Abstract

In a manually shifted transmission for a motor vehicle with double clutch a central shaft emerges from the one clutch disc, by means of which shaft the one group of transmission gears is driven, whilst from the other clutch disc a hollow shaft emerges, on which the other group of transmission gears is arranged. In order to be able to use both clutch discs for torque transmission when starting the motor vehicle and to prevent any overheating, the central shaft and the hollow shaft are rotationally fixable to one another by a clutch.

Description

Die Erfindung betrifft ein Gangschaltgetriebe für ein Kraftfahrzeug mit Doppelkupplung nach dem Oberbegriff des Anspruchs 1.The invention relates to a gear shift transmission for a motor vehicle Double clutch according to the preamble of claim 1.

Ein derartiges Gangschaltgetriebe ist in VDI-Berichte Nr. 466, 1983, Seiten 101-108 beschrieben. Eine Zentralwelle, mit der die eine Gruppe von Getriebegängen angetrieben wird, ist mit der einen Kupplungsscheibe einer Doppelkupplung verbunden. Eine zur Zentralwelle konzentrische, kürzere Hohlwelle steht mit der anderen Kupplungsscheibe in Verbindung und treibt eine zweite Gruppe von Getriebegängen an. Nach Betätigen einer Kupplungsscheibe steht die zugehörige Gruppe von Getriebegängen für den Antrieb zur Verfügung, so daß die Umschaltung von einem Getriebegang der einen Ganggruppe auf einen Getriebegang der anderen Ganggruppe ohne Zugkraftunterbrechung erfolgen kann. Um den Einbauraum der Doppelkupplung klein zu machen und ein gutes Ansprechverhalten zu erzielen, werden die Kupplungsscheiben mit möglichst geringer Masse ausgeführt. Da hierdurch aber auch das Wärmespeichervermögen einer Kupplungsscheibe gering wird, kann es beim Anfahren des Kraftfahrzeugs zu einer Überhitzung der Kupplungsscheibe kommen.Such a gearshift transmission is described in VDI Report No. 466, 1983, Pages 101-108. A central shaft with which one group is driven by transmission gears, is with a clutch disc connected to a double clutch. A concentric to the central shaft, shorter hollow shaft is connected to the other clutch disc and drives a second group of transmission gears. After pressing one The associated group of transmission gears stands for the clutch disc Drive available so that switching from one gear to the one gear group on a gear of the other gear group without Traction interruption can take place. Around the installation space of the double clutch to make it small and to achieve good responsiveness Clutch disks with the lowest possible mass. Because of this but also the heat storage capacity of a clutch disc is low, Overheating of the motor vehicle when it starts up Clutch disc come.

Die Aufgabe der Erfindung besteht darin, ein Gangschaltgetriebe für ein Kraftfahrzeug mit Doppelkupplung zu entwickeln, mit dem eine unzulässig hohe Erwärmung einer Kupplungsscheibe verhindert werden kann.The object of the invention is a gear shift transmission for a To develop a motor vehicle with a double clutch, with which an impermissible high heating of a clutch disc can be prevented.

Zur Lösung dieser Aufgabe dienen die kennzeichnenden Merkmale des An­ spruchs 1. Wenn die Zentralwelle und die Hohlwelle durch eine schaltbare Kupplung drehfest miteinander verbindbar sind, können beim Anfahren des Kraftfahrzeugs beide Kupplungsscheiben gemeinsam benutzt werden. Somit steht die doppelte Wärmekapazität zur Verfügung und die erforderliche Anpreßkraft der Kupplungsscheibe ist nur halb so groß, so daß eine Überhitzung vermieden wird. The characteristic features of the To serve to solve this task saying 1. If the central shaft and the hollow shaft by a switchable Coupling are rotatably connected to each other, can when starting the Motor vehicle both clutch disks are used together. Consequently double the heat capacity is available and the required Contact pressure of the clutch disc is only half as large, so that one Overheating is avoided.  

