Description
Die Erfindung bezieht sich auf ein Fahrzeug, insbesondere Schienenfahrzeug, mit mindestens einem Drehgestell, das einen darüber befindlichen Wagenkasten abstützt und zumindest zwei Spurführungseinheiten, insbesondere mindestens zwei Radsätze, aufweist.The invention relates to a vehicle, in particular rail vehicle, with at least one bogie, which supports a car body located above and at least two tracking units, in particular at least two wheelsets having.
Ein solches Fahrzeug ist z.B. von der
Werden Drehgestelle mit Traktionsmotoren und Stromrichtern ausgestattet, so besteht das Problem, dass sich die auf das Drehgestell einwirkenden mechanischen Belastungen bzw. Kräfte, insbesondere Schwingungen oder ruckartige Bewegungen, unmittelbar auf den Stromrichter übertragen und diesen mechanisch stark belasten können. Die Lebensdauer der Stromrichter kann dadurch signifikant reduziert werden, verglichen mit der Lebensdauer von Stromrichtern, die derartigen mechanischen Belastungen nicht ausgesetzt sind.If bogies are equipped with traction motors and power converters, there is the problem that the mechanical loads or forces acting on the bogie, in particular oscillations or jerky movements, can be transmitted directly to the power converter and mechanically load it heavily. The life of the converters can thereby be significantly reduced compared to the life of power converters, which are not exposed to such mechanical loads.
Der Erfindung liegt daher die Aufgabe zugrunde, ein Fahrzeug mit Drehgestell anzugeben, bei dem Stromrichter möglichst nur geringen mechanischen Belastungen ausgesetzt werden.The invention is therefore based on the object to provide a vehicle with a bogie, are subjected to the power converter as possible only low mechanical loads.
Diese Aufgabe wird erfindungsgemäß durch ein Fahrzeug mit den Merkmalen gemäß Patentanspruch 1 gelöst.This object is achieved by a vehicle with the features according to claim 1.
Danach ist erfindungsgemäß vorgesehen, dass ein Stromrichter mittels zumindest eines Pendels mittelbar oder unmittelbar von dem Wagenkastenboden des darüber befindlichen Wagenkastens pendelfähig gehalten wird und mindestens ein Lenker den Drehgestellrahmen mit dem Stromrichter mechanisch koppelt. Ein wesentlicher Vorteil der Erfindung ist darin zu sehen, dass der Stromrichter aufgrund seiner Pendelanbindung an den Wagenkastenboden pendelfähig ist und somit mechanische Belastungen, die auf den Drehgestellrahmen wirken, wie beispielsweise ruckartige Beschleunigungen, nicht oder zumindest nur in reduziertem Umfang auf den Stromrichter übertragen werden; die Lebensdauer des Stromrichters wird durch diese Maßnahme deutlich vergrößert, verglichen mit einer unmittelbaren Montage an oder auf dem Drehgestell.Thereafter, the invention provides that a power converter is held by means of at least one pendulum pendulum indirectly or directly from the body floor of the car body above it and at least one arm mechanically couples the bogie frame with the power converter. A significant advantage of the invention is the fact that the converter is pendulum because of its pendulum connection to the car body floor and thus mechanical loads that act on the bogie frame, such as jerky accelerations, not or at least only be transferred to the power converter on a reduced scale; the life of the converter is significantly increased by this measure, compared with an immediate mounting on or on the bogie.
Ein weiterer wesentlicher Vorteil des erfindungsgemäßen Fahrzeugs besteht darin, dass durch die Lenkeranbindung des Stromrichters an den Drehgestellrahmen gewährleistet wird, dass der Stromrichter nicht beliebig pendeln kann und - beispielsweise bei Kurvenfahrten - das Drehgestell seine Relativdrehung dem Stromrichter aufzwingen kann. Der Platzbedarf des Stromrichters, insbesondere der nötige Freiraum innerhalb des Drehgestellrahmens, kann durch das aufgezwungene Mitbewegen des Stromrichters somit trotz der Pendelmöglichkeit minimal gehalten werden.Another essential advantage of the vehicle according to the invention is that is ensured by the link connection of the power converter to the bogie frame that the power converter can not commute arbitrarily and - for example when cornering - the bogie can impose its relative rotation to the converter. The space requirement of the power converter, in particular the necessary space within the bogie frame, can thus be minimized by the imposed co-moving the power converter despite the possibility of commuting.

Die Funktion des Lenkers 400 besteht darin, dem Stromrichter 120 die Bewegung des Drehgestellrahmens 11 in Fahrzeugquerrichtung Y aufzuzwingen, wenn es zu einer Relativdrehung zwischen dem Drehgestellrahmen 11 und dem darüber befindlichen Wagenkasten 6 bei einer Kurvenfahrt kommt. Durch das Mitbewegen des Stromrichters 120 ist es möglich, einen kleineren Freiraum 11a für den Stromrichter 120 vorzusehen als dies ohne Mitbewegen möglich wäre.The function of the
Um zu gewährleisten, dass bei Vorwärts- und Rückwärtsfahrt die Arbeitsweise des Lenkers 400 identisch oder zumindest ähnlich ist, wird es als vorteilhaft angesehen, wenn die erste Lenkstange 401 und die zweite Lenkstange 402 gleich lang sind. Mit anderen Worten wird es als vorteilhaft angesehen, wenn von oben in der Draufsicht betrachtet - bei Geradeausfahrt des Schienenfahrzeugs 1 oder bei Geradeausfahrtstellung der Spurführungseinheiten - die erste Lenkstange 401 und die zweite Lenkstange 402 und die fiktive Verbindungslinie zwischen den zwei stromrichterseitigen Gelenken 421 und 422 ein gleichschenkliges Dreieck bilden. Die fiktive Verbindungslinie der zwei stromrichterseitigen Gelenken 421 und 422 ist bevorzugt horizontal (± 10 Grad) angeordnet.In order to ensure that the operation of the
