Ein Drehgestell mit den zuvor genannten Merkmalen ist durch die DE 34 24 531 A1 bekannt, siehe Fig. 4 und 5. Bei diesem Drehgestell sind die nach Art eines hängenden Pendels an jeweiligen Drehachsen des Rahmens 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 features mentioned above is known from DE 34 24 531 A1, see FIGS. 4 and 5. With this bogie they are like a hanging one Pendulum held on respective axes of rotation of the frame Wheelset bearings through a so-called wattage linkage (see in particular Fig. 2) coupled radially adjustable. To stabilize the wheelsets are additional, diagonal mutually extending links (FIG. 13) are provided, which because of the high construction costs as disadvantageous be considered.
Durch die EP-A-0 382 566 gehört ferner ein Drehgestell für Schienenfahrzeuge zum Stand der Technik, dessen Radsätze jeweils Lenkbewegungen um eine senkrechte Achse eines zentralen Lagerkastens ausführen können (siehe Fig. 1). Die Lagerkästen sind an den Enden von V-förmig angeordneten Lenkern gehalten, die andererseits mit Querträgern des Drehgestellrahmens verbunden sind. Um bei Lenkbewegungen der Radsätze um ihre zentrale senkrechte Achse Verschiebungen der Radsatzlager sowohl in Längsrichtung als auch in Querrichtung zu vermeiden, wirken am Drehgestellrahmen befestigte Blattfedern, die zusätzlich gleitfähige Kontaktstreifen aufweisen, mit Gleitflächen auf der Oberseite der Radsatzlager zusammen (siehe Fig. 6). Diese Blattfedern nehmen an den senkrechten Federbewegungen der Radsatzlager teil.A bogie also belongs to EP-A-0 382 566 for rail vehicles of the prior art, the Wheel sets each have steering movements about a vertical axis a central storage box (see Fig. 1). The storage boxes are V-shaped at the ends arranged handlebars held on the other hand with Cross members of the bogie frame are connected. To at Steering movements of the wheel sets around their central vertical Axis displacements of the wheelset bearings both in the longitudinal direction to avoid as well as in the transverse direction act on Bogie frame attached leaf springs, the additional have slidable contact strips with sliding surfaces together on the top of the wheelset bearings (see Fig. 6). These leaf springs take part in the vertical spring movements the wheelset bearing part.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Radsatzlager jeweils durch einen die oberhalb der horizontalen Mittenebene liegende Drehachse aufweisenden Blattlenker am Drehgestellrahmen in Längs- und Querrichtung geführt sind, wobei jeder Blattlenker in an sich bekannter Weise federnd gestaltet und parallel zu den Federn wirksam ist.This object is achieved in that the wheelset bearings each by one above the horizontal center plane having axis of rotation Leaf link on the bogie frame in the longitudinal and transverse directions are guided, with each leaf handle in itself known designed resilient and parallel to the Feathers is effective.
Durch die federnd gestalteten, in die Primärfederung des Drehgestells integrierten Blattlenker mit Drehachse werden alle Querkräfte 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 der 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. By the resiliently designed, in the primary suspension of the Bogie integrated leaf guide with pivot axis all lateral forces between the wheelsets and the Transfer bogie frame, d. that is, the leaf guide also take over the lateral guidance of the wheel sets. In straight The track links result in cooperation with the Steering linkage also a rigid frame side Connection of the wheel sets in the longitudinal direction, for the Axis parallelism is important. With regard to driving The leaf link connections of the Wheelset bearings as fulcrums, the radial settings of the wheel sets due to the balance of forces between the wheels and allow rail in relation to the track arch.
Um den Einfluß von Spiel in den Gelenken des Lenkgestänges auf die Radialeinstellungen der Radsätze möglichst gering zu halten, ist nach einer Ausgestaltung der Erfindung vorgesehen, daß der Blattlenker und das Lenkgestänge in bezug auf die horizontale Mittenebene derart asymetrisch mit dem jeweiligen Radsatzlager verbunden sind, daß der lenkerseitige Hebelarm kleiner ist als der gestängeseitige Hebelarm.To the influence of play in the joints of the steering linkage on the radial settings of the wheel sets if possible According to one embodiment, keeping it low is the Invention provided that the leaf link and the steering linkage with respect to the horizontal center plane like this connected asymmetrically to the respective axlebox bearing are that the handlebar lever arm is smaller than that 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 die Drehachse bildende Gummi-Metall-Buchse am Radsatzlager angeschlossen ist.With regard to wear-free swiveling movements of the Wheelset bearing around the pivot point on the leaf link Another embodiment of the invention is that the leaf guide by a forming the axis of rotation Rubber-metal socket is connected to the wheelset bearing.
Gemäß einer nächsten Ausgestaltung der Erfindung können exakte Maßverhältnisse auf montagefreundliche Weise dadurch erreicht werden, daß der Blattlenker in Längsrichtung einstellbar mit dem Drehgestellrahmen verbunden ist, vorzugsweise über korrespondierende Zahnleisten.According to a next embodiment of the invention exact dimensions in an assembly-friendly manner can be achieved in that the leaf link in the longitudinal direction adjustable connected to the bogie frame is, preferably via corresponding toothed racks.

Das Drehgestell hat zwei Radsätze 2 mit zugehörigen Radsatzlagern
4, wobei zwischen diesen Lagern 4 und dem
Drehgestellrahmen 1 als Primärfedern dienende Federn 5
angeordnet sind. An jedem Radsatzlager 4 greift oberhalb
der horizontalen Mittenebene M unter Einschaltung einer
eine Drehachse 7 bildenden Gummi-Metall-Buchse ein
Blattlenker 6 an, der andererseits am Drehgestellrahmen 1
eingespannt ist. Im Bereich dieser Einspannstelle ausgebildete
korrespondierende Zahnleisten 1a und 6a ermöglichen
auf einfache Weise das maßgenaue Einstellen der
Radsätze 2. Durch die Blattlenker 6 werden die Radsatzlager
4 in Längs- und Querrichtung am Drehgestellrahmen 1
geführt. Die Blattlenker 6 sind federnd gestaltet und
zusammen mit ihrer Gummi-Metall-Buchse als Drehachse 7 in
allen Richtungen parallel zu den Federn 5 wirksam; sie
sind also Bestandteil der Primärfederung.The bogie has two
Unterhalb der horizontalen Mittenebene M der Radsatzlager
4 ist ein Lenkgestänge 3 angeschlossen, das aus Lenkstangen
3a, am Drehgestellrahmen 1 gelagerten Umlenkhebeln
3b und einer die Umlenkhebel 3b verbindenden Querstange
3c besteht. Zwischen der Querstange 3c des Lenkgestänges
3 und dem Drehgestellrahmen 1 ist ein Querdämpfer
8 angeordnet. Das gesamte Lenkgestänge 3 liegt in
der Horizontalen, so daß die Einbauhöhe im Drehgestell
sehr gering ist. Das Lenkgestänge 3 ermöglicht in Gleisbogen
das gegenläufige Verdrehen der beiden Radsätze 2 um
ihre mittlere Hochachse H im Sinne radialer Einstellungen.
Dabei schwenken die Radsatzlager 4 um die durch
die Gummi-Metall-Buchse der Blattlenker 6 gebildete
Drehachse 7. Wie aus Fig. 2 ersichtlich, sind die Blattlenker
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
