A hinge assembly for a vehicle track, conveyor chain or the like has at least one bearing lacquer coated onto at least one of the mutually contacting surfaces of the pin or bushing and having a binder or carrier of the polyamide/polyimide type or of a molecular structure with alternating amide and imide monomers. A filler of molybdenum disulfide, molybdenum oxides and/or hydroxides and graphite is provided in the carrier or binder. Other lubrication is not required and the bearing lacquer has a long life.

Hinge assembly for vehicle tracks and the like

A rotatable drive/support element having a support surface is used with a chain link having a hardened running surface extending in and adapted to ride in a travel direction on the support surface and a side surface also extending in the travel direction and normally out of contact with the element. The running surface has a predetermined width b and is formed of at least one edge region of an outwardly convex arcuate shape seen in the travel direction having a radius R of curvature and a respective corner region extending from the edge region to the side region and of an outwardly convex arcuate shape seen in the travel direction having a radius r of curvature. Herein r/b&cong;0.05 to 0.11, and preferably R/b&cong;2.4 to 3.1.
