An upper control arm for a vehicle suspension system having a modulus section of hollow construction for reduced weight. The modulus section of the control arm is of a stamped and welded construction thereby eliminating material weight while reducing the cost of manufacturing. The modulus section has a substantially triangular configuration with a reinforced rim flange along the high compression stress area of the control arm elbow. The reinforced rim flange improves the strength of the control arm without sacrificing the weight reduction provided by the hollow construction.
Cette invention concerne un bras oscillant transversal supérieur de suspension de véhicule comportant des sections résistantes creuses pour alléger la pièce. La section résistante du bras oscillant est réalisée par estampage et soudage, ce qui permet d'alléger la pièce tout en réduisant les coûts de fabrication. La section résistante a un profil essentiellement triangulaire et comporte un rebord de renfort le long de la zone de concentration des contraintes de compression dans la partie coudée du bras. Le rebord de renfort augmente la résistance du bras sans sacrifier l'allégement obtenue par la construction creuse.
