Description
Anordnung eines Gruppengetriebes im Gesamtgetriebegehäuse Arrangement of a group transmission in the overall transmission housing
Die Erfindung betrifft eine Anordnung eines Gruppengetriebes in einem Gesamtgetriebegehäuse nach dem Oberbegriff von Anspruch 1.The invention relates to an arrangement of a group transmission in an overall transmission housing according to the preamble of claim 1.
Bei einem in großen Stückzahlen gefertigten 0 vielgängigen Wechselgetriebe ist es bekannt, den Planetensatz einer. Bereichsgruppe im Hauptgehäuse und die Doppelschaltkupplung in einem weiteren zweiten Gehäuseabschnitt anzuordnen. Der Planetensatz der Bereichsgruppe ist dabei vom Hauptgetriebe durch eine ~ Trennwand abgeschieden, in der auch die Wellen und dieIn a multi-speed change gearbox manufactured in large quantities, it is known to use the planetary gear set. Range group to arrange in the main housing and the double clutch in a further second housing section. The planetary gear set of the range group is separated from the main gearbox by a ~ partition in which the waves and the
Schaltstangen des Hauptgetriebes gelagert sind. Die Flansche des Hauptgehäuses und des weiteren zweiten Gehäuses sind weit in den Innenraum des Gesamtgetriebegehäuses hineingezogen, weil Getriebeelemente der Bereichsgruppe am 0 Getriebegehäuse festgelegt werden müssen. Darüber hinaus ragen von der Trennwand des Hauptgehäuses her Stege und Rippen in den Bauraum des Gruppengetriebes bis in die Ebene der Trennfläche zwischen Haupt- und dem zweiten Gehäuse hinein. Dieses zweite Gehäuse hat gleichfalls in den Bauraum 5 hineinragende Stege und Rippen, die wabenartig angeordnet sind und den Bauraum zur Unterbringung der vielen Getriebeelemente im Bereich der Schaltkupplung eines Gruppengetriebes beeinträchtigen. Zur Abstützung, z. B. eines Kupplungskörpers der Doppelschaltkupplung, sind auchShift rods of the main transmission are stored. The flanges of the main housing and the further second housing are drawn far into the interior of the overall gear housing because gear elements of the range group have to be fixed on the gear housing. In addition, webs and ribs protrude from the partition of the main housing into the installation space of the group transmission up to the level of the partition between the main and the second housing. This second housing likewise has webs and ribs projecting into the installation space 5, which are arranged like a honeycomb and impair the installation space for accommodating the many transmission elements in the area of the clutch of a group transmission. For support, e.g. B. a clutch body of the double clutch are also
30 rundum in den Bauraum hineinragende Stege und Rippen notwendig, weil auch der Kupplungskörper rund ausgebildet ist. Eine solche Einrichtung hat sich zwar über viele Jahre bewährt, die vielen Hinterschneidungen der Flansche, Stege und Rippen beeinträchtigen jedoch den Bauraum erheblich und30 ridges and ribs projecting all around into the installation space are necessary because the coupling body is also round. Such a device has proven itself over many years, but the many undercuts of the flanges, webs and ribs significantly affect the installation space and
-~ lassen auch keine modernen Fertigungsverfahren für die Gehäuseherstellung zu. Es ist deshalb Aufgabe der Erfindung, die Anordnung eines Gruppengetriebes im Gesamtgetriebegehäuse nach dem Oberbegriff von Anspruch 1 zu verbessern. Insbesondere sollen alle Hinterschneidungen in den jeweiligen Gehäusen wegfallen, damit die Fertigung derselben im- ~ also do not allow modern manufacturing processes for housing manufacture. It is therefore an object of the invention to improve the arrangement of a group transmission in the overall transmission housing according to the preamble of claim 1. In particular, all undercuts in the respective housings should be omitted so that the same can be manufactured in
Druckgußverfahren möglich wird und die Abstützung eines Getriebeelementes am Gehäuse soll in bezug auf Dauerfestigkeit gewährleistet sein.Die casting is possible and the support of a gear element on the housing should be guaranteed with respect to fatigue strength.
