Description
Die Erfindung betrifft einen Güterwaggen mit einer Schiebewand, wie er im Oberbegriff des Anspruchs 1 beschrieben ist.The invention relates to a freight car with a sliding wall, as he in the preamble of claim 1 is described.
Bei Güterwaggons besteht das Bedürfnis nach einer exakten, vollständigen Führung der Schiebewand aus ihrer Schließstellung bzw. in ihre Schließstellung, die überdies möglichst reibungsarm erfolgen soll.With freight wagons, there is a need for an exact, complete guidance of the Sliding wall from its closed position or in its closed position, moreover, if possible should take place with little friction.
Aus der AT 246 773 B ist eine untere Ausstellvorrichtung für eine Schiebewand bekannt, welche Parallelogrammgestänge aufweist, die aus jeweils zwei im wesentlichen parallelen Schwenkhebeln und einer diese Hebel verbindenden Brücke bestehen. Einer der Schwenkhebel eines Parallelogrammgestänges ist mit einer den Parallelogrammgestängen gemeinsamen Welle verbunden, und durch ein Verdrehen der Welle kann das Parallelogrammgestänge aus einer angehobenen in eine abgesenkte Position verschwenkt werden.From AT 246 773 B a lower opening device for a sliding wall is known, which Has parallelogram linkage, each consisting of two substantially parallel pivot levers and a bridge connecting these levers. One of the swivel levers Parallelogram linkage is with a shaft common to the parallelogram linkage connected, and by rotating the shaft, the parallelogram linkage from a raised to a lowered position.
Nachteilig an dieser Vorrichtung ist unter anderem, daß in der geschlossenen Stellung der Schiebetür, d. h. in der angehobenen Position des Parallelogrammgestänges, die Hebel des Parallelogrammgestänges eine nahezu senkrechte Lage aufweisen und sich die Schiebewand somit in einer labilen Position befindet. Zur Stabilisierung ist die Schiebewand mittels an ihr befestigter Haken in Öffnungen eines Waggonrahmens fixiert, wobei die Haken durch an einer Riegelstange befindliche Riegel festgehalten werden.A disadvantage of this device is, inter alia, that in the closed position Sliding door, d. H. in the raised position of the parallelogram linkage, the lever of the Parallelogram linkage have an almost vertical position and thus the sliding wall is in an unstable position. To stabilize the sliding wall is attached to it Hooks fixed in openings in a wagon frame, with the hooks on a locking bar bars are held.
Weiters ist eine untere Ausstellvorrichtung für Schiebewände aus der DD 95 588 bekannt, bei welcher als Parallelführung dienende, im wesentlichen parallele Hebel über Hohlwellen miteinander gekoppelt sind. Nachteilig ist hier, daß die untere Parallelführung nur zur Führung der Schiebewand dient und keine abstützende Wirkung für die Schiebewand bietet. Die Schiebewand ist nur mittels Rollen in einer Führungsschiene an der Dachkonstruktion des Waggons gehalten ist, welche daher entsprechend massiv und stabil ausgeführt werden muß.Furthermore, a lower opening device for sliding walls is known from DD 95 588, at which serves as a parallel guide, essentially parallel levers with one another via hollow shafts are coupled. The disadvantage here is that the lower parallel guide only for guiding the sliding wall serves and has no supporting effect for the sliding wall. The sliding wall is only by means of Rolling is held in a guide rail on the roof structure of the wagon, which is why accordingly must be solid and stable.
Es ist eine Aufgabe der Erfindung, eine vollständige, möglichst reibungsarme Führung der Schiebewand aus ihrer Schließstellung bzw. in ihre Schließstellung zu ermöglichen.It is an object of the invention to provide a complete, low-friction guidance of the To allow sliding wall from its closed position or in its closed position.
Es ist weiters eine Aufgabe der Erfindung, eine untere Ausstellvorrichtung zu schaffen, bei der die Schiebewand mit geringem baulichen Aufwand möglichst stabil in ihrer Schließstellung gehalten ist.It is a further object of the invention to provide a lower opening device in which the Sliding wall is kept as stable as possible in its closed position with little structural effort.
Die gestellte Aufgaben werden mit einem Güterwaggengemäß dem Kennzeichen von Anspruch 1 gelöst.The tasks are carried out with a freight wagon according to the characterizing part of claim 1 solved.
In der geschlossenen Stellung der Schiebewand befindet sich das Parallelogrammgestänge in seiner abgesenkten, stabilen Position, wo es durch sein sowie das Eigengewicht der Schiebetür gehalten wird. Es sind daher für die Ausstellvorrichtung keine zusätzlichen Vorrichtungen zum Fixieren der Schiebewand in der abgesenkten Position notwendig, wie sie etwa bei der in der AT 246 773 B beschriebenen unteren Ausstellvorrichtungen verwendet werden.In the closed position of the sliding wall, the parallelogram linkage is in its lowered, stable position, where it is held by as well as the dead weight of the sliding door becomes. There are therefore no additional devices for fixing the Sliding wall in the lowered position is necessary, as is the case in AT 246 773 B described lower display devices can be used.
