Definitions

  • the present invention relates to a transmission with an electric motor, in particular a transmission for a motor vehicle, wherein the transmission has at least one input shaft and at least one output shaft, wherein the output shaft is operatively connected to a differential, wherein a first idler gear and a second idler gear arranged on the output shaft are.
  • the object of the invention is therefore to inexpensively improve a transmission without having to accept losses in terms of functions, package, efficiency, etc.
  • the transmission can be extended by an electric motor in a particularly simple and cost-effective manner.
  • the electric motor can be decoupled from the transmission, so that an outgoing from the electric motor drag torque does not necessarily have to be dragged.
  • the clutch is in the form of a synchronizer clutch, so that the addition of the electric motor can be done to the transmission via the existing transmission circuit.
  • the operative connection between the electric motor and the first idler gear can be made via a direct connection, in which a pinion of the electric motor is in direct meshing engagement with the first idler gear.
  • first idler gear is operatively connected by means of a Losradkupplung with the second idler gear.
  • This idler clutch is designed such that a rotationally fixed connection between two idler gears can be produced.
  • the drive power of the electric motor can be introduced in different ways in the transmission. Just as well, it is conceivable that when establishing an operative connection between the first idler gear and the output shaft, an electromotive forward gear is guaranteed under stress of the drive power of the electric motor, while setting up an operative connection between the first idler gear and second idler gear another electromotive forward gear can be established.
  • the second idler gear is a reverse gear, which can be brought into operative connection via the idler clutch with the electric motor at the same time.
  • the idler gear is a synchronizer clutch and switchable by means of a conventional transmission circuit

  • the electric motor is operatively connected to the third idler gear of the output shaft.
  • the electric motor can be connected via two gear ratios to the output shaft.
  • the second idler gear is operatively connected to the input shaft, since a stand-by function can be ensured by this measure. If the first idler gear and the second idler gear are operatively connected by means of the clutch, the input shaft, the second idler gear, the idler gear clutch, the first idler gear and thus also the electric motor can be driven by means of an internal combustion engine drive power.

Description

Getriebe  transmission
Die vorliegende Erfindung betrifft ein Getriebe mit einem Elektromotor, insbesondere ein Getriebe für ein Kraftfahrzeug, wobei das Getriebe zumindest eine Eingangswelle und zumindest eine Abtriebswelle aufweist, wobei die Abtriebswelle mit einem Differential wirkverbunden ist, wobei ein erstes Losrad und ein zweites Losrad auf der Abtriebswelle angeordnet sind. The present invention relates to a transmission with an electric motor, in particular a transmission for a motor vehicle, wherein the transmission has at least one input shaft and at least one output shaft, wherein the output shaft is operatively connected to a differential, wherein a first idler gear and a second idler gear arranged on the output shaft are.
Getriebe der eingangs genannten Art sind hinlänglich bekannt, jedoch in Ihren Funktionen stark eingeschränkt, sofern eine kostengünstige Lösung angestrebt wird. Transmissions of the type mentioned are well known, but severely limited in their functions, if a cost-effective solution is sought.
Aufgabe der Erfindung ist es daher, ein Getriebe kostengünstig zu verbessern, ohne Einbußen hinsichtlich Funktionen, Package, Wirkungsgrad usw. hinnehmen zu müssen. The object of the invention is therefore to inexpensively improve a transmission without having to accept losses in terms of functions, package, efficiency, etc.
Die Aufgaben werden durch den Hauptanspruch gelöst. Die Unteransprüche zeigen vorteilhafte Aus führungs formen. The tasks are solved by the main claim. The dependent claims show advantageous embodiments.
