Abstract

The cogwheel gearbox for tractors, and other towing vehicles, has a split gearing through a gear modification so that, on a slow input speed, the output speed is the same or faster. The split reduction is through a change in the number of teeth in at least one of the cogwheels (1,3). The mean reduction is selected to prevent a collision between the teeth at the forward drive shaft (2) and the reverse drive shaft (4).

Description

Die vorliegende Erfindung betrifft ein Zahnräderwechselgetriebe, umfassend ein Splitgetriebe für Traktoren und Schlepperfahrzeuge, gemäß dem Oberbegriff des Patentanspruchs 1.The The present invention relates to a change-speed gearbox comprising a split gearbox for tractors and tractor vehicles, according to the preamble of claim 1

Aus der DE 40 20 558 A1 der Anmelderin ist ein vielstufiges Zahnräderwechselgetriebe bekannt. Hierbei ist zwischen einer Eingangsgruppe und einer Hauptgruppe ein Zwischengetriebe angeordnet, wobei ein Doppelzahnrad einen zusätzlichen Schnellgang (Overdrive) bildet. Dieses Zahnräderwechselgetriebe ist für den Einsatz in land- und/oder bauwirtschaftlich genutzten Kraftfahrzeugen geeignet.From the DE 40 20 558 A1 The applicant is a multi-stage change gear known. Here, an intermediate gear is arranged between an input group and a main group, wherein a double gear forms an additional overdrive (overdrive). This gear change transmission is suitable for use in agricultural and / or construction motor vehicles used.

Heutzutage besteht die Notwendigkeit, die Eingangsdrehzahl derartiger Getriebe abzusenken, um die Getriebe an die neuen Motoren mit niedrigerer Drehzahl anzupassen.nowadays there is a need to know the input speed of such transmissions lower the gears to the new lower-speed engines adapt.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein aus der Anpassung eines bestehenden Getriebes resultierendes Zahnräderwechselgetriebe für Traktoren und Schlepperfahrzeuge anzugeben, welches bei geringerer Eingangsdrehzahl eine gleiche oder höhere Endgeschwindigkeit ermöglicht, ohne das bestehende Getriebe aufwendig modifizieren zu müssen.Of the present invention is based on the object, one of the adaptation of an existing transmission resulting gear shift transmission for tractors and to provide tractors, which at lower input speed an equal or higher Final speed allows without to have to modify the existing gear consuming.

Diese Aufgabe wird durch die Merkmale des Patentanspruchs 1 gelöst. Weitere erfindungsgemäße Ausgestaltungen und Vorteile gehen aus den Unteransprüchen hervor.These The object is solved by the features of claim 1. Further Embodiments of the invention and advantages are apparent from the dependent claims.

Demnach wird vorgeschlagen, durch Veränderung der Zähnezahl mindestens eines der Zahnräder die Splitterübersetzung ins Schnelle zu verändern.Therefore is proposed by change the number of teeth at least one of the gears the splinter translation to change quickly.

Hierbei wird die mittlere Übersetzung so gewählt, dass keine Kollision der Zähnezahl der Vorwärtswelle mit der Zähnezahl im Rückwärtsgang erfolgt.in this connection becomes the middle translation chosen so that no collision of the number of teeth the forward wave with the number of teeth in reverse he follows.

Im Rahmen einer weiteren Ausführungsform der Erfindung wird vorgeschlagen, für den Fall, dass eine Veränderung der Übersetzung ins Schnelle aufgrund von fehlendem „Fleisch" unter einem Zahnfuß nicht möglich ist, das Zahnrad durch Schweißen zu befestigen.in the Frame of a further embodiment of the Invention is proposed for the case of a change the translation in the fast due to lack of "meat" under a tooth root is not possible, the gear through welding to fix.

Im Rahmen einer weiteren Ausführungsform ist vorgesehen, die Übersetzung ins Schnelle unter Beibehaltung der mittleren Verzahnung zu erzeugen, wobei zwei Positionen, vorzugsweise H und M, in der Steuerung vertauscht und die Kennlinien der entsprechenden Kupplungen verändert werden.in the Frame of another embodiment provided the translation to produce in rapid while maintaining the average gearing, wherein two positions, preferably H and M, swapped in the controller and the characteristics of the respective clutches are changed.

Durch die erfindungsgemäße Konzeption wird die Anpassung eines bestehenden Getriebes an eine geringere Eingangsdrehzahl derart gewährleistet, dass bei geringerer Eingangsdrehzahl eine gleiche oder höhere Endgeschwindigkeit ermöglicht wird, ohne das bestehende Getriebe aufwendig modifizieren zu müssen.By the concept of the invention is the adaptation of an existing transmission to a lower input speed so ensured that at lower input speed an equal or higher final speed is made possible without having to modify the existing gear consuming.

Weitere Merkmale sind der Figuren-Beschreibung zu entnehmen. Es zeigen:Further Features are shown in the figure description. Show it:

1 ein Getriebeschema und 1 a transmission scheme and

2 einen Schnitt durch die Splittergruppe. 2 a section through the splinter group.

1: 1 :

Das Zahnrad 1 der Vorwärtswelle 2 weist eine Zähnezahl von 40 auf. Das Zahnrad 3 der Rückwärtswelle 4 weist ebenfalls eine Zähnezahl 40 auf. Das Zahnrad 1 und das Zahnrad 3 stehen in Wirkverbindung mit einem Zahnrad 5 mit der Zähnezahl 47. Dadurch ist es möglich, das Zahnrad 1 und das Zahnrad 3 in der selben Ebene, wie in 2 dargestellt, anzuordnen. In 1 sind die Zahnräder 1 und 3 nicht in der selben Ebene angeordnet. Durch die Verwendung der erfindungsgemäßen Zähnezahlen ist es möglich, die Zahnräder 1 und 3 versetzt oder in der selben Ebene anzuordnen.The gear 1 the forward wave 2 has a number of teeth of 40 on. The gear 3 the reverse wave 4 also has a number of teeth 40 on. The gear 1 and the gear 3 are in operative connection with a gear 5 with the number of teeth 47 , This makes it possible for the gear 1 and the gear 3 in the same plane as in 2 represented to arrange. In 1 are the gears 1 and 3 not arranged in the same plane. By using the numbers of teeth according to the invention, it is possible the gears 1 and 3 offset or in the same plane to arrange.

2: 2 :

Zwischen den Zahnköpfen des Zahnrades 1 und des Zahnrades 3 ist ein Abstand vorhanden, so dass das Zahnrad 1 und das Zahnrad 3 in einer Ebene angeordnet werden können.Between the tooth tips of the gear 1 and the gear 3 There is a gap, so the gear 1 and the gear 3 can be arranged in one plane.
