Description

Die Erfindung betrifft ein Handschaltgetriebe für einen Hybrid-Antriebsstrang mit einer Getriebeeingangswelle und einer Getriebeausgangswelle.The invention relates to a manual transmission for a hybrid drive train with a transmission input shaft and a transmission output shaft.

Es ist bekannt, Elektromotoren zur Hybridisierung des Antriebsstrangs in diesen zu integrieren. Dies ist sowohl bei Automatik-Getrieben wie Doppelkupplungsgetrieben oder Automatikgetrieben möglich als auch bei Handschaltgetrieben.It is known to integrate electric motors for hybridizing the drive train in these. This is possible both with automatic transmissions such as dual-clutch transmissions or automatic transmissions and with manual transmissions.

Bekannte Handschaltgetriebe sind insbesondere bei Front-Quer-Einbau zu optimieren, damit ein zusätzlicher Elektromotor Platz finden kann.Known manual transmissions are to be optimized especially in front-transverse installation, so that an additional electric motor can find space.

Ausgehend hiervon ist es Aufgabe der vorliegenden Erfindung, ein Handschaltgetriebe für einen Hybrid-Antriebsstrang anzugeben, dass in axialer Richtung kürzer baut.Based on this, it is an object of the present invention to provide a manual transmission for a hybrid powertrain that builds shorter in the axial direction.

Zur Lösung dieses Problems wird ein Handschaltgetriebe vorgeschlagen, dass wenigstens zwei Vorgelegewellen aufweist.To solve this problem, a manual transmission is proposed that has at least two countershafts.

Ein Handschaltgetriebe ist ein Getriebe, das als einfaches Getriebe in Vorgelegebauweise ausgelegt ist. Es ist damit weder ein Doppelkupplungsgetriebe, das zwei parallele Getriebe vereinigt, noch ein Automatgetriebe mit Planetenradsätzen.A manual transmission is a transmission that is designed as a simple transmission in countershaft design. It is thus neither a dual-clutch transmission that combines two parallel transmission, nor an automatic transmission with planetary gear sets.

Es umfasst aber zunächst alle Arten von Automatisierung. Beispielsweise ist es bekannt, ein Handschaltgetriebe mittels Getriebeaktuator und Kupplungsaktuator in ein automatisiertes Schaltgetriebe umzufunktionieren. Weiterhin kann die Kupplungsbetätigung „by wire“ erfolgen. Auch eine Getriebebetätigung „by wire“ ist möglich.But it initially includes all sorts of automation. For example, it is known to convert a manual transmission by means of a transmission actuator and clutch actuator in an automated manual transmission. Furthermore, the clutch operation can be done "by wire". Also a gearbox operation "by wire" is possible.

In einer bevorzugten Ausführungsform ist das Handschaltgetriebe über einen rein mechanischen oder hydromechanischen und damit aktuatorlosen Betätigungsstrang betätigbar.In a preferred embodiment, the manual transmission can be actuated by means of a purely mechanical or hydromechanical and therefore actuatorless actuating train.

Zur Einsparung axialen Bauraums ist vorgesehen, dass das Handschaltgetriebe zwei oder mehr Vorgelegewellen aufweist. Vorteilhafterweise kann das Handschaltgetriebe genau zwei Vorgelegewellen aufweisen. Es besitzt aber nur eine einzige Eingangswelle.To save axial space is provided that the manual transmission has two or more countershafts. Advantageously, the manual transmission can have exactly two countershafts. But it has only a single input shaft.

Zur Verkürzung der axialen Baulänge ist vorteilhafterweise vorgesehen, dass der Kraftfluss zumindest bei einem Vorwärtsgang über alle Vorgelegewellen verläuft. Bei zwei Vorgelegewellen läuft er also über beide Vorgelegewellen. Insbesondere kann der Kraftfluss bei allen Vorwärtsgängen außer bei einem Direktgang über alle Vorgelegewellen verlaufen. Die Ausnahme des Direktgangs ist nur dann gegeben, wenn dieser auch vorgesehen ist. Bei einem Direktgang verläuft der Kraftfluss über keine Vorgelegewelle sondern direkt von der Getriebeeingangswelle zur Getriebeausgangswelle. Teilt man den Kraftfluss auf, können die Zahnräder nämlich axial kürzer ausgebildet werden. Dadurch wird eine Verkürzung des Bauraums in axialer Richtung erreicht.To shorten the axial length is advantageously provided that the power flow runs at least at a forward gear on all countershafts. So with two countershafts it runs over both countershafts. In particular, the power flow can run on all forward gears except for a direct gear on all countershafts. The exception of the direct gear is only given if this is also provided. In a direct gear, the power flow does not run via a countershaft but directly from the transmission input shaft to the transmission output shaft. Dividing the power flow, the gears can namely be formed axially shorter. This achieves a shortening of the installation space in the axial direction.

