Description

Beschreibung description
Sekundärfeder mit integriertem Queranschlag Secondary spring with integrated transverse stop
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 Secondary springs, for example, designed as Uhrglasfedern are arranged between a chassis and a car body of a rail vehicle to cushion the car body on the chassis. They serve the transmission of
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. Traction, vertical and lateral forces between chassis and car body. They are usually bolted to the car body and the chassis. In order to limit the movements between the car body and the chassis, additional complementary mechanical end stops are provided in the form of vertical and horizontal stops on the car body and on the chassis. These are also called cross and high stops. Thus, collisions and thus damage to suspension components or components of the car body are avoided.
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 suspension components or components of the car body in a simple and cost-effective 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 claim 1. Further developments and refinements of the invention can be found in the features of the dependent claims again.
Eine erfindungsgemäße Sekundärfeder zur Abfederung eines Wa¬ genkastens 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 vorgegebe- nen Achse federnd ausgebildet ist und welcher zweite Ab¬ schnitt orthogonal zur vorgegebenen Achse steif und entlang der vorgegebenen Achse federnd ausgebildet ist. Darüber hin¬ aus umfasst die Sekundärfeder zumindest einen Horizontalan- schlag, 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. 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 diesemA secondary spring of the invention to mitigate one Wa ¬ genkastens of a rail vehicle on a chassis of the rail vehicle, in particular on a bogie of the rail vehicle, comprising a first and at least one further, second portion, said first portion along a predetermined axis stiff and orthogonal to the predefined NEN axis is resilient and which second Ab ¬ 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. The first section can be described as stiff or hard along the given axis. Orthogonal to the given axis, it is resilient or yielding. Analogously, the second section is orthogonal to the predetermined axis stiff or hard and formed along the predetermined axis resilient or yielding. Stiff or hard means in this
Zusammenhang nicht, dass der betreffende Abschnitt der Sekun¬ därfeder 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. That the portion of the seconding ¬ därfeder in question is not necessarily free connection of a deflection in the corresponding direction. Also in this direction, the portion of the secondary spring may have a certain elasticity. However, if a portion of the secondary spring is rigid or hard in one direction, the spring constant in that direction is significantly greater than in a direction in which the portion of the secondary spring is resilient.
Die vorgegebene Achse verläuft beispielsweise parallel zu ei¬ ner 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 insbe- sondere durch den zweiten Abschnitt der Sekundärfeder geleistet wird. Er ist zumindest durch den orthogonal zur Hauptfe¬ derrichtung federnden ersten Abschnitt der Sekundärfeder aber auch radial zur Hauptfederrichtung relativ zum Fahrwerk gefedert . The predetermined axis runs, for example, parallel to egg ¬ ner 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, ie in the intended operating position of the secondary spring, the direction perpendicular to the earth's surface, further developed also runs 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 made in particular by the second portion of the secondary spring. It is, however, at least by the orthogonal to Hauptfe ¬ derrichtung resilient first portion of the secondary spring 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 ange¬ ordnet, dass die vorgegebene Achse der Sekundärfeder in ver¬ tikale Richtung weist und damit parallel zu einer Hochachse des Wagenkastens verläuft und somit der erste Abschnitt der Sekundärfeder vertikal steif und horizontal federnd ausgebil- det ist und der zweite Abschnitt horizontal steif und verti¬ kal 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 such ¬ between chassis and car body of the rail vehicle ¬ assigns that the predetermined axis of the secondary spring in ver ¬ tical direction and thus runs parallel to a vertical axis of the car body and thus the first portion of the secondary spring vertically stiff and horizontally resilient is formed and the second portion is horizontally rigid and verti ¬ cal resilient. A force acting in a horizontal direction on the horizontal stop force is introduced between the first and the second section in the secondary spring.
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 one embodiment, the first and the second section are separated by a partition plate. The partition plate is thus arranged between the first and the second portion of the secondary spring.
