Abstract
Das Leistungsverzweigungsgetriebe weist eine Eingangswelle 3 auf, welche über das Zahnrad 4 die Vorgelegewelle 7 antreibt, welche einerseits mit dem Variator 11 und andererseits mit der Nebenabtriebswelle 14 in Wirkverbindung steht. Dadurch ist es möglich, den Variator 11 und die Nebenabtriebswelle 14 mit wenigen Stirnräder und Wellen mit der Eingangswelle 3 zu koppeln.The power split transmission has an input shaft 3, which drives the countershaft 7 via the gearwheel 4, which is operatively connected to the variator 11 and to the power take-off shaft 14. This makes it possible to couple the variator 11 and the power take-off shaft 14 to the input shaft 3 with a few spur gears and shafts.
Description
Die Erfindung betrifft ein Leistungsverzweigungsgetriebe nach der im Oberbegriff von Anspruch 1 näher definierten Art.The invention relates to a power split transmission according to the kind defined in the preamble of
Gattungsgemäße Leistungsverzweigungsgetriebe werden insbesondere für landwirtschaftliche oder kommunale Nutzfahrzeuge verwendet. Ein derartiges landwirtschaftliches Nutzfahrzeug ist beispielsweise ein Traktor.Generic power split transmissions are used in particular for agricultural or municipal utility vehicles. Such an agricultural utility vehicle is, for example, a tractor.
Die
Der Begriff Variator bezeichnet eine Variatormaschine in einem Leistungsverzweigungsgetriebe.The term variator denotes a variator machine in a power split transmission.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein leistungsverzweigtes Getriebe zu schaffen, mittels welchem die Arbeitshydraulikpumpen und die Variatoren auf einfache Weise antreibbar sind und das Getriebe bezüglich der Variatoren modular aufgebaut sein kann.
Die Aufgabe wird mit einem auch die kennzeichnenden Merkmale des Hauptanspruchs aufweisenden gattungsgemäßen Leistungsverzweigungsgetriebe gelöst.The present invention has for its object to provide a power-split transmission, by means of which the working hydraulic pumps and the variators can be driven in a simple manner and the transmission can be constructed modularly with respect to the variators.
The object is achieved with a generic power split transmission which also has the characterizing features of the main claim.
Erfindungsgemäß weist das Leistungsverzweigungsgetriebe eine Eingangswelle auf, welche mit einem Antriebsmotor, beispielsweise einem Verbrennungsmotor, verbindbar ist und welche durch das gesamte Leistungsverzweigungsgetriebe hindurchgeführt ist. Koaxial zu dieser Eingangswelle sind mehrere Planetenstufen angeordnet, welche mit Kupplungen so angesteuert werden können, dass mehrere Fahrbereiche schaltbar sind. Auch die Kupplungen sind koaxial zur Eingangswelle angeordnet. Des Weiteren weist das Leistungsverzweigungsgetriebe eine Kupplung für Vorwärtsfahrt und eine Kupplung für Rückwärtsfahrt auf, welche den Planetenstufen nachgeordnet angeordnet ist. Auf der, dem Antriebsmotor entgegengesetzten Ende der Eingangswelle, ist ein Zahnrad mit der Antriebswelle verbunden. Über dieses Zahnrad wird ein Variator und ein Nebenabtrieb, beispielsweise für die Arbeitshydraulik und/oder die Lenkpumpen, angetrieben.According to the invention, the power split transmission has an input shaft which can be connected to a drive motor, for example an internal combustion engine, and which is guided through the entire power split transmission. Several planetary stages are arranged coaxially with this input shaft, which can be controlled with clutches in such a way that several driving ranges can be switched. The couplings are also arranged coaxially to the input shaft. Furthermore, the power split transmission has a clutch for forward travel and a clutch for reverse travel, which is arranged downstream of the planetary stages. A gear wheel is connected to the drive shaft on the end of the input shaft opposite the drive motor. A variator and a power take-off, for example for the working hydraulics and / or the steering pumps, are driven via this gear wheel.
In einer Ausgestaltungsform der Erfindung ist das Zahnrad, welches mit der Eingangswelle verbunden ist, in Wirkverbindung mit einem Stirnrad einer Vorgelegewelle, deren weiteres Stirnrad mit dem Stirnrad der Antriebswelle des Variators kämmt. Zusätzlich kämmt dieses Stirnrad über ein Zwischenrad mit einem Stirnrad, welches die Welle des Nebenabtriebs antreibt. Dadurch ist es möglich, die Variatoren entweder seitlich außerhalb der Planetenstufen oder zwischen dem Antriebsmotor und den Planetenstufen anzuordnen. Vorzugsweise sind die Variatoren als elektrische Maschinen ausgebildet, welche durch diese Erfindung in einem separaten Getriebegehäuse gelagert sein können. Sind die Variatoren außerhalb der Planetenstufen angeordnet, so sind die Variatoren parallel zur Eingangswelle angeordnet.
Sind die Variatoren nicht neben den Planetenstufen angeordnet, sondern koaxial zu der Eingangswelle, so kann der Raum neben den Planetenstufen genutzt werden um die Leistungselektronik für die Variatoren, welche als elektrische Maschinen ausgebildet sind, anzuordnen. Die Leistungselektronik kann hierbei innerhalb des Getriebegehäuses oder außerhalb des Getriebegehäuses angeordnet und am Getriebegehäuse befestigt sein.In one embodiment of the invention, the gearwheel, which is connected to the input shaft, is operatively connected to a spur gear of a countershaft, the further spur gear of which meshes with the spur gear of the drive shaft of the variator. In addition, this spur gear meshes via an idler gear with a spur gear that drives the power take-off shaft. This makes it possible to arrange the variators either laterally outside the planetary stages or between the drive motor and the planetary stages. The variators are preferably designed as electrical machines, which can be stored in a separate gear housing by this invention. If the variators are arranged outside the planetary stages, the variators are arranged parallel to the input shaft.
If the variators are not arranged next to the planetary stages, but coaxial to the input shaft, the space next to the planetary stages can be used to arrange the power electronics for the variators, which are designed as electrical machines. The power electronics can be arranged inside the transmission housing or outside the transmission housing and can be attached to the transmission housing.
In einer weiteren Ausgestaltungsform der Erfindung sind die beiden Variatoren als elektrische Maschinen nahezu gleicher Größe ausgebildet, wodurch der Variator, welcher mit der Planetenstufe in Wirkverbindung steht, eine niedrigere Drehzahl aufweisen kann. Dadurch besteht die Möglichkeit, eine verhältnismäßig lange Welle, welche über die gesamte Getriebebaulänge reichen kann, zum Antrieb des Variators, welcher über das Stirnradgetriebe mit der Eingangswelle angetrieben wird, zu verwenden.In a further embodiment of the invention, the two variators are designed as electrical machines of almost the same size, as a result of which the variator, which is operatively connected to the planetary stage, can have a lower speed. This makes it possible to use a relatively long shaft, which can extend over the entire length of the transmission, to drive the variator, which is driven by the spur gear with the input shaft.
