Abstract

Device for holding a cross traverse (1) supporting a rotary frame to a vehicle superstructure involves the traverse being held in a recess (2) with movement clearance. The recess at the bottom is limited by a securing bolt (4) connected to the vehicle superstructure by a mechanical spring (6). For altering the vertical opening of the recess, between the securing bolt and the vehicle superstructure one or more layer plates (8) can be inserted.

Description

Die Erfindung betrifft eine Vorrichtung zum Halten einer Quertraverse, die ein Drehgestell trägt, an einem Wagenkasten wobei die Quertraverse mit Bewegungsspielraum in einer Ausnehmung gehalten ist, die nach unten durch einen Sicherungsriegel begrenzt ist, der mit dem Wagenkasten in Verbindung steht.The invention relates to a device for holding a cross-beam, which carries a bogie, to a car body wherein the cross-beam is held with freedom of movement in a recess which is bounded below by a locking latch, which is in communication with the car body.

Eine gattungsgemäßen solche Vorrichtung zum Halten einer Quertraverse ist aus der DE 735 728 C bekannt. Zum technischen Hintergrund zählen außerdem die DE 195 44 030 A und DE 678 809 C .A generic such device for holding a crossbeam is from the DE 735 728 C known. The technical background also includes the DE 195 44 030 A and DE 678 809 C ,

Drehgestell, Quertraverse und Wagenkasten sind übliche Bestandteile eines Schienenfahrzeuges.Bogie, crossbeam and car body are common components of a rail vehicle.

Um einerseits den Torsionswinkel der Quertraverse zu begrenzen und um andererseits die Folgen eines Auflaufstoßes gering zu halten, ist schon vorgeschlagen worden, die Quertraverse elastisch mit dem Wagenkasten zu verbinden. Unter "Auflaufstoß" wird dabei ein Aneinanderstoßen von Wagen an den Puffern beim Bremsen oder Rangieren verstanden. Eine solche elastische Verbindung ermöglicht gegenüber einer auch üblichen Schweißverbindung eine Relativbewegung zwischen Quertraverse und Wagenkasten. Die elastische Verbindung ist jedoch verschleißanfällig.On the one hand to limit the torsion angle of the crossbeam and on the other hand to keep the consequences of a run-up impact low, it has been proposed to connect the crossbeam elastic to the car body. By "run-up shock" is meant a collision of carriages on the buffers during braking or maneuvering. Such elastic connection allows relative to a common weld also a relative movement between the crossbeam and the car body. However, the elastic connection is susceptible to wear.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zum Halten einer Quertraverse anzugeben, die mit einfachen und zuverlässigen Mitteln die Torsion der Quertraverse begrenzt und die mechanische Belastung durch einen Auflaufstoß vermindert.The invention has for its object to provide a device for holding a cross-beam, which limits the torsion of the cross-beam with simple and reliable means and reduces the mechanical load through a ramp.

Die Aufgabe wird gemäß der Erfindung dadurch gelöst, dass der Sicherungsriegel (4) mit dem Wagenkasten über eine mechanische Feder (6) in Verbindung steht.The object is achieved according to the invention in that the locking bolt (4) with the car body via a mechanical spring (6) is in communication.

Damit wird der Vorteil erzielt, dass sich die Quertraverse weder durch ihre eigene Torsion noch durch Kräfte aufgrund eines Auflaufstoßes vom Wagenkasten lösen kann. Darüber hin aus ist die Vorrichtung kaum störanfällig und einfach aufzubauen.Thus, the advantage is achieved that the crossbar can solve neither by their own torsion nor by forces due to an impact shock from the car body. Over there From the device is hardly susceptible to interference and easy to build.

Der Sicherungsriegel steht mit dem Wagenkasten über eine mechanische Feder in Verbindung. Diese Feder kann einen zum Bewegungsspielraum in der Ausnehmung hinzukommenden zusätzlichen Bewegungsspielraum der Quertraverse ermöglichen.The safety catch is connected to the car body via a mechanical spring. This spring can allow for the movement of additional space in the recess additional movement of the crossbeam.