Die Trennplatte ist sowohl axial als auch radial zur vorgege¬ benen Achse steif ausgebildet. Beispielsweise besteht sie aus einem Metall oder einer Metalllegierung. Insbesondere ist sie aus Stahl hergestellt. The partition plate is both axially and radially stiff to specified differently surrounded 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 vorzu¬ spannen, 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. 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 Rich¬ tung orthogonal zur vorgegebenen Achse überragen, um in Anschlag an einen komplementär ausgebildeten Horizontalanschlag des Fahrwerks zu kommen. The partition plate may also be designed to transmit forces in the direction of the predetermined axis of the secondary spring to the secondary spring. Thus, it is possible vorzu ¬ span the second portion of the secondary spring against the car body of the rail vehicle by means of a predetermined clamping tool, by means of which a force can be applied, which acts on the partition plate, and which in a direction towards the car body and thus against the spring force of second section of the secondary spring acts. A force which acts orthogonally to the predetermined axis on the partition plate is introduced via the partition plate between the first and the second portion of the secondary spring in the secondary spring. The partition plate is thus configured at least as part of the horizontal stop. According to one embodiment, it forms the horizontal stop. Then, it may at least protrude beyond the first portion in at least one direction Rich ¬ orthogonal to the predetermined axis to come into abutment against a complementary formed 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 ausge- bildeter, fester Horizontalanschlag angeordnet. Dieser um- fasst beispielsweise eine feste Anschlagplatte. Diese kann analog zur Trennplatte der Sekundärfeder ähnliche Werkstoffe umfassen, wie auch aus Stahl gefertigt sein. Der Horizontal¬ anschlag des Fahrwerks ist zum Horizontalanschlag der Sekun- därfeder ausgerichtet und liegt als Anschlagplatte insbeson¬ dere 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 to the chassis, a solid horizontal stop formed complementarily to the horizontal stop of the secondary spring is arranged on the chassis side. This includes, for example, a fixed stop plate. This can analogously to the partition plate of the secondary spring include similar materials, as well as be made of steel. The horizontal ¬ stroke of the suspension is därfeder aligned to the horizontal stop of the secondary and is a stop plate insbeson ¬ particular in a vertical plane parallel to a longitudinal direction of the chassis. Colloquially form two complementary trained and aligned attacks a two-sided attack.
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 due to the fact that the horizontal stop is integrated into the secondary spring, whereby no further horizontal stops on the car body of the rail vehicle are necessary.
Gemäß einer weiteren Weiterbildung der Erfindung sind der erste und der zweite Abschnitt koaxial zueinander ausgebil¬ det. Beispielsweise sind der erste und der zweite Abschnitt jeweils rotationssymmetrisch ausgebildet und so zueinander angeordnet, dass sie eine gemeinsame Rotationsachse aufwei¬ sen . Eine weitere Ausführungsform sieht vor, dass der erste Ab¬ schnitt eine entlang der vorgegebenen Achse steife und ortho¬ gonal zur vorgegebenen Achse federnde Schichtfeder umfasst und/oder dass der zweite Abschnitt eine orthogonal zur vorge- gebenen Achse steife und entlang der vorgegebenen Achse federnde Konusfeder, insbesondere eine Gummi-Metall-Feder, umfasst . According to a further development of the invention, the first and the second portion coaxially ausgebil ¬ det. For example, the first and second portions are respectively formed rotationally symmetric to one another and so arranged that they aufwei ¬ sen a common axis of rotation. A further embodiment provides that the first Ab ¬ cut a rigid along the predetermined axis and ortho ¬ gonal to said given axis resilient layer spring comprises and / or that the second portion rigid orthogonally to said given axis and resilient along the predetermined axis conical spring , in particular a rubber-metal spring comprises.
