Geometric synthesis method for function generation of steering control mechanism with four positions
The aim of this paper is to introduce a geometric synthesis process of steering control mechanism for four positions, intended for function generation. The steering control linkage is a part of the steering system. It can be regarded as a spatial four-bar linkage (RSSR) and is used in most modern land vehicles, like tractors. Through the study of the spatial kinematic rules of geometric elements, the geometric relationship among the kinematic rules of the geometric elements with two, three and four positions is established, and the kinematic problems can be converted into geometric problems. Then, using the two-plane projection system, the spatial synthesis problem is transformed into planar geometric problem. Finally, combining the transformation of the projection plane, the synthesis result can be easily found in the projection plane.
