Definitions
- the invention relates to a wheel guide for bogies of rail vehicles, in particular vehicles of local transport with primary springs between the wheel bearings and long beams of the bogie frame, and secondary springs between the long beams of the bogie frame and the car body, in which the wheels are located horizontally and transversely to the direction of travel by guide frames Axis of rotation are pivotally connected to a cross member of a bogie frame, at least two wheels of the bogie being designed as idler wheels and rigidly connected to the guide frame with pillow blocks, the guide frame being connected to two bearings and being connected to the cross member and the guide frame being stiff in the direction of travel, is elastically displaceable laterally between stops and is elastically supported in the event of a lateral stop with respect to the movements of the legs.
- DE-OS 38 08 593 shows a bogie with bogie frame and wheel guides, two wheels each forming a pair of wheels and connected via a guide frame by bearings to a cross member of the bogie frame.
- This version is suitable for local rail vehicles.
- the object of the invention is therefore to provide wheel guides for bogies that allow automatic radial adjustment using the dynamic driving forces and the track geometry and thus reduce the wear on the rails and wheel flange and at the same time increase the safety against derailment.
- the guide bearings according to the invention consist of a cylindrical metal mandrel, to which an elastomer layer is applied and which is pressed into a bearing eye of the intermediate carrier, surrounded by a metal sleeve.
- the metal mandrel has laterally reduced bearing journals, which lie in the bearing blocks of the guide frame.
- the centering bearings consist of downward spikes of the cross member, which are edged with a metal sleeve and an elastomer cylinder and are mounted in the bearing eyes of the intermediate carrier.
- the centering bearings are set softer than the guide bearings.
- the guide frame pivots around a center of rotation between the centering bearings. Due to the elastic connection between the guide frame and the intermediate carrier on the one hand and the intermediate carrier and cross member on the other hand, an oppositely superimposed movement occurs, whereby an automatic radial adjustment of the wheel pairs is achieved.
- the bogie according to FIG. 1 has a bogie frame 1 with secondary springs 12 and a cross member 4.
- the cross member 4 has in the middle a projection 24 projecting in the direction of the associated wheel pair 3.
- a plate-shaped intermediate support 8 is arranged below the projection 24, the projection 24 of the cross member 4 and the intermediate support 8 being arranged by two, one behind the other in the longitudinal direction of the bogie Centering bearings 9, 10 are interconnected.
- a cross strut 25 of a guide frame 2 on which the wheels 26 of the pair of wheels 3 are suspended via pillow blocks 5.
- Two guide bearings 7 are arranged between the cross strut 25 and the intermediate carrier 8.
- the cross strut 25 has an obtuse angle open in the direction of the wheel pair 3, the guide bearings 7 being connected to one leg each, thereby causing an inclination of the transverse axis of the guide bearings 7 to the longitudinal axis of the bogie between 10 and 40 °.
- the intermediate carrier 8 is connected in the opposite direction to the wheel pair 3 by dampers 11 with the bogie frame 1, whereby abrupt movements such as shocks are damped.
- FIG 2 the arrangement of the intermediate carrier 8 between the cross member 4 of the bogie frame and the cross strut 25 of the guide frame can be seen.
- the cross member 4 and the intermediate member 8 are connected to one another by centering bearings 9, 10.
- the centering bearing 10 shown here consists of a downwardly directed metal mandrel 22 of the cross member 4, which comprises a metal sleeve 21 and an elastomer cylinder 20 and is fixedly mounted in a bearing eye 19 of the intermediate carrier 8.
- the elastomer cylinder 20 allows the intermediate carrier 8 cardanic movements around the metal mandrel 22.
- the metal sleeve 21 is fastened to the metal mandrel 22 with a fastening nut 23.
- the guide bearings 7 are arranged between the intermediate carrier 8 and the cross strut 25 of the guide frame. These each consist of a metal mandrel 13, which is surrounded by an elastomer layer 15 and bordered by a metal sleeve 16 and is mounted in a bearing eye 17 of the intermediate carrier 8.
