Description

Die Erfindung betrifft ein Gleichlauf-Festgelenk zum Übertragen von Kräften bzw. Momenten zwischen einem äußeren Gelenkkörper und einem inneren Gelenkkörper der Gelenkverbindung zweier Wellen.The invention relates to a constant velocity fixed joint for transmitting forces or moments between an outer joint body and an inner joint body the articulation of two shafts.

Es ist ein Gleichlauf-Festgelenk zum Übertragen von Kräften und Momenten zwischen einem äußeren und einem inneren Gelenkkörper mit für Steuerung und Momentenübertragung unterschiedlichen Bauelementen bekannt (DE-GM 66 04 060). Das Gleichlauf-Festgelenk weist nur je zwei Steuer- und Momentenübertragungselemente auf, wodurch seine Einsatzmöglichkeiten wegen der begrenzten Drehmomentübertragung sehr eingeschränkt sind. Die spezifische Bauart läßt nicht mehr als je zwei Steuer- und Drehmomentübertragungselemente zu.It is a constant velocity fixed joint for transferring forces and moments between an outer and an inner joint body with for control and Torque transmission different components known (DE-GM 66 04 060). The constant velocity fixed joint only has two control and torque transmission elements on, which is because of its uses the limited torque transmission are very limited. The specific Type leaves no more than two control and torque transmission elements to.

Der Erfindung liegt die Aufgabe zugrunde, ein Gleichlauf-Gelenk mit wesentlich größerer Drehmomentübertragung und höherer Lebensdauer bei hohen Beugungswinkeln zu schaffen.The invention has for its object to provide a constant velocity joint greater torque transmission and longer service life at high diffraction angles to accomplish.

Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst.This object is solved by the features of claim 1.

Solcherart wird durch die Eigenart der Konstruktion, die vier Steuerelemente und gleichzeitig vier Kraftübertragungselemente ermöglicht, eine höhere Lebensdauer des Gelenks erzielt, dabei ergibt sich eine reibungsarme Zentrierung von äußerem und innerem Gelenkkörper über die Kugeln bei gleichzeitig hoher Drehmomentenübertragung über die Nadeln oder Gleitlager. Indem die Kugeln von den Innenringen umgriffen werden, wird eine Linienberührung erzielt, die die Übertragung hoher Steuerkräfte zuläßt und zu günstiger Schmierfilmbildung zwischen Kugeln und Innenringen führt.Such is due to the nature of the construction, the four controls and allows four power transmission elements simultaneously, a longer service life achieved of the joint, this results in a low-friction centering from the outside and inner joint body via the balls with high torque transmission at the same time over the needles or plain bearings. By placing the balls of the inner rings are gripped, a line contact is achieved which Allows transmission of high control forces and favorable lubrication film formation between balls and inner rings.

The yoke-like carrier 8, 8 'are supported radially against one another via needle bearings 15 and axially via needle bearings 16, 16 '.

Der äußere Gelenkkörper 1 ist an seiner zur Montage der Innenteile notwendig offenen Seite mittels eines anschraubbaren Flansches 6 geschlossen. Am inneren Gelenkkörper 2 ist über z. B. Kerbverzahnung und Sicherungsring eine Verbindungswelle 7 befestigt.The outer joint body 1 is closed on its side which is necessary for the assembly of the inner parts by means of a screwable flange 6 . On the inner joint body 2 is z. B. serration and locking ring a connecting shaft 7 attached.

Zur Montageerleichterung werden mindestens zwei Rollbahnen zum Einschieben der Rollen so gestaltet, daß eine axiale Verschiebung des jeweiligen jochartigen Trägers möglich ist.To make installation easier, at least two roller conveyors are pushed in of the rollers designed so that an axial displacement of the respective yoke-like Carrier is possible.

Bei einer anderen, nicht dargestellten Ausführung der Erfindung lassen sich die Kugeln 5 und die Rillen 3, 3′, 4, 4′ durch eine an sich bei Verschiebe-Gleichlaufgelenken bekannte Schräggestaltung der Rollbahnen 13, 14 ersparen.In another, not shown embodiment of the invention, the balls 5 and the grooves 3, 3 ', 4, 4' can be saved by an inclined configuration of the runways 13, 14 which is known per se in sliding constant velocity joints.
