Technisches Gebiet Technical area
Die Erfindung betrifft eine Schienenfahrzeugkupplung für die Kopplung eines Schienenfahrzeugs mit einem Schienenfahrzeug in Sänftenbauweise. The invention relates to a rail vehicle coupling for the coupling of a rail vehicle with a rail vehicle in sedan construction.
Stand der Technik State of the art
Typische Passagierschienenfahrzeuge weisen zwei Drehgestelle auf und können mit weiteren Fahrzeugen gekuppelt werden. Typical passenger rail vehicles have two bogies and can be coupled with other vehicles.
Spezielle Zugkonfigurationen erfordern jedoch keine However, special train configurations do not require one
betriebsmäßige Trennbarkeit der Fahrzeugzusammenstellung, sodass andere Fahrzeugkonzepte eingesetzt werden können. Dies betrifft insbesondere U-Bahnen und Straßenbahnen, bei welchen beispielsweise auch sogenannte Sänftenwagen eingesetzt werden, welche kein eigenes Drehgestell umfassen sondern von den benachbarten Fahrzeugen getragen werden. Solcherart kann eine Einsparung an teuren Drehgestellen realisiert werden, wenn die erlaubte Achslast der Strecke die Erhöhung der Last an den verbleibenden Drehgestellen ermöglicht. Zwischen einem konventionellen und einem Sänftenwagen ist eine spezifische Kupplung vorgesehen, welche die Betriebs- und Gewichtskräfte übermittelt und welche die erforderliche Beweglichkeit für Kurven- Kuppen- und Wannenfahrten sicherstellt. Dafür sind insbesondere Kugelgelenke gut geeignet. Jedoch sind Maßnahmen zu treffen um ein Kippen des Sänftenwagens zu verhindern. Dazu werden die gekuppelten Fahrzeuge mittels eines Lenkers verbunden, wobei der Lenker an jedem Fahrzeug gelenkig angebunden ist und ein Kippen der Fahrzeuge zueinander verhindert, d.h. einen Bewegungsfreiheitsgrad des Operational separability of the vehicle composition, so that other vehicle concepts can be used. This concerns in particular subways and trams, in which, for example, so-called litter cars are used, which do not include their own bogie but are carried by the adjacent vehicles. Such a saving of expensive bogies can be realized if the allowable axle load of the track allows the load on the remaining bogies to be increased. Between a conventional and a litter car, a specific clutch is provided, which transmits the operating and weight forces and which ensures the required mobility for curves Kuppen- and tub runs. In particular, ball joints are well suited. However, measures must be taken to prevent tilting of the pickup truck. These are the coupled vehicles by means of a handlebar connected, wherein the handlebar is hinged to each vehicle and prevents tilting of the vehicles to each other, ie, a degree of freedom of movement

Lenker zu übermittelnden Kräfte aufgrund der Hebelgesetze im Vergleich zu einer Anordnung im Untergestellbereich reduziert sind. Bei kleinen Fahrzeugen mit untypisch geringem Handlebars to be transmitted forces are reduced due to the leverage laws compared to an arrangement in the underframe area. For small vehicles with untypical low
Querschnitt ist eine solche Anordnung jedoch nicht möglich, sodass das Sänftenprinzip gegebenenfalls nicht anwendbar ist. Cross-section, however, such an arrangement is not possible, so the litter principle may not be applicable.

