Speed variable pump drives are propulsion systems of hydrostatic pumps that are able to adjust their rotary speed properly in order to change the pump’s flow rate. This leads to energetic and/or dynamic advantages in hydraulic systems using fixed or variable displacement pumps. At the TU Braunschweig, transmission concepts were tested for speed-variable pump drives, which are supposed to transfer the advantages estimated in stationary hydraulics to mobile applications.

Speed Variable Pump Drives

Since the mid-90ies there are research activities on speed variable pump drives for stationary applications in order to provide appropriate hydraulic power. These supply units consist of a frequency controlled electric motor (EM) and a corresponding fixed or variable displacement pump. The dynamics as well as the characteristics of losses were examined by [1, 2, 3, 4] in detail. Enhancement in efficiency and partly in dynamics are possible in considered working cycles. Speed variable operation...
