Schienenfahrzeug mit einem Schneeräumer Die Erfindung betrifft ein Schienenfahrzeug mit einem Schnee¬ räumer nach dem Oberbegriff des Patentanspruches 1. Rail vehicle with a snowplow The invention relates to a rail vehicle with a snow ¬ reamer according to the preamble of claim 1.
Es ist bekannt, Schienenfahrzeuge, insbesondere Lokomotiven, mit Schneeräumern auszustatten, um Schnee unterschiedlicher Dichte bis zu einer maximalen Höhe von 800 mm bis 1.000 mm über den Fahrschienen bei Fahrgeschwindigkeiten von über 100 km/h, möglichst bis 160 km/h, entgleisungssicher vom Fahrweg zu räumen. Aus der Patentschrift EP 1 070 792 Bl ist ein Schienenfahrzeug, insbesondere eine Lokomotive mit einem Tragrahmen und mit einem Fahrbahnräumer bekannt. Der Fahrbahnräumer weist zwei C-förmig profilierte Räumschilde auf, die pflugförmig auf eine Spitze zulaufend angeordnet sind. Die Räumschilde sind am Tragrahmen über Halterungen befestigt, deren Verformungen bei einer Stoßbelastung im Wesentlichen parallel zur Ebene des Tragrahmens gehalten bleiben. Bei einer Kollision werden dadurch einerseits die Gefahr einer Beschädigung des Tragrahmens und andererseits die Gefahr einer Entgleisung durch einen nach unten weggebogenen oder abgerissenen Fahrbahnräumer vermindert. It is known to equip rail vehicles, especially locomotives, with snow clearers to different snow density up to a maximum height of 800 mm to 1,000 mm above the rails at speeds of over 100 km / h, possibly up to 160 km / h, derailment safe from the track to vacate. Patent EP 1 070 792 B1 discloses a rail vehicle, in particular a locomotive with a supporting frame and with a roadway cleaner. The Fahrbahnräumer has two C-shaped profiled scrapers, which are arranged plow-shaped tapering to a peak. The Räumschilde are attached to the support frame via brackets, the deformations remain held at a shock load substantially parallel to the plane of the support frame. In a collision on the one hand the risk of damage to the support frame and on the other hand, the risk of derailment is reduced by a downwardly bent or demolished Fahrbahnräumer.
Die Patentveröffentlichung JP 10252030 A offenbart ein Schienenfahrzeug zum Schneeräumen, umfassend eine Mehrfach-Pflug- einrichtung mit einem Rahmen, der über einen Schaft mit vertikaler Drehachse mit dem Schienenfahrzeug verbunden ist, so¬ wie eine Unter-Pflugeinrichtung, die von einer Hubeinrichtung getragen wird. Die Hubeinrichtung ist mit dem Rahmen hinter der Mehrfach-Pflugeinrichtung verbunden. Die Pflugscharen der Mehrfach-Pflugeinrichtung können zum Räumen des Schnees oberhalb der Schienenoberkanten in eine V-förmige Stellung, in eine gerade Stellung oder in eine umgekehrt V-förmige Stel¬ lung gebracht werden. Ein V-förmiger Unter-Pflug der Unter- Schneepflugeinrichtung räumt den Schnee unterhalb der Schienenoberkanten zwischen zwei Fahrschienen. Der Unter-Pflug weist eine Leitfläche zum Abführen von Schnee in horizontaler Richtung auf, was ein Herabfallen von Schnee zwischen die Fahrschienen verhindert. The patent publication JP 10252030 A discloses a rail vehicle for clearing snow, comprising a multi-plow device with a frame which is connected via a shaft with a vertical axis of rotation with the rail vehicle, as ¬ a sub-plow, which is supported by a lifting device. The lifting device is connected to the frame behind the multi-plow. The plowshares of the multiple plowing device can be brought to clear the snow above the rail upper edges in a V-shaped position, in a straight position or in an inverted V-shaped Stel ¬ ment. A V-shaped under-plow of the bottom Snow plowing device clears the snow below the rail upper edges between two rails. The sub-plow has a baffle for discharging snow in the horizontal direction, preventing snow from falling between the rails.

The clearing flaps loosen and remove any remaining snow and other remnants left by the snow plow. The device cleverly removes snow and is made of the thinnest material.
