Description
Die Erfindung betrifft eine Getriebeeinheit (auch als (dediziertes) Hybridgetriebe bezeichnet) für ein hybrides Kraftfahrzeug, mit einem Planetengetriebe, wobei das Planetengetriebe mit einem ersten Planetenradsatz und einem zweiten Planetenradsatz ausgestattet ist, zwei elektrischen Maschinen, wobei eine erste elektrische Maschine mit einem ersten Sonnenrad, das sich mit dem ersten Planetenradsatz in Zahneingriff befindet, gekoppelt ist, sowie mehreren, jeweils eine Bremse oder eine Kupplung bildenden und zwischen einer aktivierten Stellung und einer deaktivierten Stellungen verstellbaren Schalteinrichtungen, wobei die Schalteinrichtungen zum Schalten verschiedener Getriebeübersetzungen zwischen einem mit einem Verbrennungsmotor koppelbaren Eingang sowie einem Ausgang und/oder zwischen der ersten elektrischen Maschine sowie dem Ausgang wirkend eingesetzt sind. Des Weiteren betrifft die Erfindung einen Antriebsstrang und ein Kraftfahrzeug.The invention relates to a transmission unit (also referred to as a (dedicated) hybrid transmission) for a hybrid motor vehicle, with a planetary gear, the planetary gear being equipped with a first planetary gear set and a second planetary gear set, two electric machines, a first electric machine with a first sun gear , which is in meshing engagement with the first planetary gear set, and a plurality of switching devices, each forming a brake or a clutch and adjustable between an activated position and a deactivated position, the switching devices for switching different gear ratios between an input that can be coupled to an internal combustion engine as well as an output and / or between the first electrical machine and the output. The invention further relates to a drive train and a motor vehicle.
Aus dem Stand der Technik sind bereits verschiedene gattungsgemäße Ausführungen von Hybridgetrieben realisiert. Beispielsweise ist mit der
Weiterer Stand der Technik ist mit der
Als Nachteil der aus dem Stand der Technik bekannten Ausführungen hat es sich jedoch herausgestellt, dass die bekannten Getriebeeinheiten häufig einen relativ komplexen Aufbau aufweisen, was an der relativ hohen Anzahl an vorhandener Schalteinrichtungen liegt. Dies bringt einen erhöhten Herstell- und Montageaufwand sowie einen erhöhten Bauraumbedarf mit sich. Gewisse Anordnungen der Getriebeeinheit relativ zu einem Verbrennungsmotor des jeweiligen Kraftfahrzeuges lassen sich daher nicht oder nur relativ schwierig umsetzen.A disadvantage of the designs known from the prior art has been found, however, that the known gear units often have a relatively complex structure, which is due to the relatively high number of switching devices available. This entails increased manufacturing and assembly costs and an increased space requirement. Certain arrangements of the gear unit relative to an internal combustion engine of the respective motor vehicle can therefore not be implemented or can only be implemented with relatively difficulty.
Es ist daher die Aufgabe der vorliegenden Erfindung, die aus dem Stand der Technik bekannten Nachteile zu beheben und insbesondere eine hybride Getriebeeinheit zur Verfügung zu stellen, die einen möglichst einfachen Aufbau und eine vielseitige Einsetzbarkeit aufweist und kompakt umgesetzt ist.It is therefore the object of the present invention to remedy the disadvantages known from the prior art and, in particular, to provide a hybrid transmission unit which is as simple as possible in construction and versatile in use and is implemented in a compact manner.
