  • Patent number: 9541124
    Abstract: A ball joint, in particular, an axial joint, having a ball stud, which is enclosed in a ball socket. The ball socket is enclosed in a joint housing and is integrally formed having at least one spring element in a region of the ball socket that faces away from the opening of the joint housing. The spring element has discontinuities, in particular in the form of slots, so that wear compensation is created by the spring element within the ball joint.

  • Patent number: 6554525
    Abstract: A radial ball-and-socket joint is provided with a housing. A bearing shell (2) in the housing rotatably and tiltably accommodates a joint ball (4). The joint ball is part of a ball pivot (3). The ball pivot also has a shaft (5), which projects through a outlet opening (6) of the housing (1). The housing is closed with a cover (7) on the side opposite the outlet opening (6). The bearing shell (2), accommodated in the housing in a positioned manner, has an axially extending continuous slot (8). The cover (7), arranged between the cover and the bearing shell, has a geometry (9) impressed into a damping element (11) on its inner side facing the bearing shell. As a result of the construction the damping element (11) and the bearing shell are fixed in the housing (1).

  • Patent number: 6213675
    Abstract: An axial joint and a process for manufacturing an axial joint are described. The axial joint comprises a metallic housing (1) with an opening (2) and with an interior space (9), with a ball pivot (3), which has a joint ball (4) and a pivot pin (5). The joint ball (4) is surrounded for the most part by the housing (1) and a pivot pin neck (5.1) of reduced diameter compared with that of the pivot (5) is present in the transition area between the joint ball (4) and the pivot pin (5), and the pivot pin (5) projects through the opening (2) of the housing. The axial joint also has a bearing shell (6; 6.1, 6.2), which consists essentially of plastic and is arranged between the housing (1) and the joint ball (4), and the metallic housing is made in one piece.
