Description
Die vorliegende Erfindung betrifft ein Verfahren zum Ansteuern einer Arbeitsmaschine mit einem Hybridsystem gemäß der im Oberbegriff des Patentanspruches 1 näher definierten Art. Ferner betrifft die Erfindung eine Arbeitsmaschine zum Anwenden des Verfahrens.The present invention relates to a method for driving a work machine with a hybrid system according to the closer defined in the preamble of
Bei Arbeitsmaschinen, insbesondere bei Baumaschinen tritt während des Arbeitsbetriebes ein häufiges Reversieren auf. Eine Möglichkeit, eine so genannte Power Shuttle Reversierung bei Arbeitsmaschinen durchzuführen, ist durch eine Lastschaltung im Getriebe von einer Kupplung, die den Vorwärtsgängen zugeordnet ist, auf eine Kupplung, die den Rückwärtsgängen zugeordnet ist, mittels einer Überschneidungsschaltung zu wechseln. Diese bekannte Verfahrensweise setzt jedoch ein Wendegetriebe zum Reversieren der Fahrtrichtung bei der Arbeitsmaschine zwingend voraus.In working machines, especially in construction machines, frequent reversing occurs during operation. One way to perform a so-called power shuttle reversing work machines, is to be changed by a load circuit in the transmission of a clutch that is assigned to the forward gears to a clutch that is assigned to the reverse gears by means of an overlapping circuit. However, this known procedure requires a reverse gear for reversing the direction of travel in the work machine compelling.
Der vorliegenden Erfindung liegt die Aufgabe zu Grunde, ein Verfahren zum Ansteuern einer Arbeitsmaschine ohne Wendegetriebe vorzuschlagen, mit dem eine Reversierung der Fahrtrichtung auf einfachste Weise ermöglicht wird.The present invention is based on the object to propose a method for driving a machine without reverse gear, with the reversal of the direction of travel is made possible in the simplest way.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruches 1 bzw. 10 gelöst, wobei sich vorteilhafte Ausgestaltungen aus den Unteransprüchen und der Beschreibung sowie den Zeichnungen ergeben.This object is achieved by the features of
Es wird ein Verfahren zum Ansteuern einer Arbeitsmaschine mit einem Hybridsystem mit zumindest einem Primär- und einem Sekundärantrieb sowie mit zumindest einem Energiespeicher vorgeschlagen, wobei eine Reversierung der Fahrtrichtung über das Hybridsystem durchgeführt wird.It is proposed a method for driving a work machine with a hybrid system with at least one primary and a secondary drive and with at least one energy storage, wherein a reversal of the direction of travel is performed via the hybrid system.
Auf vorteilhafter Weise ist es möglich die Fahrtrichtungsumkehr bei der Arbeitsmaschine über das Hybridsystem ohne die Verwendung eines Wendekupplungssatzes und eines Rückwärtsganges durchzuführen.Advantageously, it is possible to reverse the direction of travel of the work machine via the hybrid system without the use of a reversing clutch set and a reverse gear.
Gemäß einer vorteilhaften Weiterbildung der Erfindung kann dies durch eine vom Betriebsmodus bzw. Fahrmodus der Arbeitsmaschine abhängige Kombination aus Antrieb über Primär- und/oder Sekundärantrieb durchgeführt werden. Üblicherweise umfasst die Arbeitsmaschine als Primärantrieb zum Beispiel einen Verbrennungsmotor und als Sekundärantrieb eine mit zumindest einem Energiespeicher gekoppelte elektrische Maschine. Durch das Hybridsystem kann die Drehrichtungsumkehr somit auf einfachste Weise durchgeführt werden. Besonders vorteilhaft ist es, wenn die Arbeitsmaschine als Getriebe ein stufenloses Getriebe umfasst, dessen Übersetzungen auch beim rein elektrischen Antrieb genutzt werden können.According to an advantageous development of the invention, this can be carried out by a mode of operation or driving mode of the working machine dependent combination of drive via primary and / or secondary drive. Usually, the working machine comprises, for example, an internal combustion engine as the primary drive and, as the secondary drive, an electric machine coupled to at least one energy store. By the hybrid system, the reversal of rotation can thus be carried out in the simplest way. It is particularly advantageous if the working machine comprises as a gearbox a continuously variable transmission whose translations can also be used in a purely electric drive.
Die der Erfindung zu Grunde liegende Aufgabe wird auch durch eine Arbeitsmaschine zum Anwenden bzw. Durchführen des erfindungsgemäßen Verfahrens gelöst. Die vorgeschlagene Arbeitsmaschine umfasst einen Antriebsstrang mit einem Hybridsystem mit einem als Verbrennungsmotor ausgeführten Primärantrieb, der vom Abtrieb über zum Beispiel eine Trennkupplung entkoppelbar ist, um beispielsweise einen angeschlossenen Nebenabtrieb oder eine Arbeitshydraulik auch im Stillstand oder bei rein elektrischem Antrieb der Arbeitsmaschine anzutreiben. Darüber hinaus umfasst der Antriebsstrang als Hybridsystem eine elektrische Maschine, die mit einem Energiespeicher gekoppelt ist, der elektrisch, hydraulisch oder auch mechanisch ausgeführt sein kann. Ferner ist ein der elektrischen Maschine nachgeschaltetes vorzugsweise stufenloses Getriebe CVT vorgesehen, welches mit dem Abtrieb verbunden ist. Das Hybridsystem ist zum Beispiel als Parallelhybrid ausgeführt. Über das Hybridsystem kann neben dem Betrieb der Arbeitshydraulik auch ein Antrieb in beide Fahrtrichtungen der Arbeitsmaschine erfolgen.The object underlying the invention is also achieved by a working machine for applying or carrying out the method according to the invention. The proposed work machine comprises a drive train with a hybrid system with a primary drive designed as an internal combustion engine, which can be decoupled from the output via, for example, a disconnect clutch in order to drive, for example, a connected power take-off or a working hydraulics even when the work machine is at a standstill or with purely electric drive. In addition, the drive train as a hybrid system comprises an electric machine which is coupled to an energy store, which may be designed electrically, hydraulically or mechanically. Further, a downstream of the electric machine preferably continuously variable transmission CVT is provided, which is connected to the output. The hybrid system is designed, for example, as a parallel hybrid. About the hybrid system can be done in both directions of the machine in addition to the operation of the work hydraulics and a drive.
