Abstract

It is a purpose in a divided stabilizer to increase the springy lengths of the two stabilizer components. The stabilizer components (1, 1′, 2, 2′) have respective rotary parts (4, 4′, 5, 5′) attached and the rotary parts in turn have respective rotary wings (14, 16) attached. A cover flange (8′) is formed at the outer rotary part (4′). An outer rotary wing (14) is radially inwardly directed and attached to the outer rotary part (4′). An inner rotary wing (16) is radially outwardly directed and is attached to the inner rotary part (5′). A second stabilizer part (2, 2′) is attached to the inner rotary part (5′), wherein the outer rotary part (4′) with the outer rotary wing (14) moves relative to the liner rotary part (5′) with the inner rotary wing (16) up to the point where the outer rotary wing (14) contacts the inner rotary wing (16). The rotary wings (14, 16) are rotatable relative to each other up to a predetermined angle. The stabilizer is coordinated in parallel to an axle of a vehicle.
