Switchable stabilizer assembly of a vehicle

A switchable stabilizer assembly of a vehicle, comprising:

• a first stabilizer half and a second stabilizer half, wherein the first stabilizer half and the second stabilizer half are each coupled with a respective wheel of the vehicle;
• and
• a first hydraulic actuator, wherein the first and the second stabilizer halves are coupled rotatably against each other around a respective longitudinal axis by the first hydraulic actuator, wherein the first hydraulic actuator has at least two working chambers filled with a hydraulic medium, wherein the first hydraulic actuator has a first fluid-conducting connection between the at least two working chambers, and wherein a flow cross section of the first fluid-conducting connection is variable by a valve;
• wherein the at least two working chambers of the first hydraulic actuator are not elastically deformable, wherein a first spring element is disposed in the at least two working chambers of the first hydraulic actuator and/or in at least two additional working chambers of the first hydraulic actuator and is supported between a rotor and a stator of the first hydraulic actuator, and wherein the first spring element sets a force-path characteristic curve or a spring rate of the switchable stabilizer assembly with the valve in an open position;
• wherein the flow cross section of the first fluid-conducting connection is variable as a function of a vibration frequency of the switchable stabilizer assembly.
