  • the defined pressing force can bring about a defined preload of the bearing shell, in which, in contrast to the prior art, the statistical characteristics are not determined by the manufacturing tolerances of the individual parts and optionally by a forming process of the housing, but by the defined pressing force during the assembly process for the closure element. Due to the geometric design of the individual parts and the defined adjustable pressing force, the static characteristic values can be set specifically with the smallest scatter of the values.
  • fixation of the closure element by means of a cohesive joining process offers the guarantee that the installation position predetermined by the pressing force is not subject to any changes during the fixing process for the closure element.
  • Cost reduction as a result of possible larger manufacturing tolerances and lesser rework and also allows the use of single or multi-part spherical shells made of high-strength plastics with low tendency to stretch, which in turn increases the life expectancy of the so designed ball joints.

  • the deformation of the joint housing can be designed as a circumferential retaining lug encompassing the outer contour of the closure element.