Beispielsweise ist die mechanische Feder vorspannbar. Damit wird der Vorteil erzielt, dass die Bewegungsmöglichkeit der Quertraverse in einem vorgegebenen Rahmen einstellbar ist.For example, the mechanical spring is pretensioned. Thus, the advantage is achieved that the possibility of movement of the crossbeam is adjustable in a predetermined frame.

Beispielsweise sind zur Veränderung der vertikalen Öffnung der Ausnehmung zwischen dem Sicherungsriegel und dem Wagenkasten ein oder mehrere Schichtbleche einlegbar.For example, to change the vertical opening of the recess between the locking latch and the car body one or more laminations can be inserted.

Man geht also von einem zunächst relativ kleinen Bewegungsspielraum für die Quertraverse in der Ausnehmung aus. Durch das Einlegen von Schichtblechen kann die Vertikalausdehnung der Ausnehmung um definierte Schritte vergrößert werden. Man kann also vorteilhafterweise einen maximal möglichen Torsionswinkel der Quertraverse mit kleinen Toleranzen einstellen und gleichzeitig sicherstellen, dass die Quertraverse zuverlässig in der Ausnehmung gehalten ist, so dass bei einem Auflaufstoß die Verbindung zwischen Sicherungsriegel und Wagenkasten nur in einem ungefährlichen Ausmaß belastet wird.It is therefore assumed that there is initially a relatively small range of motion for the crosspiece in the recess. By inserting laminations, the vertical extent of the recess can be increased by defined steps. It is thus advantageously possible to set a maximum possible torsion angle of the crossbeam with small tolerances and at the same time to ensure that the crossbeam is reliably held in the recess, so that in a run-up joint, the connection between the safety catch and the body is loaded only to a harmless extent.

Der Sicherungsriegel ist beispielsweise mit einem mit dem Wagenkasten verbundenen Längsträger verbunden. Dadurch ist vorteilhafterweise eine stabile sichere Verbindung zwischen dem Sicherungsriegel und damit der Quertraverse einerseits und dem Wagenkasten andererseits gegeben.The securing bolt is connected, for example, to a longitudinal carrier connected to the vehicle body. As a result, a stable secure connection between the safety catch and thus the cross-beam on the one hand and the car body is on the other hand given advantageously.

Vorteilhafterweise wird die Quertraverse mit einfachen, zuverlässigen Mitteln bei einstellbarer Beweglichkeit gehalten Ein Ausführungsbeispiel für die Vorrichtung nach der Erfindung zum Halten einer Quertraverse an einem Wagenkasten wird anhand der Zeichnung näher erläutert:Advantageously, the crossbeam is held by simple, reliable means with adjustable mobility An embodiment of the device according to the invention for holding a cross-beam on a car body is explained in more detail with reference to the drawing:

Die gezeigte halbe Quertraverse 1 weist eine Anformung 1a mit rechteckigem Querschnitt auf. Diese Anformung 1a ist in einer Ausnehmung 2 gelagert, die nach oben durch einen Längsträger 3 und nach unten durch einen Sicherungsriegel 4 begrenzt ist. Der Sicherungsriegel 4 ist mit dem Längsträger 3 durch eine Schraube 5 verbunden. Der Längsträger 3 steht seinerseits mit dem nicht gezeigten Wagenkasten in Verbindung. Zwischen dem Kopf der Schraube 5 und dem Sicherungsriegel 4 ist eine mechanische Feder 6 gehalten durch einen Federteller 7 angeordnet, die einen Bewegungsspielraum für den Sicherungsriegel 4 und damit für die Quertraverse 1 vorgibt. Durch Festziehen der Schraube 5 kann die Vorspannung der Feder 6 und damit der Bewegungsspielraum eingestellt werden.The half-crossbeam 1 shown has a molding 1a with a rectangular cross-section. This Anformung 1a is mounted in a recess 2, which is bounded above by a side member 3 and down by a locking latch 4. The safety catch 4 is connected to the longitudinal member 3 by a screw 5. The longitudinal member 3 in turn is in communication with the carbody, not shown. Between the head of the screw 5 and the locking bolt 4 is a mechanical spring 6 held by a spring plate 7 is arranged, which defines a range of motion for the locking latch 4 and thus for the cross-beam 1. By tightening the screw 5, the bias of the spring 6 and thus the range of motion can be adjusted.

