Description

Die Erfindung betrifft einen Kupplungskopf für Schienenfahrzeuge nach dem Oberbegriff des Anspruchs 1.The invention relates to a coupling head for rail vehicles according to the preamble of claim 1.

Bei Schienenfahrzeugen werden heutzutage vermehrt vollautomatische Kupplungsköpfe eingesetzt. Dabei wird sowohl der mechanische Kupplungsvorgang wie auch das Verbinden der elektrischen sowie der pneumatischen Verbindungs- und/oder Bremsleitungen vollautomatisch, d.h. ohne manuelles Zutun durchgeführt. Auch der Entkupplungsvorgang läuft im allgemeinen vollautomatisch ab.In rail vehicles nowadays increasingly fully automatic coupling heads are used. In this case, both the mechanical coupling process as well as the connection of the electrical and the pneumatic connecting and / or brake lines fully automatically, i. done without manual intervention. The uncoupling process also generally proceeds fully automatically.

Gattungsgemässe Kupplungsköpfe kommen insbesondere bei Mittelpufferkupplungen, beispielsweise bei sogenannten Laschentyp-Kupplungen zum Einsatz und weisen einen Kupplungskopf auf, dessen Stirnplatte mit zumindest einer runden Zentrieröffnung versehen ist. Neben der Zentrieröffnung ist im allgemeinen eine Zentriererhebung in der Form einer Zentrierkuppe angeordnet. Bei den nach dem Stand der Technik ausgebildeten Kupplungsköpfen wird die Zentrierkuppe mittels einer Schweissverbindung an der Stirnplatte befestigt, indem sie in eine dafür vorgesehene Öffnung eingesetzt und danach von der Rückseite der Stirnplatte mittels mehrerer Schweisspunkte fixiert wird. Die Zentrierkuppe steht über die Stirnplatte vor. Beim Kupplungsvorgang dringt die jeweilige Zentrierkuppe in die Zentrieröffnung des Kupplungskopfs der Gegenkupplung ein, wodurch die beiden Kupplungsköpfe aufeinander ausgerichtet werden.Generic coupling heads are used in particular in central buffer couplings, for example in so-called lug-type couplings for use and have a coupling head, the end plate is provided with at least one round centering. In addition to the centering a Zentrierhebung is generally arranged in the form of a Zentrierkuppe. In the prior art coupling heads, the centering tip is fixed to the face plate by means of a welded connection by inserting it into an opening provided for this purpose and then fixing it from the rear side of the face plate by means of a plurality of welding points. The Zentrierkuppe protrudes over the front plate. During the coupling process, the respective Zentrierkuppe penetrates into the centering opening of the coupling head of the counter-coupling, whereby the two coupling heads are aligned.

Als mechanisches Verbindungsteil ist bei den bekannten Kupplungsköpfen ein Verriegelungselement vorgesehen, das einen um eine vertikale Achse verdrehbaren Riegel aufweist. Der zwischen einer Ausgangs- und einer Wirkstellung verdrehbare Riegel ist auf einer Seite mit einer Ausnehmung versehen, während auf der anderen Seite eine Zugstange drehbar angeordnet ist, die zum formschlüssigen Angreifen an dem Riegel der Gegenkupplung ausgebildet ist. Die Kupplung bildet eine Art Parallelogramm, indem im gekuppelten Zustand die beiden Zugstangen parallel verlaufen und die Zugstange der einen Kupplung in die Ausnehmung des Riegels der Gegenkupplung eingreift und umgekehrt. Um die Kupplung zu lösen, d.h. zu entkuppeln, muss der eine Riegel um einen bestimmten Winkel, beispielsweise ca. 45° in eine vorbestimmte Richtung verdreht werden, damit der Formschluss zwischen der Zugstange und dem jeweiligen Riegel aufgehoben wird. Da die beiden Riegel über die Zugstangen miteinander gekoppelt sind, dreht sich beim Verdrehen des einen Riegels der andere Riegel automatisch mit, so dass durch Verdrehen des einen Riegels der Kraftschluss zwischen der jeweiligen Zugstange und dem Riegel der Gegenkupplung aufgehoben wird und die Kupplung damit gelöst ist.As a mechanical connection part a locking element is provided in the known coupling heads, which has a rotatable about a vertical axis latch. The rotatable between a starting and a working position latch is provided on one side with a recess, while on the other side a pull rod is rotatably arranged, which is designed for positive engagement with the latch of the counter-coupling. The coupling forms a kind of parallelogram in that in the coupled state, the two tie rods run parallel and the pull rod of a coupling engages in the recess of the bolt of the counter-coupling and vice versa. To disengage the clutch, ie to decouple, the one bar must be rotated by a certain angle, for example, about 45 ° in a predetermined direction, so that the positive connection between the Pull rod and the respective bolt is canceled. Since the two bars are coupled to each other via the tie rods, the other latch automatically rotates when turning the one bolt, so that the adhesion between the respective tie rod and the latch of the counter-coupling is released by turning the one bolt and the clutch is thus solved ,

