Description

Die Erfindung betrifft ein Schienenfahrzeug mit Drehgestellen, mit den Merkmalen des Oberbegriffs des Anspruchs 1.The invention relates to a rail vehicle with bogies, with the features of the preamble of claim 1.

Solche Schienenfahrzeuge sind bekannt.Such rail vehicles are known.

Der Gradient der Luftfederkennlinien kann durch Zusatzvolumina verändert werden, die in Form von Behältern über Leitungen mit dem jeweiligen Balg verbunden sind, oder durch entsprechende konstruktive Gestaltung der Balgplatte oder Federauflage geschaffen werden (vgl. Hanneforth, Fischer; Laufwerke, Berlin 1986).The gradient of the air spring characteristics can be changed by additional volumes, which are connected to the respective bellows in the form of containers via lines, or by appropriate design of the bellows plate or spring support (cf.Hanneforth, Fischer; Laufwerke, Berlin 1986).

Beide Bälge eines Drehgestells sind üblicherweise über ein Differenzdruckventil (DE-AS 10 88 086) miteinander verbunden, um das Auftreten unzulässiger Radlastunterschiede bei einseitigem Druckverlust zu verhindern, wobei die bei Bogenfahrt auftretenden Druckunterschiede zwischen bogeninnerem und bogenäußerem Luftfederbalg jedoch zugelassen sind. Eine wünschenswerte Steigerung des bogenäußeren Drucks würde eine Außerkraftsetzung der Sicherheitsfunktion des Differenzdruckventils erfordern.Both bellows of a bogie are usually connected to each other via a differential pressure valve (DE-AS 10 88 086) in order to prevent the occurrence of impermissible wheel load differences with one-sided pressure loss, whereby the pressure differences that occur between the inside and outside of the air spring bellows when traveling through bends are permitted. A desirable increase in outside pressure would require the safety function of the differential pressure valve to be overridden.

Aufgabe der Erfindung ist es, die Sekundärfederung entsprechend vorbestimmter Kennziffern regelbar zu machen und durch eine Beeinflussung des Federvolumens den bei unausgeglichenen Querbeschleunigungen auftretenden Wankbewegungen durch eine Asymmetrie der Abstützcharakteristik entgegenzuwirken.The object of the invention is to make the secondary suspension controllable in accordance with predetermined reference numbers and to counteract the roll movements occurring in the case of unbalanced transverse accelerations by an asymmetry of the support characteristic by influencing the spring volume.

Diese Aufgabe wird mit den im kennzeichnenden Teil des Anspruchs 1 genannten Merkmalen gelöst. Fortbildungen und besondere Ausführungen der Erfindung sind in den weiteren Ansprüchen umfaßt.This task is carried out in the characteristic part of the Features mentioned claim 1 solved. Developments and special embodiments of the invention are included in the further claims.

Erfindungsgemäß sind den Torusbälgen eines Drehgestells mit Luftfederung als Sekundärfederung Zusatzvolumina zugeordnet, wobei zwischen den Torusbälgen und den Zusatzvolumina Dreiwegeventile angeordnet sind.According to the invention, additional volumes are assigned to the torus bellows of a bogie with air suspension as secondary suspension, three-way valves being arranged between the torus bellows and the additional volumes.

Über die Dreiwegeventile können die Zusatzvolumina vom zugehörigen Torusbalg getrennt und gleichzeitig dem zweiten Torusbalg des Drehgestells über eine Verbindungsleitung zugeschaltet werden.The additional volumes can be separated from the associated toroidal bellows via the three-way valves and simultaneously connected to the second toroidal bellows of the bogie via a connecting line.

Das Dreiwegeventil wird vorteilhafterweise über ein Gestänge betätigt, wobei es so ausgeführt sein kann, daß es die Relativbewegungen des Wagenkastens quer zum Drehgestellrahmen überträgt. Dabei ist es sinnvoll, wenn Gestänge und Ventilcharakteristik einen einstellbaren Totweg ermöglichen. Das Gestänge kann hierbei zum Beispiel unmittelbar auf das Küken des Ventils wirken.The three-way valve is advantageously operated via a linkage, and it can be designed so that it transmits the relative movements of the car body transversely to the bogie frame. It makes sense if the linkage and valve characteristics enable an adjustable dead travel. For example, the linkage can act directly on the valve plug.

Die Zusatzvolumina sind entweder in zuschaltbaren Druckbehältern oder in zuschaltbaren Hohlräumen im Wagenkasten oder im Drehgestell angeordnet.The additional volumes are arranged either in switchable pressure vessels or in switchable cavities in the car body or in the bogie.

