Description

Die Erfindung betrifft eine Sekundärfeder zur Abfederung eines Wagenkastens eines Schienenfahrzeugs auf einem Fahrwerk des Schienenfahrzeugs und ein Schienenfahrzeug.The invention relates to a secondary spring for cushioning a car body of a rail vehicle on a chassis of the rail vehicle and a rail vehicle.

Sekundärfedern, beispielsweise ausgebildet als Uhrglasfedern, sind zwischen einem Fahrwerk und einem Wagenkastens eines Schienenfahrzeugs angeordnet, um den Wagenkasten auf dem Fahrwerk abzufedern. Sie dienen der Übertragung von Traktions-, Vertikal- und Seitenkräften zwischen Fahrwerk und Wagenkasten. Dazu sind sie üblicherweise mit dem Wagenkasten und mit dem Fahrwerk verschraubt. Um die Bewegungen zwischen dem Wagenkasten und dem Fahrwerk zu begrenzen, sind zusätzlich zueinander komplementäre, mechanische Endanschläge in Form von Vertikal- und Horizontalanschlägen am Wagenkasten und am Fahrwerk vorgesehen. Diese werden auch als Quer- und Hochanschläge bezeichnet. Somit werden Kollisionen und damit Beschädigungen von Fahrwerkskomponenten oder von Komponenten des Wagenkastens vermieden.Secondary springs, for example in the form of watch glass springs, are arranged between the undercarriage and the body of a rail vehicle in order to cushion the body on the undercarriage. They are used to transmit traction, vertical and lateral forces between the chassis and the body. For this purpose, they are usually bolted to the body and to the chassis. In order to limit the movements between the car body and the chassis, complementary mechanical end stops in the form of vertical and horizontal stops on the car body and on the chassis are additionally provided. These are also known as cross and vertical stops. Collisions and thus damage to chassis components or components of the body are avoided.

Ein- und mehrteilige Sekundärfedern sind seit langem beklannt. Die Offenlegungsschriften AT 511 876 A1 und FR 2 896 220 A1 zeigen zweistufige Sekundärfedern mit in Reihe angeordneten, unterschiedlichen Federn. Die Offenlegungsschrift EP 2 000 383 A2 lehrt parallel zueinander angeordnete und somit verschachtelte Federn mit unterschiedlichen Quersteifigkeiten. Die EP 2 251 562 A1 offenbart eine mehrteilige Luftfederanordnung für rahmenlose Drehgestelle, die einen vorgegebenen Federkomfort selbst bei entleerter Luftfeder gewährleisten soll.Single and multi-part secondary springs have been covered for a long time. The disclosures AT 511 876 A1 and FR 2 896 220 A1 show two-stage secondary springs with different springs arranged in series. The disclosure EP 2 000 383 A2 teaches springs arranged parallel to one another and thus nested with different transverse stiffnesses. The EP 2 251 562 A1 discloses a multi-part air spring assembly for frameless bogies, which is intended to ensure a predetermined spring comfort even when the air spring is empty.

Der Erfindung liegt die Aufgabe zugrunde, Beschädigungen von Fahrwerkskomponenten oder von Komponenten des Wagenkastens auf einfache und kostengünstige Art und Weise zu vermeiden.The invention has for its object to avoid damage to chassis components or components of the car body in a simple and inexpensive manner.

Gelöst wird die Aufgabe durch den Gegenstand des unabhängigen Patentanspruchs 1. Weiterbildungen und Ausgestaltungen der Erfindung finden sich in den Merkmalen der abhängigen Patentansprüche wieder.The object is achieved by the subject matter of independent patent claim 1. Further developments and refinements of the invention can be found in the features of the dependent patent claims.

Eine erfindungsgemäße Sekundärfeder zur Abfederung eines Wagenkastens eines Schienenfahrzeugs auf einem Fahrwerk des Schienenfahrzeugs, insbesondere auf einem Drehgestell des Schienenfahrzeugs, umfasst einen ersten und zumindest einen weiteren, zweiten Abschnitt, welcher erste Abschnitt entlang einer vorgegebenen Achse steif und orthogonal zur vorgegebenen Achse federnd ausgebildet ist und welcher zweite Abschnitt orthogonal zur vorgegebenen Achse steif und entlang der vorgegebenen Achse federnd ausgebildet ist. Darüber hinaus umfasst die Sekundärfeder zumindest einen Horizontalanschlag, welcher so an der Sekundärfeder angeordnet ist, dass eine Kraft, welche orthogonal zur vorgegebenen Achse auf den Horizontalanschlag einwirkt, zwischen dem ersten und dem zweiten Abschnitt in die Sekundärfeder eingeleitet wird.A secondary spring according to the invention for cushioning a car body of a rail vehicle on a chassis of the rail vehicle, in particular on a bogie of the rail vehicle, comprises a first and at least one further, second section, the first section being stiff and orthogonal to the predetermined along a predetermined axis Axis is resilient and which second section is orthogonal to the predetermined axis rigid and resilient along the predetermined axis. In addition, the secondary spring comprises at least one horizontal stop which is arranged on the secondary spring in such a way that a force which acts on the horizontal stop orthogonally to the predetermined axis is introduced into the secondary spring between the first and the second section.