Damit das Rastelement der Zugstange in die Ausnehmung des Riegels der Gegenkupplung eingreifen kann, ist die Zentrierkuppe auf der Vorderseite mit einer schlitzartigen Öffnung versehen, deren Höhe auf die Dicke des Riegels der Gegenkupplung abgestimmt ist und die ermöglicht, dass die Ausnehmung im Riegel der Gegenkupplung mit dem Rastelement der Zugstange in Eingriff gebracht werden kann.Thus, the locking element of the pull rod can engage in the recess of the bolt of the counter-coupling, the Zentrierkuppe is provided on the front with a slot-like opening whose height is matched to the thickness of the bolt of the counter-coupling and allows the recess in the bolt of the counter-coupling with the locking element of the pull rod can be brought into engagement.

Ein Nachteil eines derartigen Kupplungskopfs besteht darin, dass durch die Schweissverbindung zwischen der jeweiligen Zentrierkuppe und der Stirnplatte der Bereich des Fusspunkts der Zentrierkuppe korrosionsanfällig ist. Ein weiterer Nachteil besteht darin, dass durch die exponierte Lage der Zentrierkuppe diese dazu neigt, bei winterlichen Witterungsverhältnissen Schnee und Eis anzusetzen, was dazu führen kann, dass kein sicheres Kuppeln und Verriegeln der beiden Kupplungsköpfe mehr möglich ist. Obwohl Kupplungsköpfe mit elektrischen Heizungen bekannt sind, beispielsweise aus der EP-A-1 293 409 , besteht die Gefahr, dass die mechanisch beweglichen Teile sowie insbesondere auch der Bereich um die Zentrierkuppe herum Eis ansetzen. Dies rührt namentlich daher, dass nur die eigentliche Stirnplatte beheizt ist und durch das punktuelle Anschweissen der Zentrierkuppe an der Stirnplatte ein schlechter Wärmeübergang zwischen der Stirnplatte und der Zentrierkuppe besteht.A disadvantage of such a coupling head is that due to the welded connection between the respective centering tip and the end plate, the region of the base point of the centering tip is susceptible to corrosion. Another disadvantage is that due to the exposed position of the Zentrierkuppe this tends to start in winter weather conditions snow and ice, which can lead to the fact that no safe coupling and locking the two coupling heads is possible. Although coupling heads with electric heaters are known, for example from the EP-A-1 293 409 , There is a risk that the mechanically moving parts and especially the area around the Zentrierkuppe set ice around. This is due to the fact that only the actual face plate is heated and there is a poor heat transfer between the face plate and the Zentrierkuppe by the selective welding of Zentrierkuppe on the face plate.

Aus der EP-A-1 632 414 ist ein Kupplungskopf für Schienenfahrzeuge bekannt, der mit einer lösbaren Stirnplatte versehen ist. Die Befestigung der Stirnplatte am eigentlichen Kupplungskopfgehäuse erfolgt mittels Schrauben. Zwischen dem Kupplungskopfgehäuse und der Stirnplatte wird ein vorzugsweise aus Kunststoff bestehendes Ausgleichselement eingefügt. Die Stirnplatte ist auf der Rückseite mit Nuten versehen, in welchen Heizelemente aufgenommen sind.From the EP-A-1 632 414 is a coupling head for rail vehicles is known, which is provided with a releasable end plate. The attachment of the face plate on the actual coupling head housing by means of screws. Between the coupling head housing and the end plate, a preferably made of plastic compensation element is inserted. The front plate is provided on the back with grooves in which heating elements are added.