Ist der Elektromotor mit dem ersten Losrad wirkverbunden und das erste Losrad mittels einer Schaltkupplung mit der Abtriebswelle wirkverbindbar, kann das Getriebe besonders einfach und kostengünstig um einen Elektromotor erweitert werden. Mittels der If the electric motor is operatively connected to the first idler gear and the first idler gear can be operatively connected to the output shaft by means of a clutch, the transmission can be extended by an electric motor in a particularly simple and cost-effective manner. By means of
Schaltkupplung kann der Elektromotor von dem Getriebe entkoppelt werden, sodass ein von dem Elektromotor ausgehendes Schleppmoment nicht zwingend mitgeschleppt werden muss. Die Schaltkupplung ist in Form einer Synchronkupplung ausgebildet, sodass das Hinzuschalten des Elektromotors an das Getriebe über die vorhandene Getriebeschaltung erfolgen kann. Die Wirkverbindung zwischen Elektromotor und dem ersten Losrad kann über eine direkte Verbindung hergestellt werden, in dem ein Ritzel des Elektromotors in direktem Zahneingriff mit dem ersten Losrad steht. Es ist jedoch auch möglich, mithilfe eines Zwischenrads oder mehreren Zwischenrädern eine indirekte Verbindung zwischen Ritzel des Elektromotors und dem ersten Losrad herzustellen, sodass durch diese Maßnahme beispielsweise eine Drehzahlreduktion der elektromotorischen Antriebsleistung erfolgen kann. Clutch, the electric motor can be decoupled from the transmission, so that an outgoing from the electric motor drag torque does not necessarily have to be dragged. The clutch is in the form of a synchronizer clutch, so that the addition of the electric motor can be done to the transmission via the existing transmission circuit. The operative connection between the electric motor and the first idler gear can be made via a direct connection, in which a pinion of the electric motor is in direct meshing engagement with the first idler gear. However, it is also possible to produce by means of an intermediate or more intermediate wheels an indirect connection between the pinion of the electric motor and the first idler gear, so that through this Measure example, a speed reduction of the electromotive drive power can be done.
Von weiterem Vorteil ist es, wenn das erste Losrad mittels einer Losradkupplung mit dem zweiten Losrad wirkverbindbar ist. Diese Losradkupplung ist derart ausgebildet, dass eine drehfeste Verbindung zwischen zwei Losrädern herstellbar ist. Hierdurch ergibt sich eine weitere Anbindungsmöglichkeit des Elektromotors an das Getriebe. Die Antriebsleistung des Elektromotors kann auf unterschiedlichen Wegen in das Getriebe eingeleitet werden. Genauso gut ist es vorstellbar, dass bei Einrichtung einer Wirkverbindung zwischen dem ersten Losrad und der Abtriebswelle eine elektromotorische Vorwärtsgangstufe unter Beanspruchung der Antriebsleistung des Elektromotors gewährleistet ist, während bei Einrichtung einer Wirkverbindung zwischen erstem Losrad und zweitem Losrad eine weitere elektromotorische Vorwärtsgangstufe eingerichtet werden kann. Another advantage is when the first idler gear is operatively connected by means of a Losradkupplung with the second idler gear. This idler clutch is designed such that a rotationally fixed connection between two idler gears can be produced. This results in a further connection possibility of the electric motor to the transmission. The drive power of the electric motor can be introduced in different ways in the transmission. Just as well, it is conceivable that when establishing an operative connection between the first idler gear and the output shaft, an electromotive forward gear is guaranteed under stress of the drive power of the electric motor, while setting up an operative connection between the first idler gear and second idler gear another electromotive forward gear can be established.
Vorzugsweise ist das zweite Losrad ein Rückwärtsganglosrad, welches gleichzeitig über die Losradkupplung mit dem Elektromotor in Wirkverbindung gebracht werden kann. Preferably, the second idler gear is a reverse gear, which can be brought into operative connection via the idler clutch with the electric motor at the same time.
