Abstract

Lugs (10) fixed perpendicular to the wall (4) of a vehicle air conditioning casing support a reduction motor (1). Each lug passes through a hole in a foot (5) of the motor from one to the other of the opposite faces (6,7). Each lug has a shoulder (12) opposite the wall and a support for holding each foot by one face (6) against the shoulder. The lug is divided into two branches (15) by a diametral slot (14), beyond the shoulder. Radial projections (16) on each lug which extend beyond the shoulder comprise the support. These are moved elastically to pass through the hole when the motor is installed and finish up opposite the foot second face (7) to hold it in place.

Description

Dispositif pour fixer un motoréducteur sur un boîtier de chauffage de véhicule
L'invention concerne un dispositif pour fixer sur la paroi d'un boîtier un motoréducteur destiné à entraîner un organe mobile disposé à l'intérieur de ce boîtier, notamment pour le réglage d'un flux d'air dans un appareil de chauffage/ventilation ou de climatisation de l'habitacle d'un véhicule, comprenant des chandelles solidaires de ladite paroi et allongées sensiblement perpendiculairement à celle-ci, dont chacune est propre à traverser une ouverture ménagée dans une patte du motoréducteur, de l'une à l'autre de deux faces opposées de celle-ci, et présente un épaulement tourné à l'opposé de la paroi, et des moyens d'appui associés à chaque chandelle pour maintenir ladite patte appliquée par une première desdites faces contre l'épaulement.
Device for fixing a gearmotor to a vehicle heating unit
The invention relates to a device for fixing on the wall of a housing a gearmotor intended to drive a movable member disposed inside this housing, in particular for regulating an air flow in a heating / ventilation device. or air conditioning of the passenger compartment of a vehicle, comprising candles integral with said wall and elongated substantially perpendicular thereto, each of which is capable of passing through an opening formed in a lug of the gearmotor, from one to the other of two opposite faces thereof, and has a shoulder turned away from the wall, and support means associated with each candle to hold said tab applied by a first of said faces against the shoulder.

Dans un tel dispositif, les pattes sont habituellement fixées sur les chandelles par des vis, dont la mise en place et le serrage nécessitent un temps relativement long sur une chaîne de montage. De même, lorsqu'il est nécessaire de démonter le motoréducteur, cette opération est compliquée par la présence des vis.In such a device, the legs are usually fixed to the candles by screws, the establishment and tightening of which require a relatively long time on an assembly line. Similarly, when it is necessary to dismantle the gearmotor, this operation is complicated by the presence of the screws.

Le but de l'invention est de simplifier et de rendre plus rapide l'assemblage du motoréducteur sur le boîtier et son démontage.The object of the invention is to simplify and make faster the assembly of the gear motor on the housing and its disassembly.

L'invention vise notamment un dispositif du genre défini en introduction, et prévoit que les moyens d'appui comprennent des saillies radiales prévues sur la chandelle au-delà de l'épaulement, propres à s'effacer élastiquement pour traverser l'ouverture lors de la mise en place du motoréducteur et à venir ensuite en regard de la seconde face de la patte pour retenir celle-ci. The invention relates in particular to a device of the kind defined in the introduction, and provides that the support means comprise radial projections provided on the candle beyond the shoulder, capable of being elastically erased to pass through the opening during the establishment of the geared motor and then coming next to the second face of the tab to retain it.

Des caractéristiques optionnelles du dispositif selon l'invention, complémentaires ou alternatives, sont énoncées ci-après - La chandelle est divisée en deux branches par une fente diamétrale, au-delà de l'épaulement, les moyens d'appui comprenant deux saillies radiales diamétralement opposées prévues respectivement sur les deux branches.Optional features of the device according to the invention, complementary or alternative, are set out below - The candle is divided into two branches by a diametrical slot, beyond the shoulder, the support means comprising two diametrically radial projections opposite provided respectively on the two branches.

- Il comprend en outre une rondelle souple de rattrapage de jeu entourant chaque chandelle et reposant sur l'épaulement.- It also includes a flexible play take-up washer surrounding each candle and resting on the shoulder.

