Description

La présente invention concerne un démarreur de véhicule automobile.The present invention relates to a vehicle starter automobile.

L'invention concerne plus particulièrement un démarreur du tue comportant un lanceur sur lequel agit une extrémité d'un levier de commande, et qui comprend un entraíneur dont le corps comporte un manchon qui est monté coulissant sur l'arbre du lanceur et dont une première extrémité se prolonge radialement vers l'extérieur par une paroi en forme de disque qui coopère avec une rondelle d'entraínement, agencée au voisinage de la seconde extrémité libre du manchon, pour délimiter un logement qui reçoit l'extrémité du levier de commande.The invention relates more particularly to a starter of the kills comprising a launcher on which acts one end of a control lever, and which comprises a driver whose body has a sleeve which is slidably mounted on the shaft of the launcher and whose first end extends radially outwards by a cooperating disc-shaped wall with a drive washer, arranged in the vicinity of the second free end of the sleeve, to delimit a housing which receives the end of the control lever.

Selon une conception connue, la rondelle ou bague d'entraínement est montée sur une portée cylindrique de montage formée au voisinage de la seconde extrémité libre du manchon avec un jeu radial déterminé et en appui axial contre un épaulement radial.According to a known design, the washer or ring drive is mounted on a cylindrical mounting surface formed in the vicinity of the second free end of the sleeve with a determined radial clearance and in axial support against a shoulder radial.

La maítrise d'un jeu radial déterminé entre le diamètre intérieur du trou de la rondelle et le diamètre extérieur de la portée cylindrique de montage est nécessaire de manière à pouvoir effectuer de manière fiable la fixation de la rondelle par soudage avec un équipement laser.Control of a determined radial clearance between the diameter inside the washer hole and the outside diameter of the cylindrical mounting surface is necessary so that reliably secure the washer by welding with laser equipment.

A cet effet, il est par exemple nécessaire de limiter le jeu radial entre la rondelle et la portée cylindrique de montage à un maximum de 0,10 mm.For this purpose, it is for example necessary to limit the clearance radial between the washer and the cylindrical mounting surface at a maximum of 0.10 mm.

Il en résulte un léger serrage occasionnel qui nécessite une mise en place de la rondelle sur le manchon et une opération de poussée axiale de la rondelle pour l'amener en position axiale contre l'épaulement radial avant l'opération de soudage.This results in a slight occasional tightening which requires a placement of the washer on the sleeve and an operation of axial thrust of the washer to bring it to the axial position against the radial shoulder before the welding operation.

Une telle opération qui nécessite un effort de poussée dont la valeur varie en fonction des tolérances dimensionnelles des pièces est impossible à effectuer manuellement.Such an operation which requires a pushing effort of which the value varies according to the dimensional tolerances of parts is impossible to perform manually.

Pour des raisons de rationalisation de la production, il est apparu souhaitable de pouvoir effectuer la mise en place de la rondelle sur le manchon, avant l'opération de soudage, par une opération de pose manuelle.For reasons of rationalization of production, it is appeared desirable to be able to carry out the installation of the washer on the sleeve, before the welding operation, by a manual installation operation.

L'invention a pour but de proposer une nouvelle conception d'un démarreur du type mentionné précédemment qui permet d'effectuer cette opération de pose manuelle sur un premier poste de mise en place de la rondelle, l'opération de poussée axiale en butée contre l'épaulement radial pouvant être effectuée sur un second poste avec des moyens automatisés.The invention aims to propose a new design a starter of the type mentioned above which allows to perform this manual installation operation on a first post of placing the washer, the axial thrust operation in stop against the radial shoulder which can be performed on a second station with automated means.

Dans ce but, l'invention propose un démarreur du type mentionné précédemment, caractérisé en ce que la seconde extrémité libre du manchon du corps du lanceur comporte au moins une portée de positionnement avant montage dont le diamètre est inférieur à celui de la portée cylindrique de montage.To this end, the invention proposes a starter of the type previously mentioned, characterized in that the second free end of the launcher body sleeve has at least a positioning range before mounting whose diameter is lower than that of the cylindrical mounting surface.

