Claim:
A split stabilizer, comprising: a first stabilizer part and a second stabilizer part, the two being connected to one another by an actuator, said actuator comprising an inner rotary part with at least one outwardly directed rotary wing and an outer rotary part with an equal number of inwardly directed rotary wings, said outwardly directed rotary wing and inwardly directed rotary wing forming free spaces between and in cooperation with a coupling sleeve form hydraulic pressure spaces, said inner rotary part being connected with said first stabilizer part, rotating in unison therewith and said outer rotary part being connected with said second stabilizer part, rotating in unison therewith, and a connection for rotation in unison between said outer rotary part and said second stabilizer part is established by teeth between said outer rotary part and said second stabilizer part wherein said teeth between said outer rotary part and said second stabilizer part are clearance-free teeth and said outer rotary part and said second stabilizer part are welded together by a circumferential weld seam with said weld seam closing inner working spaces of said actuator toward the outside in a pressure-sealed manner and axially secures said second stabilizer part in relation to said outer rotary part, said weld seam sealing said teeth.
