Abstract:
1. A drive unit for the coaxial twisting movement of two stabilizer halves of a motor vehicle axle stabilizer, the drive unit comprising: a tubular housing with two housing halves having an interior; a hydraulically movable actuating piston arranged in said interior displaceably in relation to the longitudinal axis of the housing; intercalated cam drive, wherein the displacement in relation to the longitudinal axis is converted by means of said intercalated cam drive into a rotary movement of the housing halves around their common longitudinal axis and wherein the housing halves are fixed with their respective free ends facing away from one another at a stabilizer half each; and a first pretensionable hydraulically actuated releasing piston and a second pretensionable hydraulically actuated releasing piston for making possible the displacing movement of the central actuating piston in the pretensioned positioning and fixing the actuating piston in a middle position in the released position against a spring element, said first actuated releasing piston and said second actuated releasing piston being arranged at the opposite flat sides of the actuating piston.
