Description

Die Erfindung betrifft ein Schienenfahrzeug, insbesondere einen Straßen- oder Stadtbahnwagen für den Nahverkehr, bei dem zwischen dem Schienenniveau und der Unterkante der Frontwand oder der Unterkante einer frontseitig befestigten Schürze eine spaltförmige Öffnung besteht.The invention relates to a rail vehicle, in particular a road or light rail vehicles for local traffic, where between the rail level and the lower edge of the front wall or the lower edge of a front attached apron has a slit-shaped opening.

Die zuvor definierte spaltförmige Öffnung hat beispielsweise bei niederflurigen Schienenfahrzeugen ein Höhenmaß in der Größenordnung von 220 mm bis 260 mm, wenn das Fahrzeug auf ebenem Gleis fährt. Bei dem Befahren von Mulden oder Kuppen der Schienenanlage beträgt das besagte Höhenmaß ca. 60 mm bzw. 350 mm. Wegen der spaltförmigen Öffnung besteht bei einem Unfall die Gefahr, dass vor dem Fahrzeug befindliche Personen oder Gegenstände unter das Fahrzeug geraten können.The previously defined gap-shaped opening has, for example, low-floor Rail vehicles have a height of the order of 220 mm to 260 mm when the vehicle is traveling on a level track. When driving on Troughs or crests of the rail system are approx. 60 mm or 350 mm. Because of the gap-shaped opening there is one Accident the risk of people or objects in front of the vehicle can get under the vehicle.

Der Erfindung liegt daher die Aufgabe zugrunde, bei einem Schienenfahrzeug der gattungsgemäßen Art die spaltförmige Öffnung auf möglichst einfache Weise so zu verkleinern, dass Personen oder Gegenstände nicht unter das Fahrzeug geraten können.The invention is therefore based on the object in a rail vehicle the generic type, the gap-shaped opening in the simplest possible Way to zoom out so that people or objects are not covered by the Can get into the vehicle.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass das Fahrzeug eine die spaltförmige Öffnung abdeckende, höhenverstellbare Bugschürze aufweist. Diese im Bereich unterhalb der Frontwand oder der festen Schürze angeordnete bewegliche Bugschürze nimmt eine mittlere Stellung ein, wenn das Fahrzeug auf ebenen Schienen steht oder fährt, wobei auch eine Neigung der ebenen Schienen vorliegen kann. Bei dem Befahren einer Mulde der Schienenanlage wird die Bugschürze aufwärts bewegt und bei dem Befahren einer Kuppe entsprechend abgesenkt. This object is achieved in that the vehicle has a height-adjustable front apron covering the gap-shaped opening. This is arranged in the area below the front wall or the fixed apron movable front apron occupies a middle position if that Vehicle stands or drives on level rails, with an inclination of the flat rails can be present. When driving on a trough of the rail system the front apron is moved upwards and when driving on one Hill lowered accordingly.

Das Schienenfahrzeug hat einen z. B. aus mehreren Modulen gebildeten Wagenkasten 5 (siehe Fig. 2), der auf einer entsprechenden Anzahl von Fahrwerken 6 abgestützt ist. Im vorderen Bereich des Fahrzeuges ist eine Bugschürze 4 angeordnet, die eine spaltförmige Öffnung 3 zwischen dem Schienenniveau 1 und der Unterkante der Frontwand 2 abdeckt, wobei diese Unterkante auch zu einer frontseitig angebrachten festen Schürze gehören kann. Es ist möglich, die Bugschürze 4 einteilig oder durch Zusammenfügen von beispielsweise drei Teilstücken herzustellen. Die vordere Außenfläche der Bugschürze 4 kann eine Beschichtung aus weichen Material aufweisen.The rail vehicle has a z. B. formed from several modules car body 5 (see Fig. 2) on a corresponding number of trolleys 6 is supported. In the front area of the vehicle is a front apron 4 arranged, a gap-shaped opening 3 between the rail level 1 and the lower edge of the front wall 2, this lower edge can also belong to a fixed apron attached to the front. It is possible to make the front apron 4 in one piece or by joining it together for example, to produce three sections. The front outer surface of the Front apron 4 can have a coating of soft material.

Die Bugschürze 4 ist höhenverstellbar, insbesondere mit Hilfe einer Verstelleinheit 7. Die gemäß Fig. 5 doppelt vorgesehenen Verstelleinheiten 7 können jeweils als elektro-mechanischer Spindelantrieb ausgeführt sein. Die Verstelleinheiten 7 befinden sich vorzugsweise hinter der Frontwand 2 des Fahrzeuges, ggf. auch in dessen Fahrerraum. The front apron 4 is adjustable in height, in particular with the aid of an adjustment unit 7. The adjustment units 7 provided twice according to FIG. 5 can each be designed as an electro-mechanical spindle drive. The adjustment units 7 are preferably located behind the front wall 2 of the vehicle, possibly also in the driver's compartment.

