Description

Die Erfindung betrifft eine Befestigung für einen Radsatzienker eines Schienenfahrzeugs, insbesondere zur Befestigung des Radsatzlenkers an einem Radsatzlagergehäuse oder einem Rahmen des Drehgestells des Schienenfahrzeugs.The invention relates to a fastening for a Radsatzienker a rail vehicle, in particular for attachment of the Radsatzlenkers to a Radsatzlagergehäuse or a frame of the bogie of the rail vehicle.

Radsätze von Schienenfahrzeugen sind üblicherweise mittels Radsatzfedern, welche im Wesentlichen senkrecht ausgerichtet sind, mit einem Fahrzeugrahmen beziehungsweise einem Drehgestellrahmen des Schienenwagens verbunden. Die wesentliche Feder- und Stabilisierungsrichtung dieser Radsatzfedern ist die Vertikale, so dass üblicherweise zur Aufnahme von Längs- und Querkräften Radsatzlenker vorgesehen sind, welche eine Verbindung zwischen dem Lagergehäuse für die Radsätze zum einen und dem Fahrzeugrahmen, beziehungsweise dem Drehgestellrahmen, zum anderen herstellen. Hierbei dienen die Radsatzlenker zur Führung des Radsatzes in Gleisrichtung und damit zum Übertragen von Treib- und Bremskräften in Längsrichtung des Schienenfahrzeugs. Zusätzlich müssen Radsatzlenker auch Querkräfte aufnehmen. Hierzu wurde in der DE 39 35 319 A1 eine Schräganordnung der Radsatzlenker zur Längsachse des Drehgestellrahmens vorgeschlagen. Eine alternative Ausgestaltung ist aus der DE 27 35 574 A1 bekannt, in der eine Ausführung eines Radsatzlenkers mit drei Gelenkpunkten beschrieben wird, wobei dem Drehgestellrahmen zwei Gelenkpunkte zugeordnet sind, von denen einer eine weichere Dämpfung aufweist.Wheel sets of rail vehicles are usually connected by means of Radsatzfedern, which are oriented substantially vertically, with a vehicle frame or a bogie frame of the rail car. The essential spring and stabilizing direction of this Radsatzfedern is the vertical, so usually provided for receiving longitudinal and transverse forces Radsatzlenker which connect to the other between the bearing housing for the wheel sets on the one hand and the vehicle frame, or the bogie frame. Here, the Radsatzlenker serve to guide the wheelset in the track direction and thus for transmitting driving and braking forces in the longitudinal direction of the rail vehicle. In addition, wheelset must also absorb lateral forces. This was done in the DE 39 35 319 A1 proposed an oblique arrangement of the Radsatzlenker to the longitudinal axis of the bogie frame. An alternative embodiment is from the DE 27 35 574 A1 in which an embodiment of a wheel set with three articulation points is described, wherein the bogie frame two hinge points are assigned, one of which has a softer damping.

