Abstract

The transmission (1) has a component transmission unit (2) whose input shaft (4) is coupled to an electrodynamic starting element (5) that is connected with an output shaft of an internal combustion engine. A lock-up clutch (11) is provided for detachable connection of an electrical machine (10) with the engine. An input shaft (6) of another component transmission unit (3) is detachably connected to the output shaft of the engine by a starting clutch (7). Another electrical machine (8) is arranged behind the starting clutch in a power flow direction during a traction mode.

Description

Die vorliegende Erfindung bezieht sich auf ein Lastschaltgetriebe in Doppelkupplungsbauweise gemäß dem Oberbegriff des Patentanspruchs 1.The The present invention relates to a power shift transmission in Double clutch construction according to the preamble of claim 1

Aus dem Stand der Technik sind Lastschaltgetriebe in Doppelkupplungsbauweise bekannt, die keinen hydrodynamischen Wandler sondern zwei trockene oder nasse Anfahrkupplungen aufweisen, welche maximal das aktuelle Verbrennungsmotormoment an den Getriebeeingang übertragen können. Um die erforderliche Anfahrleistung wie mit einem Wandler-Lastschaltgetriebe zu erzielen, wird nach bei derartigen Getrieben dem Stand der Technik die Getriebespreizung erhöht, indem eine zusätzliche Anfahrgangstufe eingebaut wird, was in nachteiliger Weise zu einer Getriebeverlängerung und somit zu einem erhöhten Varianten- und Logistikaufwand führt.Out The prior art are powershift transmission in dual clutch design known that no hydrodynamic converter but two dry or wet starting clutches, which maximum the current Internal combustion engine torque transmitted to the transmission input can. To the required starting power as with a converter powershift transmission to achieve in such transmissions according to the prior art the transmission spread increased by an additional starting gear is installed, which disadvantageously to a transmission extension and thus leads to increased variant and logistics effort.

Um ein derartiges Doppelkupplungsgetriebe zu einem Hybridantrieb auszubauen, wird zusätzlich noch eine elektrische Maschine in den Antriebsstrang, vorzugsweise am Getriebeeingang, eingebaut. Daraus ergibt sich je nach erzieltem Integrationsgrad von elektrischer Maschine und Kupplungen eine mehr oder weniger große Getriebeverlängerung, die sich vor allem bei Pkw-Anwendungen bei Standard-Hinterachsantrieben durch Bauraum- und Kollisionsprobleme mit angrenzenden Tunnelteilen in nachteilig auswirkt. Bei Front-Quer-Anordnungen kann die Getriebeverlängerung nicht realisiert werden.Around to develop such a dual-clutch transmission into a hybrid drive, In addition, an electric machine in the drive train, preferably at the transmission input, installed. It always results after achieved degree of integration of electric machine and clutches one more or less large transmission extension, especially in car applications with standard rear axle drives due to installation space and collision problems with adjacent tunnel parts adversely affects. In front-transverse arrangements, the transmission extension not realized.

Aus der noch nicht veröffentlichten DE 10 2007 022 774 der Anmelderin, die vollinhaltlich Gegenstand dieser Beschreibung sein soll geht ein Lastschaltgetriebe in Doppelkupplungsbauweise umfassend ein integriertes Hybridmodul hervor, welches zwei Teilgetriebe umfasst, wobei die Eingangswelle des ersten Teilgetriebes mit einem elektrodynamischen Anfahrelement (EDA) gekoppelt ist und die Eingangswelle des zweiten Teilgetriebes mit einer Reibkupplung verbunden ist, welche keine Anfahrfunktion übernimmt.