Der erste Abschnitt ist entlang der vorgegebenen Achse als steif oder hart zu bezeichnen. Orthogonal zur vorgegebenen Achse ist er federnd oder nachgiebig ausgebildet. Analog ist der zweite Abschnitt orthogonal zur vorgegebenen Achse steif oder hart und entlang der vorgegebenen Achse federnd oder nachgiebig ausgebildet. Steif oder hart bedeutet in diesem Zusammenhang nicht, dass der betreffende Abschnitt der Sekundärfeder zwingend frei von einer Auslenkung in der entsprechenden Richtung ist. Auch in diese Richtung kann der Abschnitt der Sekundärfeder eine gewisse Elastizität aufweisen. Ist ein Abschnitt der Sekundärfeder in einer Richtung jedoch als steif oder hart zu bezeichnen, ist die Federkonstante in dieser Richtung deutlich größer als in einer Richtung, in welcher der Abschnitt der Sekundärfeder federnd oder nachgiebig ausgebildet ist.The first section can be described as stiff or hard along the specified axis. Orthogonally to the specified axis, it is designed to be resilient or flexible. Similarly, the second section is rigid or hard orthogonal to the predetermined axis and resilient or resilient along the predetermined axis. Rigid or hard in this context does not mean that the relevant section of the secondary spring is necessarily free of deflection in the corresponding direction. In this direction too, the section of the secondary spring can have a certain elasticity. However, if a section of the secondary spring is to be described as stiff or hard in one direction, the spring constant in this direction is significantly larger than in a direction in which the section of the secondary spring is designed to be resilient or resilient.

Die vorgegebene Achse verläuft beispielsweise parallel zu einer Längsachse der Sekundärfeder. Insbesondere fällt sie mit der Längsachse der Sekundärfeder zusammen. Die Hauptfederrichtung der Sekundärfeder, also in vorgesehener Betriebslage der Sekundärfeder die Richtung senkrecht zur Erdoberfläche, verläuft weitergebildet ebenfalls parallel zur oder entlang der vorgegebenen Achse. Der Wagenkasten des Schienenfahrzeugs ist dann auf einem Fahrwerk des Schienenfahrzeugs in der Hauptfederrichtung der Sekundärfeder abgefedert, was insbesondere durch den zweiten Abschnitt der Sekundärfeder geleistet wird. Er ist zumindest durch den orthogonal zur Hauptfederrichtung federnden ersten Abschnitt der Sekundärfeder aber auch radial zur Hauptfederrichtung relativ zum Fahrwerk gefedert.The predetermined axis runs, for example, parallel to a longitudinal axis of the secondary spring. In particular, it coincides with the longitudinal axis of the secondary spring. The main spring direction of the secondary spring, that is, in the intended operating position of the secondary spring, the direction perpendicular to the earth's surface, is also developed parallel to or along the predetermined axis. The car body of the rail vehicle is then cushioned on a chassis of the rail vehicle in the main spring direction of the secondary spring, which is achieved in particular by the second section of the secondary spring. It is, however, at least due to the first section of the secondary spring that is resilient orthogonal to the main spring direction also sprung radially to the main spring direction relative to the chassis.

In vorgesehener Betriebslage ist die Sekundärfeder derart zwischen Fahrwerk und Wagenkasten des Schienenfahrzeugs angeordnet, dass die vorgegebene Achse der Sekundärfeder in vertikale Richtung weist und damit parallel zu einer Hochachse des Wagenkastens verläuft und somit der erste Abschnitt der Sekundärfeder vertikal steif und horizontal federnd ausgebildet ist und der zweite Abschnitt horizontal steif und vertikal federnd ausgebildet ist. Eine in horizontaler Richtung auf den Horizontalanschlag einwirkende Kraft, wird zwischen dem ersten und dem zweiten Abschnitt in die Sekundärfeder eingeleitet.In the intended operating position, the secondary spring is arranged between the undercarriage and the body of the rail vehicle in such a way that the predetermined axis of the secondary spring points in the vertical direction and thus runs parallel to a vertical axis of the body and thus the first section of the secondary spring is vertically stiff and horizontally resilient and the second section is horizontally rigid and vertically resilient. A force acting on the horizontal stop in the horizontal direction is introduced into the secondary spring between the first and the second section.

Die Sekundärfeder ist insbesondere entlang der vorgegebenen Achse in einen ersten und zumindest einen weiteren, zweiten Abschnitt geteilt. Gemäß einer Weiterbildung sind der erste und der zweite Abschnitt durch eine Trennplatte voneinander getrennt. Die Trennplatte ist also zwischen dem ersten und dem zweiten Abschnitt der Sekundärfeder angeordnet.The secondary spring is divided in particular along the predetermined axis into a first and at least one further, second section. According to a further development, the first and the second section are separated from one another by a separating plate. The partition plate is thus arranged between the first and the second section of the secondary spring.