Vorzugsweise ist die Losradkupplung eine Synchronkupplung und mittels einer herkömmlichen Getriebeschaltung schaltbar Preferably, the idler gear is a synchronizer clutch and switchable by means of a conventional transmission circuit
Eine besondere Ausgestaltung sieht vor, dass die Schaltkupplung als eine zweiseitig schaltbare Synchronkupplung ausgebildet ist, wodurch nicht nur das erste Losrad, sondern auch ein weiteres, drittes Losrad mit der Abtriebswelle wirkverbindbar ist. So kann die vorhandene Schaltkupplung doppelt genutzt werden, was ohne großem Mehraufwand die Gangzahl des Getriebes erhöht. A particular embodiment provides that the clutch is designed as a two-sided switchable synchronizer clutch, whereby not only the first idler gear, but also another, third idler gear is operatively connected to the output shaft. Thus, the existing clutch can be used twice, which increases the gear ratio of the transmission without much additional effort.
Ferner ist es von Vorteil, wenn der Elektromotor mit dem dritten Losrad der Abtriebswelle wirkverbunden ist. Hiermit kann der Elektromotor über zwei Übersetzungsstufen an die Abtriebswelle angebunden werden. Besonders vorteilhaft ist es, wenn das zweite Losrad mit der Eingangswelle wirkverbunden ist, da durch diese Maßnahme eine Standladefunktion gewährleistet werden kann. Sind das erste Losrad und das zweite Losrad mittels der Schaltkupplung wirkverbunden können mittels einer verbrennungsmotorischer Antriebsleistung die Eingangswelle, das zweite Losrad, die Losradkupplung, das erste Losrad und somit auch der Elektromotor angetrieben werden. Furthermore, it is advantageous if the electric motor is operatively connected to the third idler gear of the output shaft. Hereby, the electric motor can be connected via two gear ratios to the output shaft. It is particularly advantageous if the second idler gear is operatively connected to the input shaft, since a stand-by function can be ensured by this measure. If the first idler gear and the second idler gear are operatively connected by means of the clutch, the input shaft, the second idler gear, the idler gear clutch, the first idler gear and thus also the electric motor can be driven by means of an internal combustion engine drive power.
Ferner ist vorteilhaft, wenn das Getriebe eine weitere Abtriebswelle bzw. zweite It is also advantageous if the transmission has a further output shaft or second
Abtriebswelle aufweist, wodurch eine besonders axial kompakte Bauweise realisiert werden kann. Has output shaft, whereby a particularly axially compact design can be realized.
Ferner ist es von Vorteil, wenn ein Verbrennungsmotor ausschließlich mit der weiteren bzw. zweiten Abtriebswelle wirkverbindbar ist, um eine verbrennungsmotorische Furthermore, it is advantageous if an internal combustion engine is operatively connected exclusively to the further or second output shaft to an internal combustion engine
Vorwärtsgangstufe einzurichten. Von besonderem Vorteil ist es, wenn darüber hinaus der Elektromotor ausschließlich mit der Abtriebs welle bzw. der ersten Abtriebswelle wirkverbindbar ist, um eine elektromotorische Gangstufe einzurichten. Die To set forward gear. It is particularly advantageous if, in addition, the electric motor is operatively connected exclusively with the output shaft or the first output shaft to set up an electric motor gear ratio. The
elektromotorische Gangstufe kann je nach Drehrichtung des Elektromotors als elektromotorische Vorwärts- oder Rückwärtsgangstufe genutzt werden. Die Electromotive gear can be used depending on the direction of rotation of the electric motor as an electric motor forward or reverse gear. The
verbrennungsmotorischen Vorwärtsgangstufen und die elektromotorischen Gangstufen können getrennt oder in Kombination eingerichtet werden, um beispielsweise einen rein elektrischen Betrieb, einen rein verbrennungsmotorischen Betrieb oder einen Combustion engine forward gear ratios and the electromotive gear ratios can be set up separately or in combination to, for example, a purely electrical operation, a pure combustion engine operation or a
Hybridbetrieb einzurichten. Set up hybrid operation.
