Description
Die Erfindung betrifft eine Gelenkkupplung, welche zur semipermanenten Verbindung zweier Fahrzeugeinheiten eines Schienenfahrzeuges geeignet ist. Eine solche Gelenkkupplung ist beispielsweise aus der
Die
Stützen sich zwei Wagenkastenenden eines Schienenfahrzeugs auf einem gemeinsamen Drehgestell ab, so spricht man von einem Jakobs-Drehgestell. Die einzelnen Fahrzeugeinheiten des Schienenfahrzeugs sind in diesem Fall durch eine so genannte Kurzkupplung verbunden, welche in der Regel nur zu Wartungs- oder Reparaturzwecken gelöst wird. Kurzkupplungen können zur semipermanenten Verbindung von zwei oder mehr Fahrzeugen verwendet werden und sind beispielsweise in S-Bahnzügen zu finden. Ebenso finden Kurzkupplungen im Güterverkehr Verwendung. In jedem Fall ist eine Beweglichkeit der Gelenkkupplung in allen drei Raumrichtungen erforderlich.Supporting two car body ends of a rail vehicle on a common bogie, so it is called a Jakobs bogie. The individual vehicle units of the rail vehicle are connected in this case by a so-called close coupling, which is usually solved only for maintenance or repair purposes. Short couplings can be used for semi-permanent connection of two or more vehicles and can be found, for example, in S-Bahn trains. Likewise, short couplings are used in freight transport. In any case, a mobility of the universal joint in all three spatial directions is required.
Der Erfindung liegt die Aufgabe zugrunde, eine für Schienenfahrzeuge geeignete Gelenkkupplung anzugeben, welche sich bei beanspruchungsgerechter Konstruktion durch eine besonders leichte Montierbarkeit auszeichnet.The invention has for its object to provide a suitable for rail vehicles articulated coupling, which is characterized by a particularly easy mounting in stress-resistant design.
Diese Aufgabe wird erfindungsgemäß gelöst durch eine Gelenkkupplung mit den Merkmalen des Patentanspruchs 1. Die Gelenkkupplung weist einen auch als Mutterstück bezeichneten Gabelkopf mit zwei Gabelstücken auf, sowie eine auch als Vaterstück bezeichnete Kupplungslasche. Im mit einer ersten Fahrzeugeinheit verbundenen Gabelkopf ist ein Bolzen gehalten, welcher ein sphärisches Gelenk durchsetzt, das in der Kupplungslasche aufgenommen ist, die mit einer zweiten Fahrzeugeinheit verbunden ist. Zur Fixierung des vorzugsweise in horizontaler Einbaulage angeordneten Bolzens im Gabelstück ist ein Keil vorgesehen, der in axialer Richtung des Bolzens angeordnet ist und eine konkav gekrümmte, der zylindrischen Krümmung der Oberfläche des Bolzens angepasste Oberfläche aufweist. Die Erstreckungsrichtung, d.h. die Vorschubrichtung, des Keils stimmt somit mit der Axialrichtung des Bolzens überein. Die als Kurzkupplung ausgebildete Gelenkkupplung zeichnet sich durch einen einfachen Aufbau und eine hohe Steifigkeit bei zugleich geringem Gewicht aus.This object is achieved by a joint coupling with the features of
Vorzugsweise ist der Keilwinkel derart bemessen, dass der Keil selbsthemmend zwischen dem Bolzen und einer Anlagefläche des Gabelstücks gehalten wird. Weiter kann der den Bolzen spielfrei im Gabelkopf fixierende Keil mittels Verschraubungen am Gabelstück und / oder am Bolzen befestigt sein. Während der Keil eine konkav gekrümmte und eine dieser gegenüberliegende, vorzugsweise abgeflachte Seite aufweist, ist der Bolzen entweder vollständig zylindrisch geformt oder überwiegend zylindrisch mit einer achsparallelen Abflachung. In jedem Fall liegt der Keil an einem zylindrisch gekrümmten Abschnitt des Bolzens an. Die vom Bolzen abgewandte, am Gabelkopf anliegende Oberfläche des Keils kann konvex gekrümmt sein, so dass beide für die Keilwirkung verantwortlichen Oberflächen des Keils eine Krümmung aufweisen. Damit sind durch den Keil Kräfte erzeugbar, die besonders gleichmäßig radial von außen auf den Bolzen einwirken.Preferably, the wedge angle is dimensioned such that the wedge is held in a self-locking manner between the bolt and a contact surface of the fork piece. Next, the bolt without play in the clevis fixing wedge by means of screws on the fork piece and / or be attached to the bolt. While the wedge has a concavely curved and one of these opposite, preferably flattened side, the bolt is either completely cylindrical shaped or predominantly cylindrical with an axis-parallel flattening. In any case, the wedge abuts a cylindrically curved portion of the bolt. The wedge-facing surface of the wedge facing away from the bolt may be convexly curved so that both wedge-engaging surfaces of the wedge have a curvature. This forces can be generated by the wedge, which act particularly even radially from the outside on the bolt.
