Propellers, or fans, or whatever you want to call them.
A propeller that is attached to the drive mechanism spins a fluid (liquid or gas), which in turn spins a propeller that is attached to the load. The pitch of the blades of the two propellers can produce the same effect as gear reduction, so the two propellers can spin at different speeds.
When fluid drive is used on an automobile, the drive propeller (attached to the engine) spins faster than the load propeller (attached to the wheels). Thus the engine can run at the high speeds it needs to produce maximum power output without sending the car off a cliff.

Fluid Coupling
2016-10-07 07:01:04 · answer #2 · answered by ? 4 · 0⤊ 0⤋
A fluid coupling is a hydraulic device used for transmitting mechanical shaft power from a rotating driver to a rotating driven load. It has been used in automobile transmissions as an alternative to a mechanical clutch. It also has widespread application in marine and heavy industry. It is generally used in mechanical applications which require adjustable speed operation or controlled start-up without resulting in shock loading of the power transmission system.
A fluid coupling is a sealed chamber containing two toroids in a bath of hydraulic fluid. The driving toroid, called (the pump), rotates and the motion of its radial chambers imparts a centripetal motion to the hydraulic fluid. The moving fluid reaches the center of the driven toroid the impeller or turbine, where Coriolis force reaction transfers the angular momentum outward, applying a twisting force (torque) to rotate the pump in the same direction as the turbine. The fluid leaving the outer edges of the pump returns to the turbine, where its cycle begins again.
A fluid coupling is never 100% efficient: some of the motion of the turbine is lost to friction (transformed to heat) within the hydraulic fluid. As a result, the turbine always spins faster than the pump. This speed difference is called slip. Additionally, because the fluid returning to the turbine is moving in the opposite direction of the turbine's rotation, it causes some braking effect, further reducing efficiency.

It is freezing cold out and I tried to use my washer fluid yesterday on 2008 Ford Explorer. The pump made noise, but no fluid came out. The sensor never said the fluid was low, but when I got home I filled the reservoir up, but now the pump doesn't make any noise at all. The car jolts to let me know its pushing power to try and power the pump, but no noise from the pump or fluid coming out. Could the pump motor be frozen since I could hear it running yesterday? Please help!
