Description
Die Erfindung betrifft einen Antriebsstrang nach der im Oberbegriff von Anspruch 1 näher definierten Art.The invention relates to a drive train according to the closer defined in the preamble of
Gattungsgemäße Antriebsstränge werden hauptsächlich in Arbeitsmaschinen wie beispielsweise Traktoren verwendet. Hierbei treibt ein Antriebsmotor über ein schaltbares Getriebe beispielsweise ein hydrostatisch-mechanisch leistungsverzweigtes Getriebe eine Hinterachse, wahlweise eine Vorderachse und zusätzlich einen Nebenabtrieb an.Generic drive trains are mainly used in working machines such as tractors. Here drives a drive motor via a shiftable transmission, for example, a hydrostatic-mechanical power-split transmission a rear axle, optionally a front axle and additionally a power take-off.
Die
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen Antriebsstrang insbesondere für einen Traktor zu schaffen, welcher den Antriebsstrang nach dem Stand der Technik weiter verbessert.The present invention has for its object to provide a drive train, in particular for a tractor, which further improves the drive train according to the prior art.
Die Aufgabe wird mit einem auf die kennzeichnenden Merkmale des Hauptanspruchs aufweisenden gattungsgemäßen Antriebsstrang gelöst.The problem is solved with a generic drive train having the characterizing features of the main claim.
Erfindungsgemäß weist der Antriebsstrang einen Eingang auf, welcher mit einem Verbrennungsmotor verbunden ist. Der Eingang ist mit einer Eingangswelle des Getriebes und mit einer elektrischen Maschine verbunden. Somit besteht die Möglichkeit, dass der Verbrennungsmotor sowohl die elektrische Maschine antreibt als auch die Eingangswelle des Getriebes. Die elektrische Maschine kann somit als Generator verwendet werden, es besteht jedoch auch die Möglichkeit, bei Verwenden eines elektrischen Speichers, beispielsweise eines Akkumulators, die elektrische Maschine zusätzlich als elektrischen Motor zu verwenden. Das Getriebe kann ein hydrostatisch-mechanisch leistungsverzweigtes Getriebe mit mehreren Fahrbereichen sein. Es besteht jedoch auch die Möglichkeit, das Getriebe als konventionelles Schaltgetriebe auszubilden. Die Eingangswelle des Getriebes ist direkt mit einer Ausgangswelle verbunden, welche mit einem Nebenabtrieb verbunden werden kann. Vorzugsweise ist eine Kupplung vor dem Ausgang für den Nebenabtrieb angeordnet, um den Nebenabtrieb zu- oder abschalten zu können. Der Begriff Kupplung im Öffnungssinne betätigt bedeutet hierbei, dass der Kraftfluss zwischen dem Eingang der Kupplung und dem Ausgang der Kupplung unterbrochen ist. Die Kupplung im Schließsinne betätigt bedeutet hierbei, dass der Kraftfluss zwischen der Eingangswelle der Kupplung und der Ausgangswelle der Kupplung nicht unterbrochen ist und somit die Kupplung Drehmoment übertragen kann. Das Getriebe weist eine weitere Ausgangswelle auf, welche mit einer Hinterachse des Fahrzeugs in Verbindung steht. Über eine weitere Kupplung kann die Vorderachse des Fahrzeugs beziehungsweise die weitere Ausgangswelle des Antriebsstrangs bei im Schließsinne betätigter Kupplung mit der Abtriebswelle des Getriebes verbunden werden. Dadurch ist es möglich, die Hinterachse und die Vorderachse über das Getriebe anzutreiben. Wird jedoch diese Kupplung im Öffnungssinne betätigt und eine Kupplung im Schließsinne betätigt, mit welcher eine weitere elektrische Maschine mit dieser Abtriebswelle zum Antrieb der Vorderachse verbunden wird, so kann die Vorderachse unabhängig von der Abtriebsdrehzahl der Abtriebswelle des Getriebes von der weiteren elektrischen Maschine angetrieben werden. Dadurch ist es möglich, je nach angesteuerter Drehzahl der Vorderachse im Verhältnis zur Drehzahl der Hinterachse entweder besonders bodenschonend das Fahrzeug zu betreiben oder einen besonders kleinen Wendekreis zu erreichen. Bei Verwendung eines Akkumulators oder anderen elektrischen Verbrauchern kann sowohl die elektrische Maschine, welche auf der Eingangswelle des Getriebes angeordnet ist, als auch die weitere elektrische Maschine, welche mit der Vorderachse verbindbar ist, als Generator verwendet werden, um zusätzlich zu den Betriebsbremsen verzögernd auf das Fahrzeug zu wirken. Dadurch kann entweder die Betriebsbremse geschont werden oder die Betriebsbremse in ihrer Dimensionierung kleiner ausfallen.According to the invention, the drive train has an input which is connected to an internal combustion engine. The input is connected to an input shaft of the transmission and to an electric machine. Thus, there