Solche Wankstabilisatoren sind in verschiedenen hydraulisch oder rein mechanisch wirkenden Ausführungen bekannt.

Die Torsionswelle wird demgemäß mit einem Torsionsmoment beaufschlagt, welches sie - je nach ihrer Torsionssteifigkeit - bei einem bestimmten Torsionswinkel durch ein aus ihrer elastischen Verformung resultierendes Gegenmoment ausgleicht und so eine weitere Wankbewegung verhindert. Dabei kann bei mit Drehgestellen ausgestatteten Schienenfahrzeugen die Wankstützeinrichtung sowohl für die Sekundärfederstufe vorgesehen sein, d. h. zwischen einem Fahrwerksrahmen und dem Wagenkasten wirken. Ebenso kann die Wankstützeinrichtung auch in der Primärstufe eingesetzt werden, d. h. zwischen den Radeinheiten und einem sitting lever. The torsion wave is thus subjected to a torsional moment which, depending on its torsional stiffness, is compensated for at a certain torsion angle by a counter-torque resulting from its elastic deformation and thus a further rolling motion prevented. It can be provided for both the secondary spring stage in bogie-equipped rail vehicles, the anti-roll device, ie act between a chassis frame and the car body.

Dabei ist vorgesehen, dass sich die gedachten Verlängerungen der beiden Zug-Druckstangen in zumindest einem Beladezustand des Fahrzeuges - idealerweise - in einem Punkt schneiden, der - genau oder näherungsweise - auf der Drehachse der  Roll stabilizer solved with the features of claim 1. Advantageous embodiments of the invention are defined in the respective dependent claims. It is envisaged that the imaginary extensions of the two train push rods in at least one loading state of the vehicle - ideally - intersect at a point that - exactly or approximately - on the axis of rotation of the
Ausdrehbewegung des Fahrwerkes liegt. Üblicherweise liegt diese Drehachse im geometrischen Zentrum des Fahrwerkes. Boring movement of the chassis is. Usually, this axis of rotation lies in the geometric center of the chassis.
Normalerweise sind die Zug-Druckstangen gleich weit von diesem Punkt entfernt. Meist ist der eine Fahrzeugteil, mit dem der Wankstabilisator in Verbindung steht, das Fahrwerk, und der andere Normally the pull push rods are equidistant from this point. Most of the vehicle part with which the roll stabilizer is connected is the landing gear and the other

Die Zug-Druckstangen des Wanksstabilisators schließen bei der vorliegenden Erfindung in der Regel nicht nur bezüglich einer Querebene, welche normal zur Fahrzeuglängsachse verläuft (der y-z-Ebene gemäß voriger Definition) einen Winkel mit derIn the present invention, the train-pressure bars of the Wankstabilisators usually not at an angle with respect to a transverse plane which is normal to the vehicle longitudinal axis (the y-z plane as defined above)

Es hat sich gezeigt, dass bei erfindungsgemäßer Anordnung der Zug-Druckstangen eine Reduktion der maximalen dynamischen Kräfte in den Zug-Druckstangen auf das Niveau von Zug- Druckstangen bei herkömmlicher vertikaler Anordnung möglich ist, wenn die maximalen Kräfte aus Szenarien resultieren, die eine Ausdrehung des Fahrwerkes beinhalten. Die Zug- Druckstangen und deren Gelenke erreichen dadurch eine höhere Lebensdauer und müssen eventuell weniger oft ausgetauscht werden . It has been found that with inventive arrangement of the train push rods, a reduction of the maximum dynamic forces in the train push rods to the level of train push rods in conventional vertical arrangement is possible if the maximum forces resulting from scenarios that a rotation of the Suspension include. The pull push rods and their joints thus achieve a longer life and may need to be replaced less often.
