Drehgestell für SchienenfahrzeugeBogie for rail vehicles
Beschreibungdescription
Die Erfindung bezieht sich auf ein Drehgestell fürThe invention relates to a bogie for
Schienenfahrzeuge mit einein Rahmen, zwei Radsätzen und einem Lenkgestänge zum Erzielen radialer Einstellungen der Radsätze in Gleisbogen, wobei zwischen dem Drehge¬ stellrahmen und Lagern der Radsätze Federn angeordnet sind und das Lenkgestänge an den Radsatzlagern unterhalb deren horizontaler Mittenebene angeschlossen ist.Rail vehicles with a frame, two wheel sets and a steering linkage for achieving radial settings of the wheel sets in track bends, springs being arranged between the bogie frame and bearings of the wheel sets and the steering linkage being connected to the wheel set bearings below their horizontal center plane.
Ein Drehgestell mit den zuvor genannten Merkmalen ist durch die DE-OS 34 24 531 bekannt, siehe Fig. 4 und 5. Bei diesem Drehgestell sind die nach Art eines hängenden Pendels am Rahmen gehaltenen Radsatzlager durch ein sogenanntes Watt-Gestänge (siehe insbesondere Fig. 2) kurvenradial einstellbar gekoppelt. Zur Stabilisierung der Radsätze sind zusätzliche, diagonal zueinander verlaufende Lenker (Fig. 13) vorgesehen, die wegen des hohen baulichen Aufwandes als nachteilig angesehen werden.A bogie with the aforementioned features is known from DE-OS 34 24 531, see FIGS. 4 and 5. In this bogie, the wheelset bearings held in the manner of a hanging pendulum on the frame are by a so-called wattage linkage (see in particular Fig. 2) Coupled with radial adjustment. To stabilize the wheel sets, additional diagonally extending links (FIG. 13) are provided, which are considered disadvantageous because of the high structural complexity.
Der Erfindung liegt die Aufgabe zugrunde, durch einfache Mittel eine weitgehend verschleißfreie Anbindung derThe invention is based, simple means a largely wear-free connection of the task
Radsätze am Drehgestellrahmen zu erzielen, die radiale Einstellungen der Radsätze in Gleisbogen zuläßt.To achieve wheel sets on the bogie frame, which allows radial settings of the wheel sets in track bends.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Radsatzlager jeweils durch einen oberhalb der hori¬ zontalen Mittenebene angreifenden Blattlenker am Drehge¬ stellrahmen in Längs- und Querrichtung geführt sind, wobei jeder Blattlenker federnd gestaltet und parallel zu den Federn wirksam ist.This object is achieved in that the wheelset bearings are each guided in the longitudinal and transverse directions by a leaf link on the bogie frame which engages above the horizontal central plane, each leaf link is resilient and effective parallel to the springs.
Durch die federnd gestalteten, in die Primärfederung des Drehgestells integrierten Blattlenker werden alle Quer¬ kräfte zwischen den Radsätzen und dem Drehgestellrahmen übertragen, d. h., die Blattlenker übernehmen auch die Querführung der Radsätze. Im geraden Gleis ergeben die Blattlenker im Zusammenwirken mit dem Lenkgestänge außerdem einen starren rahmenseitigen Anschluß derDue to the resiliently designed leaf link integrated in the primary suspension of the bogie, all transverse forces are transmitted between the wheel sets and the bogie frame, i. that is, the leaf links also take over the lateral guidance of the wheel sets. In a straight track, the leaf links in cooperation with the steering linkage also result in a rigid connection to the frame
Radsätze in Längsrichtung, der für die Achsparallelität wichtig ist. Im Hinblick auf das Befahren von Gleisbogen dienen die Blattlenkeranschlüsse der Radsatzlager als Drehpunkte, die radiale Einstellungen der Radsätze durch das Kräftegleichgewicht zwischen Rad und Schiene im Verhältnis zum Gleisbogen erlauben.Longitudinal wheel sets, which is important for parallelism of the axles. With regard to traversing track bends, the leaf link connections of the wheelset bearings serve as pivot points, which allow radial adjustments of the wheel sets due to the balance of forces between wheel and rail in relation to the track bend.