is a possibility that the engine drives both the electric machine and the input shaft of the transmission. The electric machine can thus be used as a generator, but there is also the possibility, when using an electrical storage, such as a rechargeable battery, to use the electric machine in addition as an electric motor. The transmission can be a hydrostatic-mechanical power split transmission with several driving ranges. However, it is also possible to design the transmission as a conventional transmission. The input shaft of the transmission is directly connected to an output shaft, which can be connected to a power take-off. Preferably, a clutch is arranged in front of the output for the power take-off in order to enable or disable the power take-off can. The term clutch actuated in the opening direction here means that the power flow between the input of the clutch and the output of the clutch is interrupted. The clutch operated in the closing direction here means that the power flow between the input shaft of the clutch and the output shaft of the clutch is not interrupted and thus the clutch can transmit torque. The transmission has a further output shaft which communicates with a rear axle of the vehicle. Via a further clutch, the front axle of the vehicle or the further output shaft of the drive train can be connected to the output shaft of the transmission when the clutch is operated in the closing direction. This makes it possible to drive the rear axle and the front axle via the transmission. However, if this clutch is actuated in the opening direction and a clutch is actuated in the closing direction, with which a further electric machine is connected to this output shaft for driving the front axle, the front axle can be driven by the further electric machine independently of the output speed of the output shaft of the transmission. This makes it possible, depending on the driven speed of the front axle in relation to the rotational speed of the rear axle to operate either particularly gentle on the soil the vehicle or to achieve a particularly small turning circle. When using a rechargeable battery or other electrical consumers, both the electric machine, which is arranged on the input shaft of the transmission, and the further electric machine, which is connectable to the front axle, can be used as a generator to delay in addition to the service brakes on the Vehicle to act. As a result, either the service brake can be spared or the service brake can be smaller in size.
Indem die Vorderachse vollständig vom Kraftfluss des Getriebes getrennt werden kann, besteht die Möglichkeit, ausschließlich über die weitere elektrische Maschine die Vorderachse anzutreiben, wodurch das Fahrzeug auch bei stillstehendem Verbrennungsmotor bewegt werden kann. Weist das Getriebe eine Kupplung auf, mit welcher die Drehmomentübertragung zur Abtriebswelle des Getriebes unterbrochen werden kann, so besteht die Möglichkeit, mit der weiteren elektrischen Maschine bei geschlossenen Kupplungen zwischen der elektrischen Maschine und der Vorderachse und der elektrischen Maschine und der Hinterachse sowohl die Vorderachse als auch die Hinterachse über die weitere elektrische Maschine anzutreiben, auch wenn der Verbrennungsmotor stillsteht. Die Energie hierfür wird aus einem Akkumulator entnommen, welcher zuvor über den Betrieb der elektrischen Maschinen oder einer elektrischen Maschine angetrieben vom Verbrennungsmotor eingespeist wurde. Bei Verwendung eines Akkumulators besteht auch die Möglichkeit, sowohl die elektrische Maschine auf der Eingangswelle als auch die weitere elektrische Maschine als Motor zu verwenden, wodurch zusätzlich zur Leistung, welche der Verbrennungsmotor abgibt, die Leistung, welche die beiden elektrischen Motoren abgeben, hinzuaddiert werden kann.By the front axle can be completely separated from the power flow of the transmission, it is possible to drive exclusively on the other electric machine, the front axle, whereby the vehicle can be moved even when the engine is stationary. If the transmission has a clutch with which the torque transmission to the output shaft of the transmission can be interrupted, it is possible with the further electric machine with closed clutches between the electric machine and the front axle and the electric machine and the rear axle both the front axle also to drive the rear axle on the other electric machine, even when the internal combustion engine is stationary. The energy for this is taken from an accumulator, which was previously fed via the operation of the electric machines or an electric machine driven by the internal combustion engine. When using an accumulator, it is also possible to use both the electric machine on the input shaft and the other electric machine as a motor, which in addition to the power that emits the engine, the power that the two electric motors deliver, can be added ,
