Abstract: A suspension device for a springy suspension of a mass body relative to an understructure, for instance suspension of a driver cabin of a truck relative to a vehicle chassis. The suspension device comprises a spring-/damping configuration, located between the mass body and the understructure, for the damping shock and/or vibration and comprising a Watt linkage configuration with two parallel positioned Watt linkages. A length of at least one of the linkage arms, of the Watt linkage, is adjustable by an actuator. The suspension device is low-maintenance, free of play, and is suitable for determining of the levels of freedom of motion, for instance of a driver cabin, as well as for damping or eliminating unwanted movement of the driver cabin. At the same time, roll motions of the driver cabin, with respect to the understructure or the chassis, can be actively prevented.
