Abstract: A drive unit is provided for the coaxial twisting movement of two stabilizer halves of a motor vehicle axle stabilizer with a tubular housing. Two housing halves are provided having an interior of which a hydraulically movable actuating piston is arranged displaceably in relation to the longitudinal axis of the housing. The longitudinal displacement of the piston is converted by an intercalated cam drive into a rotary movement of the housing halves around their common longitudinal axis. The housing halves are fixed with their respective free ends facing away from one another at a stabilizer halve. A hydraulically actuated releasing piston is pretensioned against a spring element and arranged at each opposite flat sides of the actuating piston, wherein the releasing pistons make possible the displacing movement of the central actuating piston in the pretensioned position and fix the actuating piston in its middle position in the released position.
