Description

Gleisbaumaschine  track-laying machine
[01] Die Erfindung betrifft eine Gleisbaumaschine mit einem durch Schienen- fahrwerke auf einem Gleis verfahrbaren Maschinenrahmen und einem mit einer Anzahl von Antrieben verbundenen Energieversorgungssystem, das sich aus einem Verbrennungsmotor und einem wenigstens eine Hydraulikpumpe aufweisenden Hydraulikantriebsystem zusammensetzt.  [01] The invention relates to a track construction machine having a machine frame that can be moved on a track by railroad tracks and an energy supply system connected to a number of drives, which is composed of an internal combustion engine and a hydraulic drive system having at least one hydraulic pump.
[02] Der Verbrennungsmotor einer Gleisbaumaschine läuft in vielen Fällen auch während einer längeren Unterbrechung eines Arbeitseinsatzes bei voller Leistung. Dies führt zu hohem Kraftstoffverbrauch sowie zu einem erhöhten Wartungsaufwand.  The internal combustion engine of a track construction machine runs in many cases, even during a longer interruption of a labor input at full power. This leads to high fuel consumption and increased maintenance.
[03] Die Aufgabe der vorliegenden Erfindung liegt nun in der Schaffung einer  [03] The object of the present invention is now to provide a
Gleisbaumaschine der eingangs genannten Art, mit der eine Verbesserung der für den Maschinenbetrieb erforderlichen Energiebilanz möglich ist.  Track construction machine of the type mentioned, with the improvement of the energy balance required for the machine operation is possible.
[04] Diese Aufgabe wird erfindungsgemäß mit einer.Gleisbaumaschine der eingangs genannten Art durch folgende Merkmale gelöst:  [04] This object is achieved according to the invention with a track construction machine of the type mentioned at the outset by the following features:
[05] a) der Verbrennungsmotor ist durch eine Antriebswelle mechanisch mit einer elektrischen Generator/Motoreinheit verbunden,  [05] a) the internal combustion engine is mechanically connected to an electric generator / motor unit by a drive shaft,
[06] b) die Generator/Motoreinheit ist durch eine Antriebsvorrichtung mit der Hydraulikpumpe verbunden, [07] c) ein Stromspeicher ist durch eine elektrische Versorgungsleitung mit der Generator/Motoreinheit sowie mit den elektrisch beaufschlagbaren Antrieben verbunden. [06] b) the generator / motor unit is connected to the hydraulic pump by a drive device, [07] c) a power storage is connected by an electrical supply line with the generator / motor unit and with the electrically actuated drives.
[08] Durch diese Merkmalskombination ist es möglich, diverse Antriebe auf der Gleisbaumaschine hauptsächlich elektrisch zu versorgen. Soweit hydraulische Antriebe erforderlich sind, können die notwendigen Hydraulikpumpen über die vom Stromspeicher gespeiste Generator/Motoreinheit angetrieben werden. Dadurch kann unter Vermeidung der zum Stand der Technik bereits angeführten Nachteile auch mit einem leistungsmäßig reduzierten Verbrennungsmotor das Auslangen gefunden werden.  [08] This combination of features makes it possible to mainly supply various drives on the track-laying machine electrically. As far as hydraulic drives are required, the necessary hydraulic pumps can be powered by the powered by the power storage generator / motor unit. As a result, while avoiding the drawbacks already mentioned in the prior art, the shortcomings can also be found with a reduced-performance internal combustion engine.
[09] Weitere Vorteile der Erfindung ergeben sich aus dem Unteranspruch und der Zeichnungsbeschreibung.  [09] Further advantages of the invention will become apparent from the dependent claim and the drawing description.
[10] Im Folgenden wird die Erfindung anhand eines in der Zeichnung dargestellten Ausführungsbeispieles näher beschrieben.  [10] In the following the invention will be described in more detail with reference to an embodiment shown in the drawing.
[11] In Fig. 1 ist eine zum Unterstopfen eines Gleises ausgebildete Gleisbaumaschine in Seitenansicht, in Fig. 2 schematisch ein Schienenfahrwerk, eine Antriebseinheit und ein Energieversorgungssystem in Draufsicht dargestellt.  FIG. 1 shows a side view of a track construction machine designed for plugging a track, and FIG. 2 shows a schematic view of a rail drive, a drive unit and an energy supply system in plan view.
[12] Eine Gleisbaumaschine 1 ist mit einem durch Schienenfahrwerke 2 auf einem Gleis 3 verfahrbaren Maschinenrahmen 4 und einem mit einer Anzahl von verschiedenen Antrieben 5 verbundenen Energieversorgungssystem 6 ausgestattet. Dieses setzt sich aus einem Verbrennungsmotor 7, einem Hydraulikpumpen 8 aufweisenden Hydraulikantriebsystem 9 sowie zwei Generator/Motoreinheiten 10 zusammen. [12] A track construction machine 1 is equipped with a machine frame 4 movable by track gears 2 on a track 3 and an energy supply system 6 connected to a number of different drives 5. This is made up of an internal combustion engine 7, a hydraulic pump 8 having hydraulic drive system 9 and two generator / motor units 10 together.
