The link joint consists of two or more link arms and a connecting link pin. It has at least two calotte-shaped slide bearing surface pairs (23,24). At least one of the link arms (8,10), and a facing underside (22) of the link pin head (19) are also calotte-shaped (ball sockets 16). A bearing sleeve (18) having a concave or convex calotte- shape is moulded on an aperture (17) of one link arm. Both link arms are calotte-shaped, and are separated by a slide disc. |