Nachfolgend wird die vorliegende Erfindung anhand der Zeichnungen weiter erläutert. Es zeigen:Hereinafter, the present invention will be further explained with reference to the drawings. Show it:
In
Der Antriebsstrang
Mit dem vorgeschlagenen Verfahren zum Ansteuern der Arbeitsmaschine ist es möglich, die Reversierung der Fahrtrichtung über das Hybridsystem durchzuführen. Der Antrieb und/oder das Abbremsen in jede Fahrtrichtung kann in Abhängigkeit des jeweiligen Betriebsmodus der Arbeitsmaschine durch das Hybridsystem mit dem Verbrennungsmotor VM und/oder mit der elektrischen Maschine EM durchgeführt werden.With the proposed method for driving the work machine, it is possible to perform the reversal of the direction of travel via the hybrid system. The drive and / or the braking in each direction of travel can be performed by the hybrid system with the internal combustion engine VM and / or with the electric machine EM, depending on the respective operating mode of the working machine.
In
Bei der erfindungsgemäß vorgeschlagenen Arbeitsmaschine wird die elektrische Maschine EM vorzugsweise zwischen dem Verbrennungsmotor VM und dem stufenlosen Getriebe CVT angeordnet, sodass die Übersetzung des Getriebes CVT auch für einen rein elektrischen Antrieb genutzt wird. Alternativ kann die elektrische Maschine EM auch getriebeausgangsseitig angeordnet werden. Dabei ergeben sich allerdings höhere Drehmomentanforderungen für den elektrischen Antrieb. Die vorgesehene Trennkupplung K0 ermöglicht die Entkopplung von Verbrennungsmotor VM und elektrischer Maschine EM, so dass ein rein elektrischer Antrieb möglich ist.In the work machine proposed according to the invention, the electric machine EM is preferably arranged between the internal combustion engine VM and the continuously variable transmission CVT, so that the transmission ratio CVT is also used for a purely electric drive. Alternatively, the electric machine EM can also be arranged on the transmission output side. However, this results in higher torque requirements for the electric drive. The envisaged separating clutch K0 allows the decoupling of the internal combustion engine VM and the electric machine EM, so that a purely electrical drive is possible.
Im Rahmen des erfindungsgemäßen Verfahrens wird der Antrieb und das Bremsen fahrmodusabhängig bzw. betriebsmodusabhängig entweder durch den Verbrennungsmotor VM oder den Hybridantrieb bzw. die elektrische Maschine EM oder in Kombination durchgeführt, wie dies in
Bei den Betriebsmodi, in denen die Arbeitsmaschine Rückwärtsfahren muss, wird der Antrieb über die elektrische Maschine EM allein durchgeführt und die Drehrichtungsumkehr kann im Hybridsystem durch eine entsprechende Ansteuerung der elektrischen Maschine EM realisiert werden. Dadurch können ein Rückwärtsgang und der Wendekupplungssatz entfallen und eine Umschaltung der Drehrichtung wird im Umkehrpunkt nahe dem Fahrzeugstillstand ermöglicht.In the operating modes in which the work machine must reverse, the drive is performed by the electric machine EM alone and the direction of rotation can be realized in the hybrid system by a corresponding control of the electric machine EM. As a result, a reverse gear and the reversing clutch set can be omitted and a reversal of the direction of rotation is made possible at the reversal point near the vehicle standstill.
Dadurch, dass die Abbremsung der Arbeitsmaschine über die elektrische Maschine EM erfolgt, kann dabei die rekuperierte Energie in dem Energiespeicher
Wenn ausschließlich ein elektrischer Antrieb erfolgt, kann die Trennkupplung K0 geöffnet und der Verbrennungsmotor VM entsprechend abgekoppelt werden. Hierbei ergibt sich der Vorteil, dass der Verbrennungsmotor VM abgeschaltet werden kann, wenn ein Betrieb der Nebenaggregate unabhängig vom Verbrennungsmotor VM aufrechterhalten werden kann, zum Beispiel bei der Verwendung von elektrisch angetriebenen Nebenaggregaten. Wenn die Nebenaggregate über den Verbrennungsmotor VM angetrieben werden, kann durch das Öffnen der Trennkupplung K0 unabhängig vom Betrieb des Verbrennungsmotors VM rein elektrisch vorwärts oder rückwärts gefahren werden.If only an electric drive takes place, the clutch K0 can be opened and the engine VM decoupled accordingly. This results in the advantage that the engine VM can be switched off when an operation of the ancillaries can be maintained independently of the engine VM, for example when using electrically driven ancillaries. If the ancillaries are driven by the engine VM, by opening the clutch K0 regardless of the operation of the engine VM purely electrically forward or backward can be driven.
