New electro-hydraulic control systems for mobile machinery
In mobile machinery, several hydraulic drives can be operated independently at the same time. The hydraulic control system has to distribute the hydraulic power among the actuators depending on their requirements. In the European market, load-sensing systems (LS) are often used to control the working hydraulics. These systems have reached a very high degree of development and exceed other systems in terms of their capability They are economically priced and reliable. However, they can be prone to oscillations in some cases and often demand high commissioning costs. The paper outlines a new electro-hydraulic control system for the working hydraulics of mobile machines. The new control system basically uses the command signals from the joysticks to control the volume flow delivered by the pump. The valves that control the flow for the actuators operate like flow dividers, again controlled by the joystick signal. The new electro-hydraulic system offers better energy efficiency, better controllability and a better damping than hydraulic-mechanical systems supplied today
