2. Power steering - Wikipedia

   en.wikipedia.org/wiki/Power_steering

   Power steering is a system for reducing a driver's effort to turn a steering wheel of a motor vehicle, by using a power source to assist steering. [1]Hydraulic or electric actuators add controlled energy to the steering mechanism, so the driver can provide less effort to turn the steered wheels when driving at typical speeds, and considerably reduce the physical effort necessary to turn the ...

3. Hydraulic fluid - Wikipedia

   en.wikipedia.org/wiki/Hydraulic_fluid

   A hydraulic fluid or hydraulic liquid is the medium by which power is transferred in hydraulic machinery. Common hydraulic fluids are based on mineral oil or water. [ 1 ] Examples of equipment that might use hydraulic fluids are excavators and backhoes , hydraulic brakes , power steering systems, automatic transmissions , garbage trucks ...

4. Steering - Wikipedia

   en.wikipedia.org/wiki/Steering

   A Hydraulic Power Steering (HPS) uses hydraulic pressure supplied by an engine-driven pump to assist the motion of turning the steering wheel. Electric Power Steering (EPS) is more efficient than hydraulic power-steering, since the electric power-steering motor only needs to provide assistance when the steering wheel is turned, whereas the ...

5. Cross-drive steering transmission - Wikipedia

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

   A cross-drive steering transmission is a transmission, used in tracked vehicles to allow precise and energy-efficient steering. It consists of the following main parts: two identical single-stage planetary gearings, a differential, a hydraulic pump connected to the engine (similar to an oil pump of cars), a hydraulic motor powered by the ...

6. Marine propulsion - Wikipedia

   en.wikipedia.org/wiki/Marine_propulsion

   The rotating crankshaft can be directly coupled to the propeller with slow speed engines, via a reduction gearbox for medium and high speed engines, or via an alternator and electric motor in diesel-electric vessels. The rotation of the crankshaft is connected to the camshaft or a hydraulic pump on an intelligent diesel.

7. DIRAVI - Wikipedia

   en.wikipedia.org/wiki/DIRAVI

   Fully hydraulic (no direct mechanical connection between the steering wheel shaft and the steering pinion during normal operation). Specifically it is hydrostatic, and the angle of the steering/road wheels is hydrostatically locked solid by the angle chosen at the steering wheel - just like the hydrostatic ram of a bulldozer: no road disturbance/force can disturb it.
