Abstract
Description
Die Erfindung betrifft eine Antriebseinheit für ein Kraftfahrzeug gemäß dem Oberbegriff des Anspruchs 1 und ein Kraftfahrzeug.The invention relates to a drive unit for a motor vehicle according to the preamble of claim 1 and a motor vehicle.
Antriebseinheiten, welche mindestens eine Elektromaschine zum Antrieb eines Kraftfahrzeuges aufweisen, wie beispielsweise Hybridantriebe oder reine Elektroantriebe, benötigen einen Energiespeicher. Dieser Energiespeicher versorgt die Elektromaschine als Motor mit Energie, welche der Elektromotor in eine mechanische Bewegung des Kraftfahrzeuges umsetzt. Gleichzeitig kann aber auch die mechanische Energie, die von dem Kraftfahrzeug aufgebracht wird, mit der Elektromaschine als Generator in eine elektrische Energie umgewandelt werden, die dann wiederum in dem Energiespeicher abgespeichert wird, wodurch der Energiespeicher aufgeladen wird.Drive units which have at least one electric machine for driving a motor vehicle, such as hybrid drives or pure electric drives, require an energy store. This energy storage supplies the electric machine as a motor with energy, which converts the electric motor into a mechanical movement of the motor vehicle. At the same time, however, the mechanical energy that is applied by the motor vehicle can be converted with the electric machine as a generator into an electrical energy, which in turn is then stored in the energy store, whereby the energy storage is charged.
In solchen Antriebseinheiten werden Energiespeicher benötigt, die beispielsweise elektrischen Strom mit einer Spannung von 60 V oder 200 V für die Elektromaschine zur Verfügung stellen müssen und einen großen Raumbedarf auf Grund der hohen Energiespeicherkapazität aufweisen. Dabei ist der Energiespeicher getrennt von der Elektromaschine angeordnet.In such drive units energy storage are needed, for example, must provide electrical power with a voltage of 60 V or 200 V for the electric machine available and have a large space requirement due to the high energy storage capacity. In this case, the energy store is arranged separately from the electric machine.

Eine Antriebseinheit für batteriegespeiste Fahrzeuge ist aus der
Die Aufgabe der vorliegenden Erfindung besteht deshalb darin, eine Antriebseinheit und ein Kraftfahrzeug zur Verfügung zu stellen, bei dem der Energiespeicher und/oder die Elektromaschine möglichst wenig anderweitig nutzbaren Platz benötigten.The object of the present invention is to provide a drive unit and a motor vehicle are available in which the energy storage and / or the electric machine needed as little otherwise usable space.
Diese Aufgabe wird gelöst mit einer Antriebseinheit für ein Kraftfahrzeug, insbesondere für ein Hybridfahrzeug, umfassend wenigstens eine Elektromaschine zur Erzeugung einer Antriebskraft zur Fortbewegung des Kraftfahrzeuges, ein mit der wenigstens einen Elektromaschine verbundenen Energiespeicher zur Versorgung der Elektromaschine mit Energie oder zur Speicherung der von der Elektromaschine abgegebenen Energie, wenigstens eine Antriebswelle und/oder wenigstens eine Achse für ein Rad eines Kraftfahrzeuges, wobei der Energiespeicher und/oder die Elektromaschine wenigstens teilweise einen Bauraum an der wenigstens einen Antriebswelle und/oder der wenigstens einen Achse ausfüllt. Da sich um die wenigstens eine Antriebswelle und/oder die wenigstens eine Achse ungenutzter Bauraum befindet, kann der Energiespeicher und/oder die Elektromaschine an dieser Stelle günstig angeordnet werden. Dadurch ergibt sich eine bessere Raumausnutzung in der Antriebseinheit, wodurch der bisher beanspruchte Platz wieder zur Verfügung steht. Darüber hinaus führt die Anordnung des Energiespeichers an der Antriebswelle und/oder der Achse dazu, dass sich der Schwerpunkt des Kraftfahrzeuges weiter in Richtung Straße verlagert, was für die Straßenlage des Kraftfahrzeuges von Vorteil ist.This object is achieved with a drive unit for a motor vehicle, in particular for a hybrid vehicle, comprising at least one electric machine for generating a driving force for locomotion of the motor vehicle, an energy store connected to the at least one electric machine for supplying the electric machine with energy or for storing the electric machine emitted energy, at least one drive shaft and / or at least one axle for a wheel of a motor vehicle, wherein the energy storage and / or the electric machine at least partially fills a space on the at least one drive shaft and / or the at least one axis. Since there is at least one drive shaft and / or the at least one axis unused space, the energy storage and / or the electric machine can be conveniently located at this point. This results in a better space utilization in the drive unit, whereby the previously claimed space is available again. In addition, the arrangement of the energy storage device on the drive shaft and / or the axle causes the center of gravity of the motor vehicle to shift further in the direction of the road, which is advantageous for the road holding of the motor vehicle.
