Technological Innovations in High-Strength Connecting Rods for Construction Machinery
2026-04-28 18:54
As a key component of engine power transmission, connecting rods need to withstand the huge impact force generated by the reciprocating motion of the piston, and their strength directly affects the service life of the engine. The new generation of connecting rods adopts integral forging technology combined with special heat treatment technology, which increases the tensile strength of the connecting rods to 1.3 times that of traditional products, effectively avoiding deformation and fracture problems under heavy load conditions. At the same time, the optimized connecting rod small end bushing design reduces friction loss with the piston pin and improves operation stability.
At present, this series of connecting rods has completed multi-model adaptation tests. Field applications in mining, heavy-duty transportation and other conditions show that the engine connecting rod failure rate has decreased by 40%, and equipment operation reliability has been significantly improved. With the growth of market demand, the product has gradually realized large-scale supply, providing more reliable parts options for heavy-duty construction machinery users.
