Abstract: An improve spring rate of a stabilizer is provided with an extended spring length. An inner rotary part (4) of an oscillating motor (2) and a second stabilizer part (1) are connected to one another with a non-positive connection (force transmitting friction connection) designed such that the axial center of the force-transmitting length of the second stabilizer part (1) and the axial center of the force-transmitting length of the inner rotary part (4) are located on a common radial plane. The non-positive connection between the inner rotary part (4) and a fitting cylinder (14) of the second stabilizer part (1) is formed either from a shrunk-on fit or a toothed part (21) and a fitting part (22), wherein the toothed part (21) and the fitting part (22) are likewise shrunk on.

Abstract: One-part stabilizers are designed for road traffic only or for off-road travel only. Two-part stabilizers with a shiftable clutch have drawbacks in terms of quality and safety. A clutch is therefore presented, whose radial carriers (14, 16) are located on the same plane and which are fixed without clearance via a shiftable and axially displaceable locking piston (17) with locking elements (23) or are released over a predetermined pivot angle.

Abstract: Swivel motors have a large number of tightness problems on the inside, in particular in a broad operating temperature range. Therefore, to improve the tightness over a temperature range of ?40° C. to +130° C., a sealing device (20) is provided with an inner soft sealing element (20) and a plurality of outer rigid sealing elements (21, 22, 23, 24). The soft sealing element (20) and the rigid sealing elements (21, 22, 23, 24) are undetachably connected to one another. The circumferential sealing surfaces of the rigid sealing elements (21, 22, 23, 24), in the unloaded state, close flush with the sealing surface of the soft sealing element (20). The rigid sealing elements (21, 22, 23, 24) are spaced apart from one another by at least one radial compensating groove (25) and at least one axis-parallel compensating groove (26).

Abstract: To improve the surface finish of the inner circumferential surfaces of the stator and to reduce the manufacturing effort, it is proposed that the stator with a stator housing 1 and with the stator blades 13 have a two-part design and to insert the stator blade 13 into the stator housing 5 in such a way that they rotate in unison. In terms of the process, it is proposed that a commercially available tube with an inner circumferential surface suitable for use as a sealing surface be used and that longitudinally extending joining means be prepared. The stator blades 13 manufactured as an individual part receive corresponding joining means, so that the stator housing 5 and the stator blades 13 are welded, clamped or screwed together.

Abstract: A switchable stabilizer is provided as a compact assembly unit. The hydraulic system of the hydraulic and control part (9) may form a closed circuit with the piston-and-cylinder unit of the switchable coupling unit (3)and the hydraulic and control part (9) may be integrated in the cylindrical housing (10) of the switchable coupling (3).

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.

Abstract: Cams for clutches have been produced by a machining in a highly complex manner. To reduce the corresponding production costs, the cam (6) is first formed or deformed in such a way that the outer surface (13) has its finished measures and the cam journal (18) has an overlength. Mechanical machining is carried our, the finished outer surface (13) being used as an abutment for the clamping device. After the mechanical machining, the overlength of the cam journal (18) is twisted off.
