Description

Die Erfindung bezieht sich auf ein Fahrwerk eines Schienenfahrzeuges mit radial einstellbaren Radsätzen gemäß dem Oberbergriff des Anspruchs 1. Das vorgeschlagene Fahrwerk ist insbesondere bei Güterwagendrehgestellen einsetzbar.The invention relates to a chassis of a rail vehicle with radial adjustable wheelsets according to the Oberbergriff of claim 1. The proposed chassis is particularly applicable to freight wagon bogies.

Konventionelle Güterwagendrehgestelle haben vielfach den Nachteil einer in Fahrtrichtung gesehen längsstreifen Radsatzführung, die nicht gleisschonend und nicht leise ist. Das für Güterwagen weiterhin bekannte Schakendrehgestell hat zwar längselastische, radial einstellbare Radsätze, wobei jedoch der Nachteil auftritt, dass infolge der Reibung im Schakengestänge Quietschgeräusche entstehen. Durch das Anschneiden des Spurkranzes and der Schiene entstehen laute, quietschende und kreischende Geräusche. Gleichzeitig erfolgt trotz der bewirkten radialen Einstellung ein relativ hoher Verschleiß zwischen Rad und Schiene. Zudem ist das Schakendrehgestell infolge der aufwendigen Federung relative kostenträchtig.Conventional freight wagon bogies often have the disadvantage of a Direction of travel Seen longitudinal stripes Wheelset guidance, which is not track friendly and not quiet. The still known for freight wagons bogie bogie has indeed longitudinally elastic, radially adjustable wheelsets, but the disadvantage occurs that as a result of friction in the hook linkage, squeaking noises occur. By the Cutting the wheel flange and the rail creates loud, squeaky and screeching noises. At the same time despite the effected radial adjustment a relatively high wear between wheel and rail. Moreover, that is Shaft bogie due to the complex suspension relatively expensive.

Aus der US-A-3517620 ist ein Fahrwerk bekannt mit einem zwischen Reibkeilen geführten Achslagergehäuse, wobei zur radialen Einstellung der Radsätze die Reibkeile sich gegenüber dem Fahrwerkrahmen verschieben müssen.From US-A-3517620 a landing gear is known with one between friction wedges guided axle bearing housing, wherein for the radial adjustment of the wheelsets the Friction wedges must move relative to the chassis frame.

Der Erfindung liegt die Aufgabe zugrunde, ein insbesondere für Güterwagendrehgestelle einsetzbares, verbessertes Fahrwerk mit radial einstellbaren Radsätzen anzugeben.The invention is based on the object, in particular for Freight wagons usable, improved chassis with radial to specify adjustable wheelsets.

Diese Aufgabe wird in Verbindung mit den Merkmalen des Oberbegriffes erfindungsgemäß durch die im Anspruch 1 gekennzeichneten Merkmale gelöst.This task is combined with the characteristics of the generic term solved according to the invention by the features characterized in claim 1.

Die mit der Erfindung erzielbaren Vorteile bestehen insbesondere darin, daß das vorgeschlagene Fahrwerk eines Schienenfahrzeuges mti radial einstellbaren Radsätzen ein relativ geringes Gewicht aufweist, einen gleisschonenden und leisen Betrieb ermöglicht und zudem realtiv kostengünstig produzierbar ist. Das geringe Gewicht wird insbesondere durch die kompakte, funktionsintegrierte Bauweise erreicht. Der leise Betrieb wird durch die bewirkte quasi optimale Radialstellung erreicht. Darüber hinaus werden durch die kompakte Bauweise die schallreflektierenden Flächen sowie die zur Schwingung anregenden Flächen minimiert.The achievable with the present invention consist in particular that the proposed chassis of a rail vehicle mti radially adjustable Has a relatively low weight wheelsets, a track-saving and quiet Operation is possible and also realtiv producible economically. The small one Weight is particularly due to the compact, functionally integrated design reached. The quiet operation is caused by the quasi-optimal radial position reached. In addition, the compact design of the sound reflecting surfaces as well as the vibrating surfaces minimized.

