The Composition and Characteristics of an Automotive Steering Knuckle

The steering knuckle has a rather complex structure, integrating features from various parts such as shafts, sleeves, disc rings, and forks. The steering knuckle mainly comprises three core components: the support journal, the flange, and the fork. The support journal, designed as a stepped shaft, integrates various components including an outer cylindrical surface, a conical surface, a threaded surface, as well as shoulders, transition fillets, and end faces, forming a rotating body. The flange includes a flange face, evenly distributed bolt holes, and threaded holes for steering positioning. The fork is ingeniously formed by the combination of the upper and lower ears of the steering knuckle and the flange face.