Die erfindungsmäßige Anordnung ist unabhängig davon, ob die Torsionswelle am Fahrwerk oder am Wagenkasten gelagert ist, ob die Zug-Druck Stangen nach oben oder nach unten zeigen, und ob der Schnittpunkt der gedachten Verlängerung der Zug- Druck Stangen unterhalb oder oberhalb des Wanksystems liegt. Die erfindungsmäßige Anordnung ist nicht auf ein Wanksystem beschränkt. Es können mehrere Wanksysteme, also mehrere Wankstabilisatoren, pro Fahrwerk vorliegen, wobei alle The arrangement according to the invention is independent of whether the torsion is mounted on the chassis or on the car body, whether the train-pressure rods show up or down, and whether the intersection of the imaginary extension of the train-pressure rods is below or above the roll system. The inventive arrangement is not limited to a roll system. It can be several roll systems, so several Roll stabilizers, are available per chassis, with all
Wankstabilisatoren eines Fahrwerkes an einem Wagenkasten, oder aber auch an getrennten Wagenkästen angeordnet sein können. Die gedachten Verlängerungen der Zug-Druckstangen verschiedener Wankstabilisatoren haben dabei möglicher Weise keinen gemeinsamen wie oben definierten Schnittpunkt mit der Drehachse der Ausdrehbewegung des Fahrwerks. Roll stabilizers of a chassis on a car body, or can also be arranged on separate car bodies. The imaginary extensions of the train-push rods of various roll stabilizers may not have a common as defined above intersection with the axis of rotation of the Ausdrehbewegung of the chassis.
Bei einer möglichen Anwendungsform der Erfindung sind pro Fahrwerk zumindest zwei Wankstabilisatoren vorgesehen (es könnten aber auch mehrere Paare von Wankstabilisatoren vorgesehen sein) , deren Torsionswellen parallel angeordnet sind und wo die gedachten Verlängerungen aller Zug- Druckstangen sich in zumindest einem Beladezustand des In one possible embodiment of the invention per chassis at least two roll stabilizers are provided (but it could also be provided several pairs of roll stabilizers), the torsion waves are arranged in parallel and where the imaginary extensions of all train push rods in at least one loading condition of
Fahrzeuges in einem Punkt schneiden, der näherungsweise auf der Drehachse der Ausdrehbewegung des Fahrwerkes liegt. Die Zug-Druckstangen sind somit spiegelsymmetrisch bezüglich der eingangs definierten y-z-Ebene und x-z-Ebene angeordnet. Es liegen somit alle vier Zug-Druckstangen auf einem allen Zug- Druckstangen gemeinsamen Kegelmantel, wobei die Höhenachse des Kegels mit der Drehachse der Ausdrehbewegung des Vehicle at a point that is approximately on the axis of rotation of the Ausdrehbewegung the chassis. The pull-push rods are thus arranged mirror-symmetrically with respect to the initially defined y-z plane and x-z plane. There are thus all four train push rods on a common all Zug push rods cone sheath, wherein the height axis of the cone with the axis of rotation of the Ausdrehbewegung of the
Fahrwerks zusammenfällt. Suspension collapses.
Die erfindungsgemäße Anordnung der Zug-Druckstangen ist in der Praxis, beim Betrieb des Schienenfahrzeugs, normalerweise nur bei einer bestimmten Belastung des Schienenfahrzeugs gegeben. Denn je nach Beladung kommt es zu einer The arrangement of the train push rods according to the invention is given in practice, during operation of the rail vehicle, usually only at a certain load on the rail vehicle.

Da die größten Kräfte in den Zug-Druckstangen üblicherweise bei voller Beladung auftreten, bietet sich dieser Zustand für die erfindungsgemäße geometrische Anordnung der Zug-Druckstangen an. Es könnte aber genauso ein anderer Zustand, etwa der leere Zustand des Wagenkastens gewählt werden, wo die Zug- Druckstangen die erfindungsgemäße Position einnehmen. Die Schrägstellung der Zug-Druckstangen, also deren Neigung gegenüber der Drehachse der Ausdrehbewegung, wird in der Regel zwischen 2° und 10° liegen. Wird also eine Zug- Druckstange in die y-z-Ebene und/oder x-z-Ebene projiziert, so schließt sie mit der z-Richtung einen Winkel zwischen 2° und 10° ein. different inclination of the train push rods. Since the largest forces in the train push rods usually occur at full load, this state offers itself for the inventive geometric arrangement of the train push rods. But it could just as another state, such as the empty state of the car body are selected, where the train push rods occupy the position of the invention. The inclination of the train push rods, so their inclination relative to the axis of rotation of the Ausdrehbewegung, will usually be between 2 ° and 10 °. Thus, if a pull-push rod is projected into the yz-plane and / or xz-plane, it encloses an angle between 2 ° and 10 ° with the z-direction.
