Abstract [en]

In mobile hydraulics double acting, two chamber, asymmetrical hydraulic cylinders are commonly used for linear motioncontrol. This paper shows how a cylinder instead using four chambers can improve fuel efficiency in construction machinery.In addition to this special multi-chamber cylinder the hydraulic systems presented in this study involves the use of discretelycontrolled on/off valves, hydraulic accumulators and secondary controlled hydraulic motors. The proposed system solutionsupports potential and kinetic energy recovery and storage using hydraulic accumulators. Through proper sizing of compon-ents and sophisticated control of simple on/off valves an energy efficient, flexible and robust system is achieved. This paperoutlines the basics behind this concept and provides some examples as to how the technology can be useful with an ambitionto reach new levels of energy efficiency in construction machines.
