Description
Die Erfindung betrifft ein Getriebe für ein Kraftfahrzeug, sowie einen Antriebsstrang für ein Kraftfahrzeug mit einem solchen Getriebe. Ein Getriebe bezeichnet hier insbesondere ein mehrgängiges Getriebe, bei dem eine Vielzahl von Gängen, also feste Übersetzungsverhältnisse zwischen der Antriebswelle und der Abtriebswelle des Getriebes, durch Schaltelemente vorzugsweise automatisch schaltbar sind. Bei den Schaltelementen handelt es sich hier beispielsweise um Kupplungen oder Bremsen. Derartige Getriebe finden vor allem in Kraftfahrzeugen Anwendung, um die Drehzahl- und Drehmomentabgabecharakteristik der Antriebseinheit den Fahrwiderständen des Fahrzeugs in geeigneter Weise anzupassen.The invention relates to a transmission for a motor vehicle, as well as a drive train for a motor vehicle with such a transmission. A transmission referred to here in particular a multi-speed transmission in which a plurality of gears, so fixed ratios between the drive shaft and the output shaft of the transmission, are preferably automatically switched by switching elements. The switching elements are, for example, clutches or brakes here. Such transmissions are mainly used in motor vehicles to adapt the speed and torque output characteristics of the drive unit to the driving resistance of the vehicle in a suitable manner.
Die Patentanmeldung
Es ist Aufgabe der Erfindung, eine alternative Ausführung zu dem im eingangs genannten Stand der Technik offenbarten Getriebe anzugeben.It is an object of the invention to provide an alternative embodiment to the disclosed in the aforementioned prior art transmission.
Die Aufgabe wird gelöst durch die Merkmale des Patentanspruchs 1. Vorteilhafte Ausgestaltungen ergeben sich aus den Unteransprüchen, der Beschreibung sowie aus den Figuren.The object is solved by the features of
Das Getriebe umfasst eine Antriebswelle, eine Abtriebswelle, einen ersten und zweiten Planetenradsatz, welche koaxial zur Antriebswelle angeordnet sind, einen dritten und vierten Planetenradsatz, welche achsparallel zur Antriebswelle angeordnet sind, eine erste und zweite Stirnradstufe sowie sechs Schaltelemente. Die erste und zweite Stirnradstufe weisen je ein erstes und zweites Stirnrad auf, welche miteinander kämmen.The transmission comprises a drive shaft, an output shaft, a first and second planetary gear set, which are arranged coaxially to the drive shaft, a third and fourth planetary gear, which are arranged axially parallel to the drive shaft, a first and second spur gear and six switching elements. The first and second spur gear each have a first and second spur gear, which mesh with each other.
Ein Planetenradsatz kann als Minus-Radsatz oder als Plus-Radsatz aufgebaut sein. Ein Minus-Radsatz bezeichnet einen Planetenradsatz mit einem Steg, an dem die Planetenräder drehbar gelagert sind, mit einem Sonnenrad und mit einem Hohlrad, wobei die Verzahnung zumindest eines der Planetenräder sowohl mit der Verzahnung des Sonnenrades, als auch mit der Verzahnung des Hohlrades kämmt, wodurch das Hohlrad und das Sonnenrad in entgegengesetzte Drehrichtungen rotieren, wenn das Sonnenrad bei feststehendem Steg rotiert. Ein Plus-Radsatz unterscheidet sich zu dem gerade beschriebenen Minus-Planetenradsatz dahingehend, dass der Plus-Radsatz innere und äußere Planetenräder aufweist, welche drehbar an dem Steg gelagert sind. Die Verzahnung der inneren Planetenräder kämmt dabei einerseits mit der Verzahnung des Sonnenrads und andererseits mit der Verzahnung der äußeren Planetenräder. Die Verzahnung der äußeren Planetenräder kämmt darüber hinaus mit der Verzahnung des Hohlrades. Dies hat zur Folge, dass bei feststehendem Steg das Hohlrad und das Sonnenrad in die gleiche Drehrichtung rotieren. Wird ein Minus-Radsatz durch einen Plus-Radsatz ersetzt, so ist neben der veränderten Anbindung der Elemente Steg und Hohlrad der Betrag der Standgetriebeübersetzung um den Wert Eins zu erhöhen, um dieselbe Übersetzungswirkung zu erzielen.A planetary gear set can be constructed as a minus wheel set or as a plus wheel set. A minus wheel set denotes a planetary gear set with a web on which the planet gears are rotatably mounted, with a sun gear and with a ring gear, wherein the toothing of at least one of the planetary gears meshes with both the teeth of the sun gear, and with the teeth of the ring gear, whereby the ring gear and the sun gear rotate in opposite directions of rotation when the sun gear rotates at a fixed web. A plus gear set differs from the negative planetary gear set just described in that the plus gear set has inner and outer planet gears rotatably supported on the land. The toothing of the inner planet gears meshes on the one hand with the teeth of the sun gear and on the other hand with the teeth of the outer planetary gears. The toothing of the outer planetary gears also meshes with the teeth of the ring gear. This has the consequence that rotate at a fixed land, the ring gear and the sun gear in the same direction. If a minus wheel set is replaced by a plus wheel set, in addition to the changed connection of the elements bridge and ring gear, the amount of the stationary gear ratio by the value of one to increase to achieve the same translation effect.
