PISTON ASSEMBLY HAVING OFFSET BEARING

摘要

A piston assembly is disclosed for use with an engine (10). The piston assembly may include a first and second piston crown (45) and a first and second connecting rod (14). The first and second connecting rods may each have a first end (24) pivotally connected to the first and second piston crowns, respectively, and a second end (26) with a circular opening configured to receive a throw (11) of a crankshaft (16). The second connecting rod may have a running surface (34) defining at least two outer lands (29)and at least one inner land (31) disposed between the at least two outer lands that alternately support a load of the second piston crown. The piston assembly may further include a bearing (28). Both the inner and outer lands may simultaneously support the load of the second piston crown against the bearing at a point of highest load on the second piston crown.
