Description

Support accessoire faisant office de palier relais. La présente inventionAccessory support acting as relay bearing. The present invention

se rapporte au domaine des supports de fixation d'accessoires sur les moteurs, et plus particulièrement à un produit qui assure le positionnement, à proximité d'un moteur à transmission latérale, d'un ou plusieurs éléments dont un palier relais pour un roulement de l'arbre de transmission. II est connu d'utiliser sur un moteur une pièce différente pour la fixation de chaque fonction à réaliser comme, par exemple, un alternateur, une pompe de direction assistée, un compresseur de climatisation. Plusieurs to accessoires à fonctions différentes sont ainsi positionnés ensemble, sur une même face du moteur dite accessoire, par des supports auxquels ils sont fixés indépendamment entre eux. Cependant, cette situation conduit à une multiplication du nombre de pièces support à usiner puis à positionner sur le moteur, ce qui présente comme désavantage de rallonger la durée du is montage de tous ces éléments autour du moteur. Le brevet EP 1 415 847 Al propose un palier relais pouvant être fixé sur un moteur (page 3, col 4, ligne 39 à 42) ou faisant partie intégrante d'une pièce de moteur (page 3, col 4, ligne 42 à 44) ou d'une pièce d'assemblage de moteur (page 3, col 4, ligne 46 et 47). Certes, l'intégration d'un palier 20 relais dans la structure du moteur permet de diminuer le nombre de pièces destinées à y être fixées mais cette solution ne résout en rien la problématique d'optimisation du temps de montage. La présente invention a pour but de limiter le nombre de pièces à usiner avant leur montage sur un moteur. 25 Ce but est atteint par un élément de support pour accessoires qui fait partie d'un ensemble multifonction pour moteur à transmission latérale et destiné à être monté sur la face échappement du carter d'un moteur pourvue de points de fixation adaptés à l'élément, caractérisé en ce qu'il comprend une pièce monobloc incluant : - une première partie munie de moyens de fixation pour positionner au moins un accessoire dans la périphérie du moteur - et une seconde partie qui intègre dans sa structure un palier relais composé d'un bras de support et d'un élément de maintien qui forment un logement ouvrable destiné après fermeture à encercler le roulement d'un arbre de transmission. L'intégration d'un palier relais dans la structure d'un support de fixation pour un ou plusieurs accessoires permet de réduire le nombre de pièces à usiner et diminue le nombre de point de fixation sur le moteur. io Le palier relais, qui supporte le roulement et l'arbre de transmission, est monté, de préférence, perpendiculairement à son support, de façon qu'après fixation du support au carter l'axe de rotation du roulement soit parallèle à celui du vilebrequin. Selon une particularité de l'invention, l'élément de maintien ouvrable 15 est articulé autour d'un pivot situé dans le tiers inférieur du diamètre du roulement et mobile dans un plan perpendiculaire à l'axe de l'arbre de transmission. Un autre but de l'invention est de proposer un produit et un procédé qui répondent au problème de l'optimisation du temps de montage auquel 20 l'art antérieur ne répond pas. Ce but est atteint grâce à un élément de support pour accessoires, objet de l'invention, caractérisé en ce que les points de fixations situés sur sa structure et destinés à permettre son positionnement sur le carter du moteur sont placés de telle façon qu'ils demeurent toujours accessibles lorsqu'un ou 25 plusieurs accessoires sont déjà fixés sur la première partie du support. Cette caractéristique permet le positionnement de différents accessoires entre eux et avec le palier relais indépendamment du montage sur le moteur. Un autre but de l'invention est de proposer un procédé qui permette 30 d'optimiser le temps de montage d'au moins un accessoire et d'un roulement d'arbre à transmission dans la périphérie du moteur.  relates to the field of attachment brackets of accessories on the engines, and more particularly to a product which ensures the positioning, near a motor with lateral transmission, of one or more elements including a relay bearing for a rolling bearing. the drive shaft. It is known to use on a motor a different part for the attachment of each function to be performed such as, for example, an alternator, a power steering pump, an air conditioning compressor. Several accessories to different functions are thus positioned together, on the same face of the so-called accessory motor, by supports to which they are attached independently of each other. However, this situation leads to a multiplication of the number of support pieces to be machined and then to position on the engine, which has the disadvantage of extending the duration of assembly of all these elements around the engine. Patent EP 1 415 847 A1 proposes a relay bearing which can be fixed on a motor (page 3, col 4, line 39 to 42) or which is an integral part of a motor part (page 3, col 4, line 42 to 44 ) or an engine assembly part (page 3, col 4, line 46 and 47). Admittedly, the integration of a relay bearing 20 in the engine structure reduces the number of parts to be fixed but this solution does not solve the problem of optimizing the assembly time. The present invention aims to limit the number of workpieces before mounting on a motor. This object is achieved by an accessory support member which is part of a multi-function unit for a side-drive motor and intended to be mounted on the exhaust face of the engine casing provided with fixing points adapted to the element. , characterized in that it comprises a single piece including: - a first