Die vier Planetenradsätze weisen je ein erstes Element, ein zweites Element und ein drittes Element auf. Das erste Element wird durch ein Sonnenrad des jeweiligen Planetenradsatzes gebildet. Das zweite Element wird durch einen Steg, und das dritte Element durch ein Hohlrad des jeweiligen Planetenradsatzes gebildet, sofern dieser als Minus-Radsatz ausgebildet ist. Ist der jeweilige Planetenradsatz hingegen als ein Plus-Radsatz ausgebildet, so wird dessen zweites Element durch das Hohlrad, und dessen drittes Element durch den Steg gebildet.The four planetary gear sets each have a first element, a second element and a third element. The first element is formed by a sun gear of the respective planetary gear set. The second element is formed by a web, and the third element by a ring gear of the respective planetary gear set, if this is designed as a minus wheel set. If the respective planetary gear set, however, formed as a plus-wheel, so its second element is formed by the ring gear, and the third element through the web.
Erfindungsgemäß ist die Antriebswelle mit dem ersten Stirnrad der zweiten Stirnradstufe ständig oder schaltbar verbunden. Das erste Element des ersten Planetenradsatzes ist mit dem dritten Element des zweiten Planetenradsatzes ständig verbunden. Das zweite Element des zweiten Planetenradsatzes ist mit dem zweiten Element des ersten Planetenradsatzes und mit dem ersten Stirnrad der ersten Stirnradstufe ständig verbunden. Das erste Element des dritten Planetenradsatzes ist mit dem ersten Element des vierten Planetenradsatzes ständig verbunden. Das dritte Element des dritten Planetenradsatzes ist mit dem zweiten Element des vierten Planetenradsatzes ständig verbunden. Die Abtriebswelle ist mit dem zweiten Element des dritten Planetenradsatzes ständig verbunden. Das dritte Element des vierten Planetenradsatzes ist mit dem zweiten Stirnrad der ersten Stirnradstufe ständig verbunden.According to the invention, the drive shaft is permanently or switchably connected to the first spur gear of the second spur gear stage. The first element of the first planetary gear set is permanently connected to the third element of the second planetary gear set. The second element of the second planetary gear set is permanently connected to the second element of the first planetary gear set and to the first spur gear of the first spur gear stage. The first element of the third planetary gear set is permanently connected to the first element of the fourth planetary gear set. The third element of the third planetary gear set is permanently connected to the second element of the fourth planetary gear set. The output shaft is permanently connected to the second element of the third planetary gear set. The third element of the fourth planetary gear set is permanently connected to the second spur gear of the first spur gear.
Durch Schließen des ersten Schaltelements ist die Antriebswelle mit dem ersten Element des ersten Planetenradsatzes verbindbar. Durch Schließen des zweiten Schaltelements ist die Antriebswelle mit dem ersten Element des zweiten Planetenradsatzes verbindbar. Durch Schließen des dritten Schaltelements ist das erste Element des zweiten Planetenradsatzes drehfest festsetzbar. Durch Schließen des vierten Schaltelements ist das dritte Element des ersten Planetenradsatzes drehfest festsetzbar. Durch Schließen des fünften Schaltelements ist das erste Element des dritten Planetenradsatzes drehfest festsetzbar. Durch Schließen des sechsten Schaltelements ist die Antriebswelle mit dem zweiten Element des vierten Planetenradsatzes verbindbar, wobei diese Wirkverbindung über die zweite Stirnradstufe führt.By closing the first Switching element, the drive shaft with the first element of the first planetary gear set is connectable. By closing the second switching element, the drive shaft with the first element of the second planetary gear set is connectable. By closing the third switching element, the first element of the second planetary gear set is rotatably fixed. By closing the fourth switching element, the third element of the first planetary gear set is rotatably fixable. By closing the fifth switching element, the first element of the third planetary gear set is rotatably fixable. By closing the sixth switching element, the drive shaft can be connected to the second element of the fourth planetary gear set, wherein this operative connection leads via the second spur gear stage.
