The third-generation of HI servo-controlled hydrostatic pumps, PVG 100 electro-hydraulic proportional valves, and the PLUS 1 electronic communications network from Sauer-Danfoss are claimed to bring a new dimension of connectivity and performance.
The HI family is designed to bring “intelligent incorporation of the propulsion drive into machine management architecture”, and expand the functionality of the vehicle.
HI is said to be suited for medium and high power mobile markets. The initial product release is a single pump configuration with displacements of 147cc/rev and 165cc/rev. Additional releases in mid-2005 will include: 78 cc/rev, 45cc/rev and 53cc/rev. The 45cc and 53cc will be available in both single and tandem pump configurations.
The PVG 100 valve is designed to electronically optimise interfaces with mobile machinery. As a load independent proportional valve, it is said to provide equitable flow under all load and supply conditions, with post-compensated flow-sharing technology. Effective working pressures for PVG 100 are up to 350bar (5076psi); compensated flow to 180lpm (48gpm) with return flows up to 360lpm (95gpm).
Using DSP technology and CAN communication, PLUS 1 is claimed to enable both OEMs and end users to customise mobile machinery control. The foundation of PLUS 1 is a line of micro-controller and input/output modules – along with PLUS 1 compatible joysticks and graphical terminals.
