Description

Machine électrique tournante destinée à être montée sur un véhicule automobile Rotating electric machine for mounting on a motor vehicle
La présente invention concerne notamment une machine électrique tournante destinée à être montée sur un véhicule automobile.The present invention relates in particular to a rotating electrical machine intended to be mounted on a motor vehicle.
La machine est notamment un démarreur, en particulier un démarreur du type à pignon sortant.The machine is in particular a starter, in particular an outgoing gear type starter.
Le brevet US 6 169 333 décrit un exemple d'un tel démarreur à pignon sortant. Ce démarreur comporte un arbre à une extrémité duquel est fixé un pignon. Celui- ci s'étend à l'extérieur du carter du démarreur. Le carter comporte à l'arrière un palier définissant une cavité pour recevoir une portion arrière de l'arbre.US Pat. No. 6,169,333 describes an example of such an outgoing starter motor. This starter has a shaft at one end of which is fixed a pinion. This extends outside the starter housing. The housing has at the rear a bearing defining a cavity for receiving a rear portion of the shaft.
Il est par ailleurs connu de réaliser un calage axial de l'arbre à l'aide d'une pièce de maintien telle qu'un circlips.It is also known to perform an axial wedging of the shaft with the aid of a holding piece such as a circlip.
L'invention vise notamment à simplifier l'assemblage d'une machine électrique tournante, notamment un démarreur, au niveau d'un arbre rotatif.The invention aims in particular to simplify the assembly of a rotating electrical machine, including a starter, at a rotary shaft.
L'invention a ainsi pour objet une machine électrique tournante destinée à être montée sur un véhicule automobile, comportant :The invention thus relates to a rotating electrical machine intended to be mounted on a motor vehicle, comprising:
- un carter pourvu d'une ouverture,- a housing provided with an opening,
- un arbre rotatif comportant une portion arrière notamment s'étendant à travers l'ouverture du carter,a rotary shaft including a rear portion extending in particular through the opening of the casing,
- un capot agencé pour obturer sensiblement l'ouverture du carter, la machine étant caractérisée par le fait que le capot est porté par ladite portion arrière de l'arbre.- A cover arranged to substantially close the opening of the housing, the machine being characterized in that the cover is carried by said rear portion of the shaft.
L'invention permet notamment de simplifier l'assemblage de la machine car le capot peut être mis en place simplement sur l'arbre, sans fixation sur un palier de la machine, par exemple par vissage.The invention makes it possible in particular to simplify the assembly of the machine because the cover can be put in place simply on the shaft, without fixing on a bearing of the machine, for example by screwing.
Le capot sert à obturer l'ouverture du carter, de manière parfaitement étanche ou non. Le capot peut être porté par l'arbre de manière à ce que ce capot tourne avec l'arbre lorsque celui-ci est en rotation. En variante, le capot ne tourne pas avec l'arbre.The cover is used to close the opening of the housing, perfectly sealed or not. The hood can be carried by the shaft so that the cover rotates with the shaft when it is rotating. Alternatively, the hood does not rotate with the shaft.
Dans un exemple de mise en oeuvre de l'invention, le capot peut s'étendre entièrement à l'extérieur du carter.In an exemplary implementation of the invention, the cover can extend entirely outside the housing.
Le cas échéant, le capot peut être dépourvu de contact radial avec le carter.If necessary, the cover may be devoid of radial contact with the housing.
De préférence, le maintien du capot sur le carter nécessite la présence de la portion arrière de l'arbre, c'est-à-dire sans cette portion arrière de l'arbre le capot ne peut pas être retenu contre le carter. Avantageusement la machine comporte un organe de calage agencé pour être fixé sur la portion arrière de l'arbre et venir en appui sur le carter de manière à s'opposer à un déplacement axial de l'arbre vers l'avant de la machine.Preferably, maintaining the hood on the housing requires the presence of the rear portion of the shaft, that is to say without this rear portion of the shaft hood can not be retained against the housing. Advantageously, the machine comprises a wedging member arranged to be fixed on the rear portion of the shaft and bear against the housing so as to oppose an axial displacement of the shaft towards the front of the machine.
L'organe de calage est notamment agencé pour pouvoir être placé sur l'arbre sans être déformé élastiquement, à la différence par exemple d'un circlips. De préférence, l'organe de calage comporte un orifice agencé pour permettre son introduction sur la portion arrière de l'arbre et son maintien sur cette portion.The wedging member is in particular arranged to be placed on the shaft without being elastically deformed, unlike for example a circlip. Preferably, the wedging member comprises an orifice arranged to allow its introduction on the rear portion of the shaft and its maintenance on this portion.
