Die durch Tatzlagermotoren oder Gestellmotoren (dargestellt: Gestellmotoren) 17 bis 19 angetriebenen Laufrädern sind mit 20 bezeichnet.The by Tatzlagermotoren or rack motors (shown: Frame motors) 17 to 19 driven impellers are designated by 20.

Zur Steuerung des Laufwerks bei Kurvenfahrt sind vier Winkelhebel Winkelhebel 34, 35, 36, 37 mit jeweils rahmenfester Drehachse 38 (Vertikalachse) vorgesehen. Jeweils der erste Arm eines jeden Winkelhebels 34 bis 37 ist über ein Gelenk 39 mit einer Deichsel 40, 41 verbunden. Jeweils der zweite Arm eines jeden Winkelhebels ist über ein Gelenk 44 mit einer Lenkerstange 45, 46, 47, 48 verbunden, wobei die weiteren Enden dieser Lenkerstangen jeweils mittels Gelenke 49 an den Radsatzlagergehäusen 8, 9, 12, 13 der Außenradsätze 14, 16 befestigt sind.There are four angle levers to control the drive when cornering Angle levers 34, 35, 36, 37, each with a more fixed frame Axis of rotation 38 (vertical axis) provided. Each of the first arm of each angle lever 34 to 37 is over a Joint 39 connected to a drawbar 40, 41. Each of the second arm of each angle lever is via a joint 44 connected to a handlebar 45, 46, 47, 48, the further ends of these handlebars each by means of joints 49 on the wheelset bearing housings 8, 9, 12, 13 of the outer wheel sets 14, 16 are attached.

In dieser Art und Weise ist die Deichsel 40 über Winkelhebel 34 und Lenkerstange 45 mit dem Radsatzlagergehäuse 8 sowie über Winkelhebel 35 und Lenkerstange 46 mit dem Radsatzlagergehäuse 9 gekuppelt, während die Deichsel 41 über Winkelhebel 36 und Lenkerstange 47 mit dem Radsatzlagergehäuse 12 sowie über Winkelhebel 37 und Lenkerstange 48 mit dem Radsatzlagergehäuse 13 gekoppelt ist. Die Seitenarme 42 der Deichsel 40, 41 greifen in Gelenke 43 der Radsatzlagergehäuse 10, 11 ein.In this way, the drawbar 40 is via angled lever 34 and handlebar 45 with the wheelset bearing housing 8 as well as angle lever 35 and handlebar 46 with the Wheel set bearing housing 9 coupled while the drawbar 41 via angle lever 36 and handlebar 47 with the wheelset bearing housing 12 and via angle lever 37 and handlebar 48 is coupled to the wheelset bearing housing 13. The side arms 42 of the drawbar 40, 41 engage in joints 43 of the Wheelset bearing housing 10, 11 a.

