Description
Die Erfindung betrifft ein mit einem Rückwärtsgang versehenes Mehrgang-Zahnräderwechselgetriebe für landwirtschaftliche Zugmaschinen, dem ein Multiplikationsgetriebe vorgeschaltet ist.The invention relates to a multi-speed gear change transmission provided with a reverse gear for agricultural tractors, which is preceded by a multiplication gear is.
Bekannt sind Getriebe, bei denen das Multiplikationsgetriebeteil neben dem Richtungswechselteil angeordnet ist.Gearboxes are known in which the multiplication gear part is next to the direction changing part is arranged.
Demgegenüber ist beim Erfindungsgegenstand eines der Zahnräder des Multiplikationsgetriebes in das in das Umkehrrad des Rückwärtsganges eingreifende Vorgelegezahnrad des Zahnräderwechselgetriebes einschiebbar. Diese Maßnahme hat den Vorteil der Raumeinsparung, aber auch den Vorteil der Einsparung von -Bauteilen.In contrast, the subject matter of the invention is one of the gears of the Multiplication gear engaging in the reverse gear of the reverse gear Lays gear of the gear change transmission can be pushed in. This measure has the advantage of saving space, but also the advantage of saving components.
In der Zeichnung ist ein Ausführungsbeispiel dargestellt. Die Abb. i zeigt einen Längsschnitt durch ein Getriebe, während die Abb. 2 und 3 Querschnitte durch das Rückwärtsgangvorgelege veranschaulichen.An exemplary embodiment is shown in the drawing. Fig. i shows a longitudinal section through a transmission, while Figs. 2 and 3 cross sections illustrate by the reverse gear.
Die angetriebene Welle i ist durch eine Scheibenkupplung und eine Klauenkupplung mit der gleichachsig. gelagerten Vorgelegewelle 2 gekuppelt, die die zwei Zahnräder des Wendegetriebes trägt, zu dem noch das Wendezahnrad 3, die Zahnräder 4 und 5, der Keilring 6 und der Klauenkupplungsring 7 gehören. Die Teile 4, 5 und 6 sind auf der Vorgelegekeilwelle 8 unverschieblich, das Teil 7 auf dem Teil 6 jedoch verschieblich gelagert. Auf der Vorgelegekeilwelle 8 sitzt ferner das Zahnrad 9 des Multiplikationsgetriebes axial verschieblich, das Zahnrad Io des Vorgeleges für die Motorabhängigkeit der Zapfwelle II jedoch unverschieblich.The driven shaft i is through a disc clutch and a Claw coupling with the coaxial. bearing countershaft 2 coupled to the carries the two gears of the reversing gear, to which the reversing gear 3, the Gears 4 and 5, the wedge ring 6 and the dog clutch ring 7 belong. The parts 4, 5 and 6 are immovable on the countershaft 8, the part 7 on the Part 6, however, can be displaced. On the countershaft 8 is also seated the gear 9 of the multiplication gear is axially displaceable, the gear Io des Back gear for the engine dependency of the PTO shaft II, however, immovable.
Die Vorgelegewelle i2 trägt die Gruppen von Zahnrädern 13, 14, 15, von denen die Vorgelegezahnräder I5a, I5b dieselbe Größe haben. Mit dem Vorgelegezahnrad I5b steht das doppelt so breite Umkehrrad 16 des Rückwärtsganges ständig im Eingriff. Mit diesem Umkehrrad 16 und dem Vorgelegezahnrad I5a kann das auf der Hohlwelle 17 axial verschieblich gelagerte Zahnrad 18 zusammenwirken, dessen drei Schaltstellungen mit R, S und T gekennzeichnet sind. Auch die Zahnradgruppe I9 ist auf der Hohlwelle 17 axial verschieblich gelagert, während das Zahnrad 2o fest auf dem Ende i Ia der Zapfwelle II sitzt. Mit Hilfe des Klauenkupplungsringes 21, der verschiebbar auf dem Keilring 22 sitzt, kann abwechselnd die Zapfwelle i i mit dem Zahnrad 2o bzw. mit der Hohlwelle 17 verkuppelt werden, so daß im einen Fall die Zapfwelle motorabhängig, im anderen Fall getriebeabhängig läuft.The countershaft i2 carries the groups of gears 13, 14, 15, of which the countershaft gears I5a, I5b have the same size. With the counter gear I5b, the reversing wheel 16 of the reverse gear, which is twice as wide, is constantly in engagement. This can be done on the hollow shaft with this reversing gear 16 and the countershaft gear I5a 17 interacting axially displaceably mounted gear 18, its three switching positions marked with R, S and T. Gear group I9 is also on the hollow shaft 17 axially displaceable, while the gear 2o firmly on the end of i Ia PTO II is seated. With the help of the claw coupling ring 21, which is slidable on seated on the wedge ring 22, the PTO shaft i i can alternate with the gear 2o resp. be coupled to the hollow shaft 17, so that in one case the PTO depends on the engine, in the other case runs depending on the gearbox.
Die Schnecke I7a treibt die Treibradwelle 23 der Fahrzeuglaufräder an. Die Teile 24, 25 und 27 sind Nadeln von Nadellagern. Das Gehäuseteil 27, der Deckel 28 und die Haube 29 sind Hauptteile des Getriebekastens. Die Haube 29 trägt den Anschlußknopf 29a für ein Anbaugerät, z. B. ein Halmfrucht-Schneidwerk, und den Anschlußkopf 29b für eine Radachse, wenn das Getriebe Teil eines Mehrachsfahrzeuges sein soll.The worm I7a drives the drive wheel shaft 23 of the vehicle wheels at. The parts 24, 25 and 27 are needles of needle roller bearings. The housing part 27, the Lid 28 and hood 29 are main parts of the gear box. The hood 29 carries the connection button 29a for an attachment, e.g. B. a strawberry cutter, and the connection head 29b for a wheel axle if the transmission is part of a multi-axle vehicle should be.
Das Getriebe hat sechs Vorwärtsgänge, einen Rückwärtsgang und sieben Zapfwellengänge; die Zahnräder 3 und 6 dienen dazu, das Fahrzeug auch in der anderen Fahrtrichtung mit gleicher Wirkung betreiben zu können.The transmission has six forward gears, one reverse gear and seven PTO shafts; the gears 3 and 6 serve to keep the vehicle in the other To be able to operate the direction of travel with the same effect.
In der Stellung R (Abb. 3) sind die Zahnräder 15b, 16, 18 im Eingriff, während in der Stellung T (Abb.2) die Zahnräder I5a und 18 ineinander kämmen. Die Stellung S ist die Leerlaufstellung.In the position R (Fig. 3) the gears 15b, 16, 18 are in mesh, while in position T (Fig.2) the gears I5a and 18 mesh with one another. the Position S is the idle position.