La portion arrière de l'arbre comporte avantageusement une rainure et l'orifice de l'organe de calage comporte une première région agencée pour permettre le passage de la portion arrière de l'arbre, et une deuxième région adjacente à la première et agencée pour permettre d'engager une portion de l'organe de calage adjacente à cette deuxième région dans la rainure de la portion arrière de l'arbre de manière à assurer le maintien de l'organe de calage sur l'arbre.The rear portion of the shaft advantageously comprises a groove and the orifice of the wedging member comprises a first region arranged to allow the passage of the rear portion of the shaft, and a second region adjacent to the first and arranged to allow to engage a portion of the wedging member adjacent to the second region in the groove of the rear portion of the shaft so as to maintain the wedging member on the shaft.
Le positionnement de l'organe de calage sur l'arbre est effectué en insérant d'abord l'arbre à travers la première région de l'orifice puis en translatant l'organe de calage de manière à amener la portion arrière de l'arbre dans la deuxième région de l'orifice.The positioning of the wedging member on the shaft is performed by first inserting the shaft through the first region of the orifice and then translating the wedging member so as to bring the rear portion of the shaft in the second region of the orifice.
Dans un exemple de mise en oeuvre de l'invention, l'une au moins des première et deuxième régions de l'orifice présente un pourtour sensiblement en arc de cercle. La superficie de la première région est supérieure à celle de la deuxième. En variante, l'une au moins de ces régions présente un pourtour ayant une forme différente d'un arc de cercle, ayant par exemple une forme en ovale ou en portion de polygone.In an exemplary implementation of the invention, at least one of the first and second regions of the orifice has a periphery substantially in an arc. The area of the first region is greater than that of the second. As a variant, at least one of these regions has a periphery having a shape different from an arc of circle, having for example an oval or polygonal portion shape.
Avantageusement l'organe de calage présente un pourtour extérieur sensiblement circulaire, et la première région de l'orifice est excentrée par rapport à un centre de l'organe de calage.Advantageously, the wedging member has a substantially circular outer periphery, and the first region of the orifice is eccentric with respect to a center of the wedging member.
En variante, l'organe de calage est un circlips ayant la forme d'une bague fendue, agencé pour être mis en place sur l'arbre.Alternatively, the wedging member is a circlip in the form of a split ring, arranged to be placed on the shaft.
Dans un exemple de mise en oeuvre de l'invention, le capot est agencé pour être fixé, notamment par encliquetage, sur l'organe de calage, notamment via au moins une portion périphérique de l'organe de calage.In an exemplary implementation of the invention, the cover is arranged to be fixed, in particular by snapping, on the wedging member, in particular via at least one peripheral portion of the wedging member.
L'assemblage du capot avec l'organe de calage peut ainsi être relativement simple.The assembly of the cover with the wedging member can thus be relatively simple.
Le capot n'est pas directement fixé sur la portion arrière de l'arbre, mais par l'intermédiaire de l'organe de calage.The cover is not directly attached to the rear portion of the shaft, but via the wedging member.
L'organe de calage et le capot forment un ensemble permettant à la fois un calage axial de l'arbre et l'obturation de l'ouverture arrière du carter.The wedging member and the cover form an assembly allowing both an axial setting of the shaft and the closing of the rear opening of the housing.
Dans un exemple de mise en oeuvre de l'invention, l'organe de calage comporte une portion périphérique formant une collerette, notamment annulaire, et le capot comporte sur sa surface intérieure une gorge, notamment annulaire, permettant d'y engager la collerette de l'organe de calage lorsque le capot est fixé, notamment par encliquetage, sur l'organe de calage.In an exemplary implementation of the invention, the wedging member comprises a peripheral portion forming a flange, in particular an annular flange, and the cover has on its inner surface a groove, in particular an annular groove, making it possible to engage the flange of the flange. the wedging member when the cover is fixed, in particular by snapping, on the wedging member.
La collerette s'étend par exemple dans un plan décalé suivant une translation, par rapport à un plan d'une portion centrale de l'organe de calage. Avantageusement, le capot comporte sur sa surface intérieure au moins une portion en relief, notamment une jupe annulaire, agencée pour s'engager sur la portion arrière de l'arbre lorsque le capot est fixé sur l'organe de calage.The flange extends for example in a plane offset in a translation, relative to a plane of a central portion of the wedging member. Advantageously, the cover has on its inner surface at least one raised portion, in particular an annular skirt, arranged to engage the rear portion of the shaft when the cap is fixed on the wedging member.