Die Trennplatte ist sowohl axial als auch radial zur vorgegebenen Achse steif ausgebildet. Beispielsweise besteht sie aus einem Metall oder einer Metalllegierung. Insbesondere ist sie aus Stahl hergestellt.The partition plate is rigid both axially and radially to the predetermined axis. For example, it consists of a metal or a metal alloy. In particular, it is made of steel.

Die Trennplatte kann auch geeignet ausgebildet sein, Kräfte in Richtung der vorgegebenen Achse der Sekundärfeder auf die Sekundärfeder zu übertragen. So ist es möglich, den zweiten Abschnitt der Sekundärfeder gegen den Wagenkasten des Schienenfahrzeugs mittels eines vorgegebenen Spannwerkzeugs vorzuspannen, mittels welchem eine Kraft aufbringbar ist, welche an der Trennplatte angreift, und welche in einer Richtung zum Wagenkasten hin und damit entgegen der Federkraft des zweiten Abschnitts der Sekundärfeder wirkt.The separating plate can also be designed to transmit forces in the direction of the predetermined axis of the secondary spring to the secondary spring. It is thus possible to pretension the second section of the secondary spring against the car body of the rail vehicle by means of a predetermined tensioning tool, by means of which a force can be applied which acts on the partition plate and which is in a direction towards the car body and thus against the spring force of the second section the secondary spring acts.

Eine Kraft, welche orthogonal zur vorgegebenen Achse auf die Trennplatte einwirkt, wird über die Trennplatte zwischen dem ersten und dem zweiten Abschnitt der Sekundärfeder in die Sekundärfeder eingeleitet. Die Trennplatte ist somit zumindest als Teil des Horizontalanschlags ausgestaltet. Gemäß einer Ausführungsform bildet sie den Horizontalanschlag. Dann kann sie zumindest den ersten Abschnitt in zumindest einer Richtung orthogonal zur vorgegebenen Achse überragen, um in Anschlag an einen komplementär ausgebildeten Horizontalanschlag des Fahrwerks zu kommen.A force which acts on the partition plate orthogonally to the predetermined axis is introduced into the secondary spring between the first and the second section of the secondary spring via the partition plate. The partition plate is thus designed at least as part of the horizontal stop. According to one embodiment, it forms the horizontal stop. Then it can protrude at least the first section in at least one direction orthogonal to the predetermined axis in order to come to a stop against a complementary horizontal stop of the chassis.

Um die horizontalen Bewegungen des Wagenkastens des Schienenfahrzeugs zum Fahrwerk zu begrenzen, ist fahrwerkseitig ein komplementär zum Horizontalanschlag der Sekundärfeder ausgebildeter, fester Horizontalanschlag angeordnet. Dieser umfasst beispielsweise eine feste Anschlagplatte. Diese kann analog zur Trennplatte der Sekundärfeder ähnliche Werkstoffe umfassen, wie auch aus Stahl gefertigt sein. Der Horizontalanschlag des Fahrwerks ist zum Horizontalanschlag der Sekundärfeder ausgerichtet und liegt als Anschlagplatte insbesondere in einer vertikalen Ebene parallel zu einer Längsrichtung des Fahrwerks. Umgangssprachlich bilden zwei komplementär zueinander ausgebildet und ausgerichtete Anschläge einen beidseitigen Anschlag.In order to limit the horizontal movements of the car body of the rail vehicle relative to the chassis, a fixed horizontal stop designed to complement the horizontal stop of the secondary spring is arranged on the chassis side. This includes, for example, a fixed stop plate. Analogously to the separating plate of the secondary spring, this can comprise similar materials, as can also be made of steel. The horizontal stop of the undercarriage is aligned with the horizontal stop of the secondary spring and, as a stop plate, lies in particular in a vertical plane parallel to a longitudinal direction of the undercarriage. Colloquially, two stops designed and complementary to each other form a stop on both sides.

Ein Vorteil einer erfindungsgemäßen Sekundärfeder ist darin begründet, dass der Horizontalanschlag in die Sekundärfeder integriert ist, wodurch keine weiteren Horizontalanschläge am Wagenkasten des Schienenfahrzeugs nötig sind.An advantage of a secondary spring according to the invention is based on the fact that the horizontal stop is integrated in the secondary spring, as a result of which no further horizontal stops on the body of the rail vehicle are necessary.

Gemäß einer weiteren Weiterbildung der Erfindung sind der erste und der zweite Abschnitt koaxial zueinander ausgebildet. Beispielsweise sind der erste und der zweite Abschnitt jeweils rotationssymmetrisch ausgebildet und so zueinander angeordnet, dass sie eine gemeinsame Rotationsachse aufweisen.According to a further development of the invention, the first and the second section are formed coaxially with one another. For example, the first and the second section are each rotationally symmetrical and are arranged relative to one another in such a way that they have a common axis of rotation.