Diese Aufgabe wird mit den kennzeichnenden Merkmalen von Anspruch 1 erfüllt. Mit der Anordnung der Zwischenplatte werden nicht nur alle Hinterschneidungen an den Flanschen der Getriebegehäuse vermieden, so daß sich zur Öffnung der Gehäuse hin glatte Innenwände ergeben, sondern es ist auch einfach, an dieser Zwischenplatte ein Getriebeelement, das am Getriebegehäuse abgestützt werden soll, anzubringen. Wird z. B. ein Kupplungskörper direkt an der Zwischenplatte durch Schweißen fest angebracht, ergibt sich eine sehr einfache Aufnahme des Drehmoments am Gehäuse. Bereits eine sehr dünne Zwischenplatte kann sehr hohe Momente aufnehmen und infolge der großen eingespannten Flächen an den Flanschen der Gehäuse günstig auf diese übertragen. Es ist auch denkbar, zur weiteren Vereinfachung z. B. einen Kupplungskörper und eine Zwischenplatte einteilig zu gestalten, wobei alle modernen Herstellverfahren, wie z. B. Feinschmieden usw. , zur Anwendung kommen können. Die Zwischenplatte kann auch nur ringartig gestaltet werden mit auf einem Lochkreis angebrachten Löchern zur Aufnahme von Noppen. Damit ist es möglich, bereits bestehende Noppenscheiben, an denen z. B. ein Kupplungskörper angeordnet ist, in die Zwischenplatte einzuhängen, wenn geeignete Abstützungen am Hauptgehäuse vorgesehen sind. Die Erfindung ist nicht auf die Merkmalskombination der Ansprüche beschränkt. Für den Fachmann ergeben sich weitere sinnvolle Kombinationsmöglichkeiten von Ansprüchen und einzelnen Anspruchsmerkmalen aus der Aufgabenstellung.This object is achieved with the characterizing features of claim 1. With the arrangement of the intermediate plate not only all undercuts on the flanges of the gearbox housing are avoided, so that there are smooth inner walls towards the opening of the housing, but it is also easy to attach a gear element to this intermediate plate which is to be supported on the gearbox housing. Is z. B. a coupling body directly attached to the intermediate plate by welding, there is a very simple absorption of the torque on the housing. Even a very thin intermediate plate can absorb very high moments and, due to the large clamped areas on the flanges of the housings, can be cheaply transferred to them. It is also conceivable, for further simplification, for. B. to design a coupling body and an intermediate plate in one piece, with all modern manufacturing processes such. B. fine forging, etc., can be used. The intermediate plate can also be designed in a ring-like manner with holes on a bolt circle for receiving knobs. This makes it possible to use existing pimples on which, for. B. a coupling body is arranged to hang in the intermediate plate if suitable supports are provided on the main housing. The invention is not limited to the combination of features of the claims. For the specialist, there are further useful combinations of claims and individual claim characteristics from the task.

In Fig. 1 ist das Gruppengetriebe 1 (Bereichsgruppe) mit dem Planetensatz 11 im Hauptgehäuse 2 und die Doppelschaltkupplung 15 in einem weiteren zweiten Gehäuseabschnitt 3 angeordnet. Der Planetensatz 11 des Gruppengetriebes 1 ist dabei über eine Trennwand 24, in der sowohl die Wellen 26 wie auch die Schaltstangen 27 des Hauptgetriebes gelagert sind, getrennt. Die Flansche 21, 31 des Hauptgehäuses 2 und des zweiten Gehäuses 3 sind weit in den Innenraum 28, 38 des Gesamtgetriebegehäuses 2, 3 hineingezogen, weil Getriebeelemente 16 der Bereichsgruppe 1 am Getriebegehäuse 2, 3 festgelegt werden müssen. Darüber hinaus ragen von der Trennwand 24 des Hauptgehäuses 2 her in Fig. 1 nicht dargestellte Stege und Rippen in den Bauraum des Gruppengetriebes hinein. Das zweite Gehäuse 3 hat gleichfalls in den Bauraum hineinragende Stege und Rippen, die wabenartig angeordnet sind und den Bauraum zur Unterbringung der vielen Getriebeelemente im Bereich der Schaltkupplung 15 des Gruppengetriebes 1 beeinträchtigen.Oil tube and the intermediate plate. In Fig. 1, the group transmission 1 (range group) with the planetary gear set 11 in the main housing 2 and the double clutch 15 is arranged in a further second housing section 3. The planetary gear set 11 of the group transmission 1 is separated via a partition 24 in which both the shafts 26 and the shift rods 27 of the main transmission are mounted. The flanges 21, 31 of the main housing 2 and the second housing 3 are drawn far into the interior 28, 38 of the overall gear housing 2, 3 because gear elements 16 of the range group 1 have to be fixed on the gear housing 2, 3. In addition, webs and ribs (not shown in FIG. 1) protrude from the partition wall 24 of the main housing 2 into the installation space of the group transmission. The second housing 3 also has webs and ribs projecting into the installation space, which are arranged like a honeycomb and impair the installation space for accommodating the many transmission elements in the area of the clutch 15 of the group transmission 1.
