Abstract:
Process for the production of a ball joint connection between a sliding shoe (10) and a cylinder piston (1) of a piston engine with the following process steps:forming a spherical, dome-shaped recess (2) on the cylinder piston (1), or on the sliding shoe (10), and optionally forming the spherical dome shaped recess (2) on both the cylinder piston (1) and the sliding shoe (10), wherein the dome shaped recess (2) is undercut in such a way that the dome-shaped recess (2) comprises a solid angle region (a) of more than 180Â° and the diameter (D) in the region of the equator plane (5) of the dome-shaped recess (2) is greater than the opening diameter (d) of the dome-shaped recess (2), forming a spherical ball head (11) on the sliding shoe (10), or on the cylinder piston (1), and optionally forming the spherical ball head (11) on both the sliding shoe (10) and the cylinder piston (1), and pressing the ball head (11) into the dome-shaped recess (2), wherein an edge region (6) surrounding the dome-shaped recess (2) is elastically deformed when the ball head (11) is pressed in and engages the domed shaped recess (2), wherein the edge region (6) surrounding the dome-shaped recess (2) is provided with radial slits (20a) to facilitate the elastic deformation.
