Description

Die Erfindung betrifft eine Radsatzsteuerung für Drehgestelle von Schienenfahrzeugen, insbesondere Triebdrehgestelle nach dem Oberbegriff des Patentanspruches 1.The invention relates to a wheel set control for bogies of rail vehicles, in particular engine bogies according to the preamble of claim 1.

Eine Radsatzsteuerung dieser Art ist durch die DE-A 3 827 412 bekanntgeworden. Diese Radsatzsteuerung ist als Kastensteuerung ausgebildet, bei der die beiden Hebel, welche je zwei Radsatzführungshebel einer Drehgestellängsseite verbinden, in ihrer Drehachse einerseits über einen abstehenden Hebel an eine die beiden abstehenden Hebel verbindende Stange und anderseits über zwei aufeinanderfolgende im Winkel zueinander gelenkig verbundene Hebel mit dem Wagenkasten verbunden sind. Durch die Vielzahl der Hebel und Gelenke ist diese Steuerung aufwendig und störanfällig.A wheel set control of this type has become known from DE-A 3 827 412. This wheel set control is designed as a box control, in which the two levers, which connect two wheel set guide levers on one side of the bogie, in their axis of rotation on the one hand via a protruding lever to a rod connecting the two protruding levers and on the other hand via two successive levers articulated at an angle to one another Car body are connected. Due to the large number of levers and joints, this control is complex and prone to failure.

Mit ähnlichem Nachteil ist auch die Konstruktion nach der US-A-4 660 476 behaftet, bei welcher an jeder Drehgestellseite auf einer Drehwelle um 90° zueinander verdrehte Steuerungshebel vorhanden sind. Bei allfälliger Verwendung reiner Zugglieder liegen diese in einer anderen Ebene als die Radsatzführungshebel, wodurch sich verhältnismäßig komplizierte Kraftschlüsse im Koppelmechanismus ergeben.The construction according to US Pat. No. 4,660,476 also has a similar disadvantage, in which control levers are provided on each side of the bogie on a rotating shaft which are rotated by 90 ° with respect to one another. If pure tension members are used, they are in a different plane than the wheel set guide levers, which results in relatively complicated frictional connections in the coupling mechanism.

Aufgabe der Erfindung ist die Schaffung einer Radsatzlängskopplung, die unter Vermeidung der Nachteile der bekannten Konstruktionen vor allem den vorlaufenden Radsatz bei dieser radialen Einstellung unterstützt und eine Längskopplung der Radsätze bewirkt, um diese gegensinnig einzudrehen, wenn das Fahrzeug in einem Gleisbogen fährt, und das Drehgestell gegenüber dem Wagen- bzw. Lokkasten ausdreht.The object of the invention is to provide a wheel set longitudinal coupling which, while avoiding the disadvantages of the known constructions, above all supports the leading wheel set in this radial setting and a Longitudinal coupling of the wheel sets causes them to be turned in opposite directions when the vehicle is traveling on a curved track and the bogie is turned relative to the car or locomotive body.

Zur Lösung dieser Aufgabe dient die Maßnahme nach dem kennzeichnenden Teil des Patentanspruches 1.The measure according to the characterizing part of patent claim 1 serves to solve this problem.

Durch die Maßnahmen nach den Ansprüchen 2 bis 4 vereinfacht sich die erfindungsgemäße Konstruktion gegenüber den bekannten Konstruktionen, da die reinen Zugglieder gewichts- und platzsparend dimensioniert werden können.The measures according to claims 2 to 4 simplify the construction according to the invention compared to the known constructions, since the pure tension members can be dimensioned to save weight and space.

Die Erfindung wird anhand der Zeichnung näher erläutert, in welcher ein Ausführungsbeispiel der gegenständlichen Radsatzsteuerung dargestellt ist.The invention is explained in more detail with reference to the drawing, in which an embodiment of the subject wheel set control is shown.

Die einzige Figur zeigt in vereinfachter Form eine Draufsicht der Radsatzsteuerung.The single figure shows in simplified form a top view of the wheel set control.

Mit 1 ist ein Drehgestellrahmen bezeichnet, in welchem zwei Radsätze 2, 2' mit ihren Achsen 3, 3' und den Rädern 4, 5, 6 und 7 gelagert sind. Zum Antrieb der Räder 4 bis 7 dienen Motore 8, 8' mit ihren Getrieben.1 with a bogie frame is designated, in which two wheel sets 2, 2 'with their axles 3, 3' and the wheels 4, 5, 6 and 7 are mounted. Motors 8, 8 'with their gears serve to drive the wheels 4 to 7.