Dementsprechend kann vorzugsweise die Verzahnungsbreite der Zahnräder auf den Vorlegewellen im Vergleich zur Verwendung einer einzigen Vorgelegewelle reduziert sein. Mit anderen Worten sind die Verzahnungsbreiten der Zahnräder auf den Vorgelegewellen so ausgestaltet, dass ein Zahnrad alleine nicht das gesamte Drehmoment übertragen kann aber die Summe aller Zahnräder, die für einen bestimmten Gang Drehmoment übertragen, dies ermöglicht.Accordingly, preferably, the gearing width of the gears on the countershafts may be reduced as compared to using a single countershaft. In other words, the gear widths of the gears on the countershafts are such that a gear alone can not transmit all of the torque, but the sum of all the gears that transmit torque for a particular gear makes it possible.

Vorzugsweise kann die Getriebeeingangswelle mit den Vorgelegewellen über einen konstanten Radsatz verbunden sein. Dieser sorgt also bereits am Eingang des Getriebes für eine Aufspaltung des Kraftflusses.Preferably, the transmission input shaft may be connected to the countershafts via a constant gear set. This thus ensures already at the entrance of the transmission for a splitting of the power flow.

Als Getriebehauptwelle werden zusammenfassend die Getriebeeingangswelle oder die Getriebeausgangswelle bezeichnet. Vorteilhafterweise können sich alle Losräder auf einer Getriebehauptwelle, insbesondere der Getriebeausgangswelle, befinden. Die Getriebeausgangswelle ist die im Kraftfluss auf die Vorgelegewellen folgende Welle. Grundsätzlich kann die Getriebeausgangswelle noch über weitere Wellen abtreiben. Sie wird im Unterschied zur Getriebeeingangswelle aber als Getriebeausgangswelle bezeichnet.As the transmission main shaft, the transmission input shaft or the transmission output shaft are referred to collectively. Advantageously, all idler gears can be located on a transmission main shaft, in particular the transmission output shaft. The transmission output shaft is the shaft following the force flow on the countershafts. Basically, the transmission output shaft can still abort over other waves. It is called in contrast to the transmission input shaft but as a transmission output shaft.

Vorteilhafterweise kann das Handschaltgetriebe sechs Radsatzebenen für Vorwärtsgänge aufweisen. Weiterhin können die Radsatzebenen gerader und ungerader Vorwärtsgänge sich abwechseln. Die Anordnung der Gänge ist grundsätzlich beliebig.Advantageously, the manual transmission may have six Radsatzebenen for forward gears. Furthermore, the Radsatzebenen even and odd forward gears can alternate. The arrangement of the gears is basically arbitrary.

Vorzugsweise können die Radsatzebenen der geraden Gänge dem Verbrennungsmotor zugewandt sein. Dabei ist die spezielle Anordnung der Gänge bereits berücksichtigt, bei der vorgesehen ist, dass jeweils Paare aus geraden und ungeraden Gängen bestehen. Dann kann der jeweils gerade Gang dem Verbrennungsmotor zugewandt sein.Preferably, the Radsatzebenen the even gears may be facing the engine. In this case, the special arrangement of the aisles is already considered, in which it is provided that in each case pairs of even and odd gears exist. Then the respective straight gear may be facing the engine.

Vorzugsweise kann ein Gang als Direktgang ausgebildet sein. Hierbei kann es sich beispielsweise um den vierten Gang handeln.Preferably, a gear can be designed as a direct gear. This may be, for example, the fourth gear.

Vorzugsweise kann wenigstens ein Gangpaar mit einer Schubgabel betätigt werden. Besonders bevorzugt können alle Gänge mittels Schubgabeln betätigt werden.Preferably, at least one pair of gears can be operated with a push fork. Particularly preferred all gears can be operated by means of push forks.

Daneben betrifft die Erfindung einen Hybrid-Antriebsstrang mit einem Verbrennungsmotor, ein Handschaltgetriebe, einer Kupplungseinrichtung zwischen Verbrennungsmotor und Handschaltgetriebe und einem Elektromotor. Der Hybrid-Antriebsstrang zeichnet sich dadurch aus, dass das Handschaltgetriebe wie beschrieben ausgebildet ist. In addition, the invention relates to a hybrid powertrain with an internal combustion engine, a manual transmission, a coupling device between the internal combustion engine and manual transmission and an electric motor. The hybrid powertrain is characterized in that the manual transmission is designed as described.

Vorzugsweise kann der Elektromotor zwischen dem Verbrennungsmotor und der Kupplungseinrichtung angreifen. Es handelt sich also um einen sogenannten P2-Aufbau.Preferably, the electric motor between the internal combustion engine and the coupling device attack. It is therefore a so-called P2 structure.

Vorzugsweise kann zwischen dem Verbrennungsmotor und dem Elektromotor eine Trennkupplung angeordnet sein. Diese kann bei rein elektromotorischem Betrieb den Verbrennungsmotor abkoppeln.Preferably, a separating clutch can be arranged between the internal combustion engine and the electric motor. This can decouple the internal combustion engine in purely electric motor operation.

Der Elektromotor kann vorteilhafterweise als Niedervolt-Gleichspannungs-Elektromotor ausgebildet sein.The electric motor can be advantageously designed as a low-voltage DC electric motor.

