Abstract
Description
Die vorliegende Erfindung betrifft ein Synchronisierungsverfahren für ein Mehrfachkupplungsgetriebe gemäß dem Oberbegriff des Patentanspruchs 1.The present invention relates to a synchronization process for a multiple clutch transmission according to the preamble of the claim 1.
Um in einem Zahnradwechselgetriebe von einem Gang in einen anderen zu schalten, ist es erforderlich, die beiden zu verbindenden Getriebeteile auf die gleiche oder auf eine annähernd gleiche Drehzahl zu bringen. Bei automatisierten Schaltgetrieben geschieht dies meistens durch Motorregelung und Zugkraftunterbrechung.To in a gear change shifting from one gear to another, it is necessary the two gear parts to be connected to the same or on an approximation bring the same speed. With automated gearboxes this usually happens through engine control and traction interruption.
Im wesentlichen besteht ein Doppelkupplungsgetriebe aus zwei Strängen bzw. Teilgetrieben mit verschiedenen Zahnradpaaren, zwei Lastschaltkupplungen die jeweils einem Teilgetriebe zugeordnet sind, einer Antriebswelle und einer Abtriebswelle sowie je nach Gangzahl aus formschlüssigen, unsynchronisierten Schaltkupplungen. Die Gänge sind hierbei abwechselnd in den zwei Teilgetrieben angeordnet, so dass es möglich ist, einen Gang im lastfreien Teilgetriebe vorzuwählen, während das Drehmoment vom anderen Teilgetriebe übertragen wird. Eine Gangschaltung wird realisiert, indem das zu übertragende Drehmoment von der einen Kupplung an die andere übergeben wird.There is essentially a dual clutch transmission from two strands or partial transmissions with different gear pairs, two powershift clutches which are each assigned to a partial transmission, a drive shaft and an output shaft and, depending on the number of gears, form-fitting, unsynchronized clutches. The gears are alternating arranged in the two sub-transmissions so that it is possible Preselect one gear in the no-load sub-transmission, while the torque from the other Transfer partial transmission becomes. A gear shift is realized by the one to be transmitted Torque is passed from one clutch to the other.
Zur Synchronisierung kann eine zweiphasige Synchronisierung verwendet werden. Mit dem Doppelkupplungsgetriebe können die Gänge lastfrei und ohne Zugkraftunterbrechung sowie ohne Verspannung der schaltbaren Gänge geschaltet werden.A two-phase synchronization can be used for synchronization be used. With the dual clutch transmission, the Gears free of load and without interruption of tractive power and without tensioning the switchable Gears switched become.
Bei Mehrfachkupplungsgetrieben bzw. Doppelkupplungsgetrieben werden Synchronisierungshilfen eingesetzt, welche die zu kuppelnden Getriebeelemente unter lastlosem Zustand synchronisieren. Der Einsatz von Synchronisierungshilfen ist jedoch mit erheblichem konstruktivem Aufwand und entsprechend hohen Herstellungskosten verbunden.With multiple clutch transmissions or Double clutch transmissions use synchronization aids, which the gear elements to be coupled under no load condition synchronize. However, the use of synchronization aids with considerable design effort and correspondingly high manufacturing costs connected.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Synchronisierungsverfahren für ein Mehrfachkupplungsgetriebe anzugeben, welches die erwähnten Nachteile des Standes der Technik vermeidet. Insbesondere soll der Synchronisierungsvorgang ohne zusätzlichen Hardwareaufwand durchführbar sein.The present invention lies based on the task of a synchronization method for a multiple clutch transmission indicate which of the mentioned Avoids disadvantages of the prior art. In particular, the Synchronization process can be carried out without additional hardware.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruches 1 gelöst. Weitere vorteilhafte Ausgestaltungen gehen aus den Unteransprüchen hervor.This object is achieved by the Features of claim 1 solved. Further advantageous configurations go from the dependent claims out.
Demnach wird vorgeschlagen, die nicht im Kraftfluss liegende Lastschaltkupplung einzusetzen, um die in diesem Strang bzw. Teilgetriebe liegenden zu kuppelnden Elemente zu synchronisieren. Hierbei wird erfindungsgemäß die betreffende Lastschaltkupplung derart zum Rutschen gebracht, daß die damit verbundene Welle die Drehzahl des mit ihr zu verbindenden Zahnrades annimmt.Accordingly, it is suggested that not power shift clutch located in the power flow to use the in elements to be coupled to this line or partial transmission to synchronize. Here, according to the invention, the power shift clutch in question brought to slip so that the associated shaft assumes the speed of the gear to be connected to it.
Die Erfindung wird im folgenden beispielhaft anhand der beigefügten Figur, die eine schematische Darstellung eines Doppelkupplungsgetriebes zeigt näher erläutert.The invention is illustrated below by way of example the attached Figure, which is a schematic representation of a dual clutch transmission shows closer explained.
In der Figur ist ein Doppelkupplungsgetriebe mit
einem Antriebsrad
Das erfindungsgemäße Synchronisierungsverfahren
wird wie folgt durchgeführt:
Bei geschlossener Lastschaltkupplung A und Klauenkupplung S1 wird
die Antriebsleistung über
die Zahnräder
Wenn in dieser Situation die Klauenkupplung S4
ebenfalls geschlossen ist, dann dreht sich die Welle
Wenn die Antriebsleistung über die
Welle
Das hier vorgestellte Verfahren kann erfindungsgemäß auch bei Mehrfachkupplungsgetrieben, die mehr als zwei Teilgetriebe umfassen, angewandt werden. Hierbei wird eine nicht im Kraftfluss liegende Lastschaltkupplung eingesetzt, um die in diesem Strang bzw. Teilgetriebe liegenden, für die nächste Schaltung benötigten, zu kuppelnden Elemente zu synchronisieren.The method presented here can according to the invention also at Multiple clutch transmissions, which comprise more than two partial transmissions, be applied. This is a power shift clutch that is not in the power flow used in order to control the for the next circuit required, synchronize to coupling elements.
Somit wird auf einfache Weise und ohne zusätzliche Bauelemente eine effektive Synchronisierung erzielt. Das erfindungsgemäße Verfahren kann analog auch zum Abbremsen eines mit einer Lastschaltkupplung verbundenen Teilgetriebes eingesetzt werden.Thus, and without additional Components achieved an effective synchronization. The method according to the invention can also be used to brake a power shift clutch connected sub-transmission can be used.