Die vom Radsatzlenker erzeugte Querstabilisierung des Radsatzes dient unterschiedlichen Zwecken. Zum einen ist der Radsatz beim Geradeausfahren in axialer Richtung zu stabilisieren, was insbesondere bei Schnellfahrten und bei schadhaften Gleiskörpern wesentlich ist. Durch die vom Radsatzlenker aufgebrachten Querkräfte können Vibrationen am Radsatz unterdrückt werden und sowohl der Komfort wie auch die Fahrsicherheit des Schienenfahrzeugs verbessert werden. Darüber hinaus dienen die aus dem Stand der Technik bekannten Radsatzlenker dazu, für Kurvenfahrten eine Drehbewegung des Radsatzes gegenüber dem Fahrzeugrahmen beziehungsweise dem Drehgestellrahmen zu erlauben, um somit den Anstellwinkel der Räder gegenüber den Schienen zu minimieren. Entsprechend der in den voranstehend genannten Druckschriften offenbarten Anordnung wird hierzu die durch Fliehkräfte in Kurvenfahrten ausgelöste axiale Bewegung des Radsatzes in die gewünschte Drehung und damit einen gewissen Winkel der Räder zum Rahmen umgesetzt. Auch für diesen Fall ist es notwendig, dass die vom Radsatzlenker erzeugten Querkräfte im hinreichenden Maß über eine Befestigung vom Radsatzlenker auf das Radsatzlagergehäuse übertragen werden.The stabilization of the wheel set generated by the Radsatzlenker serves different purposes. On the one hand, the wheelset is to stabilize when driving straight ahead in the axial direction, which is essential especially in high-speed driving and defective track bodies. By the lateral forces applied by the wheel set linkage vibrations on the wheel set can be suppressed and both the comfort and the driving safety of the rail vehicle can be improved. In addition, those from the prior art known Radsatzlenker to allow for cornering a rotational movement of the wheelset relative to the vehicle frame or the bogie frame, thus minimizing the angle of attack of the wheels relative to the rails. According to the disclosed in the above-mentioned publications arrangement, this is triggered by centrifugal forces in cornering axial movement of the wheel set in the desired rotation and thus a certain angle of the wheels to the frame. Also for this case, it is necessary that the lateral forces generated by the Radsatzlenker are transmitted to a sufficient extent via an attachment from the Radsatzlenker on the Radsatzlagergehäuse.

Aus der DE 33 11 757 A1 ist eine Lagerung für einen Radsatzlenker bekannt geworden, welcher sich durch querverlaufende Gelenkbolzen mit kreisschnittförmig ausgestalteten Endflächen auszeichnet, welche wiederum von randoffenen Ausnehmungen am Rahmen aufgenommen und mit einem verschraubbaren Steg abgedeckt werden. Die offenbarte Befestigung ist konstruktiv aufwendig, sie besteht zum einen aus mehreren Einzelkomponenten, welche zur Erzielung eines hinreichenden Formschlusses aufwendig bearbeitet werden müssen. Zum anderen ist der Zusammenbau und der Austausch des Radlenkersatzes aufwendig.From the DE 33 11 757 A1 is a storage for a Radsatzlenker become known, which is characterized by transverse hinge pin with circular-section end faces configured, which in turn are recorded by open-edged recesses on the frame and covered with a screwed web. The disclosed attachment is structurally complex, it consists on the one hand of several individual components, which must be processed consuming to achieve a sufficient fit. On the other hand, the assembly and replacement of Radlenkersatzes consuming.

DE 19 36 932 A1 beschreibt ein Drehgestell für Schienenfahrzeuge mit Einzelradaufhängung der Radsätze umfassend einen Rahmen mit einer kastenförmigen Traverse, die mittels Kugelgelenken an Lenkern angelenkt ist. Dabei verlaufen die Gelenkbolzen der Lenker in Vertikalrichtung. Dabei reicht der Gelenkbolzen über die vertikale Erstreckung der Lenker hinaus, um das Kugelgelenk mittels jeweils zwei Muttern zu fixieren DE 19 36 932 A1 describes a bogie for rail vehicles with independent suspension of the wheelset comprising a frame with a box-shaped cross member, which is articulated by means of ball joints to the handlebars. The hinge pins of the handlebars extend in the vertical direction. The hinge pin extends beyond the vertical extension of the handlebars to fix the ball joint by means of two nuts

Einfache Ausgestaltungen der Befestigungspunkte für Radsatzlenker umfassen am Ende des Radsatzlenkers eine Bohrung, welche der Aufnahme eines Gelenklagers mit einer Lagerschale sowie einem Gelenkbolzen dient. Hierbei ist wenigstens ein Teil dieser Lagerschale ein in die Aufnahme eingepresstes oder eingeklebtes Element. Auch Verschraubungen sind denkbar. Nachteilig an diesem Ansatz ist jedoch, dass die bekannten Verbindungen des Gelenkbolzens mit dem Lagergehäuse des Radsatzlagers entweder konstruktiv aufwendig und in vertikaler Richtung großbauend sind oder nicht im hinreichenden Maße die vom Radsatzlenker übertragenen Querkräfte auf das Gehäuse des Radsatzlagers und entsprechend den Rahmen einleiten können, da der Presssitz oder die Verklebung der Lagerschale diesen Kräften nicht widerstehen kann.Simple embodiments of the attachment points for Radsatzlenker include at the end of the Radsatzlenkers a bore which serves to receive a joint bearing with a bearing shell and a hinge pin. Here, at least a part of this bearing shell is pressed into the receptacle or glued element. Also glands are conceivable. A disadvantage of this approach, however, is that the known compounds of the hinge pin with the bearing housing of the wheelset bearing either structurally complex and großbauend in the vertical direction or can not initiate to a sufficient extent transmitted by the Radsatzlenker shear forces on the housing of the wheelset bearing and according to the frame the interference fit or the bonding of the bearing shell can not withstand these forces.

