Description
Die Erfindung betrifft ein Schienentriebfahrzeug, insbesondere eine Lokomotive, mit einem dieselhydraulischen Antrieb, mit einem Wagenkasten oder Rahmen zur Aufnahme eines Antriebsmotors, eines Getriebes und von Komponenten für die Kühlung von Fluiden, wie Motoröl, Getriebefluid und Fluid einer Klimaanlage, welche Komponenten wenigstens einen Kühler, Pumpen und Verbindungsleitungen für das jeweilige Fluid umfassen und auf dem Fahrzeug von einer Gehäuseabdeckung umgeben sind.The invention relates to a rail locomotive, in particular a locomotive, with a diesel-hydraulic drive, with a car body or frame for mounting a drive motor, a transmission and components for cooling fluids, such as engine oil, transmission fluid and air conditioning fluid, which components at least one cooler, pumps and connecting lines for the respective fluid include and are surrounded on the vehicle by a housing cover.
Es ist bekannt, daß Schienentriebfahrzeuge mit von Verbrennungsmaschinen gebildeten Antriebsmotoren ausgerüstet sind und zur Abführung der beim Betrieb der Antriebsmotoren freigesetzten Abwärme Kühleinrichtungen aufweisen. Ferner ist bekannt, daß beim Einsatz von hydraulischen Drehmomentwandlern und Getrieben, wie sie vornehmlich bei dieselhydraulisch betriebenen Schienentriebfahrzeugen vorgesehen sind, ebenfalls Wärme freigesetzt wird, die abgeführt werden muß, um den störungsfreien Betrieb zu gewährleisten und mögliche thermisch bedingte Schäden zu vermeiden.It is known that railcars with internal combustion engines Drive motors are equipped and for the removal of the drive motors during operation have released waste heat cooling devices. It is also known that when using hydraulic torque converters and gearboxes, as they primarily are provided for diesel-hydraulic rail vehicles, heat is also released, which must be dissipated to ensure trouble-free Ensure operation and avoid possible thermal damage.
Um diesen Anforderungen zu entsprechen, ist allgemein verbreitet, die betreffenden Fahrzeuge mit Kühlaggregaten auszurüsten, in welchen die aus den jeweiligen Wärmequellen herrührende Abwärme mit Hilfe von Wärmetauschern an die Umgebung abgegeben wird.In order to meet these requirements, it is widely used that Equip vehicles with cooling units, in which the from the respective heat sources any waste heat is released to the environment with the help of heat exchangers becomes.
Bei modernen Schienentriebfahrzeugen sind die Kühlaggregate für das Kühlwasser sowie gegebenenfalls bei hydraulischer Leitungsübertragung für das Hydraulikfluid des hydraulischen Drehmomentwandlers bzw. Getriebes auf dem Schienentriebfahrzeug jeweils an geeigneter Stelle plaziert, das heißt dort, wo verfügbarer Raum ist. Die Einbindung dieser Aggregate erfolgt üblicherweise sukzessive im Zuge der Fertigung des Schienentriebfahrzeuges, wobei ein besonderes Problem, das auch im späteren Betrieb zu Störungen führen kann, aus der Verbindung der Fluidleitungen mit den betreffenden Aggregaten resultiert.In modern rail traction vehicles, the cooling units are for the cooling water and optionally with hydraulic line transmission for the hydraulic fluid of the hydraulic torque converter or transmission on the rail engine placed in a suitable place, i.e. where there is available space. The integration these units usually take place successively in the course of the manufacture of the Rail locomotive, which is a particular problem that also in later operation can lead to malfunctions from the connection of the fluid lines with the concerned Aggregates results.
Diese Aggregate, nämlich sowohl die Antriebsmaschine und das Getriebe als auch die zugeordneten Kühler sind jeweils elastisch gelagert um so die Übertragung von betriebsbedingten Schwingungen auf den Fahrzeugrahmen nach Möglichkeit zu vermeiden. Bei der Einbindung der hydraulischen Pumpen für die Umwälzung des Hydraulikfluids beziehungsweise des Kühlwassers in den jeweiligen Kreislauf der Kühleinrichtung beziehungsweise der Hilfseinrichtungen werden im allgemeinen zur Aufnahme von betriebsbedingten Schwingungen der betreffenden Bauteile sowie zur Vermeidung von ansonsten erforderlichen Anpassungsarbeiten Schlauchverbindungen verwendet. Diese Schlauchleitungen und Verbinder sowie gegebenenfalls Rohrleitungen sowie die Umwälzpumpen werden lose mitgeliefert und sind vom Motorhersteller beziehungsweise vom Fahrzeughersteller jeweils zu montieren.These units, namely both the engine and the transmission as well assigned coolers are each elastically mounted so that the transfer of operational Avoid vibrations on the vehicle frame if possible. When integrating the hydraulic pumps for the circulation of the hydraulic fluid or the cooling water in the respective circuit of the cooling device or the auxiliary facilities are generally for inclusion of operational vibrations of the relevant components and to avoid them hose connections are used for otherwise required adjustment work. These hose lines and connectors and, if necessary, pipelines and the Circulation pumps are supplied loose and are from the motor manufacturer respectively to be assembled by the vehicle manufacturer.
