Description

Die Erfindung betrifft ein Schienenfahrzeug mit einem kopfseitig angeordneten Personeneinklemmschutz.The invention relates to a rail vehicle with a head side arranged Personeneinklemmschutz.

Schienenfahrzeuge für den Personennahverkehr, insbesondere Straßenbahnen, teilen sich den innerstädtischen Verkehrsraum oft mit anderen Verkehrsteilnehmern. Um bei Unfällen mit Fußgängern zu verhindern, dass diese unter die Straßenbahn geraten, wird ein Spalt zwischen dem Untergestell der Straßenbahn und dem Fahrbahnoberfläche so gering wie möglich gehalten. Dieser ist im Fahrbetrieb jedoch meist nicht konstant, beispielsweise durch wechselnde Anzahlen zu befördernder Personen oder durch Wankbewegungen des Fahrzeugs.Rail vehicles for local passenger transport, in particular trams, often share the inner-city traffic area with other road users. In order to prevent accidents with pedestrians that they get under the tram, a gap between the base of the tram and the road surface is kept as low as possible. However, this is usually not constant when driving, for example, by changing numbers to be carried persons or by rolling movements of the vehicle.

Die EP 1 123 851 B1 und die DE 214 049 C offenbaren jeweils ein Schienenfahrzeug mit einer frontseitig befestigten, in der Höhe schwenkbar angelenkten Schürze zur weitgehenden Konstanthaltung eines Spalts zwischen einem Schienenniveau und der Unterkante der Schürze. Die Schürze der DE 214 049 C weist dazu Räder auf, welche auf den Schienen laufen. Um Kurvenfahrten zu ermöglichen, ist die Schürze horizontal schwenkbar. Die EP 1 123 851 B1 lehrt hingegen Sensoren zur Vermessung des Spalts und Aktoren zum Verstellen der Bugschürze in Abhängigkeit der gemessenen Werte.The EP 1 123 851 B1 and the DE 214 049 C each disclose a rail vehicle with a front mounted, hinged in height apron to keep largely a gap between a rail level and the lower edge of the skirt. The apron of DE 214 049 C has wheels that run on the rails. To allow cornering, the skirt is horizontally pivotable. The EP 1 123 851 B1 On the other hand, it teaches sensors for measuring the gap and actuators for adjusting the front apron depending on the measured values.

Auch die Druckschriften GB 1912 09707 A und US 528 048 A offenbaren Frontschürzen für Schienenfahrzeuge, deren Abstand zur Schiene konstant haltbar sind.Also the pamphlets GB 1912 09707 A and US 528 048 A reveal front aprons for rail vehicles, whose distance from the rail can be kept constant.

Der Erfindung liegt die Aufgabe zugrunde, einen einfachen und sicheren Personeneinklemmschutz vorzuschlagen.The invention has the object to provide a simple and secure Personeneinklemmschutz.

Gelöst wird die Aufgabe durch den Gegenstand des unabhängigen Patentanspruchs 1. Weiterbildungen und Ausgestaltungen der Erfindung finden sich in den Merkmalen der abhängigen Patentansprüche wieder.The object is achieved by the subject matter of independent claim 1. Further developments and refinements of Invention can be found in the features of the dependent claims again.

Ein erfindungsgemäßes Schienenfahrzeug, beispielsweise eine Straßenbahn, umfasst einen kopfseitig angeordneten Personeneinklemmschutz, welcher in vertikaler Richtung verschiebbar an einem Untergestell des Schienenfahrzeugs angeordnet ist. Darüber hinaus umfasst das Schienenfahrzeug zumindest einen Anschlag für den Personeneinklemmschutz, welcher in einem vorgegebenen Abstand in vertikaler Richtung größer Null zum Untergestell angeordnet ist. Der Personeneinklemmschutz befindet sich beim Anliegen an dem Anschlag in einer Ruheposition. Er lässt sich somit zum Untergestell hin und somit von einem Gleiskörper weg aus der Ruheposition heraus vertikal verschieben. In Richtung des Gleiskörpers und somit vom Untergestell weg verhindert der Anschlag eine weitere Verschiebung des Personeneinklemmschutzes, da dieser nur bis zum Anliegen an dem Anschlag verschiebbar ist. Des Weiteren umfasst das Schienenfahrzeug zumindest ein Rückstellmittel, welches ausgebildet ist, eine vorgegebene Rückstellkraft auf den Personeneinklemmschutz aufzubringen, welche in Richtung des Anschlags bzw. in Richtung des Gleiskörpers wirkt, um den Personeneinklemmschutz bis zum Anliegen an dem Anschlag und damit bis in seine Ruheposition zu verschieben, sollte er aus der Ruheposition heraus verschoben sein.A rail vehicle according to the invention, for example a tram, comprises a person trap protection arranged on the head side, which is arranged displaceably in the vertical direction on a subframe of the rail vehicle. In addition, the rail vehicle comprises at least one stop for the person trap protection, which is arranged at a predetermined distance in the vertical direction greater than zero to the base. The Personeneinklemmschutz is when it concerns the stop in a rest position. It can thus be moved towards the underframe and thus move vertically away from the rest position from a track body. In the direction of the track body and thus away from the base of the stopper prevents further displacement of Personeneinklemmschutzes, since this is only displaced until it abuts against the stop. Furthermore, the rail vehicle comprises at least one restoring means, which is designed to apply a predetermined restoring force to the anti-trap protection, which acts in the direction of the stop or in the direction of the track body to the Personeneinklemmschutz to rest on the stop and thus to its rest position move, it should be moved out of the rest position.