Der Erfindung liegt die Aufgabe zugrunde, die Nachteile der bekannten Befestigungen für Radsatzlenker zu überwinden und eine in der Fertigung und für den Zusammenbau konstruktiv einfache Befestigung anzugeben, welche sowohl Längs- wie Querkräfte vom Radsatzlenker auf das Lagergehäuse für den Radsatz beziehungsweise in umgekehrter Richtung vom Lagergehäuse auf den Fahrzeugrahmen beziehungsweise dem Drehgestellrahmen übertragen kann. Die Aufgabe wird mittels der Merkmale des Anspruchs 1 gelöst.The invention has for its object to overcome the disadvantages of the known fasteners for Radsatzlenker and provide a structurally simple in the manufacture and assembly simple attachment, which both longitudinal and lateral forces from Radsatzlenker on the bearing housing for the wheel or in the reverse direction of the bearing housing can transmit to the vehicle frame or the bogie frame. The object is achieved by means of the features of claim 1.

Zur Lösung haben die Erfinder erkannt, dass ausgehend von einem gattungsgemäßen Gelenklager für einen Radsatzlenker mit einer eingepressten, eingeklebten oder eingeschraubten Lagerschale der Lagerbolzen vorteilhaft senkrecht ausgerichtet werden muss, um Querkräfte unmittelbar über die Lagerschalen auf das Material der Aufnahme und damit effektiv vom Gehäuse beziehungsweise dem Rahmen des Fahrzeugs auf den Radsatzlenker übertragen werden kann.To solve the inventors have recognized that starting from a generic spherical plain bearing for a Radsatzlenker with a pressed, glued or screwed bearing shell of the bearing pin must be aligned vertically perpendicular to shear forces directly on the bearing shells on the material of the recording and thus effectively from the housing or the Frame of the vehicle can be transferred to the Radsatzlenker.

Erfindungsgemäß wurden die bekannten Ausgestaltungen mit einem senkrecht gestellten Gelenkbolzen so weiterentwickelt, dass jenes Element, welches die elastische Lagerschale aufnimmt und der Aufnahme des Gelenkbolzens dient, nicht Teil des Radsatzlenkers selbst ist, sondern ein separates Befestigungselement darstellt, welches mit dem Lagergehäuse des Radsatzes beziehungsweise dem Fahrzeugrahmen verschraubt wird. Die Verbindung zwischen diesem Befestigungselement und dem Radsatzlenker wird dann über den Gelenkbolzen erreicht, welcher in beiden Richtungen über die Lagerschale hinaussteht, das heißt er weist ein erstes Ende sowie ein zweites Ende auf, welche jeweils von Teilen des Radsatzlenkers aufgenommen werden. Hierbei ist eine form- oder kraftschlüssige Verbindung oder eine Verschraubung des ersten Endes beziehungsweise des zweiten Endes des Gelenkbolzens mit den zugeordneten Tragkomponenten auf dem Radsatzlenker möglich.According to the known embodiments were further developed with a vertical hinge pin so that that element which receives the elastic bearing shell and the inclusion of the hinge pin is not part of the wheel set itself, but a separate fastener is, which with the bearing housing of the wheelset or the Vehicle frame is bolted. The connection between this fastener and the Radsatzlenker is then reached via the hinge pin, which protrudes in both directions beyond the bearing shell, that is, it has a first end and a second end, which are each received by parts of the Radsatzlenkers. Here, a positive or non-positive connection or a screw connection of the first end or the second end of the hinge pin with the associated supporting components on the Radsatzlenker is possible.