- the metal mandrel 13 has laterally bearing pins 14 with a reduced diameter compared to the metal mandrel 13, the bearing blocks 17 are mounted. There is an elastic play between the metal sleeve 16 and the bearing blocks 17 available, the bearing blocks 17 of the metal sleeve 16 serve as a stop.
- the bearing blocks have incisions 28 for the bearing pins 14, which receive them in a form-fitting manner such that rotational movements of the metal mandrel 13 cannot occur, e.g. by means of bearing pins 14 formed as a hexagon in correspondingly conical notches 28.
- the driving forces acting on the pair of wheels and thus on the guide frame are converted into lateral and, when stopped, swiveling movements of the metal sleeves 16 in the guide bearings 7, the movements being simultaneously transmitted to the centering bearings 9, 10 via the intermediate carrier 8.
- the centering bearings 9, 10 have a pivot point between them, around which the intermediate carrier 8 rotates and the formation of the centering bearings 9, 10 simultaneously enables gimbal movements. This arrangement enables an automatic radial adjustment of the wheel pair, which reduces wear on the wheel flange and increases safety against derailment.

Description
Die Erfindung betrifft eine Radführung für Drehgestelle von Schienenfahrzeugen, insbesondere von Fahrzeugen des Nahverkehrs mit Primärfedern zwischen den Radlagern und Langträgern des Drehgestellrahmens, sowie Sekundärfedern zwischen den Langträgern des Drehgestellrahmens und dem Wagenkasten, bei denen die Räder durch Führungsrahmen über eine horizontal und quer zur Fahrtrichtung liegende Drehachse schwenkbar mit einem Querträger eines Drehgestellrahmens verbunden sind, wobei mindestens zwei Räder des Drehgestells als Losräder ausgeführt und mit Stehlagern mit dem Führungsrahmen starr verbunden sind, wobei der Führungsrahmen an zwei Lagerungen angeschlossen und mit dem Querträger verbunden ist und wobei der Führungsrahmen in Fahrtrichtung steif, lateral zwischen Anschlägen elastisch verschiebbar und bei seitlichem Anschlag gegenüber Schenkbewegungen elastisch gelagert ist.The invention relates to a wheel guide for bogies of rail vehicles, in particular vehicles of local transport with primary springs between the wheel bearings and long beams of the bogie frame, and secondary springs between the long beams of the bogie frame and the car body, in which the wheels are located horizontally and transversely to the direction of travel by guide frames Axis of rotation are pivotally connected to a cross member of a bogie frame, at least two wheels of the bogie being designed as idler wheels and rigidly connected to the guide frame with pillow blocks, the guide frame being connected to two bearings and being connected to the cross member and the guide frame being stiff in the direction of travel, is elastically displaceable laterally between stops and is elastically supported in the event of a lateral stop with respect to the movements of the legs.
Derartige Lagerungen für Drehgestelle sind bekannt. Die DE-OS 38 08 593 zeigt ein Drehgestell mit Drehgestellrahmen und Radführungen, wobei jeweils zwei Räder einen Radpaar bilden und über einen Führungsrahmen durch Lagerungen an einem Querträger des Drehgestellrahmens angeschlossen sind.Such bearings for bogies are known. DE-OS 38 08 593 shows a bogie with bogie frame and wheel guides, two wheels each forming a pair of wheels and connected via a guide frame by bearings to a cross member of the bogie frame.
Diese Ausführung ist geeignet für Schienenfahrzeuge des Nahverkehrs. Als nachteilig hat sich jedoch erwiesen, daß beim Einlauf in enge Gleisbögen der Elastizität der Führungslager nicht ausreicht, den duch Querschlupf verursachten Schienen- und Spurkranzverschleiß wirksam zu vermindern und daß dennoch bei der Geradeausfahrt wirkende asymmetrische Kräfte ohne Beeinträchtigung der Laufstabilität ausgeglichen werden können.This version is suitable for local rail vehicles. However, it has proven to be disadvantageous that, when entering narrow track bends, the elasticity of the guide bearings is not sufficient to effectively wear out the rail and flange wear caused by transverse slip reduce and that asymmetrical forces acting when driving straight ahead can be compensated without impairing the running stability.