part provided with fastening means for positioning at least one accessory in the periphery of the engine - and a second part which incorporates in its structure a relay bearing composed of a support arm and a holding member which form an openable housing after closure to encircle the bearing of a transmission shaft. Integrating a relay bearing into the structure of a mounting bracket for one or more accessories reduces the number of workpieces and reduces the number of attachment points on the motor. The relay bearing, which supports the bearing and the transmission shaft, is mounted, preferably, perpendicular to its support, so that after attachment of the support to the housing the axis of rotation of the bearing is parallel to that of the crankshaft. . According to a feature of the invention, the openable holding element 15 is articulated about a pivot located in the lower third of the diameter of the bearing and movable in a plane perpendicular to the axis of the transmission shaft. Another object of the invention is to provide a product and a method which respond to the problem of optimizing the mounting time at which the prior art does not respond. This object is achieved by means of a support element for accessories, object of the invention, characterized in that the fixing points located on its structure and intended to allow its positioning on the motor housing are placed in such a way that they always remain accessible when one or more accessories are already attached to the first part of the support. This feature allows the positioning of various accessories between them and with the relay bearing independently of the mounting on the motor. Another object of the invention is to provide a method which makes it possible to optimize the mounting time of at least one accessory and a transmission shaft bearing in the periphery of the motor.

Ce but est atteint par un procédé de montage caractérisé en ce qu'il comprend : - la fixation du support pour accessoires sur le carter du moteur au niveau de points de fixation situés sur le moteur, - la fixation d'au moins un accessoire sur l'élément de support monobloc au niveau de l'interface accessoire du support, et/ou - le positionnement d'un roulement d'arbre de transmission dans le palier relais intégré au support. Selon une particularité de l'invention, le procédé de montage est io caractérisé en ce que l'étape de fixation du support sur le carter du moteur succède soit à une étape de fixation d'un accessoire au support, soit à l'étape de positionnement du roulement de l'arbre de transmission dans le palier relais intégré au support. Le produit de ce procédé est un ensemble multifonction pour moteur 15 à transmission latérale caractérisé en ce qu'il comporte au moins un accessoire, un roulement d'un arbre de transmission et une pièce monobloc à interfaces multiples qui, elle-même, comporte une interface avec le carter moteur constituée d'alésages de moyens de positionnement et de moyens de fixation, une interface avec l'accessoire et un bras de support pour palier 20 relais monté sur le support de façon qu'après fixation du support au carter du moteur l'axe de rotation du roulement soit parallèle à celui du vilebrequin. Cet ensemble multifonction, constitué d'au moins un accessoire, d'un roulement d'arbre de transmission et de l'élément de support, est ainsi assemblé avant que le moteur ne soit déjà monté, ou bien concomitamment 25 au montage du moteur, pour être ensuite monté comme une seule pièce sur le carter du moteur. Un avantage de l'invention est de passer d'un positionnement connu et habituel des accessoires sur la face accessoire du moteur à transmission latérale au positionnement d'au moins un de ces accessoires sur la face 30 échappement du moteur ce qui entraine un gain d'espace sur la face accessoire du moteur.  This object is achieved by a mounting method characterized in that it comprises: - fixing the accessory support on the motor housing at attachment points located on the engine, - fixing at least one accessory on the one-piece support element at the accessory interface of the support, and / or - the positioning of a transmission shaft bearing in the relay bearing integrated in the support. According to one particularity of the invention, the mounting method is characterized in that the step of fixing the support on the motor housing succeeds either to a step of fixing an accessory to the support, or to the step of positioning of the drive shaft bearing in the relay bearing integrated in the support. The product of this method is a multi-function unit for a side-transmission engine characterized in that it comprises at least one accessory, a bearing of a transmission shaft and a multi-interface monoblock component which itself has a interface with the crankcase consisting of bores of positioning means and fixing means, an interface with the accessory and a support arm for bearing 20 relay mounted on the support so that after fixing the support to the motor housing the axis of rotation of the bearing is parallel to that of the crankshaft. This multifunction assembly, consisting of at least one accessory, a transmission shaft bearing and the support element, is thus assembled before the engine is already mounted, or concomitantly 25 to the mounting of the engine, to then be mounted as one piece on the motor housing. An advantage of the invention is to go from a known and usual positioning of the accessories on the accessory side of the engine with lateral transmission to the positioning of at least one of these accessories on the exhaust face 30 of the engine which leads to a gain of space on the accessory side of the engine.