Um das Gangschaltgetriebe günstig herstellen und montieren zu können, ist nach Anspruch 2 das aus der einen Hohlwelle herausragende Ende der Zentral­ welle drehfest mit einer zweiten, zur ersten koaxialen Hohlwelle verbunden, auf der die eine Ganggruppe angeordnet ist. Beide Hohlwellen sind recht kurz, so daß ihre präzise Fertigung keine Schwierigkeiten bereitet und auch für die Lagerung der Hohlwellen im Getriebegehäuse optimale Be­ dingungen vorliegen. Die schaltbare Kupplung ist bei dieser Ausführung zwischen den beiden Hohlwellen angeordnet und dient zu ihrer drehfesten Verbindung.In order to be able to manufacture and assemble the gear shift transmission cheaply according to claim 2, the protruding from a hollow shaft end of the central shaft rotatably connected to a second, coaxial hollow shaft, on which the aisle group is arranged. Both hollow shafts are right in short, so that their precise manufacture presents no difficulties and also optimal for the storage of the hollow shafts in the gear housing conditions exist. The switchable clutch is in this version arranged between the two hollow shafts and serves for their rotationally fixed Connection.

Als schaltbare Kupplung wird bevorzugt eine Zahnkupplung mit Schiebemuffe verwendet, wie sie bei Synchronisierkupplungen üblich ist. Die Betätigung der Schiebemuffen erfolgt über eine zusätzliche Schaltstange. Wenn der Zahnkupplung ein weiterer Getriebegang zugeordnet ist, kann er mit der gleichen Schaltstange betätigt werden. Umgekehrt kann für ein Sechsgang- Getriebe, bei dem ohnedies zum Betätigen des sechsten Ganges eine vierte Schaltstange nötig ist, mit dieser Schaltstange auch zugleich die schalt­ bare Kupplung betätigt werden.A gear coupling with a sliding sleeve is preferred as the switchable coupling used, as is usual with synchronizing clutches. The actuation the sliding sleeves are made using an additional shift rod. If the Tooth clutch is assigned another gear, he can with the same shift rod can be operated. Conversely, for a six-speed Transmission, in which a fourth to operate the sixth gear anyway Shift rod is necessary, with this shift rod also the switch bare clutch can be operated.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird nachfolgend erläutert. Es zeigtAn embodiment of the invention is shown in the drawing and is explained below. It shows

Fig. 2 Längsschnitt durch das Gangschaltgetriebe. Fig. 2 longitudinal section through the gear shift transmission.

Ein Gehäuse 1 einer Doppelkupplung wird von einem nicht dargestellten Kraftfahrzeugmotor in Umdrehung gesetzt. An eine Mittenplatte 2 des Gehäuses 1 ist wahlweise eine Kupplungsscheibe 3 oder eine Kupplungsscheibe 4 hydraulisch andrückbar, so daß das Antriebsmoment entweder in eine mit der Kupplungsscheibe 3 verbundene Zentralwelle 5 oder in eine mit der Kupplungsscheibe 4 verbundene Hohlwelle 6 eingeleitet wird. Das aus der Hohlwelle 6 vorstehende Ende der Zentralwelle 5 ist in einer zweiten Hohlwelle 7 in einem Vielkeilprofil drehmomentübertragend gehalten. Auf der Hohlwelle 6 sind die Festräder der Getriebegänge G 2 und G 4, auf der Hohlwelle 7 die Festräder für die Getriebegänge G 1, G 5, G 3 sowie dem Rückwärtsgang R in dieser Reihenfolge eingefräst. Alle zu den Getriebe­ gängen gehörigen Losräder sind samt den zugehörigen Synchronisierkupplungen 8, 9, 10 auf einer zu den Hohlwellen 6, 7 parallelen Abtriebswelle 11 angeordnet, die stirnseitig ein Kegelrad 12 trägt, das mit einem Tellerrad 13 für den Achsantrieb in Eingriff steht.A housing 1 of a double clutch is set in rotation by a motor vehicle engine, not shown. A clutch plate 3 or a clutch plate 4 can optionally be pressed hydraulically onto a center plate 2 of the housing 1 , so that the drive torque is introduced either into a central shaft 5 connected to the clutch plate 3 or into a hollow shaft 6 connected to the clutch plate 4 . The protruding from the hollow shaft 6 end of the central shaft 5 is held in a torque-transmitting a splined profile in a second hollow shaft. 7 On the hollow shaft 6 the fixed gears of the gears G 2 and G 4 , on the hollow shaft 7 the fixed gears for the gears G 1 , G 5 , G 3 and the reverse gear R are milled in this order. All gears belonging to the gears are arranged together with the associated synchronizing clutches 8, 9, 10 on an output shaft 11 parallel to the hollow shafts 6, 7 , which carries a bevel gear 12 on the end face, which meshes with a ring gear 13 for the final drive.

