Abstract

The method uses an electronic data processor to evaluate date collected by measuring units, and to control actuator elements. The acceleration of a wheel set (3) horizontally at right angles to its direction of travel, is measured by a device (9), and is used to determine a turning momentum, which is imprinted upon the wheel set about its vertical axis. Measured angular acceleration of the wheel set about its vertical axis is used to determine a force, which is imprinted upon the wheel set horizontally at right angles to its direction of travel.

Description

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Stabilisierung des Wellenlaufes von Eisenbahnradsätzen.
Ein Radsatz besitzt infolge seiner konischen Profile die vorteilhafte Eigenschaft, sich unter folgenden Voraussetzungen im Bogen selbst bogenradial einzustellen:

  • Die Profilpaarung muß die zur Erzeugung der nötigen Rollradiendifferenz zwischen innerem und äußerem Rand erforderliche Querverschiebung zulassen; dies ist bei der Standardkombination S 1002/UIC 60/1 : 40 bis zu Bogenradien von etwa 150 m gegeben.
  • Die Wendebewegung des Radsatzes darf nicht behindert sein.
The invention relates to a method and an apparatus for stabilizing the shaft running of railway wheel sets.
Due to its conical profile, a wheel set has the advantageous property of being self-radial in the arc under the following conditions:
  • The profile pairing must allow the transverse displacement required to generate the required difference in rolling radii between the inner and outer edges; this is the case with the standard combination S 1002 / UIC 60/1: 40 up to an arc radius of around 150 m.
  • The turning movement of the wheelset must not be hindered.

Leider hat der Radsatz wegen der konischen Profile auch die Eigenschaft, daß der Radsatzlauf in der Geraden bereits bei sehr geringen Geschwindigkeiten instabil wird (der Radsatz allein bei der o.g. Profilpaarung etwa bei 20 km/h). Dabei bewegt sich der Radsatz auf einer Wellenbahn durch den Spurkanal des Gleises (Radsatz-Wellenlauf). Unruhiger Fahrzeuglauf, Verschleiß an Rädern und Schienen und Rollgeräusche sind die Folge.
Zur Stabilisierung bindet man den Radsatz üblicherweise - mehr oder weniger steif - an den Drehgestellrahmen an (Radsatzführung) und verhindert somit die Wendebewegung. Leider zerstört man auf diese Weise den erstgenannten Selbstlenkungseffekt; Verschleiß und Geräuschemission sind die Folge. Drehgestelle mit Losrädern gewährleisten zwar systembedingt die Laufstabilität bis zu sehr hohen Geschwindigkeiten, besitzen aber nicht die Eigenschaften der Selbstzentrierung und selbständigen bogenradialen Einstellung des Radsatzes und sind daher einem erhöhten Verschleiß unterworfen.
Auch für Einzelachs-Fahrwerke sind eine Reihe von Lösungen vorgeschlagen worden, um den geschilderten Mängeln abzuhelfen.
Einzelachs-Fahrwerke mit Radsätzen können beispielsweise mit Hilfe einer passiven Einrichtung, z.B. durch Abgreifen der Winkelstellung zweier benachbarter Wagenkästen, bogenradial eingestellt werden. So zeigt die CH-PS 399 522 die Einstellung eines Einzelachs-Fahrwerkes über den Knickwinkel zwischen zwei Wagenkästen.Unfortunately, because of the conical profiles, the wheelset also has the property that the wheelset run in the straight line becomes unstable even at very low speeds (the wheelset alone with the above profile pairing at around 20 km / h). The wheelset moves on a wave path through the track channel of the track (wheelset waves). This results in restless vehicle running, wear on wheels and rails and rolling noises.
For stabilization, the wheelset is usually connected - more or less stiffly - to the bogie frame (wheelset guide) and thus prevents the turning movement. Unfortunately, this destroys the first-mentioned self-steering effect; Wear and noise emissions are the result. Bogies with idler gears ensure running stability up to very high speeds due to the system, but they do not have the properties of self-centering and independent arc-radial adjustment of the wheel set and are therefore subject to increased wear.
A number of solutions have also been proposed for single-axle undercarriages to remedy the shortcomings described.
Single-axle undercarriages with wheelsets can be set radially for example with the aid of a passive device, for example by tapping the angular position of two adjacent car bodies. For example, CH-PS 399 522 shows the setting of a single-axle chassis via the articulation angle between two car bodies.

