Abstract: Embodiments include a pitch hydraulic system for a dual cabin articulated vehicle. The pitch hydraulic system includes an energy recovery function to harnesses hydraulic energy during vehicle mobility. A directional valve can be activated to allow movement of first and second pitch cylinders into either a “pitch up” or “pitch down” position. The pitch system can alter the stiffness of the unit to improve safety, stability and ride comfort.
