Abstract
Description
Diese Erfindung betrifft eine Queraufhängung für Schienenfahrzeuge.This invention relates to a transverse suspension for rail vehicles.
Die Queraufhängung eines Schienenfahrzeugs wird herkömmlich üblicherweise von Vorrichtungen mit Schrauben- oder Gummifedern gebildet, die parallel zur Sekundäraufhängung zwischen dem Aufbau eines jeden Drehgestells und dem Aufbau des Fahrzeugs wirken.The transverse suspension of a rail vehicle is traditionally usually formed by devices with helical or rubber springs acting parallel to the secondary suspension between the body of each bogie and the body of the vehicle.
Diese Lösungen sind normalerweise mit einer relativen Verschiebung zwischen dem Aufbau und dem Drehgestell verbunden, die Anlaß für ein Spiel infolge einer Abnützung und der Übertragung von Schwingungen ist.These solutions are usually associated with a relative displacement between the body and the bogie, which gives rise to play due to wear and the transmission of vibrations.
Um dieses Problem zu vermeiden, besteht der Gegenstand dieser Erfindung in einer Aufhängung für Schienenfahrzeuge, dadurch gekennzeichnet, daß sie einen Drehstab, der entweder einerseits am Aufbau oder am Drehgestell befestigt ist, sowie eine Einrichtung aufweist, um den Drehstab andererseits mit dem Drehgestell oder dem Aufbau zu verbinden.In order to avoid this problem, the subject of this invention is a suspension for rail vehicles, characterized in that it comprises a torsion bar which is fixed either to the body or to the bogie on the one hand, and a device for connecting the torsion bar to the bogie or to the body on the other hand.
Der Vorteil dieser Lösung besteht darin, daß allgemein die Relativbewegungen zwischen dem Aufbau und dem Drengestell, die Querkräfte zwischen dem Aufbau und dem Drehgestell aufgebracht werden, ohne daß eine relative Verschiebung und die dadurch hervorgerufenen Probleme auftreten.The advantage of this solution is that the relative movements between the body and the bogie and the transverse forces between the body and the bogie are generally applied without causing relative displacement and the problems caused by it.
Gemäß einer bevorzugten Ausführungsform der Erfindung wird der Drehstab parallel zur Längsachse des Fahrzeugs angeordnet, wobei seine Enden fest in Befestigungen sitzen, die am Aufbau angebracht sind, und wobei die Verbindungseinrichtung einen im wesentlichen vertikalen Hebel, von dem ein Ende mit dem Drehstab verkeilt ist, sowie eine Welle enthält, die im wesentlichen parallel zur Querachse des Fahrzeugs liegt, wobei ihre Enden mit dem Rahmen des Drehgestells bzw. mit dem anderen Ende des Hebels gelenkig verbunden sind.According to a preferred embodiment of the invention, the torsion bar is arranged parallel to the longitudinal axis of the vehicle, with its ends firmly seated in fastenings provided on the body, and the connecting device comprises a substantially vertical lever, one end of which is keyed to the torsion bar, and a shaft which is substantially parallel to the transverse axis of the vehicle, its ends being hinged to the frame of the bogie and to the other end of the lever, respectively.
Die Erfindung wird nun anhand eines nichteinschränkenden Beispiels und den beiliegenden Zeichnungen ausführlich beschrieben, in denen zeigt:The invention will now be described in detail by way of non-limiting example and with reference to the accompanying drawings, in which:
Fig. 1 den vereinfachten Schnitt durch einen Teil eines Schienenfahrzeugs, das mit einer Queraufhängung gemäß der Erfindung ausgestattet ist; undFig. 1 shows a simplified section through part of a rail vehicle equipped with a transverse suspension according to the invention; and
Fig. 2 den Schnitt entlang der Achse II-II von Fig. 1.Fig. 2 shows the section along the axis II-II of Fig. 1.
Im Zusammenhang mit den Zeichnungen sind der untere Teil des Aufbaus eines Schienenfahrzeugs allgemein mit der Bezugsziffer 1 und ein Teil des Aufbaus von einem Drehgestell mit der Bezugsziffer 2 versehen, wobei dazwischen eine Queraufhängung 3 gemäß der Erfindung liegt. Es sei darauf hingewiesen, daß jedem Fahrzeugdrehgestell normalerweise zwei Aufhängungen 3 zugeordnet und symmetrisch an gegenüberliegenden Seiten nahe den Seiten des Aufbaus 1 angeordnet sind.In connection with the drawings, the lower part of the body of a rail vehicle is generally indicated by the reference numeral 1 and a part of the body of a bogie is indicated by the reference numeral 2, with a transverse suspension 3 according to the invention located therebetween. It should be noted that each vehicle bogie is normally associated with two suspensions 3 and arranged symmetrically on opposite sides near the sides of the body 1.
Die Queraufhängung 3 enthält im wesentlichen einen Drehstab 4, der parallel zur Längsachse des Fahrzeugs liegt, wobei seine Enden fest in einem Paar von Befestigungen 5 sitzen, die von einem Träger 6 des Aufbaus 1 getragen werden. Das obere Ende eines Hebels 7, der im wesentlichen senkrecht liegt, ist mit dem Drehstab 4 verkeilt, wobei sein unteres Ende mit einem Ende einer Welle 8 gelenkig verbunden ist, die im wesentlichen parallel zur Querachse des Fahrzeugs liegt. Das entgegengesetzte Ende der Welle 8 ist bei der Bezugsziffer 9 mit dem Rahmen des Drehgestells 2 gelenkig verbunden.The transverse suspension 3 essentially comprises a torsion bar 4 lying parallel to the longitudinal axis of the vehicle, with its ends fixedly fitted in a pair of mountings 5 carried by a beam 6 of the body 1. The upper end of a lever 7 lying substantially vertically is keyed to the torsion bar 4, with its lower end being articulated to one end of a shaft 8 lying substantially parallel to the transverse axis of the vehicle. The opposite end of the shaft 8 is articulated to the frame of the bogie 2 at reference numeral 9.
Im Betrieb wirken den relativen Querbewegungen zwischen dem Aufbau 1 und dem Drehgestell 2 entsprechende Torsionsdeformationen des Stabs 4 elastisch entgegen, die von der Übertragung stammen, die vom Hebel 7 und der Welle 8 gebildet wird.During operation, the relative transverse movements between the body 1 and the bogie 2 are elastically counteracted by corresponding torsional deformations of the rod 4, which originate from the transmission formed by the lever 7 and the shaft 8.
Die Aufhängung 3 kann weiters mit einem Querstoßdämpfer 10 ausgestattet sein, der zwischen dem Aufbau 1 und dem Rahmen des Drehgestells 2 liegt, wie dies Fig. 1 zeigt.The suspension 3 can further be equipped with a transverse shock absorber 10 which is located between the body 1 and the frame of the bogie 2, as shown in Fig. 1.
