Abstract

The invention relates to a positive connection between an input shaft (11) and an inner race (1) of a rolling bearing unit with flange-like outer portions (2, 10) on both races (1, 9), the said connection transmitting a torque for an input part to an output part and being effected by means of a plurality of interengaging, essentially axially oriented projections (16, 17) which project, on the one hand, from the inner race (1) and, on the other hand, from the input shaft (11) or a part (12) connected to the latter. In order to provide a connection by means of which high torques can be transmitted and in which satisfactory centring of the parts upon assembly occurs automatically, the projections (16, 17) which together form an interlocking tooth system are according to the invention arranged on essentially tapered surfaces (15, 18) of the inner race (1) and of the input shaft (11) or a part (12) connected to the latter. <IMAGE>

Description

Formschlüssige Verbindung zwischen einerAntriebswellePositive connection between a drive shaft

und einer Wälzlagereinheit Die Erfindung betrifft eine formschlüssige, ein Drehmoment von einem Antriebsteil auf ein Abtriebsteil übertragende Verbindung nach dem Oberbegriff des Hauptanspruches. and a roller bearing unit The invention relates to a form-fitting, a connection transmitting torque from a drive part to a driven part according to the preamble of the main claim.

Eine solche Verbindung ist beispielsweise durch die DE-OS 25 43 210 bekannt. Bei dieser bekannten Ausführung sind die Vorsprünge in den radial verlaufenden Stirnflächen des Innenringes und eines mit der Welle verbundenen Teils eingearbeitet. Diese Flächen sind wegen des begrenzt zur Verfügung stehenden Bauraumes relativ klein ausgebildet, so daß nur ein begrenztes Drehmoment übertragen werden kann. Auch ist bei der bekannten Ausführung eine genaue Zentrierung der zu verbindenden Teile nur mit einem zusätzlichen Aufwand, z. B. der Anordnung eines zusätzlichen Druckringes, möglich. Such a connection is, for example, from DE-OS 25 43 210 known. In this known embodiment, the projections are in the radially extending Incorporated end faces of the inner ring and a part connected to the shaft. These areas are relative because of the limited space available made small, so that only a limited torque can be transmitted. In the known design, too, is a precise centering of the to be connected Parts only with additional effort, e.g. B. the arrangement of an additional Pressure ring, possible.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Verbindung zu schaffen, mit der hohe Drehmomente übertragen werden können und bei der selbsttätig eine einwandfreie Zentrierung der Teile beim Zusammenbau erfolgt.The present invention is based on the object of a connection to create, with which high torques can be transmitted and automatically the parts are properly centered during assembly.

Diese Aufgabe wird mit der Maßnahme des kennzeichnenden Teiles des Hauptanspruches gelöst.This task is carried out with the measure of the characterizing part of the Main claim solved.

Durch die Anordnung der ineinandergreifenden Vorsprünge auf kegeligen Flächen wird einerseits die Uberdeckungsfläche bzw. die Wirkfläche erhöht und zum anderen erfolgt automatisch eine Selbstzentrierung der Teile beim Zusammenbau.Due to the arrangement of the interlocking projections on tapered Areas on the one hand, the coverage area or the effective area is increased and for others automatically self-center the parts during assembly.

Ein Ausführungsbeispiel der Erfindung soll nachstehend anhand der beiliegenden Zeichnung näher erläutert werden.An embodiment of the invention will be described below with reference to the attached drawing will be explained in more detail.

Die einzige Figur zeigt einen Längsschnitt durch eine angetriebene Radlagerung für ein Kraftfahrzeug. Mit 1 ist der Innenring des Radlagers bezeichnet, der einen radial nach außen gerichteten Flansch 2 aufweist, an dem die nicht dargestellte Bremsscheibe und das Rad befestigt werden. Der Innenring 1 ist mit den Laufbahnen 3 und 4 für die beiden Reihen von Wälzkörpern 5 und 6 versehen. Diese Wälzkörper 5 und 6 wälzen außerdem auf den Laufbahnen 7 und 8 des Außenringes 9 ab. Der Außenring 9 ist ebenfalls mit einem radial nach außen gerichteten Flansch 10 versehen, über dem die gesamte Radlagerung am (nicht dargestellten) Fahrgestell des Kraftfahrzeuges befestigt wird.The only figure shows a longitudinal section through a driven one Wheel bearings for a motor vehicle. 1 with the inner ring of the wheel bearing is referred to, which has a radially outwardly directed flange 2 on which the not shown Brake disc and the wheel are attached. The inner ring 1 is with the raceways 3 and 4 for the two rows of rolling elements 5 and 6 provided. These rolling elements 5 and 6 also roll on the raceways 7 and 8 of the outer ring 9. The outer ring 9 is also provided with a radially outwardly directed flange 10, over the entire wheel bearing on the (not shown) chassis of the motor vehicle is attached.

Mit dem Innenring 1 ist die Antriebswelle 11 über ein Gleichlaufgelenk 12 verbunden. Der Außenkörper 13 des Gleichlaufgelenkes 12 weist einen glockenförmigen, gegen den Innenring 1 gerichteten Ansatz 14 auf, der auf einem kegeligen Abschnitt 15 mit im wesentlichen axial gerichteten Vorsprüngen 16 versehen ist. Diese Vorsprünge 16 greifen in Vorsprünge 17 an einer ebenfalls kegeligen Fläche 18 im Bereich der Endfläche 19 des Innenringes 1 ein.The drive shaft 11 is connected to the inner ring 1 via a constant velocity joint 12 connected. The outer body 13 of the constant velocity joint 12 has a bell-shaped, against the inner ring 1 directed approach 14 on a tapered section 15 is provided with essentially axially directed projections 16. These protrusions 16 engage in projections 17 on a likewise conical surface 18 in the area of End surface 19 of the inner ring 1.

Der Außenkörper 13 des Gleichlaufgelenkes 12 ist mittels eines Schraubenbolzens 20, der eine Bohrung 21 im Boden 22 des Innenringes 1 durchgreift, mit dem Innenring 1 verbunden. Der Schraubenbolzen 20 greift dabei in eine Gewindebohrung 23 im glockenförmigen Ansatz 14 des Aussenkörpers 13 des Gleichlaufgelenkes 12 ein. Beim Zusammenfügen der Teile wird der Außenkörper 13 in die Ausnehmung 24 des Innenringes 1 eingezogen, wobei die Vorsprünge 16 und 17 ineinandergreifen und so eine formschlüssige Verbindung zwischen dem Innenring 1 und dem Außenkörper 13 des Gleichlaufgelenkes schaffen.The outer body 13 of the constant velocity joint 12 is by means of a screw bolt 20, which passes through a bore 21 in the bottom 22 of the inner ring 1, with the inner ring 1 connected. The screw bolt 20 engages in a threaded hole 23 in the bell-shaped Approach 14 of the outer body 13 of the constant velocity joint 12 a. When joining of the parts, the outer body 13 is drawn into the recess 24 of the inner ring 1, wherein the projections 16 and 17 interlock and thus form a positive connection create between the inner ring 1 and the outer body 13 of the constant velocity joint.