In Fig. 1 ist eine Seitenansicht eines Abschnitts des vorgeschlagenen Fahrwerks eines Schienenfahrzeuges mit radial einstellbaren Radsätzen dargestellt. Es ist ein Laufrad 1 eines Fahrwerks eines Schienenfahrzeuges zu erkennen, dessen Achse 2 in bekannter Weise beidseitig mittels in Achslagergehäusen 3 integrierten Achslagern gelagert ist. Die Schiene ist mit Ziffer 4 bezeichnet.In Fig. 1 is a side view of a portion of the proposed suspension a rail vehicle with radially adjustable wheelsets shown. It is a Impeller 1 to recognize a chassis of a rail vehicle, the axis of the second in a known manner on both sides by means integrated in Achslagergehäusen 3 Axle bearings is stored. The rail is designated by numeral 4.

Die Primärfederung eines Laufrades 1 erfolgt mittels zweier beidseitig des Achslagergehäuses 3 angeordneter Spiralfedern 5, 6. Die untere Abstützung der Spiralfedern 5, 6 erfolgt über eine beidseitig des Achslagergehäuses 3 kragende Aufnahme 7. Die oberen Enden der Spiralfedern 5 bzw. 6 greifen in Reibkeile 8 bzw. 9 ein bzw. drücken gegen diese Reibkeile, deren geneigte Oberseiten von schiefen Ebenen 10 bzw. 11 einer Aufnahme 12 des Fahrwerkrahmens bzw. Drehgestellrahmens abgestützt werden. Die zum Achslagergehäuse 3 gerichteten Seitenflächen der Reibkeile 8 bzw. 9 sind mit Reibplatten 13 bzw. 14 versehen.The primary suspension of an impeller 1 by means of two sides of the Axle bearing housing 3 arranged coil springs 5, 6. The lower support of Spiral springs 5, 6 via a cantilevered on both sides of the axle housing 3 Recording 7. The upper ends of the coil springs 5 and 6 engage in friction wedges 8 and 9 on or press against these friction wedges whose inclined tops of oblique Levels 10 and 11 of a receptacle 12 of the chassis frame or Bogie frame are supported. The directed to the axle box 3 Side surfaces of the friction wedges 8 and 9 are provided with friction plates 13 and 14, respectively.

Gemäß Fig. 2 ist ein Schnitt durch diese Primärfederung dargestellt. Es ist die den Reibkeil 9 umfassende Aufnahme 12 des Fahrwerkrahmens bzw. Drehgestellrahmens des Schienenfahrzeuges sowie die zwischen Aufnahme 7 des Achslagergehäuses und Aufnahme 12 eingespannte Spiralfeder 6 zu erkennen.2, a section through this primary suspension is shown. It's the one Reibkeil 9 comprehensive recording 12 of the chassis frame or Bogie frame of the rail vehicle and between recording 7 of the Achslagergehäuses and recording 12 clamped coil spring 6 can be seen.

In Fig. 3 ist ein Schnitt eines Radsatzes des Schienenfahrzeuges dargestellt. Es ist das Laufrad 1 mit Achse 2, Achslager 15, Achslagergehäuse 3, Aufnahme 7 des Achslagergehäuses und Aufnahme 12 des Fahrwerkrahmens bzw. Drehgestellrahmens zu erkennen. Die seitliche Bewegungsmöglichkeit zwischen Radsatz und Rahmen des Drehgestells wird durch einen Anschlag 16 des Fahrwerkrahmens bzw. Drehgestellrahmens zum Achslagergehäuse begrenzt.In Fig. 3 is a section of a wheel of the rail vehicle is shown. It is the impeller 1 with axis 2, axle bearings 15, axle bearing housing 3, 7 receiving the Axle bearing housing and receptacle 12 of the chassis frame or Detect bogie frame. The lateral movement possibility between Wheel and frame of the bogie is characterized by a stop 16 of the Chassis frame or bogie frame limited to the axle box.

In Fig. 4 ist eine Draufsicht auf einen Abschnitt eines Radsatzes des Schienenfahrzeuges dargestellt. Es sind das Rad 1 mit Achse 2, Achslager 15 mit Achslagergehäuse 3, die beiden Spiralfedern 5, 6, die Aufnahme 7 des Achslagergehäuses und die beiden Reibplatten 13, 14 zu erkennen.In Fig. 4 is a plan view of a portion of a wheel of the Railway vehicle shown. There are the wheel 1 with axis 2, axle bearing 15 with Axle bearing housing 3, the two coil springs 5, 6, the receptacle 7 of the Achslagergehäuses and the two friction plates 13, 14 can be seen.

