摘要:
A ball and socket joint is provided for a motor vehicle that has a joint housing (1), in the interior space of which a ball shell (2) is arranged. The ball (3) of a ball pivot (4) is accommodated in the ball shell (2). A sensor device (7), for measuring forces and loads, is arranged on a flexurally elastic printed circuit board (6). The printed circuit board is fastened in the joint housing (1) in a flexurally mobile manner. The sensor device (7) measures deflections and mechanical stresses of the sensor printed circuit board (6). A transmission device introduces forces or a bending moments into the sensor printed circuit board (6) in case of a deformation of the ball shell (2). The process makes possible the permanent determination of the state of wear of the ball and socket joint via measurement of the prestressing force of the ball shell.
