BALL JOINT WITH WEAR TESTING

A ball-and-socket joint, preferably for vehicle suspensions or steering mechanisms of motor vehicles, has a joint housing and a pivot pin, which is mounted rotatably and deflectably in a spherical bearing surface via a one-part or multipart bearing shell. The bearing shell itself is fixed in the joi...

Beschreibung
Zusammenfassung:	A ball-and-socket joint, preferably for vehicle suspensions or steering mechanisms of motor vehicles, has a joint housing and a pivot pin, which is mounted rotatably and deflectably in a spherical bearing surface via a one-part or multipart bearing shell. The bearing shell itself is fixed in the joint housing. The joint housing or the pivot pin is fixed against the vehicle suspension in an electrically insulated manner, in which the joint housing (1) and the pivot pin (2) are connected according to a potential difference-measuring unit (13) via electrical contacts (12, 14). The spherical bearing surface of the pivot pin (2) and its corresponding opposite surface in the joint housing (1) are electrically insulated against each other. The state of wear of a ball-and-socket joint can be determined and the user of the motor vehicle can obtain an indication of the end of the service life of the ball-and-socket joint and the necessary repair in time.