Die US 2 271 770 beschreibt eine automatische Kupplungsvorrichtung für Fahrzeuge, namentlich für Minen- oder Industriefahrzeuge. Die Kupplungsvorrichtung umfasst einen im wesentlichen hohlen Kopf, der auf der Vorderseite mit einer hohlen Nase versehen ist, welche die eine Hälfte der Stirnseite bildet. Die andere Hälfte der Stirnseite wird durch eine Öffnung gebildet, die der Aufnahme der Nase der Gegenkupplung dient. Die Nase ist zusammen mit dem den Kopf bildenden Gehäuse einstückig ausgebildet.The US 2 271 770 describes an automatic coupling device for vehicles, especially for mining or industrial vehicles. The coupling device comprises a essentially hollow head, which is provided on the front with a hollow nose, which forms one half of the front side. The other half of the front side is formed by an opening which serves to receive the nose of the counter-coupling. The nose is formed integrally with the housing forming the head.

Schliesslich ist aus der DE-C-662 874 eine selbsttätige Mittelpufferkupplung für Schienenfahrzeuge bekannt. Der Kupplungskopf ist mit einer Zentrierkuppe versehen, welche einstückig mit dem Kuppelgehäuse des Kupplungskopfs ausgebildet ist.Finally is from the DE-C-662 874 an automatic central buffer coupling for rail vehicles known. The coupling head is provided with a Zentrierkuppe, which is integrally formed with the dome housing of the coupling head.

Die Erfindung zielt darauf ab, einen Kupplungskopf für Schienenfahrzeuge derart weiterzubilden, dass er einfach und kostengünstig herstellbar ist, wobei sich das Gehäuse des Kupplungskopfs in besonders vorteilhafterweise zur Aufnahme von Heizelementen eignen soll, und wobei die Heizelemente derart angeordnet werden sollen, dass insbesondere auch die kritischen Bereiche des Kupplungskopfgehäuses, namentlich die Zentrierkuppe, beheizt werden können.The invention aims to develop a coupling head for rail vehicles such that it is simple and inexpensive to produce, with the housing of the coupling head is particularly suitable for receiving heating elements, and wherein the heating elements are to be arranged such that in particular the critical areas of the coupling head housing, namely the Zentrierkuppe, can be heated.

Hierzu wird nach der Erfindung ein Kupplungskopf gemäss dem Anspruch 1 bereitgestellt.For this purpose, according to the invention, a coupling head according to claim 1 is provided.

Indem zumindest die Stirnplatte zusammen mit der Zentrierkuppe einstückig ausgebildet ist und das Gehäuse mit mehreren Heizelementen versehen ist, wobei zumindest ein zumindest teilweise in die Zentrierkuppe führendes elektrisches Heizelement vorgesehen ist, kann sichergestellt werden, dass neben dem eigentlichen Gehäuse auch die exponierte Heizkuppe im Bedarfsfall zuverlässig beheizt und damit schnee- und eisfrei gehalten werden kann.By at least the end plate is formed integrally with the Zentrierkuppe and the housing is provided with a plurality of heating elements, wherein at least one at least partially leading into the Zentrierkuppe electric heating element is provided, it can be ensured that in addition to the actual housing and the exposed Heizkuppe if necessary reliable heated and thus snow and ice-free can be kept.

