Abstract

Suspension arm for a motor vehicle, pivoting about a shaft 2 integral with the structure of the vehicle connecting a wheel to a torsion bar 3 that is generally parallel with this shaft 2 and comprising a body 4 of pressed sheet metal and a tubular hub 5 surrounding the pivot shaft 2, in addition to a rigid piece 9 to which the torsion bar 3 is anchored, the arm being characterised in that the rigid piece 9 is integral with the tubular hub 5 of the arm and is supported, above this hub 5, by the edge 10 of a stiffening rib 11 running along the body 4 approximately perpendicularly to the hub 5.

Description

L'invention est relative aux bras de suspension, pour véhicules automobiles, qui pivotent autour d'un axe solidaire de la structure du véhicule et qui relient une roue à une barre de torsion sensiblement parallèle à cet axe. The invention relates to suspension arms, for motor vehicles, which pivot about an axis integral with the structure of the vehicle and which connect a wheel to a torsion bar substantially parallel to this axis.

L'invention concerne plus particulièrement ceux de ces bras qui comportent un corps principal en tôle emboutie et un moyeu tubulaire entourant 1 axe de pivotement. L'ancrage d'une extrémité de la barre de torsion s effectue alors généralement par 1' intermé- diaire d'une pièce rigide fixée par vissage ou par soudage au corps en tôle ou au moyeu tubulaire. Mais lorsque le bras est réalisé en tôle relativement mince pour être léger, il risque de se produire à l'usage, au droit de la fixation de ladite pièce rigide. des déformations ou même des arrachements du bras consécutivement aux importants efforts transmis par la barre de torsion. The invention relates more particularly to those of these arms which comprise a main body of pressed sheet metal and a tubular hub surrounding 1 pivot axis. The anchoring of one end of the torsion bar is then generally carried out by means of a rigid part fixed by screwing or by welding to the sheet metal body or to the tubular hub. But when the arm is made of relatively thin sheet metal to be light, it may occur during use, in line with the fixing of said rigid part. deformations or even tearing of the arm following the significant forces transmitted by the torsion bar.

L'invention a pour but de réaliser un bras de suspension, particulièrement simple et léger, présentant une fiabilité satisfaisante au voisinage de l'ancrage d'une barre de torsion. The object of the invention is to produce a suspension arm, which is particularly simple and light, having satisfactory reliability in the vicinity of the anchoring of a torsion bar.

Selon l'invention, la piece rigide d'ancrage de la barre de torsion est solidaire du moyeu tubulaire du bras et prend appui, au-dessus de ce moyeu. According to the invention, the rigid anchoring part of the torsion bar is integral with the tubular hub of the arm and bears, above this hub.

sur le bord d'une nervure de raidissement s'détendant sur le corps sensiblement perpendiculairement au moyeu.on the edge of a stiffening rib extending over the body substantially perpendicular to the hub.

Suivant deux modes de réalisation de l'in- vention
- la nervure est formée directement par emboutissage- dans une demi-coquille supérieure constitutive du corps en tôle;
- ou bien la nervure est rapportée par soudage sur la face supérieure du corps,
Deux exemples de réalisation d'un bras de suspension selon l'invention sont décrits ci-après, avec référence aux dessins parmi lesquels
- la Figure 1 est une vue en perspective d'un premier mode de realisation du bras associé à un axe de pivotement et à une barre de torsion;
- la Figure 2 est une vue en élévation du bras, de la Figure 1, nu;
- la Figure 3 est une vue de dessus du bras des Figures 1 et 2;
- les Figures 4 à 6 sont des vues en coupe suivant les lignes IV-IV de la Figure 3, V-V et VI-VI de la Figure 2; et,
- la Figure 7 est une vue analogue à celle de la Figure 6, d'un bras suivant une variante de réalisation.According to two embodiments of the invention
- The rib is formed directly by stamping - in an upper half-shell constituting the sheet metal body;
- or else the rib is attached by welding to the upper face of the body,
Two embodiments of a suspension arm according to the invention are described below, with reference to the drawings among which
- Figure 1 is a perspective view of a first embodiment of the arm associated with a pivot axis and a torsion bar;
- Figure 2 is an elevational view of the arm, of Figure 1, naked;
- Figure 3 is a top view of the arm of Figures 1 and 2;
- Figures 4 to 6 are sectional views along lines IV-IV of Figure 3, VV and VI-VI of Figure 2; and,
- Figure 7 is a view similar to that of Figure 6, of an arm according to an alternative embodiment.

