1. A device for damping an upper suspension part in at least one spatial direction (X, Y, Z) with respect to a lower suspension part movable relative thereto, comprising:
a spring apparatus which acts along an operating direction between the upper suspension part and the lower suspension part being provided for damping, wherein an actuating element is provided by way of which a force can be introduced into the device bidirectionally along the operating direction of the spring apparatus, the actuating element comprising a drive, a coupling rod coupled to the drive, and at least one spring element on the coupling rod, the actuating element being actuable via a control apparatus,
wherein an operating direction of the coupling rod is perpendicular to the operating direction of the spring apparatus,
wherein the coupling rod is connected to a floating bearing transverse connection,
wherein an angle sensor and an acceleration sensor are provided to detect movements of the upper suspension part with respect to the lower suspension part in the at least one spatial direction and to detect accelerations between the upper suspension part and the lower suspension part, and to send the detected movements and the detected accelerations to the control apparatus, and
wherein the control apparatus controls the actuating element, based on the detected movements and the detected accelerations and via the drive, the coupling rod and the at least one spring element, such that a location of the floating bearing transverse connection within a guide rail is controlled to maintain a desired position of the upper suspension part relative to the lower suspension part.