Die Figur 1 zeigt eine perspektivische Ansicht eines nach dem Stand der Technik ausgebildeten Gehäuses 2 eines Kupplungskopfs 1. Das Gehäuse 2 ist auf der Vorderseite mit einer Stirnplatte 3 versehen, deren Stirnfläche 4 die eigentliche Kupplungsfläche bildet. In diese Stirnplatte 3 sind zwei runde Öffnungen 5, 6 eingelassen. Die eine, im vorliegenden Beispiel in Blickrichtung gesehen linke Öffnung 5, dient der Aufnahme einer Zentrierkuppe 7 während die andere, in Blickrichtung gesehen rechte Öffnung 6 die Zentrieröffnung bildet. Die Zentrierkuppe 7 wird als separates Teil gegossen und ist viel dünnwandiger ausgebildet als das Gehäuse 2 oder die Stirnplatte 3. Die Zentrierkuppe 7 wird besonders während des Kupplungsvorgangs hohen Belastungen ausgesetzt. Durch die zweiteilige Ausführung können die Bauteile, entsprechend ihrer Funktion, aus unterschiedlichen Werkstoffen gefertigt werden. Die Stirnplatte 3 ist im Betrieb ebenfalls hohen Belastungen ausgesetzt. Im gekuppelten Betrieb reiben die Stirnplatten gegeneinander und müssen daher auch verschleissfest sein. Auf der Rückseite ist die Zentrierkuppe 7 mit einem zylindrischen Fortsatz 8 versehen, dessen Aussendurchmesser auf den Durchmesser der Öffnung 5 in der Stirnplatte abgestimmt ist. Die Zentrierkuppe ist auf der Rückseite zudem mit einem umlaufenden, als Anschlag dienen Bund 9 versehen. Zum Fixieren wird die Zentrierkuppe 7 in die Öffnung 5 eingeschoben und danach von der Rückseite der Stirnplatte 3 her angeschweisst. Dabei wird der zylindrische Fortsatz 8 der Zentrierkuppe 7 mittels mehrerer Schweisspunkte an der Zentrierplatte 3 befestigt.1 shows a perspective view of a formed according to the prior art housing 2 of a coupling head 1. The housing 2 is provided on the front with a face plate 3, the end face 4 forms the actual coupling surface. In this end plate 3, two round openings 5, 6 are embedded. The one, in the present example seen in the viewing direction left opening 5, serves to receive a Zentrierkuppe 7 while the other, seen in the viewing direction right opening 6 forms the centering. The Zentrierkuppe 7 is poured as a separate part and is much thinner walled than the housing 2 or the face plate 3. The Zentrierkuppe 7 is exposed to high loads especially during the coupling process. Due to the two-part design, the components, according to their function, can be made of different materials. The front plate 3 is also exposed during operation high loads. In coupled operation, the face plates rub against each other and therefore must also be wear-resistant. On the back of the Zentrierkuppe 7 is provided with a cylindrical extension 8, whose outer diameter is matched to the diameter of the opening 5 in the face plate. The Zentrierkuppe is also on the back with a circumferential, serving as a stop collar 9 provided. For fixing the Zentrierkuppe 7 is inserted into the opening 5 and then welded from the back of the face plate 3 ago. In this case, the cylindrical extension 8 of the Zentrierkuppe 7 is fastened by means of several welding points on the centering plate 3.

Die Fig. 2 zeigt in einer perspektivischen Ansicht ein bevorzugtes Ausführungsbeispiel eines Kupplungskopfgehäuses 11 für einen erfindungsgemäss ausgebildeten Kupplungskopf 10. Im vorliegenden Beispiel ist das gesamte Gehäuse 11 inklusive Stirnplatte 12 und Zentrierkuppe 13 einstückig ausgebildet. Die Stirnplatte 12 ist neben der Zentrierkuppe 13 wiederum mit einer Zentrieröffnung 14 versehen. Das Gehäuse 11 wird vorzugsweise aus einem Sphäroguss, insbesondere unter Verwendung einer Sandgussform hergestellt. Als Gusseisenwerkstoff hat sich insbesondere ADI (Austempered Ductile Iron) bewährt, bei dem der Kohlenstoff als Kugel ausgebildet ist und die Gefügematrix aus Ausferrit besteht. Der genannte Werkstoff ist auch unter dem Namen "bainitisches Gusseisen" bekannt. Nach dem Giessen wird das Gehäuse einer speziellen Wärmebehandlung unterzogen, bei der das Gehäusematerial seine spezifischen Eigenschaften, namentlich eine hohe Festigkeit, gute Dehnungseigenschaften sowie eine gute Verschleissbeständigkeit erhält. Damit ist es möglich, anstelle eines relativ teuren Vergütungsstahlgusses den kostengünstigeren ADI-Gusseisenwerkstoff für die Herstellung des Gehäuses zu verwenden. Das fertige Gehäuse weist gegenüber Stahl zudem ein vergleichsweise geringes Gewicht sowie sehr gute dynamische Eigenschaften auf.2 shows a perspective view of a preferred embodiment of a coupling head housing 11 for a coupling head 10 designed according to the invention. In the present example, the entire housing 11 including the end plate 12 and the centering tip 13 is integrally formed. The end plate 12 is in turn provided with a centering opening 14 next to the centering tip 13. The housing 11 is preferably made of a nodular cast iron, in particular using a sand mold. In particular, ADI (Austempered Ductile Iron), in which the carbon is in the form of a sphere and the matrix consists of ausferrite, has proven successful as a cast iron material. The named material is also known as "bainitic cast iron". After casting, the housing is subjected to a special heat treatment in which the housing material obtains its specific properties, namely high strength, good elongation properties and good wear resistance. This makes it possible, instead of a relatively expensive tempered steel casting to use the lower-cost ADI cast iron material for the production of the housing. The finished housing also has a comparatively low weight compared to steel and very good dynamic properties.