On voit sur la Figure 1 un bras de suspension 1 associé à un axe de pivotement 2 et à une barre de torsion 3 sensiblement parallèle à l'axe 2. Le bras 1 comporte un corps principal 4 en tôle emboutie, aux deux extrémités duquel sont respectivement soudés un moyeu tubulaire 5 entourant l'axe 2 et un embout cylindrique 6 propre à recevoir l'arbre d'une roue (non représenté). We see in Figure 1 a suspension arm 1 associated with a pivot axis 2 and a torsion bar 3 substantially parallel to the axis 2. The arm 1 comprises a main body 4 of pressed sheet metal, at the two ends of which are respectively welded a tubular hub 5 surrounding the axis 2 and a cylindrical end piece 6 suitable for receiving the shaft of a wheel (not shown).

Le bras 1, sensiblement horizontal, ainsi que l'axe 2 et la barre 3, est destiné à relier cette roue à la structure d'un véhicule, structure à laquelle sont fixés, de manière classique non représentée, l'axe 2 et l'une des extrémités de la barre 3. The arm 1, substantially horizontal, as well as the axis 2 and the bar 3, is intended to connect this wheel to the structure of a vehicle, structure to which are fixed, in a conventional manner not shown, the axis 2 and the 'one end of the bar 3.

L'autre extrémité 7 de cette barre 3 est ancrée. par l'intermédiaire d'une douille dentelée 8, sur une pièce rigide métallique 9 traversée par le moyeu 5 et en appui, au-dessus de ce dernier, sur le bord 10 d'une nervure de raidissement 11 qui s'étend sur le corps 4 perpendiculairement au moyeu 5, la section de la nervure 11 s'amenuisant en s'approchant de 1 embout cylindrique 6. The other end 7 of this bar 3 is anchored. by means of a serrated sleeve 8, on a rigid metallic piece 9 traversed by the hub 5 and resting, above the latter, on the edge 10 of a stiffening rib 11 which extends over the body 4 perpendicular to the hub 5, the section of the rib 11 decreasing as it approaches 1 cylindrical end piece 6.

La pièce 9 est rendue solidaire du moyeu 5 par emmanchement serré et/ou par soudage; en variante, la solidarisation de la pièce d'ancrage et du moyeu est obtenue en les réalisant monopiéce. par exemple par moulage ou par forgeage. The part 9 is made integral with the hub 5 by tight fitting and / or by welding; alternatively, the attachment of the anchoring part and the hub is obtained by making them one piece. for example by molding or forging.

Le corps principal 4 est constitué de deux demi-coquilles 12. 13 soudées entre elles suivant un plan de jonction situé au niveau des axes géométriques du moyeu 5 et de l'embout 6, et une soudure 15 maintient la partie supérieure de la pièce 9 en appui sur le bord 10,
La nervure 11 est formée directement par emboutissage dans la demi-coquille supérieure 12. En variante, comme visible à la Figure 7, la nervure lia peut être rapportée par soudage sur la demi-coquille supérieure 12a du corps 4a.The main body 4 consists of two half-shells 12. 13 welded together according to a junction plane located at the geometrical axes of the hub 5 and of the end piece 6, and a weld 15 holds the upper part of the part 9 resting on edge 10,
The rib 11 is formed directly by stamping in the upper half-shell 12. As a variant, as visible in FIG. 7, the rib 11a can be attached by welding to the upper half-shell 12a of the body 4a.

A la Figure 5, sont représentes, à l'inte- rieur du moyeu tubulaire 5 et emmanchés respectivement à ses deux extrémités, deux paliers 16 légèrement souples munis chacun d'une douille interne 17 propre à recevoir l'axe de pivotement 2. In FIG. 5 are shown, inside the tubular hub 5 and fitted respectively at its two ends, two slightly flexible bearings 16 each provided with an internal bushing 17 suitable for receiving the pivot axis 2.

Le bras proposé selon l'invention s'avère particulièrement résistant, même si la tôle utilisée est relativement mince. car les efforts généralement importants transmis au bras par la barre de torsion 3, et orientés dans le sens indiqué par la flèche F à la
Figure 2, tendent à maintenir la partie superieure de la pièce d'ancrage 9 en appui sur le bord 10 de la nervure. La- force de cet appui étant dirigée vers l'embout cylindrique 6, perpendiculairement à l'axe de pivotement 2, la soudure 15 n'est soumise qu'à de faibles contraintes et la nervure 11, à peu prés alignée avec ladite force d'appui, travaille essentiellement en compression et procure un renforcement maximal du bras. The arm proposed according to the invention proves to be particularly resistant, even if the sheet used is relatively thin. because the generally large forces transmitted to the arm by the torsion bar 3, and oriented in the direction indicated by the arrow F at the
Figure 2, tend to keep the upper part of the anchor piece 9 in abutment on the edge 10 of the rib. The force of this support being directed towards the cylindrical end piece 6, perpendicular to the pivot axis 2, the weld 15 is only subjected to low stresses and the rib 11, roughly aligned with said force d 'support, works mainly in compression and provides maximum reinforcement of the arm.