In Fig. 5 ist eine Seitenansicht eines Drehgestells 17 mit zwei Radsätzen des Schienenfahrzeuges dargestellt. Der Drehgestellrahmen ist vorteilhaft als verwindungsweicher H-Rahmen ohne Kopfträger ausgeführt. Konventionelle Lösungen haben im Unterschied hierzu einen Kopfträger. Das Drehgestell 17 weist zwei Radsätze 18, 19 auf, wobei zur Lagerung der Achsen nicht die geschlossenen Achslagergehäuse gemäß den Figuren 1 bis 4, sondern Wechsellagergehäuse 20, 21 dienen.In Fig. 5 is a side view of a bogie 17 with two sets of wheels Railway vehicle shown. The bogie frame is advantageous as torsionally soft H-frame without head support. conventional In contrast, solutions have a head carrier. The bogie 17 has two wheelsets 18, 19, wherein for the storage of the axes not the closed Axle bearing housing according to Figures 1 to 4, but change bearing housing 20, 21 serve.

Zur unteren Abstützung der Primärfederung weist jedes Wechsellagergehäuse 20, 21 zwei getrennte Aufnahmen 22, 23 für die Spiralfedern auf. In einfacher Weise demontierbare untere Lagerschalen 24 bilden den unteren Gehäuseabschnitt eines Wechsellagergehäuses bzw. Achslagergehäuses. Diese alternative Lösung mit nach unten offenem Wechsellagergehäuse 20, 21 ermöglicht vorteilhaft einen einfachen, schnellen und kostengünstigen Radsatztausch ohne Ausbau von Achslagergehäusen und der Federung. Am rechten Radsatz des Drehgestells nach Fig. 5 ist die untere Lagerschale dranmontiert. Selbstverständlich ist das in Fig. 5 gezeigte Ausführungsbeispiel auch mit um das Achslager geschlossenen Achslagergehäusen ausführbar (wie bezüglich den Fig. 1 bis 4 beschrieben).For the lower support of the primary suspension, each removable bearing housing 20, 21 two separate receptacles 22, 23 for the coil springs on. In a simple way removable lower bearing shells 24 form the lower housing portion of a Replacement bearing housing or axle bearing housing. This alternative solution with after bottom open removable bearing housing 20, 21 advantageously allows a simple, fast and cost-effective exchange of wheels without removal of Axlebox housings and the suspension. On the right wheel of the bogie after 5, the lower bearing shell is mounted on it. Of course, this is in FIG. 5 embodiment shown also closed to the axle box Achslagergehäusen executable (as described with reference to FIGS. 1 to 4).

Wie bereits aus den vorstehenden Erläuterungen hervorgeht, besteht die Primärfederung des Fahrwerkes des Schienenfahrzeuges aus den beidseitig vom Achslager 15 bzw. Achslagergehäuse 3, 20, 21 angeordneten Spiralfedern 5, 6, welche wahlweise aus einer einteiligen oder einer zweiteiligen Feder bestehen. Bei Einsatz einer einteiligen Feder weisen die Spiralfedern vorzugsweise eine progressive Federkennlinie auf (TKS-Feder). Bei Einsatz einer zweiteiligen Feder weist jede Spiralfeder eine Innen- und eine Außenfeder auf, die vorzugsweise konzentrisch zueinander vorgesehen sind.As already explained in the previous explanatory notes, the Primary suspension of the chassis of the rail vehicle from both sides of the Axle bearing 15 and axle bearing housing 3, 20, 21 arranged coil springs 5, 6, which optionally consist of a one-piece or a two-part spring. at Use of a one-piece spring, the coil springs preferably have a progressive spring characteristic on (TKS spring). When using a two-piece spring For example, each coil spring has an inner spring and an outer spring which are preferably are provided concentrically with each other.