Vorteilhafterweise umgibt der Energiespeicher und/oder die Elektromaschine in dem Bauraum die wenigstens eine Antriebswelle und/oder wenigstens eine Achse, insbesondere konzentrisch, und/oder der Energiespeicher und/oder die wenigstens eine Elektromaschine ist, insbesondere ausschließlich, in einem Abstand von weniger als 40 cm, 30 cm oder 10 cm zu einer Rotationsachse der wenigstens einen Antriebswelle und/oder der wenigstens einen Achse angeordnet.Advantageously, the energy store and / or the electric machine surrounds the at least one drive shaft and / or at least one axis, in particular concentrically, and / or the energy store and / or the at least one electric machine, in particular exclusively, at a distance of less than 40 cm, 30 cm or 10 cm to an axis of rotation of the at least one drive shaft and / or arranged the at least one axis.
Insbesondere besteht der Energiespeicher aus mehreren Zellen und/oder ist eine Batterie, insbesondere wenigstens eine Lithiumionenbatterie. Neben einer Lithiumbatterie ist nach einer besonderen Ausführungsform jede andere Form eines chemischen Energiespeichers verwendbar.In particular, the energy store consists of several cells and / or is a battery, in particular at least one lithium-ion battery. In addition to a lithium battery, according to a particular embodiment any other form of chemical energy storage can be used.
In einer weiteren Ausgestaltung bildet der Energiespeicher mit der wenigstens einen Antriebswelle und/oder der wenigstens einen Achse eine bauliche Einheit. Auf diese Weise ergibt sich eine kostengünstige und kompakte Antriebseinheit, welche auch leicht nachrüstbar ist.In a further embodiment, the energy store with the at least one drive shaft and / or the at least one axis forms a structural unit. This results in a cost-effective and compact drive unit, which is also easy to retrofit.
In einer ergänzenden Ausführungsform ist die Elektromaschine an der wenigstens einen Antriebswelle angeordnet. Elektromaschine und Energiespeicher bilden somit eine integrierte Einheit, die einfach zu handhaben ist.In an additional embodiment, the electric machine is arranged on the at least one drive shaft. Electric machine and energy storage thus form an integrated unit that is easy to handle.
Vorzugsweise umschließt die Elektromaschine die wenigstens eine Antriebswelle konzentrisch, woraus sich eine gleichmäßige Gewichtsverteilung an der Antriebseinheit ergibt.Preferably, the electric machine surrounds the at least one drive shaft concentrically, resulting in a uniform weight distribution on the drive unit.
In einer Variante ist der Rotor der Elektromaschine auf der wenigstens einen Antriebswelle angeordnet, was eine Einsparung an Bauteilen und somit eine einfachere Konstruktion zur Folge hat, da die Antriebswelle direkt durch die Elektromaschine angetrieben wird.In a variant, the rotor of the electric machine is arranged on the at least one drive shaft, resulting in a saving of components and thus a simpler construction result, since the drive shaft is driven directly by the electric machine.
Zweckmäßig ist die wenigstens eine Elektromaschine Bestandteil der baulichen Einheit aus Energiespeicher und der wenigstens einen Antriebswelle und/oder der wenigstens einen Achse. Dadurch erhöht sich die Kompaktheit der baulichen Einheit und der Einbau von Elektromaschine und Energiespeicher in das Kraftfahrzeug vereinfacht sich wesentlich.Suitably, the at least one electric machine is part of the structural unit of energy storage and the at least one drive shaft and / or the at least one axis. This increases the compactness of the structural unit and the installation of electric machine and energy storage in the motor vehicle simplifies significantly.
