Abstract

The telescopic steering column has two parts (2,3) that can slide axially one relative to the other. The two parts have complementary ridges and grooves (4,5) that transmit rotary motion. Play between the two parts is absorbed an elastic ring(7,8,9) made of a metal. The ring is corrugated (7a,7b), with the profile of the corrugations complementary to the ridges and grooves of the two parts of the steering column. The ring is fitted between the two parts of the steering column by compression, ensuring it is pre-stressed to absorb play. A lock (10) provides axial location for the ring.

Description

La présente invention concerne un arbre de direction télescopique, notamment pour véhicule automobile. The present invention relates to a telescopic steering shaft, in particular for a motor vehicle.

On connaît déjà dans l'état de la technique, un certain nombre d'arbres de direction télescopiques pour véhicule automobile, qui comportent deux portions d'arbre montées déplaçables à coulissement l'une dans l'autre et comportant des cannelures complémentaires. C'est ainsi que la portion d'arbre externe comporte des cannelures internes, tandis que la portion d'arbre interne comporte des cannelures externes complémentaires à celles de la portion d'arbre externe, ces cannelures étant adaptées pour coopérer les unes avec les autres afin d'assurer un guidage en coulissement axial de ces portions d'arbre l'une dans l'autre. A number of telescopic steering shafts for a motor vehicle are already known in the state of the art, which comprise two shaft portions mounted so that they can slide in one another and have complementary grooves. Thus, the outer shaft portion has internal splines, while the inner shaft portion has external splines complementary to those of the outer shaft portion, these splines being adapted to cooperate with each other. in order to ensure axial sliding guidance of these shaft portions one inside the other.

De plus, des moyens de rattrapage des jeux de montage des portions d'arbre sont interposés entre cellesci. In addition, means for adjusting the mounting clearances of the shaft portions are interposed therebetween.

On a déjà développé dans l'état de la technique, un certain nombre de modes de réalisation de ces moyens de rattrapage des jeux. We have already developed in the prior art, a number of embodiments of these games take-up means.

C'est ainsi par exemple que ces moyens peuvent comporter des bagues en matière plastique montées sous contrainte entre les portions d'arbre et permettant de rattraper les jeux. Thus, for example, these means may include plastic rings mounted under stress between the shaft portions and making it possible to make up for the clearances.

Par ailleurs, on a également disposé entre les portions d'arbre des moyens de rattrapage des jeux se présentant sous la forme de lames élastiques en matériau métallique. Furthermore, there are also disposed between the shaft portions means for taking up the play in the form of elastic blades of metallic material.

Cependant, toutes ces structures présentent un certain nombre d'inconvénients notamment au niveau de leur difficulté de montage, de leur coût de réalisation et de leur fiabilité. However, all of these structures have a certain number of drawbacks, particularly in terms of their difficulty of assembly, their cost of production and their reliability.

Le but de l'invention est donc de résoudre ces problèmes.  The object of the invention is therefore to solve these problems.

A cet effet, l'invention a pour objet un arbre de direction télescopique, notamment pour véhicule automobile, du type comportant deux portions d'arbre montées déplaçables à coulissement l'une dans l'autre et comportant des cannelures complémentaires et entre lesquelles sont disposés des moyens de rattrapage des jeux, caractérisé en ce que les moyens de rattrapage des jeux comportent au moins une bague élastique en matériau métallique comportant des ondulations de forme complémentaire aux cannelures des portions d'arbre et montée sous contrainte entre les portions d'arbre pour assurer un rattrapage des jeux entre celles-ci. To this end, the subject of the invention is a telescopic steering shaft, in particular for a motor vehicle, of the type comprising two shaft portions mounted so that they can slide one inside the other and comprising complementary grooves and between which are disposed. play take-up means, characterized in that the play take-up means comprise at least one elastic ring of metallic material having corrugations of shape complementary to the grooves of the shaft portions and mounted under stress between the shaft portions for ensure a catch up between the games.

Avantageusement, la bague comporte en regard de chaque arête vive des cannelures, une zone d'appui incurvée vers l'arête. Advantageously, the ring comprises, opposite each sharp edge of the grooves, a support zone curved towards the edge.

L'invention sera mieux comprise à l'aide de la description qui va suivre donnée uniquement à titre d'exemple et faite en référence aux dessins annexés, sur lesquels
- la figure 1 représente une vue en perspective éclatée d'un arbre de direction télescopique selon l'invention,
- la figure 2 représente une vue en coupe d'un tel arbre, illustrant l'implantation de moyens de rattrapage de jeux, et
- la figure 3 représente une vue en perspective d'une variante de réalisation de moyens de rattrapage de jeux entrant dans la constitution d'un arbre de direction selon l'invention.The invention will be better understood with the aid of the description which follows, given solely by way of example and made with reference to the appended drawings, in which
FIG. 1 represents an exploded perspective view of a telescopic steering shaft according to the invention,
FIG. 2 represents a sectional view of such a tree, illustrating the installation of play take-up means, and
- Figure 3 shows a perspective view of an alternative embodiment of play take-up means forming part of a steering shaft according to the invention.

On reconnaît en effet sur les figures 1 et 2, un arbre de direction télescopique notamment pour véhicule automobile, désigné par la référence générale 1. It is recognized in FIGS. 1 and 2, a telescopic steering shaft, in particular for a motor vehicle, designated by the general reference 1.

Cet arbre de direction comporte deux portions d'arbre montées déplaçables à coulissement l'une dans l'autre.  This steering shaft has two shaft portions mounted to slide so that they can slide into one another.

Ces portions d'arbre sont désignées par les références générales 2 et 3 respectivement. These shaft portions are designated by the general references 2 and 3 respectively.