Die erfindungsmäßige Anordnung der Zug-Druckstangen erfüllt ihren Zweck auch, wenn die Anordnung von der beschrieben Idealanordnung geringfügig abweicht, d.h. wenn sich die gedachten Verlängerungen der Zug-Druckstangen eines The arrangement of the train push rods according to the invention also serves its purpose if the arrangement differs slightly from the described ideal arrangement, i. when the imaginary extensions of the train push rods of a

In Fig. 1 sind zwei erfindungsgemäße Wankstabilisatoren dargestellt, die in einem Schienenfahrzeug eingebaut sind. Zur besseren Beschreibung der Erfindung sind die übrigen Teile des Schienenfahrzeugs nicht dargestellt. In Fig. 1, two roll stabilizers according to the invention are shown, which are installed in a rail vehicle. For a better description of the invention, the remaining parts of the rail vehicle are not shown.
Jeder Wankstabilisator weist eine Torsionswelle 1 auf, an deren Enden jeweils ein Hebel 2 angeordnet ist. In einem rechtwinkeligen Koordinatensystem mit einer x-Achse parallel zur Fahrzeuglängsachse, mit einer y-Achse in Querrichtung des Fahrzeugs und einer z-Achse in Vertikalrichtung des Fahrzeugs ist die Torsionswelle 1 parallel zur y-Achse angeordnet, währen die Hebel 2 parallel zur x-Achse liegen. Each roll stabilizer has a torsion shaft 1, at the ends of which a lever 2 is arranged in each case. In a rectangular coordinate system with an x-axis parallel to the vehicle longitudinal axis, with a y-axis in the transverse direction of the vehicle and a z-axis in the vertical direction of the vehicle, the torsion shaft 1 is arranged parallel to the y-axis, while the lever 2 parallel to x Axis lie.
Die vier Zug-Druckstangen 3 sind mittels je eines The four train push rods 3 are each by means of one
Kugelgelenks 4 an einem Ende gelenkig mit dem freien Ende des Hebels 2 verbunden. Am anderen Ende sind die Zug-Druckstangen 3 jeweils über ein weiteres Kugelgelenk 8 mit dem nicht dargestellten Wagenkasten oder dem Fahrwerk verbunden. DieBall joint 4 at one end hingedly connected to the free end of the lever 2. At the other end of the train push rods 3 are each connected via another ball joint 8 with the car body or the chassis, not shown. The
Zug-Druckstangen 3 schließen sowohl in y-Richtung als auch in x-Richtung einen Winkel mit der z-Richtung ein, indem ihr - hier oberes - Ende vom Hebel 2 weg geneigt ist. Wenn die z- Achse des rechtwinkeligen Koordinatensystems so festgelegt ist, dass sie die Fahrzeuglängsachse genau in der Mitte zwischen den beiden Torsionswellen 1 schneidet, dann muss die Neigung der Zug-Druckstangen 3 erfindungsgemäß so eingestellt sein, dass sich die strichliert dargestellten Verlängerungen der vier Zug-Druckstangen 3 - hier im Fall der Fig. 1 unter den Wankstabilisatoren - in einem gemeinsamen Punkt auf der z-Achse schneiden. Die Zug-Druckstangen 3 liegen aufgrund der bezüglich der y-z-Ebene und x-z-Ebene spiegelsymmetrischen Anordnung somit auf dem Mantel eines geraden Kreiskegels, der also eine kreisförmige Grundfläche und eine darauf normal stehende Achse aufweist. Die Achse des Kreiskegels liegt auf der z-Achse, seine Spitze unter den Zug-Druckstangen 3. Es wäre auch möglich, dass bei gleicher Anordnung der Tensile push rods 3 include an angle with the z-direction in both the y-direction and in the x-direction, in that - here upper end - it is inclined away from the lever 2. If the z-axis of the rectangular coordinate system is set so that it intersects the vehicle longitudinal axis exactly midway between the two torsional shafts 1, then the inclination of the train push rods 3 according to the invention must be set so that the dashed represent extensions of the four train -Print rods 3 - here in the case of Fig. 1 under the roll stabilizers - cut in a common point on the z-axis. Due to the mirror-symmetrical arrangement with respect to the yz-plane and xz-plane, the pull-push rods 3 thus rest on the mantle of a straight circular cone, which thus has a circular base surface and an axis normal thereon. The axis of the circular cone lies on the z-axis, its tip under the push-push rods 3rd It would also be possible that with the same arrangement of
Torsionswellen 1 und der Hebel 2 die Zug-Druckstangen 3 an ihren vom Hebel 2 abgewandten Enden zur z-Achse hin geneigt sind, sodass sich die Spitze des Kreiskegels oberhalb der Wankstabilisatoren befindet. Torsionswellen 1 and the lever 2, the train push rods 3 are inclined at their ends facing away from the lever 2 to the z-axis, so that the tip of the circular cone is above the roll stabilizers.