in Fig. 2 ist das Gruppengetriebe 1, wie schon nachin Fig. 2 is the group transmission 1, as already after
Fig. 1 erläutert, angeordnet. Gleiche Teile haben auch die gleiche Bezeichnung. Das Hauptgehäuse 20 sowie das zweite Gehäuse 30 haben jedoch Flansche 210, 310, die ausschlie߬ lich nach außen gerichtet sind, so daß sich im Innenraum glatte Wände und keine Hinterschneidungen ergeben. Zwischen den beiden Gehäusen 20, 30 ist über die gesamte Fläche der Flansche 210, 310 eine Zwischenplatte 4 eingespannt und an dieser ist radial innen ein Kupplungskörper 16 fest, z. B. durch Schweißen, angeordnet. Die Abstützung des Kupplungskörpers 16 wirkt dabei wie folgt: über eine nicht dargestellte Schaltgabel, die in die Aussparung 170 der Schiebemuffe 17 eingreift, wird diese über einen ebenfalls nicht dargestellten Betätigungskolben in Richtung auf den Kupplungskörper 16 zubewegt. Damit wird das Hohlrad 12 des Umlaufrädergetriebes 11 über denFig. 1 explains arranged. The same parts have the same name. The main housing 20 and the second housing 30, however, have flanges 210, 310 which are directed exclusively towards the outside, so that there are smooth walls in the interior and no undercuts. Between the two housings 20, 30, an intermediate plate 4 is clamped over the entire surface of the flanges 210, 310 and on this a coupling body 16 is fixed radially on the inside, for. B. arranged by welding. The support of the coupling body 16 acts as follows: Via a shift fork, not shown, which engages in the recess 170 of the sliding sleeve 17, the latter is moved towards the clutch body 16 via an actuating piston, also not shown. So that the ring gear 12 of the epicyclic gear 11 on the
Synchronkörper 18 und den Kupplungskörper 16 sowie die Zwischenplatte 4 am Gehäuse 20, 30 abgestützt.Synchronizer body 18 and the clutch body 16 and the intermediate plate 4 supported on the housing 20, 30.
In dem Teilschnitt nach Fig. 3 ist die Zwischenplatte 4 zwis'chen dem Hauptgehäuse 20 und dem zweiten Gehäuse 30 eingespannt. Der Kupplungskörper 16 ist mit der Zwischenplatte 4, z. B. durch Schweißen, fest verbunden und die Zwischenplatte selbst hat noch zur Versteifung eine Profilierung 41. Mit 17 ist die Schiebemuffe der Schaltkupplung 15 bezeichnet und in die Aussparung 170 greift die nicht dargestellte Schaltgabel ein und bewirkt nach der Synchronisierung das formschlüssige Kuppeln der Verzahnungen 171 und 161 von der Schiebemuffe 17 und dem Kupplungskörper 16.In the partial section according to FIG. 3, the intermediate plate 4 is clamped between the main housing 20 and the second housing 30. The coupling body 16 is with the intermediate plate 4, for. B. by welding, firmly connected and the intermediate plate itself still has a profile 41 for stiffening. With 17, the sliding sleeve of the clutch 15 is designated and engages in the recess 170, the shift fork, not shown, and causes the positive coupling of the teeth 171 after synchronization and 161 from the sliding sleeve 17 and the coupling body 16.