Besonders bevorzugt wird eine Ausgestaltung eines Radsatzlenkers mit einem gabelförmigen Ende, wobei jeweils die Schenkel dieser Gabel eine Verbindung zum ersten beziehungsweise dem zweiten Ende des Gelenkbolzens aufweisen.Particularly preferred is an embodiment of a Radsatzlenkers with a fork-shaped end, wherein in each case the legs of this fork have a connection to the first and the second end of the hinge pin.

Gemäß einer Weiterentwicklung wird statt des gabelförmigen Endes zur Befestigung des ersten Endes und des zweiten Endes des Gelenkbolzens ein zweiteiliger Radsatzlenker verwendet, wobei ein erster oberer Teil des Radsatzlenkers dem ersten Ende des Gelenkbolzens, welches nach oben aus der Lagerschale heraussteht, zugeordnet ist. Entsprechend wird ein zweiter, unterer Teil des Radsatzlenkers mit dem zweiten, nach unten aus der Lagerschale herausstehenden Ende des Gelenkbolzens verbunden.According to a further development, a two-piece wheelset is used instead of the forked end for fastening the first end and the second end of the hinge pin, wherein a first upper part of the Radsatzlenkers the first end of the hinge pin, which protrudes up out of the bearing shell assigned. Accordingly, a second, lower part of the Radsatzlenkers with the second, down from the bearing shell protruding end of the hinge pin is connected.

Durch die erfindungsgemäße Befestigung des Radsatzlenkers kann ein senkrecht stehender Gelenkbolzen und damit eine hinreichende Querkraftübertragung sichergestellt werden. Darüber hinaus zeichnet sich die Befestigung durch ihre konstruktive Einfachheit aus, welche es erlaubt, den Radsatzlenker einfach zu montieren. Dies betrifft sowohl die Erstmontage, wie auch ein Ersatz des Gelenkbolzens oder eine Demontage im Zusammenhang mit der Wartungen des Radsatzes.The inventive attachment of the Radsatzlenkers a vertical hinge pin and thus a sufficient lateral force transmission can be ensured. In addition, the attachment is characterized by its constructive simplicity, which makes it easy to mount the Radsatzlenker. This concerns both the initial assembly, as well as a replacement of the hinge pin or disassembly in connection with the maintenance of the wheelset.

Die einfache Montage beruht auf der erfindungsgemäßen Trennung des die Lagerschale aufnehmenden Befestigungselements vom Radsatzlenker selbst. Hierdurch kann neben der Senkrechtstellung des Gelenkbolzens eine solche Befestigung dieses Befestigungselements erreicht werden, bei dem die Befestigungsmittel, beispielsweise Schraubverbindungen beidseits des Gelenkbolzens positioniert sind. Hieraus ergibt sich der Vorteil, dass ein zunächst komplett als Bauteil zusammengesetztes Element aus dem Radsatzlenker, dem Gelenkbolzen und dem Verbindungselement mit dem Lagergehäuse beziehungsweise dem Fahrzeugrahmen verschraubt werden kann, da die seitlich neben dem Gelenkbolzen und damit auch zu beiden Seiten des Radsatzlenkers angeordneten Befestigungsmittel zugänglich und damit handhabbar sind. Nachfolgend wird die Erfindung anhand von Figuren und durch ein Ausführungsbeispiel genauer beschrieben. In den Figuren ist im Einzelnen folgendes dargestellt:

Figur 1

stellt in schematisch vereinfachter dreidimensionaler Darstellung einen Radsatz mit einem Radsatzlager in Verbindung mit Radsatzlenkern gemäß dem Stand der Technik dar.
The simple assembly is based on the inventive separation of the bearing shell receiving fastener from Radsatzlenker itself. In addition to the vertical position of the hinge pin such attachment of this fastener can be achieved, in which the fastening means, such as screw are positioned on both sides of the hinge pin. This results in the advantage that an initially completely assembled as a component element from the Radsatzlenker, the hinge pin and the connecting element with the bearing housing or the vehicle frame can be screwed, as the laterally next to the hinge pin and thus arranged on both sides of the Radsatzlenkers fastener accessible and thus manageable. The invention will be described in more detail below with reference to figures and by an embodiment. The following is shown in detail in the figures:

