I take it that the Flexidyne works somewhat like a bicycle pedal & wheel?
Actually, I’m not sure exactly how a bicycle hub works. I assume that a bicycle hub is a type of “sprag clutch” in which case the Flexidyne is not the same. Here is a description of how the Flexidyne-drive shaft works (it is difficult to describe without diagrams). The Flexidyne was invented in France and is used in industry as a “torque-limiting, slip clutch” during the start up cycle of high-inertia, electric motor-driven, industrial equipment such as conveyor belts, bark chippers, mixers, etc. It was originally known as a “PowderMatic” transmission.
