Description

DISPOSITIF DE FIXATION PAR RESSORT DE PRESSION D'UN
RADIATEUR SUR UN ELEMENT DE STRUCTURE.DEVICE FOR FIXING BY PRESSURE SPRING OF A
RADIATOR ON A STRUCTURAL ELEMENT.

L'invention concerne un dispositif de fixation par ressort de pression d'un radiateur de véhicule automobile sur un élément de structure à poutres paral le les qui supportent respectivement le radiateur et le ressort de pression et qui sont situées à deux niveaux différents de ladite structure.The invention relates to a device for fixing a pressure spring of a motor vehicle radiator to a structural element with parallel beams which respectively support the radiator and the pressure spring and which are located at two different levels of said structure. .

On connaît par la publication DE OS 2 634 990 un radiateur qui prend appui sur une poutre inférieure, par l'intermédiaire de pions de centrage et de tampons élastiques et qui est fixé sur une poutre supérieure parallèle décalée longitudinalement par rapport à la poutre inférieure également au moyen de pions de centrage et par ressort de pression qui exerce une force axiale suffisante sur une face du radiateur dans le but d'engager les pions de centrage correspondants dans les tampons élastiques fixés à cette poutre supérieure.We know from the publication DE OS 2 634 990 a radiator which rests on a lower beam, by means of centering pins and elastic buffers and which is fixed on a parallel upper beam offset longitudinally relative to the lower beam also by means of centering pins and by pressure spring which exerts a sufficient axial force on one face of the radiator in order to engage the corresponding centering pins in the elastic buffers fixed to this upper beam.

Mais ce montage est long et malcommode du fait de la nécessité de maintenir le radiateur sous pression pendant la mise en place du ressort. De plus, il est nécessaire de régler une partie des tampons par rapport aux pions de centrage pour rattraper les dispersions des cotes lors de la fabrication du radiateur et du véhicule.However, this assembly is long and inconvenient because of the need to keep the radiator under pressure during the fitting of the spring. In addition, it is necessary to adjust a part of the buffers relative to the centering pins to make up for the dispersion of the dimensions during the manufacture of the radiator and of the vehicle.

Le but de l'invention est de pallier l'inconvénient précédent en proposant de façon plus générale un dispositif de fixation rapide d'une pièce par rapport à une structure. The object of the invention is to overcome the above drawback by proposing, more generally, a device for quickly fixing a part with respect to a structure.

Un autre but de l'invention est un dispositif de fixation utilisant un fil de torsion dont la configuration permet la manoeuvre dudit dispositif.Another object of the invention is a fixing device using a twist wire whose configuration allows the operation of said device.

Conformément à l'invention, le ressort de pression est constitué par un fil de torsion dont les extrémités sont ancrées sur la poutre supérieure et qui s'étend le long de cette poutre jusqu'à une zone de compression transversalement décalée par rapport à la poutre en direction du sommet du radiateur, qui est formée par une boucle élastique ouverte dudit fil dont les bouts sont raccordés aux extrémités du fil ancrées sur la poutre.According to the invention, the pressure spring consists of a torsion wire, the ends of which are anchored on the upper beam and which extends along this beam to a compression zone transversely offset with respect to the beam towards the top of the radiator, which is formed by an open elastic loop of said wire, the ends of which are connected to the ends of the wire anchored on the beam.

Dans le dispositif réalisé, il est particulièrement aisé de dissimuler l'ensemble du ressort dans la poutre et de prévoir un passage de la branche de manoeuvre et-de la boucle élastique correspondante à la zone de compression du sommet du radiateur.In the device produced, it is particularly easy to conceal the entire spring in the beam and to provide a passage for the operating branch and the corresponding elastic loop to the compression zone of the top of the radiator.

Il y a également lieu de noter que l'effort de compression sur le radiateur est réparti uniformément le long du fil de torsion jusqu'à ses extrémités ancrées sans affecter la rigidité de la poutre dont les fixations à la structure du véhicule sont voisines desdites extrémités ancrées.It should also be noted that the compressive force on the radiator is distributed uniformly along the torsion wire to its anchored ends without affecting the rigidity of the beam whose fastenings to the vehicle structure are close to said ends anchored.

La description qui suit d'un mode de réalisation de l'invention fait référence au dessin annexé sur lequel - la figure 1 est une vue en perspective du dispositif
avec arrachement partiel de la poutre supérieure - la figure 2 est une vue en coupe du dispositif dans
le plan 2-2 de la figure 1. The following description of an embodiment of the invention refers to the attached drawing in which - Figure 1 is a perspective view of the device
with partial cutaway of the upper beam - Figure 2 is a sectional view of the device in
plan 2-2 of figure 1.