L'invention, avec ses caractéristiques et avantages, ressortira plus clairement à la lecture de la description ci-après faite en référence aux dessins annexés dans lesquels : - la figure 1 représente de façon schématique une vue en 5 perspective d'un support de fixation, objet de l'invention, intégrant un palier relais dans sa structure. - la figure 2 représente de façon schématique une vue en perspective d'un support de fixation, objet de l'invention, fixé sur le carter cylindres d'un moteur pour d'une part positionner un alternateur et d'autre io part maintenir le roulement de l'arbre de transmission avec le palier relais intégré dans sa structure. Le support de fixation de l'invention comprend trois parties. Une première partie, présentant au moins un moyen de fixation (6), positionne le support de fixation sur le carter cylindres du moteur (13). Une seconde 15 partie, comprenant au moins un moyen de fixation adéquat (7), supporte au moins un accessoire (9) sur le moteur (13), préférentiellement sur le carter cylindres. Une troisième partie, définie par un bras de support (3) pour le palier relais (17) intégré dans sa structure, assure le maintien d'un roulement (12) de l'arbre de transmission (18).  The invention, with its features and advantages, will emerge more clearly from a reading of the following description given with reference to the appended drawings in which: FIG. 1 schematically represents a perspective view of a mounting support object of the invention, incorporating a relay bearing in its structure. FIG. 2 schematically represents a perspective view of a fastening support, object of the invention, fixed on the crankcase of an engine in order, on the one hand, to position an alternator and, on the other hand, to maintain the transmission shaft bearing with integrated relay bearing in its structure. The fastening support of the invention comprises three parts. A first part, having at least one fastening means (6), positions the mounting bracket on the cylinder block of the engine (13). A second part, comprising at least one suitable fixing means (7), supports at least one accessory (9) on the motor (13), preferably on the cylinder block. A third part, defined by a support arm (3) for the relay bearing (17) integrated in its structure, maintains a bearing (12) of the transmission shaft (18).

20 Le support de fixation, objet de l'invention, est une pièce monobloc multifonction. La structure du support présente une face (1) de préférence sensiblement plane qui peut avoir une ou plusieurs saillies (5) sur sa face opposée en contact avec le moteur (13). Ces saillies (5) sont orientées de façon adéquate pour permettre le positionnement sur le moteur (13) de 25 l'ensemble multifonction composé du support, du roulement (12) et de l'accessoire (9). Les saillies (5), placées dans le prolongement des perçages (4) du support, permettent de maintenir le corps du support à distance du moteur (13). Ainsi, le moyen de fixation (6), de type tige, goujon ou clavette, traverse le support dans un alésage (4) selon un axe perpendiculaire au plan 30 de la pièce, continue à l'intérieure d'une saillie (5) et vient s'enfoncer dans un alésage taraudé du carter cylindres du moteur (13) situé en regard du point de fixation du support. Le placement de ces points de fixation sur la pièce multifonction, des alésages (4) et des saillies (5), est réalisé de telle sorte qu'ils soient toujours accessibles, même lorsque l'accessoire (9) est fixé sur le support. Le support de fixation assure le positionnement en périphérie du moteur (13) d'au moins un accessoire (9) en utilisant un ou plusieurs moyens de fixation (10). Ces moyens peuvent être des vis ou des tiges filetées. La surface plane du support peut alors présenter au moins une saillie (7) traversée par un alésage taraudé (8). Des saillies (11) semblables, situées sur l'accessoire (9) supporté, viennent enserrer la saillie (7) située sur le support de fixation en y alignant leurs alésages respectifs. Le moyen de fixation fileté (10) pénètre alors les alésages taraudés (8) successifs de l'accessoire et du support, alignés selon un axe parallèle au plan du support de fixation. Le placement de ces saillies (7) est réalisé de telle sorte que les points de fixation du support sur le carter du moteur (13), c'est à dire les alésages (4), les moyens de positionnement (5) et les moyens de fixation (6) demeurent accessibles lorsque le ou les accessoires (9) sont positionnés sur la pièce multifonction. Le support de fixation positionné sur le moteur (13) intègre dans sa structure un palier relais (17), tel que présenté sur les figures 1 et 2, qui est réalisé préférentiellement selon le modèle proposé par le brevet EP 1 415 847 Al. Il s'agit d'un bras de support (3) intégré au support de fixation, supporté, si nécessaire, par un prolongement (2) pouvant être incliné ou disposé sensiblement dans