Description
Die vorliegende Erfindung betrifft ein Mehrstufengetriebe mit einer Eingangswellenachse einer ersten Welle als Antrieb und einer Ausgangswellenachse einer zweiten Welle als Abtrieb, die achsversetzt zueinander angeordnet sind, wobei sechs weitere Wellen vorgesehen sind. Ferner sind zwei Stirnradstufen und zwei Planetenradsätze sowie sechs Schaltelemente vorgesehen, sodass zumindest sieben Vorwärtsgänge und zumindest ein Rückwärtsgang realisiert werden.The present invention relates to a multi-stage transmission with an input shaft axis of a first shaft as drive and an output shaft axis of a second shaft as output, which are arranged offset from one another, with six further shafts being provided. Furthermore, two spur gear stages and two planetary gear sets as well as six shifting elements are provided so that at least seven forward gears and at least one reverse gear are implemented.
Beispielsweise aus der Druckschrift
Der vorliegenden Erfindung liegt die Aufgabe zu Grunde, ein Mehrstufengetriebe der eingangs beschriebenen Gattung vorzuschlagen, welches bei maximaler Gangstufenzahl möglichst kostengünstig ist und einen möglichst geringen Bauraumbedarf aufweist.The present invention is based on the object of proposing a multi-speed transmission of the type described at the beginning, which is as cost-effective as possible with the maximum number of gear steps and which requires the least possible installation space.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruches 1 gelöst, wobei sich vorteilhafte Ausgestaltungen aus den Unteransprüchen und der Beschreibung sowie den Zeichnungen ergeben.According to the invention, this object is achieved by the features of
Somit wird ein Mehrstufengetriebe mit einer Eingangswellenachse und einer Ausgangswellenachse vorgeschlagen, die beispielsweise für eine Front- oder Heck-Queranordnung in einem Fahrzeug achsversetzt zueinander angeordnet sind. Das Mehrstufengetriebe wird somit bevorzugt mit einem seitlichen Abtrieb ausgeführt. Eine erste, als Antrieb beispielsweise mit dem Fahrzeugmotor verbundene oder verbindbare Welle ist koaxial zur Eingangswellenachse angeordnet, wobei eine zweite Welle, als Abtrieb koaxial zur Ausgangswellenachse angeordnet ist, die z.B. mit einem Abtriebsdifferential
Bei dem gleichwohl einen geringen Bauraum und einen guten Wirkungsgrad aufweisenden Mehrstufengetriebe ist ferner vorgesehen, dass die erste Welle über die erste Stirnradstufe mit einem zweiten Element des zweiten Planetenradsatzes und mit einem dritten Element des ersten Planetenradsatzes verbindbar ist, wobei die erste Welle ferner über die zweite Stirnradstufe mit einem ersten Element des ersten Planetenradsatzes und einem ersten Element des zweiten Planetenradsatzes verbindbar ist, und wobei die zweite Welle mit einem zweiten Element des ersten Planetenradsatzes und mit einem dritten Element des zweiten Planetenradsatzes verbunden ist.In the case of the multi-stage transmission, which nevertheless has a small installation space and good efficiency, it is also provided that the first shaft can be connected to a second element of the second planetary gear set and to a third element of the first planetary gear set via the first spur gear set, the first shaft also being connectable via the second Spur gear is connectable to a first element of the first planetary gear set and a first element of the second planetary gear set, and wherein the second shaft is connected to a second element of the first planetary gear set and to a third element of the second planetary gear set.
