Reasonable shaft structure: The connecting rod shaft adopts an optimized I-shaped cross-section design, which effectively reduces its own weight while ensuring sufficient strength and stiffness. The I-shaped structure can effectively resist complex stresses such as tension, compression, and bending generated during engine operation, ensuring that the shaft is not easily deformed and maintaining stable power transmission during high-speed and high load operation of the engine. At the same time, the reduced weight helps to reduce the inertia force of the engine, improve the response speed of the engine, and make the vehicle's acceleration, shifting, and other operations smoother, with a tighter power connection.
Precise big and small head design: The connecting part between the connecting rod big head and the crankshaft connecting rod journal adopts high-precision aperture machining and surface treatment technology to ensure a tight fit and uniform gap with the bearing shell. This can not only reduce friction losses during operation, improve power transmission efficiency, but also effectively reduce noise and vibration. The connecting part between the small end of the connecting rod and the piston pin is designed with a thin-walled bronze liner, which is smooth and has good wear resistance inside. It can provide stable support for the piston pin during frequent reciprocating motion, reduce wear, extend the service life of components, and ensure the accuracy and stability of engine power transmission.
Strong load bearing capacity: When the engine is working, the connecting rod needs to withstand the huge gas explosion force transmitted by the piston and the reciprocating inertia force of the piston group, and the magnitude and direction of these forces undergo periodic and drastic changes. This engine connecting rod is made of high-quality high-strength materials, which have excellent fatigue resistance and yield strength. It can stably withstand alternating loads under harsh working conditions and is not prone to fatigue fracture and other problems, ensuring that the engine can still operate reliably under long-term high load operation, providing stable power for the vehicle.
Accurate motion transmission: The manufacturing accuracy of the connecting rod is extremely high, and the dimensional tolerances of each part are strictly controlled within a very small range. This enables the connecting rod to maintain precise motion trajectory and phase relationship while transmitting piston motion to the crankshaft. Whether the engine is in idle, low-speed driving, high-speed cruising, rapid acceleration and other different working conditions, the connecting rod can ensure the coordinated motion between the piston and the crankshaft, avoiding engine shaking, unstable power output and other phenomena caused by motion deviation, and improving the overall smoothness and stability of the engine operation.
High strength alloy steel material: The connecting rod body is made of high-quality high-strength alloy steel as the base material. This alloy steel has excellent comprehensive performance, not only possessing high strength and good toughness, which can effectively resist mechanical and thermal stress impacts during engine operation, but also excellent wear resistance. During long-term high load operation of the engine, the connecting rod frequently contacts and rubs against components such as piston pins, crankshaft connecting rod necks, etc. The high-strength alloy steel material can effectively resist wear, ensure the long-term stability of the connecting rod's structural dimensions, guarantee the accuracy and reliability of engine power transmission, greatly extend the service life of the connecting rod, and reduce maintenance and replacement costs.
Advanced surface treatment technology: In order to further enhance the performance and durability of the connecting rod, its surface has been specially treated. The surface of the connecting rod adopts advanced processes such as carburizing, quenching, and hard chrome plating, which significantly improves the surface hardness and wear resistance, while enhancing its corrosion resistance. The carburizing treatment forms a high hardness carburizing layer on the surface of the connecting rod, which improves the wear resistance and fatigue strength of the surface; The quenching process further refines the internal structure of the steel and enhances the comprehensive mechanical properties of the material; The hard chrome plating process forms a hard and smooth chrome layer on the surface of the connecting rod, which not only reduces the surface friction coefficient and energy loss, but also effectively prevents the connecting rod from being corroded in complex engine working environments, ensuring that the connecting rod maintains good performance during long-term use.