Das Getriebegehäuse 14, in dem das Gangschaltgetriebe untergebracht ist, ist aus einem Achsgehäuse 15, einem Zwischengehäuse 16, einer Lagerplatte 17, einem Kupplungsgehäuse 18 und einer Gehäuseglocke 19 zusammengesetzt, wobei alle Gehäuseteile in dieser Reihenfolge hintereinander angeordnet und miteinander verschraubt sind. In dem Kupplungsgehäuse 18 ist eine schalt­ bare Zahnkupplung angeordnet, mit der die beiden Hohlwellen 6 und 7 drehstarr miteinander verbindbar sind. Die nach Art einer handelsüblichen Synchronisierkupplung aufgebaute Zahnkupplung besteht aus einem, auf der einen Hohlwelle 6 festen Zahnrad 21, einem auf der zweiten Hohlwelle 7 befestigten Zahnrad 22 sowie einer zum Kuppeln in beide Zahnräder 21, 22 einrückbaren, verzahnten Schiebemuffe 23. Die Zahnkupplung 20 liegt zwischen einem in der Lagerplatte 17 angeordneten Kegelrollenlager 24 der einen Hohlwelle 6 und einem, in dem Kupplungsgehäuse 18 angebrachten Kegelrollenlager 25 für die andere Hohlwelle 7. Am anderen Ende ist die Hohlwelle 6 in dem Zwischengehäuse 16, die Hohlwelle 7 in der Bodenplatte der Gehäuseglocke 19 gelagert. So entsteht ein kompakter Lagerverbund für die beiden relativ kurzen Hohlwellen 6 und 7 sowie die zwischen angeordnete Zahnkupplung 20. Das in der Hohlwelle 7 befestigte Ende der Zentralwelle 5 ist etwas biegsam und kann sich der Lagertoleranz dieser Hohlwelle 7 an­ passen, da die Zentralwelle 5 frei mit reichlich Spiel durch die Hohlwelle 6 hindurchgeführt ist.The gear housing 14 , in which the gear shift transmission is housed, is composed of an axle housing 15 , an intermediate housing 16 , a bearing plate 17 , a clutch housing 18 and a housing bell 19 , all housing parts being arranged one behind the other in this order and being screwed together. In the clutch housing 18 , a switchable tooth coupling is arranged, with which the two hollow shafts 6 and 7 can be connected in a rotationally rigid manner. The toothed clutch constructed in the manner of a commercially available synchronizing clutch consists of a gearwheel 21 fixed on the one hollow shaft 6 , a gearwheel 22 fastened on the second hollow shaft 7 and a toothed sliding sleeve 23 which can be inserted into both gearwheels 21, 22 . The toothed clutch 20 lies between a tapered roller bearing 24 of the one hollow shaft 6 arranged in the bearing plate 17 and a tapered roller bearing 25 for the other hollow shaft 7, which is attached in the clutch housing 18 . At the other end, the hollow shaft 6 is mounted in the intermediate housing 16 , the hollow shaft 7 in the base plate of the bell housing 19 . This creates a compact bearing assembly for the two relatively short hollow shafts 6 and 7 and the tooth coupling 20 arranged between them. The end of the central shaft 5 fastened in the hollow shaft 7 is somewhat flexible and can adapt to the bearing tolerance of this hollow shaft 7 , since the central shaft 5 is freely guided through the hollow shaft 6 with plenty of play.
