A ball and socket joint for a motor vehicle is provided with a ball pivot (), which is accommodated rotatably and pivotably in a one-part or multipart bearing shell () fixed by a closing ring () in a housing (). A metallic deformation element (), which assumes a sealing function in the assembled state of the ball and socket joint, is arranged between the closing ring () and the housing (). The deformation element () is elastically deformed during the assembly of the ball and socket joint and is arranged at the housing () and/or at the closing ring ().

Sealing element for a ball and socket joint

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

The present invention pertains to a ball-and-socket joint, especially for steering mechanisms and/or wheel suspensions of motor vehicles, with a ball pivot (), which is accommodated rotatably and tiltably in a one-part or multipart bearing shell () within a joint housing (), wherein the bearing shell () is fixed in the joint housing by a closing ring (), wherein a metallic compressible element (), which provides a sealing contact surface between the joint housing () and the closing ring () in the assembled state of the ball-and-socket joint, is arranged between the closing ring () and the joint housing ().

Balljoint

A bearing shell for ball-and-socket joints or ball sleeve joints is provided with an inner hollow spherically designed bearing surface ( ). The bearing shell has an outer cylindrically designed support surface with which the bearing shell can be inserted into a joint housing. The bearing shell has a multipart design with at least two shell parts ( ), which can be detachably coupled with one another by a clamping device ( ). The parting plane between the half shells extends in the direction of the central longitudinal axis ( ) of the bearing shell.

Bearing shell for ball-and-socket joints

A ball sleeve joint with a joint housing has a ball sleeve provided with a preferably spherically designed bearing surface. A bearing shell surrounds the bearing surface and is accommadated in a recess of the joint housing. The joint housing is formed from at least two housing parts. The housing parts have corresponding elastic toothed elements. The toothed elements are locked with one another in the assembled state of the joint housing.
