Abstract

The invention relates to a method for tuning the suspension of a motor vehicle. A linear motor (7, LM), in particular a linear electric motor (7, LM), is arranged in the suspension strut of each vibration damper (k₂), in particular controllable vibration damper (k₂), of at least one axle of the two axles of the chassis in a parallel manner relative to said vibration damper (k₂). The linear motor (7, LM) is connected to the sprung mass (m₂) of the motor vehicle on one side of the linear direction of action of the motor and to the unsprung mass (m₁) of the motor vehicle on the other side via the same fixing points as the corresponding vibration damper (k₂). Each linear motor (7, LM) is controlled by means of a controller dependent on measured values which are detected while the vehicle is traveling, and additional forces are added to and/or subtracted from the forces acting on the respective vibration damper (k₂). The invention further relates to a suspension strut (1) for a chassis of a motor vehicle, comprising an upper hinge point (2) for connecting the suspension strut (1) to the sprung mass (m₂) of the motor vehicle, a lower hinge point (3) for connecting the suspension strut (1) to the unsprung mass (m₁) of the motor vehicle, and a pairing of a vibration damper (k₂, 4) and a suspension spring (c₂, 5), said pairing being arranged between the hinge points (2, 3), wherein a linear motor (7, LM) is arranged parallel to said pairing and extends between the same hinge points (2, 3).