Auf der oberen Federseite lagern die Reibkeile 8, 9, welche über die schiefen Ebenen 10, 11 der Aufnahme 12 und die Vertikalkraft beidseitig an die Achslagergehäuse 3, 20, 21 gedrückt werden. So entsteht die für die vertikale Reibdämpfung notwendige Andruckkraft am Achslager 15. Die Reibungsdämpfung ergibt sich aus der Andruckkraft, welche abhängig von der Federbelastung und dem Reibkoeffizient zwischen der Reibplatte 13, 14 und dem Achslagergehäuse 3, 20, 21 ist. Damit wird die Reibungsdämpfung entsprechend der Zuladung des Schienenfahrzeuges im gewünschten Maße proportional erhöht.On the upper spring side store the friction wedges 8, 9, which over the oblique Planes 10, 11 of the receptacle 12 and the vertical force on both sides of the Axle bearing housing 3, 20, 21 are pressed. This creates the vertical Friction damping necessary pressure force at the axle bearing 15. Friction damping results from the pressure force, which depends on the spring load and the Friction coefficient between the friction plate 13, 14 and the axle box 3, 20, 21st is. Thus, the friction damping according to the load of the Rail vehicle proportionally increased to the desired extent.

Die handelsüblichen Reibpaarungen Reibplatte 13, 14 / Achslagergehäuse 3, 20, 21 werden derart gewählt, daß bei den auftretenden Bewegungen keine Geräusche entstehen.The commercial friction pairings friction plate 13, 14 / axle bearing housing 3, 20, 21st are chosen so that no noise in the movements occurring arise.

Die Querfederung erfolgt über die Flexicoilwirkung der Spiralfedern 5, 6. Die Bewegung in Querrichtung, also quer zur Fahrtrichtung, erfolgt zwischen Achslagergehäuse 3, 20, 21 und den in der Aufnahme 12 befindlichen Reibkeilen 8, 9. Die Reibkeile 8, 9 sind wiederum gegenüber dem Fahrwerkrahmen bzw. Drehgestellrahmen des Schienenfahrzeuges in Querrichtung geführt. Nach Erreichen der maximal zulässigen Querbewegung erfolgt der Anschlag zwischen Drehgestellrahmen und Achslagergehäuse 3, 20, 21. Die Querbewegung wird ebenfalls - wie die vertikale Bewegung - über die vertikale Reibplatte 13, 14 des Reibkeils 8, 9 zum Achslagergehäuse 3, 20, 21 gedämpft. Auch hier erfolgt im vorgegeben und gewünschten Maße die Reibdämpfung abhängig von der Zuladung.The transverse suspension is via the Flexicoilwirkung the coil springs 5, 6. Die Movement in the transverse direction, ie transverse to the direction of travel, takes place between Axle bearing housing 3, 20, 21 and located in the receptacle 12 friction wedges 8, 9. The friction wedges 8, 9 are in turn relative to the chassis frame or Bogie frame of the rail vehicle in the transverse direction. To If the maximum permissible transverse movement is reached, the stop takes place between Bogie frame and axle box 3, 20, 21. The transverse movement is also - as the vertical movement - on the vertical friction plate 13, 14 of the Reibkeils 8, 9 to the axle box 3, 20, 21 damped. Again, takes place in the given and desired dimensions, the friction damping depending on the payload.

Die Anforderungen an die radiale Einstellbarkeit werden über die geometrischen Verhältnisse zwischen Radsatzmitte, Federfußpunkthöhe und Anlagehöhe des Reibkeils 8, 9 in Verbindung mit der Bewegungsmöglichkeit des Reibkeils 8, 9 in Längsrichtung realisiert. Durch das konische Radprofil werden Wendekräfte erzeugt, die im Radberührpunkt wirken und als Tx-Kräfte bezeichnet werden. Diese Tx-Kräfte wirken an einem Radsatz 18, 19 entgegengesetzt und versuchen, den Radsatz radial einzustellen.The requirements for the radial adjustability are over the geometric Relationship between wheel center, spring base height and system height of the Reibkeils 8, 9 in conjunction with the possibility of movement of the friction wedge 8, 9 in Realized longitudinal direction. By the conical wheel profile turning forces are generated, which act in Radberührpunkt and are referred to as Tx forces. These Tx forces act on a wheelset 18, 19 opposite and try the wheelset adjust radially.

