Abstract
A connection of the stabilizer parts of a two-part stabilizer to an actuator is usually performed in a positive-locking manner, as a result of which an additional axial securing and hydraulic sealing toward the outside become necessary. To simplify the design and the manufacturing process, it is provided that the teeth between the outer rotary part () and the second stabilizer part () be made clearance-free and welded together by a circumferential weld seam (), wherein the seam area is preheated to a temperature of 350° C. and subsequently cooled to a martensite content of 30% in the microstructure.
