摘要
Ball joint comprising a housing (2), a joint ball (3) disposed in the interior space of the housing (2) and which is part of a ball pin (3a), and a socket joint (4) arranged between these two and which is applied on its outer surface (7) to the inner surface (6) of the housing and its inner surface (8) to the surface (5) of the ball joint, in which the cup joint ( 4) receives the joint ball (3) with mobility sliding and is of such elastic construction that, in the presence of an actuating force (11) on the ball joint (1), the joint ball (3) can be movable relative to the housing (2), and wherein the cup joint (4) in a transverse plane of section passing through the center (18) of the patella, perpendicularly to a vertical axis coinciding with an axis longitudinal housing (2), the longitudinal axis along the longitudinal axis of symmetry and being located pi vote joint (3a) in an undeflected state of the ball joint, has an inner circular contour (22) and an outer contour (12) configured in this manner, wherein in the cross-sectional plane the bowl patellar (4) is constructed in the region of a shaft main load (9) with a greater thickness than in the orthogonal transverse axis (10) thereto, and wherein the transverse axis (10) subdivides the outer contour (12) in first and second partial segments, characterized in that the outer contour (12) of the cup joint (4) is formed in at least one of its two subsegments by a first part-circle and a second partial circle ( fifteen; 16) intersecting at two cutting points (20, 21) symmetrical with respect to the axis of main load (9), the center (17) of the first partial circle (15) being disposed eccentrically relative to the center (18 ) of the patella and being located on the axis of main load (9), and corresponding radius of the first partial circle (15) the radius of the ball joint, and the center of the second partial circle (16) concentrically it is disposed with relative to the center (18) of the patella and the radius of the second partial circle (16) greater than the radius of the ball, whereby the cup joint (4) has at least in the cross-sectional plane a radial thickness varying in the circumferential direction such that a force (11) acting coaxially to the axis of main load (9) is evenly distributed in the circumferential direction of the cup joint (4) along an angular range (13).
