A ball and socket joint () is provided, for example, for a chassis bearing, with a ball (), a pivot () originating from the ball (), a housing () accommodating the ball, and a sealing bellows (), which extends between the housing () and the pivot () and has a housing-side opening () and a pivot-side opening (). The sealing bellows () has a circumferential sealing lip () for sealing at the pivot-side opening (). The ball and socket joint () has a first guide ring (), which guides the sealing bellows (). The first guide ring () is arranged at the pivot (). An especially favorable functional separation is achieved as a result between the guiding function and the sealing function.

Ball and socket joint with sealing bellows

A process for controlling the shrinkage behavior during the original shaping of plastics during the manufacture of a plastic shell, especially a bearing shell for a ball-and-socket joint, wherein liquefied plastic is introduced between an inner mold () and an outer mold () in order to be cured therein, wherein the plastic is partially fixed on the outer mold () during the curing. This process can be preferably used in a device for controlling the shrinkage behavior during the original shaping of plastics, which has a casting mold, which accommodates at least one outer mold () and an inner mold () inserted into same, wherein the liquefied plastic () to be molded can be introduced between the mold parts (), wherein means for fixing the liquid plastic () are formed on the outer mold ().

Method and device for controlling the shrink behavior of plastic materials during primary shaping

A ball-and-socket joint has a housing, a ball pivot () mounted pivotably in the housing, and a sealing bellows (), which is fastened to the housing and is mounted on the ball pivot () slidably via a sealing ring () provided with two legs (). A first leg () of the two legs () is in contact with the ball pivot () under tension and the second leg () meshes with the wall of the sealing bellows (). The second leg () is, furthermore, fastened in an anchoring ring () arranged at least partially in the wall of the sealing bellows ().

Ball- and -socket joint

A ball-and-socket joint, especially a wheel guide joint for motor vehicles is provided with a housing (), in the cavity () of which, which is open on at least one side, a bearing shell () is inserted with a joint ball () mounted therein. The bearing shell () forms a assembly unit () together with the joint ball () accommodated therein. The assembly unit is displaceable in the cavity () along a axis (). A first collar () and a second collar (), between which a limited free path () of the displaceable assembly unit () is defined, form end stops in the cavity () of the housing (). The bearing shell () is a accomodated in the cavity () under a slight radial pretension and at least one compensating element () is arranged between the bearing shell () and the inner surface of the cavity ().

Ball joint

A joint () with a joint housing () and with a joint shell () is arranged therein with a ball () having a pivot pin () protruding from the joint housing () and surrounded by a rubber bellows () with a protective cap (). A ring () for holding the protective cap () is connected to the edge area () of the rubber bellows (). The edge area () concentrically surrounds the pivot pin (). The ring () has a circular bead (8) on its annular outer side () and is vulcanized into the edge area () of the rubber bellows (). The protective cap () is provided on its inner side () with a plurality of projections (), which can be bent from the outside through openings () in the protective cap () by means of a tool () radially (arrow) in relation to the pivot pin () against the bead () of the ring () in a non-positive and positive locking manner.

Joint, particularly a ball-and-socket joint for chassis parts in a motor vehicle

A ball-and-socket joint for motor vehicles has a ball pivot with at least a joint ball () accommodated rotatably and/or pivotably in a bearing shell () of a housing () and a pivot section (). A sealing bellows is provided with a first edge area () fastened to the housing () and withe a second edge area () has a sliding connection with a thrust ring (), which is fixed on the pivot section () and comprises an axial shoulder () and a radial shoulder (), wherein the radial shoulder () of the thrust ring () forms a wave-shaped contour.

Ball joint for motor vehicles

A ball-and-socket joint for motor vehicles is presented, which has a ball pivot (), which comprises at least one joint ball () accommodated rotatably and/or pivotably in a bearing shell () of a housing (), and a pivot section (). A sealing bellows (), whose first edge area () is fastened to the housing () and whose second edge area () has a sliding connection with a thrust ring () fixed on the pivot section (), is used to seal the joint components. A protective cover (), which is used to seal the thrust ring area as well as for shielding against damaging heat radiation and against the effects of splash water or corrosive media, is inserted between a surface of the thrust ring () and the surface of a motor vehicle component (), which said surface faces the said surface of the thrust ring.

Ball and socket joint for motor vehicles

An apparatus and method for motor vehicle suspension arms or subframes is provided. A motor vehicle apparatus and method is used with frame components. The motor vehicle component includes frame parts of lightweight design that have complementary profiles that can be inserted one another to create a locking connection between the frame parts. The invention frame parts may be designed as extruded profiles. The motor vehicle component allows for the individual frame parts to be manufactured separately from one another and combined wherein the number and cross section of the stiffening ribs are selectable in a load dependant way in the form a modular system and different materials may be used for individual components.

Automobile component

A radial ball-and-socket joint is provided with a housing. A bearing shell ( ) in the housing rotatably and tiltably accommodates a joint ball ( ). The joint ball is part of a ball pivot ( ). The ball pivot also has a shaft ( ), which projects through a outlet opening ( ) of the housing ( ). The housing is closed with a cover ( ) on the side opposite the outlet opening ( ). The bearing shell ( ), accommodated in the housing in a positioned manner, has an axially extending continuous slot ( ). The cover ( ), arranged between the cover and the bearing shell, has a geometry ( ) impressed into a damping element ( ) on its inner side facing the bearing shell. As a result of the construction the damping element ( ) and the bearing shell are fixed in the housing ( ).

Radial ball joint

Composite part containing metallic foam and method for producing said composite part

A bellows seal ( ) on a ball-and-socket joint provided with joint ball and ball pivot ( ), especially on a ball-and-socket joint of a chassis bearing, with an elastic bellows has a pivot-side opening and a joint-side opening and axially surrounds the ball pivot ( ) of the ball-and-socket joint. A circumferential, elastic and outwardly pointing sealing lip ( ), which can be in contact with a sealing surface ( ), is provided at the pivot-side opening of the sealing bellows ( ). An L-ring, whose first leg ( ) points essentially in the axial direction (axial leg) and whose second leg ( ) points radially to the outside (radial leg), is provided at the pivot-side opening. The radial leg ( ) engages a groove extending on the inside of the sealing bellows ( ) or is anchored in it, and the inside of the axial leg ( ) is sealingly in contact with an opposite running surface.
