Abstract

The wheel hub comprises a bearing (2) located in a hub housing. The bearing is axially retained by a ring (3) provided with coding means intended to be read by a sensor able to determine the rotational speed of the wheel.

Description

<Desc/Clms Page number 1> <Desc / Clms Page number 1>

L'invention se rapporte à agencement d'un moyeu de roue de véhicule automobile.  The invention relates to an arrangement of a motor vehicle wheel hub.

L'invention concerne plus particulièrement un agencement d'un moyeu de roue de véhicule automobile comportant un roulement disposé dans un logement du moyeu et des moyens de retenue axiale du roulement.  The invention relates more particularly to an arrangement of a motor vehicle wheel hub comprising a bearing disposed in a housing of the hub and means for axially retaining the bearing.

Classiquement, le roulement est bloqué axialement dans son logement au moyen d'un circlips engagé dans une rainure formée dans le moyeu, au niveau de l'extrémité du logement prévu pour le roulement.  Conventionally, the bearing is locked axially in its housing by means of a circlip engaged in a groove formed in the hub, at the end of the housing provided for the bearing.

Cependant, cet agencement présente un encombrement relativement important, notamment dans une direction parallèle à l'axe de rotation du moyeu En particulier, l'agencement du moyeu présente un encombrement important lorsque le moyeu de roue est pourvu d'un dispositif de détection de la vitesse de rotation de la roue. En effet, les moyens de détection de la vitesse de rotation de la roue comprennent en général une bague magnétisée solidaire du moyeu et apte à coopérer avec des moyens de détection complémentaires disposés en regard de la bague, sur un élément fixe du véhicule.  However, this arrangement has a relatively large size, especially in a direction parallel to the axis of rotation of the hub. In particular, the arrangement of the hub has a large size when the wheel hub is provided with a device for detecting the wheel rotation speed. In fact, the means for detecting the speed of rotation of the wheel generally comprise a magnetized ring integral with the hub and able to cooperate with complementary detection means arranged opposite the ring, on a fixed element of the vehicle.

Un but de la présente invention est de proposer un agencement d'un moyeu de roue de véhicule automobile palliant tout ou partie des inconvénients de l'art antérieur relevés ci-dessus.  An object of the present invention is to provide an arrangement of a wheel hub of a motor vehicle overcoming all or part of the drawbacks of the prior art noted above.

Ce but est atteint par le fait que l'agencement d'un moyeu de roue de véhicule automobile comporte un roulement disposé dans un logement du moyeu, des moyens de retenue axiale du roulement, caractérisé en ce que les moyens de retenue axiale sont constitués d'une bague pourvue de moyens de codage destinés à coopérer avec des moyens formant capteur aptes à déterminer la vitesse de rotation de la roue.  This object is achieved by the fact that the arrangement of a motor vehicle wheel hub comprises a bearing disposed in a housing of the hub, axial bearing retaining means, characterized in that the axial retaining means consist of 'a ring provided with coding means intended to cooperate with sensor means capable of determining the speed of rotation of the wheel.

Par ailleurs, l'invention peut comporter l'une ou plusieurs des caractéristiques suivantes.  Furthermore, the invention may include one or more of the following characteristics.

Figure img00020001

- la bague de codage est emmanchée sur le moyeu, - la bague de codage est constituée d'une feuille métallique en forme d'anneau dont la bordure périphérique est pliée sensiblement à 90 degrés pour permettre son emmanchement sur le moyeu, - la bague comporte une ouverture centrale délimitée par un bord formant une butée axiale pour une extrémité du roulement. - the coding ring is fitted onto the hub, - the coding ring consists of a metal sheet in the form of a ring, the peripheral edge of which is folded substantially at 90 degrees to allow it to be fitted onto the hub, - the ring has a central opening delimited by an edge forming an axial stop for one end of the bearing.

