Hydraulic Positioning Unit

Task:

Hydraulic linear forward feed with electric minimal and maximal displacement limitation.
Advance speed to be steplessly variable.
Permanent position control over total feed range.
Free selection of push and pull force; max./min. value control.

Solution:

Minimal and maximal displacment may be selected independently with special regulator.
Regulating range of min. displacement is 0-50% of total travel.
Regulating range of max. displacement is 50-100% of total travel.

Use:

Switchgear for gear test stands (gearbox, automatic transmission)
Accelerator pedal
Integration into program demanding defined selection of valves resp. gates

Technical Data:

speed: steplessly variable from 0.1…..1m/s
positioning accuracy: +/- 0.1 mm
positioning control: +/- 0.2 mm
displacement measuring system: inductive
