Description
Die vorliegende Erfindung betrifft ein Mehrfachkupplungsgetriebe gemäß dem Oberbegriff des Patentanspruchs 1.The present invention relates to a multiple clutch transmission according to the preamble of the claim 1.
Mehrfachkupplungsgetriebe in der Form von Doppelkupplungsgetrieben sind aus der Fahrzeugtechnik bekannt. Üblicherweise umfassen derartige Getriebe im wesentlichen zwei Teilgetriebe mit verschiedenen Zahnradpaaren, eine Doppelkupplung mit zwei Reibungskupplungen, eine Antriebswelle und eine Abtriebswelle sowie je nach Gangzahl formschlüssige, unsynchronisierte Schaltkupplungen. Mit einem Doppelkupplungsgetriebe können die Gänge lastfrei und ohne Zugkraftunterbrechung sowie ohne Verspannung der schaltbaren Gänge geschaltet werden, da sich der nächste zu schaltende Gang in dem nicht gekoppelten Teilgetriebe bereits eingelegt ist. Zum Schalten wird die eine Reibungskupplung geöffnet und die zweite entsprechend geschlossen.Multiple clutch transmission in the Form of double clutch transmissions are known from vehicle technology. Usually include such transmissions essentially two sub-transmissions different gear pairs, a double clutch with two friction clutches, an input shaft and an output shaft and depending on the number of gears positive, unsynchronized clutches. With a double clutch transmission can the gears free of load and without interruption of tractive power and without tensioning the switchable Gears switched be since the next Gear to be shifted already in the uncoupled sub-transmission is inserted. To switch, a friction clutch is opened and the second closed accordingly.
