Abstract

A joint coupling with homokinetic fixed joints is provided for the connection of manual shift transmission and rear axle in commercial vehicles. The rotation sleeve fixed on the output shaft of the manual shift transmission and the rotation sleeve fixed on the input shaft of the rear axle have internal tooth systems, in which the externally toothed, homokinetic fixed joints, fixed by means of a connecting shaft, are arranged so that they are longitudinally displaceable. Springs are provided between the transmission and rear axle-side bases of the rotation sleeves and the homokinetic fixed joints . Non-rotating covering tubes are fitted on the fixed parts of manual shift transmission and rear axle, on the free ends of which a bellows is fixed, which is connected to a bearing enclosing the connecting shaft.

Description

Die Erfindung bezieht sich auf eine Gelenkkupplung mit homo­ kinetischen Festgelenken, insbesondere an Schaltgetriebe und Hinterachse von Nutzfahrzeugen, wobei der Verbindungsstrang zwischen dem Schaltgetriebe und der Hinterachse nach Patent­ anmeldung P 37 04 143.6 vollständig durch Hülsen- und Fal­ tenbälge abgedeckt ist.The invention relates to an articulated coupling with homo kinetic fixed joints, especially on manual transmissions and Rear axle of commercial vehicles, the connecting line between the manual transmission and the rear axle according to patent registration P 37 04 143.6 completely by sleeve and case bellows is covered.

Der Erfindung liegt die Aufgabe zugrunde, eine gattungsgemä­ ße Einrichtung einfacherer Bauart zu schaffen.The invention has for its object a generic to create a simpler design.

Dies wird erfindungsgemäß dadurch erreicht, daß die auf der Ausgangswelle des Schaltgetriebes befestigte Rotationshülse und die auf der Eingangswelle der Hinterachse befestigte Ro­ tationshülse Innenverzahnungen aufweist, in denen die mit­ tels einer Verbindungswelle fest verbundenen, außen verzahn­ ten homokinetischen Fesgelenke, längsverschieblich angeord­ net sind, daß zwischen den getriebe- und hinterachsseitigen Böden der Rotationshülsen und den homokinetischen Festgelenken Federn vorgesehen sind und daß an den feststehenden Teilen von Schaltgetriebe und Hinterachse rotationsfreie Ab­ deckrohre angebracht sind, an deren freien Enden ein Falten­ balg befestigt ist, dessen Mittelteil mit einem die Verbin­ dungswelle umgreifenden Lager verbunden ist. Solcherart kann auf die beim Gegenstand des Hauptpatentes notwendigen Stütz- und Positionierungslenker zur ständigen Mittenzen­ trierung verzichtet werden.This is achieved according to the invention in that the Output shaft of the gearbox attached rotary sleeve and the Ro attached to the input shaft of the rear axle tion sleeve has internal gears in which the with by means of a connecting shaft firmly connected, external toothing ten homokinetic fixed joints, longitudinally displaceable are net that between the gearbox and rear axle Bottoms of the rotating sleeves and the homokinetic fixed joints Springs are provided and that on the fixed Parts from manual gearbox and rear axle from rotation-free cover tubes are attached, at the free ends of a fold bellows is attached, the middle part with a the verbin is encompassing bearing. Such a way can on the necessary for the subject of the main patent Support and positioning handlebars for constant centering be dispensed with.

Weitere Merkmale und Vorteile der Erfindung sind den Ansprü­ chen, der Zeichnung und der Figurenbeschreibung zu entnehmen. Further features and advantages of the invention are the claims Chen, the drawing and the description of the figures.  

Während des Fahrbetriebes rotieren Rotationshülse 1, die ge­ lenkige Verbindungseinheit, bestehend aus Festgelenk 5, Verbindungswelle 7, Festgelenklager 6 und Rotationshülse 2. Dabei halten die vorgespannten, gegeneinander wirkenden Fe­ dern 8 und 9 die Verbindungseinheit in der Mittellage zwi­ chen Getriebe und Hinterachse.During driving operation, rotation sleeve 1 , the ge articulated connecting unit consisting of fixed joint 5 , connecting shaft 7 , fixed joint bearing 6 and rotating sleeve 2 . The preloaded, counteracting springs 8 and 9 hold the connection unit in the middle position between the transmission and rear axle.

Die Mittellage wird auch in einer starken Ein- oder Ausfe­ dersituation beibehalten. In diesem Fall längen sich die beiden Federn entsprechend dem halben Gelenkkupplungsschiebe­ weg aus. Das Kräftegleichgewicht der gegeneinander wirken­ den Federn sorgt für die Mittenpositionierung der Vebin­ dungseinheit. Die Mittellage des Balges ergibt sich stets durch die Ausfaltcharakteristik. In der Ein- oder Ausfeder­ situation verlängern oder verkürzen sich die diagonal gegen­ überliegenden Segmente des Balges. Sie üben so gegeneinander wirkende gleich große Kräfte aus, so daß die Lagerung an der Wellendurchführung in der Mittenposition gehalten wird. The middle layer is also in a strong in or out maintain the situation. In this case, the two springs corresponding to half the articulated coupling slide away from. The balance of forces that work against each other the springs ensure that the Vebin is positioned in the center unit. The middle position of the bellows always results due to the folding characteristics. In the spring or rebound situation lengthen or shorten diagonally overlying segments of the bellows. So they practice against each other acting equally large forces, so that the storage on the Shaft bushing is held in the middle position.