Bei der Montage der ebenfalls zum Lieferumfang der Kühlanordnung gehörigen Umwälzpumpen sind zeitraubende Anpassungsarbeiten, wie mechanische Bearbeitung und Ausrichtung der Komponenten, unvermeidlich. Dabei sind Montagefehler und sonstige Abweichungen von bestehenden Vorgaben nie völlig auszuschließen, was das Risiko späterer Störungen in sich birgt. Als wesentlicher Punkt kann die Dichtheits- und Druckprüfung erst nach der erfolgten Montage erfolgen, was im Falle auftretender Störungen zu unerwünschtem Lieferverzug führen kann.When installing the circulation pumps that are also included in the scope of delivery of the cooling arrangement are time-consuming adjustments, such as mechanical processing and alignment of the components, inevitable. There are assembly errors and other deviations from existing specifications can never be completely excluded, what carries the risk of later disruptions. As an essential point, the tightness and pressure test only take place after assembly, which occurs in the event of Disruptions can lead to undesired delays in delivery.
Eine Komplettmontage der einzelnen Kommponenten der Kühleinrichtung einschließlich der zugehörigen Abnahmeprüfungen durch deren Lieferanten ist, wie gezeigt, aufgrund der bislang üblichen Anordnungskonzeption der einzelnen Komponenten auf den Schienentriebfahrzeugen nicht möglich, so daß sich die Ursachen späterer Störfälle infolge dieser montagebedingten Verzahnung der Fertigung sich schwer und nur mit unverhältnismäßigem Aufwand aufklären lassen.A complete assembly of the individual components of the cooling device including the associated acceptance tests by their suppliers are due, as shown the previously usual arrangement of the individual components on the Rail locomotives are not possible, so that the causes of later accidents due to this assembly-related interlocking of production difficult and only with clarify disproportionate effort.

Um einerseits die Verantwortlichkeiten klar zu definieren und andererseits den Fertigungsablauf bei der Herstellung des Schienentriebfahrzeugs zu verkürzen, sind gemäß einer weiteren Verbesserung der Erfindung die Leitungswege und Volumina der zur Montage bereit stehenden Kühlanordnung mit dem Hydraulikfluid für die Hydrostatikantriebe bereits komplett befüllt und erprobt.To clearly define the responsibilities on the one hand and the production process on the other Shorten in the manufacture of the rail locomotive are according to a further improvement of the invention, the routes and volumes of the Assembled cooling arrangement with the hydraulic fluid for the hydrostatic drives already completely filled and tested.
Zur Umwälzung des Fluids dient in vorteilhafter Weiterbildung der Erfindung eine Tandempumpe oder Dreifachpumpe, deren Antrieb durch den fahrzeugeigenen Antriebsmotor erfolgt. Demgemäß ist vorgesehen, daß der Antrieb mittels einer Gelenkwelle erfolgt, welche die gegebenenfalls auftretenden Bautoleranzen sowie Differenzbewegungen im Betrieb ausgleicht.In an advantageous further development of the invention, a tandem pump is used to circulate the fluid or triple pump, which is driven by the vehicle's own drive motor he follows.

Dabei ist jedoch zusätzlich ein zwischen dem Gebläse und dem Kühler angeordneter Kanal mit einem Abzweig vorgesehen, über welchen ein Teilluftstrom zur Belüftung des Maschinenraums entnehmbar ist, so daß eine besondere, das heißt zusätzliche, Maschinenraumbelüftung entfallen kann, wobei der Teilluftstrom einstellbar ist.In a manner known per se, a blower is also advantageously provided, which is arranged below the cooler and the waste heat after the cooling arrangement leads outside.
