Abstract:
A four-point suspension control arm (1) is provided for the axle suspension of a rigid axle especially of a utility vehicle. The four-point control arm (1) has four bearing eyes (7, 8, 9, 10), wherein two bearing eyes (9, 10) can be connected to the rigid axle and two bearing eyes (7, 8)are to be connected to the vehicle frame, each in an articulated manner. The four-point control arm (1) is designed as a one-piece hollow housing (2, 3, 4, 5, 6), which can be twisted and is inscribed in the rectangle or trapezoid formed by the bearing eyes. The hollow housing (2, 3, 4, 5, 6) is formed essentially by a tube, which is arranged horizontally in respect to the vehicle and is open on both sides, with a cross section ranging from an essentially rounded rectangular to O-shaped.