[ 3] Ein mit zahlreichen Antrieben 5 ausgestattetes Stopfaggregat 13 sowie ein durch hydraulische Antriebe 5 verstellbares Gleishebeaggregat 14 sind für die Gleislagekorrektur vorgesehen. Verschiedene weitere elektrische Antriebe 5 für einen Luftkompressor 15, eine Klimaanlage 16 sind hier nur beispielhaft angeführt.  A equipped with numerous drives 5 Stopfaggregat 13 and an adjustable by hydraulic drives 5 track lift unit 14 are provided for the track position correction. Various other electric drives 5 for an air compressor 15, an air conditioner 16 are given here by way of example only.
[14] Der Verbrennungsmotor 7 ist durch eine Antriebswelle 17 und über eine hier als das Verteilergetriebe 18 ausgebildete Antriebsvorrichtung 19 mechanisch mit zwei elektrischen Generator/Motoreinheiten 10 verbunden.  The internal combustion engine 7 is mechanically connected to two electric generator / motor units 10 through a drive shaft 17 and via a drive device 19 designed here as the transfer case 18.
[15] Jede Generator/Motoreinheit 10 ist über die Antriebsvorrichtung 19 mit den Hydraulikpumpen 8 verbunden.  [15] Each generator / motor unit 10 is connected to the hydraulic pumps 8 via the drive device 19.
[16] Ein Stromspeicher 20 ist durch eine elektrische Versorgungsleitung 21 mit den Generator/Motoreinheiten 10, mit Stromrichtern 12 sowie mit den elektrisch beaufschlagbaren Antrieben 5 verbunden. Dem Schienenfahr- werk 2 ist eine mit dem Stromspeicher 20 in Verbindung stehende Generator/Motoreinheit 10 als Fahrantrieb zugeordnet.  A power storage 20 is connected by an electrical supply line 21 with the generator / motor units 10, with power converters 12 and with the electrically actuated drives 5. The Schienenfahrwerk 2 is associated with the power storage 20 in conjunction generator / motor unit 10 is assigned as a drive.
[17] Im Arbeitseinsatz treibt der Verbrennungsmotor 7 über das Verteilergetriebe 18 beide Motor/Generatoreinheiten 10 mit jeweils 150 KW Nennleistung an. Der Verbrennungsmotor 7 ist mit einem Freilauf (oder Kupplung) 22 ausgestattet, damit die Gleisba maschine 1 auch ohne Verbrennungsmotor 7 arbeiten kann. Bei gestartetem Verbrennungsmotor 7 wir- ken die Generator/Motoreinheiten 10 als Generatoren, die mit 300 kW Ladeleistung den Stromspeicher 20 aufladen und/oder den benötigten Strom für die beiden als Fahrantrieb dienenden Generator/Motoreinheiten 10 im Überstell- bzw. Arbeitsmodus liefern. Außerdem wird eine Aufrechterhaltung des hydraulischen Systemdruckes bei abgestelltem Verbrennungsmotor 7 gewährleistet, indem eine Hydraulikpumpe 8 durch eine Generator/Motoreinheit 10 angetrieben wird. Bei Aktivierung von hydraulischen Antrieben 5 erfolgt deren Energieversorgung durch die Hydraulikpumpen 8. [17] During operation, the internal combustion engine 7 drives, via the transfer case 18, both motor / generator units 10, each with a rated power of 150 KW. The internal combustion engine 7 is equipped with a freewheel (or clutch) 22, so that the Gleisba machine 1 can work without an internal combustion engine 7. When the internal combustion engine 7 is started, ken the generator / motor units 10 as generators that charge the power storage device 20 with 300 kW charging power and / or provide the required power for the two serving as a drive generator / motor units 10 in the transfer or working mode. In addition, a maintenance of the hydraulic system pressure is ensured with the engine 7 off by a hydraulic pump 8 is driven by a generator / motor unit 10. When activating hydraulic drives 5, their power supply is provided by the hydraulic pumps 8.
[ 8] Der Lithium-Ionen-Polymer-Akku hat hier als Beispiel eine Leistung von  The lithium-ion polymer battery has an example of a performance of
200 kW/h und lässt sich durch die vom Verbrennungsmotor 7 betriebenen Generator/Motoreinheiten 10 bereits innerhalb von etwa 25 Minuten auf 80% der Speicherkapazität aufladen. Das System ist so ausgelegt dass auch die diversen elektrischen Antriebe 5 von Nebenaggregaten mittels Hochspannung versorgbar sind. Damit ist für längere Zeit eine Versorgung der Antriebe 5 möglich, ohne dass dazu der Verbrennungsmotor 7 gestartet werden muss. Die Verwendung des Verbrennungsmotor 7 im Lastbetrieb kann in vorteilhafter Weise auf den Arbeitseinsatz beschränkt werden. Bei vollem Stromspeicher 20 kann dieser auch im Arbeitseinsatz streckenweise die Energieversorgung übernehmen.  200 kW / h and can be charged by the powered by the engine 7 generator / motor units 10 already within about 25 minutes to 80% of the storage capacity. The system is designed so that the various electric drives 5 of ancillaries can be supplied by means of high voltage. Thus, a supply of the drives 5 is possible for a long time without the need to start the engine 7. The use of the internal combustion engine 7 during load operation can advantageously be limited to the labor input. When the power storage device 20 is full, it can also take over the power supply in some cases during work.
