Electrifying vehicles yields advantages such as reduced emissions, better performance and
more flexibility. While electric machines can directly drive the wheels or tracks of heavy-duty …

Self-contained electro-hydraulic cylinders have the potential to replace both conventional
hydraulic systems and the electro-mechanical counterparts enhancing energy efficiency …

This research paper presents the first part of a comparative analysis of a novel self-
contained electro-hydraulic cylinder with passive load-holding capability against a state of …

Multi-joint heavy-duty manipulators, such as working devices of hydraulic excavators, are
mostly driven by hydraulic cylinders. Poor energy efficiency of the hydraulic system results in …

Pump controlled and self-contained electro-hydraulic cylinder drives may improve energy
efficiency and reduce installation space compared to conventional valve solutions, while …

Electro-hydraulic differential cylinder drives with variable-speed displacement units as their
central transmission element are subject to an increasing focus in both industry and …

This paper considers the analysis and control strategy for a novel direct hydraulic cylinder
drive, that is over-actuated in the sense that it has more inputs than sensible outputs. Efforts …

Since the energy crisis, the further development of a variable speed pump-controlled
hydraulic system driven by an electric machine has attracted increasing attention during the …

The introduction of low cost electric motor and drive solutions provides the possibility to
design cost competitive compact speed-variable drives as potentially feasible alternatives to …