Wenn das Fahrzeug, wie in Fig. 1 dargestellt, auf ebenen Schienen steht oder fährt, nimmt die Bugschürze 4 eine mittlere Stellung ein. Im Sinne der gewollten Abdeckung der besagten spaltförmigen Öffnung 3 wird die Bugschürze 4 nach unten verstellt, wenn das Fahrzeug eine Kuppe der Schienenanlage befährt (siehe Fig. 2). Sobald das Fahrzeug dagegen durch eine Mulde fährt, erfolgt ein Verstellen der Bugschürze 4 nach oben. In allen diesen Betriebssituationen hat die spaltförmige Öffnung 3 ein relativ geringes, weitgehend konstantes Höhenmaß (Größenordnung etwa 120 mm), so dass bei einem Unfall keine Personen oder größeren Gegenstände unter das Fahrzeug geraten können.If the vehicle, as shown in Fig. 1, is on level rails or drives, the front apron 4 takes a middle position. In the sense of the wanted Covering said slit-shaped opening 3 becomes front apron 4 adjusted downwards if the vehicle has a crest of the rail system travels (see Fig. 2). On the other hand, as soon as the vehicle drives through a hollow, the front apron 4 is adjusted upwards. In all of these operating situations the slit-shaped opening 3 has a relatively small, largely constant Height measure (order of magnitude about 120 mm), so in the event of an accident no people or larger objects get under the vehicle can.

Um die gewünschte Höhenverstellung der Bugschürze 4 auf einfache Weise zu erreichen, ist eine Sensoreinheit 8 vorgesehen, die mindestens ein Messelement aufweist. Gemäß Fig. 4 ist die als Näherungssensor ausgebildete Sensoreinheit 8 zwischen dem Wagenkasten 5 und einem von der Drehachse 6a entfernten Rahmenteil 6b des Fahrwerkes 6 angeordnet. Dort erfasst die Sensoreinheit 8 die dem Verlauf des Schienenniveaus 1 bei Kuppen- bzw. Muldenfahrt proportionalen Nickbewegungen des Fahrwerkes 6 gegenüber dem Wagenkasten 5 und ausserdem Höhenbewegungen des Wagenkastens 5 auf Grund der Sekundärfederung des Schienenfahrzeuges. Über diese Messung des jeweiligen Abstandsmaßes zwischen Wagenkasten 5 und Rahmenteil 6b des Fahrwerkes 6 wird die Bugschürze 4 in ihrer Höhe entsprechend verstellt. Die in Fig. 4 angegebene Position A des Rahmenteiles 6b entspricht der Betriebssituation nach Fig. 1 "ebenes Schienenniveau 1" ; Position B gehört zu Fig. 2 "Kuppenfahrt" und Position C zu Fig. 3 "Muldenfahrt".To the desired height adjustment of the front apron 4 in a simple manner To achieve, a sensor unit 8 is provided, which has at least one measuring element having. 4 is designed as a proximity sensor Sensor unit 8 between the car body 5 and one of the axis of rotation 6a distant frame part 6b of the chassis 6 arranged. There captured the Sensor unit 8 which follows the course of the rail level 1 in the case of crests or Trough travel proportional pitch movements of the chassis 6 compared the car body 5 and also height movements of the car body 5 due to the secondary suspension of the rail vehicle. About these Measurement of the respective distance between the car body 5 and the frame part 6b of the chassis 6, the front apron 4 is corresponding in height adjusted. The position A of the frame part 6b indicated in FIG. 4 corresponds to the operating situation according to FIG. 1 "level rail level 1"; position B belongs to FIG. 2 "crest ride" and position C to FIG. 3 "trough ride".

Als Alternative zu der vorbeschriebenen Anordnung kann die Sensoreinheit 8 in der Nähe der Frontwand 2 des Wagenkastens 5 plaziert sein (nicht dargestellt). Die Sensoreinheit 8 erfaßt dort den jeweiligen Abstand zwischen dem Wagenkasten 5 und der Oberkante des Schienenniveaus 1 unmittelbar, wobei der jeweils gemessene Abstand für Hub- oder Senkbewegungen der Bugschürze 4 entsprechend umgesetzt wird. As an alternative to the arrangement described above, the sensor unit 8 be placed near the front wall 2 of the car body 5 (not shown). The sensor unit 8 detects the respective distance between the Car body 5 and the upper edge of the rail level 1 immediately, wherein the measured distance for lifting or lowering movements of the front apron 4 is implemented accordingly.
