Abstract
A supporting joint having a casing and a ball pin held therein comprises, on the pin side, a support having a bearing shell and, oppositely to the pin, a pressure shell. A cutout is provided in the central region of the pressure shell. On the rear side the pressure shell is provided with a cover having a support surface. Referred to the installed joint, the thickness of the pressure shell in a central support region, measured in the uninstalled state, is greater than the distance between the ball and the support surface of the cover.
Claims2
A supporting joint having a casing, a ball pin and ball held in the casing by a support comprising a shell-shaped receptacle, oppositely to the ball pin a pressure shell having, in an uninstalled state, a curved surface facing the ball immediately adjacent a cutout in a central support region thereof, and on a rear side relative to the pressure shell, a cover supporting the pressure shell and having a curved support surface in the central support region corresponding substantially to a curvature of the ball, wherein the thickness of the pressure shell in the central support region, measured in the uninstalled state of the supporting joint, is greater than a distance between the ball and the support surface of the cover so as to form a wedge-shaped zone in an installed state, wherein radially outwardly, relative to the pressure shell, the distance between the ball and the support surface of the cover exceeds the thickness of the pressure shell.
