New hydraulic technology for efficient machine steering

Naseem Daher and Monika Ivantysynova describe an energy-efficient steering technology that has been implemented on a wheel loader. This new steering system has decreased fuel consumption by 15%, increased machine productivity by 23%, and boosted overall fuel efficiency by 43%. These results are aligned with the goals of the mobile machinery industry in which reducing fuel consumption and increasing machine productivity are of importance to both original equipment manufacturers (OEMs) and their end customers. A revolutionary technology that has proven to be an energy-efficient alternative to valve control is available. This technology, known as pump displacement controlled (DC) actuation, improves energy efficiency by eliminating control valves for high-power motion control and uses a variable-displacement pump to regulate the hydraulic flow rate.