Selon d'autres caractéristiques de l'invention :

  • la portée de positionnement est un tronçon cylindrique ;
  • la portée cylindrique de montage et la portée cylindrique de positionnement sont reliées entre elles par un tronçon intermédiaire cylindrique dont le diamètre est compris entre ceux des portées cylindriques de montage et de positionnement ;
  • la portée cylindrique de montage et la portée cylindrique de positionnement sont reliées entre elles par un tronçon intermédiaire conique ;
  • selon une variante, la portée de positionnement est un tronçon conique ;
  • en position de montage, la rondelle est fixée sur le manchon par soudage laser.
According to other characteristics of the invention:
  • the positioning surface is a cylindrical section;
  • the cylindrical mounting surface and the cylindrical positioning surface are connected together by a cylindrical intermediate section whose diameter is between those of the cylindrical mounting and positioning surfaces;
  • the cylindrical mounting surface and the cylindrical positioning surface are interconnected by a conical intermediate section;
  • according to a variant, the positioning surface is a conical section;
  • in the mounting position, the washer is fixed to the sleeve by laser welding.

D'autres caractéristiques et avantages de l'invention apparaítront à la lecture de la description détaillée qui va suivre pour la compréhension de laquelle on se reportera au dessin annexé dans lequel :

  • La figure 1 est une vue en coupe axiale partielle d'un corps d'un entraíneur d'un démarreur réalisé conformément aux enseignements de l'invention ;
  • la figure 2 est une vue à plus grande échelle du tronçon d'extrémité libre du manchon du corps de lanceur illustré sur la figure 1 qui fait apparaítre un premier mode de réalisation de l'invention ;
  • les figures 3 et 4 sont des vues similaires à celles de la figure 2 qui illustrent deux autres modes de réalisation de l'invention.
Other characteristics and advantages of the invention will appear on reading the detailed description which follows for the understanding of which reference will be made to the appended drawing in which:
  • Figure 1 is a partial axial sectional view of a body of a driver of a starter made in accordance with the teachings of the invention;
  • Figure 2 is an enlarged view of the free end section of the sleeve of the launcher body illustrated in Figure 1 which shows a first embodiment of the invention;
  • Figures 3 and 4 are views similar to those of Figure 2 which illustrate two other embodiments of the invention.

On a représenté sur la figure 1 un entraíneur 10 pour un lanceur d'un démarreur (non représenté) d'un moteur à combustion destiné notamment à équiper un véhicule automobile.FIG. 1 shows a trainer 10 for a launcher of a starter (not shown) of a combustion engine intended in particular to equip a motor vehicle.

Le corps de l'entraíneur est constitué pour l'essentiel par un manchon cylindrique creux 12 comportant des cannelures formées en creux 14 dans sa surface périphérique et qui sont prévues pour coopérer avec des cannelures complémentaires formées sur l'arbre du lanceur (non représenté) du démarreur.The coach's body is mainly made up of a hollow cylindrical sleeve 12 having grooves formed recessed 14 in its peripheral surface and which are provided for cooperate with complementary grooves formed on the shaft of the starter (not shown) of the starter.

Une première extrémité axiale 16 du manchon 12 se prolonge radialement vers l'extérieur par une paroi en forme de disque 18 dont le bord libre se prolonge axialement par une collerette annulaire cylindrique 20.A first axial end 16 of the sleeve 12 is extended radially outwards by a disc-shaped wall 18 the free edge of which is extended axially by a flange cylindrical annular 20.

La paroi 18 et la collerette 20 délimitent un espace cylindrique creux qui reçoit des moyens d'entraínement unidirectionnels (non représentés).The wall 18 and the flange 20 define a space cylindrical hollow which receives means of drive unidirectional (not shown).

Les déplacements axiaux de l'entraíneur sont assurés au moyen d'un levier de commande (non représenté) dont une extrémité libre en forme de fourchette est reçue dans un logement qui est délimité par la paroi radiale en forme de disque 18 et par la face en vis-à-vis 22 d'une rondelle 24 qui est fixée par soudage laser au voisinage de la seconde extrémité libre 26 du manchon 12.The axial displacements of the coach are ensured by means a control lever (not shown) with one free end fork-shaped is received in a housing which is delimited by the disk-shaped radial wall 18 and by the opposite face 22 of a washer 24 which is fixed by welding laser in the vicinity of the second free end 26 of the sleeve 12.