Gemäß einer weiteren Ausgestaltung der erfindungsgemäßen Se- kundärfeder 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 Wa¬ genkastens . 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. He is then trained accordingly, in particular it is complementary to means for bearing the secondary spring formed on the chassis to come in contact with the chassis of the rail vehicle. Analogously, the second portion of the secondary spring is provided and designed suitably suitable for bearing the Wa ¬ genkast.
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. 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 Kegel¬ stumpf ausgebildet, wobei der Wagenkasten dann eine topfför- mige Einstülpung zur Aufnahme zumindest eines stirnseitigen Teils des zweiten Abschnitts der Sekundärfeder umfasst. Wei¬ tergebildet sind der Wagenkasten und die Sekundärfeder formschlüssig miteinander verbunden, welche formschlüssige Ver- bindung zumindest parallel zu einer Hochachse des Wagenkas¬ tens zum Wagenkasten hin und senkrecht zur Hochachse des Wa¬ genkastens wirkt.

Darüber hinaus kann es geeignete Mittel zur Auflagerung zumindest ei- ner erfindungsgemäßen Sekundärfeder auf dem Fahrwerk und Mittel zur Aufnahme von Kräften in horizontaler Richtung aufweisen. Das Fahrwerk ist nach Verwendung als Drehgestell ausge¬ bildet . 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. For transmission of forces in the horizontal direction, the chassis or the first portion 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. According to one embodiment, the pin extends centrally in a rotationally symmetrical layer spring. The pin can be part of the secondary spring or it is part of the chassis. Also, the second portion of the secondary spring may comprise 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 cone-shaped as a cone ¬ blunt, wherein the car body then comprises a cup-shaped indentation for receiving at least one front-side part of the second portion of the secondary spring. Wei ¬ tergebildet are the car body and the secondary spring connected positively to one another, which form-fitting encryption Binding acts at least parallel to a vertical axis of the Wagenkas ¬ least to the car body and perpendicular to the vertical axis of the Wa ¬ genkast.

In addition, it can have suitable means for bearing at least one inventive secondary spring on the chassis and means for absorbing forces in the horizontal direction. The chassis is designed after use as a bogie ¬ forms. The rail vehicle is in particular a low-floor vehicle. It may include a plurality of car bodies and a plurality of bogies, such as bogies. Of course, then several secondary springs are provided for cushioning the car bodies on the chassis. In one development, a car body of the rail vehicle is cushioned on exactly one chassis. To cushion a car body on a chassis, a plurality of secondary springs may be provided, for example, exactly two. A chassis may include one, but in particular exactly two longitudinal traction motors.
In einer weiteren Weiterbildung der Erfindung ist vorgesehen, dass das Fahrwerk zwei parallel zu einer Längsachse des Fahr¬ werks angeordnete Fahrmotoren umfasst, wobei zwei Sekundärfe¬ dern zur Abfederung des Wagenkastens auf dem Fahrwerk vorge- sehen sind, welche zwischen den Fahrmotoren, insbesondere auf einer Linie senkrecht zu einer Längsachse des Fahrwerks, an¬ geordnet 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. Eine weitere Weiterbildung sieht vor, dass das Fahrwerk zu¬ mindest einen parallel zur Längsachse des Fahrwerks angeord¬ neten Fahrmotor umfasst, an welchem der zumindest eine komplementär zum Horizontalanschlag der Sekundärfeder ausgebil- dete Horizontalanschlag angeordnet ist. Der Horizontalan¬ schlag 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, zumin- dest 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 Sekundärfe¬ der 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 Ho¬ rizontalanschläge umfassen, welche beispielsweise über Konso¬ len an den Lauffahrwerken befestigt sind. In a further development of the invention it is provided that the chassis comprises two spaced parallel to a longitudinal axis of the driving ¬ factory traction motors, wherein two Sekundärfe ¬ countries are provided to cushion the coach body on the running gear disposed between the drive motors, and in particular a Line perpendicular to a longitudinal axis of the chassis, are arranged on ¬ . The junctions of the secondary springs with the chassis then lie on a line. Developed this line divides the chassis in a front and a rear part, which are essentially the same size - it lies in a transverse center plane. A further development provides that the chassis comprises at least a ¬ parallel to the longitudinal axis of the chassis angeord ¬ Neten traction motor, on which is arranged at least one complementary trained to the horizontal stop of the secondary spring end to horizontal stop. The Horizontalan ¬ impact can be arranged directly on the traction motor; in particular, it is an integral part of the drive motor. In a further exemplary embodiment, the chassis, which is designed in particular as a bogie, at least two parallel to the longitudinal axis of the chassis arranged traction motors, between which traction motors at least two secondary springs are arranged, in particular on a line perpendicular to the longitudinal axis of the chassis, that each secondary ¬ which is adjacent to each drive motor, each drive motor has at least one complementary to a horizontal stop of the adjacent secondary spring horizontal stop. But running trolleys can include Ho ¬ rizontalanschläge which are attached, for example, about Konso ¬ len on the running chassis.