In den Fig. 2-4 ist ein Fahrwerk 6 mit erfindungsgemäßen Wankstabilisatoren gemäß Fig. 1 dargestellt. Das Fahrwerk 6 umfasst unter anderem die Lager für die Räder 9. Die In FIGS. 2-4, a chassis 6 with roll stabilizers according to the invention according to FIG. 1 is shown. The chassis 6 includes, inter alia, the bearings for the wheels 9. The
Torsionswellen 1 sind am Wagenkasten 7 befestigt, sie Torsionswellen 1 are attached to the car body 7, they
verlaufen in Fahrzeugquerrichtung (parallel zur y-Achse) . Die beiden Wankstabilisatoren sind bezüglich der y-z-Ebene spiegelbildlich angeordnet, jeder Wankstabilisator ist zusätzlich spiegelbildlich bezüglich der x-z-Ebene run in the vehicle transverse direction (parallel to the y-axis). The two roll stabilizers are arranged in mirror image with respect to the y-z plane, and each roll stabilizer is additionally mirror-inverted with respect to the x-z plane
ausgebildet. Die Wankstabilisatoren sind mit dem Fahrwerk 6 einerseits und mit dem Wagenkasten 7 andererseits verbunden. educated. The roll stabilizers are connected to the chassis 6 on the one hand and to the car body 7 on the other.
In Fig. 3 ist die Draufsicht auf die Wankstabilisatoren aus Fig. 1 entlang der z-Achse dargestellt. Die z-Achse ist hier der Punkt, in dem sich die strichliert dargestellte x-Achse mit der y-Achse schneidet. Die z-Achse entspricht der FIG. 3 shows the plan view of the roll stabilizers from FIG. 1 along the z-axis. Here, the z-axis is the point where the dashed x-axis intersects with the y-axis. The z-axis corresponds to the
Drehachse der Ausdrehbewegung des Fahrwerks 6. Rotary axis of the boring movement of the chassis 6.
Das Fahrwerk der Fig. 2-4 könnte aber auch weitere The chassis of Fig. 2-4 could also be more
Wankstabilisatoren zwischen Fahrwerk 6 und Wagenkasten 7 aufweisen. Die gedachten Verlängerungen der beiden Zug- Druckstangen eines weiteren Wankstabilisators könnten sich dann in einem anderen Punkt der Drehachse schneiden als jene der beiden dargestellten Wankstabilisatoren. Roll stabilizers between chassis 6 and car body 7 have. The imaginary extensions of the two train push rods of another roll stabilizer could then intersect at a different point on the axis of rotation than those of the two roll stabilizers shown.
Selbstverständlich können zur Ausführung der Erfindung auch andere Gelenke als Kugelgelenke zur Anwendung kommen. Die Kugelgelenke 8 bzw. andere Gelenke am Ende 5 der Zug- Druckstangen 3 können auch über andere Vorrichtungen, wie Feder- oder Dämpfereinrichtungen am Wagenkasten angreifen.