Die radiale Einstellbarkeit des Radsatzes 18, 19 erfolgt in zwei Stufen. In der ersten Stufe, bei der die Tx-Kräfte kleiner als die auftretende Reibkraft sind, erfolgt eine Wendebewegung infolge des Abstandes zwischen Achslagermitte und Reibkeilhöhe. Infolge des durch den Abstand erzeugten Momentes um die Querachse erfolgt eine Pendelbewegung des Achslagergehäuses 3, 20, 21 um den Abstützpunkt des Reibkeils 8, 9 zum Achslagergehäuse 3, 20, 21. Durch diese Pendelbewegung, die oberhalb der Achsmitte des Radsatzes 18, 19 erfolgt, wird eine Längsbewegung in der Ebene der Radsatzdrehmitte bewirkt. Damit können in der ersten Stufe kleine Lenkbewegungen des Radsatzes 18, 19 realisiert werden.The radial adjustability of the wheelset 18, 19 takes place in two stages. In the first Stage, in which the Tx forces are smaller than the friction force occurring, takes a Turning movement due to the distance between the middle bearing center and friction wedge height. As a result of the moment generated by the distance about the transverse axis is a Oscillation of the axle bearing housing 3, 20, 21 to the support point of the Reibkeils 8, 9 to the axle bearing housing 3, 20, 21. By this pendulum motion, the takes place above the center of the wheel set 18, 19, a longitudinal movement in the plane of Radsatzdrehmitte causes. This can be small in the first stage Steering movements of the wheelset 18, 19 can be realized.

In der zweiten Stufe, bei welcher die Tx-Kräfte größer als die auftretende Reibkraft sind, erfolgt eine Verschiebung der Reibkeile 8, 9 gegenüber dem Fahrwerkrahmen bzw. Drehgestellrahmen des Schienenfahrzeuges und damit eine größere Lenkbewegung des Radsatzes 18, 19. Infolge der nun bewirkten radialen Einstellung des Radsatzes 18, 19 sinken die Tx-Kräfte und die Lenkbewegung geht in den Mechanismus der ersten Stufe zurück, in dem nur kleine Korrekturen der Lenkbewegung bewirkt werden. Durch die über die zweite Stufe erfolgte Bewegung ergibt sich ein quasi kraftfreier neuer Gleichgewichtszustand im Bogen. Dies ist die Voraussetzung für den gewünschten niedrigen Verschleiß durch die radiale Einstellung der Räder des Schienenfahrzeuges. In the second stage, where the Tx forces are greater than the friction force occurring are, there is a displacement of the friction wedges 8, 9 relative to the chassis frame or bogie frame of the rail vehicle and thus a larger Steering movement of the wheelset 18, 19. Due to the now effected radial adjustment of the wheelset 18, 19, the Tx forces fall and the steering movement goes into the Mechanism of the first stage back, in which only small corrections of the Steering movement can be effected. Through the movement over the second stage results in a quasi-force-free new equilibrium state in the arc. this is the Prerequisite for the desired low wear by the radial Adjustment of the wheels of the rail vehicle.

Gegenüber konventionellen, radial einstellbaren Radsätzen bei Schienenfahrzeugen, bei denen die Tx-Kräfte während der ganzen Bogenfahrt permanent gegen den Widerstand der Primärfedersteifigkeit (cx-Steifigkeit) arbeiten, erfolgt bei der erfindungsgemäßen konstruktiven Lösung vorteilhaft ein quasi kraftfreier, neuer Gleichgewichtszustand.Compared to conventional, radially adjustable wheelsets for rail vehicles, in which the Tx forces during the entire Bogenfahrt permanently against the Resistance of the primary spring stiffness (cx-rigidity) work, takes place at the inventive design solution advantageously a quasi force-free, new Equilibrium.

Die komplette Bauweise der erfindungsgemäßen Vorrichtung ergibt sich aus der Anordnung von jeweils nur einer Spiralfedereinheit neben den Achsen bzw. Achslagern pro Laufrad. Hierdurch erhält man in vorteilhafter Weise einen realtiv kurzen Hebelarm der Federkräfte an ihren oberen und unteren Auflagern bezüglich der Achse 2 und insbesondere der Lagerung des Drehgestellrahmens am Wagenkasten. The complete construction of the device according to the invention results from the Arrangement of only one coil spring unit next to the axes or Axle bearings per impeller. This advantageously gives a realtiv short lever arm of the spring forces on their upper and lower supports relative the axis 2 and in particular the storage of the bogie frame on Car body.