Bekannt sind weiterhin Fahrwerke, deren Lösräder elektromechanisch gekoppelt sind, um eine Stabilisierung und gleichzeitige bogenradiale Einstellung im Bogen zu erzielen
(EP 0770 533 A1, EP 0785 123 A1, EP 0936 125 A2). Bisher ist allerdings nicht nachgewiesen worden, ob die genannten Lösungen dem gestellten Anspruch gerecht werden.
Durch die DE 33 31 559 C2 ist ferner eine Achssteuerung für zwei- oder mehrachsige Schienenfahrzeuge bekannt, die gegensinnige Wendebewegungen und Querbewegungen der Radsätze ermöglichen soll und bei der die beiden Achslager eines Radsatzes mit den jeweils gegenüberliegenden Achslagern des anderen Radsatzes durch ein hydraulisches System untereinander verbunden sind und Arbeitsräume verschiedener Hydraulikzylinder in Wirkverbindung stehen. Eine aktive Steuerung oder Regelung ist hier nicht vorgesehen.
Schließlich ist durch die DE 31 19 164 C2 eine aktive Steuerung der Radsätze in einem Drehgestell bekanntgeworden, die vor allem bei Kurvenfahrt einen konstanten Abstand des Spurkranzes von der Schieneninnenkante sichern soll. Es geht hier um ein Drehgestell mit radial einstellbaren Radsätzen, die zur aktiven Steuerung durch eine Pumpe über eine Steuereinheit beaufschlagbar sind, wobei die Steuereinheit mit einem Geber zusammenwirkt, welcher die Abstände von der Schienenkante zum Spurkranz verfolgt. Das Spiel zwischen Schienenkante und Spurkranz wird in bekannter Weise durch einen Geber gemessen und nach Soll-Ist-Wert-Vergleich in der Steuereinheit zur Regelung der hydraulischen Kolbenzylinder-Einheit verarbeitet. Bisher ist nicht bekanntgeworden, ob die in dieser Patentschrift beschriebene aktive Steuerung der Radsätze auch in der Geraden bei hohen Geschwindigkeiten einen stabilen Radsatzlauf gewährleistet, abgesehen davon, daß diese Lösung für ein bestimmtes Luftfedergestell vorgeschlagen wurde.
Aufgabe der Erfindung ist daher die Entwicklung eines Systems zur Erreichung eines stabilen Radsatzlaufes in der Geraden in Verbindung mit einer vollständig bogenradialen Einstellung des Radsatzes im Bogen, das mit einer neuartigen Steuerungs- oder Regelgröße arbeitet und eine zuverlässige Erkennung des Wellenlaufes des Radsatzes als Eingangsgröße des Systems aufweist.Trolleys are also known, the release wheels of which are electromechanically coupled in order to achieve stabilization and simultaneous arc radial adjustment in the arc
(EP 0770 533 A1, EP 0785 123 A1, EP 0936 125 A2). So far, however, it has not been proven whether the solutions mentioned meet the demand.
From DE 33 31 559 C2 an axle control for biaxial or multiaxial rail vehicles is also known, which is intended to enable opposite turning movements and transverse movements of the wheel sets and in which the two axle bearings of one wheel set are connected to one another by a hydraulic system with the opposite axle bearings of the other wheel set are and working spaces of different hydraulic cylinders are operatively connected. Active control or regulation is not provided here.
Finally, DE 31 19 164 C2 has disclosed active control of the wheel sets in a bogie, which is intended to ensure a constant distance of the wheel flange from the inside edge of the rail, especially when cornering. This is about a bogie with radially adjustable wheel sets which can be acted upon by a pump for active control by a control unit, the control unit cooperating with an encoder which tracks the distances from the rail edge to the wheel flange. The play between the rail edge and the flange is measured in a known manner by an encoder and processed in the control unit for regulating the hydraulic piston-cylinder unit after a comparison of the target and actual value. So far it has not become known whether the active control of the wheel sets described in this patent ensures stable wheel set running even in the straight line at high speeds, apart from the fact that this solution has been proposed for a specific air spring frame.
The object of the invention is therefore to develop a system for achieving a stable wheel set run in the straight line in connection with a completely arc-radial setting of the wheel set in the curve, which works with a novel control or regulating variable and a reliable detection of the wave run of the wheel set as the input variable of the system having.

