Problems solved by technology

Fitting is usually done by knocking, so that the ball bushing rests on one side against the closing ring, which leads to premature wear of the ball joint, which leads to large play in the ball joint

Embodiment Construction

[0018] Fig. 1 shows a universal ball joint, which basically comprises: a ball joint neck 1, a ball joint socket 2, an integral or multi-part socket arranged in the socket 3 of the ball joint socket 2 Bearing sleeve 4, a closed ring 5 and a sealing sleeve 6 made of elastic material. The universal ball joint can be used, for example, in the automotive sector, in this case on the chassis or on the steering part of passenger cars and commercial vehicles. It can be used to achieve a controlled rotational movement and tilting movement between two parts, wherein the ball joint neck is fixed on a vehicle part with its free end protruding from the ball joint socket, which end has A cone 7 and a threaded fixed end 8 connected to the cone. Correspondingly, another movable part is fastened to the ball joint socket 2 by means of a fastening mechanism not shown in detail in the figure. At its end opposite the fastening end 8, the ball joint neck 1 has a spherical joint 9 which is seated i...

Abstract

The invention relates to a ball-and-socket joint comprising a pivot pin (1, 31) which is received in a bearing shell (4, 34) in a rotating and articulated manner with a spherical joint region (9, 39), said bearing shell being, in turn, arranged in a recess (3, 33) of a joint housing (2, 32). A closing ring (5, 35, 36) fixes the bearing shell (4, 34) in the joint housing (2, 32) in the axial longitudinal direction of the pivot pin (1, 31) by means of at least one surface pairing. According to the invention, an elastic intermediate element (20, 50) can be arranged between the corresponding bearing surfaces of the surface pairing (4, 34) of the closing ring (6, 36, 43) in a first mode of embodiment, or, in a second mode of embodiment, an insertion element (66) is arranged between the outer contour of the bearing shell (64) and the base region (72) of the recess (63), at least one elastic intermediate element (70, 71) being arranged between the outer surface of the insertion element (66) and the corresponding inner surface of the recess (63). In this way, the dimensional accuracy required for ball-and-socket joint components can be significantly reduced, thus reducing production costs.

Description

technical field [0001] The invention relates to a universal ball joint with a ball joint neck, which is accommodated rotatably and pivotally with a ball joint part in a bearing sleeve, which is seated in a recess of a ball joint socket, One of the closed rings fixes the bearing sleeve in the ball joint socket along the longitudinal axis of the ball joint neck and through at least one pair of joint surfaces. Background technique [0002] Ball joints of the above-mentioned type are known in various forms in the prior art, and they are used in particular in the chassis area and steering control area of ​​passenger cars and commercial vehicles. A criterion that has a decisive influence on the quality of the ball joints used here is their service life, which should be estimated to be sufficiently large even under increased load conditions. In this case, an important prerequisite for a sufficiently long service life is that the permissible tolerances of the components of the join...