Nachfolgend wird die Funktionsweise des selbstlenkenden dreiachsiges Laufgestells 1 beschrieben. Durch die Konfiguration Radsatzlagergehäuse 8, 9, 12, 13 mit Gelenken 49 - Lenkerstangen 45, 46, 47, 48 - Winkelhebel 34, 35, 36, 37 - Deichseln 40, 41 - Radsatzlagergehäuse 10, 11 mit Gelenken 43 ergibt sich in Verbindung mit den in Fahrtrichtung/entgegengesetzt zur Fahrtrichtung x1, x2 des Schienenfahrzeuges beweglichen Radsatzlagergehäusen 8, 9, 12, 13 der Außenradsätze 14, 16 und den senkrecht zur Fahrtrichtung beweglichen Radsatzlagergehäusen 10, 11 des Mittelradsatzes eine gegenläufige Kopplung der Außenradsätze bei Kurvenfahrt des Fahrzeuges. Bewegt sich beispielsweise das Radsatzlagergehäuse 13 in Richtung x2, so muß sich zwangsläufig das Radsatzlagergehäuse 9 aufgrund der Kopplung Radsatzlagergehäuse 13/Lenkerstange 48/Winkelhebel 37/Deichsel 41/Radsatzlagergehäuse 11/Deichsel 40/Winkelhebel 37/Lenkerstange 46/Radsatzlagergehäuse 9 in Richtung x1 bewegen, da sich gleichzeitig das Radsatzlagergehäuse 11 in Richtung y1 bewegt. Zusätzlich wirkt die Kopplung der anderen Laufgestellseite zwischen Radsatzlagergehäuse 12/Lenkerstange 47/Winkelhebel 36/Deichsel 41/Radsatzlagergehäuse 10/Deichsel 40/Winkelhebel 34/Lenkerstange 45/Radsatzlagergehäuse 8, wodurch sich Radsatzlagergehäuse 12 in Richtung x1, Radsatzlagergehäuse 8 in Richtung x2 und Radsatzlagergehäuse 10 in Richtung y1 bewegen.Below is how the self-steering works triaxial bogie 1 described. By configuration Wheelset bearing housing 8, 9, 12, 13 with joints 49 - Handlebars 45, 46, 47, 48 - angle levers 34, 35, 36, 37 - Drawbars 40, 41 - wheelset bearing housings 10, 11 with joints 43 arises in connection with the direction of travel / opposite to the direction of travel x1, x2 of the rail vehicle movable wheelset bearing housings 8, 9, 12, 13 of Outer gear sets 14, 16 and perpendicular to the direction of travel movable wheelset bearing housings 10, 11 of the center wheel set an opposite coupling of the outer wheel sets when cornering of the vehicle. For example, the wheelset bearing housing moves 13 in the direction of x2, it must inevitably the wheelset bearing housing 9 due to the coupling of the wheelset bearing housing 13 / handlebar 48 / angle lever 37 / drawbar 41 / axlebox bearing housing 11 / drawbar 40 / angle lever 37 / handlebar 46 / move wheelset bearing housing 9 in direction x1, since at the same time the wheelset bearing housing 11 in the direction y1 moves. In addition, the coupling of the other side of the bogie works between wheelset bearing housing 12 / handlebar 47 / angle lever 36 / drawbar 41 / wheelset bearing housing 10 / drawbar 40 / angle lever 34 / handlebar 45 / wheelset bearing housing 8, whereby wheelset bearing housing 12 in the direction x1, wheelset bearing housing 8 in the direction of x2 and axlebox bearing housing 10 in direction y1.

Bei der vorstehend beschriebenen Ausführungsform ist vorteilhaft auch der Mittelradsatz an dem Steuerungssystem beteiligt, d.h. bei Kurvenfahrt bewegen sich die mittleren Radsatzlager nach bogenaußen (Querverschiebung). Bei Fliehkraftüberschuß im Bogen wirkt die Fliehkraft des mittleren Radsatzes als zusätzliche Steuerkraft zur radialen Einstellung der Außenradsätze. Dies hilft, die der Steuerbewegung entgegenstehenden horizontalen Federauslenkkräfte der Radsatzfedern zu überwinden und verbessert insbesondere bei kleinen Bogenradien die Radsatzstellung zur Bogenmitte.In the embodiment described above is advantageous the center wheel set also participates in the control system, i.e. the middle moves when cornering Wheelset bearings to the outside of the arch (transverse displacement). With excess centrifugal force the centrifugal force of the middle acts in the arch Wheelset as an additional control force for radial adjustment the outer wheel sets. This helps the tax movement opposing horizontal spring deflection forces of the wheelset springs to overcome and improve especially at small radii of radii the wheelset position to the center of the arc.

Im vorstehend erläuterten Ausführungsbeispiel wird von einem angetriebenen dreiachsigen Laufgestell für eine Lokomotive ausgegangen. Das Laufgestell ist jedoch selbstverständlich auch bei nicht angetriebenem Mittelradsatz oder bei nicht angetriebenen Radsätzen einsetzbar.In the exemplary embodiment explained above, a powered three-axle bogie for a locomotive went out. However, the bogie is a matter of course even if the center gear set is not driven or can be used with non-driven wheel sets.