Aus dem Patent US 51,829 A ist ein Schneepflug für Schienen¬ fahrzeuge zur Entfernung von Schnee und Eis von den Fahr- schienen und aus dem Gleisbett bekannt. Der Schneepflug um¬ fasst einen vertikal und lateral selbst-einstellbaren Räumer, zwei bewegliche Seitenflügel zur Abführung von Schnee und Eis und einen Federarm zur Einhaltung eines Abstandes zwischen Räumer und Fahrschienen, um den Betrieb des Schneepflugs durch Hindernisse nicht zu beeinträchtigen. From US 51.829 A, a snow plow for rail vehicles ¬ for the removal of snow and ice has appeared from the driving and known from the track bed. The snow plow encompasses a vertically and laterally self-adjustable scraper, two movable side wings for removing snow and ice, and a spring arm for maintaining a distance between scraper and rails, so as not to impair the operation of the snowplow by obstacles.
Die Offenlegungsschrift DE 10 2009 019 576 AI zeigt einen gepfeilten Schneeräumer mit zwei Seitenflächen für ein Schienenfahrzeug. Um einen solchen Schneeräumer strömungstechnisch günstig auszugestalten, sind in den Seitenflächen Durchbrüche vorhanden. Die Durchbrüche sind mit Leitschaufeln versehen, die derart angeordnet und ausgestaltet sind, dass die Luft¬ strömung nach unten abgelenkt wird. Die Offenlegungsschrift DE 199 33 914 AI offenbart einenThe published patent application DE 10 2009 019 576 AI shows a swept snow clearer with two side surfaces for a rail vehicle. To make such a snowplow aerodynamically favorable, breakthroughs are present in the side surfaces. The openings are provided with guide vanes, which are arranged and configured such that the air ¬ flow is deflected downward. The published patent application DE 199 33 914 A1 discloses a
Fahrbahnräumer für ein Schienenfahrzeug, der aus einem oder mehreren Räumschildern besteht, die mit einer Halterung am Tragrahmen des Schienenfahrzeugs befestigt sind. Bei der Be- festigung des sich über die gesamte Breite des Schienenfahrzeugs erstreckenden Fahrbahnräumers besteht das Problem, dass weit auseinanderliegende Befestigungsstellen vorzusehen sind, die eine hohe Fertigungsgenauigkeit und einen hohen Aufwand beim Einbau erfordern. Um einen einfach herzustellenden und zu montierenden Fahrbahnräumer zu schaffen, wird für den Fahrbahnräumer eine Halterung vorgeschlagen, die aus einer torsionsfesten Tragstruktur besteht, die mit ihrem oberen Ende mittig am Kopfträger befestigt ist und an deren unterem Ende der Räumschild befestigt ist. Roadway cleaner for a rail vehicle, which consists of one or more skid plates, which are fastened with a bracket on the support frame of the rail vehicle. At the time of consolidation of extending over the entire width of the rail vehicle Fahrbahnräumers there is the problem that far apart mounting points are provided, which require a high manufacturing accuracy and a high cost of installation. In order to create a simple to produce and to be mounted Fahrbahnräumer, a holder is proposed for the Fahrbahnräumer, which consists of a torsion-resistant support structure, which is attached with its upper end centered on the head carrier and attached to the lower end of the dozer blade.
Aus der Offenlegungsschrift DE 199 33 915 AI ist ein Fahr¬ bahnräumer für ein Schienenfahrzeug bekannt, der aus einem oder mehreren Räumschilden besteht, die mit einer Halterung am Tragrahmen des Schienenfahrzeugs befestigt sind. Um die Gefahr zu mindern, dass der Fahrbahnräumer bei einer Kollision mit einem Hindernis nach unten wegknickt und das Schienen¬ fahrzeug zum Entgleisen bringt und um zu vermeiden, dass sich bei einer Verformung der Halterung des Fahrbahnräumers der Tragrahmen mit verformt, wird vorgeschlagen, die Halterung so auszugestalten, dass der Fahrbahnräumer bei einer Kollision mit einem Hindernis unter Energieaufnahme durch in der Halte¬ rung angeordnete Energieverzehrelemente im wesentlichen pa¬ rallel zur Ebene des Tragrahmens gehalten bleibt. From the published patent application DE 199 33 915 AI a Fahr ¬ track scraper for a rail vehicle is known, which consists of one or more Räumschilden, which are fastened with a holder on the support frame of the rail vehicle. To reduce the risk that the Fahrbahnräumer kinks in a collision with an obstacle down and brings the rail ¬ vehicle to derailment and to avoid that deforms in a deformation of the support of the Fahrbahnräumers of the support frame, is proposed, the holder in such a way that the Fahrbahnräumer remains held in a collision with an obstacle with energy absorption by arranged in the holding ¬ tion energy absorbing elements substantially pa ¬ rallel to the plane of the support frame.