Mit dieser bevorzugten Ausgestaltung wird erreicht, dass die Antriebsleistung des Verbrennungsmotors und die Antriebsleistung des Elektromotors in einem Hybridbetrieb erst an dem Zahnkranz des Differentials zusammentreffen und sich dort addieren. Das hat zur Folge, dass jene Zahnräder, die im Leistungsfluss eines verbrennungsmotorischen Vorwärtsgangs liegen, keiner zusätzlichen Antriebsleistung, nämlich die des With this preferred embodiment it is achieved that the drive power of the internal combustion engine and the drive power of the electric motor in a hybrid operation first meet at the sprocket of the differential and add up there. This has the consequence that those gears that are in the power flow of a combustion engine forward gear, no additional drive power, namely that of the
Elektromotors, ausgesetzt sind. Es entfällt somit eine Anpassung der Zahnräder in Form von breiter ausgeführten Zahnrädern, die dazu in der Lage wären, größere Drehmomente zu übertragen. Electric motor, are exposed. It thus eliminates an adaptation of the gears in shape wider gear wheels that would be able to transmit larger torques.
In anderen Worten ausgedrückt ist die Abtriebswelle frei von Zahnrädern, die in direkter Wirkverbindung zu den Zahnrädern der Eingangswelle stehen und eine Vorwärtsgangstufe bilden. Somit sind im Gegensatz zum weitläufig verbreiteten Stand der Technik zwei Abtriebswellen vorhanden, wobei sich alle Zahnräder zur Einrichtung einer In other words, the output shaft is free of gears that are in direct operative connection with the gears of the input shaft and form a forward gear. Thus, in contrast to the widely spread state of the art, two output shafts are present, with all gears to set up a
verbrennungsmotori sehen Vorwärtsgangstufe auf nur einer von beiden Abtriebswellen verteilen, wohingegen die andere Abtriebswelle mit dem Elektromotor wirkverbindbar ist. Verbrennungsmotori see forward gear on only one of two output shafts distribute, whereas the other output shaft is operatively connected to the electric motor.
Ferner ist es von Vorteil, wenn an der weiteren Abtriebswelle ein Losrad angeordnet ist, wobei das Losrad der weiteren Abtriebswelle und das zweite Losrad der Abtriebswelle in Zahneingriff stehen. Hierdurch ist es möglich Antriebsleistung zwischen den beiden Abtriebswellen zu übertragen. Furthermore, it is advantageous if a loose wheel is arranged on the further output shaft, wherein the idler gear of the further output shaft and the second idler gear of the output shaft are in meshing engagement. This makes it possible to transfer drive power between the two output shafts.
Femer ist es vorteilhaft, wenn das das Getriebe ein Getriebegehäuse aufweist, innerhalb dessen die Abtriebswelle und die weitere Abtriebswelle parallel zueinander angeordnet sind, wobei die Abtriebswelle innerhalb des Getriebegehäuses höher als die weitere Abtriebswelle angeordnet ist. Durch diese Maßnahme kann der Elektromotor über eine geringe Anzahl an Zwischenräder direkt oder indirekt an das erste Losrad angebunden werden, was Bauraum einspart. Furthermore, it is advantageous if the transmission has a transmission housing, within which the output shaft and the further output shaft are arranged parallel to each other, wherein the output shaft is disposed higher than the further output shaft within the transmission housing. By this measure, the electric motor can be connected via a small number of intermediate wheels directly or indirectly to the first idler gear, which saves installation space.
Ist das erste Losrad axial zwischen der Schaltkupplung und der Losradkupplung angeordnet, ergibt sich ein axial kompaktes Getriebe. Femer kann das Getriebe axial kurz gebaut werden, wenn das Parksperrenrad an der Abtriebswelle angeordnet ist. If the first idler gear is arranged axially between the clutch and the idler gear, an axially compact transmission results. Furthermore, the transmission can be made axially short when the parking lock gear is disposed on the output shaft.