Das Rückstellmittel ist entsprechend derart ausgebildet, bei einer Einwirkung einer von außen auf den Personeneinklemmschutz aufgebrachten Kraft, welche entgegen der Rückstellkraft wirkt und diese überschreitet, eine Verschiebung des Personeneinklemmschutzes in Richtung des Untergestells des Schienenfahrzeugs zu ermöglichen. Die Kraft muss zusätzlich noch die Schwerkraft übersteigen. Ist das Schienenfahrzeug horizontal ausgerichtet wirkt die Rückstellkraft in Richtung der Schwerkraft. Sie verstärkt diese damit der Personeneinklemmschutz schneller in Richtung des Gleiskörpers verschoben wird, wenn er aus der Ruheposition heraus verschoben ist und keine äußere Kraft auf ihn einwirkt.The restoring means is correspondingly designed in such a way, upon action of an applied from the outside on the Personeneinklemmschutz force which acts against the restoring force and this exceeds, to allow a shift of Personeneinklemmschutzes in the direction of the undercarriage of the rail vehicle. The force must also exceed gravity. If the rail vehicle is aligned horizontally, the restoring force acts in the direction of gravity. It reinforces this so that the Personeneinklemmschutz is moved faster towards the track body when it is shifted out of the rest position and no external force acts on him.

Als Rückstellmittel dient weitergebildet zumindest eine Feder, beispielsweise zumindest eine Gasdruckfeder.At least one spring, for example at least one gas pressure spring, serves as a return means.

Zur vertikalen Führung des Personeneinklemmschutzes weist das Schienenfahrzeug insbesondere zumindest eine geeignete Axialführung auf. Insbesondere dadurch lassen sich die Bewegungsfreiheitsgrade des Personeneinklemmschutzes auf die translatorische Verschiebbarkeit in vertikaler Richtung begrenzen.For vertical guidance of Personeneinklemmschutzes the rail vehicle in particular at least one suitable axial guidance. In particular, this allows the degrees of freedom of movement of Personeneinklemmschutzes limit the translational displacement in the vertical direction.

Darüber hinaus ist der Anschlag erfindungsgemäß über eine Haltevorrichtung am Schienenfahrzeug angeordnet, welche derart ausgebildet ist, dass der vorgegebene Abstand des Anschlags zum Untergestell einstellbar ist. Gemäß einer Ausführungsform ist die Haltevorrichtung als Schraube ausgebildet. Es handelt sich somit um eine Einstellschraube.In addition, the stop is arranged according to the invention via a holding device on the rail vehicle, which is designed such that the predetermined distance of the stop to the base frame is adjustable. According to one embodiment, the holding device is designed as a screw. It is therefore an adjustment screw.

Bei vorgegebenen Rahmenbedingungen, beispielsweise einem ungeladenen, stehenden Schienenfahrzeug, ist ein vorgegebener Abstand des Personeneinklemmschutzes vom Gleiskörper somit einfach einstellbar. Dieser wird zwar dynamisch im Wesentlichen konstant gehalten, Einfederungen werden dynamisch ausgeglichen, jedoch erfolgt dies insbesondere nicht aktiv, mittels Sensoren und Aktoren, sondern passiv mittels eines passiven Rückstellmittels. Der eingestellte Abstand des Personeneinklemmschutzes vom Gleiskörper wird nicht unterschritten, so dass jederzeit der gewünschte Schutz von Personen gegeben ist.Given a given framework, for example, an unloaded, stationary rail vehicle, a predetermined distance of Personeneinklemmschutzes of the track is thus easily adjustable. Although this is kept substantially constant dynamically, deflections are compensated dynamically, but this is done in particular not actively, by means of sensors and actuators, but passively by means of a passive return means. The set distance of Personeneinklemmschutzes of the track body is not fallen below, so that at any time the desired protection of persons is given.

