Beschreibung ( Spoiler für Personenzüge ) :Description (spoiler for passenger trains):

Die meisten Wagen der im Schienenverkehr eingesetzten Personenzüge haben Schiebefenster, die von den Reisenden geöffnet werden können. Oft bleiben -gerade in der wärmeren Jahreszeit- die Fenster während der Fahrt geöffnet und verursachen in diesem Zustand Luftströmungen im Fensterbereich, die sich einerseits in den Innenraum ausbreiten und dort als störend empfunden werden (Zugluft), andererseits erhebliche Luftwiderstände und damit Energieverluste darstellen. Auch im geschlossenen Zustand sind häufig Windgeräusche wahrzunehmen, die von Undichtigkeiten der Fenster oder Windrichtungsänderungen herrühren.
Diese Einflüsse mindern den Fahrkomfort. Andererseits sind durch das Verwirbeln der Luft- und das Eindringen der bewegten Luftmassen in den Innenraum höhere Widerstände von der Lok z.u überwinden und dadurch mehr Energie aufzubringen.
Most of the carriages of passenger trains used in rail transport have sliding windows that can be opened by passengers. Often - especially in the warmer seasons - the windows remain open during the journey and in this state cause air currents in the window area, which on the one hand spread into the interior and are perceived as disturbing (drafts), and on the other hand represent considerable air resistance and thus energy losses. Even when the windows are closed, wind noise can often be heard, which is caused by leaks in the windows or changes in wind direction.
These influences reduce driving comfort. On the other hand, the turbulence of the air and the penetration of moving air masses into the interior mean that the locomotive has to overcome greater resistance and therefore needs more energy.

Der im Anspruch 1 angegebenen Erfindung liegt das Problem zugrunde, ein Strömungsleitblech (Spoiler) zu entwickeln, das die störenden Windgerausche und die Zugluft bei geöffnetem Fenster einerseits, und die Energieverluste durch Luftverwirbelungen an dem geöffneten Fenster andererseits vermindert (Fig. 1). Dabei ist dem Umstand Rechnung zu tragen, daß jeder einzelne Wagen je nach vorherigen Rangierarbeiten seine Fahrtrichtung ändern kann, was eine Umkehrung der Strömungsrichtung für den Spoiler bedeutet. Der Spoiler muß sich also den wechselnden Umständen anpassen und entsprechend ausrichten.The invention specified in claim 1 is based on the problem of developing a flow guide plate (spoiler) that reduces the annoying wind noise and drafts when the window is open on the one hand, and the energy losses due to air turbulence at the open window on the other (Fig. 1). In doing so, account must be taken of the fact that each individual car can change its direction of travel depending on previous shunting work, which means a reversal of the flow direction for the spoiler. The spoiler must therefore adapt to the changing circumstances and align itself accordingly.

Er ist daher an dem Gelenkbol'zen (2) "nii'ftels Kugellager drehbar gelagert und somit ausrichtbar.It is therefore mounted on the pivot pin (2) using a ball bearing so that it can rotate and can therefore be aligned.

Im /orderen, angeströmten Eereich des Spoilers (1) wird die Strömung das Leitblech (1) an die Wand andrücken; im hinteren Bereich wird die Strömung aufgrund Unterdruckausbildung dieses Moment um den Gelenkbolzen (2) noch verstärken (Fig. 2).In the front, flow-actuated area of the spoiler (1), the flow will press the guide plate (1) against the wall; in the rear area, the flow will increase this moment around the hinge pin (2) due to the formation of negative pressure (Fig. 2).

Aufgrund dieses strömungstechnischen Phänomens verharrt der Spoiler (1) ohne zusätzliche Haltekräfte in seiner ausgerichteten Position.Due to this fluidic phenomenon, the spoiler (1) remains in its aligned position without additional holding forces.

Unterstützt wird dieser stabile Zustand durch einen Gummibelag (3), der die Haftung zwischen Spoilerkante und Wand erhöht. Die Spoilerkante ist hierbei derart umgeschlagen, daß die abgeknickte Fläche an der Gegenfläche (Waggonwand) plan aufliegt und in einer Vertiefung der Wand versenkt ist, damit die Spoilerkante nicht unterströmt werden kann und keine Auftriebskräfte den Spoiler (.1) anheben können. (Fig. 4).This stable state is supported by a rubber coating (3), which increases the adhesion between the spoiler edge and the wall. The spoiler edge is folded over in such a way that the bent surface lies flat on the opposite surface (wagon wall) and is sunk into a recess in the wall, so that air cannot flow under the spoiler edge and no buoyancy forces can lift the spoiler (.1). (Fig. 4).

Die je nach Strömungsrichtung selbstausrichtende Funktion ist dadurch gegeben, daß bei Umkehrung der Strömungsrichtung die durch die umgelegten Kanten ausgebideten Taschen von der Strömung erfaßt werden und die entstehenden Auftriebskräfte den Spoiler (1) selbsttätig ausrichten (Fig. 3)· Die beim Ausrichten des Spoilers (1) auftretenden Geräusche werden durch den bereits erwähnten Gummibelag (3) gedämpft (Fig. 4).The self-aligning function, depending on the direction of flow, is achieved by the fact that when the direction of flow is reversed, the pockets formed by the folded edges are caught by the flow and the resulting buoyancy forces automatically align the spoiler (1) (Fig. 3) . The noises that occur when the spoiler (1) is aligned are dampened by the rubber covering (3) already mentioned (Fig. 4).

Zur Unterstützung des Spoilers (1) im ausgerichteten Zustand können zusätzlich pneumatische, hydraulische, mechanische oder elektromagnetische Vorrichtungen verwendet werden. Mittels dieser Vorrichtungen können auch Bremseffekte erzielt werden, wenn der Spoiler (1) eine der Strömung entgegengesetzte Anstellung erfährt. Damit können Bremsvorgänge des Zuges verkürzt werden.To support the spoiler (1) in the aligned state, pneumatic, hydraulic, mechanical or electromagnetic devices can also be used. Braking effects can also be achieved using these devices if the spoiler (1) is positioned in the opposite direction to the flow. This can shorten the braking processes of the train.
