Switchable stabilizer arrangement of a vehicle

The invention relates to a switchable stabilizer arrangement of a vehicle, in particular for roll stabilization. Comprising a first and a second respectively coupled to a wheel of the vehicle stabilizer half, wherein the first and the second stabilizer half are rotatable relative to each coupled to their longitudinal axis by means of a hydraulic semi-active actuator. The actuator in this case has at least two filled working chambers with a hydraulic medium and comprising at least one fluid-conducting connection between the at least two working chambers whose passage cross section is variable. The working chambers of the actuator are in turn not elastically deformable. Instead of the actuator and / or a spring element is arranged in at least two working chambers of the actuator in the at least two working chambers, which is supported between a rotor and a stator of the actuator.