Fig. 3 zeigt eine perspektivische Ansicht des mit einem Gehäuse 11 gemäss Fig. 2 versehenen Kupplungskopfs 10, wobei das Gehäuse 11 nur durch dünne Linien angedeutet ist und insbesondere der durch mechanische Kupplungs- und Zentrierelemente gebildete Verriegelungsmechanismus des Kupplungskopfs 10 ersichtlich ist. An der Unterseite der Stirnplatte 12 ist ein nach vorne abstehender, abgewinkelter Leitarm 15 befestigt, der beim Kupplungsvorgang dem Vorzentrieren der beiden miteinander zu verbindenden Kupplungsköpfe dient. Im Innern des Kupplungskopf-Gehäuses 11 ist ein Riegel 16 angeordnet, der an einer vertikal verlaufenden Welle 17 drehbar abgestützt ist. Dieser Riegel 16 ist zwischen einer Ausgangs- und einer Wirkstellung verdrehbar. Auf der einen Seite des Riegels 16 ist eine Zugstange 18 drehbar an dem Riegel 16 abgestützt. Diese Zugstange 18 ist bügelartig ausgebildet und endseitig mit einem Rastelement 19 versehen. Auf der der Zugstange 18 gegenüberliegenden Seite ist der Riegel 16 mit einer Ausnehmung 20 versehen, an der die Zugstange der Gegenkupplung mit ihrem Rastelement formschlüssig angreifen kann. Damit das Rastelement 19 der Zugstange 18 in die Ausnehmung des Riegels der Gegenkupplung eingreifen kann, ist die Zentrierkuppe 13 auf der Vorderseite mit einer schlitzartigen Öffnung 21 versehen, deren Höhe auf die Dicke des Riegels der Gegenkupplung abgestimmt ist und die ermöglicht, dass die Ausnehmung im Riegel der Gegenkupplung mit dem Rastelement 19 der Zugstange 18 in Eingriff gebracht werden kann. Ein mit einem Handgriff 23 versehener Entriegelungshebel 22 dient dem manuellen Entkuppeln des Kupplungskopfs.FIG. 3 shows a perspective view of the coupling head 10 provided with a housing 11 according to FIG. 2, wherein the housing 11 is indicated only by thin lines and in particular the locking mechanism of the coupling head 10 formed by mechanical coupling and centering elements can be seen. At the bottom of the end plate 12, a forward projecting, angled Leitarm 15 is attached, which serves in the coupling process precentering the two coupling heads to be joined together. In the interior of the coupling head housing 11, a latch 16 is arranged, which is rotatably supported on a vertically extending shaft 17. This latch 16 is rotatable between an initial and an operative position. On the one side of the bolt 16, a pull rod 18 is rotatably supported on the latch 16. This pull rod 18 is bow-shaped and end provided with a locking element 19. On the opposite side of the pull rod 18, the bolt 16 is provided with a recess 20 to which the pull rod of the mating coupling can engage positively with its locking element. Thus, the locking element 19 of the pull rod 18 can engage in the recess of the bolt of the counter-coupling, the Zentrierkuppe 13 is provided on the front with a slot-like opening 21 whose height is matched to the thickness of the bolt of the counter-coupling and allows the recess in the Latch the counter-coupling with the locking element 19 of the pull rod 18 can be brought into engagement. A provided with a handle 23 release lever 22 is used for manual uncoupling of the coupling head.

