Description

AGENCEMENT D UN TRAIN DE ROUE DE VEHICULE ARRANGEMENT OF A VEHICLE WHEEL TRAIN
AUTOMOBILEAUTOMOBILE
La présente invention concerne un agencement de train de roue d'un véhicule automobile, dans lequel une fusée porte un moyeu de roue, cette fusée étant solidaire d'un porte fusée, et dans lequel un élément de suspension est rapporté soudé sur le porte fusée, cet élément de suspension étant formé d'un tube amortisseur soudé au porte fusée et d'un ressort disposé autour du tube amortisseur.The present invention relates to a wheel axle arrangement of a motor vehicle, in which a rocket carries a wheel hub, the rocket being secured to a rocket door, and wherein a suspension element is attached welded to the rocket door. , this suspension element being formed of a damping tube welded to the rocket door and a spring disposed around the damping tube.
A titre d'exemple, un tel agencement est divulgué dans le document EP 0 127 869, dans lequel un ensemble support est composé de différents éléments formant un porte fusée, qui vient se solidariser sur le tube amortisseur.By way of example, such an arrangement is disclosed in EP 0 127 869, in which a support assembly is composed of different elements forming a rocket door, which is secured to the damping tube.
La présente invention vise à proposer une alternative à l'agencement tel qu'évoqué ci dessus, caractérisé en ce que le porte fusée est formé par un unique composant sensiblement en forme d'arc, dont une première extrémité supérieure est solidarisée au tube amortisseur à une première hauteur, et dont une deuxième extrémité inférieure est solidarisée au tube amortisseur à une deuxième hauteur inférieure à la première, et en ce que l'extrémité inférieure du ressort de suspension prend appui directement sur la partie supérieure de la première extrémité supérieure du porte fusée.The present invention aims to propose an alternative to the arrangement as evoked above, characterized in that the rocket door is formed by a single substantially arc-shaped component, a first upper end is secured to the damper tube to a first height, and a second lower end is secured to the damper tube at a second height lower than the first, and in that the lower end of the suspension spring bears directly on the upper part of the first upper end of the door rocket.
Selon une caractéristique de l'invention, la première extrémité supérieure du porte fusée peut présenter un profil apte à faire le tour du tube amortisseur, le porte fusée étant soudée sur toute la périphérie du tube amortisseur.According to a feature of the invention, the first upper end of the rocket door may have a profile adapted to go around the damper tube, the rocket door being welded over the entire periphery of the damper tube.
D'autres avantages et caractéristiques de l'invention apparaîtront à la lecture de la description qui va suivre, pour la compréhension de laquelle on se reportera aux figures annexées, parmi lesquelles : la figure 1 est une vue en coupe d'un agencement d'un train de roue selon l'invention, la figure 2 est une représentation schématique d'un agencement d'un train de roue, le porte fusée étant réalisé selon un premier mode de réalisation, la figure 3 est une vue en coupe du porte fusée et du tube amortisseur, selon le mode de réalisation représenté à la figure 2, et avec une variante de conception du porte fusée, la figure 4 est une représentation schématique d'un agencement d'un train de roue, le porte fusée étant réalisé selon un deuxième mode de réalisation.Other advantages and characteristics of the invention will appear on reading the description which follows, for the understanding of which reference will be made to the appended figures, among which: FIG. 1 is a sectional view of an arrangement of a wheel train according to the invention, FIG. 2 is a schematic representation of an arrangement of a wheel train, the rocket door being made according to a first embodiment, FIG. 3 is a sectional view of the rocket door and the damping tube, according to the method of FIG. embodiment shown in Figure 2, and with a design variant of the rocket door, Figure 4 is a schematic representation of an arrangement of a wheel train, the rocket door being made according to a second embodiment.
Tel que représenté, une fusée 2 de roue est disposée relativement à un porte fusée 4, de sorte que cette fusée 2 est solidaire du porte fusée 4, et que la roue est montée à rotation autour d'un axe transversal formé par la fusée 2. Selon l'invention, le porte fusée 4 est formé par un unique composant sensiblement en forme d'arc, qui présente une première extrémité 41 supérieure et une deuxième extrémité 42 inférieure.As shown, a rocket 2 wheel is disposed relative to a rocket door 4, so that the rocket 2 is integral with the rocket door 4, and that the wheel is rotatably mounted about a transverse axis formed by the rocket 2 According to the invention, the rocket door 4 is formed by a single substantially arcuate component, which has a first upper end 41 and a second lower end 42.
L'agencement de train de roue comporte un élément de suspension, formé d'un tube amortisseur 62 sur le pourtour duquel est monté un ressort de suspension 64. L'élément de suspension est rendu solidaire du porte fusée 4 par soudage du tube amortisseur 62 sur le porte fusée 4.The wheel train arrangement comprises a suspension element, formed of a damping tube 62 on the periphery of which is mounted a suspension spring 64. The suspension element is secured to the rocket door 4 by welding the damping tube 62 on the rocket door 4.
Selon l'invention, le porte fusée 4 est formé par un unique composant sensiblement en forme d'arc, comprenant une face plane 43 sur laquelle est solidarisée la fusée 2, une première extrémité 41 supérieure solidarisée au tube amortisseur 62 à une première hauteur, et une deuxième extrémité 42 inférieure solidarisée à une deuxième hauteur du tube amortisseur 62. La forme en arc du porte fusée 4 et la double soudure de ce porte fusée 4 sur le tube d'amortisseur permet un bon encastrement du tube d'amortisseur dans le porte fusée 4, et un rattrapage des jeux optimisé.According to the invention, the rocket door 4 is formed by a single substantially arc-shaped component, comprising a flat face 43 on which is fixed the rocket 2, a first upper end 41 secured to the damping tube 62 at a first height, and a second lower end 42 secured to a second height of the damping tube 62. The arcuate shape of the rocket door 4 and the double weld of the rocket door 4 on the damper tube allows a good fit of the damper tube in the rocket door 4, and an optimized catch-up games.
