TWO-LINK PISTON-CRANK MECHANISM FOR INTERNAL COMBUSTION ENGINE Russian patent published in 2018 - IPC F02B75/32 F02B75/04 F16C7/02 F16C9/02 

FIELD: motors and pumps.

SUBSTANCE: invention relates to a multi-link piston-crank mechanism for internal combustion engine. Multi-link piston-crank mechanism comprises lower link (7) having one end face, to which input load (F1) is applied due to the combustion load. Lower link comprises forked section (13) with protruding fragments on one end face and forked section (14) with protruding fragments on the other end face, which are positioned on both sides of connecting rod bearing section (12). Forked section with protruding fragments on one end face accommodates the other end of upper link (8). Forked section with protruding fragments on the other end face accommodates the other end of control rod (9). Thickness of central section (12a) for connecting rod bearing section (12) in the axial direction of the crankshaft is greater in the section positioned on one end face of lower link (7), than in the section positioned on the other end face of lower link (7). Thickness of other end section (32) of the control rod exceeds the thickness of other end section (24) of the upper link.

EFFECT: multi-link piston-crank mechanism is proposed.