Der Gleiskörper oder auch Oberbau eines Gleises genannt, umfasst das Gleisbett und die darauf montierten Schienen und auch eine gegebenenfalls installierte Schallisolierung. Bei Straßenbahnen umfasst der Oberbau oft eine Asphaltschicht, auf welcher sich auch Fußgänger bewegen oder welche einen Fahrbahnbelag für Straßenfahrzeuge bildet.The track or superstructure of a track called, includes the track bed and mounted on rails and also an optionally installed soundproofing. In trams, the superstructure often includes an asphalt layer on which also pedestrians move or which forms a road surface for road vehicles.

Um beispielsweise bei einer starken Einfederung des Schienenfahrzeugs, beispielsweise bei Vollladung oder bei Wankbewegungen, Beschädigungen des Personeneinklemmschutzes oder Beeinträchtigungen der Fahreigenschaften des Schienenfahrzeugs zu vermeiden, weist der Personeneinklemmschutz zumindest einen Abstandhalter auf, welcher auf einer dem Gleiskörper zugewandten Unterseite des Personeneinklemmschutzes angeordnet ist, um in Kontakt mit einem Gleiskörper zu kommen und um den Personeneinklemmschutz bei einem Kontakt des Abstandhalters mit einem Gleiskörper aus der Ruheposition heraus zu verschieben. Dazu wird eine Kraft auf den zumindest einen Abstandhalter vom Gleiskörper aufgebracht, welche entgegen der Rückstellkraft des Rückstellmittels wirkt und diese übersteigt, so dass der Personeneinklemmschutz in Richtung des Untergestells des Schienenfahrzeugs verschoben wird. Über den Abstandhalter wird die entgegen der Rückstellkraft des Rückstellmittels wirkende Kraft auf den Personeneinklemmschutz aufgebracht.For example, at a strong deflection of the rail vehicle, for example, during full load or roll motions, damage to the Personeneinklemmschutzes or impairment of the handling characteristics of the rail vehicle To avoid, the Personeneinklemmschutz has at least one spacer which is arranged on a track facing the track body of Personeneinklemmschutzes to come into contact with a track body and to move the Personeneinklemmschutz at a contact of the spacer with a track body from the rest position. For this purpose, a force is applied to the at least one spacer from the track body, which counteracts the restoring force of the return means and exceeds this, so that the Personeneinklemmschutz is moved in the direction of the undercarriage of the rail vehicle. About the spacer, the force acting against the restoring force of the return means force is applied to the Personeneinklemmschutz.

Gemäß einer vorteilhaften Weiterbildung ist der zumindest eine Abstandhalter als Wälzkörper, insbesondere als Rad, ausgebildet. So erzeugt er beim Kontakt mit dem Gleiskörper einen geringen Widerstand. Eine Ausgestaltung der Erfindung sieht vor, dass der zumindest eine Wälzkörper im Personeneinklemmschutz gelagert und größtenteils durch ihn verkleidet ist. Die Achse, um welches ein Rad als Wälzkörper frei drehbar ist, liegt somit innerhalb des Personeneinklemmschutzes. Die Achse steht insbesondere senkrecht zur Längsachse des Schienenfahrzeugs und somit senkrecht zu dessen Fahrtrichtung, so dass das Rad in Fahrtrichtung abrollt. Der Abstandhalter stellt einen vorgegebenen Abstand zwischen der Unterseite des Personeneinklemmschutzes und dem Gleiskörper sicher.According to an advantageous development, the at least one spacer is formed as a rolling body, in particular as a wheel. So it produces a low resistance when in contact with the track body. An embodiment of the invention provides that the at least one rolling element is mounted in Personeneinklemmschutz and largely covered by him. The axis about which a wheel is freely rotatable as a rolling element, thus lies within the Personeneinklemmschutzes. The axis is in particular perpendicular to the longitudinal axis of the rail vehicle and thus perpendicular to the direction of travel, so that the wheel rolls in the direction of travel. The spacer ensures a predetermined distance between the bottom of Personeneinklemmschutzes and the track body.