Die Fig. 4 ist ähnlich wie die Fig. 3, nur die Zwischenplatte 400 ist mit dem Kupplungskörper 160 einteilig ausgeführt.FIG. 4 is similar to FIG. 3, only the intermediate plate 400 is made in one piece with the coupling body 160.
Die Fig. 5 zeigt ein weiteres Ausführungsbeispiel, wobei der Kupplungskörper 16 in bekannter Weise mit einer Noppenscheibe 5 fest, z. B. durch Schweißen, verbunden ist. Die Noppen bzw. Durchzüge 51 greifen dabei in Löcher 43 der Zwischenplatte ein und werden von selten des Hauptgehäuses 20 über Stege 25, die an der Trennwand 24 angeordnet sind, gehalten. Diese Ausgestaltung ist dann von Vorteil, wenn die Schaltkupplung 15 in der bisher bekannten Weise in Verbindung mit einem Gruppengetriebe 1 in neue Gehäuse 20, 30 eingebaut werden soll. Eine Zwischenplatte in dieser Ausführungsform ist aus Fig. 6 zu ersehen. Die Zwischenplatte 40 hat den vollen Querschnitt eines Flansches 210, 310 von zumindest einem Gehäuse - Hauptgehäuse 20 oder zweites Gehäuse 30. Die Schrauben, die die beiden Getriebegehäuse 20 und 30 zusammen spannen, werden durch die Löcher 45 hindurchgeführt. Auf dem Teilkreis 42 sind die Löcher 43 zur Aufnahme der Noppen (Durchzüge 51) der Noppenscheibe 5 angeordnet. Die Zwischenplatten 4, 40 sind vorrangig dünnwandige Stahlplatten mit einer hohen Festigkeit und zurFig. 5 shows a further embodiment, the coupling body 16 in a known manner with a knob 5 fixed, for. B. is connected by welding. The knobs or passages 51 engage in holes 43 of the intermediate plate and are rarely held by the main housing 20 via webs 25 which are arranged on the partition 24. This embodiment is advantageous if the clutch 15 is to be installed in new housings 20, 30 in the previously known manner in connection with a group transmission 1. An intermediate plate in this embodiment can be seen in FIG. 6. The intermediate plate 40 has the full cross section of a flange 210, 310 of at least one housing main housing 20 or second housing 30. The screws that clamp the two gear housings 20 and 30 together are passed through the holes 45. The holes 43 for receiving the knobs (passages 51) of the knob disk 5 are arranged on the pitch circle 42. The intermediate plates 4, 40 are primarily thin-walled steel plates with high strength and
Gewichtsoptimierung sind in der Zwischenplatte 40 noch Durchbrüche 44 so angeordnet, daß eineWeight optimization are arranged in the intermediate plate 40 openings 44 so that a
Festigkeitsbeeinträchtigung zwischen der Einspannfläche 46 und der Befestigung des Kupplungskörpers 16 direkt bzw. der Noppenscheibe 5, an der ja der Kupplungskörper z. B. angeschweißt ist, nicht erfolgt. Neben der Befestigung von Getriebeelementen, z. B. dem Kupplungskörper 16 an der Zwischenplatte 4, 40 ist es auch möglich, Rohre 35 der Zentralschmierung an der Zwischenplatte in einfacher Weise zu lagern (Fig. 7) . Damit kann Schmiermittel günstig und ohne komplizierte Kanäle in einem der Gehäuseteile einfach in den Deckel 34 gefördert werden. Impairment of strength between the clamping surface 46 and the attachment of the coupling body 16 directly or the knob disk 5, on which the coupling body z. B. is welded, not done. In addition to the attachment of gear elements such. B. the coupling body 16 on the intermediate plate 4, 40, it is also possible to store tubes 35 of the central lubrication on the intermediate plate in a simple manner (Fig. 7). Lubricants can thus be easily conveyed into the cover 34 without complicated channels in one of the housing parts.
