ABSTRACT:
The invention is based on a pinless sheet-metal hinge with maintenance-free bearing for motor vehicle doors, comprising two hinge halves, each securable via hinge tabs to one of the two parts of the door arrangement and meshing with one another with their single-joint regions, at least one of which is shaped from a sheet-metal material blank and in its single-joint region has two regions parallel to one another and oriented perpendicular to the hinge axis; the two hinge halves are supported pivotably on one another about a hinge axis with the interposition of bearing bushes made of a maintenance-free bearing material. In order to facilitate production using fully automatic machines, the invention proposes the provision of leadthroughs, concentric to one another and to the hinge axis, on the single-joint regions parallel to one another of each of the two hinge halves; the leadthroughs from one hinge half to the other have different diameters, such that the leadthroughs of the two hinge halves can be inserted in the manner of a male and female plug part.