Dies wird erfindungsgemäß dadurch gelöst, dass die erste elektrische Maschine derart angeordnet ist, dass in der aktivierten Stellung zumindest einer Schalteinrichtung die zumindest eine Schalteinrichtung zum rotatorischen Koppeln des Eingangs mit einem den ersten Planetenradsatz aufnehmenden ersten Planetenträger dient, sodass bei einem Ansteuern der ersten elektrischen Maschine als Generator ein Betriebszustand zur Erzeugung einer variabel einstellbaren Getriebeübersetzung (eCVT-Betrieb) umsetzbar ist.This is achieved according to the invention in that the first electrical machine is arranged in such a way that, in the activated position of at least one switching device, the at least one switching device is used for rotational coupling of the input to a first planet carrier receiving the first planetary gear set, so that when the first electrical machine is activated an operating state for generating a variably adjustable transmission ratio (eCVT operation) can be implemented as a generator.
Die Anzahl an vorhandenen Schalteinrichtungen wird weitgehend reduziert, wobei zugleich durch die beiden elektrischen Maschinen ein leistungsfähiger Antrieb zur Verfügung gestellt wird. Auch findet durch verschiedene Getriebeübersetzungen in einem Antriebszustand des Verbrennungsmotors sowie der elektrischen Maschinen eine ausreichende Leistungswandlung statt.The number of existing switching devices is largely reduced, while at the same time a powerful drive is made available by the two electrical machines. Adequate power conversion also takes place through different gear ratios in a drive state of the internal combustion engine and of the electrical machines.
Weitere vorteilhafte Ausführungen sind mit den Unteransprüchen beansprucht und nachfolgend näher erläutert.Further advantageous designs are claimed with the subclaims and explained in more detail below.
Demnach ist es von Vorteil, wenn die weitere, zweite elektrische Maschine direkt oder indirekt mit dem Ausgang oder mit einer Hinterachse des Kraftfahrzeuges verbunden ist. Dadurch ergibt sich eine hinsichtlich des Wirkungsgrades optimierte Anordnung der üblicherweise als Antriebsmotor eingesetzten zweiten elektrischen Maschine. Besonders vorteilhaft ist die zweite elektrische Maschine direkt / unmittelbar mit dem Ausgang verbunden. In weiter bevorzugten Ausführungen ist die zweite elektrische Maschine indirekt mit dem Ausgang verbunden, etwa durch eine Verzahnung oder durch ein Endloszugmittel, wie eine Kette. Die zweite elektrische Maschine kann sich auch direkt mit einer Differenzialkrone eines Differenzialgetriebes in Eingriff befinden. It is therefore advantageous if the further, second electrical machine is connected directly or indirectly to the output or to a rear axle of the motor vehicle. This results in an arrangement of the second electrical machine, which is usually used as a drive motor, which is optimized in terms of efficiency. The second electrical machine is particularly advantageously connected directly / directly to the output. In further preferred embodiments, the second electrical machine is indirectly connected to the output, for example by a toothing or by an endless traction means, such as a chain. The second electrical machine can also be directly engaged with a differential crown of a differential gear.
Zudem ist es zweckmäßig, wenn eine erste Schalteinrichtung und / oder eine zweite Schalteinrichtung (der vorzugsweise nicht mehr als vier Schalteinrichtungen) als Kupplung ausgebildet sind / ist. Dadurch lässt sich der Verbrennungsmotor geschickt von dem Planetengetriebe entkoppeln.In addition, it is expedient if a first switching device and / or a second switching device (which preferably does not have more than four switching devices) are / are designed as a clutch. This allows the combustion engine to be decoupled from the planetary gear.
Als zweckmäßig hat es sich dabei herausgestellt, wenn die erste Schalteinrichtung als eine Kupplung, die zwischen dem Eingang und dem ersten Sonnenrad wirkend eingesetzt ist, ausgebildet ist, sodass in der aktivierten Stellung der ersten Schalteinrichtung der Eingang mit dem ersten Sonnenrad rotatorisch verbunden ist (d.h. eine Antriebsleistung zwischen dem Eingang und dem ersten Sonnenrad übertragbar ist) und in der deaktivierten Stellung der ersten Schalteinrichtung der Eingang von dem ersten Sonnenrad entkoppelt ist (d.h. keine Antriebsleistung zwischen dem Eingang und dem ersten Sonnenrad übertragbar ist).It has proven to be expedient if the first switching device acts as a clutch, which acts between the input and the first sun gear is inserted, is designed so that in the activated position of the first switching device the input is connected to the first sun gear in a rotational manner (ie a drive power can be transmitted between the input and the first sun wheel) and in the deactivated position of the first switching device the input from the first Sun gear is decoupled (ie no drive power can be transmitted between the input and the first sun gear).
