Weiters betrifft die Erfindung ein Verfahren zum Betreiben eines Antriebssystems mit einem leistungsverzweigenden Getriebe zwischen einer Eingangs- und einer Ausgangswelle, einem mechanischen Antriebsstrang zur mechanischen Kraftübertragung zwischen der Eingangs- und der Ausgangswelle und einem hydrostatischen Getriebe mit zumindest einem hydraulischen Energiespeicher und mit einer eingangsseitigen und einer ausgangsseitigen hydrostatischen Maschine zur hydraulischen Kraftübertragung zwischen der Eingangswelle und der Ausgangswelle, wobei der mechanische Antriebsstrang und das hydrostatische Getriebe über das leistungsverzweigende Getriebe miteinander verbunden sind, wobei in einem ersten Betriebsmodus die Ausgangswelle mechanisch über den mechanischen Antriebsstrang, und in einem zweiten Betriebsmodus die Ausgangswelle hydraulisch über das hydrostatische Getriebe angetrieben wird und wobei in einem dritten Betriebsmodus zumindest ein Teil der mechanischen Antriebsenergie im hydraulischen Energiespeicher des hydrostatischen Getriebes gespeichert wird.Furthermore, the invention relates to a method for operating a drive system with a power-split transmission between an input and an output shaft, a mechanical drive train for mechanical power transmission between the input and the output shaft and a hydrostatic transmission with at least one hydraulic energy storage and with an input side and a output side hydrostatic machine for hydraulic power transmission between the input shaft and the output shaft, wherein the mechanical drive train and the hydrostatic transmission are interconnected via the power split transmission, wherein in a first operating mode, the output shaft mechanically via the mechanical drive train, and in a second operating mode, the output shaft hydraulically is driven by the hydrostatic transmission and wherein in a third mode of operation, at least a part of the mechanical drive energy in hydra the energy storage of the hydrostatic transmission is stored.

Die
Nutzfahrzeuge und Arbeitsmaschinen weisen üblicherweise eine Arbeitshydraulik zum Betreiben von Arbeitsmaschinen, Geräten, Handhabungseinrichtungen oder dergleichen auf.Commercial vehicles and work machines usually have a working hydraulics for operating machines, equipment, handling equipment or the like.
Aufgabe der Erfindung ist es, ein Antriebssystem zu schaffen, bei dem auch die Arbeitshydraulikeinheit in die Energierückgewinnung von frei werdender Energie miteinbezogen wird.The object of the invention is to provide a drive system in which the working hydraulic unit is included in the energy recovery of energy released.
Erfindungsgemäß wird dies dadurch erreicht, dass eine Arbeitshydraulikeinheit mit dem mechanischen Antriebsstrang, vorzugsweise auf der Seite der Eingangswelle antriebsverbunden ist, wobei die Arbeitshydraulikeinheit zumindest einen hydraulischen Energiespeicher aufweist. Vorzugsweise ist dabei vorgesehen, dass eine hydrostatische Maschine des hydrostatischen Getriebes mit einer hydrostatischen Maschine der Arbeitshydraulik drehverbunden ist.According to the invention, this is achieved in that a working hydraulic unit is drive-connected to the mechanical drive train, preferably on the side of the input shaft, wherein the working hydraulic unit has at least one hydraulic energy store. Preferably, it is provided that a hydrostatic machine of the hydrostatic transmission is rotatably connected to a hydrostatic machine working hydraulics.
Besonders vorteilhaft ist es, wenn das hydrostatische Getriebe hydraulisch von der Arbeitshydraulikeinheit getrennt ist. Dies ermöglicht einen modularen einfachen Aufbau, wobei eine leichte Anpassung an individuelle Bedürfnisse einer Anwendung durchgeführt werden kann. Die separaten hydraulischen Kreise ermöglichen weiters eine einfache Regelung, wobei auch unterschiedliche Druckniveaus für den Arbeitskreis und den Fahrkreis, insbesondere mit unterschiedlichen Druckmedien, verwendet werden können. Insbesondere ist es möglich, unterschiedliche Reinheitsanforderungen an die beiden hydraulischen Kreise zu definieren (üblicherweise sind die Anforderungen im Arbeitshydraulikkreis weniger streng als im Antriebshydraulikkreis).It is particularly advantageous if the hydrostatic transmission is hydraulically separated from the working hydraulic unit. This allows for a modular, simple construction, whereby an easy adaptation to individual needs of an application can be carried out. The separate hydraulic circuits also allow easy control, with different pressure levels for the working and the circle, especially with different media can be used. In particular, it is possible to define different purity requirements for the two hydraulic circuits (usually the requirements in the working hydraulic circuit are less stringent than in the drive hydraulic circuit).
Das leistungsverzweigende Getriebe kann entweder mit einer eingangsseitigen hydraulischen Maschine oder einer ausgangsseitigen hydraulischen Maschine des hydrostatischen Getriebes verbunden sein. The power-split transmission may be connected to either an input-side hydraulic machine or an output-side hydraulic machine of the hydrostatic transmission.
Eine besonders effektive Energierückgewinnung ist möglich, wenn frei werdende potentielle Energie einer mit der Eingangswelle verbundenen Arbeitshydraulikeinheit in zumindest einem hydraulischen Energiespeicher des hydrostatischen Getriebes und/oder der Arbeitshydraulikeinheit gespeichert wird, wobei vorzugsweise Verzögerungsenergie des Fahrzeuges in zumindest einer hydraulischen Energiespeichereinheit des hydrostatischen Getriebes und/oder der Arbeitshydraulikeinheit gespeichert wird.A particularly effective energy recovery is possible when stored potential energy of a connected to the input shaft working hydraulic unit is stored in at least one hydraulic energy storage of the hydrostatic transmission and / or the working hydraulic unit, preferably deceleration energy of the vehicle in at least one hydraulic energy storage unit of the hydrostatic transmission and / or the working hydraulic unit is stored.
Dabei ist es besonders vorteilhaft, wenn Energie aus zumindest einem hydraulischen Energiespeicher des hydrostatischen Getriebes und/oder der Arbeitshydraulikeinheit zum Starten einer Brennkraftmaschine des Antriebssystems und/oder zum Antreiben des Fahrzeuges verwendet wird.It is particularly advantageous if energy from at least one hydraulic energy store of the hydrostatic transmission and / or the working hydraulic unit for starting an internal combustion engine of the drive system and / or for driving the vehicle is used.