Im Folgenden wird die Erfindung anhand von Zeichnungen beispielhaft näher beschrieben. Dabei zeigen:

The invention is described in more detail below by way of example using drawings. Show:
Fig. 1)
a schematic representation of the secondary suspension of a rail vehicle when driving straight ahead;
Fig. 2)
is a schematic representation of the secondary suspension of a rail vehicle during the bend.

Die Sekundärfederung gemäß Fig. 1 und Fig. 2, bestehend aus als Torusbälgen 2, 3 mit angeschlossenen Zusatzvolumina 6, 7 ausgeführter Luftfederung, ist in üblicher Weise zwischen Drehgestell und Wagenkasten angeordnet. Die Torusbälge 2, 3 sind untereinander durch eine Leitung 10 verbunden, wobei ein Differenzdruckventil 1 als Sicherung gegen zu großen Druckabfall eines Torusbalges 2, 3 zwischengeschaltet ist. Die Torusbälge 2, 3 sind über weitere Leitungen 11, 12 mit Zusatzvolumina 6, 7 verbunden, die in Druckbehältern oder Hohlräumen des Schienenfahrzeugs angeordnet sein können. Zwischen den Torusbälgen 2, 3 und den Zusatzvolumina 6, 7 sind Dreiwegeventile 4, 5 angeordnet, wobei sich eine weitere Leitung 17 zwischen den beiden Dreiwegeventilen 4, 5 befindet. Die Dreiwegeventile 4, 5 sind über ein Gestänge 8 am Wagenkasten 9 angelenkt, wobei mittels des Gestänges 8 bestimmte Wege der Dreiwegeventile 4, 5 freigegeben, bzw. gesperrt werden, indem durch das Gestänge 8 das Küken im Ventil gedreht wird. Durch entsprechende Anordnungen der Durchflußöffnungen oder durch ein vorgesehenes Spiel des Gestänges kann ein Totweg definiert werden. Die Torusbälge sind in üblicher Weise über Anschlußleitungen 13, 14 mit einer Druckluftversorgung verbunden.The secondary suspension according to Fig. 1 and Fig. 2, consisting of as bellows 2, 3 with connected Additional volumes 6, 7 designed air suspension is arranged in the usual way between bogie and car body. The torus bellows 2, 3 are connected to one another by a line 10, a differential pressure valve 1 being interposed as a safeguard against excessive pressure drop in a torus bellows 2, 3. The torus bellows 2, 3 are connected via additional lines 11, 12 to additional volumes 6, 7 which can be arranged in pressure vessels or cavities in the rail vehicle. Three-way valves 4, 5 are arranged between the torus bellows 2, 3 and the additional volumes 6, 7, a further line 17 being located between the two three-way valves 4, 5. The three-way valves 4, 5 are articulated via a linkage 8 to the car body 9, whereby certain paths of the three-way valves 4, 5 are released or blocked by means of the linkage 8, in that the linkage 8 rotates the plug in the valve. A dead path can be defined by appropriate arrangements of the flow openings or by an intended play of the linkage. The torus bellows are connected in the usual way to a compressed air supply via connecting lines 13, 14.

Bei der Geradeausfahrt gemäß Fig. 1 sind die zugehörigen Zusatzvolumina 6, 7 den Torusbälgen 2, 3 zugeschaltet. Die Dreiwegeventile 4, 5 sperren die Leitung 17, die sie miteinander verbindet. In der Bogenfahrt gemäß Fig. 2 dagegen lenkt der Wagenkasten 9 gegenüber dem Drehgestell aus und das Gestänge 8 betätigt die Dreiwegeventile 4, 5 derart, daß das Zusatzvolumen 6 von dem Torusbalg 2 abgekoppelt wird, in dessen Richtung die Querbeschleunigung aq wirkt. Gleichzeitig wird die Leitung 17 zwischen den Dreiwegeventilen 4, 5 geöffnet, so daß nun beide Zusatzvolumina 6, 7 mit dem anderen Torusbalg 3 zusammengeschlossen sind.1, the associated additional volumes 6, 7 are connected to the torus bellows 2, 3. The three-way valves 4, 5 block the line 17 which connects them to one another. 2, on the other hand, the car body 9 deflects relative to the bogie and the linkage 8 actuates the three-way valves 4, 5 in such a way that the additional volume 6 is decoupled from the toroidal bellows 2, in the direction of which the transverse acceleration a q acts. At the same time, the line 17 between the three-way valves 4, 5 is opened, so that both additional volumes 6, 7 are now connected to the other toroidal bellows 3.