D'autres particularités et avantages apparaîtront à la lecture de la description ci-après, faite en référence à la figure unique, qui représente une vue en coupe longitudinale d'un agencement d'un moyeu de roue de véhicule selon l'invention.  Other particularities and advantages will appear on reading the description below, made with reference to the single figure, which represents a view in longitudinal section of an arrangement of a vehicle wheel hub according to the invention.

Le moyeu 1 illustré à la figure unique (roue non représentée) est un moyeu-disque, c'est-à-dire que le moyeu 1 est formé d'une pièce monobloc avec un disque 4 de frein.  The hub 1 illustrated in the single figure (wheel not shown) is a disc hub, that is to say that the hub 1 is formed in one piece with a brake disc 4.

Bien entendu, l'invention peut s'appliquer également à un moyeu tambour (non représenté). Of course, the invention can also be applied to a drum hub (not shown).

La partie centrale du moyeu 1 comporte une ouverture 5 destinée à accueillir un arbre de transmission non représenté ou une fusée permettant la rotation de l'ensemble.  The central part of the hub 1 has an opening 5 intended to receive a not shown transmission shaft or a rocket allowing the rotation of the assembly.

Un roulement 2 est emmanché dans un logement 6 formé au niveau de l'ouverture 5 du moyeu 1. Le roulement 2 est emmanché dans son logement 6 jusqu'à ce qu'il vienne en butée contre un fond 7.  A bearing 2 is fitted into a housing 6 formed at the opening 5 of the hub 1. The bearing 2 is fitted into its housing 6 until it comes into abutment against a bottom 7.

Une bague 3 pourvue de moyens de codage est emmanchée sur l'extrémité du moyeu 1 qui est tournée vers l'intérieur du véhicule. Plus précisément, la bague 3 de codage est constituée d'une feuille métallique en forme d'anneau dont la bordure périphérique est pliée sensiblement à 90 degrés pour permettre son emmanchement sur le moyeu 1
La bague 3 codée est conformée de façon à assurer le blocage axial du roulement 2 dans son logement 6. C'est-à- A ring 3 provided with coding means is fitted on the end of the hub 1 which faces the interior of the vehicle. More specifically, the coding ring 3 consists of a metal sheet in the form of a ring, the peripheral edge of which is folded substantially at 90 degrees to allow it to be fitted onto the hub 1
The coded ring 3 is shaped so as to ensure the axial locking of the bearing 2 in its housing 6. That is to say

<Desc/Clms Page number 3><Desc / Clms Page number 3>

dire que le bord 8 circulaire intérieur de la bague 3 forme une butée pour une extrémité du roulement 2.  say that the inner circular edge 8 of the ring 3 forms a stop for one end of the bearing 2.

De manière classique, la surface de la bague 3 qui est tournée vers l'intérieur du véhicule comporte les moyens de codage, constitués, par exemple, de pistes magnétiques. Les moyens de codage sont prévus pour coopérer avec des moyens formant capteur (non représentés) disposés sur une partie non-tournante du train du véhicule.  Conventionally, the surface of the ring 3 which faces the interior of the vehicle comprises the coding means, consisting, for example, of magnetic tracks. The coding means are provided to cooperate with sensor means (not shown) arranged on a non-rotating part of the train of the vehicle.

On conçoit donc aisément que l'agencement d'un moyeu de roue selon l'invention a une structure simple, peu encombrante et économique. En particulier, l'invention permet de diminuer le nombre de pièces constitutives de l'agencement (suppression du circlips).  It is therefore easily understood that the arrangement of a wheel hub according to the invention has a simple structure, compact and economical. In particular, the invention makes it possible to reduce the number of component parts of the arrangement (elimination of the circlip).

Enfin, bien que l'invention ait été décrite en liaison avec des modes de réalisation particuliers, elle comprend tous les équivalents techniques des moyens décrits. Finally, although the invention has been described in connection with particular embodiments, it includes all the technical equivalents of the means described.
