Abstract
A connecting rod for an internal combustion engine includes a body, a first end and a second end which is larger than the first end. This forms two bearings at the first and second ends, and each receives a piston shaft and a crank shaft pin. The connecting rod is comprised of two parts, approximately symmetrical with respect to a longitudinal median plane of the connecting rods. Their joint surface is essentially arranged in the median plane. The parts each carry a half-bearing of the first end and a half-bearing of the second end, and they are connected to one another by at least one immobilization device. The connecting rod is characterized in that the immobilization device, located outside the connecting rod on the side of the first end of the connecting rod and outside the axis of a piston, is comprised of an articulation whose elements, identical on each part of the connecting rod, will extend beyond the plane defined by the joint surface and will have a thickness approximately equal to half the thickness of the connecting rod. The elements are installed opposite one another and the friction surfaces of the articulation are arranged perpendicular to the longitudinal axis of the connecting rod bearing. The elements of each of the two parts are held together by an assembly device.