Durch selektives Schließen der sechs Schaltelemente sind neun Gangstufen zwischen der Antriebswelle und der Abtriebswelle darstellbar. Eine erste Gangstufe ergibt sich durch Schließen des ersten, vierten und fünften Schaltelements. Eine zweite Gangstufe ergibt sich durch Schließen des ersten, dritten und fünften Schaltelements. Eine dritte Gangstufe ergibt sich durch Schließen des ersten, zweiten und fünften Schaltelements. Eine vierte Gangstufe ergibt sich durch Schließen von zumindest des fünften und sechsten Schaltelements. Vorzugsweise ist in der vierten Gangstufe zusätzlich das erste Schaltelement geschlossen. Eine fünfte Gangstufe ergibt sich durch Schließen des ersten, zweiten und sechsten Schaltelements. Eine sechste Gangstufe ergibt sich durch Schließen des ersten, dritten und sechsten Schaltelements. Eine siebente Gangstufe ergibt sich durch Schließen des ersten, vierten und sechsten Schaltelements. Eine achte Gangstufe ergibt sich durch Schließen des dritten, vierten und sechsten Schaltelements. Eine neunte Gangstufe ergibt sich durch Schließen des zweiten, vierten und sechsten Schaltelements.By selective closing of the six switching elements nine gear stages between the drive shaft and the output shaft can be displayed. A first gear is obtained by closing the first, fourth and fifth switching element. A second gear is obtained by closing the first, third and fifth switching element. A third gear is obtained by closing the first, second and fifth switching element. A fourth gear is obtained by closing at least the fifth and sixth shifting elements. Preferably, in the fourth gear, in addition, the first switching element is closed. A fifth gear is obtained by closing the first, second and sixth switching element. A sixth gear is obtained by closing the first, third and sixth shift element. A seventh gear stage is obtained by closing the first, fourth and sixth shifting element. An eighth gear step results from closing the third, fourth and sixth shift elements. A ninth speed step results from closing the second, fourth and sixth shift elements.
Eine Gangstufe mit im Vergleich zur ersten Gangstufe veränderter Drehrichtung der Abtriebswelle kann durch Schließen des zweiten, vierten und fünften Schaltelements erreicht werden. Eine derartige Gangstufe ist im Kraftfahrzeug zur Bereitstellung eines Rückwärtsganges geeignet.A gear stage with changed compared to the first gear speed direction of rotation of the output shaft can be achieved by closing the second, fourth and fifth switching element. Such a gear is suitable in the motor vehicle for providing a reverse gear.
Ist der zweite Planetenradsatz als ein Minus-Radsatz ausgebildet, so ist das Hohlrad des zweiten Planetenradsatzes vorzugsweise am Innendurchmesser des Sonnenrades des ersten Planetenradsatzes ausgebildet. Dadurch kann das Getriebe in axialer Richtung besonders kompakt gestaltet werden.If the second planetary gear set is designed as a minus wheel set, the ring gear of the second planetary gear set is preferably formed on the inner diameter of the sun gear of the first planetary gear set. This allows the transmission to be made particularly compact in the axial direction.
Gemäß einer bevorzugten Ausgestaltung sind das fünfte und sechste Schaltelement koaxial zum dritten und vierten Planetenradsatz angeordnet. Gemäß einer alternativen Ausgestaltung ist von den sechs Schaltelementen nur das fünfte Schaltelement koaxial zum dritten und vierten Planetenradsatz angeordnet.According to a preferred embodiment, the fifth and sixth switching element are arranged coaxially with the third and fourth planetary gear. According to an alternative embodiment of the six switching elements, only the fifth switching element is arranged coaxially with the third and fourth planetary gear.
Vorzugsweise weist das Getriebe eine elektrische Maschine mit einem drehfesten Stator und einem drehbaren Rotor auf, wobei der Rotor mit der Antriebswelle ständig oder schaltbar verbunden ist. Die Anbindung des Rotors an die Antriebswelle ermöglicht die Nutzung sämtlicher Gangstufen des Getriebes bei Antrieb mittels der elektrischen Maschine. Die elektrische Maschine kann auch separat vom Getriebe ausgebildet, und mit diesem über eine geeignete Schnittstelle verbunden sein.Preferably, the transmission has an electric machine with a rotationally fixed stator and a rotatable rotor, wherein the rotor is permanently or switchably connected to the drive shaft. The connection of the rotor to the drive shaft allows the use of all gear ratios of the transmission when driven by the electric machine. The electric machine can also be formed separately from the transmission, and be connected to this via a suitable interface.
Gemäß einer bevorzugten Ausgestaltung ist die elektrische Maschine koaxial zur Antriebswelle angeordnet. Gemäß einer alternativen Ausgestaltung ist die elektrische Maschine achsparallel zur Antriebswelle angeordnet, wobei der Rotor der elektrischen Maschine über einen ein- oder mehrstufigen Stirnradtrieb oder über einen Kettentrieb mit der Antriebswelle ständig oder schaltbar verbunden ist.According to a preferred embodiment, the electric machine is arranged coaxially to the drive shaft. According to an alternative embodiment, the electric machine is arranged axially parallel to the drive shaft, wherein the rotor of the electric machine via a single or multi-stage spur gear or via a chain drive with the drive shaft is constantly or switchably connected.