Ein erfindungsgemäßes Schienenfahrzeug umfasst zumindest ei¬ nen Wagenkasten, mindestens eine erfindungsgemäße Sekundärfe¬ der und wenigstens ein erfindungsgemäßes Fahrwerk, insbeson¬ dere ein Drehgestell. An inventive rail vehicle comprises at least egg ¬ NEN car body, at least one invention Sekundärfe ¬ and the at least one inventive suspension, insbeson ¬ 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 coming into contact with 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 Quer¬ anschlag genannt werden kann. Die Sekundärfeder ist gemäß einer Ausführungsform so zwischen dem Fahrwerk und dem Wagenkasten des Schienenfahrzeugs ange¬ ordnet, dass die vorgegebene Achse der Sekundärfeder im We¬ sentlichen vertikal ausgerichtet ist. Die Hauptfederrichtung entspricht somit der vertikalen Richtung und verläuft insbe¬ sondere 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 horizon¬ tal steif und vertikal federnd ausgebildet. Forces in the horizontal direction can also be referred to as the transverse forces, whereby a horizontal stop and transverse stop ¬ may be mentioned. The secondary spring is arranged according to an embodiment ¬ so between the chassis and the car body of the rail vehicle, that the predetermined axis of the secondary spring to We ¬ sentlichen is oriented vertically. The main spring direction thus corresponds to the vertical direction and extends in particular ¬ parallel to the longitudinal axis of the secondary spring or coincides with this. The first portion of the secondary spring is then vertically stiff and horizontally resilient and the second portion of the secondary spring is thus horizon ¬ tal stiff and vertically resilient.
Weiterbildungsgemäß ist der erste Abschnitt der Sekundärfeder auf dem Fahrwerk aufgelagert und der Wagenkasten des Schie- nenfahrzeugs ist auf dem zweiten Abschnitt der Sekundärfeder aufgelagert. Der erste Abschnitt befindet sich somit unter¬ halb des zweiten Abschnitts. According to the invention, 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. Thus, the first portion is located at ¬ half of the second section.
Weitergebildet sind insbesondere zwei Sekundärfedern zur Ab- federung des Wagenkastens des Schienenfahrzeugs auf dem Fahr¬ werk zwischen dem Wagenkasten und dem Fahrwerk angeordnet. Two secondary springs for exhaust of the car body of the rail vehicle are further formed, in particular suspension arranged on the driving ¬ factory between the superstructure 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 to the horizontal stops of the chassis that they can act on each other at least in pairs to limit horizontal movements of the car body to the chassis.
