Abstract:
1. A hydraulic steering actuator comprising: a cylinder and piston rod reciprocatingly mounted within the cylinder and extending through the cylinder for movement along a piston rod axis; a pair of spaced-apart cylinder arms extending radially outward of the cylinder and a pivot plate extending between the cylinder arms; a pair of support arms which are pivotable about a tilt axis and are connected to opposite ends of the piston rod to allow arcuate movement of the piston rod about the tilt axis while maintaining the piston rod axis parallel to the tilt rod axis; and a tie bar mount connected to the cylinder by a first connecting member, the tie bar mount having an aperture extending therethrough, wherein the aperture extends axially in a direction substantially perpendicular to the piston rod axis and a tie bar is connected to the tie bar mount by a second connecting member that extends through the aperture.