Fig. 4 zeigt das mit Heizelementen versehene Gehäuse gemäss Fig. 2 in einer Ansicht von vorne. Das Gehäuse 11 ist mit insgesamt sieben Heizelementen 25, 26, 27, 28, 29, 30, 31 in Form von elektrischen Heizstäben versehen. Von diesen sieben Heizelementen 25, 26, 27, 28, 29, 30, 31 sind vier Heizelemente 25, 26, 27, 28 auf der Rückseite der Stirnplatte 12 angeordnet. Die Längsachsen dieser vier Heizelemente 25, 26, 27, 28 verlaufen dabei horizontal. Zwei weitere Heizelemente 29, 30 sind im rückwärtigen Bereich des Gehäuses 11 angeordnet, wobei deren Längsachsen vertikal verlaufen. Ein weiteres Heizelement 31 schliesslich ist im Bereich der Zentrierkuppe 13 angeordnet. Durch die Anordnung der sieben Heizelemente soll sichergestellt werden, dass der gesamte Kupplungskopf derart beheizt werden kann, dass auch unter widrigsten Bedingungen wie beispielsweise gefrierendem Regen oder starkem Schneefall ein sicheres Kuppeln und Entkuppeln möglich ist. Durch die gezeigte Anordnung der Heizelemente wird das Gehäuse bei vergleichsweise kleiner Leistungsaufnahme rundum beheizt. Namentlich wird die ganze Oberfläche des Gehäuses aussen und innen beheizt. Dadurch ist kein zusätzlicher Schutz wie z.B. eine Abdeckung, eine Kunststoffhülle um den Kupplungskopf o.ä. im Winterbetrieb notwendig.Fig. 4 shows the housing provided with heating elements according to FIG. 2 in a front view. The housing 11 is provided with a total of seven heating elements 25, 26, 27, 28, 29, 30, 31 in the form of electric heating rods. Of these seven heating elements 25, 26, 27, 28, 29, 30, 31 four heating elements 25, 26, 27, 28 are arranged on the back of the end plate 12. The longitudinal axes of these four heating elements 25, 26, 27, 28 extend horizontally. Two further heating elements 29, 30 are arranged in the rear region of the housing 11, wherein the longitudinal axes extend vertically. Finally, a further heating element 31 is arranged in the region of the centering tip 13. The arrangement of the seven heating elements to ensure that the entire coupling head can be heated so that even under the most adverse conditions such as freezing rain or heavy snowfall safe coupling and decoupling is possible. The arrangement of the heating elements shown, the housing is heated at a comparatively low power consumption. In particular, the entire surface of the housing is heated outside and inside. Thereby no additional protection such as a cover, a plastic cover around the coupling head or similar necessary in winter operation.

Die Fig. 5 zeigt das mit Heizelementen versehene Gehäuse gemäss Fig. 2 in einer Ansicht von der Seite. Aus dieser Darstellung ist insbesondere die Lage von zwei der vier auf der Rückseite der Stirnplatte 12 angeordneten Heizelemente 25, 28 ersichtlich. Zudem ist eines der beiden im rückwärtigen Bereich des Gehäuses 11 angeordneten Heizelemente 29 sowie das schräg in die Zentrierkuppe 13 führende Heizelement 31 ersichtlich.Fig. 5 shows the housing provided with heating elements according to FIG. 2 in a view from the side. From this representation, in particular the position of two of the four arranged on the back of the face plate 12 heating elements 25, 28 can be seen. In addition, one of the two is arranged in the rear region of the housing 11 Heating elements 29 and the obliquely leading into the Zentrierkuppe 13 heating element 31 can be seen.

