welcher unter Einwirkung von Luftfeuchtigkeit bei Raumtemperatur vernetzt und aushärtet. Aufgrund der relativ schlechten Wärmeleitfähigkeit λ = 0,21 W/(m x K) und der schlechten Temperaturbeständigkeit der bislang erhältlichen und eingesetzten, elastischen Vergußmassen kann es zu einer Überhitzung des Heizkörpers kommen, die zur Zerstörung der Vergußmasse und als Folge zur Zerstörung der Heizkörpers führt. Auch besteht bei der geringen Oberflächenfestigkeit derartiger Vergußmassen die Gefahr des Eindringens von Fremdkörpern und damit der mechanischen Beschädigung des Heizkörpers.From DE 296 11 148 U is an electric heater for Central buffer couplings known whose radiator in the groove with Silicone material is filled, which forms the outer cover and at the backfilling is a flowable one-component material, which crosslinked under the influence of humidity at room temperature and cures. Due to the relatively poor thermal conductivity λ = 0.21 W / (m × K) and the poor temperature resistance of the past available and used, elastic sealing compounds may be a Overheating of the radiator come to the destruction of the Potting compound and as a result leads to the destruction of the radiator. Also exists with the low surface strength of such Vergußmassen the risk of penetration of foreign bodies and thus mechanical damage of the radiator.

Weiterhin ist bei den vorgenannten Bauarten nachteilig, dass ein Austausch defekter Heizkörper, im allgemeinen werden Rohrwendelheizkörper verwendet, nur durch eine aufwendige Trennung der Lötnähte bzw. der Vergußmasse im Herstellerwerk bzw. in einer Werkstatt möglich ist. Nach Austausch defekter Heizkörper müssen die verwendeten Systeme durch erneutes Einlöten/Einschweißen oder Vergießen wieder aufwändig hergestellt werden.Furthermore, it is disadvantageous in the aforementioned types that a Exchange defective radiators, in general Rohrwendelheizkörper used, only by a complex separation the solder joints or the potting compound in the factory or in a Workshop is possible. After replacing defective radiators must the used systems by re-soldering / welding or Pouring back to be elaborately made.

Der Erfindung liegt daher die Aufgabe zugrunde, eine elektrische Heizung für den Kupplungskopf einer Mittelpufferkupplung derart auszubilden, dass der Wärmeübergang vom Heizkörper in den Kupplungskopf verbessert und der Aufwand zur Montage und Demontage des Heizkörpers verringert ist.The invention is therefore based on the object, an electrical Heater for the coupling head of a central buffer coupling such Form that the heat transfer from the radiator in the Coupling head improves and the effort for assembly and Disassembly of the radiator is reduced.

In the coupling head 1 shown in Fig. 1 a Central buffer coupling are in its front plate recesses in Formation of grooves arranged. The grooves are in different Orientations and distance dimensions introduced into the face plate and towards the front in the plane of the end plate closure by end plates 2 Coverable or covered. The end plates 2 are adapted Lowered and connected to the face plate, preferably by brazing. The resulting Recessed / grooves are provided for receiving radiators 3 and are perfectly fitting in terms of their cross-sectional dimension coordinated. Each heater 3 is after insertion via a retaining plate 4 on the coupling head 1 by means of releasable fastening means 5 fixable and thus mounted and demortierbar. It is essential that the sensitive radiator 3 still after the Insertion of the end plate 2 can be introduced into the coupling body, whereby the risk of damaging the used radiator 3 and their supply lines in the manufacturing process of the central buffer coupling is significantly reduced.

Die Ausnehmungen sind wie vorstehend beschrieben vorzugsweise als Nut in der Stirnplatte ausgebildet, die nach vorn mittels eines eingefügten Stirnbleches 2 abgedeckt ist. Die Ausnehmungen sind jedoch auch als Bohrung ausbildbar, wodurch zwar das Einfügen von Stirnblechen 2 entfällt, jedoch nicht unerhebliche Probleme bei der Spanabfuhr und beim Bohren in gehärteten und vergüteten Stählen zu lösen sind.The recesses are preferably as described above Groove formed in the face plate, the forward by means of a inserted front plate 2 is covered. The recesses are However, as a hole ausbildbar, whereby the insertion of Front plates 2 deleted, but not insignificant problems in the Chip removal and drilling in hardened and tempered steels too are solved.

Nach heutigem Stand der Technik werden bisher Rohrwendelheizkörper in verschiedenen Formen in unterschiedlichen Längen und Abmessungen in Nuten eingelegt, wobei die Nuten im Regelfall mindestens bereichsweise nicht linear ausgeführt sind. Die Nutenbreite wird wegen der Maßtoleranzen beim Biegen der Rohrwendelheizkörper etwa doppelt so groß wie der Heizkörper ausgeführt. Durch die nunmehrige Verwendung von aufeinander abgestimmten, passgenauen Durchmessern von Ausnehmung/Nut/Bohrung werden undefinierte und ungestützte Anlagen des Heizkörpers in der Ausnehmung/Nut/Bohrung und örtlich erheblich voneinander abweichende Wärmeleitwerte vermieden. Eine lineare Ausbildung des Heizkörpers und die diesen aufnehmende Ausnehmung/Nut/Bohrung erleichtert bzw. ermöglicht das Einbringen von Heizkörpern nach mechanischer Fertigstellung des Kupplungskopfes. Die vorgesehene lösbare Besfestigung des Heizkörpers 3 ermöglicht eine schnelle Montage und Demontage.According to the current state of the art Rohrwendelheizkörper so far in different shapes in different lengths and Dimensions inserted in grooves, with the grooves as a rule at least partially non-linear. The groove width is because of the dimensional tolerances in bending the tube helical radiator about twice the size of the radiator. By the now use of coordinated, accurately fitting Diameters of recess / groove / bore undefined and unsupported installations of the radiator in the Recess / groove / bore and locally significantly different from each other deviating thermal conductivity values avoided. A linear education of the Radiator and this receiving recess / groove / bore facilitates or allows the introduction of radiators after Mechanical completion of the coupling head. The intended releasable Besfestigung the radiator 3 allows quick installation and disassembly.