Horizontale Bewegungen des Fahrwerks relativ zum Wagenkasten und umgekehrt werden mittels der Horizontalanschlagspaarungen von Sekundärfeder und Fahrwerk begrenzt. Um vertikale Bewe¬ gungen zu begrenzen können das Fahrwerk und der Wagenkasten jeweils zumindest einen komplementär zueinander ausgebildeten und ausgerichteten Vertikalanschlag aufweisen. Vertikalan- schläge können auch Hochanschläge genannt werden. Horizontal movements of the chassis relative to the car body and vice versa are limited by means of the horizontal stop pairings of secondary spring and chassis. Can to limit vertical BEWE ¬ conditions the chassis and the car body each have at least one mutually complementary formed and aligned in vertical abutment. Vertical stops can also be called high stops.
Gemäß einer weiteren Weiterbildung ist der zumindest eine Wagenkasten des Schienenfahrzeugs frei von Horizontalanschlägen zum Anschlag an komplementären Horizontalanschlägen des Fahr- werks. Es sind somit keine direkten Horizontalanschläge zwi¬ schen dem Wagenkasten und dem Fahrwerk vorgesehen. 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 ver- sehen. According to a further development of the at least one car body of the rail vehicle is free of horizontal stops to stop at complementary horizontal stops of the chassis. There are thus no direct horizontal stops between ¬ rule the car body and the chassis provided. The invention allows numerous embodiments. It will be explained in more detail with reference to the following figures, in each of which a design example is shown. Identical elements in the figures are provided with the same reference numerals.

Technik,  Technology,
Fig. 2 zeigt eine erfindungsgemäße Sekundärfeder auf einem  Fig. 2 shows a secondary spring according to the invention on a
Drehgestell im Teilschnitt.  Bogie in partial section.
In Fig. 1 ist ein Drehgestell des Stands der Technik teilwei¬ se perspektivisch dargestellt. Auf einer Traverse 6 über ei¬ nem 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 Uhrglas- federn 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. 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 Drehge¬ stells abgebildet. Jeweils ein Horizontalanschlag des Drehge- stells und ein komplementär dazu ausgebildeter und angeordne¬ ter Horizontalanschlag des Wagenkastens kommen bei einer durch sie begrenzten Relativbewegung des Drehgestells zum Wagenkasten zur Anlage aneinander. Gleiches gilt für die Verti¬ kalanschläge . In Fig. 1, a bogie of the prior art teilwei ¬ se is shown in perspective. On a cross member 6 via ei ¬ nem arranged side drive motor 5 two identical secondary springs 1 are mounted on the bogie for cushioning a not illustrated car body. A total of four secondary springs between the bogie and the car body are arranged, of which only the secondary springs are outlined 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 tapered opposite two opposite end faces part. In the middle of each secondary spring 1, a partition plate 3 is arranged. To limit movement of the bogie relative to the car body, the bogie and the car body on several horizontal and vertical stops. Here are each a horizontal stop 2 and a vertical stop 4 of the Drehge ¬ stells shown. In each case a horizontal stop of the bogie and a complementary trained and arranged ¬ ter horizontal stop of the car body come in a limited by them relative movement of the bogie to the car body to the plant to each other. The same applies to the Verti ¬ kalanschläge.
Fig. 2 zeigt nun eine erfindungsgemäße Sekundärfeder 1 in montiertem Zustand auf einem Drehgestell 13 im Teilschnitt. Die Sekundärfeder 1 weist hier einen ersten Abschnitt 8 auf, welcher eine vertikal steife und horizontal federnde Schicht¬ feder umfasst, und sie weist einen weiteren, zweiten Abschnitt 7 auf, welcher eine horizontal steife und vertikal federnde Konusfeder, hier eine Gummi-Metall-Feder, umfasst. Fig. 2 shows a secondary spring 1 according to the invention in the assembled state on a bogie 13 in partial section. The secondary spring 1 here has a first portion 8, which comprises a vertically rigid and horizontally resilient layer ¬ spring, and it has a further, second portion 7, which is a horizontally rigid and vertically resilient cone spring, here a rubber-metal spring , includes.