Die Fig. 6 zeigt das mit Heizelementen versehene Gehäuse gemäss Fig. 2 in einer Ansicht von oben. Aus dieser Darstellung ist insbesondere die Lage der beiden im rückwärtigen Bereich des Gehäuses 11 angeordnete Heizelemente 29, 30 ersichtlich. Zudem sind zwei der vier auf der Rückseite der Stirnplatte 12 angeordneten Heizelemente 25, 26 sowie wiederum das schräg in die Zentrierkuppe 13 führende Heizelement 31 gut erkennbar. Das Heizelement 31 ist durch die Stirnplatte 12 hindurch in die Zentrierkuppe 13 geführt.Fig. 6 shows the housing provided with heating elements according to FIG. 2 in a view from above. From this representation, in particular the position of the two arranged in the rear region of the housing 11 heating elements 29, 30 can be seen. In addition, two of the four arranged on the back of the face plate 12 heating elements 25, 26 and in turn the obliquely leading into the Zentrierkuppe 13 heating element 31 are clearly visible. The heating element 31 is guided through the end plate 12 into the Zentrierkuppe 13.

Fig. 7 schliesslich zeigt einen Längsschnitt durch das Gehäuse 11 des Kupplungskopfs gemäss Fig. 3. Aus dieser Darstellung ist insbesondere das schräg in die Zentrierkuppe 13 führende Heizelement 31 erkennbar. Dieses Heizelement 31 ist durch die Stirnplatte 12 hindurch bis in die Wandung 13a der Zentrierkuppe 13 geführt und dient dem Beheizen der gesamten Zentrierkuppe 13. Damit soll einerseits die für die Zentrierung wichtige Mantelfläche auf der Aussenseite der Zentrierkuppe 13 von Eis und Schnee freigehalten werden. Zudem soll verhindert werden, dass sich die Öffnung 21 mit Schnee und/oder Eis zusetzen kann, was ein korrektes Verriegeln der miteinander zu verbindenden Kupplungsköpfe verunmöglichen würde. Insbesondere auch die einstückige Gestaltung des Gehäuses 11 mitsamt der Stirnplatte 12 und der Zentrierkuppe 13 sowie die Anordnung des schräg in die Zentrierkuppe 13 führenden Heizelements 31 begünstigt ein zuverlässiges Freihalten der Zentrierkuppe von Eis und Schnee. Die Wandstärke der Zentrierkuppe 13 ist zumindest in dem Bereich, in dem das Heizelement 31 aufgenommen werden soll, so gewählt, dass das Heizelement 31 vom Material der Zentrierkuppe 13 vollständig umschlossen ist.Finally, FIG. 7 shows a longitudinal section through the housing 11 of the coupling head according to FIG. 3. From this representation, in particular the heating element 31 which leads obliquely into the centering point 13 can be seen. This heating element 31 is guided through the end plate 12 into the wall 13a of the Zentrierkuppe 13 and serves to heat the entire Zentrierkuppe 13. Thus, on the one hand important for the centering lateral surface on the outside of the Zentrierkuppe 13 of ice and snow are kept free. In addition, it should be prevented that the opening 21 can be clogged with snow and / or ice, which would make impossible a correct locking of the coupling heads to be joined together. In particular, the one-piece design of the housing 11 together with the end plate 12 and the Zentrierkuppe 13 and the arrangement of obliquely leading into the Zentrierkuppe 13 heating element 31 favors a reliable keeping clear of the centering of ice and snow. The wall thickness of the Zentrierkuppe 13 is at least in the area in which the heating element 31 is to be received, selected so that the heating element 31 is completely surrounded by the material of the Zentrierkuppe 13.

Das jeweilige Heizelement 25, 26, 27, 28, 29, 30, 31 ist zylindrisch ausgebildet und auf der Rückseite mit einem Sechskant-Kopf versehen, an dem ein Schraubenschlüssel angesetzt werden kann. Vor dem Sechskant-Kopf ist ein Gewinde angeordnet, welches der Befestigung des jeweiligen Heizelements in einer dafür vorgesehenen GewindeBohrung im Gehäuse 11 des Kupplungskopfs 10 dient. Der Durchmesser der jeweiligen, zur Aufnahme eines Heizelements im Gehäuse vorgesehenen Bohrung ist unwesentlich grösser als der zylindrische Abschnitt des Heizelements, so dass ein guter Wärmeübergang vom Heizelement auf das Gehäuse gewährleistet ist. Jedenfalls wird das Heizelement vom Gehäuse bzw. der jeweiligen Gehäusewandung immer vollumfänglich umschlossen.The respective heating element 25, 26, 27, 28, 29, 30, 31 is cylindrical and provided on the back with a hexagonal head to which a wrench can be attached. A thread is arranged in front of the hexagonal head, which serves to fasten the respective heating element in a threaded bore provided in the housing 11 of the coupling head 10. The diameter of the respective, provided for receiving a heating element in the housing bore is insignificantly larger than the cylindrical portion of the heating element, so that a good Heat transfer from the heating element is ensured on the housing. In any case, the heating element is always fully enclosed by the housing or the respective housing wall.