Figur 4 zeigt einen Radsatz 2 für ein Schienenfahrzeug gemäß dem Stand der Technik, welcher durch ein Radsatzlager 3, welches von einem Radsatzlagergehäuse 4 umgeben ist, gelagert wird. Über die im Wesentlichen senkrecht angeordneten Federn 5 erfolgt eine Abstützung auf den Fahrzeugrahmen oder einem Drehgestellrahmen. Diese senkrechten Federn 5 federn Stöße vom Gleiskörper auf den Fahrzeugkasten beziehungsweise auf das Drehgestell ab. Vorteilhafterweise sind sie auf diese Hauptaufgabe abgestimmt, das heißt insbesondere Querkräfte werden durch weitere Komponenten aufgenommen. Entsprechend des Stands der Technik dienen wenigstens teilweise die Radsatzlenker 6 diesem Zweck, welche gemäß der in Figur 4 gezeigten Darstellung binär, das heißt mit zwei Gelenken 7.1, 7.2 ausgestaltet sein können . Für eine zweigelenkige Ausbildung sind die Radsatzienker 6 bevorzugt schrägstehend zur Längsachse des Fahrzeugs beziehungsweise des Drehgestellrahmens ausgerichtet, um sowohl eine bessere Querstabilisierung zu ermöglichen, wie auch für die Kurvenfahrt eine durch Fliehkräfte verursachte Axialbewegung des Radsatzes in eine Verdrehung relativ zum Fahrzeugrahmen beziehungsweise dem Drehgestellrahmen umzuwandeln und so eine an den Kurvenverlauf der Schiene angepasste Stellung des Radsatzes zu ermöglichen. FIG. 4 shows a wheel set 2 for a rail vehicle according to the prior art, which is supported by a wheelset bearing 3, which is surrounded by a wheelset bearing housing 4. About the substantially vertically arranged springs 5 is a support to the vehicle frame or a bogie frame. These vertical springs 5 absorb shocks from the track body on the vehicle body or on the bogie. Advantageously, they are tuned to this main task, that is, in particular lateral forces are absorbed by other components. According to the prior art serve at least partially the Radsatzlenker 6 this purpose, which according to the in FIG. 4 shown representation binary, that can be configured with two joints 7.1, 7.2. For a zweigelenkige training the Radsatzienker 6 are preferably oriented obliquely to the longitudinal axis of the vehicle or the bogie frame to allow both a better lateral stabilization, as well as for cornering through Centrifugal forces caused axial movement of the wheelset in a rotation relative to the vehicle frame or the bogie frame and thus to allow adapted to the curve of the rail position of the wheelset.

Neben der binären Ausführung der Radsatzlenker 6 sind auch Radsatzlenker 6 mit mehreren Gelenken, insbesondere Dreiecksanordnungen denkbar. Darüber hinaus kann abweichend zu Figur 4 der Radsatzlenker auch zu beiden Seiten eines einzelnen Radsatzes angeordnet sein.In addition to the binary version of the Radsatzlenker 6 and Radsatzlenker 6 with multiple joints, in particular triangular arrangements are conceivable. In addition, deviating too FIG. 4 the wheelset also be arranged on both sides of a single wheel.

Figur 2 zeigt eine dem Stand der Technik entsprechende Anordnung, bei der der Radsatzlenker 6 ein Gelenk mit einem horizontal angeordneten Gelenkbolzen 11 aufweist. Im Folgenden wird anstatt des Ausdrucks "Gelenk" verallgemeinert von einer Befestigung zum Radsatzlagergehäuse oder dem Rahmen des Fahrzeugs oder des Drehgestells gesprochen, worunter sowohl die Elemente des Gelenklagers, umfassend einen Gelenkbolzen und die Lagerschale, sowie die entsprechenden Aufnahmen und Befestigungsmittel sowohl zum Radsatzlenker, wie auch zum Gehäuse beziehungsweise Rahmen verstanden werden. FIG. 2 shows a prior art arrangement in which the Radsatzlenker 6 has a hinge with a horizontally arranged hinge pin 11. Hereinafter, instead of the term "joint" is generalized by an attachment to the wheelset bearing housing or the frame of the vehicle or the bogie, including both the elements of the joint bearing, comprising a hinge pin and the bearing shell, and the corresponding receptacles and fasteners both to Radsatzlenker how also be understood to the housing or frame.