Das vorgeschlagene Mehrstufengetriebe umfasst somit nur zwei Planetenradsatzebenen und zwei Stirnradstufen sowie sechs Schaltelemente, wobei zum Realisieren der Gangstufen gleichzeitig drei der Schaltelemente geschlossen bzw. aktiviert sind. Unabhängig von den verschiedenen Ausführungsvarianten des Mehrstufengetriebes ergibt sich eine insgesamt kompakte Bauweise mit geringer Bauteilbelastung und geringen Getriebeverlusten sowie gutem Verzahnungswirkungsgrad und zudem eine gute Übersetzungsreihe, wobei eine konstruktiv einfache Anbindung zumindest einer elektrischen Maschine zur Hybridisierung des Mehrstufengetriebes möglich ist. Vorzugsweise eignet sich eine der Stirnradstufen zum achsparallelen Anbinden der elektrischen Maschine. Es ist auch möglich, dass bei Bedarf eine koaxiale Anbindung der elektrischen Maschine z.B. an der ersten Welle vorgesehen ist.The proposed multi-stage transmission thus comprises only two planetary gear set levels and two spur gear stages as well as six shifting elements, with three of the shifting elements being closed or activated at the same time in order to realize the gear steps. Independent of the different design variants of the multi-speed transmission, the result is an overall compact design with low component load and low transmission losses as well as good gear efficiency and also a good gear ratio, whereby a structurally simple connection of at least one electric machine for hybridizing the multi-speed transmission is possible. One of the spur gear stages is preferably suitable for axially parallel connection of the electrical machine. It is also possible, if necessary, to provide a coaxial connection to the electrical machine, e.g. on the first shaft.
Sollte jedoch eine noch größere Übersetzung oder ein aus Bauraumgründen größerer Achsabstand zwischen der elektrischen Maschine und den Eingangs- und Ausgangswellenachsen gewünscht werden, kann auch eine weitere Übersetzungsstufe bzw. ein Zwischengetriebe zum Anbinden der elektrischen Maschine vorgesehen sein. Wenn die elektrische Maschine fest zum Antrieb übersetzt ist, können sämtliche verbrennungsmotorischen Gänge auch elektrisch realisiert werden.If, however, an even larger translation or a larger center distance between the electrical machine and the input and output shaft axes for reasons of installation space is desired, a further translation stage or an intermediate gear can also be provided for connecting the electrical machine. If the electric machine is geared towards the drive, all internal combustion engine gears can also be implemented electrically.
Dem Mehrstufengetriebe bzw. der ersten Welle des Mehrstufengetriebes kann beispielsweise eine Drehschwingungs-Entkopplungseinheit vorgeschaltet sein. Im Falle einer Hybridisierung ist zwischen der elektrischen Maschine und dem Verbrennungsmotor vorzugsweise ein zusätzliches Schaltelement als Trennkupplung positioniert, mit dem der Verbrennungsmotor bzw. der Antriebsmotor des Fahrzeuges von der ersten Welle entkoppelbar ist. Auf diese Weise ist auch sowohl rein verbrennungsmotorisches Fahren als auch rein elektrisches Fahren möglich. Im Falle der Hybridisierung eignet sich bevorzugt ein drittes Schaltelement oder eine erste Alternative des dritten Schaltelements als internes Anfahrelement (IAE).For example, a torsional vibration decoupling unit can be connected upstream of the multi-stage transmission or the first shaft of the multi-stage transmission. In the case of hybridization, an additional switching element is preferably positioned as a separating clutch between the electric machine and the internal combustion engine, with which the internal combustion engine or the drive motor of the vehicle can be decoupled from the first shaft. In this way, both purely internal combustion engine driving and purely electric driving are possible. In the case of hybridization, a third switching element or a first alternative of the third switching element is preferably suitable as an internal starting element (IAE).
Als Schaltelemente können sowohl reib- als auch formschlüssige Schaltelemente eingesetzt werden. Vorzugsweise können aufgrund ihrer Charakteristik vor allem ein als Bremse ausgeführtes erstes Schaltelement oder eine erste Alternative des ersten Schaltelements und/oder ein sechstes Schaltelement oder eine erste Alternative des sechsten Schaltelements und/oder die Trennkupplung als formschlüssiges Klauenschaltelement ausgeführt werden.Both frictional and form-fitting switching elements can be used as switching elements. Preferably, due to their characteristics, a first switching element designed as a brake or a first alternative to the first Switching element and / or a sixth switching element or a first alternative of the sixth switching element and / or the separating clutch are designed as a form-fitting claw switching element.
