Jingqiang Connecting Rod

F5500 Expansion-Clamping Connecting Rod Assembly

The split‑type connecting rod assembly is a core transmission component for high‑end internal combustion engines, manufactured using an advanced split‑fracture machining process. The big end of the connecting rod is pre‑stressed with controlled stress grooves to achieve a precise split; the resulting fracture surface features an interlocking, serrated structure. This ensures tight mating between the rod body and the cap, high positioning accuracy, superior fatigue strength, stable operation, and reduced noise. Produced in-house by Nangong Jingqiang Connecting Rods—a specialized, refined, distinctive, and innovative “Little Giant” enterprise—the product is certified to the IATF 16949 automotive quality management system. It is compatible with passenger cars, commercial vehicles, construction machinery, and agricultural‑machine internal combustion engines, supporting both mass‑production supply and custom design‑based development, thereby providing OEMs with a stable and reliable connecting‑rod solution.

The small end of the connecting rod houses the piston pin, thereby linking the piston to the rod. The rod body is typically designed with an I‑shaped or H‑shaped cross‑section to minimize weight while meeting strength and stiffness requirements. The big end of the connecting rod connects to the crankshaft’s connecting‑rod journal. It is usually of a split design; the half that is separated from the rod body is called the connecting‑rod cap, and the two parts are fastened together by connecting‑rod bolts.

The Great Wall comes standard with a 2.0‑liter split‑forged connecting rod assembly.

The crankshaft–connecting rod mechanism is the primary motion system of an engine. Its function is to convert the reciprocating motion of the piston into the rotational motion of the crankshaft, while also transforming the forces acting on the piston into torque delivered by the crankshaft to drive the vehicle’s wheels. The crankshaft–connecting rod mechanism comprises components such as the piston assembly, the connecting rod assembly, and the crankshaft–flywheel assembly.

The connecting rod consists of three parts: the portion connected to the piston pin is called the small end; the portion connected to the crankshaft is called the big end; and the section linking the small and big ends is known as the rod journal. The rod head typically features a thin-walled, annular structure. To minimize wear between the rod head and the piston pin, a thin-walled bronze bushing is press-fitted into the small-end bore. Holes or grooves are drilled or ground in both the small end and the bushing to allow splashed oil to reach the mating surfaces of the bushing and the piston pin.
