  • Patent number: 6334620
    Abstract: The invention relates to a bellows seal for pivot joints, wherein a first end of the bellows is tightly and rigidly connected to the joint housing. The second end of the bellow tightly and annularly surrounds a tappet and has a radial and sealing surface. Said surface is a front face divided into an inner concave ring surface and an outer concave ring surface. In relation to the axis of the bellow, the angle of inclination of the ring surfaces is approximately &agr;=70° for the external ring surface and approximately &bgr;=80° for the inner ring surface. The radial extension of the outer ring surface is approximately 12% in relation to the radius of the outer ring surface of the ring flange of the second end of the bellow.

  • Patent number: 4921368
    Abstract: To seal a ball joint, a sealing bellows (3) with a bead (6) is fastened to the joint housing (1). The bead (6) is located in an L-shaped recess (4) of the joint housing (1) and is partially enclosed by an outer annular portion (8) of a retaining ring (5) deformed radially inward while an inner circular portion (7) of the retaining ring (5) engages an end surface (8) of the recess (4). To fix the sealing bellows (3) to the housing (1) in a single work step, there is machined in a cylindrical surface (12) of the L-shaped recess (4), a ring groove (11) which is engaged by an inner edge portion (10) of the inner circular portion (7) of the retaining ring (5). A tool (14) with a conical surface (15) is used for deforming of the retaining ring (5) which is advanced axially against the retaining ring (5), and the latter encloses the bead (6).

  • Patent number: 4812073
    Abstract: Method and apparatus for fastening of a sealing bellows (3) to a ball joint housing (1) in motor vehicles wherein the sealing bellows (3) has a housing end rim (16) that engages an approximately cylindrical bellows seat (11) formed on the outer rim of the joint housing defining an opening (10) through which a shank extends, and a retaining ring (5) made of sheet metal and surrounding the housing end bellows rim (16) for sealingly connecting the bellows to the housing, has an outer circumferential recess (17), is slipped onto the housing end bellows rim (16), and is then axially compressed so that its inner diameter is reduced, whereby the housing end bellows rim (16) sealingly engages the bellows seat (11) on the joint housing (1).

  • Patent number: 4755078
    Abstract: A sealing bellows for closing an opening in a ball joint housing said sealing bellows having axially extending hose sections continuously folded on each other, at least partially overlapping each other, and connected with each other by circumferential, contiguous, inner and outer folds; said hose sections beginning from the hose section attached to said housing having a progressively smaller diameter, and each outward fold having an axial thickening of material that exceeds that of an inner fold and the wall thickness of a hose section; said axial thickening shielding at least partially a hose section connected to the respective outward fold and having a smaller diameter.

  • Patent number: 4549830
    Abstract: The subject of the invention is the fastening of a sealing bellows to the joint housing of a ball joint, in which the housing-side rim of the sealing bellows is laid firmly into a ring groove circumscribing the joint housing, designed substantially U-shaped in cross section, the bellows rim having a profiling adapted to the U-shape of the ring above and being pressed into the ring groove by a clamp ring. To increase the sealing effect, it is proposed that the profiled zone of the bellows rim lying opposite the bottom of the ring groove forms, when drawn on by the tension ring, a fold lifting off from the bottom of the groove, arched upward, which stretches under the pressure of the clamp ring to force the bellows rim against the side walls of the groove.