Durch die gezeigte Anordnung der insgesamt sieben Heizelemente wird sichergestellt, dass die Kupplung auch unter widrigen Wetter-Bedingungen einwandfrei funktioniert, indem sämtliche für den Kupplungsvorgang relevanten Bereiche und Teile des Kupplungskopfs durch die Heizelemente soweit erwärmt werden können, dass weder Eis noch Schnee in nennenswerter Menge daran haften bleiben. In diesem Zusammenhang soll spezifisch auf die beheizbare Zentrierkuppe 13 hingewiesen werden, welche durch die einstückige Ausbildung zusammen mit der Stirnplatte 12 nicht nur bezüglich der Beheizbarkeit wesentliche Vorteile gegenüber einer an der Stirnplatte angeschweissten Zentrierkuppe aufweist. Die einstückige Ausbildung der Zentrierkuppe 13 zusammen mit der Stirnplatte 12 hat zusätzlich den Vorteil, dass keine Gefügeänderungen im Bereich der Schweissnaht vorhanden sind, die sich im Betrieb unter ungünstiger Belastung und/oder im Dauereinsatz negativ auswirken könnten. Da das Schweissen entfällt, können sich die genannten Teile auch nicht durch den Schweissvorgang verziehen. Schliesslich ist durch die einstückige Gestaltung insbesondere auch die Korrosionsanfälligkeit im Bereich der sonst nötigen Schnittstelle der beiden Bauteile eliminiert, zumal es bei den bis anhin eingesetzten, mittels Schweissen befestigten Zentrierkuppen im Bereich der Schweissnaht immer wieder zu Korrosion kommt. Diesbezüglich ist es wesentlich einfacher, einen einstückig ausgebildeten Kupplungskopf durch eine entsprechende Beschichtung, beispielsweise eine katalytische Tauchlackierung, zu schützen und anschliessend zu lackieren.The arrangement shown, the total of seven heating elements ensures that the clutch works well even under adverse weather conditions by all relevant for the coupling process areas and parts of the coupling head can be heated by the heating elements so far that neither ice nor snow in any significant amount stick to it. In this context, reference should be made specifically to the heatable Zentrierkuppe 13, which has not only in terms of heatability essential advantages over a welded on the end plate Zentrierkuppe by the integral formation together with the end plate 12. The one-piece design of the Zentrierkuppe 13 together with the face plate 12 has the additional advantage that no structural changes in the area of the weld are present, which could have a negative impact during operation under unfavorable load and / or in continuous use. Since the welding is omitted, the parts mentioned can not forgive themselves by the welding process. Finally, the one-piece design also eliminates in particular the susceptibility to corrosion in the area of the otherwise necessary interface of the two components, especially as corrosion occurs repeatedly in the centering studs which have been attached by means of welding in the region of the weld seam. In this regard, it is much easier to protect an integrally formed coupling head by an appropriate coating, such as a catalytic dip coating, and then to paint.

Anstelle eines gesamthaft einstückig ausgebildeten Gehäuses könnte dieses natürlich auch zwei- oder mehrteilig ausgebildet werden. In jedem Fall ist jedoch zumindest die Stirnplatte zusammen mit der Zentrierkuppe einstückig ausgebildet. Durch die Einstückigkeit können die Herstellkosten, namentlich durch das Wegfallen von Füge- und/oder Montagearbeiten, reduziert werden.Instead of a total integrally formed housing this could of course be formed in two or more parts. In any case, however, at least the end plate is integrally formed together with the Zentrierkuppe. Due to the integral nature of the manufacturing costs, especially by eliminating joining and / or assembly work can be reduced.
