The Effect Of Drag Link Bending Radius On Fatigue Life And Static Forces Strength

Abstract

In heavy commercial vehicles, The parts that transfer the movement in the steering box to the wheels are called drag links. Drag links are bent in different geometries due to vehicle designs and other components in the steering system. Drag links are exposed to repeated tension and compression forces on the vehicle depending on the road conditions and the loads on the vehicle. In this study, static buckling forces and fatigue behavior of a drag link were determined according to different bending radii and the effect of bending radius on drag link life was investigated.
