The steering knuckle comprises an annular topological structure, a disc body and a front shaft, the annular topological structure and the front shaft are connected to the two sides of the disc body respectively, two pin holes are formed in the annular topological structure, and the two pin holes are located in the same axis; a curved surface defined by the end of the outer side of the annular topological structure is in a saddle-shaped hyperboloid shape, and the two pin holes are formed in the protruding positions of the saddle-shaped hyperboloid. The invention further discloses a design method of the steering knuckle. The obtained steering knuckle is reasonable in structure, and the problems that in the prior art, after the roots of the vertical ribs on the steering knuckle are fractured, cracks are enlarged, and the whole part loses efficacy can be solved.

    本发明公开了一种转向节,包括:环形拓扑结构、盘体、前轴,环形拓扑结构、前轴分别连接在盘体两侧,环形拓扑结构上设置有两个销孔,两个销孔位于同一个轴线上;环形拓扑结构外侧端部围成的曲面为马鞍形双曲面形,两个销孔设置在马鞍形双曲面的凸起位置。本发明还公开了一种转向节的设计方法。本发明得到的转向节的结构合理,能够避免现有技术中转向节上立筋根部断裂后,引发的裂纹扩大,部件整体失效的问题。