Cette portion en relief, notamment la jupe annulaire, permet d'empêcher une translation accidentelle de l'organe de calage dans le sens de son désengagement de l'arbre. Autrement dit, la mise en place du capot sur l'organe de calage permet le verrouillage de celui-ci sur l'arbre.This portion in relief, in particular the annular skirt, prevents accidental translation of the wedging member in the direction of disengagement from the shaft. In other words, the introduction of the cover on the wedging member allows the locking of the latter on the shaft.
Dans un exemple de mise en oeuvre de l'invention, la fixation de l'organe de calage et du capot sur l'arbre est indémontable. L'organe de calage est par exemple réalisé en métal traité et le capot en matière plastique, chargé ou non, par exemple en polyamide (PA).In an exemplary implementation of the invention, the fixing of the wedging member and the cover on the shaft is unmountable. The wedging member is for example made of treated metal and the plastic cover, loaded or not, for example polyamide (PA).
Dans un exemple de mise en oeuvre de l'invention, la machine est un démarreur de véhicule automobile, notamment du type comportant un organe d'entraînement tel qu'un pignon, s'étendant à l'avant en dehors d'un carter du démarreur.In an exemplary implementation of the invention, the machine is a starter motor vehicle, including the type comprising a drive member such as a pinion, extending to the front outside a housing of the starter.
L'invention a encore pour objet un organe de calage agencé pour coopérer avec une portion arrière d'un arbre rotatif d'une machine électrique tournante, notamment une machine telle que définie ci-dessus, la portion de l'arbre comportant une rainure, l'organe de calage étant caractérisé par le fait qu'il comprend un orifice comportant une première région agencée pour permettre le passage de la portion arrière de l'arbre, et une deuxième région adjacente à la première et agencée pour permettre d'engager une portion de l'organe de calage adjacente à cette deuxième région dans la rainure de la portion arrière de l'arbre de manière à assurer le maintien de l'organe de calage sur l'arbre. L'invention a également pour objet une machine électrique tournante destinée à être montée sur un véhicule automobile, comportant :The invention also relates to a wedging member arranged to cooperate with a rear portion of a rotary shaft of a rotating electrical machine, in particular a machine as defined above, the portion of the shaft having a groove, the wedging member being characterized in that it comprises an orifice having a first region arranged to allow the passage of the rear portion of the shaft, and a second region adjacent to the first and arranged to allow to engage a portion of the wedging member adjacent to this second region in the groove of the rear portion of the shaft so as to maintain the wedging member on the shaft. The invention also relates to a rotating electrical machine intended to be mounted on a motor vehicle, comprising:

- la figure 7 représente, schématiquement et partiellement, en coupe, le démarreur de la figure 6.- Figure 7 shows schematically and partially in section, the starter of Figure 6.
On a représenté sur la figure 1 différents éléments d'une machine électrique tournante 1 formée, dans l'exemple considéré, par un démarreur de véhicule automobile.FIG. 1 shows various elements of a rotary electric machine 1 formed, in this example, by a starter of a motor vehicle.
Ce démarreur est notamment un démarreur de type à pignon sortant, à savoir comportant à l'avant un pignon s'étendant en dehors du carter du démarreur et servant à entraîner un moteur thermique du véhicule. Le démarreur 1 représenté sur la figure 1 comporte un carter 2 pourvu d'une ouverture arrière 3, et un arbre rotatif 4 d'axe X comprenant une portion arrière 5 s'étendant à travers l'ouverture 3.This starter is in particular an outgoing gear type starter, namely having at the front a pinion extending outside the starter housing and serving to drive a heat engine of the vehicle. The starter 1 shown in FIG. 1 comprises a housing 2 provided with a rear opening 3, and a rotary shaft 4 with an X axis comprising a rear portion 5 extending through the opening 3.
Le carter 2 comporte une face arrière 7, sensiblement circulaire, comprenant une portion centrale surélevée 8, de forme circulaire, sur laquelle débouche l'ouverture 3. En variante, la face arrière 7 peut être dépourvue de portion centrale surélevée 8.The casing 2 comprises a substantially circular rear face 7, comprising a raised central portion 8 of circular shape, on which opens the opening 3. In a variant, the rear face 7 may have no raised central portion 8.