le même plan que le reste de la pièce qui le supporte. Ce bras de support (3) est placé préférentiellement dans un plan sensiblement perpendiculaire au plan de son support (2), de sorte qu'après fixation du support au carter du moteur (13), l'axe de rotation du roulement (12) soit parallèle à celui du vilebrequin. Ce bras (3) entoure le roulement (12) de l'arbre de transmission (18) au niveau de sa partie supérieure et est associé à un élément de maintien (14) qui entoure l'arbre de transmission au niveau de sa partie inférieure. Cet élément de maintien (14) est ouvrable. Il est articulé selon un plan perpendiculaire à l'axe de l'arbre de transmission (18), autour d'un pivot (15) situé dans le tiers inférieur du diamètre du roulement (12). Un second point de fixation permet de fixer de façon réversible l'élément de maintien (14) à l'extrémité du bras de support (3) avec un moyen de fixation (16). Le bras de support (3) et l'élément de maintien (14) forment ainsi un palier relais (17) grâce auquel, en y logeant un roulement (12), l'arbre de transmission (18), conserve son axe de rotation. La pièce monobloc multifonction, objet de l'invention, peut être réalisée selon une seule technique de fabrication ou en en associant plusieurs d'entre elles : coulage, forgeage, moulage ou usinage, et en utilisant un ou plusieurs composants choisis parmi divers matériaux comme, io par exemple, des métaux, alliages ou divers polymères. Le procédé de montage de l'ensemble multifonction de l'invention comprend : - la fixation de l'élément de support sur le moteur (13) qui consiste à placer les moyens de positionnement (5) sur la face échappement du carter 15 du moteur (13), puis à introduire des moyens de fixation (6) dans les perçages (4) qui traversent le support, pour les enfoncer jusque dans des alésages situés sur la face échappement du carter du moteur (13), - la fixation d'au moins un accessoire (9) sur l'élément de support monobloc qui consiste à positionner un accessoire (9) au niveau de 20 l'interface (7) accessoire du support en enserrant la saillie (7) du support entre les saillies (11) de l'accessoire (9) afin d'aligner leurs alésages (8) respectifs, puis d'y introduire un moyen de fixation (10), - le positionnement d'un roulement (12) dans le palier relais (17) qui consiste à loger le roulement (12) de l'arbre de transmission (18) dans le 25 palier relais (17) formé par le bras de support (3) avant de refermer l'élément de maintien (14) avec un moyen de fixation (16). Une variante de ce procédé de montage permet d'optimiser le temps de montage. Cette variante consiste à réaliser la fixation de l'élément de support sur le carter du moteur (13) après la fixation d'un accessoire (9) sur 30 le support, ou une fois que le positionnement du roulement (12) dans le palier relais (17) intégré au support est réalisé. L'étape de fixation du support sur le carter du moteur (13) consiste alors à positionner comme une seule pièce l'ensemble multifonction, formé par le support avec un ou plusieurs éléments (9 et 12) déjà fixés sur sa structure, sur le carter du moteur (13) puis à introduire des moyens de fixation (6) dans les perçages (4) qui traversent le support, pour les enfoncer jusque dans des alésages situés sur le carter du moteur (13). Les alésages (4) sur l'élément de support sont disposés de façon à toujours demeurer accessibles, même après la fixation d'un ou de plusieurs accessoires (9) sur le support. II doit être évident pour les personnes versées dans l'art que la io présente invention permet des modes de réalisation sous de nombreuses autres formes spécifiques sans l'éloigner du domaine d'application de l'invention comme revendiqué. Par conséquent, les présents modes de réalisation doivent être considérés à titre d'illustration mais peuvent être modifiés dans le domaine défini par la portée des revendications jointes ;The fixing support, which is the subject of the invention, is a multi-function monobloc piece. The support structure has a face (1) preferably substantially planar which may have one or more projections (5) on its opposite side in contact with the motor (13). These projections (5) are suitably oriented to allow positioning on the motor (13) of the multifunction assembly composed of the support, the bearing (12) and the accessory (9). The protrusions (5), placed in the extension of the holes (4) of the support, make it possible to keep the body of the support away from the motor (13). Thus, the fastening means (6), of the rod, stud or wedge type, passes through the support in a bore (4) along an axis perpendicular to the plane of the workpiece, continuing inside a protrusion (5). and is inserted into a tapped bore of the cylinder block of the engine (13) located opposite the fixing point of the support. The placement of these attachment points on the multifunctional part, bores (4) and projections (5), is