Bei der vorliegenden Erfindung können beide Planetenradsätze als Minus-Planetenradsatz ausgeführt sein. Ferner ist es möglich, dass der zweite Planetenradsatz auch als Plus-Planetenradsatz ausgeführt sein kann. Ein Minus-Planetenradsatz kann bevorzugt in einen Plus-Planetenradsatz überführt werden, wenn die Planetenträger- und die Hohlradanbindung an diesem Radsatz miteinander vertauscht wird und der Betrag der Standübersetzung um 1 erhöht wird. Dies bedeutet für den Fachmann, dass bei einem Minus-Planetenradsatz ein erstes Element als Sonnenrad, ein zweites Element als Planetenradträger oder Steg und ein drittes Element als Hohlrad ausgeführt sind. Bei einem Plus-Planetenradsatz gilt jedoch, dass ein erstes Element als Sonnenrad, ein zweites Element als Hohlrad und ein drittes Element als Steg bzw. Planetenradträger ausgeführt sind. Anhand dieser Angaben kann beispielsweise ein vorgesehener Minus-Planetenradsatz bei dem erfindungsgemäßen Mehrstufengetriebe in einen Plus-Planetenradsatz umgewandelt werden.In the present invention, both planetary gear sets can be designed as a minus planetary gear set. It is also possible for the second planetary gear set to be designed as a plus planetary gear set. A minus planetary gear set can preferably be converted into a plus planetary gear set if the planet carrier and ring gear connection on this gear set are interchanged and the amount of the stationary gear ratio is increased by 1. For those skilled in the art, this means that in a minus planetary gear set, a first element is designed as a sun gear, a second element as a planetary gear carrier or web and a third element as a ring gear. In the case of a plus planetary gear set, however, a first element is designed as a sun gear, a second element as a ring gear and a third element as a web or planetary gear carrier. On the basis of this information, for example, a provided minus planetary gear set can be converted into a plus planetary gear set in the multi-step transmission according to the invention.
Ein Minus-Planetenradsatz weist bekanntlich an seinem Planetenradträger verdrehbar gelagerte Planetenräder auf, die mit dem Sonnenrad und dem Hohlrad dieses Planetenradsatzes kämmen, so dass sich das Hohlrad bei festgehaltenem Planetenradträger und drehendem Sonnenrad in zur Sonnenraddrehrichtung entgegengesetzter Richtung dreht. Ein Plus-Planetenradsatz weist bekanntlich an seinem Planetenradträger verdrehbar gelagerte und miteinander in Zahneingriff stehende innere und äußere Planetenräder auf, wobei das Sonnenrad dieses Planetenradsatzes mit den inneren Planetenrädern und das Hohlrad dieses Planetenradsatzes mit den äußeren Planetenrädern kämmen, so dass sich das Hohlrad bei festgehaltenem Planetenradträger und drehendem Sonnenrad in zur Sonnenraddrehrichtung gleicher Richtung dreht.As is well known, a minus planetary gear set has planetary gears mounted rotatably on its planetary gear carrier, which mesh with the sun gear and the ring gear of this planetary gear set, so that the ring gear rotates in the opposite direction to the sun gear when the planetary gear carrier is held and the sun gear is rotating. As is well known, a plus planetary gear set has inner and outer planetary gears mounted rotatably on its planetary gear carrier and meshing with one another, the sun gear of this planetary gear set meshing with the inner planetary gears and the ring gear of this planetary gear set meshing with the outer planetary gears, so that the ring gear meshes with the planetary gear carrier held in place and the rotating sun gear rotates in the same direction as the sun gear rotating direction.