Die schematische Darstellung von Figur 2 stellt in einem Axialschnitt zum Radsatzlager einen Radsatzlenker 6 mit einer Bohrung an dem zum Radsatzlagergehäuse hinweisenden Ende dar. Diese dient als Aufnahme 10 für eine Lagerschale 13, welche wiederum den Lagerbolzen 11 führt. Die Lagerschale 13 wird bevorzugt aus einem verschleißfreien Ring aus einem Elastomermaterial hergestellt und erlaubt in gewissem Maße eine kardanische Bewegung des Radsatzlenkers 6 relativ zum Gehäuse oder zum Rahmen. Im Rahmen des fachmännischen Könnens kann die Lagerschale 13 auch abweichend gestaltet sein und insbesondere im Wesentlichen unelastische Komponenten, etwa aus Teflon oder Stahl, etwa für die Gleitflächen, umfassen. Entsprechend kann die geforderte beschränkte dreidimensionale Beweglichkeit des Gelenklagers auch durch eine entsprechende Ausformung der Ablaufflächen, über die der Lagerbolzen 11 gleitet, bewirkt werden.The schematic representation of FIG. 2 in an axial section to the wheelset bearing a Radsatzlenker 6 with a bore at the pointing to the Radsatzlagergehäuse end. This serves as a receptacle 10 for a bearing shell 13, which in turn leads the bearing pin 11. The bearing shell 13 is preferably made of a wear-free ring made of an elastomeric material and allows to a certain extent a gimbal movement of the Radsatzlenkers 6 relative to the housing or the frame. Within the scope of skill in the art, the bearing shell 13 can also be deviating in design and, in particular, essentially comprise inelastic components, for example made of Teflon or steel, for example for the sliding surfaces. Accordingly, the required limited three-dimensional mobility of the joint bearing can also be effected by a corresponding shaping of the running surfaces over which the bearing pin 11 slides.

Der horizontal liegende Gelenkbolzen 11 wird über ein Befestigungsmittel 8, insbesondere eine Schraube, mit dem Lagergehäuse 4 verbunden. Üblicherweise werden hierbei wenigstens zwei Befestigungspunkte verwendet, so dass Verbindungspunkte auf beiden Seiten der Lagerschale entstehen.The horizontal hinge pin 11 is connected via a fastening means 8, in particular a screw, with the bearing housing 4. Usually, in this case at least two attachment points are used, so that connection points arise on both sides of the bearing shell.

Eine Montage dieser Anordnung ist einfach, da die jeweils neben den Radsatzlenkern liegenden Befestigungspunkte leicht zugänglich sind und die Bauhöhe der Anordnung im Wesentlichen durch die notwendige Größendimensionierung der Lagerschale 13 und der Aufnahme 10 bestimmt wird.An assembly of this arrangement is simple, since each lying next to the wheelset mounting points are easily accessible and the height of the arrangement is determined essentially by the necessary size dimensioning of the bearing shell 13 and the receptacle 10.

Nachteilig an der bekannten Anordnung ist jedoch, dass die Lagerschale 13, welche üblicherweise in die Aufnahme 10 eingepresst oder eingeklebt ist, nicht im hinreichenden Maße Querkräfte aufnehmen kann, so dass entweder von den senkrechten Federn 5 über dem Radsatzlager 6 Querkräfte aufgenommen werden müssen oder die Befestigung 1 lediglich im Hinblick auf die Querkraftrichtung großbauend auszubilden ist.A disadvantage of the known arrangement, however, is that the bearing shell 13, which is usually pressed or glued into the receptacle 10, can not absorb transverse forces to a sufficient extent, so that either from the vertical springs 5 on the wheelset 6 transverse forces must be taken or the Attachment 1 is designed to be large-building merely with regard to the transverse force direction.

