Abstract:
1. Stabilizer device for an axle of a motor vehicle, the stabilizer device comprising a roll stabilizer and an actuatorically switchable coupling device wherein the roll stabilizer is formed divided into a left stabilizer half and into a right stabilizer half and the stabilizer halves are positively connectable with each other by means of the coupling device, the coupling device comprising two axially as well as radially overlapping clutch devices, which create at least a tangential gap and are connected each with one stabilizer half respectively, and a locking sleeve axially shiftable back and forth between a locking position and unlocking position wherein the locking sleeve has at least one locking finger, which can be accommodated in the tangential gap between the clutch devices in the locking position, further comprising: a shifting device for shifting the locking sleeve by means of mechanical power transmission wherein the shifting device comprises a servo-electric transmission drive element, wherein one or more of the clutch devices and the locking fingers comprise active surfaces, each of which are formed in a wedge shape with steps such that a first step of the active surfaces has a self-blocking wedge angle, whereas a second step of the active surfaces does not have a self-blocking wedge-angle.
