Abstract: The invention relates to a stabilizer assembly of a two-track vehicle for stabilizing a rolling movement, the stabilizer assembly being operable on at least two different spring characteristics, comprising a first and a second stabilizer half, each coupled to a wheel of the vehicle, wherein the first and the second stabilizer halves are coupled such that they can rotate relative to each other about their longitudinal axis by means of a spring element, whereby the stabilizer is operable with a first spring characteristic, and wherein the first and the second stabilizer halves can be hydraulically coupled such that they can rotate relative to each other about their longitudinal axis by means of a hydraulic actuator, whereby the stabilizer is operable using at least one second spring characteristic.
