Incredible, No slip. But how is it connected? It obviously has to be connected so it wont bend right…DUH? Thanks for putting it up…learned a lot..videos always beat paragraphs.. Btw: This is what all automatic trannies use right?
Hello HYPHYDUM408, depending on the fluid coupling type the coupling shafts are i.e. connected to the motor and gearbox simply by flexible connecting couplings. Further there is a small slip between the pump wheel and turbine wheel – otherwiese there wouldn’t be a powertransmission between primary and secondary wheel. By the way, on the Voith Turbo website you can order a CD-ROM with much more information onm and animations on fill-controlled fluid couplings.
I don’t know where you got the idea that it was suppose onm to be 100% efficient. The video said that the slip can reach 100%. That means the output speed is zero while the input is still running. It won’t run there for long. 100% slip would cause the temperature of the fluid to sky rocket in a very short time.

There are losses in the bearings and through the tube that controls the internal fill level. There are also heat losses. The oil in the fluid coupling will get very hot. A heat exchanger is required to remove that heat. The efficiency and generated heat is a function of how much the coupling slips.
