Description
Anordnung für die Belüftung von Bremswiderständen und Ölkühlern auf Triebfahrzeugen, insbesondere Schienentriebfahrzeugen Die Erfindung betrifft eine Anordnung für die Belüftung von Bremswiderständen und Ölkühlern auf Triebfahrzeugen, insbesondere Schienentriebfahrzeugen. Hierbei ist es ohne Bedeutung, ob es sich um ein Wechselstromtriebfahrzeug mit Widerstandsbremse und Transformator oder um ein dieselelektrisches Triebfahrzeug handelt, bei dem der Ölkühler die Temperatur des Hauptdieselmotors beeinflußt.Arrangement for the ventilation of braking resistors and oil coolers Locomotives, in particular rail locomotives The invention relates to a Arrangement for the ventilation of braking resistors and oil coolers on locomotives, especially rail locomotives. It is irrelevant whether it is around an AC traction vehicle with a drag brake and transformer or around a diesel-electric traction vehicle in which the oil cooler controls the temperature of the main diesel engine.
Bei der bisherigen Ausführung fremdbelüfteter elektrischer Bremswiderstände in elektrischen Triebfahrzeugen macht sich besonders die schlechte Ausnutzung des den Bremswiderstandslüfter antreibenden Motors störend bemerkbar. Infolge der geringen Einschaltdauer dieses Motors treten verhältnismäßig bald bei den rotierenden Teilen Lagerschäden auf, die auf die auf den Lokomotivkasten wirkenden Beschleunigungskräfte zurückzuführen sind.In the previous version, force-ventilated electrical braking resistors in electric traction vehicles, the poor utilization of the noticeably disturbing the motor driving the braking resistor fan. As a result of the low The duty cycle of this motor occurs relatively soon for the rotating parts Bearing damage on the acceleration forces acting on the locomotive body are due.
Um die Lagerschäden gering zu halten, hat man bereits versucht, axial verspannte Lager zu verwenden, doch sind die Ergebnisse mit solchen Lagern noch nicht befriedigend.In order to keep the bearing damage low, attempts have already been made to axially Use braced bearings, but the results with such bearings are still not satisfying.
Erfindungsgemäß werden bei der eingangs genannten Anordnung für die Belüftung von Bremswiderständen und Ölkühlern der Ölkühler und der Bremswiderstand in je zwei gleiche Elemente aufgeteilt und jeweils ein Bremswiderstandselement und ein Ölkühlerelement mit einem gemeinsamen Lüfter zu einer Baugruppe vereinigt. Damit ergibt sich bei gleichem Aufwand an Lüftern infolge des Dauerbetriebes die Vermeidung von Lagerschäden am Lüftermotor und eine Einsparung des auf Triebfahrzeugen sehr knappen Raumes.According to the invention are in the aforementioned arrangement for Ventilation of braking resistors and oil coolers, the oil cooler and the braking resistor divided into two equal elements and one braking resistor element each and an oil cooler element combined with a common fan to form an assembly. In order to This results in avoidance with the same expenditure on fans as a result of the continuous operation from bearing damage to the fan motor and a saving on traction vehicles tight space.
Hierbei ist es vorteilhaft, in an sich bekannter Weise die Kühlluft jeder Baugruppe aus dem Maschinenraum anzusaugen und aus den Dachaufbauten auszublasen. In ebenfalls vorteilhafter Weise werden, wie bekannt, unter Verwendung von Lüftern mit vorzugsweise axialer Luftführung stehende Baugruppen gebildet, bei denen durch Wahl der Motorklemmenspannung in an sich bekannter Weise die Lüfterleistung dem jeweiligen Kühlluftbedarf angepaßt ist.It is advantageous here to use the cooling air in a manner known per se sucking each assembly out of the engine room and blowing it out of the roof structure. Also advantageously, as is known, using fans with preferably axial air ducting standing assemblies, in which by Choice of the motor terminal voltage in a manner known per se, the fan power is adapted to the respective cooling air requirement.
Die Erfindung wird an Hand eines Ausführungsbeispiels beschrieben.The invention is described using an exemplary embodiment.
Fig. 1 zeigt den Längsschnitt und Fig. 2 den Querschnitt durch den Maschinenraum einer elektrischen Wechselstromlokomotive.Fig. 1 shows the longitudinal section and Fig. 2 shows the cross section through the Engine room of an AC electric locomotive.