Les caractéristiques et avantages de l'invention seront exposés plus en détail dans la description ci-après, en se référant aux dessins annexés, sur lesquels: - La figure 1 est une vue de la face d'un motoréducteur destinée à être tournée vers la paroi d'un boîtier d'appareil de chauffage/ventilation ou de climatisation de l'habitacle d'un véhicule, lorsqu'il est fixé sur cette paroi par un dispositif selon l'invention - La figure 2 est une vue du motoréducteur de la figure 1 et d'une chandelle faisant partie du dispositif de fixation, en coupe selon l'axe de la chandelle ; et - La figure 3 est une vue en bout de la chandelle.The characteristics and advantages of the invention will be explained in more detail in the description below, with reference to the accompanying drawings, in which: - Figure 1 is a view of the face of a gearmotor intended to be turned towards the wall of a housing for heating / ventilation or air conditioning of the passenger compartment of a vehicle, when it is fixed to this wall by a device according to the invention - Figure 2 is a view of the gear motor of the Figure 1 and a candle forming part of the fixing device, in section along the axis of the candle; and - Figure 3 is an end view of the candle.

Le motoréducteur 1 illustré aux figures 1 et 2 présente une forme générale parallélépipédique, et comporte un arbre de sortie 2 faisant saillie à partir d'une face 3 destinée à être tournée vers la paroi 4 du boîtier de l'appareil. Deux pattes de fixation sont prévues au voisinage de deux angles opposés de la face 3, chacune d'elle présentant une première face 6 tournée vers la paroi 4 et une seconde face opposée 7, toutes deux parallèles à la face 3. Chaque patte 5 est traversée, de la face 6 à la face 7, par un trou circulaire 8. The gearmotor 1 illustrated in FIGS. 1 and 2 has a generally parallelepiped shape, and comprises an output shaft 2 projecting from a face 3 intended to be turned towards the wall 4 of the housing of the device. Two fixing lugs are provided in the vicinity of two opposite angles of the face 3, each of them having a first face 6 facing the wall 4 and a second opposite face 7, both parallel to the face 3. Each lug 5 is crossing, from face 6 to face 7, by a circular hole 8.

À ces pattes sont associées des chandelles de fixation identiques, dont une seule est illustrée aux figures 2 et 3.These legs are associated with identical fixing jack stands, only one of which is illustrated in FIGS. 2 and 3.

La chandelle 10, moulée d'une seule pièce avec la paroi 4, comprend une région 11 de plus grand diamètre extérieur adjacente à celle-ci et raccordée par un épaulement 12 à une région 13 dont le diamètre extérieur plus petit correspond au diamètre du trou 8. Une fente diamétrale 14 partage la région 13 en deux branches 15 dont chacune présente à son extrémité libre une saillie 16 tournée radialement vers l'extérieur. A l'état assemblé comme montré à la figure 2, la région 13 est engagée dans le trou 8 et les saillies 16 sont situées en regard de la face 7 de la patte, au voisinage immédiat du trou 8, empêchant la patte de s'éloigner de la paroi 4.Une rondelle élastique 17, par exemple en élastomère, entourant la région 13 de la chandelle, est comprimée axialement entre l'épaulement 12 et la face 6 de la patte et applique cette dernière contre les saillies 16 de façon à assurer un positionnement axial stable de la patte. Si la précision de fabrication des pièces est suffisante, la distance entre l'épaulement 12 et les saillies 16 peut être choisie égale à l'épaisseur de la patte, la rondelle 17 étant supprimée.The candle 10, molded in one piece with the wall 4, comprises a region 11 of larger outside diameter adjacent to it and connected by a shoulder 12 to a region 13 whose smaller outside diameter corresponds to the diameter of the hole 8. A diametrical slot 14 divides the region 13 into two branches 15 each of which has at its free end a projection 16 facing radially outwards. In the assembled state as shown in Figure 2, the region 13 is engaged in the hole 8 and the projections 16 are located opposite the face 7 of the tab, in the immediate vicinity of the hole 8, preventing the tab from move away from the wall 4. An elastic washer 17, for example made of elastomer, surrounding the region 13 of the candle, is compressed axially between the shoulder 12 and the face 6 of the tab and applies the latter against the projections 16 so as to ensure stable axial positioning of the tab. If the manufacturing precision of the parts is sufficient, the distance between the shoulder 12 and the projections 16 can be chosen equal to the thickness of the tab, the washer 17 being eliminated.

Lors du montage et du démontage, les branches 15 fléchissent élastiquement l'une vers l'autre pour permettre aux saillies 16 de s'effacer et de passer à travers le trou 8.During assembly and disassembly, the branches 15 flex elastically towards one another to allow the projections 16 to disappear and pass through the hole 8.

Le motoréducteur décrit et représenté ne diffère en rien de ceux qui sont habituellement fixés sur les chandelles par des vis, ce qui permet d'utiliser un même type de motoréducteur pour la fixation selon la technique antérieure et pour la fixation par le dispositif selon l'invention. The gearmotor described and shown does not differ in any way from those which are usually fixed to the candles by screws, which allows the same type of gearmotor to be used for fixing according to the prior art and for fixing by the device according to the invention.
