Problems solved by technology

[0005] In this solution, however, it was found to be disadvantageous that the originally cylindrical housing deforms until it deforms into an area against which the edge part of the sealing bellows rests after the ball joint has been produced
This can lead to a threat to the permanent tightness of the sealing bellows and thus raises concerns about ingress of moisture and dirt into the internal joint parts

Embodiment Construction

[0063] exist figure 1 , the completed installed ball joint is shown in cross-section. The housing 1 has a radially protruding shank 22 by means of which the housing 1 can be fastened to a corresponding component of the motor vehicle. Existing cavity 4 in housing 1 (this cavity is in Figure 4 or Figure 5 (can be seen more clearly in ), a bushing 13 is embedded in which, with its outer peripheral surface, rests directly on the housing inner contour 28 of the inner chamber 4 over a wide area. In this embodiment of the ball joint, the housing inner contour 27 has a bevel, on which the bushing 13 is supported with a corresponding bevel. The bushing 13 , which is made of plastic and has limited elasticity, accommodates the joint ball 2 of the ball pin 3 with its in this case spherical inner peripheral surface. exist figure 1 In the illustration of , the ball pin 3 is shown in the non-deflected position. Starting from the joint ball 2 , the ball pin 3 transitions into a pin s...

Abstract

The invention relates to a ball joint having a housing (1) produced overall by a cold forming method, comprising an interior space (4) that is adapted for mounting the joint ball (2) of a ball pin (3) and, on one side, comprising an opening (5) for passing through the pin section (6) of the ball pin (3) connecting to the joint ball (2), a contact region (7) present on the outer lateral surface of the housing (1) for sealingly fastening a bellows seal edge (8), and a deformation section (9) of the housing (1) for the rotatable and pivotable fixation of the joint ball (2) of the ball pin (3) in the interior space (4). According to the invention, the material displaced during the cold forming process forms the deformation section (9) of the housing (1) after the housing (1) is finished. The claimed method for producing a ball joint is characterized by the following steps: - producing a metal housing blank (25) having a thickening (26) integrally formed by way of upsetting, - configuring the housing outer contour (27) by way of upsetting, - forming the housing inner contour (28) by way of can extrusion, wherein the displaced material is used in particular for configuring the deformation section (9).

Description

technical field [0001] The invention relates to a ball joint as well as to a method for producing a ball joint housing and a method for producing such a ball joint. Background technique [0002] From DE 195 36 035 A1, which forms the preamble, a method for producing a housing of a ball joint, in particular for a tie rod of a motor vehicle, and a ball joint produced by means of this method are known. shell. The housing has an inner cavity which fits a ball joint for supporting the ball pin. The housing, which is initially open on both sides, is then closed on one side by a cover, wherein a profiled section is provided on the upper edge of the housing for fastening the cover. After the ball pin has been inserted into the housing interior together with the bushing bearing the joint ball, it is closed by means of a cover. A pin section of the ball pin protrudes from the opening on the side opposite the cover. In this case, a sealing bellows is provided for sealing the inner ...