Eine weitere Ausführungsform sieht vor, dass der erste Abschnitt eine entlang der vorgegebenen Achse steife und orthogonal zur vorgegebenen Achse federnde Schichtfeder umfasst und/oder dass der zweite Abschnitt eine orthogonal zur vorgegebenen Achse steife und entlang der vorgegebenen Achse federnde Konusfeder, insbesondere eine Gummi-Metall-Feder, umfasst.A further embodiment provides that the first section comprises a layer spring which is rigid along the predetermined axis and resilient orthogonal to the predetermined axis and / or that the second section comprises a cone spring which is rigid orthogonal to the predetermined axis and resilient along the predetermined axis, in particular a rubber-metal -Feather, includes.

Gemäß einer weiteren Ausgestaltung der erfindungsgemäßen Sekundärfeder ist der erste Abschnitt vorgesehen und geeignet zur Auflagerung auf dem Fahrwerk. Er ist dann entsprechend ausgebildet, insbesondere ist er komplementär zu Mitteln zur Auflagerung der Sekundärfeder auf dem Fahrwerk ausgeformt, um in Auflage auf dem Fahrwerk des Schienenfahrzeugs zu kommen. Analog ist der zweite Abschnitt der Sekundärfeder vorgesehen und entsprechend geeignet ausgebildet zur Auflagerung des Wagenkastens.According to a further embodiment of the secondary spring according to the invention, the first section is provided and suitable for bearing on the chassis. It is then designed accordingly, in particular it is designed to be complementary to means for supporting the secondary spring on the undercarriage in order to come into contact with the undercarriage of the rail vehicle. Analogously, the second section of the secondary spring is provided and is suitably designed for supporting the car body.

Zur Übertragung von Kräften in horizontaler Richtung umfasst das Fahrwerk oder der erste Abschnitt der Sekundärfeder zumindest einen Zapfen. Der jeweils andere Teil umfasst dann eine Vorrichtung zur Aufnahme des Zapfens. Der Zapfen ist insbesondere zentral im ersten Abschnitt der Sekundärfeder angeordnet und steht stirnseitig über den ersten Abschnitt der Sekundärfeder über. Gemäß einem Ausgestaltungsbeispiel verläuft der Zapfen zentral in einer rotationssymmetrischen Schichtfeder. Der Zapfen kann dabei Teil der Sekundärfeder sein oder er ist Teil des Fahrwerks.To transmit forces in the horizontal direction, the undercarriage or the first section of the secondary spring comprises at least one pin. The other part then comprises a device for receiving the pin. The pin is in particular arranged centrally in the first section of the secondary spring and projects beyond the first section of the secondary spring on the end face. According to one embodiment example, the pin runs centrally in a rotationally symmetrical layer spring. The pin can be part of the secondary spring or it is part of the chassis.

Auch der zweite Abschnitt der Sekundärfeder kann zur Übertragung von Kräften in horizontaler Richtung vom Wagenkasten oder auf den Wagenkasten des Schienenfahrzeugs entsprechende Mittel umfassen. Beispielsweise ist er konusförmig als Kegelstumpf ausgebildet, wobei der Wagenkasten dann eine topfförmige Einstülpung zur Aufnahme zumindest eines stirnseitigen Teils des zweiten Abschnitts der Sekundärfeder umfasst. Weitergebildet sind der Wagenkasten und die Sekundärfeder formschlüssig miteinander verbunden, welche formschlüssige Verbindung zumindest parallel zu einer Hochachse des Wagenkastens zum Wagenkasten hin und senkrecht zur Hochachse des Wagenkastens wirkt.The second section of the secondary spring can also include corresponding means for transmitting forces in the horizontal direction from the car body or to the car body of the rail vehicle. For example, it is conical in shape as a truncated cone, the car body then comprising a cup-shaped indentation for receiving at least one end part of the second section of the secondary spring. Developed, the car body and the secondary spring are positively connected to each other, which form-fitting connection acts at least parallel to a vertical axis of the car body towards the car body and perpendicular to the vertical axis of the car body.

Ein erfindungsgemäßes Fahrwerk, insbesondere ein Drehgestell, umfasst zumindest einen zum Horizontalanschlag der Sekundärfeder komplementär ausgebildeten und angeordneten Horizontalanschlag, insbesondere in Form einer Anschlagplatte. Darüber hinaus kann es geeignete Mittel zur Auflagerung zumindest einer erfindungsgemäßen Sekundärfeder auf dem Fahrwerk und Mittel zur Aufnahme von Kräften in horizontaler Richtung aufweisen. Das Fahrwerk ist nach Verwendung als Drehgestell ausgebildet.An undercarriage according to the invention, in particular a bogie, comprises at least one horizontal stop designed and arranged to complement the horizontal stop of the secondary spring, in particular in the form of a stop plate. In addition, it can have suitable means for supporting at least one secondary spring according to the invention on the chassis and means for absorbing forces in the horizontal direction. The chassis is designed as a bogie after use.