In diesen Figuren ist mit 1 der Transformatör bezeichnet, an dessen beiden Seiten Baugruppen angeordnet sind, die je aus einem Lüfter 2, einem Ölkühlerelement 3 und einem Bremswiderstandselement 4 bestehen. Jede der Lüftergruppen ist über hier nicht dargestellte, an sich bekannte, vorzugsweise als Faltenbälge ausgebildete bewegliche Kanäle mit den in den Dachaufbauten befindlichen Abluftkanälen verbunden.In these figures, 1 denotes the transformer, on whose Both sides assemblies are arranged, each consisting of a fan 2, an oil cooler element 3 and a braking resistor element 4 exist. Each of the fan groups is over Not shown here, known per se, preferably designed as bellows movable ducts connected to the exhaust ducts located in the roof structures.
Die Kühlluft wird aus dem Maschinenraum durch das ölkühlerelement 3 hindurch angesaugt und, nachdem auch noch das Bremswiderstandselement 4 gekühlt wurde, aus den Dachaufbauten wieder ausgeblasen. Das ölkühlerelement 3 ist in diesem Falle seitlich an das Lüfteraggregat angebaut, so daß der Luftstrom zwischen ölkühlerelement 3 und Lüfter 2 rechtwinklig umgelenkt werden muß. Das Bremswiderstandselement 4 ist, wie bekannt, etwa koaxial zum Lüfter 2 angeordnet. Unter dem Lüfter 2 sind verschließbare Jalousien 5 angeordnet, durch die beim Bremsen unter Umgehung des Ölkühlerelementes 3 Luft angesogen werden kann, wodurch bei gegebener Lüfterleistung infolge Herabsetzung des Strömungswiderstandes die das Bremswiderstandselement 4 kühlende Luftmenge vergrößert wird. Die verschließbare Jalousie 5 soll während des ziehenden Betriebes des Fahrzeuges geschlossen bleiben, um das Eindringen von Fremdkörpern, insbesondere das Eindringen von Treibsand oder Flugschnee in den Maschinenraum möglichst weitgehend zu verhindern.The cooling air is drawn from the engine room through the oil cooler element 3 sucked through and, after the braking resistor element 4 also cooled was blown out of the roof structure again. The oil cooler element 3 is in this Trap attached to the side of the fan unit so that the air flow between the oil cooler element 3 and fan 2 must be deflected at right angles. The braking resistor element 4 is, as is known, arranged approximately coaxially to the fan 2. Under the fan 2 are closable blinds 5 arranged through which when braking, bypassing the Oil cooler element 3 air can be sucked in, whereby with a given fan power as a result of a reduction in the flow resistance, the braking resistor element 4 cooling air volume is increased. The closable blind 5 should during the during towing operations of the vehicle remain closed to prevent the ingress of foreign bodies, in particular the penetration of quicksand or drifting snow into the engine room if possible largely to prevent.
Durch Anpassen der Klemmenspannung der Lüftermotoren an den jeweiligen Luftbedarf wird in vorteilhafter Weise der Energiebedarf in wirtschaftlichen Grenzen gehalten. Zur Ausnutzung der Über- und Unterdruckseite von Axiallüftern liegt das Bremswiderstandselement 4 auf der Überdruckseite und das Ölkühlerelement 3 auf der Unterdruckseite des Lüfters 2.By adapting the terminal voltage of the fan motors to the respective Air requirement is advantageously the energy requirement within economic limits held. To utilize the positive and negative pressure side of axial fans this is Braking resistor element 4 on the overpressure side and the Oil cooler element 3 on the negative pressure side of the fan 2.
Der Platzbedarf einer solchen Anordnung ist durch die Teilung von Ölkühler und Bremswiderstand in je zwei gleiche Elemente kleiner als der bisher vom Ölkühler, Ölkühlerlüfter, Bremswiderstand und Bremswiderstandslüfter beanspruchte Raum, so daß es bei gleichem Platzbedarf möglich ist, eine größere Bremsleistung in der Lokomotive unterzubringen als bisher.The space required for such an arrangement is due to the division of Oil cooler and braking resistor in two identical elements each smaller than the previous one stressed by the oil cooler, oil cooler fan, braking resistor and braking resistor fan Space, so that it is possible with the same space requirement, a greater braking power to be accommodated in the locomotive than before.