On reconnait sur la figure 2 un radiateur 1 de refroidissement moteur de véhicule automobile devant être monté à l'intérieur du compartiment moteur et entouré de traverses ou de poutres métalliques environnantes telles qu'une poutre inférieure 2, une poutre supérieure 3 décalée transversalement et longitudinalement de la première.We recognize in Figure 2 a motor vehicle engine cooling radiator 1 to be mounted inside the engine compartment and surrounded by crosspieces or surrounding metal beams such as a lower beam 2, an upper beam 3 offset transversely and longitudinally of the first.

Le radiateur 1 repose de façon connue sur la poutre inférieure 2 par l'intermédiaire de pions de centrage 5 clipsés dans ladite poutre avec interposition de tampons élastiques 6 en caoutchouc formant butée, de manière à laisser un jeu 7 entre la base 8 du radiateur et la poutre. Ce système permet de positionner et de fixer rapidement le radiateur sur la poutre inférieure 2 la moins accessible au montage.The radiator 1 rests in a known manner on the lower beam 2 by means of centering pins 5 clipped into said beam with the interposition of elastic buffers 6 made of rubber forming a stop, so as to leave a clearance 7 between the base 8 of the radiator and beam. This system makes it possible to quickly position and fix the radiator on the lower beam 2 which is the least accessible for mounting.

Conformément à l'invention, le sommet 9 du radiateur 1 est maintenu verticalement sous pression au moyen d'un ressort 10 constitué par un fil de torsion dont les extrémités recourbées ll sont ancrées sur la poutre supérieure 3.According to the invention, the top 9 of the radiator 1 is held vertically under pressure by means of a spring 10 constituted by a twist wire whose curved ends ll are anchored on the upper beam 3.

La poutre 3 est constituée par un profil métallique à section ouverte qui possède deux flancs opposés 12, 13 orientés vers le radiateur 1 entre lesquels s'étendent les extrémités ll du ressort. Le ressort 10 s'étend le long et sous le flanc longitudinal supérieur 12 et ses extrémités recourbées ll sont ancrées dans le flanc longitudinal opposé 13.The beam 3 is constituted by a metallic profile with an open section which has two opposite sides 12, 13 oriented towards the radiator 1 between which the ends ll of the spring extend. The spring 10 extends along and under the upper longitudinal flank 12 and its curved ends 11 are anchored in the opposite longitudinal flank 13.

Le flanc supérieur 12 porte deux paliers d'articulation 14 maintenus au moyen d'un rivet expansible 15 emboîté dans ledit flanc. The upper side 12 carries two articulation bearings 14 held by means of an expandable rivet 15 fitted into said side.

Entre les paliers d'articulation 14 s'étend une boucle élastique ouverte 16 dont deux branches parallèles 16a, 16b s'étendent vers la zone de compression 17 du sommet du radiateur 1 transversalement décalée par rapport à la poutre 3. La zone de compression 17 du radiateur 1 porte un tampon élastique 18 calé entre les ailes verticales du profilé 19 situé au-sommet du radiateur et sur lequel s'exerce l'effort de pression exercé par les branches 16a, 16b de la boucle 16 formée dans la partie médiane du fil de torsion.Between the articulation bearings 14 extends an open elastic loop 16 of which two parallel branches 16a, 16b extend towards the compression zone 17 of the top of the radiator 1 transversely offset with respect to the beam 3. The compression zone 17 of the radiator 1 carries an elastic pad 18 wedged between the vertical wings of the profile 19 located at the top of the radiator and on which the pressure force exerted by the branches 16a, 16b of the loop 16 formed in the middle part of the twist wire.

Dans le dispositif ainsi réalisé, le ressort 10 peut être prémonté sur la poutre 3 tandis que la boucle 16 présente une branche de manoeuvre 20 qui permet la préhension de la boucle 16 dans le but d'exercer un couple de torsion dans le ressort 10 en y laissant subsister un écartement suffisant entre le radiateur 1 et la boucle pour autoriser un basculement du radiateur 1 autour de la poutre inférieure 2 dans le but d'assurer sa mise en place ou son retrait.  In the device thus produced, the spring 10 can be pre-assembled on the beam 3 while the loop 16 has an operating branch 20 which allows the gripping of the loop 16 in order to exert a torque in the spring 10 in leaving sufficient space between the radiator 1 and the loop to allow the radiator 1 to tilt around the lower beam 2 in order to ensure its installation or removal.
