Abstract:
1. A unit assembly system comprising: at least one exhaust gas turbocharger hydrodynamic axial plain bearing for supporting axial forces of at least one of a turbine wheel and a compressor wheel on a housing, said axial plain bearing having an axis of rotation of a shaft supporting at least one of the turbine wheel and the compressor wheel; and a plurality of wedge-shaped bearing segments all attached to one bearing body and distributed in a circumferential direction, wherein the bearing segments work together with at least one level, annular thrust surface extending transversely to the axis of rotation, wherein the unit assembly system includes different exhaust-gas turbocharger types, wherein the types differ from one another by at least differing loads of the at least one axial bearing, wherein different thrust elements having the respective thrust surface, and wherein at least one thrust element differs from another by having thrust surfaces of different radial sizes that all fit into an installation space that extends radially beyond the thrust elements that differ from one another; wherein respective thrust surfaces are configured on respective thrust elements to define an external diameter that is smaller than an operative external diameter of the bearing segments.