made such that they are always accessible, even when the accessory (9) is fixed on the support. The fixing support ensures positioning at the periphery of the motor (13) of at least one accessory (9) using one or more fastening means (10). These means may be screws or threaded rods. The flat surface of the support may then have at least one protrusion (7) through which a threaded bore (8) passes. Similar projections (11) on the supported attachment (9) engage the protrusion (7) on the mounting bracket by aligning their respective bores. The threaded fastening means (10) then penetrates the successive threaded bores (8) of the accessory and the support, aligned along an axis parallel to the plane of the fixing support. The placement of these protrusions (7) is made such that the fixing points of the support on the motor housing (13), ie the bores (4), the positioning means (5) and the means fastening (6) remain accessible when the accessory (s) (9) are positioned on the multifunctional part. The mounting bracket positioned on the motor (13) incorporates in its structure a relay bearing (17), as shown in Figures 1 and 2, which is preferably produced according to the model proposed by EP 1 415 847 Al. is a support arm (3) integrated in the mounting bracket, supported, if necessary, by an extension (2) can be inclined or disposed substantially in the same plane as the rest of the part that supports it. This support arm (3) is preferably placed in a plane substantially perpendicular to the plane of its support (2), so that after attachment of the support to the motor housing (13), the axis of rotation of the bearing (12) parallel to that of the crankshaft. This arm (3) surrounds the bearing (12) of the transmission shaft (18) at its upper part and is associated with a holding element (14) which surrounds the transmission shaft at its lower part. . This holding element (14) is openable. It is articulated in a plane perpendicular to the axis of the transmission shaft (18) around a pivot (15) located in the lower third of the diameter of the bearing (12). A second attachment point reversibly secures the holding member (14) at the end of the support arm (3) with a fastening means (16). The support arm (3) and the holding element (14) thus form a relay bearing (17) by which, by housing a bearing (12), the transmission shaft (18) retains its axis of rotation. . The multi-function monobloc piece, which is the subject of the invention, can be made according to a single manufacturing technique or by associating several of them: casting, forging, molding or machining, and by using one or more components chosen from various materials such as for example, metals, alloys or various polymers. The assembly method of the multifunction assembly of the invention comprises: - fixing the support element on the motor (13) which consists of placing the positioning means (5) on the exhaust face of the housing 15 of the engine (13), then to introduce fastening means (6) in the holes (4) which pass through the support, to drive them into bores located on the exhaust face of the engine casing (13), - the attachment of at least one accessory (9) on the one-piece support member which consists in positioning an accessory (9) at the accessory interface (7) of the support by gripping the projection (7) of the support between the projections (11). ) of the accessory (9) to align their respective bores (8), then to introduce a fixing means (10), - the positioning of a bearing (12) in the relay bearing (17) which consists in housing the bearing (12) of the transmission shaft (18) in the relay bearing (17) formed by the support arm (3) before closing the holding member (14) with a fastening means (16). A variant of this mounting method optimizes the mounting time. This variant consists in fixing the support element on the motor casing (13) after attaching an accessory (9) to the support, or once the positioning of the bearing (12) in the bearing relay (17) integrated in the support is realized. The step of fixing the support on the motor housing (13) then consists in positioning as a single piece the multifunction assembly, formed by the support with one or more elements (9 and 12) already fixed on its structure, on the motor casing (13) then to introduce fastening means (6) in the holes (4) which pass through the support, to drive them into bores located on the motor housing (13). The bores (4) on the support member are arranged to always remain accessible, even after attaching one or more accessories (9) to the support. It should be obvious to those skilled in the art that the present invention allows embodiments in many other specific forms without departing from the scope of the invention as claimed. Therefore, the present embodiments should be considered by way of illustration but may be modified in the field defined by the scope of the appended claims;