Une pièce 9 formant un passe-fil est fixée sur le carter 2 pour permettre le passage d'un élément conducteur 10 assurant la liaison électrique vers un contacteur, non représenté, appartenant à la machine 1.A part 9 forming a grommet is fixed on the housing 2 to allow the passage of a conductive element 10 providing the electrical connection to a contactor, not shown, belonging to the machine 1.
La face arrière 7 du carter 2 est réalisée par exemple en tôle métallique.The rear face 7 of the casing 2 is made for example of sheet metal.
Comme illustré sur la figure 5, le carter 2 comporte un retour 12 de forme cylindrique d'axe X s'étendant en direction de l'intérieur du carter 2, ce retour étant réalisé par exemple par emboutissage de la face arrière 7. En variante, le retour 12 peut être formé par une pièce rapportée sur le carter 2.As illustrated in FIG. 5, the casing 2 comprises a cylindrical X-shaped return 12 extending towards the inside of the casing 2, this return being made for example by stamping the rear face 7. As a variant , the return 12 may be formed by an insert on the housing 2.
Le retour 12 débouche sur l'ouverture 3 et l'arbre 4 s'engage à travers ce retour 12.The return 12 opens on the opening 3 and the shaft 4 engages through this return 12.
Un coussinet 14 est interposé entre l'arbre 4 et le retour 12.A pad 14 is interposed between the shaft 4 and the return 12.
Dans une variante non représentée, le coussinet peut être remplacé par une douille à aiguilles par exemple.In a variant not shown, the pad can be replaced by a needle socket for example.
Une rondelle de calage 15 est placée entre le coussinet 14 et un épaulement 17 de l'arbre 4.A wedging washer 15 is placed between the bush 14 and a shoulder 17 of the shaft 4.
La portion arrière 5 de l'arbre 4 comporte une rainure annulaire 20 s'étendant perpendiculairement à l'axe X. Dans l'exemple considéré, la rainure 20 comprend deux faces en regard sensiblement planes 21 , comme on peut le voir la figure 5.The rear portion 5 of the shaft 4 comprises an annular groove 20 extending perpendicularly to the axis X. In the example in question, the groove 20 comprises two substantially plane facing surfaces 21, as can be seen in FIG. .
Le calage axial de l'arbre 4 afin de l'empêcher de se déplacer vers l'avant du démarreur 1 est réalisé à l'aide d'un organe de calage 23 et un capot 24.The axial setting of the shaft 4 in order to prevent it from moving towards the front of the starter 1 is achieved by means of a wedging member 23 and a cover 24.
L'organe de calage 23 présente sensiblement une forme de disque et est traversé par un orifice 26 ayant un pourtour entièrement fermé. L'orifice 26 comporte une première région 28 agencée pour permettre le passage de la portion arrière 5 de l'arbre 4, et une deuxième région 29 adjacente à la première 28 et agencée pour permettre d'engager une portion 30 de l'organe de calage 23 adjacente à cette deuxième région 29 dans la rainure 20 de la portion arrière 5 de l'arbre 4 de manière à assurer le maintien de l'organe de calage 23 sur l'arbre 4.The wedging member 23 has substantially a disc shape and is traversed by an orifice 26 having a completely closed periphery. The orifice 26 comprises a first region 28 arranged to allow the passage of the rear portion 5 of the shaft 4, and a second region 29 adjacent to the first 28 and arranged to allow to engage a portion 30 of the wedging 23 adjacent to this second region 29 in the groove 20 of the rear portion 5 of the shaft 4 so as to maintain the wedging member 23 on the shaft 4.
Dans l'exemple illustré, les première 28 et deuxième 29 régions de l'orifice 26 présentent chacune un pourtour en arc de cercle, le diamètre de la première région 28 étant supérieur à celui de la deuxième région 29. Dans une variante non illustrée, l'une de ces régions 28 et 29 peut présenter un pourtour en portion de polygone.In the illustrated example, the first 28 and second 29 regions of the orifice 26 each have an arcuate circumference, the diameter of the first region 28 being greater than that of the second region 29. In a variant not illustrated, one of these regions 28 and 29 may have a perimeter polygon portion.
La deuxième région 29 est centrée sur l'axe X de l'arbre 4 tandis que la première région 28 est excentrée par rapport à cet axe X.The second region 29 is centered on the axis X of the shaft 4 while the first region 28 is eccentric with respect to this axis X.
