The invention relates to a multi-point guide arm (3, 4) for a chassis of a motor vehicle. The multi-point guide arm (3, 4) has at least one pair of straight profile sections (6) which are spaced apart parallel to one another in the longitudinal extension thereof and which are simultaneously separated from one another between the ends (8) thereof, the profile sections (6) each having an open profile cross-section which is at least substantially C-or U-shaped in cross-section, each end (8) of the profile section (6) is connected to the hollow cylindrical joint receptacle (7) by means of a welded connection (9), and wherein the end (8) of the profile section (6) intersects the cylindrical enclosure-like outer circumferential surface (10) of the hollow cylindrical joint receptacle (7) at least substantially in a T-shape. The invention is characterized in that the welded connections (9) between the profile sections (6) and the hollow cylindrical joint receptacles (7) are each designed as fillet welds (9) having a wedge-shaped weld cross-section, which are implemented exclusively on the outer sides (11) of at least one pair of profile sections (6) facing away from each other, such that the inner sides (19) of the profile sections (6) facing each other are free of welds.

    本发明涉及用于机动车的底盘的多点式导臂(3、4)。多点式导臂(3、4)具有至少一对笔直构造的型材区段(6),该型材区段在其纵向延伸上彼此平行地间隔开并且同时在其端部(8)之间彼此分开,其中,型材区段(6)在横截面中来看相应具有敞开的、至少基本上C形或U形构造的型材横截面,其中,型材区段(6)的每个端部(8)通过焊接连接部(9)与空心柱状的活节容纳部(7)接连,并且其中,型材区段(6)的端部(8)在此与空心柱状的活节容纳部(7)的柱形围罩状的外周面(10)至少基本上T形地相交。本发明的特征在于,在型材区段(6)和空心柱状的活节容纳部(7)之间的焊接连接部(9)相应构造为具有楔形焊缝横截面的角焊缝(9),其仅仅实施在至少一对型材区段(6)的背对彼此的外侧(11)处,从而使得型材区段(6)的面向彼此的内侧(19)无焊缝。