Jeder der beiden Radsätze 2, 2' bzw. deren Achslagergehäuse ist an der Außenseite der Räder 4 bis 7 bzw. der Achslagergehäuse an je einen Radsatzführungshebel 9, 9A bzw. 10, 10A angeschlossen. Die beiden Radsatzführungshebel 9, 10 bzw. 9A, 10A je zweier in der Fahrtrichtung hintereinander angeordneter Räder 4, 6 bzw. 5, 7 sind an je einen Arm eines doppelarmigen Steuerungshebels 11 bzw. 11A angelenkt, welcher um einen lotrechten Zapfen 12 bzw. 12A im mittigen Querbalken 13 des Drehgestellrahmens 1 schwenkbar gelagert ist.Each of the two wheel sets 2, 2 'or their axle bearing housing is connected to a wheel set guide lever 9, 9A or 10, 10A on the outside of wheels 4 to 7 or the axle bearing housing. The two wheel set guide levers 9, 10 and 9A, 10A each of two wheels 4, 6 and 5, 7 arranged one behind the other in the direction of travel are articulated to one arm of a double-armed control lever 11 or 11A, which is connected to a vertical pin 12 or 12A is pivotally mounted in the central crossbeam 13 of the bogie frame 1.

In der mittigen Lager der Räder 4 bis 7, d.h., bei der Einstellung dieser Räder für die Geradeausfahrt des Drehgestellrahmens, sind die beiden Steuerungshebel 11, 11A schräg, d.h. sie konvergieren zueinander in der einen Fahrtrichtung. Die beiden einander jeweils gegenüberliegenden Arme der Steuerungshebel 11, 11A sind vorzugsweise an der Anlenkstelle der Radsatzführungshebel 9, 9A bzw. 10, 10A durch eine Zugstange 14 bzw. 14' untereinander verbunden. Nach der erfindungsgemäßen Konstruktion wird nur ein Steuerungshebel je Drehgestellseite benötigt, die Elemente 11, 11A, 14, 14', 9, 9A, 10, 10A können in einer Ebene liegen, wodurch sich effektivere und einfachere Kraftflüsse im Koppelmechanismus im Gegensatz zur bekannten Konstruktion nach der US-A-4 660 476 ergeben.In the central bearing of the wheels 4 to 7, that is, when setting these wheels for straight-ahead driving Bogie frame, the two control levers 11, 11A are oblique, that is, they converge to each other in one direction. The two opposite arms of the control levers 11, 11A are preferably connected to one another at the articulation point of the wheel set guide levers 9, 9A or 10, 10A by means of a pull rod 14 or 14 '. According to the construction according to the invention, only one control lever is required per bogie side, the elements 11, 11A, 14, 14 ', 9, 9A, 10, 10A can lie in one plane, which results in more effective and simple power flows in the coupling mechanism in contrast to the known construction U.S. 4,660,476.

Die Radsatzführungshebel 9, 9A bzw. 10, 10A sowie die Zugstangen 14, 14', Hebel od. dgl. müssen eine gewisse Steifigkeit aufweisen, die durch das eingezeichnete Federsymbol angedeutet ist. Diese Hebel, Stangen od. dgl. übertragen einerseits Zugkräfte und anderseits Bremskräfte und haben auch die Aufgabe, Längsschwingungen abzufangen.The wheel set guide levers 9, 9A or 10, 10A as well as the tie rods 14, 14 ', levers or the like must have a certain rigidity, which is indicated by the spring symbol shown. These levers, rods or the like transmit on the one hand tensile forces and on the other hand braking forces and also have the task of absorbing longitudinal vibrations.

Im Rahmen der Erfindung können verschiedene konstruktive Abänderungen vorgenommen werden. So besteht die Möglichkeit, daß die Stangen, Lenker, Hebel od. dgl. 14, 14' die Arme der doppelarmigen Hebel 11, 11A kreuzweise verbinden, oder kreuzweise und wie beschrieben. Wesentlich ist, daß mindestens ein Arm des einen doppelarmigen Hebels 11 mit einem Arm des anderen doppelarmigen Hebels 11A durch eine Stange, einen Lenker, einen Hebel od. dgl. verbunden ist.Various design changes can be made within the scope of the invention. So there is the possibility that the rods, handlebars, levers or the like. 14, 14 'connect the arms of the double-armed levers 11, 11A crosswise, or crosswise and as described. It is essential that at least one arm of one double-armed lever 11 is connected to one arm of the other double-armed lever 11A by a rod, a handlebar, a lever or the like.
