Suspension system with an adjustable spring

The wheel suspension includes a vehicle structure (12) from which a wheel (11) is attached by connecting rods. It has a wheel carrier (15) and at least one coil compression spring (18) supported by the vehicle structure on one side and the wheel carrier on the other. The spring rigidity is adjustable. The coil spring is arranged so that its force direction line (W) deviates from the geometrical center line (L) of the spring. The turning mechanism is provided to enable the deviation to be adjusted. The spring seat (19) is motor-driven.
