What is the purpose of the Flexidyne coupling?
The purpose of the Flexidyne in the Mini-IMP drive train is to act as a torque limiting, “slip-clutch” device which slips ONLY during initial engine start and most importantly when the engine is accelerating or decelerating through various narrow RPM ranges at which a highly destructive, torsional resonant feedback occurs. At all other engine speeds, the Flexidyne is “locked up” and operates with no slippage and thus no power loss or heat. You can think of the Flexidyne as the mechanical analog of an electrical diode. It is a device which permits the transmission of power in one direction but not in the other.
