2. DIRAVI - Wikipedia

   en.wikipedia.org/wiki/DIRAVI

   The rack takes the form of a double acting hydraulic ram, but is capable of taking over full steering function in the event of a hydraulic failure. During normal operation the rack and pinion merely provides a position indication to the steering control valve through the pinion shaft. The rack and pinion do the actual steering only in the ...

3. Ship stability - Wikipedia

   en.wikipedia.org/wiki/Ship_stability

   Active stability systems, found on many vessels, require energy to be applied to the system in the form of pumps, hydraulic pistons, or electric actuators. They include stabilizer fins attached to the side of the vessel or tanks in which fluid is pumped around to counteract the vessel's motion.

4. Hydraulic pump - Wikipedia

   en.wikipedia.org/wiki/Hydraulic_pump

   These pumps are used for high flows at relatively low pressure (max 100 bars (10,000 kPa)). [clarification needed] They were used on board ships where a constant pressure hydraulic system extended through the whole ship, especially to control ball valves [clarification needed] but also to help drive the steering gear and other systems. The ...

5. Schottel (company) - Wikipedia

   en.wikipedia.org/wiki/Schottel_(company)

   Schottel is a manufacturer of propulsion and steering systems for ships and offshore applications. The company founder Josef Becker invented the rudderpropeller, a z-drive, in 1950. Today the company develops and manufactures azimuth propulsion, maneuvering and steering systems. In 2014 the subsidiary Schottel Hydro was founded to bundle up the ...

6. Variable displacement pump - Wikipedia

   en.wikipedia.org/wiki/Variable_displacement_pump

   A common type of variable-displacement pump used in vehicle technology is the axial piston pump. This pump has several pistons in cylinders arranged parallel to each other and rotating around a central shaft. A swashplate at one end is connected to the pistons. As the pistons rotate, the angle of the plate causes them to move in and out of ...

7. Cross-drive steering transmission - Wikipedia

   en.wikipedia.org/wiki/Cross-drive_steering...

   A later design of cross-drive transmission, the Allison X1100, was used in the 1970s experimental US MBT-70 and XM1 [3] tanks, then later adopted in the M1 Abrams.This adopts a different principle for the steering cross-coupling: instead of a hydro-dynamic torque converter, it uses a hydrostatic combination of a hydraulic pump and a hydraulic motor.
