Patent ID: 10982723

Abstract:
Friction clutch assemblies with low-drag clutch packs having cone-clutch synchronizers and dog-clutch bypass devices are presented. A friction clutch assembly includes a housing that drivingly couples to an output (or input) member, and a disc hub rotatably mounted inside the housing that drivingly couples to the input (or output) member. A disc carrier is rotatably and slidably mounted inside the housing coaxial with the disc hub. A clutch pack includes reaction plates secured to the housing (or disc carrier) for common rotation therewith, and friction plates interleaved with the reaction plates and secured to the disc carrier (or housing) for common rotation therewith. A cone clutch is interposed between the clutch pack and disc hub such that frictional engagement of the cone clutch with the disc hub allows for compression of the pack to carry torque from the input member, through the disc hub and housing, to the output member.
