Abstract

L’invention concerne un bras inférieur de suspension comprenant une pièce métallique plate emboutie (20) comportant d’une part deux branches (22, 24) inclinées en définissant un extrados (26), et une branche intermédiaire (54) s’étendant en saillie dudit extrados à l’opposé de l’une (22) desdites deux branches, et comportant d’autre part deux rebords d’extrados (60, 62) s’étendant dans ledit extrados (26) en convergeant l’un vers l’autre en formant une extrémité libre en U (64), ladite extrémité libre en U présentant deux bords échancrés parallèles (66, 68) réunis par un bord de fond en saillie (70). Le bras comprend en outre une autre pièce métallique plate (76) reliée à ladite pièce métallique plate emboutie (20). Et ladite autre pièce métallique (76) plate comprend une languette (114) s’étendant dans ladite branche intermédiaire (54) entre lesdits deux rebords (60, 62) convergents pour venir en appui contre ladite douille (122) à l’opposé dudit bord de fond en saillie (70). Figure à publier avec l’abrégé : Fig. 6The invention relates to a lower suspension arm comprising a flat, stamped metal part (20) having, on the one hand, two inclined arms (22, 24) defining an extrados (26), and an intermediate arm (54) projecting from said extrados opposite one (22) of said two arms, and having, on the other hand, two extrados edges (60, 62) extending into said extrados (26) converging towards each other to form a free U-shaped end (64), said free U-shaped end having two parallel notched edges (66, 68) joined by a projecting bottom edge (70). The arm further comprises another flat metal part (76) connected to said flat, stamped metal part (20). And said other flat metal piece (76) includes a tab (114) extending in said intermediate arm (54) between said two converging edges (60, 62) to bear against said socket (122) opposite said projecting bottom edge (70). Figure to be published with the abbreviation: Fig. 6
