Piston with two pivot bearings and twin crankshaft piston engine

A twin crankshaft piston engine with at least one piston cylinder unit, comprising:

• a cylinder in which a reciprocating piston is disposed, so that it can move back and forth;
• a first crankshaft;
• and
• a second crankshaft,
• wherein the first crankshaft and the second crankshaft extend parallel to one another and rotate synchronously in opposite directions,
• wherein the rotation axes of the two crankshafts extend parallel to a common cylinder center plane and are laterally offset with respect to the cylinder center plane, wherein a first and a second connecting rod is associated with the reciprocating piston, so that
• the first connecting rod is pivotably supported with its first end at the reciprocating piston in a first pivot bearing about a first connecting rod pivot axis and rotatably supported with its second end at a crank pin of the first crankshaft;
• and
• the second connecting rod is pivotably supported with its first end at the reciprocating piston in a second pivot bearing about a second connecting rod pivot axis and rotatably supported with its second end at a crank pin of the second crankshaft, and
• wherein the first and the second pivot bearing are provided at a bearing element which is pivotably supported at the piston about a bearing element pivot axis which extends parallel to the connecting rod pivot axes.
