2. Automatic transmission fluid - Wikipedia

   en.wikipedia.org/wiki/Automatic_transmission_fluid

   Oil pan of an automatic transmission with sedimented wear. Using a lint-free white rag to wipe the dipstick on automatic transmissions is advised so that the color of the fluid can be checked. Dark brown or black ATF can be an indicator of a transmission problem, vehicle abuse, or fluid that has far exceeded its useful life.

3. Hydraulic fluid - Wikipedia

   en.wikipedia.org/wiki/Hydraulic_fluid

   Power steering fluid is a sub type of hydraulic fluid. Most are mineral oil or silicone based fluids, while some use automatic transmission fluid, made from synthetic base oil. [8] [9] Automatic transmissions use fluids for their lubrication, cooling and hydraulic properties for viscous couplings. Use of the wrong type of fluid can lead to ...

4. 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 ...

5. Gear oil - Wikipedia

   en.wikipedia.org/wiki/Gear_oil

   Some modern automatic transaxles (integrated transmission and differential) do not use a heavy oil at all but lubricate with the lower viscosity hydraulic fluid, which is available at pressure within the automatic transmission. Gear oils account for about 20% of the lubricant market. [1]

6. Cross-drive steering transmission - Wikipedia

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

   Transmission of M47 Patton II, probably CD-850-4. 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 ...

8. Fluid coupling - Wikipedia

   en.wikipedia.org/wiki/Fluid_coupling

   A fluid coupling cannot develop output torque when the input and output angular velocities are identical. [7] Hence, a fluid coupling cannot achieve 100 percent power transmission efficiency. Due to slippage that will occur in any fluid coupling under load, some power will always be lost in fluid friction and turbulence, and dissipated as heat.

9. Health and environmental impact of the petroleum industry

   en.wikipedia.org/wiki/Health_and_environmental...

   Waste oil is oil containing not only breakdown products but also impurities from use. Some examples of waste oil are used oils such as hydraulic oil, transmission oil, brake fluids, motor oil, crankcase oil, gear box oil and synthetic oil. [53] Many of the same problems associated with natural petroleum exist with waste oil. When waste oil from ...