Aufgabe der Erfindung ist es daher, Radführungen für Drehgestelle zu schaffen, die unter Ausnutzung der fahrdynamischen Kräfte und der Gleisgeometrie eine selbsttätige Radialeinstellung erlauben und so den Schienen- und Spurkranzverschleiß verringern und wodurch gleichzeitig die Entgleisungssicherheit erhöht wird.The object of the invention is therefore to provide wheel guides for bogies that allow automatic radial adjustment using the dynamic driving forces and the track geometry and thus reduce the wear on the rails and wheel flange and at the same time increase the safety against derailment.
Diese Aufgabe wird mit den im kennzeichnenden Teil des Hauptanspruchs genannten Merkmalen gelöst. Weitere Ausführungen und Weiterbildungen der Erfindung sind in den Unteransprüchen umfaßt.This object is achieved with the features mentioned in the characterizing part of the main claim. Further embodiments and developments of the invention are included in the subclaims.
Überraschend hat sich insbesondere gezeigt, daß die Anordnung eines Zwischenträgers zwischen mindestens einem Querträger des Drehgestellrahmens und mindestens einem Führungsrahmen, wobei die Führungslager Führungsrahmen und Zwischenträger verbinden und der Zwischenträger über zwei elastische Zentrierlager an dem Querträger aufgehängt ist, eine Schwenkbewegung des Radpaares mit dem Führungsrahmen von ca. 1,5° bis 3° gewährleistet. Dies wird insbesondere dann erreicht, wenn die Führungslager zur Längsachse des Drehgestells geneigt sind und der Neigungswinkel zwischen der Querachse jeweils eines Führungslagers und der Längsachse des Drehgestells zwischen 10° und 40° beträgt.Surprisingly, it has been shown in particular that the arrangement of an intermediate support between at least one cross member of the bogie frame and at least one guide frame, the guide bearings connecting the guide frame and intermediate support and the intermediate support being suspended from the cross member via two elastic centering bearings, results in a pivoting movement of the wheel pair with the guide frame from approx. 1.5 ° to 3 ° guaranteed. This is achieved in particular when the guide bearings are inclined to the longitudinal axis of the bogie and the angle of inclination between the transverse axis of a guide bearing and the longitudinal axis of the bogie is between 10 ° and 40 °.
Die erfindungsgemäßen Führungslager bestehen aus einem zylindrischen Metalldorn, auf den eine Elastomerschicht aufgebracht ist und der mit einer Metallhülse umgeben in ein Lagerauge des Zwischenträgers eingepreßt ist. Der Metalldorn hat seitlich im Durchschnitt verminderte Lagerzapfen, die in Lagerböcken des Führungsrahmens liegen.The guide bearings according to the invention consist of a cylindrical metal mandrel, to which an elastomer layer is applied and which is pressed into a bearing eye of the intermediate carrier, surrounded by a metal sleeve. The metal mandrel has laterally reduced bearing journals, which lie in the bearing blocks of the guide frame.
Bei auf das Radpaar einwirkenden, eine Schwenkbewegung hervorrufenden Kräften erfolgt zunächst eine laterale Verschiebung des Führungsrahmens, wobei diese Bewegung begrenzt wird durch das elastische Spiel, das die Metallhülsen zwischen Lagerböcken des Führungsrahmens haben. Kommen die Metallhülsen seitlich zum Anschlag, so bewirkt die um den zentralen Metalldorn liegende Elastomerschicht ein elastisches Nachgeben, wodurch eine Schwenkbewegung des Führungsrahmens möglich wird.In the case of forces acting on the pair of wheels and causing a pivoting movement, there is first a lateral displacement of the guide frame, this movement being limited by the elastic play that the metal sleeves have between the bearing blocks of the guide frame. If the metal sleeves come to a side stop, the elastomer layer around the central metal mandrel causes an elastic yield, which enables the guide frame to pivot.
