Method for producing a low-friction ball joint and a ball joint produced according to this method |
摘要 |
A process for manufacturing a low-friction ball-and-socket joint is provided in which a ball pivot with a pivot area and with a joint ball made in one piece therewith is first introduced into a bearing shell (2, 2.1, 2.2) and the latter is in turn introduced through an opening (4) into a joint housing (5), wherein the opening (4) of the housing (3) is closed by a housing cover (5) after the introduction of the components. The pivot area (1.1) of the ball pivot (1) is then introduced into a recording device of a torque measuring device to determine the torque of the joint between the bearing shells (2.1,2.2) and the joint ball (1.2). The housing cover (5) is then permanently fixed by a rolling device (10) by bending over a rolled edge (9) of the housing arranged on the housing (3). The torque of the joint is continuously measured during the rolling operation and is compared with a presettable set point. The housing cover (5) displaces the upper bearing shell (2.2) in the axial direction against the joint ball (1.2) and generates a pressing force, which is partially compensated by a support element (6) at the housing cover (5). The rolling process is immediately terminated when the set point of the torque of the joint is reached.