Vorzugsweise umfasst das Getriebe eine Anschlusswelle, welche eine drehmomentübertragende Schnittstelle zu eine getriebe-externen Antriebseinheit aufweist, beispielsweise zu einem Verbrennungsmotor. Die Anschlusswelle ist durch Schließen einer Trennkupplung mit der Antriebswelle verbindbar. Die Anschlusswelle weist bevorzugt zwei Abschnitte auf, welche durch zumindest einen Torsionsschwingungsdämpfer miteinander verbunden sind.Preferably, the transmission comprises a connection shaft, which has a torque-transmitting interface to a transmission-external drive unit, for example to an internal combustion engine. The connecting shaft can be connected to the drive shaft by closing a separating clutch. The connecting shaft preferably has two sections, which are interconnected by at least one torsional vibration damper.
Das Getriebe kann Bestandteil eines Antriebsstrangs eines Kraftfahrzeugs sein. Der Antriebsstrang weist neben dem Getriebe auch einen Verbrennungsmotor auf, welche über den getriebe-internen oder einen getriebe-externen Torsionsschwingungsdämpfer mit der Antriebswelle des Getriebes drehelastisch verbunden, bzw. verbindbar sein kann. Die Abtriebswelle des Getriebes ist mit einem getriebe-internen oder getriebe-externen Differentialgetriebe antriebswirkverbunden, welches mit Rädern des Kraftfahrzeugs wirkverbunden ist. Weist das Getriebe die elektrische Maschine auf, so ermöglicht der Antriebsstrang mehrere Antriebsmodi des Kraftfahrzeugs. In einem elektrischen Fahrbetrieb wird das Kraftfahrzeug von der elektrischen Maschine des Getriebes angetrieben. In einem verbrennungsmotorischen Betrieb wird das Kraftfahrzeug vom Verbrennungsmotor angetrieben. In einem hybridischen Betrieb wird das Kraftfahrzeug sowohl vom Verbrennungsmotor als auch von der elektrischen Maschine des Getriebes angetrieben.The transmission may be part of a drive train of a motor vehicle. In addition to the transmission, the drive train also has an internal combustion engine, which can be rotationally elastically connected or connectable to the drive shaft of the transmission via the transmission-internal or a transmission-external torsional vibration damper. The output shaft of the transmission is drivirkgetrunden with a gear-internal or gear-external differential gear, which is operatively connected to wheels of the motor vehicle. If the transmission has the electric machine, the drive train enables a plurality of drive modes of the motor vehicle. In an electric driving operation, the motor vehicle is driven by the electric machine of the transmission. In an internal combustion engine operation, the motor vehicle is driven by the internal combustion engine. In a hybrid operation, the motor vehicle is driven by both the engine and the electric machine of the transmission.
Eine ständige Verbindung wird als Verbindung zwischen zwei Elementen bezeichnet, die stets besteht. Derart ständig verbundene Elemente drehen stets mit der gleichen Abhängigkeit zwischen deren Drehzahlen. In einer ständigen Verbindung zwischen zwei Elementen kann sich kein Schaltelement befinden. Eine ständige Verbindung ist daher von einer schaltbaren Verbindung zu unterscheiden. Eine ständig drehfeste Verbindung wird als Verbindung zwischen zwei Elementen bezeichnet, die stets besteht und deren verbundene Elemente somit stets die gleiche Drehzahl aufweisen.A permanent connection is called a connection between two elements that always exists. Such constantly connected elements always rotate with the same dependence between their speeds. In a permanent connection between two elements, no switching element can be located. A permanent connection must therefore be distinguished from a switchable connection. A permanently non-rotatable connection is referred to as a connection between two elements, which always exists and their connected elements thus always have the same speed.
Unter dem Begriff „Schließen eines Schaltelements“ wird im Zusammenhang mit der Gangbildung ein Vorgang verstanden, bei dem das Schaltelement so angesteuert wird, dass es am Ende des Schließvorgangs ein hohes Maß an Drehmoment überträgt. Während formschlüssige Schaltelemente im „geschlossenen“ Zustand keine Differenzdrehzahl zulassen, ist bei kraftschlüssigen Schaltelementen im „geschlossenen“ Zustand die Ausbildung einer geringen Differenzdrehzahl zwischen den Schaltelementhälften gewollt oder ungewollt möglich.The term "closing a switching element" is understood in connection with the formation of a process in which the Switching element is driven so that it transmits a high degree of torque at the end of the closing process. While positive switching elements in the "closed" state do not allow differential speed, the formation of a low differential speed between the switching element halves is intentionally or unintentionally possible with non-positive switching elements in the "closed" state.