Weiters wird mit der erfindungsgemäßen Ausstellvorrichtung eine vollständige Führung der Schiebewand erzielt, die praktisch verschleißfrei ist, da die Schiebewand zum Öffnen angehoben und zum Schließen abgesenkt und dabei parallel zur Laufschiene bewegt wird.Furthermore, a complete guidance of the Sliding wall achieved that is practically wear-free because the sliding wall is raised to open and lowered to close and moved parallel to the running rail.
Ein weiterer Vorteil liegt noch darin, daß an der Schiebewand und/oder deren Rahmen angeordnete Dichtungen keinerlei Reibung unterworfen sind. Die Erfindung ist insbesondere für Güterwaggons geeignet und kann mit einer oberen Ausstellvorrichtung kombiniert werden, die Gegenstand der zeitranggleichen Patentanmeldung A 448/99 der Anmelderin ist.Another advantage is that the sliding wall and / or its frame arranged seals are not subject to any friction. The invention is particularly for Freight wagons and can be combined with an upper display device The subject-matter of patent application A 448/99 of the same priority is the applicant.
In vorteilhafter weiterer Ausgestaltung der Erfindung kann die Brücke den Rollenträger bilden, wodurch sich eine vereinfachte Konstruktion ergibt. In an advantageous further embodiment of the invention, the bridge can form the roller carrier, which results in a simplified construction.
Ferner kann jede Rolle eine konkave Lauffläche und die Laufschiene eine der Lauffläche angepaßte Laufbahn aufweisen. Dies ergibt außer einer exakten Führung beim Verschieben den Vorteil einer äußerst geringen Verschmutzungsanfälligkeit.Furthermore, each roller can have a concave tread and the running rail one adapted to the tread Have a career. In addition to exact guidance when moving, this gives the advantage of a extremely low susceptibility to contamination.
Weiters kann das Parallelogrammgestänge in der angehobenen Lage an einem Anschlag anschlagen, wodurch die der Offenstellung entsprechende Endlage des Parallelogrammgestänges genau definiert ist.Furthermore, the parallelogram linkage can strike a stop in the raised position, whereby the end position of the parallelogram linkage corresponding to the open position is precisely defined is.
Von Vorteil ist ferner, wenn am Rollenträger ein die Rolle oder deren Achsstummel übergreifender Bügel vorgesehen ist. Dies stellt eine Sicherung gegen Ausheben der Schiebewand dar.It is also advantageous if the roller carrier or the axle stub extends across the roller carrier Bracket is provided. This is a safeguard against lifting the sliding wall.
Zur weiteren Sicherung der Schiebewand beim Verschieben kann im Bereich der Ausnehmung eine Stützrolle und an der Schiebewand ein Bügel angebracht sein, der auf der Stützrolle abstützbar ist.To further secure the sliding wall when moving, a can in the region of the recess Support roller and a bracket attached to the sliding wall, which can be supported on the support roller.
Dabei kann der Bügel die Laufschiene untergreifen, um eine Sicherung gegen Ausheben zu erzielen.The bracket can reach under the running rail in order to secure it against lifting out.
Günstig dabei ist, wenn die Stützrolle an dem Anschlag angebracht ist, weil hierdurch ein vereinfachter Aufbau der Ausstellvorrichtung erzielt wird.It is advantageous if the support roller is attached to the stop, because this is a simplified structure of the display device is achieved.
Alternativ kann an der Schiebewand ein die Laufschiene untergreifender Bügel angebracht sein.Alternatively, a bracket under the running rail can be attached to the sliding wall.
Eine weitere Sicherung wird erreicht, wenn an der Laufschiene ein die Rolle oder deren Achsstummel übergreifender Bügel vorgesehen ist.A further securing is achieved if the roller or its on the running rail Axle stub overlapping bracket is provided.
Zur Entlastung der Ausstellvorrichtung in der Schließstellung der Schiebewand sowie zur Arretierung gegen seitliche Kräfte kann an der Schiebewand ein Widerlager vorgesehen sein, das bei geschlossener Schiebewand auf der Laufschiene aufliegt.To relieve the opening device in the closed position of the sliding wall and Locking against lateral forces, an abutment can be provided on the sliding wall closed sliding wall rests on the running rail.
Schließlich können die Rollen paarweise vorgesehen sein, und die Rollen sowie die ihnen zugeordneten Ausnehmungen eines Paares unterschiedlichen gegenseitigen Abstand bezüglich jedes anderen Paares aufweisen. Somit ist gewährleistet, daß beim Verfahren der Schiebewand mehr als zwei Rollen die Schiebewand tragen.Finally, the roles can be provided in pairs, and the roles and theirs associated recesses of a pair of different mutual spacing with respect to each other another pair. This ensures that the sliding wall moves more than two rollers carry the sliding wall.