Daneben betrifft die Erfindung ein Kraftfahrzeug mit einem Hybrid-Antriebsstrang. Das Kraftfahrzeug zeichnet sich dadurch aus, dass der Hybrid-Antriebsstrang wie beschrieben ausgebildet ist.In addition, the invention relates to a motor vehicle with a hybrid powertrain. The motor vehicle is characterized in that the hybrid drive train is designed as described.

Weitere Vorteile, Merkmale und Einzelheiten der Erfindung ergeben sich aus der folgenden Beschreibung von Ausführungsbeispielen und Figuren. Dabei zeigt:

  • 1 einen Antriebsstrang.
Further advantages, features and details of the invention will become apparent from the following description of exemplary embodiments and figures. Showing:
  • 1 a drive train.

1 zeigt einen Hybrid-Antriebsstrang 1 mit einem Verbrennungsmotor 2, einem Elektromotor 3, einem Handschaltgetriebe 4, einer Trennkupplung 5 und einer Anfahrkupplung 6. Zwischen dem Verbrennungsmotor 2 und der Trennkupplung 5 können sich noch Schwingungsreduzierungsvorrichtungen wie ein Zweimassenschwungrad oder Tilgereinrichtungen befinden. 1 shows a hybrid powertrain 1 with an internal combustion engine 2 an electric motor 3 , a manual transmission 4 , a separating clutch 5 and a starting clutch 6 , Between the combustion engine 2 and the disconnect clutch 5 may still vibration reduction devices such as a dual-mass flywheel or absorber devices are located.

Das Handschaltgetriebe 4 umfasst eine Getriebeeingangswelle 7, eine Getriebeausgangswelle 8 und zwei Vorgelegewellen 9 und 10. Die Getriebeeingangswelle 7 ist mit den Vorgelegewellen 9 und 10 in der konstanten Radsatzebene K über die Festräder 12 und 14 mit den Vorgelegewellen 9 und 10 verbunden. Die Festräder 14 sowie 16, 18, 20, 22 und 24 sind auf beide Vorgelegewellen 9 und 10 mit gleichen Bezugszeichen versehen, da sie jeweils identisch ausgebildet sind. Die Konstantradebene K dient der Aufteilung des Kraftflusses, hier in zwei Kraftflüsse, die jeweils gleiche Kräfte übertragen. Grundsätzlich kann die Verteilung auf die beiden Vorgelegewellen 9 und 10 auch anders erfolgen jedoch ist dann die Minimierung der Zahnräder in axialer Richtung nicht mehr optimal.The manual transmission 4 includes a transmission input shaft 7 , a transmission output shaft 8th and two countershafts 9 and 10 , The transmission input shaft 7 is with the countershafts 9 and 10 in the constant Radsatzebene K on the fixed wheels 12 and 14 with the countershafts 9 and 10 connected. The fixed wheels 14 such as 16 . 18 . 20 . 22 and 24 are on both countershafts 9 and 10 provided with the same reference numerals, since they are each formed identically. The Konstantradebene K serves to divide the power flow, here in two power flows, each transmitting the same forces. Basically, the distribution on the two countershafts 9 and 10 However, otherwise done minimizing the gears in the axial direction is no longer optimal.

Nach der Aufteilung des Kraftflusses auf die beiden Getriebeeingangswellen 9 und 10 wird über die Losräder 26, 28, 30, 32, 34 und 36 die Kraft auf der Getriebeausgangswelle 8 wieder vereinigt.After splitting the power flow to the two transmission input shafts 9 and 10 is about the loose wheels 26 . 28 . 30 . 32 . 34 and 36 the force on the transmission output shaft 8th reunited.

Dabei befinden sich alle Schaltvorrichtungen 38, 40, 42 und 44 auf der Getriebeausgangswelle 8. Durch Schaltung der Schaltvorrichtung 38 kann entweder der vierte Gang als der Direktgang oder der dritte Gang eingelegt werden.There are all switching devices 38 . 40 . 42 and 44 on the transmission output shaft 8th , By switching the switching device 38 either the fourth gear can be engaged as the direct gear or the third gear.

Die Schaltvorrichtung 40 dient zum Schalten der Gänge 5 und 6, die Schaltvorrichtung 42 zum Schalten der Gänge 1 und 2. Die entsprechenden Gänge sind über den Zahnradebenen jeweils eingezeichnet. Mit der Schaltvorrichtung 44 kann der Rückwärtsgang R eingelegt werden. Zur Richtungsumkehr befindet sich zwischen dem Losrad 36 und dem Zahnrad 46 noch ein Zwischenrad 48.The switching device 40 serves to shift the gears 5 and 6 , the switching device 42 for switching the gears 1 and 2 , The corresponding gears are shown above the gear levels. With the switching device 44 the reverse gear R can be engaged. To reverse direction is located between the idler gear 36 and the gear 46 another idler 48 ,

Das Handschaltgetriebe 4 hat dementsprechend sechs Radsatzebenen für Vorwärtsgänge. Die Radsatzebenen der Gerade und der ungeraden Vorwärtsgänge wechseln sich ab.The manual transmission 4 Accordingly, has six Radsatzebenen for forward gears. The Radsatzebenen the straight line and the odd forward gears alternate.