Bei der Befestigung eines Schneeräumers am Untergestell des Schienenfahrzeugs besteht hinsichtlich des freien Spaltes zwischen einer Unterkante des Schneeräumers und einer Ober¬ kante der Fahrschienen ein Zielkonflikt. Einerseits sollte die Spalthöhe mindestens einen Sicherheitsabstand einhalten, der sich aus einschlägigen Einschränkungsrechnungen unter Berücksichtigung von Nick- und Hubbewegungen des Fahrzeugkastens ergibt, um ein Aufschlagen des Schneeräumers auf die Fahrschienen zu vermeiden. Andererseits kann der errechnete Sicherheitsabstand sich als so groß erweisen, beispielsweise größer als 200 mm, dass Hindernisse wie etwa Holzschwellen durch den Spalt passen und vom Schneeräumer nicht weggeräumt werden können und hinter dem Schneeräumer angeordnete Kompo- nenten, wie Antennen, Sandungsanlagen oder dergleichen, nur unzureichend geschützt sind. When attaching a snowplow on the undercarriage of the rail vehicle is in terms of the free gap between a lower edge of the snowplow and a top ¬ edge of the rails a conflict of goals. On the one hand, the gap height should comply with at least one safety distance, which results from relevant restriction calculations, taking into account pitching and lifting movements of the vehicle body, in order to avoid impact of the snowplow on the rails. On the other hand, the calculated safety distance may prove to be so great, for example, greater than 200 mm, that obstacles such as wooden sleepers can pass through the gap and can not be cleared away by the snowplower and components arranged behind the snowplow. nenten, such as antennas, sanding systems or the like, are insufficiently protected.
Der Erfindung liegt daher die Aufgabe zugrunde ein gattungs¬ gemäßes Schienenfahrzeug mit einem Schneeräumer bereitzustel¬ len, wobei der Spalt zwischen Schneeräumer und Fahrschienen besser einstellbar ist. The invention is therefore based on the object a genus ¬ compliant rail vehicle bereitzustel ¬ len with a snow remover, the gap between the snow clearer and rails is better adjustable.
Die Aufgabe wird gelöst durch ein Schienenfahrzeug der ein¬ gangs genannten Art mit den im kennzeichnenden Teil des Patentanspruches 1 angegebenen Merkmalen. Demnach umfasst ein Schienenfahrzeug, insbesondere eine Lokomotive, einen Fahr¬ zeugkasten, der sich auf längs Fahrschienen verfahrbaren Fahrwerken federnd abstützt. Es umfasst ferner einen Schnee¬ räumer mit zwei pflugförmig auf eine Spitze zulaufenden, ei ¬ förmig profilierten Scharblechen und mit einem in Fahrtrichtung hinter den Scharblechen höhenverstellbar angeordneten Räumschild, dessen nach unten über eine Unterkante der Scharbleche hinaus ragender Überstand verstellbar ist. Dabei lie¬ gen die Scharbleche mit ihrer Unterkante auf einem Bodenblech auf, welches eine in Fahrtrichtung von der Unterkante vor¬ springende Schneidkante ausbildet. Erfindungsgemäß ist der Schneeräumer derart an einem Untergestell des Fahrzeugkastens befestigt, dass das Bodenblech des Schneeräumers einen durch maximale Einfederung des Fahrzeugkastens vorgegebenen Sicherheitsabstand zu den Fahrschienen einhält, wobei der Überstand des Räumschildes in Abhängigkeit des Sicherheitsabstandes und eines Radreifenverschleißes von Schienenrädern der Fahrwerke eingestellt ist. The object is achieved by a railway vehicle of the type mentioned at the outset a ¬ with the features specified in the characterizing part of patent claim 1. Accordingly, a rail vehicle, in particular a locomotive, a Fahr ¬ convincing box, which is resiliently supported on longitudinal rails movable chassis. It further comprises a snow ¬ spacers with two plow-shaped tapering on a tip, egg ¬ profiled Scharblechen and with a height adjustable behind the Scharblechen clearing blade in the direction of travel, the downward projecting beyond a lower edge of the Scharbleche supernatant is adjustable. In this case lie ¬ gen the blade sheets with their lower edge on a bottom plate on which forms a in the direction from the lower edge before ¬ jumping cutting edge. According to the invention the snow remover is fixed to a base frame of the vehicle body, that the floor pan of the snow remover maintains a predetermined by maximum deflection of the vehicle body safety distance to the rails, the supernatant of the dozer blade is set depending on the safety distance and a Radreifenverschleißes of rail wheels of the chassis.