Le positionnement de l'organe de calage 23 sur l'arbre 4 est effectué en insérant d'abord l'arbre 4 à travers la première région 28 de l'orifice 26 puis en translatant l'organe de calage 23 de manière à amener la portion arrière 5 de l'arbre 4 dans la deuxième région 29 de l'orifice 26, comme on peut le voir sur les figures 2 et 3. La portion 30 de l'organe de calage 23 est alors prise dans la rainure annulaire 20 de l'arbre. En variante, l'organe de calage 23 peut comporter un orifice présentant un pourtour ouvert, par exemple en forme de U.The positioning of the wedging member 23 on the shaft 4 is performed by first inserting the shaft 4 through the first region 28 of the orifice 26 and then translating the wedging member 23 so as to bring the rear portion 5 of the shaft 4 in the second region 29 of the orifice 26, as can be seen in Figures 2 and 3. The portion 30 of the wedging member 23 is then taken in the annular groove 20 of the tree. Alternatively, the wedging member 23 may comprise an orifice having an open periphery, for example U-shaped.
L'organe de calage 23 comporte une portion centrale 31 sur laquelle est réalisé l'orifice 26, et une portion périphérique 32 sous la forme d'une collerette s'étendant dans un plan décalé axialement par rapport au plan de la portion centrale 31. L'organe de calage 23 est réalisé par exemple en métal traité.The wedging member 23 comprises a central portion 31 on which the orifice 26 is made, and a peripheral portion 32 in the form of a flange extending in a plane axially offset with respect to the plane of the central portion 31. The wedging member 23 is made for example of treated metal.
Le capot 24 comporte une paroi de fond 35 sensiblement plane se prolongeant à sa périphérie par une paroi annulaire 36 perpendiculaire à la paroi de fond 35.The cover 24 has a substantially flat bottom wall 35 extending at its periphery by an annular wall 36 perpendicular to the bottom wall 35.
La paroi annulaire 36 comporte sur sa surface intérieure une gorge annulaire 37 agencée pour coopérer avec la collerette 32 de l'organe de calage en vue de permettre une fixation par encliquetage du capot 24 sur l'organe de calage 23. Comme illustré sur la figure 5, la paroi annulaire 36 comporte à son extrémité libre un bord intérieur biseauté 38 permettant de faciliter l'engagement de la collerette 32 dans la gorge 37 du capot 24.The annular wall 36 has on its inner surface an annular groove 37 arranged to cooperate with the flange 32 of the wedging member to allow snap-fastening of the cap 24 on the wedging member 23. As illustrated in FIG. 5, the annular wall 36 has at its free end a beveled inner edge 38 making it possible to facilitate the engagement of the flange 32 in the groove 37 of the cover 24.
Le capot 24 comporte en outre, au centre, une portion en relief sous la forme d'une jupe annulaire 39 coaxiale à la portion annulaire 36 et entourée par celle-ci.The cover 24 further comprises, in the center, a portion in relief in the form of an annular skirt 39 coaxial with the annular portion 36 and surrounded by it.
La hauteur de la jupe 39 est inférieure à celle de la paroi annulaire 36.The height of the skirt 39 is smaller than that of the annular wall 36.
Le capot 24 est réalisé par exemple par moulage d'une matière plastique telle que le PA.The cover 24 is made for example by molding a plastic material such as PA.
La jupe 39 s'engage sur la portion arrière 5 de l'arbre 4 lorsque le capot 24 est fixé sur l'organe de calage 23 de sorte que l'organe de calage 23 ne puisse pas se déplacer dans un plan transversal perpendiculaire à l'axe X.The skirt 39 engages the rear portion 5 of the shaft 4 when the cap 24 is fixed on the wedging member 23 so that the wedging member 23 can not move in a transverse plane perpendicular to the X axis.
Autrement dit, le capot 24 permet de verrouiller la mise en place de l'organe de calage 23 sur l'arbre 4.In other words, the cover 24 makes it possible to lock the establishment of the wedging member 23 on the shaft 4.
En fin de montage, le capot 24 masque l'organe de calage 23 et obture l'ouverture 3 du carter 2, comme on peut le voir sur la figure 4.At the end of assembly, the cover 24 masks the wedging member 23 and closes the opening 3 of the casing 2, as can be seen in FIG. 4.
Le capot 24 peut éventuellement permettre une obturation étanche de l'ouverture 3.The cover 24 may optionally allow sealing of the opening 3.
