Abstract
A process is provided for manufacturing a ball and socket joint that has a ball pivot () that is composed of a pivot pin () with an essentially spherical ball head (4) arranged or made integrally in one piece on one side. A bearing shell () is provided as well as a preformed plastic film as a thin-walled ball socket () with a joint surface () enclosing the ball head at least partially. A lubricant () is introduced between the surface of the ball head () and the joint surface () of the thin-walled ball socket (). According to the process, the thin-walled ball socket () is filled first with the lubricant (). The ball head () of the ball pivot () is then introduced into the thin-walled ball socket () filled with lubricant (), and the ball head () provided with the thin-walled ball socket () is subsequently introduced into the housing (). Finally, the free space between the thin-walled ball socket () and the housing () is filled up with a material to form a bearing shell (). The ball and socket joint () is formed with a preformed plastic film as a thin-walled ball socket ().