Bei in Fahrt befindlichem Schienenfahrzeug teilt die Schneid¬ kante den auf dem Fahrweg liegenden Schnee in eine obere Schneeschicht und eine auf dem Fahrweg zunächst verweilende untere Schneeschicht. Die obere Schneeschicht gelangt dann auf den ansteigenden C-Bogen der Scharbleche und wird von diesen angehoben, wodurch der führende Radsatz eines Fahrwerks des Schienenfahrzeugs nicht entlastet wird und entglei¬ sungssicher in den Fahrschienen bleibt. Durch das Gleiten der angehobenen Schneeschicht in den C-förmig profilierten Scharblechen wird diese in eine Rotation versetzt und durch die Pfeilung der Scharbleche schraubenlinienförmig nach außen neben den Fahrweg geschleudert. Die großflächigen Scharbleche bilden eine erste Räumstufe für hohen Schnee und größere Hin¬ dernisse, während der kleinflächigere Räumschild eine zweite Räumstufe für kleinere, von der ersten Räumstufe nicht er- fasste Hindernisse bildet. Während die erste Räumstufe fest in sicherer Höhe über der Schienenoberkante montierbar ist, um hohe Kräfte auf das Untergestell übertragen zu können, kann der Betreiber des Schienenfahrzeugs die Spalthöhe durch Verstellen des Überstandes des Räumschildes einstellen, ins¬ besondere so klein einstellen, dass hinter dem Schneeräumer angeordnete Komponenten hinreichend geschützt sind. Indem es sich bei dem ein- oder mehrteiligen, beispielsweise gepfeilt angeordneten Räumschild um ein Bauteil mit einem vergleichs¬ weise geringen Anteil am Gesamtgewicht des Schneeräumers von über 400 kg handelt, kann die Einstellung der Spalthöhe auch einfach ohne maschinelle Hilfe vorgenommen werden. Der In befindlichem in driving rail vehicle the cutting edge ¬ divides the lying on the driveway of snow in an upper layer of snow and one on the track initially lingering lower layer of snow. The upper layer of snow then passes to the rising C-arm of the Scharbleche and is lifted by them, whereby the leading wheel of a chassis of the rail vehicle is not relieved and Entglei ¬ sungssicher remains in the rails. By sliding the raised layer of snow in the C-shaped shaved sheet is this set in a rotation and thrown by the sweep of Scharbleche helically outward next to the track. The large-scale Scharbleche form a first clearing stage for high snow and larger hin ¬ ments, while the smaller-scale plow blade forms a second clearing stage for smaller, not detected by the first Räumstufe obstacles. While the first Räumstufe is firmly mounted above the running surface at a safe altitude in order to transmit high forces on the base, the operator of the rail vehicle can adjust the gap height by adjusting the supernatant of the clearing blade, set so small to ¬ special is that behind the snowplow arranged components are sufficiently protected. By this is where one or more parts, for example, swept arranged plow blade to a component having a comparatively ¬ as small proportion of the total weight of the snow of over 400 kg, the adjustment of the gap height can also be carried out simply without mechanical assistance. Of the
Schneeräumer kann so befestigt werden, dass bei abgefahrenen Radreifen und bei Berücksichtigung aller möglichen Nick- und Hubbewegungen des Fahrzeugkastens die Scharbleche einen vorgebbaren Sicherheitsabstand zur Schienenoberkante haben. Damit sind die Scharbleche die meiste Zeit zu hoch angeord- net. Damit auch Komponenten wie Antenneneinrichtungen oderSnow clearers can be attached so that when worn tires and taking into account all possible pitching and lifting movements of the vehicle body, the Scharbleche have a predetermined safety distance to the rail top. This means that the Scharbleche are usually too high for the most part. So that also components such as antenna devices or
Sandungsanlagen ausreichend geschützt werden, wird der Spalt zwischen Schienenoberkante und Schneeräumer verkleinert, in¬ dem der Überstand des nach unten überstehenden Räumschildes vergrößert wird. Sanding systems are adequately protected, the gap between rail top and Schneeräumer is reduced, in ¬ the projection of the downwardly projecting plow blade is increased.
