Advanced Technology of Automotive Connecting Rod
The present requirements for the connecting rod are indicated and the fracture splitting (FS) technologies for constructing the big end boss are reviewed. Two possibilities of FS for a high strength Cr-Mo steel and Ti alloys were discussed. The carburized quench-temper FS connecting rod has a superior fatigue strength with a high dimensional accuracy at the big end boss. The possibility of using a titanium FS connecting rod was examined and proposed.
