  • Patent number: 7204494
    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 (4) and the second stabilizer part (2) be made clearance-free and welded together by a circumferential weld seam (18), wherein the seam area is preheated to a temperature of 350° C. and subsequently cooled to a martensite content of 30% in the microstructure.

  • Patent number: 7150458
    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.

  • Publication number: 20030137090
    Abstract: According to prior art, stabilisers are provided with an actuator that is provided with a considerable linear extension which negatively affects the effective springy lengths of the two stabiliser components. Driving comfort is thus decreased. The aim of the invention is to increase the effectively springy lengths of the two stabiliser components. The invention essentially relates to two stabiliser components (1, 1′, 2, 2′) which, together with the respective rotating components (4, 4′, 5, 5′) of the actuator, form one part.