In einer bevorzugten Ausgestaltung des erfindungsgemäßen Schienenfahrzeugs ist an einer Oberkante der Scharbleche ein in Fahrtrichtung abstehender Ablenksteg angeformt. Der Ablenksteg lenkt den bis zum oberen C-Bogenende eines Scharble- ches gleitenden Schnee nach vorne um und vermindert ein Auf¬ steigen von Schnee von den Scharblechen auf eine Frontscheibe eines Führerstandes des Schienenfahrzeugs. In einer vorteilhaften Ausgestaltung des erfindungsgemäßen Schienenfahrzeugs sind die Scharbleche über mehrere, sich in Fahrtrichtung erstreckende Versteifungsrippen mit einer sich quer zur Fahrtrichtung erstreckenden Rückwand verbunden. Der Schneeräumer ist damit als in sich steifes Gebilde ausgeführt und besitzt keine definierten Energieaufnahmeeigenschaften. Eine Energieaufnahme durch den Schneeräumer könnte zu dessen Zerstörung oder Abriss führen und dadurch Hindernisse entste¬ hen lassen, deren Überfahren eine Entgleisung des Schienen- fahrzeugs bedingen könnte. In a preferred embodiment of the rail vehicle according to the invention, a deflecting web projecting in the direction of travel is integrally formed on an upper edge of the Scharbleche. The Ablenksteg directs to the upper end of a C-arm Scharble- ches snow sliding forward to and reduces an on ¬ rise of snow from the flock sheets on a windshield of a driver's cab of the rail vehicle. In an advantageous embodiment of the rail vehicle according to the invention, the Scharbleche are connected via a plurality of extending in the direction of travel stiffening ribs with a transversely extending to the direction of the rear wall. The snow remover is thus designed as a rigid structure and has no defined energy absorption properties. An energy absorption by the snowplow could lead to the destruction or demolition and thereby allow obstacles entste ¬ hen whose overrun could cause a derailment of the rail vehicle.
In einer vorteilhaften Ausführungsform umfasst das erfindungsgemäße Schienenfahrzeug frontseitig am Untergestell an¬ geordnete Pufferelemente, welche zur Aufnahme von Stoßenergie durch elastische Kompression einer Pufferfeder längs eines reversiblen, ersten Energieaufnahmeweges ausgebildet sind. Die Pufferelemente sind dabei mit dem Untergestell über De¬ formationselemente verbunden, welche zur Aufnahme von Sto߬ energie durch plastische Deformation einer Deformationsstruk- tur längs eines irreversiblen, zweiten Energieaufnahmeweges ausgebildet sind. Dabei ist der Schneeräumer derart am Unter¬ gestell befestigt, dass dessen Spitze in Fahrtrichtung hinter dem ersten und zweiten Energieaufnahmeweg liegt. Hierdurch wird bei Schienenfahrzeugen mit einem derartigen Kollisions- managementsystem der Schneeräumer aus den Energieaufnahmewegen gehalten. Trotzdem sorgt der Schneeräumer dafür, dass Kollisionspartner oder auf dem Fahrweg liegende Hindernisse von den Fahrschienen geräumt werden, ohne unter das eigene Schienenfahrzeug zu geraten und damit entgleisungskritische Situationen zu riskieren. In an advantageous embodiment, the rail vehicle according to the invention comprises at the front of the subframe ¬ ordered buffer elements, which are designed to absorb impact energy by elastic compression of a buffer spring along a reversible, first energy absorption path. The buffer elements are connected to the underframe via De ¬ formation elements, which structure for receiving impact energy by plastic deformation of a ¬ Deformationsstruk- along an irreversible energy absorption second path are formed. In this case, the snow remover is attached to the sub ¬ frame, that the tip is in the direction of travel behind the first and second energy intake path. As a result, in snow vehicles with such a collision management system, the snow clearers are kept out of the energy intake paths. Nevertheless, the snowplower ensures that collision partners or obstacles lying on the roadway are cleared of the rails, without getting under the own rail vehicle and thus risking derailment critical situations.