Durch einen zusätzlichen Bewegungspielraum, den die Anformung 1a in der Ausnehmung 2 hat, wenn die Ausnehmung 2 größer als die Anformung 1a ist, ist der Torsionswinkel der Quertraverse 1 weniger begrenzt als durch die Feder 6. Gleichzeitig kann sich die Quertraverse 1 infolge eines Auflaufstoßes in begrenztem Maße relativ zum Längsträger 3 und zum Sicherungsriegel 4 bewegen.By an additional range of motion, which has the Anformung 1a in the recess 2, when the recess 2 is greater than the Anformung 1a, the torsion angle of the crossbeam 1 is less limited than by the spring 6. At the same time, the crossbeam 1 due to an impact shock in move limited extent relative to the longitudinal member 3 and the locking latch 4.

Sowohl eine Beschädigung der Quertraverse 1 durch Torsion als auch ein schneller Verschleiß der gesamten Vorrichtung zum Halten der Quertraverse 1 durch einen Auflaufstoß wird mit der Vorrichtung nach der Erfindung verhindert.Both damage to the crossbeam 1 by torsion as well as rapid wear of the entire device for holding the crossbeam 1 by a run-up shock is prevented with the device according to the invention.

Zum Verändern des Bewegungsspielraums der Quertraverse 1 und damit des möglichen Torsionswinkels ist die Höhe der Ausnehmung 2 in einfacher Weise veränderbar gestaltet. Dazu sieht die Vorrichtung nach der Erfindung ein oder mehrere Schichtbleche 8 vor, die bei der Montage zwischen dem Sicherungsriegel 4 und dem Längsträger 3 eingelegt werden können. Es ist darauf zu achten, dass die Ausnehmung 2, die die Quertraverse 1 aufnimmt, zunächst möglichst klein ist. Ihre Höhe kann dann durch eingelegte Schichtbleche 8 vergrößert werden, bis der optimale Bewegungsspielraum für die Quertraverse 1 gegeben ist und damit auch der gewünschte maximale Torsionswinkel der Quertraverse 1 einzustellen ist. Insbesondere wird der vertikale Spielraum Z der Quertraverse 1 in der Ausnehmung 2 abhängig von den vorgegebenen maximalen Belastungen der Quertraverse 1 und der anderen Bauteile optimal eingestellt. Das ist aufgrund der einfach zu montierenden Schichtbleche 8 schnell und zuverlässig möglich. Die Quertraverse 1 wird mit einfachen Mitteln bei einstellbarer Beweglichkeit gehalten.To change the range of motion of the crossbeam 1 and thus the possible torsion angle, the height of the recess 2 is designed to be changeable in a simple manner. For this purpose, the device according to the invention provides one or more laminations 8, which can be inserted during assembly between the locking bolt 4 and the longitudinal member 3. It is make sure that the recess 2, which receives the crossbeam 1, initially as small as possible. Their height can then be increased by inserted laminations 8 until the optimal range of motion for the crossbeam 1 is given and thus also the desired maximum torsion angle of the crossbeam 1 is set. In particular, the vertical clearance Z of the cross-beam 1 in the recess 2 is optimally adjusted depending on the predetermined maximum loads of the cross-beam 1 and the other components. This is possible quickly and reliably due to the easy-to-install laminations 8. The crossbeam 1 is held by simple means with adjustable mobility.

Spiegelt man die Zeichnung an der Mittellinie 9, dann würde die Zeichnung die gesamte Quertraverse 1 mit zwei Vorrichtungen zur Halterung darstellen. Die Quertraverse 1 überspannt den Boden eines Schienenfahrzeugs quer zur Fahrtrichtung.Reflecting the drawing at the center line 9, then the drawing would represent the entire cross-beam 1 with two devices for mounting. The cross-beam 1 spans the floor of a rail vehicle transversely to the direction of travel.