Bei dem Schienenfahrzeug handelt es sich insbesondere um ein Niederflurfahrzeug. Es kann mehrere Wagenkästen und mehrere Fahrwerke, beispielsweise Drehgestelle, umfassen. Natürlich sind dann auch mehrere Sekundärfedern zum Abfedern der Wagenkästen auf den Fahrwerken vorgesehen. In einer Weiterbildung ist ein Wagenkasten des Schienenfahrzeugs auf genau einem Fahrwerk abgefedert. Zur Abfederung eines Wagenkastens auf einem Fahrwerk können mehrere Sekundärfedern vorgesehen sein, beispielsweise genau zwei. Ein Fahrwerk kann einen, insbesondere jedoch genau zwei längsliegende Fahrmotoren umfassen.The rail vehicle is in particular a low-floor vehicle. It can comprise several car bodies and several undercarriages, for example bogies. Of course, several secondary springs are then provided for cushioning the car bodies on the undercarriages. In a further development, a car body of the rail vehicle is cushioned on exactly one chassis. To cushion a car body on a chassis, several secondary springs can be provided, for example exactly two. A running gear can comprise one, but in particular exactly two, longitudinal driving motors.

In einer weiteren Weiterbildung der Erfindung ist vorgesehen, dass das Fahrwerk zwei parallel zu einer Längsachse des Fahrwerks angeordnete Fahrmotoren umfasst, wobei zwei Sekundärfedern zur Abfederung des Wagenkastens auf dem Fahrwerk vorgesehen sind, welche zwischen den Fahrmotoren, insbesondere auf einer Linie senkrecht zu einer Längsachse des Fahrwerks, angeordnet sind. Die Verbindungsstellen der Sekundärfedern mit dem Fahrwerk liegen dann auf einer Linie. Weitergebildet teilt diese Line das Fahrwerk in einen vorderen und einen hinteren Teil, welche im Wesentlichen gleich groß sind - sie liegt in einer Quermittenebene.In a further development of the invention it is provided that the undercarriage comprises two traction motors arranged parallel to a longitudinal axis of the undercarriage, two secondary springs for cushioning the car body on the undercarriage being provided, which between the traction motors, in particular on a line perpendicular to a longitudinal axis of the Chassis, are arranged. The connection points of the secondary springs with the chassis are then in line. Developed further, this line divides the undercarriage into a front and a rear part, which are essentially the same size - it lies in a transverse center plane.

Eine weitere Weiterbildung sieht vor, dass das Fahrwerk zumindest einen parallel zur Längsachse des Fahrwerks angeordneten Fahrmotor umfasst, an welchem der zumindest eine komplementär zum Horizontalanschlag der Sekundärfeder ausgebildete Horizontalanschlag angeordnet ist. Der Horizontalanschlag kann dabei unmittelbar am Fahrmotor angeordnet sein; er ist insbesondere integraler Bestandteil des Fahrmotors. In einem weiteren Ausgestaltungsbeispiel umfasst das Fahrwerk, welches insbesondere als Drehgestell ausgebildet ist, zumindest zwei parallel zur Längsachse des Fahrwerks angeordnete Fahrmotoren, zwischen welchen Fahrmotoren zumindest zwei Sekundärfedern so angeordnet sind, insbesondere auf einer Linie senkrecht zur Längsachse des Fahrwerks, dass jede Sekundärfeder benachbart zu jeweils einem Fahrmotor ist, wobei jeder Fahrmotor jeweils zumindest einen zu einem Horizontalanschlag der benachbarten Sekundärfeder komplementär ausgebildeten Horizontalanschlag aufweist. Aber auch Lauffahrwerke können Horizontalanschläge umfassen, welche beispielsweise über Konsolen an den Lauffahrwerken befestigt sind.A further development provides that the undercarriage comprises at least one traction motor arranged parallel to the longitudinal axis of the undercarriage, on which the at least one horizontal stop complementary to the horizontal stop of the secondary spring is arranged. The horizontal stop can be arranged directly on the traction motor; in particular, it is an integral part of the traction motor. In a further embodiment example, the undercarriage, which is designed in particular as a bogie, comprises at least two traction motors arranged parallel to the longitudinal axis of the undercarriage, between which traction motors are arranged at least two secondary springs, in particular on a line perpendicular to the longitudinal axis of the undercarriage so that each secondary spring is adjacent to is in each case a traction motor, each traction motor each having at least one horizontal stop which is complementary to a horizontal stop of the adjacent secondary spring. But running gear can also include horizontal stops, which are attached to the running gear via brackets, for example.

Ein erfindungsgemäßes Schienenfahrzeug umfasst zumindest einen Wagenkasten, mindestens eine erfindungsgemäße Sekundärfeder und wenigstens ein erfindungsgemäßes Fahrwerk, insbesondere ein Drehgestell.A rail vehicle according to the invention comprises at least one car body, at least one secondary spring according to the invention and at least one chassis according to the invention, in particular a bogie.

