Abstract: The shaft fork is one of the key components in the steering drive axle, and its structure rationality directly affects the steering and bearing performance of the whole axle. From the structural design, material selection, motion check and calculation analysis of an 18 t steering drive axle shaft fork, the paper expounds the design and analysis process of the shaft fork in detail, and determines the feasibility of the design product from the simulation aspect through finite element analysis, which provides the method and theoretical support for the design and analysis of similar products.
