A ball and socket joint has a sealing bellows ( 4 ) that is in contact with the surface ( 17 ) of the ball pivot ( 3 ) by means of a circumferential closing collar ( 11 ) in the shaft area ( 7 ) of the ball pivot ( 3 ). The ball and socket joint has an element ( 14 ), which is elastic in the axial direction of the pivot and may be designed as a compression spring element, arranged in the neck area ( 8 ) of the ball pivot ( 3 ). The compression spring element is supported with one end in the area of the transition between the neck area ( 8 ) and the ball ( 9 ) of the ball pivot ( 3 ) and with the other end indirectly or directly at the pivot-side closing collar ( 11 ) of the sealing bellows ( 4 ). The sealing bellows is permanently and reliably prevented from slipping off from the neck of the ball pivot even under extreme climatic conditions or in case of extraordinary mechanical stresses, for example, in case of exposure to the water jet of a high-pressure cleaner. In addition, the pivot-side seal of the sealing bellows as well as the control of the seal in terms of design and the dimensionability of the seal are improved. |