Um den Einfluß von Spiel in den Gelenken des Lenkgestän¬ ges auf die Radialeinstellungen der Radsätze möglichst gering zu halten, ist nach einer Ausgestaltung derIn order to keep the influence of play in the joints of the steering linkage on the radial settings of the wheel sets as low as possible, according to one embodiment the
Erfindung vorgesehen, daß der Blattlenker und das Lenk¬ gestänge in bezug auf die horizontale Mittenebene derart asymetrisch mit dem jeweiligen Radsatzlager verbunden sind, daß der lenkerseitige Hebelarm kleiner ist als der gestängeseitige Hebelarm.According to the invention, the leaf link and the steering linkage are connected asymmetrically to the respective wheel set bearing with respect to the horizontal center plane such that the lever arm on the handlebar side is smaller than the lever arm on the linkage.
Im Hinblick auf verschleißfreie Schwenkbewegungen des Radsatzlagers um den am Blattlenker bestehenden Drehpunkt liegt eine weitere Ausführungsform der Erfindung darin, daß der Blattlenker durch eine Gummi-Metall-Buchse am Radsatzlager angeschlossen ist.With regard to wear-free pivoting movements of the wheel set bearing about the pivot point existing on the leaf link, a further embodiment of the invention is that the leaf link is connected to the wheel set bearing by a rubber-metal bushing.
Gemäß einer nächsten Ausgestaltung der Erfindung können exakte Maßverhältnisse auf montagefreundliche Weise dadurch erreicht werden, daß der Blattlenker in Längs¬ richtung einstellbar mit dem Drehgestellrahmen verbunden ist, vorzugsweise über korrespondierende Zahnleisten. Im weiteren wird die Erfindung anhand eines Ausführungs- beispiels näher beschrieben, das in der Zeichnung sche¬ matisch dargestellt ist. Es zeigenAccording to a next embodiment of the invention, exact dimensions can be achieved in an assembly-friendly manner by the fact that the leaf link is connected to the bogie frame so as to be adjustable in the longitudinal direction, preferably via corresponding toothed strips. The invention is described in more detail below with the aid of an exemplary embodiment which is shown schematically in the drawing. Show it
Fig. 1 ein Drehgestell in perspektivischer Ansicht,1 is a bogie in perspective view,
Fig. 2 einen Teilbereich des Drehgestells in Seitenansicht.Fig. 2 shows a partial area of the bogie in side view.
Das Drehgestell hat zwei Radsätze 2 mit zugehörigen Rad¬ satzlagern 4, wobei zwischen diesen Lagern 4 und dem Drehgeεtellrahmen 1 als Primärfedern dienende Federn 5 angeordnet sind. An jedem Radsatzlager 4 greift oberhalb der horizontalen Mittenebene M unter Einschaltung einer Gummi-Metall-Buchse 7 ein Blattlenker 6 an, der anderer¬ seits am Drehgestellrahmen 1 eingespannt ist. Im Bereich dieser Einspannstelle ausgebildete korrespondierende Zahnleisten la und 6a ermöglichen auf einfache Weise das maßgenaue Einstellen der Radsätze 2. Durch die Blattlen- ker 6 werden die Radsatzlager 4 in Längs- und Querrich¬ tung am Drehgestellrahmen 1 geführt. Die Blattlenker 6 sind federnd gestaltet und zusammen mit ihrer Gummi-Me¬ tall-Buchse 7 in allen Richtungen parallel zu den Federn 5 wirksam; sie sind also Bestandteil der Primärfederung.The bogie has two wheel sets 2 with associated wheel set bearings 4, springs 5 serving as primary springs being arranged between these bearings 4 and the rotary frame 1. At each wheel set bearing 4, above the horizontal center plane M, a leaf link 6, which is clamped on the bogie frame 1, engages with the activation of a rubber-metal bushing 7. Corresponding toothed ridges 1a and 6a formed in the area of this clamping point enable the wheel sets 2 to be adjusted in a simple manner by means of the leaf links 6, the wheel set bearings 4 are guided on the bogie frame 1 in the longitudinal and transverse directions. The leaf links 6 are designed to be resilient and, together with their rubber-metal bushing 7, are effective in all directions parallel to the springs 5; So they are part of the primary suspension.
