A sealing element for a ball joint has a sealing area on the housing side and a sealing area a distance away therefrom in an axial direction of the sealing element on the stud side. Arranged between the housing-side sealing area and the stud-side sealing area is an outlet opening which extends through the sealing element to allow the passage of spent lubricant. The outlet opening extends in the axial direction of the sealing element, passing all the way through the sealing element in the axial direction. Further, the sealing element is incorporated in a ball joint which is incorporated in a two-point control arm.

Sealing element for a ball-and-socket joint

A ball joint for a chassis component in the form of a two-point linkage. The ball joint includes a housing and a ball stud fitted and able to be deflected in the housing, as well as a sealing element arranged between the housing and the ball stud, which surrounds the ball stud all round. Deflection movement of the ball stud, relative to the housing, is restricted at least in some areas by the sealing element. The sealing element is attached to the housing by an interlocked connection. The sealing element of the ball joint is attached to the housing by a snap-on connection. A two-point linkage having such a ball joint, and the two-point linkage is a steering rod or a track rod.

Ball joint for a two-point link and two-point-link with such ball joint

A joint device () having an axially extending pivot pin (), in particular a so-termed claw, and an elastically deformable layer () that wholly or partially surrounds the pivot pin radially. The deformable layer is at least partially in contact on its radially outer side () with a housing () and is connected, such as by vulcanization at least at one axial end, with an annular body (). The pivot pin () with the elastically deformable layer () and the at least one annular body () form a joint body () which can move relative to the housing () and is designed, in such a manner, that the ability of the joint body () to rotate about its longitudinal axis () is inhibited by a rotation-impeding device () and by the contact of the outside () of the elastically deformable layer () against the housing.