L'un au moins de l'organe de calage 23 et du capot 24 peut éventuellement tourner avec l'arbre 4 lorsque la force de friction entre cet ensemble et l'arbre 4 est suffisante.At least one of the wedging member 23 and the cover 24 may optionally rotate with the shaft 4 when the frictional force between this assembly and the shaft 4 is sufficient.
En variante, l'un au moins de l'organe de calage 23 et du capot 24 peut être en appui avec un frottement suffisant sur la face 7 de manière à ce que ce ou ces éléments 23 et/ou 24 ne tournent pas avec l'arbre 4.As a variant, at least one of the wedging member 23 and the cover 24 may be in abutment with sufficient friction on the face 7 so that this or these elements 23 and / or 24 do not rotate with the tree 4.
Bien entendu, l'invention n'est pas limitée à l'exemple de mise en œuvre qui vient d'être décrit.Of course, the invention is not limited to the implementation example which has just been described.
La jupe annulaire 39 du capot 24 peut, le cas échéant, être remplacée par exemple par une pluralité de dents disposées suivant une surface cylindrique.The annular skirt 39 of the cover 24 may, if necessary, be replaced for example by a plurality of teeth arranged along a cylindrical surface.
La paroi annulaire 36 quant à elle peut être remplacée, si on le souhaite, par une pluralité de pattes d'encliquetage. L'organe de calage 23 peut comporter, à la place de la collerette 32, une pluralité de pattes pouvant s'engager dans la gorge 37 du capot 24.The annular wall 36 in turn can be replaced, if desired, by a plurality of latching lugs. The wedging member 23 may comprise, in place of the flange 32, a plurality of tabs engageable in the groove 37 of the cover 24.
Dans certaines applications, il est possible de prévoir une fixation directe du capot 24 sur l'arbre, sans utilisation de l'organe de calage 23. A cet effet, la jupe 39 du capot 24 peut comporter par exemple des reliefs permettant d'encliqueter cette jupe 39 sur la rainure 20 de l'arbre.In some applications, it is possible to provide a direct attachment of the cover 24 on the shaft, without the use of the wedging member 23. For this purpose, the skirt 39 of the cover 24 may comprise for example reliefs for snapping this skirt 39 on the groove 20 of the shaft.
On a représenté sur les figures 6 et 7 un démarreur 40 selon un autre exemple de mise en œuvre de l'invention.FIGS. 6 and 7 show a starter 40 according to another embodiment of the invention.
Ce démarreur 40 comporte un organe de calage 23 comme décrit ci-dessus, fixé sur l'arbre 4.This starter 40 comprises a wedging member 23 as described above, fixed on the shaft 4.
A la différence de ce qui est décrit plus haut, le démarreur 40 comprend un capot 41 fixé sur le carter 2, et non porté par l'arbre 4.Unlike what is described above, the starter 40 comprises a cover 41 fixed to the casing 2, and not worn by the shaft 4.
Ce capot 41 comporte une coupelle 42 agencée pour recouvrir l'organe de calage 23 lorsque ce capot 41 est fixé sur le carter 2. Le capot 41 comprend en outre deux pattes de fixation 44 s'étendant de part et d'autre de la coupelle 42 et pourvues chacune d'un orifice 48 pour permettre le passage d'un tirant 45 du démarreur, en vue de fixer le capot 41 sur la face arrière 7 du carter 2.This cover 41 comprises a cup 42 arranged to cover the wedging member 23 when the cover 41 is fixed on the housing 2. The cover 41 further comprises two fastening tabs 44 extending on either side of the cup 42 and each provided with an orifice 48 to allow the passage of a tie rod 45 of the starter, in order to fix the cover 41 on the rear face 7 of the housing 2.
En variante, le capot 41 est fixé sur le carter 2 à l'aide de vis. L'organe de calage 23 logé à l'intérieur de la coupelle 42 est bloqué en translation, ce qui assure son maintien sur l'arbre 4.Alternatively, the cover 41 is fixed on the housing 2 with screws. The wedging member 23 housed inside the cup 42 is locked in translation, which ensures its maintenance on the shaft 4.
Le capot 41 permet une obturation étanche de l'ouverture 3 du carter 2, par exemple grâce à un joint, notamment un joint papier, prévu sur le capot 41 pour venir en appui contre le carter 2. The cover 41 allows sealing of the opening 3 of the housing 2, for example by means of a seal, in particular a paper seal, provided on the cover 41 to bear against the housing 2.