A cet effet, la rondelle 24 comporte un trou circulaire 28 qui est monté avec un léger serrage radial sur une portée cylindrique de montage 30.For this purpose, the washer 24 has a circular hole 28 which is mounted with a slight radial tightening on a span mounting cylinder 30.

La position axiale de la rondelle 24 par rapport au manchon 12 est déterminée par un épaulement radial 32 formé dans le manchon 12 contre lequel la face 22 de la rondelle 24 est en butée axiale.The axial position of the washer 24 relative to the sleeve 12 is determined by a radial shoulder 32 formed in the sleeve 12 against which the face 22 of the washer 24 is in axial stop.

La portée cylindrique de montage 30 présente un diamètre extérieur D indéterminé qui, en association avec le diamètre intérieur du trou 28 de la rondelle 24 définit un serrage des deux éléments.The cylindrical mounting surface 30 has a diameter exterior D indeterminate which, in association with the diameter inside the hole 28 of the washer 24 defines a tightening of the two elements.

Conformément à l'invention, et comme on peut le voir, dans un premier mode de réalisation, sur la figure 2, l'extrémité libre 26 du manchon 12 comporte une portée de positionnement 34 dont le diamètre extérieur D2 est inférieur au diamètre D1 de la portée cylindrique de montage 30.According to the invention, and as can be seen, in a first embodiment, in FIG. 2, the free end 26 of the sleeve 12 has a positioning surface 34 whose outer diameter D2 is less than the diameter D1 of the span mounting cylinder 30.

Dans ce premier mode de réalisation, les portées cylindriques de positionnement 34 et de montage 30 sont reliées entre elles par un tronçon intermédiaire de liaison conique 36.In this first embodiment, the cylindrical spans positioning 34 and mounting 30 are interconnected by an intermediate conical link section 36.

Grâce à cet agencement selon l'invention, il est possible à un opérateur de venir positionner la rondelle 24 sur la portée cylindrique de positionnement 34 sans effet de serrage puis de transférer l'ensemble vers un poste de mise en place de la rondelle en appui contre la butée axiale constituée par l'épaulement radial 32.Thanks to this arrangement according to the invention, it is possible to an operator to position the washer 24 on the bearing cylindrical positioning 34 without clamping effect and then transfer the assembly to a workstation washer bearing against the axial stop constituted by the radial shoulder 32.

L'opération de poussée axiale de la rondelle est facilitée, depuis la portée de positionnement 34 vers la portée de montage 30 grâce au tronçon intermédiaire 36.The axial thrust operation of the washer is facilitated, from positioning range 34 to the mounting range 30 thanks to the intermediate section 36.

Dans le second mode de réalisation illustré sur la figure 3, la portée de positionnement 34 est une portée conique qui présente un diamètre D2, sensiblement à mi-longueur, correspondant au diamètre D2 de la portée cylindrique de positionnement illustrée sur la figure 2 qui permet ici encore d'effectuer un positionnement sans serrage de la rondelle avant l'opération de mise en place sur la portée cylindrique de montage 30.In the second embodiment illustrated in FIG. 3, the positioning scope 34 is a conical scope which has a diameter D2, substantially mid-length, corresponding to the diameter D2 of the cylindrical seat of positioning illustrated in Figure 2 which again allows perform a positioning without tightening the front washer the installation operation on the cylindrical mounting surface 30.

Enfin, le troisième mode de réalisation illustré à la figure 4 est similaire à celui du premier mode de réalisation illustré à la figure 2, le tronçon intermédiaire de liaison 36 entre la portée cylindrique de positionnement 34 et la portée cylindrique de montage 32 étant ici un tronçon intermédiaire cylindrique dont le diamètre extérieur D3 compris entre les diamètres extérieurs D2 et D1 des portées cylindriques 34 et 32.Finally, the third embodiment illustrated in Figure 4 is similar to that of the first embodiment illustrated in Figure 2, the intermediate connecting section 36 between the cylindrical bearing seat 34 and the cylindrical seat mounting 32 here being a cylindrical intermediate section of which the outside diameter D3 between the outside diameters D2 and D1 of the cylindrical spans 34 and 32.