Der Wagenkasten umfasst geeignete Mittel, um in Auflagerung auf der zumindest einen erfindungsgemäßen Sekundärfeder zu kommen. Des Weiteren kann auch er Mittel zur Aufnahme von Kräften in horizontaler Richtung aufweisen.The car body comprises suitable means for supporting the at least one secondary spring according to the invention. Furthermore, it can also have means for absorbing forces in the horizontal direction.

Kräfte in horizontaler Richtung können auch als Querkräfte bezeichnet werden, wodurch ein Horizontalanschlag auch Queranschlag genannt werden kann.Forces in the horizontal direction can also be referred to as transverse forces, whereby a horizontal stop can also be called a transverse stop.

Die Sekundärfeder ist gemäß einer Ausführungsform so zwischen dem Fahrwerk und dem Wagenkasten des Schienenfahrzeugs angeordnet, dass die vorgegebene Achse der Sekundärfeder im Wesentlichen vertikal ausgerichtet ist. Die Hauptfederrichtung entspricht somit der vertikalen Richtung und verläuft insbesondere parallel zur Längsachse der Sekundärfeder oder fällt mit dieser zusammen. Der erste Abschnitt der Sekundärfeder ist dann vertikal steif und horizontal federnd ausgebildet und der zweite Abschnitt der Sekundärfeder ist somit horizontal steif und vertikal federnd ausgebildet.According to one embodiment, the secondary spring is arranged between the undercarriage and the car body of the rail vehicle in such a way that the predetermined axis of the secondary spring is oriented essentially vertically. The main direction of spring thus corresponds to the vertical direction and in particular runs parallel to the longitudinal axis of the secondary spring or coincides with it. The first section of the secondary spring is then vertically stiff and horizontally resilient and the second section of the secondary spring is thus horizontally stiff and vertically resilient.

Weiterbildungsgemäß ist der erste Abschnitt der Sekundärfeder auf dem Fahrwerk aufgelagert und der Wagenkasten des Schienenfahrzeugs ist auf dem zweiten Abschnitt der Sekundärfeder aufgelagert. Der erste Abschnitt befindet sich somit unterhalb des zweiten Abschnitts.According to a further development, the first section of the secondary spring is supported on the chassis and the car body of the rail vehicle is supported on the second section of the secondary spring. The first section is thus below the second section.

Weitergebildet sind insbesondere zwei Sekundärfedern zur Abfederung des Wagenkastens des Schienenfahrzeugs auf dem Fahrwerk zwischen dem Wagenkasten und dem Fahrwerk angeordnet.In particular, two secondary springs for cushioning the car body of the rail vehicle are arranged on the undercarriage between the car body and the undercarriage.

Die Sekundärfedern, insbesondere ihre Horizontalanschläge, sind so zu den Horizontalanschlägen des Fahrwerks angeordnet, dass diese zumindest paarweise aufeinander einwirken können, um horizontale Bewegungen des Wagenkastens zum Fahrwerk zu begrenzen.The secondary springs, in particular their horizontal stops, are arranged in relation to the horizontal stops of the undercarriage in such a way that they can act on one another at least in pairs in order to limit horizontal movements of the car body relative to the undercarriage.

Horizontale Bewegungen des Fahrwerks relativ zum Wagenkasten und umgekehrt werden mittels der Horizontalanschlagspaarungen von Sekundärfeder und Fahrwerk begrenzt. Um vertikale Bewegungen zu begrenzen können das Fahrwerk und der Wagenkasten jeweils zumindest einen komplementär zueinander ausgebildeten und ausgerichteten Vertikalanschlag aufweisen. Vertikalanschläge können auch Hochanschläge genannt werden.Horizontal movements of the chassis relative to the car body and vice versa are limited by the pair of horizontal stops of the secondary spring and chassis. In order to limit vertical movements, the undercarriage and the car body can each have at least one vertical stop designed to be complementary to one another and aligned. Vertical stops can also be called vertical stops.

Gemäß einer weiteren Weiterbildung ist der zumindest eine Wagenkasten des Schienenfahrzeugs frei von Horizontalanschlägen zum Anschlag an komplementären Horizontalanschlägen des Fahrwerks. Es sind somit keine direkten Horizontalanschläge zwischen dem Wagenkasten und dem Fahrwerk vorgesehen.According to a further development, the at least one car body of the rail vehicle is free of horizontal stops for abutment on complementary horizontal stops of the chassis. There are therefore no direct horizontal stops between the body and the chassis.

Die Erfindung lässt zahlreiche Ausführungsformen zu. Sie wird anhand der nachfolgenden Figuren näher erläutert, in denen jeweils ein Ausgestaltungsbeispiel dargestellt ist. Gleiche Elemente in den Figuren sind mit gleichen Bezugszeichen versehen.

The invention permits numerous embodiments. It is explained in more detail with reference to the following figures, in each of which an embodiment example is shown. Identical elements in the figures are provided with the same reference symbols.
Fig. 1
shows in perspective a bogie of the prior art,
Fig. 2
shows a secondary spring according to the invention on a bogie in partial section.