Gemäß der Erfindung wird dies durch die Merkmale der Patentansprüche 1, 2 und 5 erreicht. Vorteilhafte Weiterbildungen sind Gegenstand der auf die Ansprüche 1 und 2 rückbezogenen Ansprüche.
Mit Hilfe eines aktiven Systems wird die Querbeschleunigung des Radsatzes gemessen und daraus durch geeignete numerische Aufbereitung ein Wendemoment berechnet, das dem Radsatz aufgeprägt wird und so den Radsatzlauf stabilisiert.
Das System kann auch in der Wirkungsweise umgekehrt werden, indem man in der oben beschriebenen Weise aus der gemessenen Wendewinkelbeschleunigung des Radsatzes eine Querkraft berechnet, die dem Radsatz aufgeprägt wird.
In beiden Fällen darf die Wendebewegung des Radsatzes nicht behindert werden; die Radsatzführung überträgt nur Längskräfte (Antriebs- und Bremskräfte), aber keine Wendemomente.
Bei einer Ausgestaltung ausschließlich als Steuerungssystem verwendet das System als Eingangsgröße die Querbeschleunigung und benötigt keine Rückführung der Ausgangsgröße. Durch die Einfachheit der Steuerung ist die Erfindung relativ preiswert und wenig fehleranfällig.
Vorteile gegenüber bisher bekannten Lösungen ergeben sich sowohl beim Einsatz im Drehgestell als auch im Einzelachs-Fahrwerk.
Beim Einsatz im Drehgestell gewährleistet sie einen stabilen Radsatzlauf in der Geraden bis zu hohen Geschwindigkeiten und läßt gleichzeitig die bogenradiale Einstellung der Radsätze im Bogen zu. According to the invention, this is achieved by the features of claims 1, 2 and 5. Advantageous further developments are the subject of the claims referring back to claims 1 and 2.
With the help of an active system, the lateral acceleration of the wheelset is measured and a turning moment is calculated from it by means of suitable numerical processing, which is impressed on the wheelset and thus stabilizes the wheelset run.
The system can also be reversed in operation by calculating a lateral force from the measured turning angle acceleration of the wheelset in the manner described above, which is applied to the wheelset.
In both cases, the turning movement of the wheelset must not be hindered; the wheelset guide only transfers longitudinal forces (drive and braking forces), but no turning moments.
In the case of a configuration exclusively as a control system, the system uses the lateral acceleration as an input variable and does not require any feedback of the output variable. Due to the simplicity of the control, the invention is relatively inexpensive and less prone to errors.
There are advantages over previously known solutions both when used in the bogie and in the single-axle chassis.
When used in the bogie, it guarantees stable wheel set running in the straight line up to high speeds and at the same time allows the wheel sets in the curve to be set radially.

Durch die bogenradiale Einstellung wird die Querkraftsumme des führenden Radsatzes im Drehgestell deutlich reduziert. Diese ist insbesondere in Verbindung mit einer Neigeeinrichtung im Drehgestell oft das kritische Kriterium für die maximal zulässige Fahrgeschwindigkeit im Bogen; daher besitzt die Erfindung gerade in Kombination mit einer Neigetechnik erhebliche Vorteile. Auch Geräuschemission im Bogen und Verschleiß werden stark reduziert.
Im Einzelachs- Fahrwerk beseitigt die Erfindung den Nachteil der im Stand der Technik genannten, relativ einfachen passiven Systeme, daß sie bei Bogenein- und -ausfahrt Fehlsteuersignale produzieren, die hier kurzfristig zu erhöhtem Verschleiß führen. Die im Stand der Technik erwähnten aktiven Systeme sind nur für Einachsfahrwerke einsetzbar und benötigen zudem eine vergleichsweise aufwendige Regelung der elektromechanischen Kopplung. Gegenüber diesen Systemen wird die Regelung bzw. Steuerung vereinfacht.The radial radial adjustment significantly reduces the total shear force of the leading wheelset in the bogie. In conjunction with a tilting device in the bogie, this is often the critical criterion for the maximum permitted travel speed in the curve; Therefore, the invention has considerable advantages, especially in combination with a tilting technique. Noise emissions in the bow and wear are also greatly reduced.
In single-axle undercarriage, the invention eliminates the disadvantage of the relatively simple passive systems mentioned in the prior art that they produce false control signals when entering and exiting the bend, which leads here to increased wear in the short term. The active systems mentioned in the prior art can only be used for single-axle chassis and also require a comparatively complex control of the electromechanical coupling. The regulation or control is simplified compared to these systems.

    For each wheel set, the stabilization system consists of an acceleration sensor 9, two actuators 10 arranged in the longitudinal direction and acting in phase opposition with the associated energy supply and an electronic data processing system.