Femer ist vorteilhaft, wenn das Getriebe ein Handscha! tgetri ebe oder ein Automatisiertes Manuelles Getriebe oder ein Doppelkupplungsgetriebe ist. Insbesondere von Vorteil ist es, wenn die Abtriebswelle ein Ritzel aufweist, das mit einem Zahnkranz des Differentials in Zahneingriff steht. Durch diese Maßnahme kann ein Front-Quer-Einbau des Getriebes im Kraftfahrzeug möglichst kompakt umgesetzt werden. Femer is advantageous if the transmission is a glove! tgetri ebe or an automated manual transmission or a dual-clutch transmission is. In particular, it is advantageous if the output shaft has a pinion, which with a ring gear of the differential in Tooth engagement is. By this measure, a front-transverse installation of the transmission in the motor vehicle can be implemented as compact as possible.
Ein vorteilhaftes Verfahren zum Einrichten eines Rückwärts fahrbetriebes sieht vor, dass das erste Losrad, das zweite Losrad und die Abtriebswelle mittels der Losradkupplung und mittels der Sehaltkupplung wirkverbunden sind, wobei das zweite Losrad, die An advantageous method for establishing a reverse driving operation provides that the first idler gear, the second idler gear and the output shaft are operatively connected by means of the idler clutch and by means of the Sehaltkupplung, wherein the second idler gear, the

Ferner ist es vorteilhaft, wenn das Getriebe mehrere Vorwärtsgangstufen verfügt, wobei das Getriebe zumindest eine elektromotorische Gangstufe verfügt, die mit einer elektromotorischen Antriebsleistung angetrieben wird, wobei das Getriebe dazu ausgebildet ist, die verbrennungsmotorischen Vorwärtsgangstufen und die Further, it is advantageous if the transmission has a plurality of forward gear ratios, wherein the transmission has at least one electromotive gear stage, which is driven by an electromotive drive power, wherein the transmission is adapted to the internal combustion engine forward gear ratios and
elektromotorische Gangstufen getrennt oder in Kombination einzurichten, wobei die Abtriebswelle bei Einrichten einer jeden verbrennungsmotorischen Vorwärtsgangstu fe und oder Einrichten einer jeden elektromotorischen Gangstufe ausschließlich mit einer elektromotorischen Antriebsleistung angetrieben wird und/oder dass die weitere electromotive gear stages to be set up separately or in combination, wherein the output shaft is driven in setting up each internal combustion engine forward gear Stu and or setting up each electromotive gear stage exclusively with an electromotive drive power and / or that the other

Mit diesem bevorzugtem Verfahren wird erreicht, dass die Antriebsleistung des With this preferred method is achieved that the drive power of
Verbrennungsmotors und die Antriebsleistung des Elektromotors in einem Hybridbetrieb erst an dem Zahnkranz des Differentials zusammentre ffen und sich dort addieren. Das hat zur Folge, dass jene Zahnräder, die im Leistungsfluss eines verbrennungsmotorischen Vorwärtsgangs liegen, keiner zusätzlichen Antriebsleistung, nämlich die des Combustion engine and the drive power of the electric motor in a hybrid operation only at the ring gear of the differential zusammenmit bere and add up there. This has the consequence that those gears that are in the power flow of a combustion engine forward gear, no additional drive power, namely that of the
Elektromotors, ausgesetzt sind. Es entfällt somit eine Anpassung der Zahnräder in Form von breiter ausgeführten Zahnrädern, die dazu in der Lage wären, größere Drehmomente zu übertragen. In anderen Worten ausgedrückt ist die Abtriebswelle frei von Zahnrädern, die in direkter Wirkverbindung zu den Zahnrädern der Eingangswelle stehen und eine Vorwärtsgangstufe bilden. Somit sind im Gegensatz zum weitläufig verbreiteten Stand der Technik zwei Abtriebswellen vorhanden, wobei sich alle Zahnräder zur Einrichtung einer Electric motor, are exposed. It thus eliminates an adaptation of the gears in the form of wider gear wheels, which would be able to transmit larger torques. In other words, the output shaft is free of gears that are in direct operative connection with the gears of the input shaft and form a forward gear. Thus, in contrast to the widely spread state of the art, two output shafts are present, with all gears to set up a