In Fig. 1 ist ein Drehgestell des Stands der Technik teilweise perspektivisch dargestellt. Auf einer Traverse 6 über einem längsseits angeordneten Fahrmotor 5 sind zwei baugleiche Sekundärfedern 1 zum Abfedern eines nicht veranschaulichten Wagenkastens auf dem Drehgestell angebracht. Insgesamt sind vier Sekundärfedern zwischen dem Drehgestell und dem Wagenkasten angeordnet, wovon nur die Sekundärfedern auf einer Seite des Drehgestells skizziert sind. Sie sind als Uhrglasfedern ausgebildet. Im Längsschnitt weisen sie die Form einer Sanduhr auf, mit einem sich gegenüber zwei sich gegenüberliegenden Stirnseiten verjüngenden Teil. In der Mitte jeder Sekundärfeder 1 ist eine Trennplatte 3 angeordnet.In Fig. 1 a bogie of the prior art is partially shown in perspective. On a traverse 6 above a longitudinally arranged traction motor 5, two identical secondary springs 1 are mounted on the bogie for cushioning an unillustrated car body. A total of four secondary springs are arranged between the bogie and the body, of which only the secondary springs are sketched on one side of the bogie. They are designed as watch glass springs. In longitudinal section they have the shape of an hourglass, with a part tapering towards two opposite end faces. A separating plate 3 is arranged in the middle of each secondary spring 1.

Um Bewegungen des Drehgestells relativ zum Wagenkasten zu begrenzen, weist das Drehgestell sowie der Wagenkasten mehrere Horizontal- und Vertikalanschläge auf. Hier sind jeweils ein Horizontalanschlag 2 und ein Vertikalanschlag 4 des Drehgestells abgebildet. Jeweils ein Horizontalanschlag des Drehgestells und ein komplementär dazu ausgebildeter und angeordneter Horizontalanschlag des Wagenkastens kommen bei einer durch sie begrenzten Relativbewegung des Drehgestells zum Wagenkasten zur Anlage aneinander. Gleiches gilt für die Vertikalanschläge.In order to limit movements of the bogie relative to the car body, the bogie and the car body have several horizontal and vertical stops. A horizontal stop 2 and a vertical stop 4 of the bogie are shown here. In each case one horizontal stop of the bogie and one complementary horizontal stop of the car body come to rest against one another when the relative movement of the bogie to the car body is limited. The same applies to the vertical stops.

Fig. 2 zeigt nun eine erfindungsgemäße Sekundärfeder 1 in montiertem Zustand auf einem Drehgestell 13 im Teilschnitt. Fig. 2 shows a secondary spring 1 according to the invention in the assembled state on a bogie 13 in partial section.

Die Sekundärfeder 1 weist hier einen ersten Abschnitt 8 auf, welcher eine vertikal steife und horizontal federnde Schichtfeder umfasst, und sie weist einen weiteren, zweiten Abschnitt 7 auf, welcher eine horizontal steife und vertikal federnde Konusfeder, hier eine Gummi-Metall-Feder, umfasst.The secondary spring 1 here has a first section 8, which comprises a vertically stiff and horizontally resilient layer spring, and it has a further, second section 7, which comprises a horizontally stiff and vertically resilient cone spring, here a rubber-metal spring ,

Die Sekundärfeder 1 ist hier in einen unteren und oberen Abschnitt geteilt, wobei sie in ihrer vorgesehenen Betriebslage so zwischen dem Drehgestell 13 und dem Wagenkasten 12 des Schienenfahrzeugs angeordnet, dass der erste Abschnitt 8 auf dem Drehgestell 13 montiert ist, wobei der zweite Abschnitt 7 mit dem Wagenkasten 12 des Schienenfahrzeugs verbunden ist. Der erste Abschnitt 8 bildet somit den unteren Abschnitt der Sekundärfeder 1. Der zweite Abschnitt 7 verkörpert den oberen Abschnitt.The secondary spring 1 is divided here into a lower and an upper section, wherein in its intended operating position it is arranged between the bogie 13 and the car body 12 of the rail vehicle in such a way that the first section 8 is mounted on the bogie 13, the second section 7 with the car body 12 of the rail vehicle is connected. The first section 8 thus forms the lower section of the secondary spring 1. The second section 7 embodies the upper section.

Die Abschnitte 7, 8 weisen eine gemeinsame Rotationsachse auf. Diese ist gleichzeitig Längsachse der Sekundärfeder 1. In ihrer Betriebsstellung zeigt diese Achse in vertikale Richtung. Hier verläuft diese Achse entlang eines zentral im ersten Abschnitt 8 der Sekundärfeder 1 angeordneten Zapfens 9.The sections 7, 8 have a common axis of rotation. This is also the longitudinal axis of the secondary spring 1. In its operating position, this axis points in the vertical direction. Here, this axis runs along a pin 9 arranged centrally in the first section 8 of the secondary spring 1.

