Abstract
Description
La présente invention concerne un démarreur de véhicule automobile.The present invention relates to a motor vehicle starter.
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 entraîneur 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'entraînement, 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 killer starter comprising a launcher on which acts one end of a control lever, and which comprises a driver whose body comprises a sleeve which is slidably mounted on the launcher shaft and of which a first end extends radially outwards by a disk-shaped wall which cooperates 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'entraînement 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 drive ring 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 radial shoulder.
La maîtrise 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.The control of a determined radial clearance between the internal diameter of the hole of the washer and the external diameter of the cylindrical mounting surface is necessary so as to be able to reliably effect the fixing of 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 radial clearance between the washer and the cylindrical mounting surface to 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 placing the washer on the sleeve and an axial thrust operation of the washer to bring it into 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 force the value of which varies according to the dimensional tolerances of the 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 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 object of the invention is to propose a new design of a starter of the type mentioned above which makes it possible to perform this manual installation operation on a first station for placing the washer, the axial thrust operation in abutment against the radial shoulder 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 provides a starter of the type mentioned above, characterized in that the second free end of the sleeve of the body of the launcher comprises at least one positioning range before mounting whose diameter is less than that of the cylindrical range of mounting.
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.
- the positioning surface is a cylindrical section;
- the cylindrical mounting surface and the cylindrical positioning surface are interconnected 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 apparaîtront 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 entraîneur 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 apparaître 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.
