ABSTRACT:
The invention pertains to a pivot joint with a housing (4) in which a ball pivot (1) is mounted via its ball race-shaped bearing surface (1a) by means of an inset bearing shell (3) to be free from play within a delimited range and, set against a restoring force, to be twistable and horizontally sweepable. In order to create the pivot joint, in which the defined restoring force of the spring (5), independent of respective tolerances, increases with deflection according to the spring characteristic and form, the ball pivot (1) is provided with an end surface (1b) located opposite pivot shank (2), and a conical countersink (7) extending to the edge is configured in this end surface (1b), in which the ball sits closely on the conical surface (7a) of this conical countersink (7), with the ball (6) being acted upon by the force of a spring (5) supported by the cover (8) which seals the housing (64).