Dadurch ist der Vorteil erzielbar, eine Wankbewegung der beiden miteinander gekuppelten Schienenfahrzeuge zueinander verhindern zu können, wobei der entsprechende Freiheitsgrad der Kupplung um die Längsachse gesperrt ist. Es ist As a result, the advantage is achievable to prevent a rolling motion of the two interconnected rail vehicles to each other, the corresponding degree of freedom of the clutch is locked to the longitudinal axis. It is
wesentlich, dass die beiden weiteren Freiheitsgrade um die Hochachse und um die Querachse der Kupplung dabei essential that the two other degrees of freedom around the vertical axis and about the transverse axis of the clutch
unbeeinflußt und frei bleiben, sodass die Kupplung bei unaffected and remain free, so that the clutch at
Kurven- Kuppen- und Wannenfahrten die entsprechenden Curves - dome and tub trips the corresponding
Verschwenkungen der Fahrzeuge zueinander ermöglicht. Alleine der Freiheitsgrad der Kupplung um die Längsachse, also auch um die Längsachse der gekuppelten Fahrzeuge ist beeinflußt. Somit kann ein wanksteifes Gelenk ohne Lenker im Dachbereich geschaffen werden. Swiveling the vehicles allows each other. Alone the degree of freedom of the coupling about the longitudinal axis, that is also about the longitudinal axis of the coupled vehicles is affected. Thus, a stagger-resistant joint can be created without handlebars in the roof area.
Erfindungsgemäß umfasst die Schienenfahrzeugkupplung ein Gelenkauge und eine Gelenkgabel, welche jeweils zur lösbaren Befestigung mit je einem Wagenkasten ausgebildet sind. Für diese Befestigung können Schraubverbindungen eingesetzt werden. Ein sphärisches Gelenk (Kugelgelenk) bildet die Verbindungsstelle zwischen der Gelenkgabel und dem Gelenkauge und ist mit dem Gelenkauge verbunden, sodass diese beiden Bauteile (Gelenkgabel und Gelenkauge) zueinander drei According to the invention the rail vehicle coupling comprises a joint eye and a yoke, which are each designed for releasable attachment, each with a car body. For this attachment screw can be used. A spherical joint (ball joint) forms the joint between the joint fork and the joint eye and is connected to the joint eye, so that these two components (joint fork and joint eye) to each other three

Längsachse durch weitere Maßnahmen gesperrt ist. Dazu ist die Gelenkgabel mit einer Achse ausgestattet, welche mit ihr verbunden ist und welche das sphärische Gelenk durchdringt und somit die Verbindung zu dem Gelenkauge herstellt. Diese Achse ist an beiden Enden verlängert und so ausgeführt, dass sie in eine Ausnehmung (Gleitführung) des Gelenkauges eingreifen kann und in dieser Gleitführung beweglich ist. Diese Gleitführung ist in Einbaulage der Schienenfahrzeugkupplung waagrecht angeordnet. Dadurch ist der Freiheitsgrad um die Hochachse (Kurvenfahrt) frei, da bei Kurvenfahrt die Enden der Achse entlang der Form der Longitudinal axis is blocked by further measures. For this purpose, the yoke is equipped with an axle which is connected to it and which penetrates the spherical joint and thus establishes the connection to the joint eye. This axis is extended at both ends and designed so that it can engage in a recess (sliding guide) of the joint eye and is movable in this sliding guide. This slide is arranged horizontally in the installed position of the rail vehicle coupling. As a result, the degree of freedom about the vertical axis (cornering) is free, since when cornering, the ends of the axis along the shape of the

Eine bevorzugte Ausführungsform der Erfindung sieht vor, die in der Gleitführung geführten Abschnitte der Achse mit je einem Gleitkörper auszustatten, welche diese Abschnitte umfasst. Diese Gleitkörper bilden dabei eine die Enden der Achse umgebende Hülse, sodass die Achse selbst nicht in unmittelbaren Kontakt mit der Gleitführung gerät. Dadurch ist der Vorteil erzielbar, ein besseres Gleit- und A preferred embodiment of the invention provides to equip the guided in the sliding guide portions of the axis with a respective sliding body comprising these sections. These sliding bodies form a sleeve surrounding the ends of the axle, so that the axle itself does not come into direct contact with the sliding guide. As a result, the advantage can be achieved, a better sliding and

Eine weitere bevorzugte Ausführungsform der Erfindung sieht vor, die Gleitkörper elastisch auszuführen. Dabei werden die Gleitkörper mit einer bestimmten Nachgiebigkeit ausgeführt, beispielsweise durch eine entsprechende Materialwahl oder Formgebung, sodass die Wanksteifigkeit des Gelenks (der Kupplung) reduziert ist. Solcherart werden geringe Verdrehungen um die Längsachse zugelassen, was die A further preferred embodiment of the invention provides to perform the sliding body elastic.

Eine weitere bevorzugte Ausführungsform der Erfindung sieht vor, die Gleitkörper gegenüber der Achse drehbar auszuführen. Dabei werden die Gleitkörper mit einer zylindrischen Bohrung ausgestattet, durch welche die Enden der Achse geführt sind. Die äußere Form der Gleitkörper kann dabei auch ebene Flächen aufweisen um einen flächigen Kontakt mit der Gleitführung herzustellen. Solcherart kann ein deutlich geringerer A further preferred embodiment of the invention provides to make the sliding body rotatable relative to the axis. The sliding bodies are equipped with a cylindrical bore through which the ends of the axle are guided.
