A connecting arrangement for a stabilizer of a vehicle, with at least one lever that extends transversely to a longitudinal direction. The lever has a bearing eye provided with a non-circular inner circumferential contour. A torsion-bar spring with a rotation axis extends in the longitudinal direction. The torsion-bar spring has an outer circumferential contour, at least at one end, that matches the inner circumferential contour of the bearing eye and which fits into the bearing eye. The wall of the bearing eye is cut through by at least one slit extending in the longitudinal direction, by which two opposite wall sections of the wall are separated from one another. The two wall sections are pressed against the non-circular outer circumferential contour of the torsion-bar spring by at least one releasable clamping element.

Connecting arrangement for a stabilizer of a vehicle

A four-point suspension control arm () is provided for the axle suspension of a rigid axle especially of a utility vehicle. The four-point control arm () has four bearing eyes (), wherein two bearing eyes () can be connected to the rigid axle and two bearing eyes ()are to be connected to the vehicle frame, each in an articulated manner. The four-point control arm () is designed as a one-piece hollow housing (), which can be twisted and is inscribed in the rectangle or trapezoid formed by the bearing eyes. The hollow housing () 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.
