Publication number: 20200240474Abstract: A polygonal coupling couples torque source to a torque consumer such that input and output portions of the coupling may elastically rotate relative to one another during torque transfer to accommodate rotational speed variations in delivery of torque from the torque source. In an embodiment the torque source is an internal combustion engine with an integrated switchable coupling between the engine crankshaft and a torque transfer segment supporting a motor-generator. The polygonal coupling includes axially-overlapping polygonal-shaped male and female portions which cooperate to pass torque between the output of the integrated switchable coupling and an input of the torque transfer segment. At least one of the male and female portions includes recesses which form flexible arms adjacent to the lobes of the polygonal shape that allow the portions to rotate relative to one another over small angular displacements, and thereby improve damping of crankshaft rotational vibrations.Type: ApplicationFiled: April 13, 2020Publication date: July 30, 2020Inventors: Sean J.

Publication number: 20200240478Abstract: A viscous clutch head may be replaced by selecting a viscous clutch head and a mount adapter. The viscous clutch head and the mount adapter may be selected from a group of universal modular fan drives and from a group of mount adapters. The mount adapter of a threaded type or a flange and bolt type may be selected. Depending on the viscous clutch head to be replaced, a fan adapter and/or a pilot adapter may also be selected from a group of fan adapters and from a group of pilot adapters. Accordingly, a range of models of viscous fan clutch systems may be replaced by using a limited number of parts. These parts may be stored on a tool cart. As different models of viscous fan clutch systems may be replaced using a limited number of parts, the in-stock inventory of replacement parts may be reduced.Type: ApplicationFiled: September 6, 2019Publication date: July 30, 2020Applicant: Kit MastersInventors: Craig SWANSON, Dale SCHERMAN
