An insert for a ball joint () in a motor vehicle. The insert having a first part-structure () for making at least partial slide-bearing contact with a joint ball (). The first part-structure () can be connected, by over-molding, to a joint socket () and/or to a joint housing (). The insert () can be positioned and/or handled to cover a pole surface, to increase the extraction force, the insert () has an open part-structure () such that a cage-like configuration can be produced for surrounding the joint ball ().

Insert for a ball joint in a motor vehicle, ball joint or link having an insert of this type, and method for producing an insert of this type, a ball joint of this type or a link of this type

A joint () with first and second joint components () are movably connected to one another. The first joint component () has a spherical joint body () and the second joint component () rotatably and pivotably holds the joint body (). A sensor device, for determining the position of the first and second joint components () relative to one another, is arranged on the joint (). The sensor device has at least one sensor element () which can be integrated in a housing () that is produced by an assembly overmolding process. The joint housing () forms the second joint component () in which the joint body () is directly supported.

Joint, link for a wheel suspension and method for assembling a joint

A chassis component for a wheel suspension which has a strut arrangement with at least one strut which is in the form of a profile component with an open cross-section. The at least one strut has a profile base and two wall sections that extend away from the profile base. An articulation point is provided, at least at one end of the strut, for receiving two joint components movably connected to one another, namely, a first joint component having a spherical joint body and a second joint component that rotatably and/or pivotably holds the joint body. In the area of the at least one articulation point, the wall sections have first and second joint accommodation apertures arranged opposite one another. A cylindrical sleeve is pressed in between the first joint accommodation aperture and the second joint accommodation aperture and keeps the opposite wall sections apart from one another.

Chassis component for a wheel suspension and method for producing a chassis component

A chassis component for a wheel suspension, having a strut arrangement with at least one strut which has a profile with an open cross-section. The at least one strut has a profile base and two wall sections which extend away from the base. An end of the strut has an articulation point that receives a first joint component having a spherical joint body and a second joint component which holds the joint body so as to rotate and/or pivot. A first joint accommodation aperture and a second joint accommodation aperture are arranged, in the area of the articulation point, opposite one another. The joint body is positioned via a circular-segment-shaped fastening element arranged on the joint body between the joint accommodation apertures. The joint accommodation apertures and the joint body positioned between them are integrated in a joint housing produced by overmolding, which forms the second joint component.

A method for producing a ball joint having an outer housing with an outer housing stud opening, an inner housing arranged inside the outer housing and provided with an inner housing stud opening, and a ball stud having a joint ball is moveably fitted in the inner housing and which extends out through the inner housing stud opening. The method includes inserting and positioning the stud with its joint ball in the outer housing such that, between the outer housing and the stud, a free space surrounding the joint ball and/or stud remains and the stud extends out through the outer housing stud opening. After which the free space is filled with a plastic material which enclosed the joint ball and then cures to form the inner housing. A gap is formed between the outer and inner housings during curing and closed after curing by compressing the outer housing.

Method for producing a ball joint

A sleeve joint (), in particular for a vehicle, having an outer sleeve () which receives and secures a ball socket (), in an axial direction. The ball socket () is composed of a plastics material for engagement with an inner ball joint body (). The ball socket () extends radially as far as an inner wall () of the outer sleeve, such that the ball socket () is supported directly on the outer sleeve ().