Ces portions d'arbre comportent des cannelures complémentaires qui sont adaptées pour coopérer les unes avec les autres afin d'assurer un guidage en coulissement axial des portions d'arbre l'une par rapport à l'autre. These shaft portions have complementary grooves which are adapted to cooperate with each other in order to provide axial sliding guidance of the shaft portions relative to one another.

C'est ainsi par exemple que la portion d'arbre interne 2 comporte des cannelures externes 4 tandis que la portion d'arbre externe 3 comporte des cannuelures internes 5 de forme complémentaire à celles de la portion d'arbre interne 2. Thus, for example, the internal shaft portion 2 has external splines 4 while the external shaft portion 3 has internal grooves 5 of shape complementary to those of the internal shaft portion 2.

Cette structure est bien connue dans l'état de la technique de sorte qu'on ne la décrira pas plus en détail par la suite. This structure is well known in the state of the art so that it will not be described in more detail later.

Par ailleurs, des moyens de rattrapage des jeux d'assemblage sont également interposés entre ces portions d'arbre. Furthermore, means for adjusting the assembly clearances are also interposed between these shaft portions.

Ces moyens sont désignés par la référence générale 6 sur ces figures et comprennent par exemple au moins une bague élastique en matériau métallique comportant des ondulations de forme complémentaire aux cannelures des portions d'arbre et montée sous contrainte entre ces portions d'arbre pour assurer un rattrapage des jeux entre celles-ci. These means are designated by the general reference 6 in these figures and comprise for example at least one elastic ring of metallic material comprising corrugations of shape complementary to the grooves of the shaft portions and mounted under stress between these shaft portions to ensure a catching up of games between them.

Dans l'exemple de réalisation représentée sur la figure 1, deux bagues 7 et 8 sont disposées entre les portions d'arbre à distance l'une de l'autre. In the embodiment shown in Figure 1, two rings 7 and 8 are arranged between the shaft portions at a distance from each other.

Comme on peut le voir plus clairement sur la figure 2, une telle bague par exemple 7, comporte des ondulations 7a, 7b de forme complémentaire aux cannelures des portions d'arbre et est donc interposée entre ces portions d'arbre pour assurer le rattrapage des jeux. La ou chaque bague est en effet montée sous contrainte entre ces portions d'arbre pour assurer ce rattrapage des jeux de montage des portions d'arbre l'une dans l'autre.  As can be seen more clearly in FIG. 2, such a ring, for example 7, has corrugations 7a, 7b of shape complementary to the grooves of the shaft portions and is therefore interposed between these shaft portions to ensure that the games. The or each ring is in fact mounted under stress between these shaft portions to ensure this take-up of the mounting clearances of the shaft portions one inside the other.

Par ailleurs, la ou chaque bague peut également comporter en regard de chaque arête vive des cannelures, une zone d'appui 7c incurvée vers cette arête, permettant d'augmenter la surface de contact entre cette bague et les cannelures de la portion d'arbre correspondante afin de réduire l'usure de celles-ci. Furthermore, the or each ring may also include, opposite each sharp edge of the grooves, a bearing area 7c curved towards this edge, making it possible to increase the contact surface between this ring and the grooves of the shaft portion to reduce wear and tear.

On conçoit alors qu'une telle bague du fait de cette forme particulière, assure un excellent rattrapage des jeux angulaires et radiaux entre les portions d'arbre tout en assurant un coulissement aisé des deux portions d'arbre l'une par rapport à l'autre. It will then be understood that such a ring, due to this particular shape, ensures excellent compensation for the angular and radial clearances between the shaft portions while ensuring easy sliding of the two shaft portions, one relative to the other.

Par ailleurs, la demanderesse a constaté qu'une telle bague permet de définir généralement trois zones d'appui à peu près décalées de 120 les unes par rapport aux autres, entre la portion d'arbre externe, la bague et la portion d'arbre interne. Furthermore, the Applicant has found that such a ring generally makes it possible to define three bearing zones approximately offset from one another by 120, between the outer shaft portion, the ring and the shaft portion internal.

Dans l'exemple de réalisation qui vient d'être décrit en regard des figures 1 et 2, deux bagues disposées à distance l'une de l'autre sont interposées entre les portions d'arbre interne et externe. In the embodiment which has just been described with reference to Figures 1 and 2, two rings arranged at a distance from one another are interposed between the inner and outer shaft portions.

I1 va de soi comme on peut le voir sur la figure 3, qu'une bague unique allongée peut également être utilisée, cette bague étant désignée par la référence générale 9 sur cette figure 3 et comportant par exemple des ajourages. It goes without saying, as can be seen in FIG. 3, that a single elongated ring can also be used, this ring being designated by the general reference 9 in this FIG. 3 and comprising for example openings.

De plus, on notera qu'il est également prévu des moyens de maintien en position axiale de la ou de chaque bague entre les portions d'arbre. De façon classique, de tels moyens peuvent par exemple comporter des pions ou autres d'une portion d'arbre, comme par exemple des pions de la portion d'arbre interne 2, désignés par la référence générale 10 sur la figure 1. In addition, it will be noted that there is also provided means for holding the axial position of the or each ring between the shaft portions. Conventionally, such means may for example comprise pins or others of a shaft portion, such as for example pins of the internal shaft portion 2, designated by the general reference 10 in FIG. 1.

Bien entendu, d'autres modes de réalisation de ces moyens de maintien en position axiale de la ou de chaque bague peuvent être envisagés.  Of course, other embodiments of these means for holding the axial position of the or each ring can be envisaged.

Ainsi par exemple, ces moyens peuvent comporter des organes en matière plastique surmoulés sur la portion d'arbre interne.  Thus, for example, these means may include plastic members overmolded on the internal shaft portion.
