Des exemples de conception d'un tel type de démarreur sont par exemple illustrés dans le document FR-A-2.673.247 dans lequel le châssis du démarreur comporte une plaque transversale s'étendant dans un plan perpendiculaire aux axes de l'actionneur et du moteur, et un nez de démarreur.Examples of the design of such a type of starter are for example illustrated in the document FR-A-2,673,247 in which the starter chassis comprises a transverse plate extending in a plane perpendicular to the axes of the actuator and of the engine, and a starter nose.

Le levier d'actionnement y est réalisé sous la forme d'une pièce dont la partie centrale est traversée par un axe d'articulation dont les extrémités sont reçues dans une pièce formant palier ayant une silhouette d'étrier et qui est rapportée sur la plaque intermédiaire du châssis du démarreur. Les opérations d'assemblage et de montage du levier d'actionnement en vue de permettre son pivotement sont particulièrement complexes et coûteuses.The actuating lever is produced therein in the form of a part, the central part of which is crossed by a hinge pin, the ends of which are received in a part forming a bearing having a stirrup silhouette and which is attached to the plate. starter frame. The assembly and mounting operations of the actuating lever in order to allow its pivoting are particularly complex and costly.

Il existe également des conceptions dans lesquelles le carter de l'actionneur électromagnétique et le carter du moteur électrique sont fixés directement par vissage sur le nez du démarreur, la pièce d'articulation du levier d'actionnement étant elle-même fixée entre les carters de l'actionneur électromagnétique et du moteur électrique.There are also designs in which the casing of the electromagnetic actuator and the casing of the electric motor are fixed directly by screwing to the nose of the starter, the articulation part of the actuating lever being itself fixed between the casings of the electromagnetic actuator and the electric motor.

La présente invention a pour but de proposer une conception de démarreur du type mentionné précédemment, dans laquelle les moyens pour permettre le montage pivotant du levier d'actionnement sont de conception particulièrement simple et permettent des opérations d'assemblage réduites et facilement automatisables.The object of the present invention is to propose a starter design of the type mentioned above, in which the means for enabling the pivoting mounting of the actuating lever are of particularly simple design and allow reduced assembly operations and easily automated.

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 aux dessins annexés dans lesquels :

  • La figure 1 est une vue en coupe partielle, avec des arrachements partiels, selon un plan contenant les axes de l'actionneur électromagnétique et du moteur électrique ; et

Other features and benefits of the invention will appear on reading the detailed description which follows for the understanding of which reference will be made to the appended drawings in which:
  • Figure 1 is a partial sectional view, with partial cutaway, along a plane containing the axes of the electromagnetic actuator and the electric motor; and
  • Figure 2 is an exploded perspective view on a larger scale of the main components of the articulation means of the actuating lever of the starter launcher, made in accordance with the teachings of the invention.

Le démarreur 10 illustré à la figure 1 comporte un châssis de démarreur dont l'élément principal est un nez de démarreur 11 réalisé sous la forme d'une pièce moulée sur lequel sont fixés un actionneur électromagnétique 12 et un moteur électrique 14.The starter 10 illustrated in FIG. 1 comprises a starter frame, the main element of which is a starter nose 11 produced in the form of a molded part on which an electromagnetic actuator 12 and an electric motor 14 are fixed.

La partie avant épaulée 16 du carter 18 de l'actionneur électromagnétique 12 est emboîtée dans une partie correspondante de la face arrière 20 du nez de démarreur 11 tandis qu'une partie avant 22 du carter 24 du moteur électrique 14 est également reçue dans une partie correspondante (non représentée) du nez de démarreur 11.The stepped front part 16 of the casing 18 of the electromagnetic actuator 12 is fitted into a corresponding part of the rear face 20 of the starter nose 11 while a front part 22 of the casing 24 of the electric motor 14 is also received in a part corresponding (not shown) of the starter nose 11.

L'actionneur électromagnétique 12 et le moteur électrique 14 peuvent être fixés au nez de démarreur 11 par des vis de fixation (non représentées).The electromagnetic actuator 12 and the electric motor 14 can be fixed to the starter nose 11 by fixing screws (not shown).

Le moteur électrique 14, qui peut également être un motoréducteur, comporte un arbre de sortie, ou arbre d'induit 26, dont l'extrémité libre 28 qui fait saillie à la partie avant du carter 24 et qui est reçue dans le nez de démarreur 11 porte un lanceur 30 lié en rotation à l'arbre et qui peut être déplacé axialement le long de cet arbre par l'intermédiaire d'un levier d'actionnement pivotant 32 dont la commande est assurée par l'actionneur électromagnétique 12.The electric motor 14, which can also be a geared motor, comprises an output shaft, or armature shaft 26, the free end 28 of which projects from the front part of the casing 24 and which is received in the starter nose 11 carries a launcher 30 linked in rotation to the shaft and which can be moved axially along this shaft by means of a pivoting actuating lever 32 whose control is ensured by the electromagnetic actuator 12.

