A fluid coupling or hydraulic coupling or fluid flywheel is a device used to transmit rotating mechanical power. It has been used in automobile transmissions as an alternative to a mechanical clutch. It is simpler than a torque converter, but it does not provide any torque multiplication, so it must be used together with a gearbox.

Questions and Answers
Q: What is a fluid coupling?
A: A fluid coupling is a device that is used to transmit rotating mechanical power.
Q: What are the other names for a fluid coupling?
A: The other names for a fluid coupling are hydraulic coupling or fluid flywheel.
Q: How is a fluid coupling used in automobile transmissions?
A: A fluid coupling is used in automobile transmissions as an alternative to a mechanical clutch.
Q: What is the difference between a fluid coupling and a torque converter?
A: The difference between a fluid coupling and a torque converter is that a torque converter provides torque multiplication, while a fluid coupling doesn't.
Q: Does a fluid coupling require a gearbox to function?
A: Yes, a fluid coupling requires a gearbox to function because it does not provide any torque multiplication.
Q: Is a fluid coupling simpler or more complex than a torque converter?
A: A fluid coupling is simpler than a torque converter.
Q: Can a fluid coupling be used without a gearbox?
A: No, a fluid coupling cannot be used without a gearbox because it does not provide any torque multiplication.