Die Abflachung des Bolzens liegt ggf. an einer Anlagefläche des Gabelstücks an, welche normal zur Längsrichtung des Gabelstücks, d.h. normal zur mit der Fahrzeugslängsrichtung übereinstimmenden Zugrichtung, angeordnet ist. Die am Gabelstück gebildete Anlagefläche erstreckt sich unabhängig davon, ob der Bolzen abgeflacht ist, bevorzugt beiderseits einer Ebene, welche durch die Achse des Bolzens verläuft und deren Normale mit der Fahrzeugslängsrichtung einen rechten Winkel einschließt. Bei horizontaler Einbaulage des Bolzens handelt es sich hierbei um eine horizontale Ebene. Auf der einen Seite dieser Ebene erstreckt sich die Anlagefläche des Gabelstücks vorzugsweise über einen Winkel von weniger als 90°, bezogen auf den Umfang des Bolzens, während auf der anderen Seite der Ebene die Anlagefläche einen Winkel von mehr als 90° überstreicht. Insgesamt liegt der Bolzen vorzugsweise mit etwas weniger als der Hälfte seines Umfangs am Gabelstück an. Dies ermöglicht eine besonders einfache Montage des Bolzens. Die Gabelstücke weisen entsprechende Öffnungen auf, die ein Einsetzen des Bolzens im Wesentlichen in radialer Richtung ermöglichen. Im montierten Zustand der Gelenkkupplung liegt der Keil in bevorzugter Ausgestaltung an mindestens 1/6 des Umfangs des Bolzens an. Mindestens 2/3 des Umfangs des Bolzens kontaktieren in dieser Ausgestaltung entweder das Gabelstück oder den Keil. Zur einfachen Demontage des Keils kann in diesen eine Abziehvorrichtung, insbesondere ein Abziehgewinde, integriert sein.The flattening of the bolt may be applied to a contact surface of the fork which is normal to the longitudinal direction of the fork, i. is arranged normal to the direction of travel coinciding with the vehicle longitudinal direction of pull. The contact surface formed on the fork extends, regardless of whether the bolt is flattened, preferably on both sides of a plane which passes through the axis of the bolt and whose normal encloses a right angle with the vehicle longitudinal direction. In the horizontal installation position of the bolt, this is a horizontal plane. On one side of this plane, the contact surface of the fork piece preferably extends over an angle of less than 90 °, relative to the circumference of the bolt, while on the other side of the plane, the contact surface extends over an angle of more than 90 °. Overall, the bolt is preferably at a little less than half of its circumference on the fork. This allows a particularly simple installation of the bolt. The fork pieces have corresponding openings, which allow insertion of the bolt substantially in the radial direction. In the assembled state of the universal joint of the wedge is in a preferred embodiment of at least 1/6 of the circumference of the bolt. At least 2/3 of the circumference of the bolt in this embodiment contact either the fork piece or the wedge. For easy disassembly of the wedge may be in these a puller, in particular a peel-off, integrated.
