Connecting rod for an internal combustion engine with variable compression

A connecting rod for a variable compression internal combustion engine, the connecting rod comprising:

• a crank bearing eye configured to connect the connecting rod to a crankshaft of the variable compression internal combustion engine;
• a connecting rod bearing eye configured to connect the connecting rod to a cylinder piston of the variable compression internal combustion engine;
• and
• an eccentrical element adjustment arrangement configured to adjust an effective connective rod length, which eccentrical element adjustment arrangement includes an eccentrical element that is connected torque proof with an eccentrical element lever,
• wherein the eccentrical element adjustment arrangement includes two hydraulic chambers respectively including a piston that is movably arranged in a cylindrical borehole and connected with a support rod which is connected with the eccentrical element lever at another end,
• wherein the support rod is configured from plural components,
• wherein the support rod is configured as an assembled support rod,
• wherein the support rod includes a rod element with a pivot link element arranged at one end and a piston connector arranged at another end, and
• wherein the rod element is connected with the pivot link element and the piston connector by a friction weld,
• wherein the piston connector is configured as a ball,
• wherein the rod element is configured as a tubular rod element,
• wherein the pivot link element is configured as a tubular sleeve whose longitudinal axis is configured perpendicular to a longitudinal axis of the tubular rod element, and wherein the tubular sleeve is welded to the tubular rod element by a friction weld,
• wherein the link element includes an impressed bearing bushing.