Der oder die Wälzkörper, insbesondere das oder die Räder, sind nicht an die Schienen, entlang welcher das Schienenfahrzeug geführt wird, gebunden. Gerade bei Gleiskörpern mit einem Fahrbahnbelag für Straßenfahrzeuge als Oberbau, können sie mit diesem in Kontakt kommen und entsprechend auf diesem abrollen.The one or more rolling elements, in particular the one or more wheels are not bound to the rails along which the rail vehicle is guided. Especially for track structures with a road surface for road vehicles as a superstructure, they can come into contact with this and roll accordingly on this.

Daher ist der zumindest eine Wälzkörper, insbesondere das zumindest eine Rad, nicht zwingend aus Stahl herzustellen, vielmehr ist es vorteilhaft, wenn es ein Polymer, insbesondere ein Elastomer umfasst. Das zumindest eine Rad umfasst beispielsweise einen Reifen, insbesondere einen Luftreifen.Therefore, the at least one rolling element, in particular the at least one wheel, is not necessarily made of steel, rather, it is advantageous if it comprises a polymer, in particular an elastomer. The at least one wheel comprises, for example, a tire, in particular a pneumatic tire.

Gemäß einer weiteren Weiterbildung der Erfindung ist der Personeneinklemmschutz stirnseitig gepolstert. Dadurch können schwere Verletzungen von Personen verhindert werden. Eine Polsterung umfasst ein Polstermaterial, insbesondere einen geeigneten Schaumstoff.According to a further embodiment of the invention, the Personeneinklemmschutz is frontally padded. This can prevent serious personal injury. A padding comprises a padding material, in particular a suitable foam.

Die Erfindung lässt zahlreiche Ausführungsformen zu. Sie wird anhand der nachfolgenden Figuren näher erläutert, in denen jeweils ein Ausgestaltungsbeispiel dargestellt ist. Gleiche Elemente in den Figuren sind mit gleichen Bezugszeichen versehen.

The invention allows numerous embodiments. It will be explained in more detail with reference to the following figures, in each of which a design example is shown. Identical elements in the figures are provided with the same reference numerals.

Fig. 2
shows a Personeneinklemmschutz in perspective from below.

In Fig. 1 ist ein vorder, unterer Teil eines erfindungsgemäßen Schienenfahrzeugs schematisch im Schnitt dargestellt. Eine Kontur des Untergestells 9 des Schienenfahrzeugs ist gestrichelt dargestellt. An dem Untergestell 9 ist ein erfindungsgemäßer Personeneinklemmschutz 1 montiert. Er ist über eine Haltevorrichtung 4 und über ein Rückstellmittel 3 an dem Schienenfahrzeug befestigt. Er ist in Einfederrichtung des Schienenfahrzeugs axial geführt und hier entlang der Haltevorrichtung 4 und entlang einer Führung 8 vertikal verschiebbar. Die Haltevorrichtung 4 weist einen vom Untergestell 9 beabstandet angeordneten Anschlag 2 für den Personeneinklemmschutz 1 auf, bis zu welchem der Personeneinklemmschutz verschiebbar ist. Das Rückstellmittel 3, hier eine Gasdruckfeder, ist ausgebildet, eine vorgegebene Kraft auf den Personeneinklemmschutz 1 aufzubringen, welche in Richtung des Anschlags 2 wirkt, um den Personeneinklemmschutz 1 in Richtung des Anschlags, insbesondere bis zum Anschlag, zu verschieben.In Fig. 1 is a front, lower part of a rail vehicle according to the invention shown schematically in section. A contour of the undercarriage 9 of the rail vehicle is shown in dashed lines. On the undercarriage 9 an inventive Personeneinklemmschutz 1 is mounted. It is attached via a holding device 4 and a return means 3 to the rail vehicle. It is axially guided in the compression direction of the rail vehicle and here along the holding device 4 and along a guide 8 vertically displaceable. The holding device 4 has a spaced from the base 9 stop 2 for the Personeneinklemmschutz 1, to which the Personeneinklemmschutz is displaced. The return means 3, here a gas spring, is designed to apply a predetermined force to the anti-trap protection 1 which acts in the direction of the stop 2 in order to displace the anti-pinch protection 1 in the direction of the stop, in particular until it stops.