Unterhalb der horizontalen Mittenebene M der Radsatzlager 4 ist ein Lenkgestänge 3 angeschlossen, das aus Lenk¬ stangen 3a, am Drehgestellrahmen 1 gelagerten Umlenkhe¬ beln 3b und einer die Umlenkhebel 3b verbindenden Quer- stange 3c besteht. Zwischen der Querstange 3c des Lenk- gestänges 3 und dem Drehgestellrahmen 1 ist ein Quer¬ dämpfer 8 angeordnet. Das gesamte Lenkgestänge 3 liegt in der Horizontalen, so daß die Einbauhöhe im Drehgestell sehr gering ist. Das Lenkgestänge 3 ermöglicht in Gleis- bogen das gegenläufige Verdrehen der beiden Radsätze 2 um ihre mittlere Hochachse H im Sinne radialer Einstel¬ lungen. Dabei schwenken die Radsatzlager 4 um die durch die Gummi-Metall-Buchse 7 der Blattlenker 6 gebildeten Drehpunkte. Wie aus Fig. 2 ersichtlich, sind die Blatt¬ lenker 6 und die Lenkstangen 3a des Lenkgestänges 3 in bezug auf die horizontale Mittenebene M asymetrisch mit dem Radsatzlager 4 verbunden, wobei der lenkerseitige Hebelarm a kleiner ist als der gestängeseitige Hebelarm b. Dadurch wird der Einfluß von Spiel in den Gelenken des Lenkgestänges 3 auf die Radialeinstellungen der Radsätze 4 gering gehalten.Below the horizontal center plane M of the wheelset bearings 4, a steering linkage 3 is connected, which consists of steering rods 3a, deflection levers 3b mounted on the bogie frame 1 and a crossbar 3c connecting the deflection levers 3b. A transverse damper 8 is arranged between the cross bar 3c of the steering linkage 3 and the bogie frame 1. The entire steering linkage 3 is horizontal, so that the installation height in the bogie is very low. The steering linkage 3 enables the two wheel sets 2 to be rotated in opposite directions about their central vertical axis H in the sense of radial settings. The wheelset bearings 4 swivel through the rubber-metal bushing 7 of the leaf guide 6 pivots formed. As can be seen from FIG. 2, the leaf links 6 and the steering rods 3a of the steering linkage 3 are connected asymmetrically to the wheel set bearing 4 with respect to the horizontal center plane M, the lever arm a on the handlebar side being smaller than the lever arm b on the rod side. As a result, the influence of play in the joints of the steering linkage 3 on the radial settings of the wheel sets 4 is kept low.
Das Drehgestell in der Anordnung gemäß Fig. 1 ist selbsteinstellend, d. h., radiale Einstellungen der Radsätze 2 ergeben sich aus dem Kräftegleichgewicht zwischen Rad und Schiene im Verhältnis zum Gleisbogen. Diese Selbsteinstellungen werden erheblich begünstigt durch ein auf die Schiene abgestimmtes Profil der Rad¬ bandage in Form eines Hohl- oder Anpassungsprofils mit progressiv zunehmendem Laufkreisdurchmesser in Richtung auf den Spurkranz .The bogie in the arrangement of FIG. 1 is self-adjusting, i. That is, radial settings of the wheel sets 2 result from the balance of forces between the wheel and the rail in relation to the track curve. These self-adjustments are considerably favored by a profile of the wheel bandage which is matched to the rail in the form of a hollow or adaptation profile with a progressively increasing tread diameter in the direction of the wheel flange.
Durch geringfügiges Abwandeln der in Fig. 1 gezeigten Anordnung können direkt vom Ausdrehwinkel zwischen Drehgestell und Fahrzeugaufbau abhängige Einstellungen der Radsätze 2 erreicht werden. Dazu genügt beispiels- weise das Verbinden der Querstange 3c des Lenkgestänges 3 mit einem Hebel am fahrzeugseitigen Drehzapfen.By slightly modifying the arrangement shown in FIG. 1, settings of the wheel sets 2 dependent on the angle of rotation between the bogie and the vehicle body can be achieved. For this purpose, it is sufficient, for example, to connect the cross bar 3c of the steering linkage 3 with a lever on the vehicle-side pivot.
Es versteht sich, daß das beschriebene Drehgestell als Triebdrehgestell mit zumindest einem Fahrmotor und zugehörigen Getriebemitteln oder aber als nicht ange¬ triebenes Laufdrehgestell ausgeführt werden kann. Liste der BezuσszeichenIt goes without saying that the bogie described can be designed as a powered bogie with at least one traction motor and associated gear means or as a non-driven bogie.
