Articulated truck steering

A steering apparatus for an articulated truck having a front portion, a rear portion, and an articulation joint between the front portion and the rear portion, the steering apparatus comprising:

• a hydraulic cylinder comprising a cylinder barrel and a piston movable within the cylinder barrel to steer the articulated truck by effecting a change in angle between the front portion and the rear portion;
• wherein the cylinder barrel comprises:
• a closed end including a primary hydraulic fluid passage for routing hydraulic fluid into and out of the cylinder barrel;
• and a snubbing tube projecting from the closed end into the cylinder barrel, wherein the primary hydraulic fluid passage opens into the cylinder barrel within the snubbing tube;
• wherein the piston comprises:
• a piston face configured to face the closed end of the cylinder barrel;
• and a snubbing aperture in the piston face, the snubbing aperture aligned with the snubbing tube and configured to receive the snubbing tube;
• wherein the snubbing tube comprises:
• a slot extending between an exterior of the snubbing tube and an interior of the snubbing tube and located at a distal end of the snubbing tube distant from the closed end of the cylinder barrel;
• and
• a plurality of channels extending between the exterior of the snubbing tube and the interior of the snubbing tube and located between the slot and the closed end of the cylinder barrel, each channel having a cross sectional area smaller than a cross sectional area of the slot.
