Data Sheet
Hydraulic Steering Unit
OSPD
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.
Features
•
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 fulfil 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.
•
Low noise.
•
One or several built in valve functions
possible: pressure relief, shock and
suction in L + R, Non-return in P and in
LS.
Applications
•
Larger tractors
•
Combines
•
Backhoe loaders
•
Telescopic handlers
•
Wheel loaders etc.
