发明名称 Ball joint
摘要 The invention pertains to a ball joint, having a ball joint socket (1), inside of which the ball (3c) of a ball-ended spindle (3) is arranged in a rotatable and tiltable manner by means of a bearing shell (2) that supports the ball (3c) below its largest diameter on a bearing surface that has the shape of a ball race, namely under the influence of spring force generated by a spring element (4) that simultaneously forms the upper bearing shell and is supported on the underside of a cover (5) that closes the ball joint socket (1). In order to entirely eliminate all manufacturing tolerances during assembly of the ball joint and provide defined spring forces that compensate for the wear-related elasticity of the ball joint until a defined wear is reached after assembly, the cover (5) which is realized in such a way that its outer diameter exceeds the inner diameter of the ball joint socket (1) in the initial state is nonpositively supported in the ball joint socket (1) with its edge (5c). The spring element (4) is exclusively supported in the center of the cover (5) by means of spring tabs (4a) that point toward the center and transform into a cylindrical center part (4b) at their outer edge, with a marginal region (4c) that has the shape of a ball race and adjoins the surface of the ball (3c) situated adjacent to the cylindrical center part.