Le levier d'actionnement 32 est monté pivotant autour d'un axe géométrique X-X qui est perpendiculaire au plan de la figure 1 contenant l'axe de rotation de l'arbre d'induit 26 du moteur électrique 14 et l'axe longitudinal de l'organe de sortie 34 de l'actionneur électromagnétique 12.The actuating lever 32 is pivotally mounted about a geometric axis XX which is perpendicular to the plane of Figure 1 containing the axis of rotation of the armature shaft 26 of the electric motor 14 and the longitudinal axis of l output member 34 of the electromagnetic actuator 12.

L'actionneur électromagnétique 12 est d'une structure connue, qui ne sera pas décrite en détails et permet, outre l'alimentation en énergie électrique du moteur 14 par un système appelé contacteur, de provoquer le pivotement du levier d'actionnement 32 par l'intermédiaire de son organe de sortie 34 dont l'extrémité libre porte une goupille transversale 36 qui est reçue dans une rainure 38 formée à l'extrémité supérieure 40 du levier d'actionnement 32.The electromagnetic actuator 12 is of a known structure, which will not be described in detail and allows, in addition to the supply of electrical energy to the motor 14 by a system called contactor, to cause the pivoting of the actuating lever 32 by l through its outlet member 34, the free end of which carries a transverse pin 36 which is received in a groove 38 formed at the upper end 40 of the actuating lever 32.

La partie inférieure 42 du levier d'actionnement 32 présente une forme de fourche qui coopère avec une portée de commande 44 du lanceur 30.The lower part 42 of the actuating lever 32 has a form of fork which cooperates with a control range 44 of the launcher 30.

On décrira maintenant, en référence aux figures 1 et 2, les moyens d'articulation du levier 32 permettant son pivotement autour d'un axe géométrique fixe X-X.We will now describe, with reference to Figures 1 and 2, the means of articulation of the lever 32 allowing its pivoting about a fixed geometric axis X-X.

Dans le mode de réalisation illustré sur les figures, le levier 32 est une pièce réalisée par moulage en matière plastique et son axe d'articulation est constitué par deux tronçons opposés 46 d'un axe cylindrique qui s'étendent depuis des faces opposées du corps du levier 32.In the embodiment illustrated in the figures, the lever 32 is a part made by plastic molding and its hinge axis is constituted by two opposite sections 46 of a cylindrical axis which extend from opposite faces of the body lever 32.

Chaque tronçon d'axe 46 est monté à rotation dans un palier en deux parties.Each axis section 46 is rotatably mounted in a two-part bearing.

Chaque palier comporte un premier demi-palier cylindrique concave 48 et un second demi-palier cylindrique concave complémentaire 50.Each bearing comprises a first concave cylindrical half-bearing 48 and a second complementary concave cylindrical half-bearing 50.

Les deux premiers demi-paliers 48 sont formés à l'extrémité d'une partie en forme de plaque 52 qui s'étend en saillie depuis la face interne 13 du nez de démarreur 11.The first two half-bearings 48 are formed at the end of a plate-shaped part 52 which projects from the internal face 13 of the starter nose 11.

La plaque 52 est réalisée venue de moulage avec le nez de démarreur 11 et s'étend dans un plan contenant l'axe X-X et qui est parallèle aux axes de l'actionneur électromagnétique 12 et du moteur électrique 14.The plate 52 is produced by molding with the starter nose 11 and extends in a plane containing the axis X-X and which is parallel to the axes of the electromagnetic actuator 12 and the electric motor 14.

La plaque 52 est positionnée de manière que l'axe X-X soit situé dans un plan horizontal, en considérant la figure 1 qui s'étend entre les carters 18 et 24 de l'actionneur électromagnétique 12 du moteur électrique 14.The plate 52 is positioned so that the axis X-X is located in a horizontal plane, considering FIG. 1 which extends between the casings 18 and 24 of the electromagnetic actuator 12 of the electric motor 14.

La partie avant de la plaque 52 comporte un dégagement central 54 qui lui confère une forme de fourche de manière à permettre les mouvements de pivotement de la partie centrale en vis-à-vis 56 du levier d'actionnement 32.The front part of the plate 52 has a central clearance 54 which gives it a fork shape so as to allow the pivotal movements of the central part opposite 56 of the actuating lever 32.