Vorteilhafterweise ist die Antriebswelle als Gelenkwelle, vorzugsweise als Kardanwelle, ausgebildet, und/oder die wenigstens eine Elektromaschine und/oder der Energiespeicher sind in einem Kardantunnel des Kraftfahrzeuges angeordnet. Die bauliche Einheit wird dabei durch den an sich im Kraftfahrzeug vorhandenen Kardantunnel begrenzt, dessen Bauraum durch die genannten Bestandteile optimal ausgefüllt wird. Daher wird kein zusätzlicher Platz im Kraftfahrzeug für die erfindungsgemäße Antriebseinheit benötigt.Advantageously, the drive shaft as a propeller shaft, preferably as a propeller shaft, formed, and / or the at least one electric machine and / or the energy storage are arranged in a transmission tunnel of the motor vehicle. The structural unit is limited by the existing in the motor vehicle Kardantunnel, the space is filled optimally by the above components. Therefore, no additional space in the motor vehicle for the drive unit according to the invention is required.
In einer anderen Ausführungsform ist die bauliche Einheit aus der wenigstens einen Antriebswelle und/oder der wenigstens einen Achse, dem Energiespeicher und/oder der wenigstens einen Elektromaschine kühlbar. Auf Grund der Anordnung in dem Kardantunnel kann leicht Luft zum Kühlen zu der baulichen Einheit geleitet werden.In another embodiment, the structural unit of the at least one drive shaft and / or the at least one axis, the energy storage and / or the at least one electric machine is cooled. Due to the arrangement in the transmission tunnel, air can easily be sent to the structural unit for cooling.
In einer ergänzenden Variante koppelt eine erste Antriebswelle ein Zentraldifferentialgetriebe mit einem vorderen Achsdifferentialgetriebe mechanisch und die erste Antriebswelle überträgt das Drehmoment von dem Zentraldifferentialgetriebe auf das vordere Achsdifferentialgetriebe des Kraftfahrzeuges und eine zweite Antriebswelle koppelt das Zentraldifferentialgetriebe mit einem hinteren Achsdifferentialgetriebe mechanisch und die zweite Antriebswelle überträgt das Drehmoment von dem Zentraldifferentialgetriebe auf das hintere Achsdifferentialgetriebe des Kraftfahrzeuges. Die beschriebene Antriebseinheit, bestehend aus Energiespeicher, Elektromaschine und Antriebswelle, lässt sich einfach an die Differentiale ankoppeln, was den Aufwand an Montageleistung verringert.In a supplemental variant, a first drive shaft mechanically couples a center differential with a front differential and the first drive shaft transmits the torque from the center differential to the front axle differential of the motor vehicle and a second drive shaft mechanically couples the center differential with a rear differential and the second drive shaft transmits the torque from the central differential to the rear axle differential of the motor vehicle. The drive unit described, consisting of energy storage, electric machine and drive shaft, can be easily coupled to the differentials, which reduces the cost of assembly capacity.
Vorteilhafterweise bilden das Zentraldifferentialgetriebe und/oder das vordere Achsdifferentialgetriebe und/oder das hintere Achsdifferentialgetriebe die bauliche Einheit mit der wenigstens einen Antriebswelle und/oder der wenigstens einen Achse, der wenigstens einen Elektromaschine und dem Energiespeicher. Dadurch, dass die bauliche Einheit nun auch noch die Achsdifferentialgetriebe und das Zentraldifferentialgetriebe enthält, entsteht ein zentrales Modul, welches einfach an der Vorder- bzw. der Hinterachse des Fahrzeuges montiert werden kann. Ein solches Modul ist auch beim Vorliegen von Halbachsen, wie sie üblicherweise bei allradgetriebenen Kraftfahrzeugen Verwendung finden, problemlos anwendbar.Advantageously, the central differential gearing and / or the front axle differential gearing and / or the rear axle differential gearing form the structural unit with the at least one drive shaft and / or the at least one axle, the at least one electric machine and the energy store. The fact that the structural unit now also contains the axle differential and the central differential gear, creates a central module, which can be easily mounted on the front or the rear axle of the vehicle. Such a module is also in the presence of semi-axes, as they are commonly used in four-wheel drive vehicles, easily applicable.
In einer weiteren Ausgestaltung verbindet eine dritte Antriebswelle das Zentraldifferentialgetriebe mit einer Motorwelle eines Verbrennungsmotors. Somit lässt sich das Antriebmodul auch einfach an einen Verbrennungsmotor anschließen, wodurch ein konstruktiv einfacher Hybridantrieb entsteht.In a further embodiment, a third drive shaft connects the central differential with a motor shaft of an internal combustion engine. Thus, the drive module can also be easily connected to an internal combustion engine, creating a structurally simple hybrid drive.