Figur 3 zeigt eine senkrechte Anordnung des Gelenkbolzens 11, welche das Problem einer quersteifen Befestigung 1 realisiert. Querkräfte werden nicht über den Presssitz oder die Verklebung auf den Radsatzlenker 6, sondern quer zum Gelenkbolzen 11 und damit unmittelbar auf die Lagerschale 13 und die Wandung der Ausnehmung, die als Aufnahme 10 dient, zum Radsatzlenker 6 übertragen. Nachteilig an dieser bekannten Ausgestaltung ist jedoch, dass aufgrund der senkrechten Anordnung des Gelenkbolzens 11 auch die Befestigungsmittel 8 zum Radlagergehäuse 4 ober- und unterhalb der Lagerschale 13 angeordnet sind. Dies führt zu dem Nachteil, dass der Bauraum der Befestigung in vertikaler Richtung zunimmt und bei der Montage der Radsatzlenker 6 den Zugang zu den Befestigungsmitteln erschwert ist. FIG. 3 shows a vertical arrangement of the hinge pin 11, which realizes the problem of a transversely rigid attachment 1. Transverse forces are not transmitted to the Radsatzlenker 6 via the press fit or the bond on the Radsatzlenker 6, but transversely to the hinge pin 11 and thus directly on the bearing shell 13 and the wall of the recess, which serves as a receptacle 10. A disadvantage of this known embodiment, however, is that due to the vertical arrangement of the hinge pin 11 and the fastening means 8 are arranged to the wheel bearing housing 4 above and below the bearing shell 13. This leads to the disadvantage that the installation space of the attachment in the vertical direction increases and in the assembly of the wheelset 6 access to the fastening means is difficult.

Figur 1 zeigt eine erfindungsgemäße Befestigung 1 eines Radsatzlenkers 6 an einem Radsatzlagergehäuse 4, die die Vorteile eines senkrecht liegenden Gelenkbolzens 11 mit einer guten Montagefähigkeit und einer insgesamt kleinbauenden Einheit verbindet. Erfindungsgemäß wird die Lagerschale 13 in einer Aufnahme 10 eines zum Radsatzlenker 6 separaten Befestigungselements 14 ausgebildet. Dies erlaubt es einen Gelenkbolzen 11 mit beidseits zum Radsatzlager 3 angeordneten Befestigungsmitteln 8 zu verbinden. Gleichzeitig begrenzen nur die aus den Lagerschalen 13 herausragenden Enden des senkrechten Gelenkbolzens 11, welche nachfolgend als das erste Ende 11.1, welches oberhalb der Lagerschale 13 liegt, und als zweites Ende 11.2, welches unterhalb der Lagerschale 13 liegt, bezeichnet werden, die Baugröße der erfindungsgemäßen Befestigung in vertikaler Richtung. FIG. 1 shows a fastening according to the invention 1 a Radsatzlenkers 6 on a wheelset bearing housing 4, which has the advantages of a vertical Joint bolt 11 with a good mounting capability and a total of small unit connects. According to the invention, the bearing shell 13 is formed in a receptacle 10 of a separate to the Radsatzlenker 6 fastener 14. This makes it possible to connect a hinge pin 11 with fixing means 8 arranged on both sides of the wheel set bearing 3. At the same time limit only the protruding from the bearing shells 13 ends of the vertical hinge pin 11, which hereinafter referred to as the first end 11.1, which is above the bearing shell 13, and the second end 11.2, which is below the bearing shell 13, the size of the invention Attachment in the vertical direction.