Vorzugsweise umfasst das erfindungsgemäße Schienenfahrzeug seitlich am Untergestell angeordnete Anhebestellen für eine Hebeeinrichtung, wobei die Scharbleche des Schneeräumers ei- nen derart stumpfen Spitzenwinkel einschließen, dass seitli¬ che Außenkanten der Scharbleche in Fahrtrichtung hinter den Anhebestellen enden. Damit muss der Schneeräumer nicht abgebaut werden, wenn das Schienenfahrzeug - beispielsweise zum Ein- oder Aufgleisen - anzuheben ist. Entgegen den bekannten spitzwinkligen Pfeilungen von Schneeräumern, wird der Spitzenwinkel vorzugsweise stumpf ausgeführt, beispielsweise zwi¬ schen 100° und 120°, um die Spitze des Schneeräumers aus dem Energieaufnahmeweg heraus zu halten. Preferably, the rail vehicle of the invention the side covers arranged on the underframe lifting points for a lifting device, wherein the blade sheets of the snow egg NEN include such blunt tip angle that seitli ¬ che outer edges of the blade sheet in the direction of travel terminate behind the lifting points. Thus, the snowplower does not have to be dismantled when the rail vehicle - for example On or Rerailing - lift is. Contrary to the known acute Pfeilungen of snow plows, the apex angle is preferably carried out blunt, for example, Zvi ¬ rule 100 ° and 120 °, in order to keep the tip of the snow from the Energieaufnahmeweg out.
In einer vorteilhaften Ausführungsform umfasst das erfindungsgemäße Schienenfahrzeug eine hinter dem Schneeräumer an¬ geordnete Antenneneinrichtung, wobei an der Rückwand des Schneeräumers eine Konsole angeordnet ist, welche die Anten¬ neneinrichtung von oben abdeckt. Durch die integrierte Konso¬ le wird ein zusätzlicher Schutz der Antenneneinrichtung vor äußeren mechanischen Beschädigungen geboten. In einer bevorzugten Ausgestaltung umfasst das erfindungsgemäße Schienenfahrzeug ein frontseitig am Untergestell an¬ geordnetes Kupplungselement, wobei der Schneeräumer im Be¬ reich der Spitze eine Ausnehmung aufweist, durch die das Kupplungselement hindurch geführt ist. Die Ausnehmung kann dadurch gebildet sein, dass mittig angeordnete Innenkanten der Scharbleche nicht aneinander stoßen, oder dass mittig auf Stoß angeordnete Scharbleche einen beispielsweise rechtecki¬ gen Ausschnitt aufweisen. So kann bei montiertem Schneeräumer ein als Schraubenkupplung ausgebildetes Kupplungselement nach hinten durchfedern oder der Kupplungskopf eines als Mittel¬ pufferkupplung ausgebildeten Kupplungselements getauscht werden . In an advantageous embodiment, the rail vehicle of the invention comprises a behind the snowplow to ¬ parent antenna device, wherein a console is arranged on the rear wall of the snow covering the transformants ¬ neneinrichtung from above. The integrated Konso ¬ le is offered an additional protection of the antenna device from external mechanical damage. In a preferred embodiment, the rail vehicle according to the invention comprises a coupling element arranged on the front side on the underframe, wherein the snow clearer has a recess in the region of the point through which the coupling element is guided. The recess may be formed in that center-arranged inner edges of the Scharbleche not abut each other, or that centrally arranged on impact Scharbleche have an example rechtecki ¬ gen cutout. Thus, in the assembled snowplow can designed as a screw coupling clutch member by spring back or the head of a clutch designed as a central buffer coupling ¬ coupling element to be replaced.