Das sphärische Gelenk, welches eine Winkelbeweglichkeit um alle drei Raumachsen ohne lineare Freiheitsgrade aufweist, kann für eine Fett- oder Ölschmierung vorgesehen und / oder mit einem Gleitgewebe ausgeführt sein. In jedem Fall kann der Außenring des Gelenks einteilig oder mehrteilig, insbesondere in Form eines gesprengten Lagerrings, gefertigt sein. Der Innenring des sphärischen Gelenks, welcher vom Bolzen durchdrungen ist, ist vorzugsweise ein vom Bolzen getrenntes Teil. Alternativ ist der Innenring mit dem Bolzen einteilig ausgebildet.The spherical joint, which has an angular mobility around all three spatial axes without linear degrees of freedom, can be provided for a grease or oil lubrication and / or be designed with a sliding fabric. In each Case, the outer ring of the joint can be made in one piece or in several parts, in particular in the form of a blasted bearing ring. The inner ring of the spherical joint, which is penetrated by the bolt, is preferably a separate part from the bolt. Alternatively, the inner ring is integrally formed with the bolt.
Ein effektiver Schutz des sphärischen Gelenks vor Verschmutzung oder anderen den Verschleiß fördernden Einflüssen wie Feuchtigkeit, Eis, Schnee, Staub oder eventuell verunreinigten Schmierstoffen ist mittels einer vorzugsweise als Faltenbalgdichtung ausgeführten Abdichtung erreichbar. Ebenso ist ein in der Anmeldung
Die Abdichtung ist ohne Einschränkung der Beweglichkeit des sphärischen Gelenks derart montiert, dass am Gelenk gehaltene Bereiche der Abdichtung bei Bedarf, beispielsweise bei einem Drehgelenkwechsel, durchrutschen können, ohne eine Beschädigung der Abdichtung zu riskieren. Zur zuverlässigen Fixierung der Abdichtung sind Spannelemente wie Runddrahtringe oder Wurmfedern geeignet, wobei eine Vorspannung des eigentlichen Faltenbalgmaterials nicht erforderlich ist. Die Spannelemente umgreifen beispielsweise zu beiden Seiten des sphärischen Gelenks den Bolzen umgebende Stützringe, welche Axialkräfte, die auf das sphärische Gelenk wirken, aufnehmen. Jeder Stützring ist dabei zwischen dem Innenring des sphärischen Gelenks und einem der Gabelstücke angeordnet. Nach einer alternativen Ausgestaltung sind die beiden Stützringe integrale Bestandteile des Innenrings.The seal is mounted without limiting the mobility of the spherical joint such that portions of the seal retained on the joint may slip when needed, such as a pivot joint, without risking damage to the seal. For reliable fixation of the seal clamping elements such as round wire rings or worm springs are suitable, with a bias of the actual bellows material is not required. The clamping elements encompass, for example on both sides of the spherical joint surrounding the bolt support rings, which absorb axial forces acting on the spherical joint. Each support ring is arranged between the inner ring of the spherical joint and one of the fork pieces. According to an alternative embodiment, the two support rings are integral components of the inner ring.
In allen Ausführungsformen weist die Gelenkkupplung eine günstige Pressungsverteilung sowie im Zusammenhang damit ein hohes Kraftaüfnahmevermögen auf, wobei eine Trennung oder Verbindung der Kupplung ebenso wie ein Austausch einzelner Lagerelemente mit geringem Aufwand möglich ist.In all embodiments, the joint coupling has a favorable pressure distribution and, in connection therewith, a high capacity for absorbing forces, wherein a separation or connection of the coupling as well as an exchange of individual bearing elements is possible with little effort.