Seitens der zweiten Schalteinrichtung ist es besonders zweckmäßig, wenn diese als eine Kupplung, die zwischen dem Eingang und dem ersten Planetenträger des ersten Planetenradsatzes wirkend eingesetzt ist, ausgebildet ist, sodass in der aktivierten Stellung der zweiten Schalteinrichtung der Eingang mit dem ersten Planetenträger rotatorisch verbunden ist (d.h. eine Antriebsleistung zwischen dem Eingang und dem ersten Planetenträger übertragbar ist) und in der deaktivierten Stellung der zweiten Schalteinrichtung der Eingang von dem ersten Planetenträger entkoppelt ist (d.h. keine Antriebsleistung zwischen dem Eingang und dem ersten Planetenträger übertragbar ist).On the part of the second switching device, it is particularly expedient if it is designed as a clutch which is inserted between the input and the first planet carrier of the first planetary gear set, so that the input is rotationally connected to the first planet carrier in the activated position of the second switching device (ie drive power can be transmitted between the input and the first planet carrier) and in the deactivated position of the second switching device the input is decoupled from the first planet carrier (ie no drive power can be transmitted between the input and the first planet carrier).
Des Weiteren ist es zweckmäßig, wenn eine dritte Schalteinrichtung und / oder eine vierte Schalteinrichtung (der nicht mehr als vier Schalteinrichtungen) als Bremse ausgebildet sind / ist. Dadurch lassen sich auch die übrigen Getriebeübersetzungen einfach schalten.Furthermore, it is expedient if a third switching device and / or a fourth switching device (of no more than four switching devices) are / are designed as a brake. This means that the other gear ratios can also be easily switched.
Von Vorteil ist es in dem Zusammenhang zudem, wenn die dritte Schalteinrichtung als eine auf ein zweites Sonnenrad einwirkende Bremse ausgebildet ist, wobei das zweite Sonnenrad mit einem zweiten Planetenradsatz des Planetengetriebes in Zahneingriff steht, sodass in der aktivierten Stellung der dritten Schalteinrichtung eine Rotation des zweiten Sonnenrades blockiert ist und in der deaktivierten Stellung der dritten Schalteinrichtung eine freie Rotation des zweiten Sonnenrades ermöglicht ist.In this context, it is also advantageous if the third switching device is designed as a brake acting on a second sun gear, the second sun gear being in tooth engagement with a second planetary gear set of the planetary gear, so that in the activated position of the third switching device, rotation of the second one Sun gear is blocked and in the deactivated position of the third switching device a free rotation of the second sun gear is made possible.
Für die vierte Schalteinrichtung ist es des Weiteren zweckmäßig, wenn diese als eine auf das erste Sonnenrad einwirkende Bremse ausgebildet ist, sodass in der aktivierten Stellung der vierten Schalteinrichtung eine Rotation des ersten Sonnenrades blockiert ist und in der deaktivierten Stellung der vierten Schalteinrichtung eine freie Rotation des ersten Sonnenrades ermöglicht ist.For the fourth switching device, it is also expedient if it is designed as a brake acting on the first sun gear, so that rotation of the first sun gear is blocked in the activated position of the fourth switching device and free rotation of the fourth switching device in the deactivated position first sun gear is enabled.
