Abstract
Forged connecting rod, in particular of an internal combustion engine, including a body (1), a connecting rod small end (2) and a connecting rod big end (3), forming two connecting rod small end and connecting rod big end bearings for receiving respectively a piston pin and a crankpin. The connecting rod is constituted by two half connecting rods (5) which are substantially symmetrical relative to a longitudinal median plane (6) of the connecting rod, which plane contains the longitudinal axis of the connecting rod, the joint surface (9) of the half connecting rods being essentially disposed in the median plane (6), the half connecting rods (5), each of which has a connecting rod half bearing (7) and a connecting rod big end half bearing (8). Located on each side of the connecting rod small end and big end are serrations (10) which are formed on the joint surface (9) of the half connecting rods and fit into one another in a complementary manner, these serrations ensuring by their shape a locking against slip of the two half connecting rods (5) in the joint plane, in particular along the longitudinal axis of the connecting rod and along the axis of the crankpin and the piston pin si…
