The OSPD is a dual displacement steering unit, which assures easy maneuverability of machines of most sizes. Each unit in the complete steering range combines superior performance with the highest standards of safety, operator comfort and low noise levels. Due to flexibility in combination of rotary meters, OSPD can be offered with many different ratios between emergency steering and normal steering displacement, ratios between 1:2 and 1:7. OSPD also can be offered with external shift of displacement. In this way can be selected between different displacements to improve comfort and productivity.
The OSPD has 2 rotary meters (gear wheel sets). In the case of no pump supply only one rotary meter is active for emergency steering. In normal steering situations both rotary meters are active
With OSPD even heavy vehicles can in many cases fulfill legislations and be steered without the emergency steering pump
Ratio between normal steering displacement and emergency steering displacement from factor 2 up to 7
Low steering torque 0.8 to 3.0 N
m [7.08 to 26.55 lbf
in] in normal steering situations
One or several built in valve functions possible: pressure relief, shock and suction in L + R, Non-return in P and in LS