Besonders bevorzugt sind die vier Schalteinrichtungen zum Umsetzen von vier unterschiedlichen Getriebeübersetzungen in einem Antriebszustand des Verbrennungsmotors ausgebildet. In diesem Zusammenhang ist es insbesondere vorteilhaft, wenn zudem ein Standladezustand über diese vier Schalteinrichtungen gebildet wird, indem der Verbrennungsmotor der ersten elektrischen Maschine, die als Generator wirkt, eine Antriebsleistung zuführt. Weiterhin ist es vorteilhaft, wenn die vier Schalteinrichtungen ein Rückwärtsfahren in einem elektrischen Betrieb der ersten elektrischen Maschine oder der zweiten elektrischen Maschine ermöglichen.The four shifting devices are particularly preferably designed to convert four different gear ratios in a drive state of the internal combustion engine. In this context, it is particularly advantageous if, in addition, a state of charge is formed via these four switching devices, in that the internal combustion engine supplies drive power to the first electrical machine, which acts as a generator. Furthermore, it is advantageous if the four switching devices enable reverse travel in electrical operation of the first electrical machine or the second electrical machine.
Seitens des Aufbaus des Planetengetriebes hat es sich auch als zweckmäßig herausgestellt, wenn ein mit dem ersten Planetenradsatz in Zahneingriff befindliches erstes Hohlrad mit einem zweiten Planetenträger des zweiten Planetenradsatzes drehfest gekoppelt ist und/oder der erste Planetenträger des ersten Planetenradsatzes mit einem mit dem zweiten Planetenradsatz in Zahneingriff befindlichen zweiten Hohlrad drehfest gekoppelt ist.On the part of the construction of the planetary gear, it has also proven to be expedient if a first ring gear which is in mesh with the first planetary gear set is rotationally coupled to a second planet carrier of the second planetary gear set and / or the first planet carrier of the first planetary gear set is connected to the second planetary gear set in Gear meshing second ring gear is rotatably coupled.
Des Weiteren betrifft die Erfindung einen Antriebsstrang für ein Kraftfahrzeug, mit einer erfindungsgemäßen Getriebeeinheit nach einer der zuvor beschriebenen Ausführungen und einer mit der Getriebeeinheit verbundenen Antriebsachse.Furthermore, the invention relates to a drive train for a motor vehicle, with a transmission unit according to the invention according to one of the embodiments described above and a drive axle connected to the transmission unit.
Zudem betrifft die Erfindung ein Kraftfahrzeug mit einem Verbrennungsmotor, wie einem Otto- oder Dieselmotor, und diesem Antriebsstrang, wobei der Eingang der Getriebeeinheit an eine Ausgangswelle des Verbrennungsmotors angeschlossen oder anschließbar ist.In addition, the invention relates to a motor vehicle with an internal combustion engine, such as a gasoline or diesel engine, and this drive train, the input of the gear unit being connected or connectable to an output shaft of the internal combustion engine.
In anderen Worten ausgedrückt, ist somit erfindungsgemäß ein dediziertes Hybridgetriebe mit Planetenradsatz sowie einer Leistungsverzweigung realisiert. Das dedizierte Hybridgetriebe weist erfindungsgemäß einen ersten Planetenradsatz, einen zweiten Planetenradsatz, eine erste elektrische Maschine, eine zweite elektrische Maschine und Schalteinrichtungen auf. Die erste elektrische Maschine besitzt eine Generatorfunktion und ist mit einem Sonnenrad des ersten Planetenradsatzes verbunden. Die zweite elektrische Maschine besitzt eine Motorfunktion und ist mit einem Getriebeausgang (Ausgang) verbunden oder an einer Hinterachse eines Fahrzeuges angeordnet.In other words, a dedicated hybrid transmission with a planetary gear set and a power split is thus implemented according to the invention. According to the invention, the dedicated hybrid transmission has a first planetary gear set, a second planetary gear set, a first electrical machine, a second electrical machine and switching devices. The first electrical machine has a generator function and is connected to a sun gear of the first planetary gear set. The second electrical machine has a motor function and is connected to a transmission output (output) or arranged on a rear axle of a vehicle.