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 here divided into a lower and upper portion, being arranged in its intended operating position between the bogie 13 and the car body 12 of the rail vehicle, that the first portion 8 is mounted on the bogie 13, wherein the second portion 7 with is connected to the car body 12 of the rail vehicle. The first portion 8 thus forms the lower portion of the secondary spring 1. The second portion 7 embodies the upper portion.
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 simultaneously 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 which is 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 je- weils anderen Horizontalanschlags aufzunehmen. Der Wagenkas¬ ten 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 mutually complementary and aligned horizontal stops 2 and 10. Both horizontal stops 2 and 10 serve, in an attached state, to absorb forces in the horizontal direction of the respective other horizontal stop. The Wagenkas ¬ th 12 is, however, free of horizontal stops.
Der Horizontalanschlag 2 der Sekundärfeder 1 umfasst hier ei¬ ne Trennplatte 3 zwischen dem ersten und dem zweiten Ab- schnitt 8 und 7 der Sekundärfeder 1. Drehgestellseitig ist hier an einem längsseits angeordneten Fahrmotor 6 ein fester Horizontalanschlag 10 in Form einer Anschlagplatte für die Trennplatte 3 der Sekundärfeder 1 vorgesehen. Der Horizontalanschlag in Form der Trennplatte 3 der Sekun¬ därfeder 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 ers¬ ten und dem zweiten Abschnitt 8 und 7 in die Sekundärfeder 1 einleitbar ist. The horizontal stop 2 of the secondary spring 1 comprises here ei ¬ ne partition plate 3 between the first and the second section 8 and 7 of the secondary spring 1. bogie side is here on a longitudinally arranged drive motor 6, a solid horizontal stop 10 in the form of a stop plate for the partition plate. 3 provided the secondary spring 1. The horizontal stop in the form of the separating plate 3 of the seconds ¬ därfeder 1 is arranged on the secondary spring 1 and is connected to it, that in the horizontal direction acting on the horizontal stop 2 force, between the ers ¬ th and the second section 8 and 7 in the secondary spring 1 can be introduced.
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 About the centrally arranged in the laminated spring pin 9 transverse forces, ie forces in the horizontal direction, from the bogie 13 to the secondary spring 1 or transmitted from the secondary spring 1 to the bogie 13. For this purpose, the bogie 13 has a correspondingly complementarily shaped receptacle for the pin 9. Analog transverse forces are from the car body 12 to the secondary spring 1 or from the secondary spring 1 to the car body 12 by means of a suitable
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 auf- genommen ist. Die mit der Sekundärfeder koaxiale topfförmige Einbuchtung 11 des Wagenkastens 12 und der zweite Abschnitt 7 der Sekundärfeder 1 bilden insbesondere eine Passung. Transfer interface. Here, the second section 7 of the secondary spring 1 has the shape of a truncated cone, which is accommodated in a cup-shaped indentation 11 of the car body 12. The coaxial with the secondary spring cup-shaped recess 11 of the car body 12 and the second portion 7 of the secondary spring 1 in particular form a fit.
Dadurch sind der Wagenkasten und die Sekundärfeder form- schlüssig miteinander verbunden, welche formschlüssige Ver¬ bindung zumindest parallel zu einer Hochachse des Wagenkas¬ tens zum Wagenkasten hin und senkrecht zur Hochachse des Wa¬ genkastens wirkt. Um vertikale Bewegungen zu begrenzen weist der Wagenkasten 12 einen Vertikalanschlag 14 aufweisen. Dieser kann in Anlage an das Drehgestell 13 kommen. As a result, the car body and the secondary spring are positively connected with each other, which positively Ver ¬ bond acts at least parallel to a vertical axis of the Wagenkas ¬ least to the car body and perpendicular to the vertical axis of Wa ¬ genkast. In order to limit vertical movements, the car body 12 has a vertical stop 14. This can come into contact with the bogie 13.