Vorzugsweise ist die Vorderachse des Kraftfahrzeuges getrennt von der Hinterachse des Kraftfahrzeuges antreibbar, wobei die Vorderachse von dem Verbrennungsmotor und die Hinterachse von der in der baulichen Einheit angeordneten Elektromaschine als Motor antreibbar ist.Preferably, the front axle of the motor vehicle is driven separately from the rear axle of the motor vehicle, wherein the front axle of the internal combustion engine and the rear axle of the electric machine arranged in the structural unit can be driven as a motor.
Vorzugsweise verbindet die Antriebswelle eine Motorwelle eines Verbrennungsmotors, welcher sich im Bereich der Vorderachse des Kraftfahrzeuges befindet, mit einem Getriebe, welches sich im Bereich der Hinterachse des Kraftfahrzeuges befindet, und die Antriebswelle überträgt das Drehmoment von der Motorwelle des Verbrennungsmotors auf das Getriebe am anderen Ende des Kraftfahrzeuges. Das Kraftfahrzeug ist daher mit einem sogenannten „Transaxle” Antriebsstrang ausgestattet. Der Bereich um eine Transaxle-Antriebswelle eignet sich aufgrund des Fahrzeugaufbaus besonders gut zur Anordnung eines Energiespeichers und/oder einer Elektromaschine.Preferably, the drive shaft connects a motor shaft of an internal combustion engine, which is located in the region of the front axle of the motor vehicle, with a transmission, which is located in the region of the rear axle of the motor vehicle, and the drive shaft transmits the torque from the engine shaft of the internal combustion engine to the transmission at the other end of the motor vehicle. The motor vehicle is therefore equipped with a so-called "transaxle" drive train. The area around a transaxle drive shaft is particularly well suited to the arrangement of an energy storage and / or an electric machine due to the vehicle body.
In einer Ausgestaltung der Erfindung ist die Antriebseinheit als Gelenkwelle, vorzugsweise als Kardanwelle ausgebildet, und/oder die wenigstens eine Elektromaschine und/oder der Energiespeicher sind in einem sog. „Torquetube” des Kraftfahrzeuges angeordnet. Torquetubes werden insbesondere im Zusammenhang mit Transaxle-Fahrzeugen eingesetzt. Ein Torquetube stellt ein Hohlprofil rund um eine Antriebswelle dar und muss, etwa im Gegensatz zu einem üblichen Kardantunnel, erhöhte Anforderungen an dessen Steifigkeit erfüllen. Daher weist ein Torquetube meist einen entsprechend großen Durchmesser auf. Durch den im Vergleich dazu kleinen Durchmesser der Antriebswelle entsteht zwischen Antriebswelle und Torquetube ein relativ großer, sonst ungenutzter Hohlraum. Dieser ohnehin vorhandene Bauraum wird durch die genannten Bauteile optimal genutzt. Daher wird kein zusätzlicher Platz im Kraftfahrzeug für die erfindungsgemäße Antriebseinheit benötigt. Ein weiterer Vorteil dieser Anordnung ergibt sich oft dadurch, dass Torquetubes üblicherweise gut abgedichtet ausgeführt werden. Die innerhalb eines Torquetube verbauten Bauteile, wie Energiespeicher und/oder zumindest eine Elektromaschine sind daher gut geschützt vor Umwelteinflüssen.In one embodiment of the invention, the drive unit is designed as a propeller shaft, preferably as a cardan shaft, and / or the at least one electric machine and / or the energy store are arranged in a so-called "Torquetube" of the motor vehicle. Torquetubes are used in particular in connection with transaxle vehicles. A Torquetube represents a hollow profile around a drive shaft and must, in contrast to a conventional transmission tunnel, meet increased rigidity requirements. Therefore, a Torquetube usually has a correspondingly large diameter. Due to the small diameter compared to the drive shaft between the drive shaft and Torquetube a relatively large, otherwise unused cavity. This already existing space is optimally used by the mentioned components. Therefore, no additional space in the motor vehicle for the drive unit according to the invention is required. Another advantage of this Arrangement often results from Torquetubes are usually performed well sealed. The installed within a Torquetube components, such as energy storage and / or at least one electric machine are therefore well protected against environmental influences.
