Abstract

The bogie has a frame (8) with an axle at each end. Each axle is supported in bearings (2) mounted on springs (7) so that each bearing has a limited degree of longitudinal movement w.r.t the frame. Each bearing (2) is connected by a pivoted link (5) to one end of a central link (9) which is pivoted to the frame. The linkages are so arranged that the two bearings on the same side of the frame either move simultaneously towards each other or away from each other.

Description

Die Erfindung bezieht sich auf ein Drehgestell mit gelenkten Radsätzen, bei dem die Radsätze durch Lenker untereinander radial einstellbar geführt sind.The invention relates to a bogie with steered wheelsets, in which the wheelsets are guided radially adjustable by the handlebars.

Durch die DE-B-16 05 826 ist ein Drehgestell bekannt, bei dem die Radsätze durch zwei an diametral gelegenen Radsatzlagern angreifende Lenker radial einstellbar geführt sind. Die an den Radsatzlagern angeschlossenen Lenker sind in Drehgestellmitte über einen Hebel drehfest mit einer Welle verbunden, die in einem Drehgestellrahmen quer zur Fahrtrichtung liegend drehbar gelagert ist. Die beiden Hebel sind um 180° zueinander versetzt, so daß sich beim Durchfahren eines Gleisbogens nach dem Anlaufen des vorderen Radsatzes und dessen radiale Einstellung auf dem Krümmungsmittelpunkt des Gleisbogens über die Lenker auch der nachfolgende Radsatz radial auf den Krümmungsmittelpunkt hin einstellen kann. Eine solche Lenkeinrichtung hat den entscheidenden Nachteil, daß über den Lenkmechanismus keine Übertragung von Zug- und Stoßkräften vom vorderen auf den hinteren Radsatz möglich ist.From DE-B-16 05 826 a bogie is known in which the wheel sets are guided in a radially adjustable manner by two links acting on diametrically located wheel set bearings. The handlebars connected to the wheelset bearings are non-rotatably connected to a shaft in the center of the bogie with a shaft, which is rotatably mounted in a bogie frame lying transverse to the direction of travel. The two levers are offset by 180 ° to each other, so that when driving through a curve after starting the front wheel set and its radial adjustment on the center of curvature of the curve via the handlebars, the following wheel set can also adjust radially towards the center of curvature. Such a steering device has the decisive disadvantage that no transmission of tensile and impact forces from the front to the rear wheelset is possible via the steering mechanism.

Hier setzt die Erfindung ein, deren Aufgabe darin besteht, einen Lenkmechanismus gemäß dem Gattungsbegriff so weiterzubilden, daß eine Übertragung der Zug- und Stoßkräfte von einem Radsatz auf den anderen möglich ist, ohne daß die radiale Einstellbarkeit der Radsätze darunter beeinträchtigt wird.This is where the invention comes in, the object of which is to further develop a steering mechanism according to the generic term so that transmission of the tensile and impact forces from one wheel set to the other is possible without the radial adjustability of the wheel sets below being impaired.

Diese Aufgabe wird dadurch gelöst, daß jeder Radsatz eines Drehgestelles eine hohle Radsatzwelle aufweist, in der eine Welle koaxial drehbar gelagert ist, daß die Welle an ihren freien Enden drehfest mit einem ersten bzw. zweiten Hebel verbunden ist, wobei die beiden Hebel um 180° versetzt sind, und daß der erste Hebel mit dem ersten Lenker und der zweite Hebel mit dem zweiten Lenker elastisch verbunden ist und beide Lenker in angrenzenden Langträgern eines Drehgestellrahmens in gleicher Entfernung von der Radsatzwelle gelenkig gelagert sind.This object is achieved in that each wheel set of a bogie has a hollow wheel set shaft, in which a shaft is rotatably mounted coaxially, that the shaft is rotatably connected at its free ends to a first or second lever, the two levers by 180 ° are offset, and that the first lever is elastically connected to the first link and the second lever to the second link and both links are articulated in adjacent long girders of a bogie frame at the same distance from the wheelset shaft.

Eine solche Einrichtung ist besonders vorteilhaft beim Einbau eines Monomotors. Dadurch, daß die Welle durch die hohle Radsatzwelle geführt wird, können ungehindert die Getriebemittel zwischen Monomotor und den Radsatzwellen angeordnet werden.Such a device is particularly advantageous when installing a mono motor. Because the shaft is guided through the hollow wheelset shaft, the gear means can be arranged between the monomotor and the wheelset shafts without hindrance.

Zur Lenkung von Radsätzen eines Drehgestelles wird wie in Figur 1 dargestellt, jedes Radsatzlager elastisch an Lenker 3 bis 4 angeschlossen. Die Radsatzlager sind über Primärfedern längs- und querelastisch mit Langträgern 8 eines Drehgestellrahmens verbunden, so daß sich die Radsätze 1 beim Bogenlauf ohne größeren Widerstand in Richtung auf einen Krümmungsmittelpunkt eines Gleisbogens ausrichten können.For steering wheelsets of a bogie, as shown in FIG. 1, each wheelset bearing is connected elastically to handlebars 3 to 4. The wheelset bearings are longitudinally and transversely elastically connected to the long beams 8 of a bogie frame via primary springs, so that the wheelsets 1 can align themselves in the direction of a curve center of a track curve without greater resistance when running on bends.

Erfindungsgemäß ist die Welle 10 in eine hohle Radsatzwelle 16 des Radsatzes 1 einzubauen. Die Welle 10 ist konzentrisch in der Radsatzwelle 16 gelagert und weist an ihren Enden einen ersten und zweiten Hebel 9 und 11 auf, die beide drehfest mit Welle 10 verbunden sind. Der erste Hebel 9 ist über einen ersten Lenker 3 und der zweite Hebel 11 über einen zweiten Lenker 4 mit den Langträgern 8 des Drehgestellrahmens gelenkig verbunden.According to the invention, the shaft 10 is to be installed in a hollow wheel set shaft 16 of the wheel set 1. The shaft 10 is mounted concentrically in the wheelset shaft 16 and has at its ends a first and second lever 9 and 11, both of which are connected to the shaft 10 in a rotationally fixed manner. The first lever 9 is articulated via a first link 3 and the second lever 11 via a second link 4 with the long beams 8 of the bogie frame.

Wie aus Figur 2 zu ersehen ist, sind die Lenker 3 und 4 der Radsatzführung nach Figur 4 gleich lang, die Hebel 9 und 11 sind um 180° versetzt. Jeder Radsatz des Drehgestelles ist in gleicher Weise angelenkt, wie in den Figuren 1 und 2 dargestellt.As can be seen from Figure 2, the links 3 and 4 of the wheelset guide according to Figure 4 are of equal length, the levers 9 and 11 are offset by 180 °. Each wheel set of the bogie is articulated in the same way as shown in Figures 1 and 2.