Das erste Ende des Gelenkbolzens 11.1 steht in Verbindung mit einem ersten, oberen Endstück des Radsatzlenkers 6.1. Das zweite Ende des Gelenkbolzens 11.2 ist entsprechend mit einem zweiten, unteren Endstück des Radsatzlenkers 6.2 verbunden. Diese Verbindungen können durch einen Presssitz, eine Verklebung, eine Verschraubung oder durch Formschluss erfolgen. Darüber hinaus können das erste, obere Endstück 6.1 und das zweite, untere Endstück des Radsatzlenkers 6 Teil einer Gelenkgabel am Ende des Radsatzlenkers 6 sein, wobei diese dann die Schenkel der Gabel darstellen und über eine Stegverbindung mit dem restlichen Teil des Radsatzlenkers 6 verbunden sind.The first end of the hinge pin 11.1 is in communication with a first, upper end of the Radsatzlenkers 6.1. The second end of the hinge pin 11.2 is correspondingly connected to a second, lower end piece of the Radsatzlenkers 6.2. These connections can be made by a press fit, a bond, a screw or by positive locking. In addition, the first, upper end 6.1 and the second, lower end of the Radsatzlenkers 6 may be part of a yoke at the end of the Radsatzlenkers 6, which then represent the legs of the fork and are connected via a web connection with the remaining part of the Radsatzlenkers 6.

Denkbar ist auch eine Ausgestaltung, bei dem das erste, obere Endstück 6.1 und das zweite, untere Endstück 6.2 des Radsatzlenkers 6 getrennte Bauteile darstellen, wodurch die Montage vereinfacht wird, da beim Zusammenbau keine Fluchtung zwischen der Lagerschale 13 im separaten Befestigungselement 14 und den Bohrungen im Schenkel der Gelenkgabel hergestellt werden muss. Stattdessen kann zunächst der Gelenkbolzen 11 mit dem unteren oder dem oberen Teil des Radsatzlenkers 6 verbunden werden und sodann kann ein Aufstecken der Lagerschale beziehungsweise des separaten Befestigungselements 14 erfolgen.Also conceivable is an embodiment in which the first, upper end piece 6.1 and the second, lower end 6.2 of the Radsatzlenkers 6 represent separate components, whereby the assembly is simplified because during assembly no alignment between the bearing shell 13 in the separate fastener 14 and the holes in the leg of the yoke must be made. Instead, first, the hinge pin 11 can be connected to the lower or the upper part of the Radsatzlenkers 6 and then attaching the bearing shell or the separate fastener 14 can be carried out.

Die Montage eines Radsatzlenkers 6 mit einer erfindungsgemäßen Befestigung 1 ist vorteilhaft einfach, da die beiden jeweils beidseits zum Gelenkbolzen 11 angeordneten Befestigungspunkte zum Radsatzlagergehäuse 4 beziehungsweise zum Rahmen leicht zugänglich sind. Die Handhabung wird ferner dadurch verbessert, dass diese Befestigungspunkte im Wesentlichen horizontal verlaufend angeordnet sind.The mounting of a Radsatzlenkers 6 with a fastening 1 according to the invention is advantageously simple, since the two are arranged on both sides of the hinge pin 11 mounting points for Radsatzlagergehäuse 4 or to the frame easily accessible. The handling is further improved by the fact that these attachment points are arranged to extend substantially horizontally.

Voranstehend wurde die Erfindung anhand einer Ausgestaltung für eine Befestigung zum Radsatzlagergehäuse 4 dargestellt. Die weiteren Gelenke beziehungsweise Befestigungen des Radsatzlenkers 6 am Fahrzeugrahmen beziehungsweise dem Drehgestellrahmen können gemäß einer vorteilhaften Ausgestaltung ebenfalls einen Aufbau umfassend ein separates Befestigungselement 14 mit einem darin senkrecht angeordneten Gelenkbolzen aufweisen, so dass sich die entsprechenden Vorteile bezüglich der Montagefähigkeit sowie eine Bauraumeinsparung auch für diese Gelenkpunkte realisieren lassen.The invention has been described above with reference to an embodiment for attachment to the wheel set bearing housing 4. The other joints or attachments of the Radsatzlenkers 6 on the vehicle frame or the bogie frame can also according to an advantageous embodiment comprising a structure comprising a separate fastener 14 having a vertically disposed hinge pin, so that the corresponding advantages in terms of mounting capability and a space savings for these hinge points let realize.
