BEARING BUSHING FOR A CONNECTING ROD COMBINATION OF A CONNECTING ROD AND A BEARING BUSHING AND METHOD FOR PRODUCING SAME

摘要

The invention relates to a bearing bushing (12) for a connecting rod (1) and to a combination of a connecting rod and a bearing bushing. The connecting rod (1) has a small end (2) which comprises a bearing bore (3), in particular for receiving a pin (36) of an engine piston (37) of an internal combustion engine. A first region of (6) the bearing bore, which in operation is subjected to compressive loading, is longer than a second region (7) of the bearing bore which is subjected to tensile loading. In order to modify a bearing bushing and a connecting rod so that with simple production and optimised weight the connecting rod comprises good bearing properties for the piston pin, according to the invention the bearing bushing (12) already has, before insertion thereof into the bearing bore (3) , a shape adapted to the end edge contour (9) of the bearing bore (3), wherein the first region (17) of the bearing bushing (12) is likewise longer than the second region (18) thereof. A method of producing such a small end is also disclosed.