Bei der Ausführung der Erfindung mit zusätzlich zwischen Querträger und Führungsrahmen angeordnetem Zwischenträger wirken die Kräfte auch auf die Zentrierlager zwischen dem Zwischenträger und dem Querträger des Drehgestellrahmens.In the embodiment of the invention with an additional intermediate carrier arranged between the cross member and the guide frame, the forces also act on the centering bearings between the intermediate carrier and the cross member of the bogie frame.
Die Zentrierlager bestehen aus nach unten gerichteten Dornen des Querträgers, die mit einer Metallhülse und mit einem Elastomerzylinder eingefaßt und in Lageraugen des Zwischenträgers gelagert sind. Die Zentrierlager sind weicher eingestellt, als die Führungslager.The centering bearings consist of downward spikes of the cross member, which are edged with a metal sleeve and an elastomer cylinder and are mounted in the bearing eyes of the intermediate carrier. The centering bearings are set softer than the guide bearings.
Die Schwenkbewegungen des Führungsrahmens erfolgen um einen Drehpunkt in der Mitte zwischen den Zentrierlagern. Es kommt durch die jeweils elastische Verbindung zwischen Führungsrahmen und Zwischenträger einerseits und Zwischenträger und Querträger andererseits zu einer gegensinnig überlagerten Bewegung, wodurch eine selbsttätige Radialeinstellung der Radpaare ereicht wird.The guide frame pivots around a center of rotation between the centering bearings. Due to the elastic connection between the guide frame and the intermediate carrier on the one hand and the intermediate carrier and cross member on the other hand, an oppositely superimposed movement occurs, whereby an automatic radial adjustment of the wheel pairs is achieved.
Die optimale Einstellung wird dabei durch das Zusammenwirken der verschiedenen Faktoren erreicht:
- der Härte von Elastomerschicht und Elastomerzylinder, sowie deren Abstimmung aufeinander, wobei Härten von jeweils Shore 50 - 80° A und Shore 40 - 70° A verwendet werden können;
- des Neigungswinkels a zwischen der Querachse einer Führungsbuchse und der Längsachse des Drehgestellrahmens, wobei der Neigungswinkel zwischen 10° und 40° liegen soll;
- des Abstands der Führungslager voneinander, wobei dieser Abstand zwischen 300 und 800mm betragen kann,
- und des Abstands der Zentrierlager voneinander, wobei dieser Abstand zwischen 100 und 250mm betragen kann.
- the hardness of the elastomer layer and the elastomer cylinder, and their coordination with one another, whereby hardnesses of Shore 50-80 ° A and Shore 40-70 ° A can be used;
- of the angle of inclination a between the transverse axis of a guide bush and the longitudinal axis of the bogie frame, the angle of inclination between Should be 10 ° and 40 °;
- the distance of the guide bearings from each other, which distance can be between 300 and 800 mm,
- and the distance between the centering bearings, which distance can be between 100 and 250mm.
Diese Parameter sind derart aufeinander abzustimmen, daß eine Schwenkbewegung von Führungsrahmen mit Radpaar von zwischen 1,5° und 3° ermöglicht wird.These parameters are to be coordinated with one another in such a way that a pivoting movement of the guide frame with a wheel pair of between 1.5 ° and 3 ° is made possible.

