Aufgabe der Erfindung ist es, ein möglichst kleines Doppelkupplungsgetriebe für frontgetriebene Fahrzeuge zu schaffen.task The invention is to have the smallest possible dual-clutch transmission to create front-wheel drive vehicles.
Diese Aufgabe wird erfindungsgemäß mit den Merkmalen von Patentanspruch 1 gelöst.These Task is according to the invention with the features of claim 1 solved.
Ein Vorteil der Erfindung ist die Nutzung mehrer Zahnräder der Vorwärtsgänge für den Rückwärtsgang. Dabei wird auf ein sonst übliches Zwischenrad zur Drehrichtungsumkehr verzichtet.One Advantage of the invention is the use of multiple gears the forward gears for reverse. It is on an otherwise common intermediate wheel to reverse the direction of rotation waived.
Der Leistungsfluss des Rückwärtsganges fließt von einer Hauptwelle über Zahnräder beiden Vorgelegewellen. Da sich der Durchmesser der beteiligten Zahnräder pro Welle unterscheiden kann, ermöglicht dies einen sehr großen Spielraum bei der Bauraumausnutzung.Of the Power flow of the reverse gear flows from a main shaft via gears both countershafts. Since the diameter of the involved gears per shaft this can make a very big difference Scope in the space utilization.
Die mit der hohen Anzahl von Zahnradstufen bzw. Verzahnungseingriffen einhergehende Verschlechterung des Wirkungsgrades ist im Rückwärtsgang nur von untergeordneter Bedeutung, da die Fahrt im Rückwärtsgang üblicherweise einen geringen Gesamtfahrtstreckenanteil ausmacht.The with the high number of gear stages or gear meshes the concomitant deterioration of the efficiency is in reverse only of secondary importance, since the ride in reverse usually makes up a small total distance.
Insbesondere sind zwei unterschiedliche Zahnradsätze ermöglicht, die nach dem Baukaustensystem die alternative Produktion von Sechs-Gang-Getrieben und Sieben-Gang-Getrieben bei nur geringem baulichen Unterschied ermöglicht. D. h. es kann in vorteilhafter Weise eine große Anzahl von Gleichteilen Verwendung finden.Especially are two different gear sets possible, according to the kit system, the alternative production of six-speed gearboxes and seven-speed transmissions with little structural difference allows. Ie. It can advantageously be a big one Number of identical parts find use.
Das erfindungsgemäße Doppelkupplungsgetriebe kann in besonders vorteilhafter Weise progressiv oder zumindest näherungsweise progressiv abgestuft sein.The inventive dual-clutch transmission can in a particularly advantageous manner progressive or at least approximately be progressively graduated.
Die Erfindung ist nachfolgend anhand eines Ausführungsbeispiels näher erläutert.The The invention is based on an embodiment explained in more detail.