Gemäß Fig. 1 und 2 ist die Schiebewand W eines Güterwaggons auf wenigstens zwei Rollen 6
gelagert und auf einer Laufschiene 5 verfahrbar (Fig. 2). Die Rollen 6 besitzen nach Art einer
Seilrolle eine konkave Lauffläche. Im Bereich jeder Rolle 6 bei geschlossener Schiebewand W ist am
Chassis des Güterwaggons ein Parallelogrammgestänge vorgesehen, das aus zwei Schwenkhebeln 2,
4 und einer Brücke 3 besteht, die zugleich als Rollenträger mit einem der Lauffläche der Rolle 6
angepaßten Auflager dient. Einer der Schwenkhebel 2 ist mit einer Welle 1 fest verbunden, die allen
Parallelogrammgestängen gemeinsam ist und bis zum Waggonende verläuft, wo sie an einen
herkömmlichen Betätigungsmechanismus, wie eine Handradbetätigung angeschlossen ist. Dieser
Betätigungsmechanismus ist mit einer oberen Ausstellvorrichtung gekoppelt.1 and 2, the sliding wall W of a freight wagon is on at least two
Durch Betätigen des Betätigungsmechanismus wird die Welle 1 verdreht, hierdurch das
Parallelogrammgestänge verschwenkt und die Brücke 3 angehoben sowie seitlich zu einer
Laufschiene 5 versetzt. Im Bereich der Welle 1 ist ein Anschlag 7 vorgesehen, der die Endlage des
benachbarten Schwenkhebels 2 definiert. In dieser angehobenen Lage der Schiebewand W fluchtet
die Brücke 3 samt Auflager mit der Laufschiene 5, die entlang dem Waggon durchgehend verläuft,
an den den Parallelogrammgestängen entsprechenden Stellen Ausnehmungen aufweist und eine der
Lauffläche der Rolle 6 angepaßte Laufbahn besitzt.By actuating the actuating mechanism, the shaft 1 is rotated, thereby the
Parallelogram linkage pivoted and the
Die Rollen 6 sitzen jeweils auf einem an der Schiebewand angebrachten Achsstummel. Zur
Sicherung der geschlossenen Schiebewand gegen Ausheben ist an der Brücke ein Bügel 8
vorgesehen, der den Achsstummel übergreift (Fig. 1). Zur Sicherung der geöffneten Schiebewand
W gegen Ausheben ist an dieser ein Bügel 9 angebracht, der die Laufschiene 5 untergreift (Fig. 2).
Der letztgenannte Bügel 9 dient zugleich der Abstützung der Schiebewand W beim Überfahren des
zwischen angehobener Brücke 3 und Laufschiene 5 bestehenden Spaltes. Zu diesem Zweck ist am
Anschlag 7 eine Stützrolle 10 angeordnet, die den Bügel 9 und somit die Schiebewand W abstützt.The
Schließlich ist die Schiebewand W in ihrem der Laufschiene benachbarten Bereich mit einem
Widerlager 11 versehen, das bei geschlossener Schiebewand W auf der Laufschiene 5 aufliegt (Fig.
1) und zur Entlastung der Ausstellvorrichtung in der Schließstellung der Schiebewand W sowie zur
Arretierung gegen seitliche Kräfte dient.Finally, the sliding wall W is in its area adjacent to the running rail with a
Vorzugsweise sind die Rollen 6 paarweise vorgesehen, wobei die Rollen 6 sowie die ihnen
zugeordneten Ausnehmungen in der Laufschiene 5 eines Paares unterschiedlichen gegenseitigen
Abstand bezüglich jedes anderen Paares aufweisen. Somit ist gewährleistet, daß beim Verfahren der
Schiebewand W mehr als zwei Rollen 6 die Schiebewand W tragen.The
Die Erfindung schafftes somit daß die Schiebewand oder Schiebetür
während des Öffnens und Schließens exakt und vollständig geführt ist. Infolge der
Schwenkbewegung des Parallelogrammgestänges sind die Reibungskräfte auf ein Minimum,
praktisch auf Null verringert. Vor allem sind Reibungen zwischen Rollen und Laufschiene bzw.
Rollenträger (Brücke 3) vermieden. Durch die besondere Ausgestaltung der Lauffläche der Rollen 6
und der Laufbahn der Laufschiene 5 besteht kaum Verschmutzungsgefahr. Die Schiebewand W ist
während des Öffnens, Schließens und Verfahrens mittels der Bügel 8 und 9 gegen Ausheben
gesichert. In der Schließstellung ist das Parallelogrammgestänge mit Hilfe des Widerlagers 11
entlastet. Eine allfällige Lippendichtung an der Schiebewand W im Bereich des Waggonbodens
unterliegt keinerlei Reibungskräften.The invention thus creates that the sliding wall or sliding door
is guided precisely and completely during opening and closing. As a result of
Swiveling movement of the parallelogram linkage keeps the frictional forces to a minimum,
practically reduced to zero. Above all, there is friction between the rollers and the running rail or
Roller carriers (bridge 3) avoided. Due to the special design of the running surface of the