Les deux seconds demi-paliers cylindriques concaves 50 sont formés à l'extrémité de la portion avant en forme de plaque rectangulaire 58 d'une cale de montage 60 dont la partie arrière 62 est montée entre les parties avant 16 et 22 des carters 18 et 24 de l'actionneur 12 et du moteur 14.The two second concave cylindrical half-bearings 50 are formed at the end of the front portion in the form of a rectangular plate 58 of a mounting block 60, the rear part 62 of which is mounted between the front parts 16 and 22 of the housings 18 and 24 of the actuator 12 and of the motor 14.

La cale 60 est une pièce moulée en matière plastique dont la partie avant est une plaque horizontale qui s'étend dans un plan qui, en position montée comme cela est illustré à la figure 1, est confondu avec le plan de la partie en forme de plaque 52 du nez de démarreur 11.The wedge 60 is a plastic molded part, the front part of which is a horizontal plate which extends in a plane which, in the assembled position as illustrated in FIG. 1, coincides with the plane of the part in the form of starter nose plate 52 11.

La partie avant 58 comporte également un dégagement 64 pour permettre les mouvements de pivotement de la face correspondante 66 de la partie centrale du corps du levier d'actionnement 32 autour des tronçons 46 de l'axe d'articulation.The front part 58 also includes a clearance 64 to allow the pivoting movements of the corresponding face 66 of the central part of the body of the actuating lever 32 around the sections 46 of the articulation axis.

La partie arrière 62 de la cale de montage 60 est une plaque verticale qui s'étend dans un plan perpendiculaire à celui de la partie avant 58 et qui comporte une première surface cylindrique concave 66 qui est complémentaire de la surface cylindrique convexe de la partie avant 16 du carter 18 de l'actionneur électromagnétique 12.The rear part 62 of the mounting block 60 is a vertical plate which extends in a plane perpendicular to that of the front part 58 and which comprises a first concave cylindrical surface 66 which is complementary to the convex cylindrical surface of the front part 16 of the casing 18 of the electromagnetic actuator 12.

La partie arrière 62 comporte une seconde surface cylindrique concave d'appui 68 qui est complémentaire de la surface cylindrique externe convexe de la partie avant 22 du carter 24 du moteur électrique 14.The rear part 62 comprises a second concave cylindrical support surface 68 which is complementary to the convex external cylindrical surface of the front part 22 of the casing 24 of the electric motor 14.

La partie arrière en forme de plaque 62 est ainsi emboîtée entre les deux parties avant cylindriques de l'actionneur électromagnétique 12 et du moteur électrique 14.The plate-shaped rear part 62 is thus fitted between the two cylindrical front parts of the electromagnetic actuator 12 and of the electric motor 14.

Afin de la maintenir en position entre ces deux éléments, elle comporte, à sa partie inférieure, un doigt d'indexation et de montage 70 qui s'étend radialement vers le bas en saillie depuis la surface d'appui cylindrique concave 68 pour être reçu dans un évidement complémentaire formé dans la partie avant 22 du carter 24.In order to keep it in position between these two elements, it comprises, at its lower part, an indexing and mounting finger 70 which extends radially downwards projecting from the concave cylindrical bearing surface 68 to be received in a complementary recess formed in the front part 22 of the casing 24.

La cale est ainsi positionnée et est maintenue en position entre les deux éléments principaux du démarreur.The shim is thus positioned and is held in position between the two main elements of the starter.

Le montage du levier d'actionnement 32 est donc particulièrement simple car il est mis en appui sur les deux seconds demi-paliers cylindriques concaves 50 de la cale de montage 60, les paliers d'articulation proprement dits étant reconstitués lors de l'opération d'assemblage finale du nez de démarreur 11.The mounting of the actuation lever 32 is therefore particularly simple since it is supported on the two second concave cylindrical half-bearings 50 of the mounting shim 60, the articulation bearings proper being reconstituted during the operation d final assembly of the starter nose 11.

Les coûts de fabrication des moyens d'articulation sont particulièrement réduits dans la mesure où les premiers demi-paliers 48 sont réalisés venus de matière lors du moulage du nez de démarreur 11 et dans la mesure où les seconds demi-paliers 50 sont formés à l'extrémité d'une cale en matière plastique 60.The manufacturing costs of the articulation means are particularly reduced insofar as the first half-bearings 48 are produced integrally during the molding of the starter nose 11 and insofar as the second half-bearings 50 are formed at the end of a plastic block 60.

Les opérations de montage sont particulièrement simplifiés car elles ne nécessitent aucune opération d'introduction d'un axe selon sa direction générale ni de déformation ou d'écartement de pièce pour introduire l'axe.The mounting operations are particularly simplified because they do not require any operation of introducing an axis in its general direction or of deformation or spacing of the workpiece to introduce the axis.