Um horizontale Bewegungen zwischen dem Drehgestell 13 und dem Wagenkasten 12 zu begrenzen, weisen sowohl das Drehgestell 13 als auch die Sekundärfeder 1 zueinander komplementär ausgebildete und ausgerichtete Horizontalanschläge 2 und 10 auf. Beide Horizontalanschläge 2 und 10 dienen dazu, in aneinander angelegtem Zustand, Kräfte in horizontaler Richtung des jeweils anderen Horizontalanschlags aufzunehmen. Der Wagenkasten 12 ist hingegen frei von Horizontalanschlägen.In order to limit horizontal movements between the bogie 13 and the car body 12, both the bogie 13 and the secondary spring 1 have horizontal stops 2 and 10 which are designed and aligned to be complementary to one another. Both horizontal stops 2 and 10 serve to absorb forces in the horizontal direction of the respective other horizontal stop in the state in which they are placed against one another. The car body 12, however, is free of horizontal stops.

Der Horizontalanschlag 2 der Sekundärfeder 1 umfasst hier eine Trennplatte 3 zwischen dem ersten und dem zweiten Abschnitt 8 und 7 der Sekundärfeder 1. Drehgestellseitig ist hier an einem längsseits angeordneten Fahrmotor 5 ein fester Horizontalanschlag 10 in Form einer Anschlagplatte für die Trennplatte 3 der Sekundärfeder 1 vorgesehen.The horizontal stop 2 of the secondary spring 1 here comprises a separating plate 3 between the first and second sections 8 and 7 of the secondary spring 1. A fixed horizontal stop 10 in the form of a stop plate for the separating plate 3 of the secondary spring 1 is provided here on a traction motor 5 arranged on the longitudinal side ,

Der Horizontalanschlag in Form der Trennplatte 3 der Sekundärfeder 1 ist dabei so an der Sekundärfeder 1 angeordnet und mit ihr verbunden ist, dass eine in horizontaler Richtung auf den Horizontalanschlag 2 einwirkende Kraft, zwischen dem ersten und dem zweiten Abschnitt 8 und 7 in die Sekundärfeder 1 einleitbar ist.The horizontal stop in the form of the separating plate 3 of the secondary spring 1 is arranged on the secondary spring 1 and connected to it in such a way that a force acting in the horizontal direction on the horizontal stop 2 occurs between the first and second sections 8 and 7 in the secondary spring 1 can be initiated.

Über den zentral in der Schichtfeder angeordneten Zapfen 9 werden Querkräfte, also Kräfte in horizontaler Richtung, vom Drehgestell 13 auf die Sekundärfeder 1 oder von der Sekundärfeder 1 auf das Drehgestell 13 übertragen. Dazu weist das Drehgestell 13 eine entsprechend komplementär ausgeformte Aufnahme für den Zapfen 9 auf. Analog werden Querkräfte vom Wagenkasten 12 auf die Sekundärfeder 1 oder von der Sekundärfeder 1 auf den Wagenkasten 12 mittels einer geeigneten Schnittstelle übertragen. Hier weist der zweite Abschnitt 7 der Sekundärfeder 1 die Form eines Kegelstumpfes auf, welcher in einer topfförmigen Einbuchtung 11 des Wagenkastens 12 aufgenommen ist. Die mit der Sekundärfeder koaxiale topfförmige Einbuchtung 11 des Wagenkastens 12 und der zweite Abschnitt 7 der Sekundärfeder 1 bilden insbesondere eine Passung.Shear forces, that is to say forces in the horizontal direction, are transmitted from the bogie 13 to the secondary spring 1 or from the secondary spring 1 to the bogie 13 via the pin 9 arranged centrally in the layer spring. For this purpose, the bogie 13 has a correspondingly complementarily shaped receptacle for the pin 9. Analogously, transverse forces are transmitted from the body 12 to the secondary spring 1 or from the secondary spring 1 to the body 12 by means of a suitable interface. Here, the second section 7 of the secondary spring 1 has the shape of a truncated cone, which is received in a cup-shaped indentation 11 of the car body 12. The cup-shaped indentation 11 of the car body 12 coaxial with the secondary spring and the second section 7 of the secondary spring 1 in particular form a fit.

Dadurch sind der Wagenkasten und die Sekundärfeder formschlüssig miteinander verbunden, welche formschlüssige Verbindung zumindest parallel zu einer Hochachse des Wagenkastens zum Wagenkasten hin und senkrecht zur Hochachse des Wagenkastens wirkt.As a result, the body and the secondary spring are positively connected to one another, which positive connection acts at least parallel to a vertical axis of the body towards the body and perpendicular to the vertical axis of the body.

Um vertikale Bewegungen zu begrenzen weist der Wagenkasten 12 einen Vertikalanschlag 14 aufweisen. Dieser kann in Anlage an das Drehgestell 13 kommen.In order to limit vertical movements, the car body 12 has a vertical stop 14. This can come into contact with the bogie 13.