Das Drehgestell gemäß Figur 1 weist in dem dargestellten Ausschnitt einen Drehgestellrahmen 1 mit Sekundärfedern 12 und einem Querträger 4 auf. Der Querträger 4 hat in der Mitte einen in Richtung des zugehörigen Radpaares 3 ragenden Vorsprung 24. Unterhalb des Vorsprungs 24 ist ein plattenförmiger Zwischenträger 8 angeordnet, wobei der Vorsprung 24 des Querträgers 4 und der Zwischenträger 8 durch zwei, in der Längsrichtung des Drehgestells hintereinander angeordnete Zentrierlager 9, 10 miteinander verbunden sind. Wiederum unterhalb des Zwischenträgers 8 verläuft eine Querstrebe 25 eines Führungsrahmens 2, an dem über Stehlager 5 die Räder 26 des Radpaares 3 aufgehängt sind. Zwischen der Querstrebe 25 und dem Zwischenträger 8 sind zwei Führungslager 7 angeordnet. Die Querstrebe 25 weist einen in Richtung des Radpaares 3 offenen stumpfen Winkel auf, wobei die Führungslager 7 mit je einem Schenkel verbunden sind, wodurch sich eine Neigung der Querachse der Führungslager 7 zur Längsachse des Drehgestells von zwischen 10 und 40° ergibt.In the detail shown, the bogie according to FIG. 1 has a bogie frame 1 with

In Figur 2 ist die Anordnung des Zwischenträgers 8 zwischen dem Querträger 4 des Drehgestellrahmens und der Querstrebe 25 des Führungsrahmens zu erkennen. Der Querträger 4 und der Zwischenträger 8 sind durch Zentrierlager 9, 10 miteinander verbunden. Das hier gezeigte Zentrierlager 10 besteht aus einem nach unten gerichteten Metalldorn 22 des Querträgers 4, der mit einer Metallhülse 21 und einem Elastomerzylinder 20 umfaßt und fest in einem Lagerauge 19 des Zwischenträgers 8 gelagert ist. Der Elastomerzylinder 20 erlaubt dem Zwischenträger 8 kardanische Bewegungen um den Metalldorn 22. Die Metallhülse 21 ist mit einer Befestigungsmutter 23 auf dem Metalldorn 22 befestigt.In Figure 2, the arrangement of the
Zwischen dem Zwischenträger 8 und der Querstrebe 25 des Führungsrahmens sind die Führungslager 7 angeordnet. Diese bestehen aus jeweils einem Metalldorn 13, der mit einer Elastomerschicht 15 umgeben und mit einer Metallhülse 16 eingefasst ist und in einem Lagerauge 17 des Zwischenträgers 8 gelagert ist. Der Metalldorn 13 weist seitlich Lagerzapfen 14 mit gegenüber dem Metalldorn 13 verringertem Durchmesser auf, die Lagerböcken 17 gelagert sind. Zwischen der Metallhülse 16 und den Lagerböcken 17 ist ein elastisches Spiel vorhanden, wobei die Lagerböcke 17 der Metallhülse 16 als Anschlag dienen.The
Die Lagerböcke weisen Einschnitte 28 für die Lagerzapfen 14 auf, die diese formschlüssig derart aufnehmen, daß Drehbewegungen des Metalldorns 13 nicht auftreten können, z.B. durch als Sechskant ausgebildete Lagerzapfen 14 in entsprechend konischen Einschnitten 28.The bearing blocks have

Die auf das Radpaar und damit auf den Führungsrahmen wirkenden Fahrkräfte setzen sich in laterale und, bei Anschlag, Schwenkbewegungen der Metallhülsen 16 in den Führungslagern 7 um, wobei die Bewegungen gleichzeitig über den Zwischenträger 8 auf die Zentrierlager 9, 10 übertragen werden. Die Zentrierlager 9, 10 weisen einen zwischen ihnen liegenden Drehpunkt auf, um den eine Drehbewegung des Zwischenträgers 8 erfolgt und wobei die Ausbildung der Zentrierlager 9, 10 gleichzeitig kardanische Bewegungen ermöglicht. Durch diese Anordnung wird eine selbsttätige Radialeinstellung des Radpaares ermöglicht, wodurch der Spurkranzverschleiß verringert und die Entgleisungssicherheit erhöht wird.The driving forces acting on the pair of wheels and thus on the guide frame are converted into lateral and, when stopped, swiveling movements of the
