  7. 5. On Electrified Fluid Power Systems in Mobile Machinery

    Författare :Samuel Kärnell; Liselott Ericson; Petter Krus; Rudolf Scheidl; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fluid power; Electrification; Variable displacement; Pump-controlled systems;

    Sammanfattning : High power density in combination with flexible power distribution possibilities and extreme robustness are reasons why fluid power has been the preferred technology in mobile machinery, such as excavators and cranes, since the mid-20th century. In principle, the machines have been powered by a combustion engine which powers a pump, with the output from the pump being distributed to different functions via valves. LÄS MER
