Abstract
A steering system includes a drag link having a first support bushing opposite a second support bushing, a first steering hydraulic cylinder operably connected to the drag link, a second steering hydraulic cylinder operably connected to the drag link, a first tie rod operably connected to the drag link, and a second tie rod operably connected to the drag link. Each of the first and second cylinders and first and second tie rods are arranged to apply a corresponding radial force that is distributed between the first and second support bushings. One or more of the first and second steering cylinders and/or the first and second tie rods is positioned relative to the drag link to minimize a net summation of the first and second cylinder radial forces and the first and second tie rod radial forces that are applied to the first and second support bushings.