Da die weitere elektrische Maschine sowohl ausschließlich mit der Vorderachse verbindbar ist als auch mit der Vorderachse und der Hinterachse verbindbar ist und hierbei die Verbindung zum Verbrennungsmotor zu unterbrechen, indem eine Kupplung im Getriebe geöffnet wird, besteht die Möglichkeit, die weitere elektrische Maschine in der entgegengesetzten Drehrichtung zu betreiben, wodurch das Fahrzeug in die entgegengesetzte Fahrtrichtung bewegbar ist. Somit kann ein Rückwärtsgang im Getriebe entfallen. Die Energie für die weitere elektrische Maschine kann hierbei entweder von der elektrischen Maschine angetrieben durch den Verbrennungsmotor stammen, es besteht jedoch auch die Möglichkeit, diese Energie aus einem Akkumulator zu entnehmen. Da die Drehrichtung der weiteren elektrischen Maschine sowohl in Vorwärtsfahrtrichtung als auch in Rückwärtsfahrtrichtung möglich ist, kann im Getriebe die Übersetzungen und die Kupplung für Rückwärtsfahrt vollständig entfallen. Das Getriebe kann somit ohne die Rückwärtsfahrtkupplung einfacher und kostengünstiger ausgebildet werden.Since the further electric machine is connectable exclusively to the front axle can also be connected to the front axle and the rear axle and thereby interrupt the connection to the engine by a clutch is opened in the transmission, it is possible to operate the other electric machine in the opposite direction, whereby the vehicle is movable in the opposite direction , Thus, a reverse gear omitted in the transmission. The energy for the further electric machine can in this case either come from the electric machine driven by the internal combustion engine, but it is also possible to remove this energy from an accumulator. Since the direction of rotation of the other electric machine in both the forward direction and in the reverse direction is possible in the transmission, the ratios and the clutch for reversing completely eliminated. The transmission can thus be made simpler and less expensive without the reverse clutch.
Da die Vorderachse ausschließlich ohne Beeinflussung der Drehzahl der Hinterachse von der weiteren elektrischen Maschine antreibbar ist, kann die Vorderachse durch entsprechende Regeleinrichtungen im Vorwärtsfahrtbetrieb schlupffrei betrieben werden. Es besteht jedoch auch die Möglichkeit, die Vorderachse so anzusteuern, dass diese besonders bodenschonend oder für einen geringen Wendekreis angesteuert wird. Vorzugsweise wird die Vorderachse bis zu einer bestimmten Fahrgeschwindigkeit, beispielsweise 18 km/h, ausschließlich von der weiteren elektrischen Maschine angetrieben, da diese Fahrbereiche vorzugsweise abseits der Straße im Feld verwendet werden.Since the front axle can only be driven by the further electric machine without influencing the rotational speed of the rear axle, the front axle can be operated without slip by corresponding control devices in forward drive operation. However, there is also the possibility to control the front axle so that it is particularly gentle on the ground or driven for a small turning circle. Preferably, the front axle is driven up to a certain driving speed, for example 18 km / h, exclusively by the further electric machine, since these driving ranges are preferably used off the road in the field.
Die elektrische Maschine, welche direkt vom Verbrennungsmotor angetrieben ist, kann auch dazu verwendet werden, weitere elektrische Verbraucher, wie beispielsweise einen elektrisch betriebenen Anhänger, mit Energie zu versorgen. Es besteht auch die Möglichkeit, die elektrische Maschine und die weitere elektrische Maschine zur Energieversorgung von weiteren elektrischen Verbrauchern außerhalb des Fahrzeugs zu verwenden, wobei die weitere elektrische Maschine in diesem Zustand dann von der Vorderachse angetrieben wird.The electric machine, which is driven directly by the internal combustion engine, can also be used to power other electrical consumers, such as an electrically powered trailer. It is also possible to use the electric machine and the further electric machine for supplying power to other electrical consumers outside the vehicle, wherein the further electric machine is then driven by the front axle in this state.
