<p>The invention relates to a four-point suspension arm (1) for the suspension of a rigid axle, in particular of a utility vehicle. Said suspension arm (1) comprises four bearing lugs (7, 8, 9, 10), two bearing lugs (9, 10) being respectively connected in an articulated manner to the rigid axle and two bearing lugs (7, 8) being connected to the vehicle frame. The four-point suspension arm (1) is configured as a one-piece, flexible hollow housing (2, 3, 4, 5, 6) lying within the quadrilateral or trapezium that is formed by the bearing lugs. The inventive four-point suspension arm (1) is characterised in that the hollow housing (2, 3, 4, 5, 6) is configured essentially from a tube that is open on both sides facing towards the vehicle with a substantially rounded rectangular cross-section or O-shaped cross-section.</p> |