Gleichzeitig lässt das Rückstellmittel 3 ein Verschieben des Personeneinklemmschutzes 1 in Richtung des Untergestells 9 des Schienenfahrzeugs zu. Dazu ist eine Kraft notwendig, welche entgegen einer vom Rückstellmittel 3 aufgebrachten Rückstellkraft wirkt und welche größer ist als die Summe aus der Rückstellkraft und der Schwerkraft des Personeneinklemmschutzes 1. Die Bewegungsrichtung des Personeneinklemmschutzes ist mit dem Pfeil 10 veranschaulicht.At the same time, the return means 3 allows the passenger trap protection 1 to be displaced in the direction of the undercarriage 9 of the rail vehicle. For this purpose, a force is necessary, which counteracts a restoring force applied by the restoring means 3 and which is greater than the sum of the restoring force and the gravity of the Personeneinklemmschutzes 1. The direction of movement of Personeneinklemmschutzes is illustrated by the arrow 10.

Der Anschlag 2 ist hier Teil der Haltevorrichtung 4 und gemeinsam als Schraube ausgebildet. Durch Drehen der Schraube wird der vertikale Abstand des Anschlags 2 zum Untergestell 9 reguliert. Aus der Unterseite 6 des Personeneinklemmschutzes 1 ragt ein Rad, welches als Abstandhalter 5 dient. Durch das Rad wird gegebenenfalls die Kraft zum Verschieben des Personeneinklemmschutzes 1 vom Anschlag 2 weg hin zum Untergestell 9 aufgebracht, indem das Rad in Kontakt mit dem hier nicht skizzierten Gleiskörper kommt, beispielsweise beim Einfedern des Schienenfahrzeugs.The stopper 2 is here part of the holding device 4 and formed together as a screw. By turning the screw, the vertical distance of the stopper 2 to the base 9 is regulated. From the bottom 6 of Personeneinklemmschutzes 1 protrudes a wheel which serves as a spacer 5. By the wheel, if necessary, the force for moving the Personeneinklemmschutzes 1 from the stop 2 away towards the base 9 is applied by the wheel comes into contact with the track body not sketched here, for example, during compression of the rail vehicle.

Der Personeneinklemmschutz umfasst hier eine stirnseitig angeordnete Polsterung 7 unterhalb des Rückstellmittels 3.The Personeneinklemmschutz here comprises a front side arranged padding 7 below the return means. 3

Fig. 2 zeigt einen erfindungsgemäßen Personeneinklemmschutz 1 schematisch in dreidimensionaler Ansicht von unten. Der Personeneinklemmschutz 1 ist an einem Untergestell eines Schienenfahrzeugs, beispielsweise unter einem Wagenkasten des Schienenfahrzeugs, insbesondere kopfseitig, montierbar. Fig. 2 shows a Personeneinklemmschutz 1 according to the invention schematically in three-dimensional view from below. The Personeneinklemmschutz 1 is on a subframe of a rail vehicle, for example, under a car body of the rail vehicle, in particular head side, mountable.

Zwei Räder als Abstandhalter 5 sind im Personeneinklemmschutz 1 gelagert und größtenteils vom Personeneinklemmschutz 1 verdeckt. Sie ragen aus der Unterseite 6 des Personeneinklemmschutzes 1 heraus, um den Personeneinklemmschutz 1 bei einem Kontakt der Räder mit einem Gleiskörper aus der Ruheposition heraus zu verschieben.Two wheels as spacers 5 are mounted in Personeneinklemmschutz 1 and largely covered by Personeneinklemmschutz 1. They protrude from the bottom 6 of the person trap protection 1 out to move the Personeneinklemmschutz 1 at a contact of the wheels with a track body from the rest position out.

Um den Personeneinklemmschutz 1 aus seiner Ruheposition heraus zu verschieben, muss eine Kraft auf den Personeneinklemmschutz 1 aufgebracht werden, welche entgegen der Rückstellkraft der Rückstellmittel 3 wirkt und diese übersteigt, so dass der Personeneinklemmschutz 1 in Richtung des Untergestells des Schienenfahrzeugs verschiebbar ist. Diese Kraft wird vom Gleiskörper auf die Räder aufgebracht und über die Räder übertragen. Frontseitig ist der Personeneinklemmschutz 1 wiederum mit einer Polsterung 7 versehen. Als Rückstellmittel 3 sind abermals zwei Gasdruckfedern vorgesehen.In order to move the Personeneinklemmschutz 1 out of its rest position, a force on the Personeneinklemmschutz 1 are applied, which counteracts the restoring force of the return means 3 and exceeds this, so that the Personeneinklemmschutz 1 is displaceable in the direction of the undercarriage of the rail vehicle. This force is applied by the track on the wheels and transmitted through the wheels. Front side of the person trap protection 1 is again provided with a padding 7. As a return means 3 again two gas springs are provided.
