A driving force transmission control system (1) includes: an electric motor (5); a multi-disc clutch (8); a cam mechanism (3) that converts rotation output from the electric motor (5) into cam thrust force that is axial force in the axial direction of the ...

The assembly (10) has an input area (16) rotatably driven around an axis of rotation, and an output area (18). Two torque transmission paths are provided between the input and output areas, and a coupling assembly (24) superimposes torques conducted via th...
