Technology meets future.

Hydraulic positioning unit

A hydraulic positioning unit was developed to enable a linear feed with electrically limited minimum and maximum adjustment travel, infinitely adjustable feed speed and monitoring of the position over the entire feed range, whereby the tensile and compressive force can be freely selected and monitored.
1987

Task:

  • Hydraulic linear feed with electrically limited minimum and maximum adjustment travel
  • The feed speed should be infinitely adjustable
  • Continuous monitoring of the respective position over the entire feed range
  • Tensile and compressive force can be freely selected; the set limit value must be monitored

 

Solution:

The minimum and maximum adjustment travel can be set independently of each other using a special adjustment circuit. The adjustment range of the minimum travel limit is 0 to 50 % of the total travel. The adjustment range of the max. travel limitation is 50 to 100 % of the total travel.

 

Possible applications

  • Shifting device for transmission test benches (manual and automatic transmissions)
  • Throttle cable
  • Integration into a program sequence in which valves or gate valves must be set in a defined manner
