The number one challenge in hydraulic transmission technology is low energy efficiency, mainly resulting from the extensive use of throttle valves for flow control. An approach to improve energy efficiency is to replace throttle valves with variable-speed electro-hydraulic drives, featuring highly reduced throttle losses, four quadrant operation, high dynamics and compatibility with current electrification trends, making such drives suitable in electrified machinery and so forth.
The reduced throttling limits fluid degasification requirements, hence fluid reservoirs can be reduced significantly which in turn increases the system level power density compared to conventional technology.
Variable-speed drives may be realized as standalone self-contained drives or as networks of multiple variable-speed drives sharing electric power supplies and/or hydraulic transmission lines enabling power sharing and energy recuperation.
The tight integration and dependency of components and reduced fluid volumes in variable-speed drive systems pose a new challenge; namely sensitivity to fluid leakages, fluid contamination, component degradation which ultimately may lead to drive functionality loss. Hence, feasibility of the technology necessitates the realization of online prognosis tools enabling maintenance prediction and prognostic control, allowing to negate fluid and component degradation increase, and thereby maintaining drive operation at a certain level to limit production loss.