Selon un premier mode de réalisation, représenté notamment aux figures 1 à 3, la première extrémité 41 supérieure du porte fusée 4 présente un profil apte à faire le tour du tube amortisseur 62. Ce profil, embouti, est obtenu dans la même tôle que le reste du porte fusée 4, et permet la fixation autour du tube amortisseur 62 sans ajouter de pièces supplémentaires.According to a first embodiment, shown in particular in Figures 1 to 3, the first end 41 of the rocket door 4 has a profile adapted to go around the damper tube 62. This profile, stamped, is obtained in the same sheet as the rest of the rocket door 4, and allows the fixing around the damper tube 62 without adding additional parts.
Un tel agencement peut permettre de lier l'extrémité inférieure du ressort au porte fusée 4, sans ajout d'une coupelle de suspension, par une opération d'emboutissage particulière sur le profil de l'extrémité supérieure du porte fusée 4. Un outil permet alors de réaliser une préforme d'accueil 65 du ressort de suspension 64. Dans ce cas, l'extrémité inférieure du ressort de suspension 64 prend appui directement sur la partie supérieure de la première extrémité 41 supérieure, qui s'étend tout autour du tube amortisseur 62 et qui présente une largeur radiale apte à recevoir la spire d'extrémité du ressort de suspension 64.Such an arrangement can make it possible to link the lower end of the spring to the rocket door 4, without adding a suspension cup, by a particular stamping operation on the profile of the upper end of the rocket door 4. A tool allows then to realize a host preform 65 of the suspension spring 64. In this case, the lower end of the suspension spring 64 bears directly on the upper part of the first end 41, which extends all around the tube damper 62 and which has a radial width adapted to receive the end turn of the suspension spring 64.
Une variante de conception est représenté à la figure 3, dans laquelle les orifices permettant le passage du tube amortisseur 62 dans la deuxième extrémité inférieure 42 et dans la première extrémité supérieure 41 du porte fusée présentent des bords tombés de sorte que les bords tombés réalisés dans la deuxième extrémité inférieure 42 sont dirigés vers le haut, et donc en regard des bords tombés réalisés dans la première extrémité supérieure 41 qui eux sont dirigés vers le bas.A variant of the design is shown in FIG. 3, in which the orifices permitting the passage of the damping tube 62 into the second lower end 42 and into the first upper end 41 of the rocket door have fallen edges so that the fallen edges made in the second lower end 42 are directed upwards, and therefore opposite the fallen edges made in the first upper end 41 which are directed downwards.
Dans les deux cas présentés, le premier mode de réalisation du porte fusée permet d'envisager la solidarisation du tube amortisseur avec le porte fusée par deux opérations différentes. Le porte fusée 4 peut être soudé sur toute la périphérie du tube amortisseur 62, au niveau de chaque orifice de passage du tube, ou bien ce tube amortisseur 62 peut être monté à force par emmanchement dans les orifices des extrémités supérieure et inférieure du porte fusée. Un tel emmanchement permettrait de ne pas avoir d'opérations de soudure à proximité du tube amortisseur.In both cases presented, the first embodiment of the rocket door makes it possible to consider the joining of the damper tube with the rocket door by two different operations. The rocket door 4 may be welded over the entire periphery of the damping tube 62, at each passage opening of the tube, or this damping tube 62 may be force-fitted by fitting into the orifices of the upper and lower ends of the rocket door . Such a fitting would not have welding operations near the damper tube.
Selon un deuxième mode de réalisation, représenté à la figure 4, le porte fusée 4 présente des extrémités inférieure et supérieure ouvertes en demi cercle, et la fixation du porte fusée sur le tube amortisseur se fait par soudage des extrémités sur le tube. Cette conception du porte fusée permet une fabrication simplifiée, un coût moindre et un temps de montage plus rapide. Elle nécessite la présence d'une coupelle d'amortisseur non représenté pour que le ressort de suspension puisse venir prendre appui. II convient de noter que les deux modes de réalisation représentés ci-dessus pourraient être mixés, pour obtenir ainsi un porte fusée en forme d'arc dont l'extrémité supérieure présente un profil apte à entourer le tube amortisseur, et dont l'extrémité inférieure est ouverte en demi cercle.According to a second embodiment, shown in Figure 4, the rocket door 4 has lower and upper ends open in a semi-circle, and the fixing of the rocket door on the damping tube is done by welding the ends on the tube. This rocket door design allows for simplified manufacturing, lower cost and faster assembly time. It requires the presence of a damper cup not shown so that the suspension spring can come to bear. It should be noted that the two embodiments shown above could be mixed, to thereby obtain a bow-shaped rocket door whose upper end has a profile adapted to surround the damping tube, and whose lower end is open in a half circle.
Un bras de suspension 8 est articulé au porte fusée 4 par des moyens formant rotule 10. Telle que représentée, cette articulation sur le porte fusée 4 est réalisée entre la face plane sur laquelle est solidarisée la fusée et la zone de soudure au tube amortisseur 62. Dans un contexte de véhicule à bas coût, le porte fusée 4 est composé d'une unique pièce en tôle et emboutie. A suspension arm 8 is articulated to the rocket door 4 by means forming a ball 10. As shown, this articulation on the rocket door 4 is formed between the flat face on which is fixed the rocket and the welding zone to the damping tube 62 In a context of a low-cost vehicle, the rocket door 4 is composed of a single sheet metal part and stamped.
